摘 要: | 目的探讨人工合成的钠尿肽-血管钠肽(VNP)对肝纤维化的抑制作用。方法雄性Balb/c小鼠,随机分为玉米油对照组(对照组:腹腔注射玉米油1mL/kg,每周2次,持续12周),肝纤维化模型组(模型组:腹腔注射CCl41mL/kg,每周2次,持续12周,最后6周静脉注射生理盐水1mL/kg.d)和肝纤维化模型+VNP治疗组(VNP治疗组:腹腔注射CCl41mL/kg,每周2次,持续12周,最后6周静脉注射VNP50μg/kg.d)。于末次注射后3d取各组小鼠肝脏标本,观察肝脏病变程度和纤维化水平。体外培养鼠肝星状细胞株(HSC-T6),并加以不同浓度的VNP处理,分别采用[3H]-胸苷和[3H]-脯氨酸掺入的方法检测细胞DNA和胶原的合成水平。结果和对照组比较,模型组出现显著肝脏损伤和胶原沉积,而VNP治疗能明显减轻CCl4诱导的肝脏损伤和胶原沉积;对照组,模型组,VNP治疗组肝脏胶原浓度分别为(43.6±6.3)μg/mg,(93.5±7.2)μg/mg,(62.2±5.1)μg/mg,差异有统计学意义(P<0.05);VNP(10-7mol/L)处理后,HSC-T6的[3H]-胸苷和[3H]-脯氨酸掺入量分别...

Abstract: | Objective To investigate the effects of vasonatrin peptide(VNP),a synthetic novel natriuretic peptide,on liver fibrosis. Methods Male Balb/c mice were randomized into corn oil control group(control group for short,protocol: corn oil 1 mL/kg ip.twice a week for 12 weeks),liver fibrosis group(model group for short,protocol: CCl4 1 mL/kg ip.twice a week for 12 weeks,and saline 1 mL/kg iv.once daily for the last 6 weeks) and hepatic fibrosis+VNP treatment group(VNP treatment group for short,protocol: CCl4 1 mL/... |
