摘要
目的:研究山芝麻提取物对肝纤维化大鼠肝组织Ⅰ型胶原(ColⅠ)mRNA和ColⅠ蛋白表达的影响。方法:采用CCl4灌胃复制大鼠肝纤维化模型,6周末用荧光定量PCR法测定山芝麻提取物对大鼠肝组织ColⅠmRNA的相对表达值,用免疫组化法检测ColⅠ蛋白的表达量。结果:山芝麻提取物可显著降低肝纤维化大鼠肝组织ColⅠmRNA和ColⅠ蛋白的表达(P<0.01或P<0.05),且随着药物浓度的增加,其作用逐渐增强,呈现量效反应关系。结论:山芝麻提取物能显著改善肝纤维化大鼠的肝脏组织结构,减轻肝纤维化。其抗肝纤维化的机制可能与抑制ColⅠ有关。
OBJECTIVE:To study the effects of the extract from Helicteres angustifolia on ColⅠmRNA and ColⅠprotein expressions in hepatic tissue of rats with hepatic fibrosis.METHODS:The rat model of hepatic fibrosis was established by intragastric administration with carbon tetrachloride(CCl 4).At the end of the 6 th week,the expression of ColⅠmRNA in hepatic tissue was determined by Fluorescence quantitative PCR(FQ-PCR),and the expression of ColⅠprotein was detected using immunohistochemical stain method.RESULTS:Extract of H.angustifolia could markedly decrease the expressions of ColⅠmRNA and ColⅠprotein(P0.05 or P0.01).As the drug concentration increased,the effects also gradually increased in dose-effect manner.CONCLUSION:Extract of H.angustifolia significantly ameliorates CCl 4 -induced liver fibrosis which is related to the inhibition of the expression of ColⅠ.
