A study on status of the immunity in alloxan diabetic mice and the immunoregulation of insulin / 中国病理生理杂志

ABSTRACT

This paper report the effects of hyperglucosemia and hypoinsulinemia on Immune system of alloxan diabetic mice. The results showed that the weight of thymus and spleen as well as the YAC-1 cell cleaning rate in the organs (lung, liver, blood) of the diabetic mice were significantly lower than that of the control. The proliferation response to Con A(2.5-20?g/ml) and the production of IL-2 of the lymphocytes were inhibi-ted markedly. When the lymphocytes were suspended in the culture medium containiny insulin, the proliferation response and the production of IL-2 increased markedly. These results suggested that the functions of lymphocytes and their natural killer activity were impaired in diabetic mice. Insulin is one of the important immunoregulation hormones and plays an important role in the regulation of immune system.
