目的:研究天然红心鸭蛋对正常小鼠免疫功能的影响.方法:观察了天然红心鸭蛋对2,4-二硝基氟苯(DNFB)诱导的迟发性超敏反应(DTH)及小鼠血清溶血素含量的影响,并测定小鼠脾脏指数及胸腺指数,以及小鼠脾脏组织切片的病理观察.结果:天然红心鸭蛋能够增强正常小鼠的迟发性超敏反应和血清溶血素含量;脾脏和胸腺指数有一定程度的增加,但影响不显著;并且通过病理切片观察,发现饲喂中(13g/kg·d)、高剂量(19.5g/kg·d)的天然红心鸭蛋组小鼠的脾小体(白髓)的数量也有所增加.结论:适量天然红心鸭蛋一定程度上能调节小鼠的免疫功能.%Objective: To study the effects of natural red yolk of duck's eggs on immunity effects of normal mice. Methods: The immunomodulation activity of natural red yolk of duck's eggs was studied by delayed type hypersensitivity response (DTH)induced by DNFB and serum hemolysin in normal mice. The indexes of thymus gland and spleen were also studied. And the sections of spleens of all mice were observed under the microscope. Conclusions: The natural red yolk of duck's eggs could enhance delayed type hypersensitivity and increase the level of serum hemolysin. From the pathological observation,we knew that the germinal centres of lymphonodus and splenic nodules of the group C and D were indentical. And spleens of the group C's and D's have had well-developed splenic sinusoid.
