Objective: Hyperglycemia-stimulated oxidative stress in diabetes mellitus impairs gene expression and activity of endothelial nitric oxide synthase (eNOS). Goat-soy milk kefir has potential to reduce hyperglycemia. This study is to investigate the benefit of kefir from goat and soy milk on eNOS gene expression and nitric oxide (NO) levels. Methods: Twenty five male Wistar rats were grouped as: 1) normal rats; 2) diabetic rats; 3) diabetic rats + goat milk kefir; 4) diabetic rats + combination of goat-soy milk kefir; 5) diabetic rats + soy milk kefir. After kefir intervention for 4 weeks, eNOS gene expression was determined using q-PCR and NO levels was analyzed by ELISA methods. Results: There were significantly differences of the NO levels among group after intervention of kefir for 4 weeks, and the highest NO level was found the diabetic rats with combination of goat-soy milk kefir (p<0.05). However, the eNOS gene expression was found highest in the diabetic rats with soy milk kefir. Conclussion: The combination of goat-soy milk kefir had good effects on expression of eNOS, NO levels and plasma glucose levels in diabetic rats.
