RESUMO
<p><b>OBJECTIVE</b>To investigate the effects of the Yifuning soft gelatin capsules(YFN)on estrogen receptor (ER) and nitric oxide (NO) levels in ovariectomized rats.</p><p><b>METHOD</b>Fifty female mature sprague-dawley rats were randomly divided into 5 groups: normal control; model control; diethylstilbestrol tablets (DT); YFN (high dose and low dose). After 4 weeks' treatment, the serum E2 levels were detected by radioimmunoassay. The estrogen receptor (ER) levels of uterus and artery were detected with method of radioligand binding assay of receptor (RBAR). The uterus pathologic changes were investigated with light microscope. NO and NOS levels of the artery and the uterus index were detected too.</p><p><b>RESULT</b>YFN can obviously improve serum E2, increase index and ER of uterus (P < 0.01 or P < 0.05), and ameliorate the uterus' pathologic changes in OVX rats. It also can increase the artery' ER, NO and NOS levels.</p><p><b>CONCLUSION</b>YFN can cure the climacteric syndrome and prevent the cardiovascular disease after post-menopause.</p>

<p><b>OBJECTIVE</b>To study the effects of Yifuning soft capsules on postmenopausal osteoporosis in ovariectomized female rats.</p><p><b>METHOD</b>60 female sprague-dawley rats in 3-month were used, 50 of them were ovariectomized and randomly divided into 5 groups: ovariectomy (OVX), OVX with diethylstilbestrol tables (DT), OVX with YFN (high dose, middle dose and low dose), the others were sham-operated group. Began to give the rats drugs in the fifth week after the operation. After 12 weeks killed the rats. The blood,the uterus and bones were collected to inspect. The content of estrogen (E2) in serum was detected by radioimmunoassay method. The contents of Ca, P, ALP in serum were detected using the automic biochemistry-analyse device. The uterus were weight and the length, width, dry weight and net weight of the shoulder bone were measured. The contents of Ca, Mg, Zn, Mn in the bone were measured using the automic absorption spectrophotometer. The right femer and the third lumbar vertebra were detected for BMD using the dual-energy X-ray absorptiometry scanner and compression test using electronic testing device.</p><p><b>RESULT</b>After using the drugs,the content of E2, Ca in serum, the weight of uterus, the contents of Ca, Mg, Zn, Mn in the bone and the BMD of right femer increased significantly, the content of P, ALP in serum decreased significantly.</p><p><b>CONCLUSION</b>Yifuning soft capsules has a good effect on postmenopausal osteoporosis, which provides evidence for clinical use.</p>

<p><b>OBJECTIVE</b>To develop a new method for the determination of cholesteryl palmitate in Oviductus Ranae.</p><p><b>METHOD</b>A HPLC method was set up, using Zorbax Silica column and cyclohexane-diethyl ether (40:1) as mobile phase with a flow rate of 1.0 mL x min(-1), and the UV detection wavelength was 203 nm.</p><p><b>RESULT</b>The calibration curve was linear over the range of 0.60-8.92 microg (r = 0.9997), the average recovery of the method was 98.4%. RSD 1.8% (n = 6).</p><p><b>CONCLUSION</b>The results showed that method was reliable and accurate.</p>

<p><b>OBJECTIVE</b>To determine the origin of Rana temporaria for quality Oviduetus Ranae in the light of historical documents and modern researches on the classification of Rana temporaria chensinensis.</p><p><b>METHOD</b>Works of Chinese meteria medica of all ages, related historical documents and reports from home and abroad on researches of R. temporaria chensinensis were consulted, sorted out, analyzed and summarized.</p><p><b>RESULT</b>The original Shange recorded in the works of Chinese meteria medica is R. temporaria chensinensis, which is the independent species, not one of species of European forest frogs. R. temporaria chensinensis is divided into 4 subspecies: R. temporaria chensinensis, Lanzhou, Kangding, and Changbaishan. The origin of R. temporaria is Changbaishan subspecies of R. temporaria chensinensis.</p><p><b>CONCLUSION</b>Changbaishan subspecies of R. temporaria chensinensis is determined as the origin for quality Oviduetus Ranae.</p>
