[The anti-ischemic effects of 3-hydroxypyridine derivatives in cerebrovascular pathology]. / Protivoishemicheskie éffekty proizvodnykh 3-oksipiridina pri tserebrovaskuliarnoi patologii.

ABSTRACT

The effect of the antioxidant mexidol and two new derivatives of 3-oxypyridine, namely LBK-10 and LBK-39 on the circulation of blood and metabolism of the brain in the postischemic period was studied in acute experiments on narcotized cats under conditions of autohemoperfusion of the cerebral vessels with a stable volume of blood. Therapeutic injection of mexidol and LBK in a dose of 20 mg/kg inhibited the development of the no-flow phenomenon and restored the ischemia damaged metabolism in the brain tissues. LBK-10 reduced the lactate content in the blood flowing from the brain and contributed to constriction of the cerebral vessels.
