The influence of central cholinolytics and adrenoblocking drugs on the hemolysis of rat erythrocytes in the hypoosmotic buffer was studied in vitro. At pH 7.4 in a concentration of 10(-4) M central cholinolytics ethyl-dipracil, diphacil, pediphen, tropacin, and beta-adrenoblocking agent propranolol protected the erythrocytes from hemolysis most intensively. The central M-cholinlytics amizyl, glypin, and alpha-adrenoblocking agents purroxan, sympatholytin, phentolamin were less active. The antihemolytic effect of drugs reached the maximum in the course of 30 minutes, and was maintained for several hours. The protection of erythrocytes from hemolysis by drugs containing tertiary nitrogen was greater. Prevention of the hypoosmotic hemolysis pointed to the stabilization of the erythrocyte membrane by the preparations examined. In the mechanism of action of the central N-cholinolytics and beta-adrenoblocking drugs it is necessary to consider the possibility of stabilization of the membrane formations containing no synaptic contacts.
