This study was conducted to examine the effects of a supplemented Chungkukjang diet on oxidative stress and antioxidant nutrients in Streptozotocin (STZ, 45 mg/kg of BW, IP injection)-induced diabetic rats. Diets that contained soybean Chungkukjang powder (SC), Yakkong Chungkukjang powder (YC), and Yakkong Chungkukjang powder with black food added (YCB) were administered to the STZ-induced diabetic rats for seven weeks. The increased lipid peroxide contents of their serum and liver were slightly controlled by providing them three types of Chungkukjang. The retinol level in the serum was 7.5 times higher in the STZ-induced diabetic group after the provision of YC. The total antioxidant capacity (TAC) level in the serum was higher in the STZ-induced diabetic group after the provision of YCB. Also, the retinol and tocopherol levels in the liver of the STZ-induced diabetic rats increased after they were provided YCB, and the decreased reduced glutathione (GSH) /oxidized glutathione (GSSG) level in their liver improved after they were fed a diet that contained YC. Moreover, the decreased anthocyanin level in the liver of the STZ-induced diabetic group improved after the provision of three types of Chungkukjang powder. These findings suggest that the Chungkukjang diet is a valuable food for the management of the health of diabetic patients and for the prevention of diabetic complications.

Objectives : The purpose of this study was to evaluate boiled rice made from unpolished rice, Job`s Tears, and extract from medicinal herbs mixture (HGMCJE) for hypoglycemic effect on STZ-induced diabetic rats. Methods : In the response of glucose tolerance, control and diabetic rats groups was intubated with glucose and HGMCJE. Furthermore, boiled 100% polished rice (P rice), boiled unpolished rice mixed with white rice and Job`s tears (polished rice:unpolished rice:Job`s tears=60:25:15, UPJ-rice), and UPJ rice made from HGMCJE (HUPJ-rice) were intubated to control and diabetic rats groups, respectively. Then, blood glucose concentration, incremental blood glucose, and area under the curve (ΔAUC) were analyzed in every experimental groups, and these data were used to evaluate glycemic response. Results : When glucose and p rice were intubated in control and diabetic rats, blood glucose concentration, incremental blood glucose, and incremental response ΔAUC of diabetic groups were significantly increase than control groups. But administraion of a single dose of extract from medicinal herbs mixture and HUPJ-rice in control and diabetic rats inhibited the remarkable increase the level of postprandial blood and ΔAUC at 60, 90, and 120 min Conclusions : These results indicate that when intubation of glucose and P rice were out of control on postprandial glycemic response in diabetic rats. But postprandial glycemic response was well-modulated by administrating a single oral dose of HGMCJE and HUPJ-rice. Therefore, HGMCJE can be developed as an effective hypoglycemic agent.
