摘要: 目的:在原代培养的新生大鼠心肌细胞上观察低聚葡萄籽原花青素(oligomeric grape seed proanthocyanidins,GSP)对异丙肾上腺素(isoproterenol,Iso)诱导心肌细胞肥大的影响。方法: 采用SD大鼠乳鼠原代心肌细胞培养法,BCA法测定心肌细胞总蛋白含量;流式细胞仪检测心肌细胞内氧自由基(reactive oxygen species,ROS)含量;比色法检测丙二醛(MDA)含量和超氧化物歧化酶(SOD)活性。结果: 1×10-5 mol/L Iso能明显诱导心肌细胞肥大,GSP可剂量依赖性地抑制Iso诱导心肌细胞肥大,抑制细胞内ROS的生成,降低MDA含量、提高SOD活性。结论:GSP对Iso诱导的心肌细胞肥大具有明显的逆转作用, 其机制至少部分与抑制ROS生成、降低氧化应激水平有关。

Abstract: AIM: To investigate the effect of oligomeric grape seed proanthocyanidins (GSP) on neonatal cardiomyocytes hypertrophy induced by isoproterenol (Iso).METHODS: Hypertrophy in cultured neonatal rat cardiac myocytes was induced by Iso. Total protein content was measured by BCA method; reactive oxygen species (ROS) were detected by flow cytometry; colorimetric method was employed to measured MDA content and SOD antivity.RESULTS:1×10-5 mol/L Iso can activate β-AR completely and induce cardiomyocytes hypertrophy markedly. GSP therapy potently inhibited the increase of protein content, ROS generation and MDA content, inhibited the decrease of SOD activity with a dose-dependent manner.CONCLUSION: GSP possess protective effect against Iso induced cardiomyocytes hypertrophy, this may be related to reducing the ROS generation and oxidative stress level, at least in part.
