After opening the chest in the fourth intercostal space, artificial respiration of animals with room air was performed Harvard respirator assistance. Measurement of arterial blood pressure was made in the carotid arteries using a Shtagam pressure transducer, heart rate was determined electronically by continuation of the teeth to an electrocardiogram frames. The maximum rate of pressure increase (dp / dt max) in the left ventricle of the heart was determined using a Konigsberg pressure transducer and a Grasse differentiating amplifier. All parameters were recorded using the direct recording apparatus. To delay clotting, animals were injected intravenously with 10 mg / kg of sodium polyethylene sulfonate dissolved in 20% polydiol. The test substances were administered intravenously to 3-4 dogs. The results of the experiments are given in table. 1. 2. Effect on contraction strength and frequency of isolated guinea pig atria. For the experiment, 4-5 isolated spontaneously atrial guinea pig atria are taken for a substance in the Tyrode solution with the temperature through which the carbogen is bubbled. The voltage was recorded isometrically by means of a tensor with an ohmic sensor using the Grass grapher. Substances were introduced in increasing concentration cumulatively into a bath with experimental organs, the concentration step was 10 min. Due to the poor water solubility in preparing diluted solutions, they proceeded from a 1% solution in poly diol, continuing to dilute them to a Tyrode solution. The resulting final concentrations of polydiol in the 1: 100 organ bath do not have a pharmacological effect. The results of the experiments are given in table. -2 3. Determination of acute toxicity. The acute toxicity of the test substances was determined in mice approximately by intravenous administration for 14 days. Up to 5 belly
