ABSTRACT
Objective:To study the effect of BuShen Prescription on metabolism of collagen Ⅰ in ovariectomized rats,which will provide experimental evidence for treating osteoporosis. Methods:50 Ovariectomized SD rats were randomLy divided into 5 groups,including normal control group,model group,positive control (OVX) group,Zuogui Wan group and Yougui Wan group,each group with 10 rats. After 12 weeks' routine feed,normal control group and model group were intragastric administrated with pure water,positive control group was intragastric administrated with conjugated estrogens water-solution,Zuogui Wan group was intragastric administrated with Zuogui Wan decoction,and Yougui Wan group was intragastric administrated with Yougui Wan decoction,then the PINP,DPYD/Cr,NTX/Cr were detected after ovariectomized rats were intragastric administrated with the schedule for 12 weeks. Results :There was statistically significant difference between Zuogui Wan,Yougui Wan group and model group in decreasing the PINP,DPYD/Cr and NTX/Cr (P
ABSTRACT
Objective The changes of thyroid hormone and cyclic nucleotides levels in rats with spleen-kidney deficiency syndrome were observed to evaluate the preventive and therapeutic effect of Yougui Wan(YW) for spleen-kidney deficiency syndrome,and to explore the relationship between the spleen and the kidney at microscopic level.Methods Male SD rats were randomly divided into normal control group,model group,and YW group.Rat models of spleen-kidney deficiency syndrome were established by gavage firstly with rhubarb(4g for each rat) decoction and then with hydrocortisone(25 mg?kg-1?d-1,im).The model group and YW group were treated with distilled water and YW(5.8 g?kg-1?d-1) respectively.The general status of rats was observed,and the plasma cyclic adenosine monophosphate(cAMP) and cyclic guanosine monophosphate(cGMP) levels as well as serum thyroid hormones(T3,T4 and rT3) and thyroid-stimulating hormone(TSH) contents were determined in all rats by radioimmunoassay(RIA).Results Compared with the normal control group,the serum contents of T3,T4,rT3 were decreased significantly(P
