摘 要：
为检测巴莲莲子生物碱提取物(alkaloids extracted from Ba lotus seed,AEBLS)对CCl_4诱导的小鼠肝损伤的预防作用,以732交换树脂分离纯化的AEBLS为研究对象,对小鼠灌胃低、高剂量(50、100 mg/(kg·d))AEBLS后注射2 m L/kg CCl_4诱导小鼠发生肝损伤,观察小鼠肝指数、血清指标和肝组织中相关m RNA表达的强度。结果显示,AEBLS可以降低肝损伤小鼠的肝质量和肝指数(P<0.05);AEBLS可以下调肝损伤小鼠血清中的天冬氨酸氨基转移酶、丙氨酸氨基转移酶、碱性磷酸酶、甘油三酯、总胆固醇、尿素氮、一氧化氮、丙二醛水平和上调白蛋白、超氧化物歧化酶(superoxide dismutase,SOD)、过氧化氢酶(catalase,CAT)、谷胱甘肽过氧化物酶(glutathione peroxidase,GSH-Px)水平(P<0.05);同时AEBLS还可以下调肝损伤小鼠血清中白介素-6(interleukin-6,IL?6)、IL?12、肿瘤坏死因子-α(tumor necrosis factor-alpha,TNF-α)和γ-干扰素细胞因子水平(P<0.05)。实时聚合酶链式反应也证实AEBLS能上调肝损伤小鼠肝组织中Mn-SOD、Cu/Zn-SOD、CAT、GSH-Px、核因子κB抑制蛋白α的m RNA表达和下调核因子κB-p65、诱导型一氧化氮合成酶、环氧化酶-2、TNF-α、IL-1β、IL-6的m RNA表达(P<0.05)。由此可见,AEBLS对CCl_4引发的肝损伤有较好的预防作用,且效果接近药物水飞蓟素,具有较好的功能性作用。

摘 要：
The aim of this study was to determine the preventive effects of alkaloids extracted from Ba lotus seeds(AEBLS) on CCl_4-induced hepatic injury in mice.AEBLS was purified using 732 exchange resin and then orally administered to mice.Afterwards,the mice were injected with CCl_4 to induce hepatic injury,and liver index,serum biochemical parameters,and the m RNA expression of related genes in hepatic tissue were evaluated.The results showed that AEBLS could reduce liver weight and liver index in mice with hepatic injury.AEBLS could decrease aspartate aminotransferase(AST),aminotransferase(ALT),alkaline phosphatase(ALP),triglyceride(TG),total cholesterol(TC),urea nitrogen(BUN),nitric oxide(NO) and malondialdehyde(MDA) levels and increase albumin(ALB),superoxide dismutase(SOD),catalase(CAT) and glutathione peroxidase(GSH-Px) levels of the serum of mice with hepatic injury.Meanwhile,it could also increase serum levels of cytokines such as interleukin-6(IL?6),IL?12,tumor necrosis factor-alpha(TNF-α) and interferon-γ?(IFN-γ).RT-PCR results also confirmed that AEBLS could upregulate Mn-SOD,Cu/Zn-SOD,CAT,GSH-Px and IκB-α m RNA expression and downregulate NF-κB-p65,i NOS,COX-2,TNF-α,IL-1β and IL-6 m RNA expression in the liver tissue of mice with hepatic injury.Therefore,AEBLS has a good preventive effect on CCl_4-induced hepatic injury,which is close to that of silymarin.
