    DESCRIPTION TITLE OF INVENTION Compositions for alleviating ultraviolet irradiation-induced damages TECHNICAL FIELD [0001] The present invention relates to a composition for alleviating an ultraviolet irradiation-induced damage comprising one or more compounds selected from the group consisting of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine and derivatives and/or salts thereof, a method for improving an ultraviolet radiation exposure-induced dermal disease and a dermal aesthetic condition comprising a step of administering one or more compounds selected from the group consisting of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine and derivatives and/or salts thereof, and a method for treating and/or preventing a cataract comprising a step of administering the compound described above. Background Art [0002] Ultraviolet rays are classified into long wavelength region ultraviolet rays of longer than about 320 nm (UV-A), medium wavelength region ultraviolet rays of about 320 to about 1 280 nm (UV-B) and short wavelength region ultraviolet rays of shorter than about 280 nm (UV-C) . Among these, the UV-C is not contained in solar lights reaching the ground since it is absorbed by ozone layers. The UV-A is not absorbed by the ozone layers and predominant in the ultraviolet rays reaching the ground. While the UV-B is partly absorbed by the ozone layers, it causes a skin damage at one-thousandth dose of the UV-A. Accordingly, both of the UV-A and the UV-B are important as major causes of the skin damages. Non-Patent Literature 1 discloses diseases in which the ultraviolet rays are implicated, including wrinkles, erythema, xeroderma pigmentosum, chronic actinic dermatitis, squamous cell carcinoma, basal cell carcinoma, malignant melanoma, Bowen disease, solar keratosis, photodermatosis, hydroa vacciniforme and photocontact dermatitis, while Non-Patent Literature 2 exemplifies solar dermatitis, chronic actinic dermatopathy, actinic keratosis, actinic cheilitis, Favre-Racouchot syndrome, photodermatosis, photocontact dermatitis, berloque dermatitis, photosensitive drug eruption, polymorphous light eruption, hydroa vacciniforme, solar urticaria, chronic photosensitive dermatitis, xerode:rma pigmentosum, ephelides, porphyria, pellagra, Hartnup disease, solar keratosis, dermatomyositis, lichen planus, Darier disease, pityriasis rubra pilaris, rosacea, atopic dermatitis, chloasma, prurigo simplex and lupus erythematosus. 2 PRIOR ART DOCUMENTS Non-Patent Documents [0003] Non-Patent document 1: "HIHUSHIKKAN SAISHIN NO CHIRYO (Latest methods for treating dermal diseases) ", 2005-2006 (Nankodo Co., Ltd.) Non-Patent document 2: "HYOJUN HIHUKAGAKU (Standard dermatology)", 7th edition (Igaku-Shoin Ltd.) Disclosure of the Invention PROBLEM TO BE SOLVED BY THE INVENTION [0004] Known conventional prophylactic and/or therapeutic agents for an ultraviolet irradiation-induced skin damage include an ultraviolet scattering agent which inhibits absorption of the ultraviolet by a skin , such as titanium oxide, an ultraviolet absorber , such as ethyl hexyl p-methoxycinnamic acid, or an antioxidant which removes a free radical generated by the ultraviolet. The ultraviolet scattering agent or the ultraviolet absorber is, however, not used everyday routinely although it is effective outdoor in preventing sunburn. The antioxidant is problematic in terms of stability and safety. In addition, known therapeutic agents for the ultraviolet irradiation-induced skin damages are limited only to symptomatic therapeutic agents. Accordingly, it is required 3 to develop a prophylactic and/or therapeutic agent for an ultraviolet irradiation-induced skin damage which can routinely be used and which is stable and safe, as well as pharmaceutical, cosmetic and food products containing the same.

[0024] In the method for treating and/or preventing a cataract according to the invention, the cataract described above may 8 be a senile cataract. [0025] In the description, a "salt" means any salt including a metal salt, an amine salt and the like, provided that the alleviating effect on ultraviolet irradiation-induced damage of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine is not reduced. The metal salt described above may include an alkaline metal salt, an alkaline earth metal salt and the like. The amine salt described above may include a triethylamine salt, a benzylamine salt and the like. [0026] As used herein, "derivative thereof" means D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine each bound covalently at its amino group, carboxyl group or side chain with any substituent group, provided that the alleviating effect on ultraviolet irradiation-induced damage of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine is not reduced. The