Effects of Chaishao Ruzeng Capsule on Neurotransmitter and Gastrointestinal Hormone in Rats with Liver Depression and Qi Stagnation Mammary Hyperplasia
Objective To observe the improvement effect and mechanism of Chaishao Ruzeng capsule on mammary gland hyperplasia model rats with liver stagnation and qi stagnation.Methods The rats were injected with estradiol benzoate and unpredictable stress stimulation to replicate the model of mammary hyperplasia with liver depression and qi stagnation.Model rats were given high,medium and low doses of Chaishao Ruzeng Capsule(1.2,0.6,0.3 g·kg-1).28 consecutive days.The general state and behavioral indexes,nipple diameter and height,and pathomorphological changes of breast tissue were observed,and serum P,LH,FSH,E2,5-HT,NE,DA,MTL,VIP,SP were measured.Results Compared with the blank control group,the rats in the model group were depilated,lassitude,unresponsive,irritability,less spontaneous activity,lower sucrose preference(P<0.01),and lower body weight;The nipple diameter and height both increased(P<0.01);The degree of hyperplasia of breast lobule increased(P<0.01).The contents of E2,LH,5-TH,NE,DA,MTL and SP in serum increased,while the contents of P and VIP decreased(P<0.01).Compared with the model group,the symptoms of depilation,lassitude,unresponsiveness and irritability were significantly improved in the various dosage groups of Chaishao Ruzeng capsule,the number of autonomous activities and sucrose preference increased(P<0.05 or P<0.01).The nipple diameter and height both decreased(P<0.05 or P<0.01);The contents of P,FSH and VIP in serum were significantly increased,and the contents of E2,LH,5-TH,NE,DA,MTL and SP were significantly decreased(P<0.05 or P<0.01).Conclusions Chaishao Ruzeng capsule can alleviate sexual hormone disorder,regulate the level of neurotransmitters,improve gastrointestinal hormone abnormalities,improve liver-qi stagnation symptoms,play a role in inhibiting mammary gland hyperplasia.
