Effects of complete Freund's adjuvant-induced thymocyte apoptosis on NOD mice with type 1 diabetes / 解放军医学杂志

ABSTRACT

Objective To investigate the preventive effect of complete Freund's adjuvant induced thymocyte apoptosis on NOD mice with type 1 diabetes.Methods Forty-two female NOD mice of 3 weeks old were randomly divided into complete Freund's adjuvant group(CFA)and phosphate buffer saline group(PBS)(21 each).Animals of CFA group received injection of 50?l CFA at hind foot-pad,and those in PBS group received 50?l PBS at the same location.Five mice of each group were sacrificed at the 6th and 12th week,respectively,and the remainders of each group were sacrificed at the 30th week for the examination of insular ? cell apoptosis,thymocytes apoptosis,insulitis severity and diabetes incidence.Results Both the insulitis severity score and the ? cell apoptosis declined(P