substituent group mentioned above includes, but is not limited to, a protective group , such as an N-phenylacetyl group, a 4,4'-dimethoxytrityl (DMT) group,etc.; a biological macromolecule , such as a protein, a peptide, a saccharide, a lipid, a nucleic acid, etc.; a synthetic polymer , such as a polystyrene, a polyethylene, a polyvinyl, a polyester,etc.; and a functional group such as an ester group, etc. The ester group mentioned above may include, 9 for example, a methyl ester, an ethyl ester, -other aliphatic ester or aromatic ester. [0027] Since an amino acid can exist as an optical isomer which is an L-form or a D-form but a natural protein has L-amino acids bound via peptide bonds and only L-amino acids are employed excluding some exceptions such as a bacterial cell wall, it has been considered that in a mammal including a human only L-amino acids are present and utilized (Kinouchi, T. et al., TANPAKUSHITSU KAKUSAN KOSO (Proteins, nucleic acids and enzymes), 50:453-460(2005), Lehninger Principles of Biochemistry [Vol.1] 2nd ed., pp132-147(1993), Hirokawa Publishing Co., Harper's Biochemistry, Original version, 22nd ed., pp 2 l- 3 0(1 9 9 1), Maruzen Co., Ltd.). Accordingly, only L-amino acids have mostly been employed as amino acids academically and industrially for a long time. [0028] An exceptional case where a D-amino acid is employed may, for example, be a case of using as a starting material for an antibiotics produced by a microorganism and a case of a food additive employing a D-amino acid in a DL-amino acid mixture just for the purpose of reducing cost of fractionating only an L-amino acid from a mixture of the L-amino acid and the D-amino acid. Nevertheless, there has been no case of using a free or single body of D-arnino acid industrially as a bioactive 10 substance. (0029] It was reported recently that D-serine and D-asparatic acid have bioactivities and that even in human a D-serine racemase is present and it was revealed that also in a mammal a D-amino acid is present in the body where it exerts a bioactivity. However, since entirely different bioactivities are observed between D-serine and L-serine as well as D-aspartic acid and L-aspartic acid in which the bioactivity is observed in a human, it is obvious that a D-amino acid should be handled as a substance which is different from an L-amino acid and the conventional findings with regard to amino acids should be understood as the findings with regard to L-amino acids. [0030] As indicated in Examples described below, L-proline has no alleviating effect on ultraviolet irradiation-induced damage, and any alleviating effect on ultraviolet irradiation-induced damage of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine is not known so far. Accordingly, a composition for alleviating an ultraviolet irradiation-induced damage comprising one or more compounds selected from the group consisting of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine according to the invention is a novel invention. [0031] 11 Recently, it was reported that ddY mice were allowed to access a 10 mM aqueous solution of a D-amino acid for 2 weeks and then examined for the D-amino acid concentration in each organ, which was 3 to 1000 pmol per gland in a pineal body and 2 to 500 nmol per wet gram in a brain tissue (Morikawa, A. et al., Amino Acids, 32:13-20 (2007) ) . Based on this, the lower limit of daily intake of L- or D-glutamic acid, D-proline, L or D-cysteine contained in a composition of the present invention was calculated. [0032] As indicated in Examples described below, L- and D-glutamic acids of the present invention exhibit, even when given as a single body, an alleviating effect on ultraviolet irradiation-induced damage at a concentration ranging from 0.1 to 100 pLM on cultured human keratinocyte and fibroblast. Accordingly, the amount of L- and/or D-glutamic acid contained in an composition of the present invention including pharmaceutical composition of the present invention, anti-wrinkle agent, sunscreen agent, cosmetic composition and food composition may vary in a wide range, provided that L and/or D-glutamic acid as a single body is delivered to a keratinocyte or a fibroblast in an in vivo skin tissue at a concentration in the range specified above. When the composition of the present invention is a skin formulation, then the L- and/or D-glutamic acid content may range from 0.000015% 12 by weight to 10% by weight in the total amount of the composition of the present invention, or to a maximum concentration by weight which is possible to be incorporated. Thus, when the composition of the present invention is a skin formulation, then the L- and/or D-glutamic acid content is preferably 0.00003% by weight to 0.3% by weight, most preferably 0.0003% by weight to 0.03% by