-
摘要: 目的 观察当归补血汤及拆方对免疫性肝损伤大鼠的肝功能、肝纤维化的影响。方法 采用猪血清腹腔给药方法,造成免疫性肝损伤模型,检测大鼠血清中丙氨酸转氨酶(ALT)、天门冬氨酸转氨酶(AST)、超氧化物歧化酶(SOD)、脂质过氧化物丙二醛(MDA)、透明质酸(HA)、IV型胶原、III型前胶原。结果 黄芪/当归5∶1组可明显降低猪血清所致免疫性肝损伤大鼠的血清AST、ALT含量;黄芪组、当归组及黄芪当归不同配比组均能升高SOD水平,降低MDA的含量;黄芪组能明显降低HA、IV型胶原;当归补血汤5∶1组能明显降低III型前胶原水平,且优于10∶1组。结论 当归补血汤对免疫性大鼠肝损伤模型具有一定保护作用,其作用机制可能与降低、抑制脂质过氧化反应以及抗自由基损伤有关。Abstract: OBJECTIVE To observe effects of Danggui Buxue Decoction and the composition on liver function and liver fibrosis in rats with immunological liver injury. METHODS The immunological liver injury models were established with intraperitoneal administration of pig serum, whose alanine aminotransferase (ALT), aspartate aminotransferase(AST), superoxide dismutase(SOD), lipid peroxide malondialdehyde (MDA), Hyaluronic acid (HA), IV collagen and III procollagen were detected. RESULTS The group with ratio of Astragalus root to Chinese angelica 5:1 significantly decreased AST and ALT levels; Astragalus root group, Chinese angelica group and groups with different ratios of Astragalus root to Chinese angelica increased SOD levels and decreased MDA content; Astragalus root group obviously reduced HA and type-IV collagen; Danggui Buxue Decoction group with the ratio 5:1 significantly reduced type-III procollagen levels, superior to that in group with ratio10:1. CONCLUSION Danggui Buxue Decoction makes a certain effect on rats with immunological liver injury, whose mechanism may be related to reduction and inhibition of lipid peroxidation and anti-free radical damage.
