Abstract:
Zinc deficient model was made by feeding zinc deficient rations to mice. Their general appearance, body weight, organ body weight ratio, macroph-age (M?) and intestinal mucosal epithelium were observed. Rations intake of these Zn deficient mice decreased 2 weeks later. There was prominent difference in body weight between the Zn deficient (n = 24) and the control group (n =11), and the difference was more prominent 4 weeks later. The mortality of the mice in Zn dificient group was 29.17% while all of the control mice were alive. Weight of liver, spleen, kidney, adrenal glands thymus and the oryan body weight ratio of the thymus of Zn deficient mice decreased markedly. Under the scanning electron microscope, the following variance were shown. The superficial structure of M? in the Zn deficient group tended to be simplified, the pseudopodium tended to be decreased and short. The ratio of activated cells to total M?cells decreased to 56.4% while that of the control group was 81.9% (P