weight. When the composition of the present invention is an internal formulation, the L- and/or D-glutamic acid content may be 0.00001% by weight to 100% by weight. When the composition of the present invention is an internal formulation, the L- and/or D-glutamic acid content is preferably 0.00002% by weight to 80% by weight, most preferably 0.0002% by weight to 60% by weight. The lower limit of the daily dose of D-glutamic acid contained in the composition of the present invention may be 0.01 ng, preferably 0.1 ng, more preferably 1 ngper kg body weight. The lower limit of the daily dose of L-glutamic acid contained in the composition of the present invention is less than a dose of a clinical drug (80 mg or more per kg body weight), and may be 0.1 mg, preferably 1 mg, more preferably 10 mg per kg body weight. [0033] As indicated in Examples described below, D-proline of the invention exhibits, even when given as a single body, an alleviating effect on ultraviolet irradiation-induced damage at a concentration ranging from 0.01 to 1 pM on a cultured human 13 fibroblast. Accordingly, the amount of D-proline contained in an pharmaceutical composition of the present invention, anti-wrinkle agent, sunscreen agent, cosmetic composition and food composition may vary in a wide range, provided that D-proline as a single body is delivered to a fibroblast in an in vivo skin tissue at a concentration in the range specified above. When the composition of the present invention is a skin formulation, then the D-proline content may range from 0.000015% by weight to 50% by weight in the total amount of the composition of the present invention, or to a maximum concentration by weight which is possible to be incorporated. Thus, when the composition is a skin formulation, then the D-proline content is preferably 0.00003% by weight to 30% by weight, most preferably 0.0003% by weight to 3% by weight. When the composition of the present invention is an internal formulation, the D-proline content may be 0.00001% by weight to 100% by weight. When the composition of the present invention is an internal formulation, the D-proline content is preferably 0.00002% by weight to 80% by weight, most preferably 0.0002% by weight to 60% by weight. The lower limit of the daily dose of D-proline contained in the composition of the present invention may be 0.01 ng, preferably 0.1 ng, more preferably 1 ng per kg body weight. [0034] As indicated in Examples described below, L- and 14 D-cysteines of the invention exhibit, even when given as a single body, an alleviating effect on ultraviolet irradiation-induced damage at a concentration ranging from 0. 1 to 100 ptM on cultured human keratinocyte and fibroblast. Accordingly, the amount of L- and/or D-cysteine contained in an composition of the present invention including pharmaceutical composition of the present invention, anti-wrinkle agent, sunscreen agent, cosmetic composition and food composition may vary in a wide range, provided that L and/or D-cysteine as a single body is delivered to a keratinocyte or a fibroblast in an in vivo skin tissue at a concentration in the range specified above. When the composition of the present invention is a skin formulation, then the L- and/or D-cysteine content may range from 0.000015% by weight to 10% by weight in the total amount of the composition of the present invention, or to a maximum concentration by weight which is possible to be incorporated. Thus, when the composition of the present invention is a skin formulation, then the L- and/or D-cysteine content is preferably 0.00003% by weight to 0.3% by weight, most preferably 0.0003% by weight to 0.03% by weight. When the composition of the present invention is an internal formulation, the L- and/or D-cysteine content may be 0.00001% by weight to 100% by weight. When the composition of the present invention is an internal formulation, the L- and/or D-cysteine content is preferably 0.00002% by 15 weight to 80% by weight, most preferably 0.0002% by weight to 60% by weight. The lower limit of the daily dose of D-cysteine contained in the composition of the present invention may be 0.01 ng, preferably 0.1 ng, more preferably 1 ng per kg body weight. The lower limit of the daily dose of L-cysteine contained in the composition of the present invention is less than a dose of a clinical drug (3 mg or more per kg body weight), and may be 0.01 mg, preferably 0.1 mg, more preferably 1 mg per kg body weight. [0035] The pharmaceutical composition of the present invention may further comprise, in addition to one or more compounds selected from the group consisting of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine each as a single body, salts of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine, and derivatives capable of being