Though the primary stimulator of 1H is not clear, it is related to physical, cell and body fluid IH is a chronic process involving multiple faction injury and blood flowing abnormal are revamped as the main reason, the proliferation level depend on the length and width of the injure of vessel large amount research illustrate injury cause many growth factor infolded in IH, for example: template derived growth factor, fibroblast growth factor, transmission growth factor , endothelin (ET-1) et al, some early responsive gene such as c-fos、c-jun c-myc also take part in SMC proliferation after vessel injury.

虽然IH的确切起始刺激因子并未阐明，但已知与物理、细胞和体液因子有关。IH是一个多因素参与的慢性过程，损伤和血液动力学异常一真被认为是IH的主要因素。内膜增殖的程度有赖于血管损伤的长度和深度。近年来大量的实验研究结果表明，损伤等刺激引起的众多的生长因子样物质在IH中起关键作用。如血小板源性生长因子、碱性纤维母细胞生长因子、转化生长因子β、内皮素-1（ET-1）等诸如C-fos、C-jun、C-myc等早期应答基因也参与了血管损伤后SMC的增殖。

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。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.
