title: Effect of the drug AS2 on the central and peripheral mechanisms of vascular tone regulation.
abstract: The effect of the compound AS2 (N'-benzhydryl, N''-allylpiperazine dihydrochloride) on the central and peripheral mechanisms of vascular tone regulation is studied. Six series of experiments on cats are carried out. The effect of the compound is tested on a model of central-hypertensive reaction, on the spontaneous bioelectrical activity of the renal nerve, on the transmission of excitation to the upper cervical ganglion and the ganglia of the solar plexus. Experiments are made to study its adrenolytic a-d myotropic properties. Cinnarizine is tested as control. The results show that the compound AS2, similar to Cinnarizine, affects the central and peripheral mechanisms of vascular tone regulation. In small doses (1-5 mg/kg) AS2 manifests poor myotropic properties. Administration of the drug in doses of 10-20 mg/kg results in considerable inhibition of the vasomotor centres, brief disturbances in the excitation transmission in the sympathetic ganglia and slight inhibition of adrenergic transmission.
