Treatment of rotaviral gastroenteritis with Qiwei Baizhu powder

AIM To observe the effects of Qiwei Baizhu Powder ( QWBZP) on rotaviral gastroenteritis in children and in animal models.``METHODS Enrolled patients were divided into two groups, and one group was treated with oral rehydration solution(ORS) and the other treated with oral liquid of QWBZP. Neonate mice were orally infected with 50 μLrotavirus suspension (4 × l0s PFU/mL) and treated with ORS or oral liquid of QWBZP, respectively.``RESULTS Eighty-three cases of rotaviral gastroenteritis treated with QWBZP revealed a better efficacy than that treated with ORS (x2 - 10.8T, P<0.05). The contents of sodium and glucose as well as number of patients with positive human rotavirus antigen in stool in QWBZP group were all less than that in ORS group. In animal models,QWBZP was found effective in treating rotavirus gastroenteritis in neonate NIH mice, as compared with control groups. In QWBZP group, the mortality of infected mice was decreased by 73.3%, the body weight of infected mice was increased, the contents of sodium and glucose as well as number of mice with positive rotavirus antigen in feces were significantly reduced, and the pathological changes such as damage of small intestinal mucosa and villi were also obviously alleviated.``CONCLUSION QWBZP has effects on improving the absorptive function of small intestine, shortening the duration of diarrhea and rotavirus shedding from stool and alleviating the pathological changes of small intestine induced by rotavirus.

胃舒散对四氯化碳性肝损伤小鼠的影响

【目的】 观察胃舒散对四氯化碳(CCl_4)所致小鼠急性肝损伤的影响。【方法】 昆明种小鼠50只,随机分为5组,分别为正常对照组、模型组、联苯双酯组(150 mg/kg)和胃舒散高、低剂量组(4.0g/kg、2.5g/kg),各给药组分别灌胃给药,连续7 d,第8天除正常组外,其他各组小鼠经腹腔注射体积分数为0.5％CCl_4花生油溶液(10 mL/kg),16 h后测定小鼠肝质量、血清丙氨酸氨基转移酶(ALT)值、肝组织丙二醛(MDA)值及坏死灶数目。【结果】 CCl_4急性肝损伤小鼠肝质量增加(与正常组比较P<0.05),血清ALT升高(与正常组比较P<0.01),肝组织MDA水平升高(与正常组比较P<0.01),肝组织坏死灶显著增加;与模型组比较,胃舒散能降低血清ALT和肝组织MDA水平(均P<0.05),并能减少肝组织坏死病灶(P<0.05或P<0.01),但对肝质量增加无明显影响。【结论】 胃舒散对小鼠CCl_4急性肝损伤有一定程度的保护作用。
