| 摘 要： | 缺乏维生素E(VE)和微量元素硒(Se)都能降低机体的免疫功能。日粮中补充适量的VE或Se使动物对抗原的反应能力加强,高剂量的VE刺激免疫反应增强,高浓度Se则引起机体中毒,抑制免疫功能。 VE和Se有协同作用,活化多种免疫活性细胞,可能主要影响辅助性T细胞。二者共同作用的机制是使生物膜处于还原状态,减少前列腺素的合成,从而加强细胞免疫和体液免疫功能。

EFFECTS OF VITAMIN E (VE) AND TRACE ELEMENT SELENIUM (Se) ON IMMUNICAL FUNCTION OF ORGANISM |
| |
| Abstract: | Both VE and Se deficiency in animal reduced immunical responses of organism to variety antigen. Pharmacological dose VE stimulated animal to enhance immuncical responses, but high Se content in feeds suppressed immunical function.A common focus of action of VE and Se was to make biological membranes in reducing condition, it resulted in decreasing of biosynthesis of prostaglandin. Therefore, production of antibody and function of cell mediated immunity were increased. |
