据认为维生素E可作为一种抗氧化剂,清除游离根,稳定细胞膜,并对生育力和抗衰老起作用。 1.宿主的抵抗力;最近研究认为,稍超过常用剂量的维生素E可增加对抗原的免疫反应,改善宿主对微生物攻击的抵抗力。使小鸡摄取维生素E增高3～6倍达到维生素 E150～300毫克/公斤,能增加小鸡对实验性大肠杆菌感染的抵抗力。Ayres等曾报告,每天给予大剂量维生素E(800～1,600国际单位),能使硬皮病、盘状红斑狼疮、迟发性皮肤卟啉症、多发性肌炎和某些类型的血管炎缓解。但由于缺乏对照,缺少科学论据。 2.体液免疫:据研究,将中等量维生素E加至动物的饲料中,能提高对菌苗的体液应答。 3.维生素E过量的其他作用:给鼠用含有维生素E 180毫克/公斤的饮食,能使网状内皮系统对血液中
Vitamin E is thought to act as an antioxidant, remove free roots, stabilize cell membranes, and work on fertility and anti-aging. 1. host resistance; recent studies suggest that slightly more than the usual dose of vitamin E can increase the immune response to the antigen, improve the host’s resistance to microbial attacks. Chickens uptake of vitamin E 3 to 6 times to achieve vitamin E50 ~ 300 mg / kg, can increase the resistance of chickens to experimental E. coli infection. Ayres et al. Have reported that daily administration of high doses of vitamin E (800-1,600 IU) can relieve scleroderma, discoid lupus erythematosus, tardive porphyria, polymyositis and certain types of vasculitis . However, due to the lack of control, lack of scientific arguments. 2. Humoral immunity: According to the research, the medium amount of vitamin E added to animal feed, can improve the humoral response to the vaccine. 3. Other effects of vitamin E overdose: to mice with a diet containing 180 mg / kg of vitamin E, can make the reticuloendothelial system on the blood
