Ohwi, has protecting functions on the cardiovascular system, nervous system, osteoporosis, liver injury, and inflammation in vivo and in vitro. Most of these research studies focused on inhibiting oxidative stress and apoptosis through regulating various bioactivators and signal pathways. Among these, superoxide dismutase(SOD), endothelial nitric oxide synthase(eNOS) and malondialdehyde(MDA), and PI3K/Akt, MAPK, and NF-κB are of great importance. The data cited in this review were mainly obtained from articles listed in PubMed and Elsevier SDOL published from 1959 to 2013, and the search term used was "puerarin".展开更多

文摘目的研究野菊花中萜类和黄酮类化合物对刀豆蛋白A(Con A)诱导的小鼠免疫性肝损伤的保护作用。方法将小鼠随机分成对照组,模型组,野菊花各提取部位(CIF-A,主要含萜类化合物;CIF-B,主要含萜类和黄酮类化合物;CIF-C,主要含黄酮类化合物)高、中、低剂量组,联双酯滴丸阳性对照组。小鼠首日上下午和次日下午各ig给药1次,以后每天给药1次,连续7 d,末次给药后,除对照组外,其他组小鼠尾iv Con A制备小鼠免疫性肝损伤模型。检测小鼠血清中天冬氨酸转氨酶(AST)、丙氨酸转氨酶(ALT)、肿瘤坏死因子-α(TNF-α)、γ干扰素(IFN-γ)的水平;测定肝组织中MDA的量,观察肝脏病理组织学变化。结果与模型组比较,CIF-A、CIF-B均抑制血清中AST、ALT、TNF-α水平的升高;CIF-C抑制AST、ALT、IFN-γ水平的升高;CIF-B可降低肝组织中MDA的量,明显改善肝组织病变,作用优于CIF-A和CIF-C。结论野菊花中萜类和黄酮类化合物对ConA致小鼠免疫性肝损伤均具有一定的保肝作用,CIF-B作用更强。