subjected to in vivo drug metabolizing enzymes and the like whereby liberating D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine, at least one pharmaceutically acceptable additive, provided that the alleviating effect on ultraviolet irradiation-induced damage of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine is not reduced. Such an additive includes, but is not limited to, a diluent, an extender, a binder, an adhesive, a lubricant, a glidant, a plasticizer, a disintegrant, a carrier 16 solvent, a buffering agent, a colorant, a flavor, a sweetener, a preservative, a stabilizer, an adsorbent, as well as other pharmaceutical additives known to those skilled in the art. [0036] An anti-wrinkle agent and/or a sunscreen agent of the invention can be prepared using only D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine each as a single body, salts of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine, and derivatives capable of being subjected to in vivo drug metabolizing enzymes and the like whereby liberating D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine. However, other components employed in skin formulations such as cosmetic and pharmaceutical products including quasi drugs may appropriately be incorporated as required to the extent that the effect of the invention is not reduced. Such other components (optionally incorporated components) include, for example, oils, surfactants, powders, colorants, water, alcohols, thickening agents, chelating agents, silicones, antioxidants, UV absorbers, humectants, fragrances, various pharmaceutically effective components, preservatives, pH adjusters, neutralizing agents. [0037] The skin formulation and the cosmetic composition of the present invention may be any of those employed conventionally 17 in a skin formulation and a cosmetic composition, such as an ointment, a cream, an emulsion, a lotion, a pack, a bath salt and the like, and their dosage forms are not specified particularly. [0038] The cosmetic composition of the present invention may appropriately contain other components employed in skin formulations , such as cosmetic and pharmaceutical products including quasi drugs, provided that the alleviating effect on ultraviolet irradiation-induced damage of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine is not reduced. Such other components (optionally incorporated components) include, for example, oils, surfactants, powders, colorants, water, alcohols, thickening agents, chelating agents, silicones, antioxidants, UV absorbers, humectants, fragrances, various pharmaceutically effective components, preservatives, pH adjusters, neutralizing agents. [0039] The food composition of the present invention may further comprises, in addition to D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine each as a single body, salts of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine, and/or derivatives capable of being subjected to in vivo drug metabolizing enzymes and the like whereby liberating D-glutamic acid, L-glutamic acid, D-proline, 18 D-cysteine and L-cysteine, a food-industrially acceptable component , such as a seasoning, a colorant, a preservative, provided that the alleviating effect on ultraviolet irradiation-induced damage of D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine is not reduced. [0040] The food composition of the present invention may be any of those employed conventionally in a food composition , such as a beverage, a gummy candy, a candy, a tablet, to which it is not limited. [0041] An exposure to an ultraviolet ray is considered to be one of the causes not cnly of a dermal disease but also of an ophthalmic disease such as a cataract. A prolonged exposure of mice to an ultraviolet ray was reported to cause a turbidity in an anterior cortex of a lens, whereby allowing a cataract model to be obtained experimentally (Maeda, T. and Iwata, S., "SUISHOTAI SONO SEIKAGAKUTEKI KIKO (Lens, its biochemical mechanisms), p.318--323, Ed. by Iwata, S., Medical-Aoi Publishings, Inc., Tokyo (1986)) . Also, one of the causes of a senile cataract is considered to be an ultraviolet ray (Fujinaga, Y., "HAKUNAISHO (cataract), GANKA (ophthalmology) MOOK No.17", p.10, Ed. by Mishima et al., Kanehara & Co., Ltd., Tokyo (1982)), and Zigman et al. conducted an epidemiological surveillance in Manila, Tampa and Rochester and reported that 19 there was a correlation between the ultraviolet irradiation amount and the cataract incidence and the ultraviolet ray is a risk factor for the cataract (Zigman, S. et al., Invest. Ophthalmol. Visual Sci. 18:462-467 (1979) ) . Accordingly, these findings, combined with Examples described below, suggest that D-glutamic acid, L-glutamic acid, D-proline, D-cysteine and L-cysteine having an alleviating effect on ultraviolet irradiation-induced damage are effective in preventing or treating the cataract. 20 BRIEF DESCRIPTION OF THE DRAWINGS [0042] Figure 1 is a graph showing the effect of a D-glutamic acid treatment in normal human epidermal keratinocytes.

