PG - 120-6 AB - Diabetes mellitus is a significant risk factor for cardiovascular diseases, and low-grade systemic inflammation, mediated by oxidative stress, may play a central role. Caloric restriction (CR) has been reported to be effective in reducing oxidative stress during diabetes and moderating the expression of some markers of inflammation that are up-regulated during aging. Forty male Wistar rats were randomly divided into four groups: nondiabetic feeding ad libitum and under CR, and diabetic feeding ad libitum and under CR. The animals were subjected to 30% CR and ad libitum feeding for 9 weeks before the induction of diabetes by intraperitoneal injection with 35 mg/kg body weight streptozotocin. The inflammatory cytokines [interleukin (IL)-1beta, IL-4 and IL-6] and tumor necrosis factor alpha up-regulated in diabetes were found to be significantly depressed by CR, whereas the antiinflammatory mediators, haptoglobin and IL-10 levels, were increased. These results indicated that CR could prevent diabetic complications through suppression of inflammatory responses.
