(-)-Epigallocatechin-3-gallate (EGCG), a main constituent of green tea polyphenols, plays important roles in antioxidative, anti-senescence, anti-tumor, anti-inflammation and bacterail action. In this study, effects of EGCG on the expression of IL-1beta gene and the IL-1beta level at wound sites during cutaneous wound healing were investigated with histological stain, ELISA and RT-PCR technique. The results show that EGCG (50 mg/L) inhibited the expression of IL-1beta gene and reduced the IL-beta level at wound sites at 72 h after cutaneous wound, but not change the expression of IL-1beta gene and the IL-1beta level at early stage (< or =24 h).
(-)-表没食子儿茶素-3-没食子酸酯(EGCG)是绿茶多酚的主要成分,在抗氧化、抗衰老、抗肿瘤、抗炎和抗菌作用中发挥重要作用。本研究采用组织学染色、酶联免疫吸附测定(ELISA)和逆转录-聚合酶链反应(RT-PCR)技术,研究了EGCG对皮肤伤口愈合过程中伤口部位白细胞介素-1β(IL-1β)基因表达和IL-1β水平的影响。结果表明,EGCG(50毫克/升)在皮肤伤口后72小时抑制了伤口部位IL-1β基因的表达并降低了IL-β水平,但在早期(≤24小时)并未改变IL-1β基因的表达和IL-1β水平。