DESCRIPTION OF EMBODIMENTS [0043] Examples of the present invention described below are 21 intended only to exemplify the invention rather than to limit the scope thereof. The scope of the invention is limited only by the description in claims. Example 1 [0044] Alleviating effect on ultraviolet irradiation-induced damage of D-glutamic acid Cell The cell employed was a commercially available human neonatal epidermal keratinocyte (Cryo NHEK-Neo, Sanko-Junyaku Co., Ltd.). This cell was inoculated at 2 x 105 cells/mL to a commercially available culture dish of 35 mm in diameter coated with a type I collagen (COL1, Asahi Techno Glass Co., Ltd.), where it was cultured in a commercially available serum-free medium (Defined Keratinocyte-SFM, Gibco., hereinafter referred to as "ordinary medium 1"). This cell was cultured for 5 to 7 days in a 5% CO 2 and saturated water vapor atmosphere at 37*C until confluent while replacing the medium every 2 days. [0045] For examining the effect of adding glutamic acid before UV irradiation (hereinafter referred to as "pretreatment"), the culture medium was switched 24 hours before the irradiation to a medium supplemented with 0.1 to 100 ptM L- or D-glutamic acid. [0046] 22 UV Irradiation Before UV-B irradiation, the culture medium was replaced with 1 mL of PBS. The UV-B irradiation was conducted using a in-house made UV exposing device (two UV lamps, Toshiba Medical Supply Corporation, TOREX FL20S-E-30/DMR) by irradiating a UV ray of 280 nm to 320 nm at 75 J/cm 2 from 40 cm above a culture dish in a state where the lid of the respective culture dish was removed. The UV dose was measured using UV RADIOMETER UVR-3036/S (Topcon Corporation). [0047] The cell thus irradiated with UV was returned to the ordinary medium 1 where it was cultured in a 5% C02 and saturated water vapor atmosphere at 37 0 C for 21 hours. For examining the effect of adding glutamic acid after UV irradiation (hereinafter referred to as "posttreatment"), this 21-hour cultured medium was added with 0.1 to 100 tM L- or D-glutamic acid. [0048] Cell damage quantification Thereafter, the culture medium was supplemented with Alamar Blue (trade mark, Biosource International Inc.) at a final concentration of 10%, and its supernatant was examined for the fluorescent intensity 3 hours later with an excitation wavelength of 544 nm and a fluorescent wavelength of 590 nm as described by Ahmed S.A. et al. (J. Immunol. Method. 170, 211-224 23 (1994) ) and in accordance with the manufacture's instruction. [0049] Results Figure 1 shows the results of the experiment investigating the effect of D-glutamic acid on the cell damage in keratinocytes induced by the ultraviolet irradiation with the UV-B at 75 mJ/cm 2 . The error bars for relevant experimental conditions are the standard deviations of the measured values of the results of the experiments repeated eight times under identical conditions. The asterisk (**) indicates 2<1% in Bonferroni test. The fluorescent intensity of Alamar Blue (trademark) in the absence of the UV irradiation was about 22,000, which was reduced to 5,000 to 7,000 when the cell damage occurred due to the UV-B irradiation. Nevertheless, when D-glutamic acid was added, the fluorescent intensity was increased, and the cell damage was alleviated. While this cell damage alleviating effect was observed regardless of the time of the D-glutamic acid treatment which was before or after the UV irradiation, a higher concentration of D-glutamic acid yielded a higher alleviating effect. No cell damage alleviating effect was observed when adding L-glutamic acid (data not shown) Based on the results described above, D-glutamic acid alleviates the UV-B-induced cell damage in keratinocytes in a concentration dependent manner. Example 2 24 [0050] Alleviating effect cn ultraviolet irradiation-induced damage of D-proline Cell The cell employed was a commercially available human neonatal dermal fibroblast (Cryo NHDF-Neo, Sanko-Junyaku Co., Ltd.) . This cell was inoculated at 2 x 105 cells/mL to a commercially available culture dish of 35 mm in diameter (BD FALCON 353001, Beckton Dickinson Japan), where it was cultured in a commercially available cell culture medium (D-MEM (1 g/L glucose, Wako Pure Chemical Industries, Ltd. ) supplemented with 10% fetal bovine serum (hereinafter referred to as "ordinary medium 2") . This cell was cultured for about 24 hours in a 5%
    CO
