title: [Effect of armin on the microcirculation of the cerebral cortex of white rats].
abstract: Experiments on white male Wistar rats with the use of the cinetelevision technique have shown that armine in a single LD50 provokes a 85-100% increase in the blood flow rate in the microvessels and a 45-50% elevation of the diameter of the pial arterioles. Administration of the drug in a dose of 1/2 of the LD50 brings about a 90% increase in the blood flow rate, whereas the diameter of the arterioles declines by 25%. The LD50 of armine lowers the cholinesterase activity in the brain and blood by 50-60%, while 1/2 of the drug LD50 by 20-30%.
