Ethambutol is a first-line drug used for antituberculosis therapy. It is often used in combination with isoniazid, rifampin, pyrazinamide, and streptomycin. The action of EMB in antituberculosis mechanism is the destruction of cell wall of tubercle bacilli via binding the target molecule -- arabinosyl transferases. These enzymes are involved in the polymerization of the cell wall arabinan. Inhibition of arabinan synthesis by EMB results in the accumulation of mycolic acids, leading to cell death.The EMB-resistance of MTB is involved with the mutation of emb operon or the over expression of emb operon.

乙胺丁醇是和异烟肼、利福平、链霉素、吡嗪酰胺联合治疗结核病的一线抗结核药物，EMB对结核分枝杆菌的作用机制与分枝杆菌胞壁结构破坏有关，主要作用于靶分子阿拉伯糖基转移酶，抑制了阿拉伯糖基聚合入阿拉伯半乳聚糖，从而影响细胞壁分枝菌酸-阿拉伯半乳聚糖-肽聚糖复合物的形成，导致菌细胞的死亡。

在相同浓度下，去氧胆酸钠的酶抑制作用比杆菌肽弱，但比屈来赛多强。

In order to express the recombinant peptide of both gp52 and pp150 Oterminal peptides from human cytomegalovirus in the Pichia pastoris, the recombinant plasmids were transformed into Pichia pastor is by electroporation after linearised respectively by Sac I or Bg1II, the transformants were screened in MD plates without histidine.

为了在巴斯德毕赤酵母中表达人巨细胞病毒gp52C末端和pp150C末端串联片段的嵌合肽，将构建好的hCMVp-pPIC9K重组质粒分别经Sac Ⅰ和Bg1 Ⅱ酶切，电打孔法导入毕赤酵母GS115后，在缺组氨酸的MD板上筛选出转化子。

Experimental Center of National Level One, Hubei Traditional Chinese Medica l College, Wuhan 430061）Abstract To investigate the protective effects of Jiaweisinisa n on acute liver injury induced by intraperitoneal injection of D-ga lac-tosamise, serum superoxide dismutase, malondialdehyde , glutathioe contents were measured. The pathological changes of liver wer e observed simultaneously. The results showed that JWSNS could decrease serum MD A content, but increase serum SOD and GSH activities in acute liver injury induc ed by D-GalN. It was also found that JWSNS could alleviate the degeneration and necrosis of the hypatocytes.

为研讨加味四逆散防治肝损伤的作用机理，通过动物试验，先用加味四逆散预防给药，再采用D-氨基半乳糖造成大鼠急性肝损伤模型，然后检测大鼠血清超氧化物岐化酶、丙二醛、还原型谷胱甘肽水平，同步观察该方对急性肝损伤大鼠体内脂质过氧化反应及肝脏病理改变的影响，结果表明该方可明显升高大鼠血清SOD、GSH水平，降低MDA水平，肝脏病理学检查亦表明该方使肝细胞变性坏死程度减轻。