    2 and saturated water vapor atmosphere at 37*C. [0051] Thereafter, the culture medium for culturing the cell described above was switched to 1 mL of a BSO medium containing a glutathione biosynthesis inhibitor BSO (L-buthionine-(S,R)-sulfoximine, Wako Pure Chemical Industries, Ltd.) at 1 x 10-3%, where the culture was conducted for about 24 hours in a 5% CO 2 and saturated water vapor atmosphere at 37'C. The BSO medium described above was prepared by a 200-fold dilution of a stock solution containing 0.2% BSO in ethyl alcohol with the ordinary medium 2 described above. [0052] 25 For examining the effect of adding proline before UV irradiation (hereinafter referred to as "pretreatment"), the culture medium was switched 24 hours before the irradiation to a medium supplemented with 0.1 tM L- or D-proline. [0053] UV Irradiation medium Ferric chloride (II) was dissolved in a distilled water at 2 x 10 3%, and the resultant solution was subjected to a 200-fold dilution (final concentration: 1 x 10-%) with a phosphate buffer solution PBS containing calcium ion and magnesium ion (PBS+) to obtain a medium (hereinafter referred to as "UV irradiation medium") , which was warmed preliminarily before use. [0054] UV Irradiation Before UV-A irradiation, the culture medium was replaced with 1 mL of the UV irradiation medium described above. The UV-A irradiation was conducted using a UV light uniform exposing device UVE-502S+EL-160 (SAN-EI ELECTRIC) by irradiating a UV ray of 320 nm to 400 nm at 15 J/cm 2 and 22.5 J/cm 2 from about 20 cm above a culture dish in a state where the lid of the respective culture dish was removed. The UV dose was measured using UV RADIOMETER UVR-3036/S (Topcon Corporation). [0055] Treatment with proline after UV irradiation 26 After UV irradiation, the cell was returned to the ordinary medium 2 described above where it was cultured in a 5% C02 and saturated water vapor atmosphere at 37*C for 21 hours. For examining the effect of adding proline after UV irradiation (hereinafter referred to as "posttreatment"), this 21-hour cultured medium was supplemented with 0.01 to 1000 p.M L- or D-proline. [0056] Quantification of cell damage upon posttreatment Thereafter, the fluorescent intensity was measured by a method described in Example 1. [0057] Results of posttreatment Figure 2 shows the results of the experiment investigating the effect of D-proline on the cell damage in fibroblasts induced by the ultraviolet irradiation with the UV-A at 15 J/cm 2 and 22.5 J/cm 2 . The error bars for relevant experimental conditions are the standard deviations of the measured values of the results of the experiments repeated four times under identical conditions. The asterisk (*) indicates p<5% in Bonferroni test. The fluorescent intensity of Alamar Blue (trademark) in the absence of the UV irradiation was about 12,000, which was reduced to about 5,000 when the cell damage occurred due to the UV-A irradiation at 15 J/cm 2 . It was also reduced to about 3,000 when the cell damage occurred due to the 27 UV-A irradiation at 22.5 J/cm 2 . Nevertheless, when D-proline was added, the fluorescent intensity was increased, and the cell damage was alleviated. (0058] Table 1 shows the results of the experiment investigating the effect of L- and D-proline on the cell damage in fibroblasts induced by the ultraviolet irradiation with the UV-A at 12.5 J/cm 2 and 15 J/cm2 . The error bars for relevant experimental conditions are the standard deviations of the measured values of the results of the experiments repeated four to six times under identical conditions. The asterisk (*) 1 shown here indicates p<0.1% when compared with a control and p=O.1% when compared with L-proline in Bonferroni test. The asterisk (*) 2 shown here indicates p<0.1% when compared with a control and p<5% when compared with L-proline in Bonferroni test. The fluorescent intensity of Alamar Blue (trademark) in the absence of the UV irradiation was about 12, 000, which was reduced to about 2, 500 and about 1, 000 when the cell damage occurred due to the UV-A irradiation at 12.5 J/cm 2 and the UV-A irradiation 2 at 15 J/cm , respectively. Almost no alleviation of the cell damage was noted when adding L-proline. Nevertheless, when D-proline was added, the fluorescent intensity was increased, and the cell damage was alleviated. [0059] [Table 1] 28 UV Fluorescent irradiation Control intensity L-proline (0.1 pM) amount D-proline (0.1 pM) (J/cm2) 0 12380 21 12270 ± 68 12211 77 12.5 2503 629 4615 1218 ' 2877 834 15 1018 89 2365 ± 648 *2 1552 ± 320 Mean i vs control P<0.001, SD;N=4-6 vs L-proline P<0.001 Bonferroni *2: vs control P<0.001, test vs L-proline P<0.05 [0060] Quantification of cell damage upon pretreatment The cell damage was quantified by detachment of the cell with a 0.25% trypsin-EDTA (Gibco) treatment for 5 minutes followed by centrifugation and washing, followed by a 0.2% trypan blue staining (Gibco) for verification of viability or death. [0061] Results of pretreatment Figure 3 shows the results of the experiment investigating the effect of D-proline on the cell damage in fibroblasts induced by the ultraviolet irradiation at 22. 