ABSTRACT
This article was aimed to study the sedative and hypnotic effects of different eluents of Shuangxiatang (SXT). The effects of SXT water decoction, water eluent, 20%, 70% and 95% alcohol eluent on spontaneous ac-tivity and the sleeping induced by subthreshold dose of pentobarbital sodium were measured. The results showed that the SXT decoction, 20% and 95% alcohol eluent can significantly decrease the number of rearing in mice with the percentage of 78.5%, 78.3% and 62.5%, respectively. SXT water eluent and 70% alcohol eluent can significantly decrease the spontaneous activity of mice (P < 0.01), the number of rearing (P < 0.01) and grooming time (P < 0.05). SXT water decoction can significantly shorten sleep latency (P < 0.05), prolong sleep time (P <0.05), and increase rates of sleeping in mice. SXT water eluent can significantly shorten sleep latency in mice (P< 0.05), increase rates of sleeping in mice. SXT water decoction and water eluent have the sedative and hypnotic effects. And the effects are more than alcohol eluents.
ABSTRACT
This article was aimed to study the therapeutic effect of Chinese medicine Kun-Bao-W an (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 intragas-trically 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 lo-comotor activity mildly but without effect on rearing behavior in ovariectomized mice. Diazepam can markedly pro-long 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 ef-fect 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.
