AbstractObjectiveTo study the effect of suanzaoren decoction on sleep phase of insomnia rats. MethodsUnder the conditions of constant temperature, constant humidity, auto-light and electromagnetic shielding, we gave experimental rats suanzaoren decoction at different doses and adopted chronicity electrode embedment technology to trace the EEG of hypodermal layer of freerunning rats , which rececived electric stimulation. Then we analyzed the change of EEG of insomnia rats which were given suanzaoren decoction at different doses. ResultsThe results showed that suanzaoren decoction at low had significant lasting effect on SWS1 (P<0.01) and had no obvious effect on SWS2 (P>0.05),the middle dose of it was able to extend SWS1 and SWS2 obviously (P<0.01) ,and the high dose of it could increase the duration of SWS2 obviously(P<0.05). ConclusionThe suanzaoren decoction can influence the sleep cycle of insomnia rats and the effect are different with the the change of doses.