5 J/cm 2 The error bars for relevant experimental conditions are the standard deviations of the measured values of the results of the experiments repeated four times under identical conditions. The asterisk (**) indicates p<l% in Bonferroni test. [0062] 29 The percentage of the viable cell in the absence of the UV irradiation was about 95%, which was reduced to about 30% when the cell damage occurred due to the UV-A irradiation at 22.5 J/cm 2 . Nevertheless, when D-proline was added, the percentage of the viable cell was increased to about 50%, and the cell death was alleviated. Based on the results described above, it was shown that the cell damage alleviating effect was independent of the time of the D-proline treatment, i.e., before or after the UV irradiation. Also it was shown that D-proline alleviates the UV-A-induced cell damage in a concentration dependent manner in the fibroblasts. Example 3 [0063] Comparison of alleviating effect on ultraviolet irradiation-induced damage between D-proline and D-glutamic acid Methods The cell employed was a commercially available human neonatal dermal fibroblast (Cryo NHDF-Neo, Sanko-Junyaku Co., Ltd.), which was cultured by the same method described in Example 2. For examining the effect of adding D-proline or D-glutamic acid before UV irradiation, the culture medium was switched 24 hours before the irradiation to a medium supplemented with 0. 1 JtM D-proline or 1 pM L- or D-glutamic acid. The UV irradiation to a medium without such amino acids served 30 as a control. The UV-A irradiation (22.5 J/cm 2 ) and the Alamar Blue (trade mark) cell damage quantification were conducted by the method described in Example 2. [0064] Results Figure 4 shows the results of the experiment investigating the effect of D-proline and L- or D-glutamic acid on the cell damage in fibroblasts induced by the UV-A 2 irradiation at 22.5 J/cm2. The error bars for relevant experimental conditions are the standard deviations of the measured values of the results of the experiments repeated four times under identical conditions. The asterisk (**) indicates p<1% in Bonferroni/Dunn test. [0065] The fluorescent intensity was about 1, 100 in the control. The fluorescent intensity in the presence of D-proline, L- or D-glutamic acid were about 1,750, about 1,100 or about 1,700, respectively. Based on these results, it was shown that D-proline and D-glutamic acid alleviate the UV-A-induced cell damage in the normal human dermal fibroblasts with a statistical significance. However, no cell damage alleviating effect was observed with L-glutamic acid. It was shown that D-proline alleviates the UV-induced cell damage at a concentration of one tenth when compared with D-glutamic acid. Example 4 31 [0066] Alleviating effect on ultraviolet irradiation-induced damage of L- and D-cysteines Cell The cell employed was a commercially available human neonatal epidermal keratinocyte (Cryo NHEK-Neo, Sanko-Junyaku Co., Ltd.). This cell was inoculated at 1 x 105 cells/mL to a commercially available culture dish of 35 mm in diameter coated with a type I collagen (COL1, Asahi Techno Glass Co., Ltd.). This cell was cultured in a commercially available serum-free medium (Defined Keratinocyte-SFM, Gibco., hereinafter referred to as "ordinary medium 3") supplemented with a proliferator (Defined Keratinocyte-SFM Growth Supplement, Gibco) and antibiotics (PSF: penicillin, streptomycin and fungison) for 3 days in a 5% CO 2 and saturated water vapor atmosphere at 37*C. Thereafter, it was cultured for 2 days in 2 mL of the ordinary medium 3 containing 100 iM D-alanine, D-serine, D-hydroxyproline, D-aspartic acid, D-cysteine or L-cysteine. As a control, the ordinary medium 3 containing PBS instead of the D-amino acid was added to the ordinary medium 3. [0067] UV Irradiation Before UV-B irradiation, the culture medium was replaced with 1 mL of PBS. The UV-B irradiation was conducted using a 32 in-house made UV exposing device (two UV lamps, Toshiba Medical Supply Corporation, TOREX FL20S-E-30/DMR) by irradiating a UV ray of 280 nm to 320 nm at 25 J/cm 2 from 40 cm above a culture dish in a state where the lid of the respective culture dish was removed. The UV dose was measured using UV RADIOMETER UVR-3036/S (Topcon Corporation). [0068] The cell thus irradiated with UV was cultured in 900 pL of the ordinary medium 3 containing 100 piM D-alanine, D-serine, D-hydroxyproline, D-aspartic acid, D-cysteine or L-cysteine in a 5% C02 and saturated water vapor atmosphere at 370C for 24 hours. [0069] Quantification of cell damage