坤宝丸对去卵巢小鼠睡眠的影响

目的：研究中药坤宝丸治疗去卵巢小鼠睡眠障碍的实验疗效。方法：选用健康KM 小鼠60只，按照体重随机均衡的原则分为4 组：假手术组、模型组、地西泮组、坤宝丸组，每组15 只。除假手术组外，其余各组均行双侧去卵巢手术，假手术组不摘除卵巢，只剪掉卵巢周围的小部分脂肪组织。坤宝丸组小鼠于术后28 天灌胃给予坤宝丸1.667 g·kg-1，每天1 次，连续28 天；地西泮组小鼠于测试前1 h 单次灌胃给药，给药剂量为1.25 mg·kg-1。观察坤宝丸对去卵巢小鼠自主活动、戊巴比妥钠诱导的睡眠及子宫系数的影响。结果：与假手术组相比，小鼠摘除双侧卵巢后自主活动次数和站立次数显著增加（P＜0.01），地西泮能够显著降低去卵巢小鼠的自主活动次数（P＜0.01），同时可减少小鼠的站立次数，但无统计学差异；坤宝丸具有减少去卵巢小鼠自主活动的趋势，但是作用不显著，对小鼠的站立次数无明显影响。地西泮能够显著延长戊巴比妥钠诱导的去卵巢小鼠睡眠时间（P＜0.01），坤宝丸能延长戊巴比妥钠诱导的去卵巢小鼠的睡眠时间，缩短睡眠潜伏期，但均无统计学差异。坤宝丸和地西泮对去卵巢小鼠的子宫系数无明显影响。结论：坤宝丸具有改善去势小鼠睡眠障碍的作用，但作用较温和。

Effect of Kun-Bao-Wan on Sleep Disorders in Ovariectomized Mice

This article was aimed to study the therapeutic effect of Chinese medicine Kun -Bao -Wan (KBW) on sleep disorders among ovariectomized mice. A total of 60 female KM of adult mice were randomly divided into four groups, which were the sham-operated group, model group, diazepam group, and KBW group, with 15 rats in each group. Rats in the sham-operated group were only removed small amount of fatty tissue around the ovaries.Bilateral oophorectomy was given on mice in other groups. In the KBW group, 28 days after the operation, KBW was intragastrically administered (1.667 g·kg-1) every day for 28 days. Mice in the diazepam group were intragastrically administered (1.25 g·kg-1) 1 h before testing. The observation was made on effects of KBW on locomotor activity, sleeping time of mice induced by pentobarbital sodium and the organ coefficients of uterus. The results showed that compared with sham-operated group, locomotor activity and rearing behavior increased obviously in the model group (P < 0.01). The diazepam group can significantly reduce locomotor activity in ovariectomized mice(P < 0.01), and decrease the number of rearing behavior mildly with no statistical difference. KBW can reduce locomotor activity mildly but without effect on rearing behavior in ovariectomized mice. Diazepam can markedly prolong the pentobarbital sleep time in ovariectomized mice (P < 0.01). KBW can prolong the pentobarbital sleep time and shorten the process of falling into sleep mildly with no statistical difference. There was no significant effect on organ coefficients of uterus in ovariectomized mice by KBW or diazepam. It was concluded that KBW had mild effect on improving sleep disorders in ovariectomized mice.
