摘要
采用噻唑盐 (MTT)比色方法研究在紫外线辐射损伤条件下扇贝多肽对免疫细胞的保护作用 ,并探讨扇贝多肽对胸腺细胞和脾细胞活性的影响。结果表明 ,扇贝多肽具有抗紫外线氧化损伤的作用 ,可减轻或抑制紫外线对胸腺细胞和脾细胞的氧化损伤 ,并且呈剂量依赖性。扇贝多肽在 0 .5%— 1 0 .0 %的浓度范围内 ,其抗氧化能力随浓度的增高而增强 ;在正常条件下可显著增强免疫细胞的活性 ,并且可拮抗雌激素对免疫细胞的抑制作用。提示扇贝多肽不仅具有抗氧化损伤作用 ,而且具有免疫增强作用。
The polypeptides isolated from Chlamys farreri (PCF) by modern bioengineering technique were a water soluble small molecular with biological activity. In this paper the effects of PCF on the proliferative activities of thymocytes and splenocytes and the protective effects of PCF on those immune cells under Ultraviolet (UV) oxidative damage were detected by MTT colorometry. The results showed that PCF could reduce the ultraviolet (UV) damage on the thymocytes and splenocytes with dose dependence. In the 0.5%_10.0% concentration range the higher concentration of PCF the stronger protective effects of it. PCF could also significantly increase the proliferative activities of the thymocytes and splenocytes and could decrease or inhibit the immune suppressive effects of Estradiol on the thymocytes and splenocytes. The results indicate that PCF not only has the effect of antioxidative damage of UV irradiation but also has the effect of increasing immune function.
