The six stages involved euthermic state (25℃), prehibernation (10-12℃), after hibernating for a week and a month (2-4℃), and arousing from hibernation for a week and two weeks (10-12℃). From euthermic state to long-term hibernation, lipid peroxidation was showed to increase in brain except the stage of prehibernation.

分别测试了上述各阶段荒漠沙蜥1％脑组织匀浆、0.5％心脏组织匀浆及1％肝脏组织匀浆中：丙二醛及过氧化氢(H_2O_2)的含量，超氧化物岐化酶、过氧化氢酶、谷胱甘肽过氧化物酶的活性，及总抗氧化能力的水平。

RESULTS: Compared with SG, the levels of Cr and BUN and that of MDA in the nephric tissue were significantly higher than those in OG and TM+OG. The levels of these indices in TM+OG were lower than that in OG. The level of GSH in OG and TM+OG was lower than that in SG, but higher in TM+OG than in OG.

结果：腹主动脉缩窄组及替米沙坦+腹主动脉缩窄组血清Cr， BUN含量及肾组织匀浆MDA水平均较假手术组增高，但TM＋OG低于OG；肾组织匀浆GSH水平OG及TM＋OG低于SG，但TM＋OG高于OG。

The method of pH controlled homogenate extraction of carnosic acid in Rosmarinus officinalis was studied, and the optimum technology parameters were found as following: Homogenate once for 4 min with 80% ethanol (adjusted pH=3.0 with HCl) at a ratio of solid to liquid 1:12.

采用pH控制匀浆法从迷迭香枝叶中提取鼠尾草酸，研究了提取过程中不同影响因子对提取效果的影响。确定的匀浆提取优化条件为：以盐酸调节pH=3.0的80%乙醇为提取溶剂，料液比1：12，匀浆4min，匀浆提取1次。

Analysis the changes of each groups mRNA expression of ICAM-1,VCAM-1 and eNOS .Naphthylamide Heavy nitrogen spectrophotography was adopted to detect thecontent of nitric oxide in the blood serum. To try to find out the mechanism of QDTMT prevent and cure function on AS.
