摘要: 目的:研究硒(Se)及维生素E(VE)对去甲肾上腺素(NE)处理的心肌成纤维细胞(CFbs)Ⅰ型胶原合成的影响。方法:酶消化法获得Wistar大鼠乳鼠CFbs,与NE、Se和VE作用一定时间后,测定上清中羟脯氨酸(HYP)和Ⅰ型胶原含量。结果:Se、VE及Se+VE组培养液中HYP含量分别为(64.88±1.25)、(47.60±1.59)和(41.34±1.73)mg·L-1 prot,明显低于NE组[(68.27±1.89)mg·L-1 prot](P<0.05),Ⅰ型胶原含量分别为(0.67±0.05)、(0.40±0.03)和 0.39±0.04,与NE组(0.90±0.15)比较,差异有显著性(P<0.05)。结论:Se和VE单独应用可抑制CFbs Ⅰ型胶原的合成,二者联合应用具有协同作用。   

Abstract: Objective To investigate the effect of selenium (Se) and vitamin E (VE) on collagen Ⅰ synthesis in cultured cardiac fibroblasts (CFbs) treated with norepinephrine (NE). Methods CFbs were obtained by the method of enzymatic digestion culture. Cells and culture medium were collected after 48 h,then the hydroxyproline (HYP) and collagen Ⅰ content as well as the expression of α1 [Ⅰ] col1agen mRNA were examined. Results The contents of HYP in Se, VE and Se+VE groups were (64.88±1.25),(47.60±1.59) and (41.34±1.73) mg·L-1 prot,respectively,all of them were lower than that in NE group(P<005), which was ( 68.27±1.89) mg·L-1 prot.The contents of collagen Ⅰ in Se, VE and Se+V E groups were (0.67±0.05),(0.40±0.03),(0.39±0.04), respectively; they were lower than that in NE group (0.90±0.15)(P<0.05). Conclusion Se and VE can inhibit the synthesis, secretion of HYP and type Ⅰ collagen,and they can play in synergetic effect when they are used together.
