目的研究景天三七药材不同提取部位对小鼠胃粘膜的保护作用。方法用不极性溶剂提取得到不同提取部位: 水提醇沉部位的低、高剂量(干膏0. 32, 0. 96 g·kg~(-1)),水提取部位的低、高剂量组(干膏0. 61, 1. 83 g·kg~(-1)),醇提部位的低、高剂量(干膏0. 14, 0. 42 g·kg~(-1)),石油醚提取部位的低、高剂量(干膏0. 05, 0. 15 g·kg~(-1))。连续灌胃给药10 d 后,经腹腔注射消炎痛,建立胃溃疡小鼠模型,肉眼观察小鼠胃部溃疡情况进行评分,并进行组织病理学检查。结果肉眼观察和病理学检查显示,水提醇沉部位的低、高剂量(干膏0. 32, 0. 96 g·kg~(-1)),水提部位高剂量(干膏1. 83 g·kg~(-1))、石油醚部位...

In the fairy rings formed Tricholoma Mongolicum Imai.in steppe of NeiMongol region,distribution of different groups of soil microorganism in the zones has significant difference in the number,number of bacteria in the soil sample of scorched zone (growth mushroom) has a strong increase to contrast with lush zone,inside,centre and outside of the fairy rings.Both the aerophile bacteria and spore forming bacteria increase in the scorched zone.The results shows that there are close relation between the growth of bacteria and forming of the mushroom.The number of fungi,actinomyces and decomposing c...
