麻黄、炙麻黄及麻杏石甘汤对小鼠戊巴比妥钠睡眠实验的影响

目的通过比较麻黄、炙麻黄及麻杏石甘汤对小鼠戊巴比妥钠睡眠实验的影响,探讨麻黄炮制、组方的意义。方法昆明种雄性小鼠随机分为11组(生理盐水组,盐酸麻黄碱组,麻黄高、中、低剂量,炙麻黄高、中、低剂量组,麻杏石甘汤高、中、低剂量组),连续灌胃给予相应药液6d,末次灌胃后45min各组腹腔注射戊巴比妥钠,观察小鼠睡眠情况,记录睡眠潜伏期和睡眠持续时间。结果与麻黄高、中剂量相比,含等剂量麻黄的麻杏石甘汤睡眠时间均显著延长,P<0.05;与麻黄低剂量相比,含等剂量麻黄的麻杏石甘汤睡眠时间极显著延长,P<0.01;与生理盐水组比较,麻杏石甘汤中、低剂量组的睡眠时间均无显著差异(P>0.05),其余8组的睡眠时间均显著缩短(P<0.05);与麻黄各剂量相比,含等剂量麻黄的麻杏石甘的潜伏期无显著变化,P>0.05;与麻黄各剂量相比,含等剂量麻黄的炙麻黄的潜伏期和睡眠时间均无显著变化,P>0.05。结论在本文实验条件下,以戊巴比妥钠睡眠时间为指标,与等剂量的生麻黄相比,炙麻黄20、10、5g/kg(以生麻黄计)均无降低中枢兴奋作用,而麻杏石甘汤20、10、5g/kg(以生麻黄计)均有显著降低中枢兴奋作用,且有量效负相关关系,其中...

Effect of Herba ephedrae, honey-fried Herba ephedrae and Maxingshigan decoction on pentobabital sodium sleep experiment in mice

Objective To observe the effects of Herba ephedrae, honey-fried Herba ephedrae and Maxingshigan decoction on pentobabital sodium sleep experiment in mice. Methods Male Kunming mice were divided into 11 groups, namely normal saline (NS) group, ephedrine group, 3 Herba ephedrae dose (high, medium, and low) groups, 3 honey-fried Herba ephedrae dose group, and 3 Maxingshigan decoction dose groups. The corresponding drugs were administered intragastrically for 6 consecutive days, and 45 min after the final admin...
