Study on modified shengmai yin injection for prevention and treatment of brain impairment in endotoxin shock rats

Objective:To examine the effects of modified Shenmai Yin on invigorating vital energy, promoting blood flow, and protection against neural impairment in an endotoxin-induced shock rat model. Methods: Ninety-six SD rats were randomly divided into four groups: sham operation (saline 20 ml/kg), shock model (lipopolysaccharide, LPS, 8 mg/kg), Reformed Shengmai Yin (加味生脉饮 Pulse-activating Decoction) (LPS 8 mg/kg + reformed Shengmai Yin Injection 10 ml/kg), and dexamethasone (LPS 8 mg/kg + dexamethasone 5 mg/kg) groups. Each group was subdivided into 1 h, 2 h, 3 h, and 6 h time points for observation. The carotid artery was separated and connected with a biological functional system to monitor mean arterial pressure (MAP). Brain water levels, malonaldehyde (MDA) content, and superoxide dismutase (SOD) activity were also determined. Results: In the shock model group, MAP was progressively decreased after injection of LPS, brain water and MDA contents were increased, brain SOD activity was decreased, and capillary vessel edema in brain tissue was also observed. All these parameters were improved significantly in both treatment groups, although the effects were more marked with Shengmai Yin than with dexamethasone. Conclusion: Modified Shengmai Yin exhibits strong anti-shock and neuroprotective effects against Endotoxininduced shock.

Antiosteoporotic chemical constituents from Er-Xian Decoction, a traditional Chinese herbal formula

AIM OF THE STUDY: Er Xian Decoction (EXD), a traditional Chinese medicine formula, has long been used for the treatment of osteoporosis and menopausal syndrome in China. The present study was designed to investigate the antiosteoporotic constituents of EXD, and evaluate their antiosteoporotic effects in ovariectomized rats. MATERIALS AND METHODS: Osteoblasts in neonatal calvaria cultures and osteoclasts derived from rat marrow cells were used to bioactivity-guided screen the active constituents. The proliferation of osteoblast was assayed by MTT methods. The activity of ALP and TRAP was measured by p- nitrophenyl sodium phosphate assay. The antiosteoporotic effects of icariin (1), anemarsaponin B II (8) and berberine (6) were verified by using OVX rats model. The bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry using the small animal scan mode. The undecalcified longitudinal proximal tibial metaphysical (PTM) sections were cut and stained for the bone histomorphometric analysis. RESULTS: Bioactivity-guided fractionation has led to the successful isolation of antiosteoporotic constituents, i.e., icariin (1), icariside I (2), baohuoside I (3), mangiferin (4), neomangiferin (5), berberine (6), anemarsaponin B (7), anemarsaponin BII (8), anemarsaponin C (9), anemarrhenasaponin I (10), rubiadin-1-methyl ether (11) and obaculactone (12) from EXD. Further study showed that icariin (1), anemarsaponin BII (8) and berberine (6) increased the BMD in ovariectomized rats, and icariin (1) not only increased the bone formation, but also inhibited bone resorption; anemarsaponin BII (8) mainly increased bone formation and berberine (6) only inhibited the bone resorption in ovariectomized rats. CONCLUSION: Our findings demonstrate that multiple ingredients are responsible for antiosteoporotic activity in traditional Chinese medicine formula Er-Xian decoction.     

实验性脾气虚大鼠血清胃泌素、胃窦G细胞的变化及黄芪建中汤的干预

[目的]探讨脾气虚证大鼠血清胃泌素（gastrin,GAS）、胃窦黏膜胃泌素分泌细胞（G）的变化及黄芪建中汤的干预作用。[方法]以三因素复合的方法复制脾气虚证大鼠模型,随后分别以黄芪建中汤低、中、高剂量对脾气虚大鼠进行复健,在干预后不同时间段,分别检测血清木糖浓度、血清肌酸磷酸激酶活性、血清GAS水平及胃窦G细胞等指标。[结果]随用药时间的延长,各用药组上述指标逐步恢复;中、高剂量组用药21天时,与同期模型组比较,差异有显著性（P〈0.05或P〈0.01）;其中,高剂量组对G细胞数的改善作用,优于中剂量组（P〈0.05）。[结论]脾气虚证胃窦G细胞数量减少,释放GAS减少,血清GAS水平降低;黄芪建中汤对脾气虚大鼠有可靠的治疗作用,中、高剂量均为有效用药浓度,尤以高剂量更为理想。
