摘要
为了探讨强痛宁麻醉镇痛作用与中枢脑区Na^+-K^+-ATP酶的相关性,试验选取24只纯种SD大鼠随机分成对照组、诱导组、麻醉组和催醒组,于各时间点冰上采集大鼠各脑区,采用比色法测定Na^+-K^+-ATP酶活性。结果表明:药物作用后诱导期及麻醉期大鼠大脑皮质、小脑内Na^+-K^+-ATP酶活性显著低于对照组(P<0.01),海马、丘脑及脑干区Na^+-K^+-ATP酶活性与对照组比较极显著降低(P<0.01),催醒期各脑区Na^+-K^+-ATP酶活性恢复到麻醉前水平。说明强痛宁可引起大鼠各脑区Na^+-K^+-ATP酶活性降低,阻碍神经细胞对痛觉刺激信息的传导,产生了麻醉镇痛作用。
To explore the correlation between the narcotic analgesic effects of Qiangtongning and Na ^＋ - K^ ＋ - ATPase in central brain regions, 24 pure - bred SD rats were randomly divided into a control group, an induction group, an anesthesia group and a wake group. Brain samples were collected from the rats on the ice at different time points. The activity of Na ^＋ - K ^＋ - ATPase in the samples was determined by using colorimetric assay. The results showed that the activity of Na^ ＋ - K^＋ - ATPase in cerebral cortex and cerebellum was extremely significantly lower （ P 〈 0.01 ） than that of the control group during the induction and anesthesia after administration ; the activity of Na^＋ - K ^＋ - ATPase in hippocampus, thalamus and brain stem was extremely significantly decreased （P 〈0.01 ） compared with that of the control group; the activity / of Na ^＋ - K^ ＋ - ATPasc in different brain regions were recovered to the level before anesthesia in the waking period. The results indicate that Qiangtongning can cause the activity of Na ^＋ - K ^＋ - ATPase in different brain regions to reduce in rats and hinders the nerve cells to transmit pain stimulus information, resulting in a narcotic analgesic effect.
