The Effect of Retinoic Acid on Ito Cell Proliferation and Content of Nucleic Acid

摘要

摘要: 为探讨维甲酸（Retinoicacid ,RA）对贮脂细胞的增殖和DNA、RNA含量影响 ,筛选抗肝纤维化有效药物。用原代培养的大鼠贮脂细胞 ,采用3H -TdR掺入实验 ,图象分析技术检测贮脂细胞增殖活性和DNA、RNA含量。结果维甲酸在 10 〔5～ 10 -4 mol/L可抑制贮脂细胞3H -TdR掺入 ;在 10 -4 mol/L可降低原代培养贮脂细胞的DNA、RNA含量 ,与对照组比较有显著性差异（P <0 .0 5 ）。表明维甲酸可抑制贮脂细胞3H -TdR掺入及降低原代培养贮脂细胞的DNA、RNA含量。RA可望成为有效的抗纤维化药物。

Abstract: To clarify the mechanism of Retinoic acid (RA) against hepatofibrosis. 3H-TdR incorporationo test and Microspectrophotometer were used to analyse the proliferation of Ito cells and the DNA/RNA contents of Ito cells.The 3H-TdR incorporation in primary cultured Ito cells was suppressed by RA at 10 〔5 -1- -3 mol/L to the extent 50%-60%;DNA/RNA contents in primary cultured Ito cells treated with RA at 10 -4 mol/L were reduced as compared with the control.This suggests that vit A can inhibit Ito cell proliferation and prevent the transformation of Ito cells to my ofibroblasts.RA is expected to be an effective antihepatofibrotic agent in clinical practice.