Thereafter, the fluorescent intensity was measured by the method described in Example 1. [0070] Results Figure 5 shows the results of the experiment investigating the effect of cysteine on the cell damage in keratinocytes induced by the ultraviolet irradiation with the UV-B at 25 mJ/cm2 . The error bars for relevant experimental conditions are the standard deviations of the measured values of the results of the experiments repeated four times under identical conditions. The asterisk (**) indicates p<l% in 33 Student's t test. The fluorescent intensity of Alamar Blue (trademark) after occurrence of the cell damage due to the UV-B irradiation was about 570 in the presence of D-alanine, and was about 550 in the absence of D-alanine. The fluorescent intensity in the presence of D-serine was about 490 while the fluorescent intensity in the absence of D-serine was about 500. The fluorescent intensity in the presence of D-hydroxyproline was about 550 while the fluorescent intensity in the absence of D-hydroxyproline was about 550. The fluorescent intensity in the presence of D-aspartic acid was about 600 while the fluorescent intensity in the absence of D-aspartic acid was about 600. The fluorescent intensity in 'the presence of D-cysteine was about 700 while the fluorescent intensity in the absence of D-cysteine was about 600. The fluorescent intensity in the presence of L-cysteine was about 700 while the fluorescent intensity in the absence of L-cysteine was about 600. Based on these result, it was shown that cysteine, in both of L-form and D-form, alleviates the cell damage with a statistical significance. Example 5 [0071] Alleviating effect on ultraviolet irradiation-induced damage in XP cells Methods A human dermal fibroblast derived from a patient having 34 xeroderma pigmentosum (Group A) (XP30S (SVT), hereinafter referred to as "XP cell") which was obtained from Japan Health Science Foundation was employed and cultured by the same method described in Example 3. The pretreatment with 0.1 iM L- or D-glutamic acid, proline and cysteine and the quantification of the cell damage were conducted according to the methods described in Example 3. The UV-A irradiation was conducted using a UV light uniform exposing device UVE-502S+EL-160 (SAN-EI ELECTRIC) by irradiating a UV ray of 320 nm to 400 nm at 1 J/cm 2 from about 20 cm above a culture dish in a state where the lid of the respective culture dish was removed. The UV dose was measured using 1V RADIOMETER UVR-3036/S (Topcon Corporation). [0072] Results of L- and D-glutamic acids Figure 6 shows the results of the experiment investigating the effect of L- or D-glutamic acids on the cell damage in fibroblasts induced by the UV irradiation. The error bars for relevant experimental conditions are the standard deviations of the measured values of the results of the experiments repeated two times under identical conditions. [0073] The fluorescent intensity was about 690 under the condition without UV irradiation in the absence of amino acid (hereinafter referred to as "non-UV irradiating condition") and 35 was about 630 under the condition with UV irradiation in the absence of amino acid (hereinafter referred to as "negative control ") . The fluorescent intensity in the presence of 0.1 iM of L- or D-glutamic acid was about 658 or about 675, respectively. Based on these results, it was shown that both of L- and D-glutamic acid alleviate the UV-A induced cell damage in XP cells. [0074] Results of L- and D-prolines Figure 7 shows the results of the experiment investigating the effect of L- or D-proline on the cell damage in fibroblasts induced by the UV irradiation. The error bars for relevant experimental conditions are the standard deviations of the measured values of the results of the experiments repeated two times under identical conditions. [0075] The fluorescent intensity was about 690 under the non-UV irradiating condition and was about 630 in the negative control. The fluorescent intensity in the presence of 0.1 p.M of L- or D-proline was about 583 or about 664, respectively. Based on these results, it was shown that D-proline alleviates the UV-A induced cell damage in XP cells. [0076] Results of L- and E-cysteines Figure 8 shows the results of the experiment 36 investigating the effect of L- or D-cysteine on the cell damage in fibroblasts induced by the UV irradiation. The error bars for relevant experimental conditions are the standard deviations of the measured values of the results of the experiments repeated two times under identical conditions. [0077] The fluorescent intensity was about 690 under the non-UV irradiating condition and was about 630 in the negative control. The fluorescent intensity in the presence of 0.1 p±M of L- or D-cysteine was about 688 or about 638, respectively.
