Changes in the microcirculatory bed of the rat brain cortex during motor activity and hypodynamia under the action of piracetam, GABA and bicuculline were studied. The possibility of the development of compensatory processes due to the cerebral blood flow increase under the influence of GABA agonists at a disturbance of the cerebral hemodynamics in combination with increased locomotor activity and also due to the improvement of the microcirculation at early stages of hypodynamia induced by administration of GABA agonists opens up new perspectives in the use of GABA-positive drugs.
研究了在运动活动和动力不足状态下,吡拉西坦、γ-氨基丁酸(GABA)和荷包牡丹碱作用下大鼠大脑皮质微循环床的变化。在脑血流动力学紊乱且运动活动增加的情况下,GABA激动剂可使脑血流量增加,从而引发代偿过程;同时,在给予GABA激动剂诱导的动力不足早期阶段,微循环得到改善,这为使用GABA阳性药物开辟了新的前景。
