Studies showed that 15-day restriction of motor activity inhibits the reuptake of GABA by sections of the rat brain cortex and hypothalamus. In prolonged intraperitoneal injection of 10 mg/kg cinnarizine in hyperkinesia, further inhibition of this process in hypothalamic sections is encountered on the 15th days. Flunarizin (1 mg/kg) administered in a like manner has no significant effect on GABA reuptake. A course of GABA injections in a dose of 5 mg/kg improves in rats with restricted motor activity the local blood flow in the frontal lobe of the brain.
研究表明,对大鼠运动活动进行15天的限制会抑制大鼠大脑皮层和下丘脑切片对γ-氨基丁酸(GABA)的再摄取。在运动亢进状态下,长期腹腔注射10mg/kg桂利嗪,在第15天时会使下丘脑切片中该过程受到进一步抑制。以同样方式给予氟桂利嗪(1mg/kg)对GABA再摄取无显著影响。对运动活动受限的大鼠注射5mg/kg剂量的GABA疗程可改善其大脑额叶的局部血流。
