RESUMO
Type 2 diabetes mellitus (T2DM) is an age-related disease associated with cerebral inflammation and Alzheimer's disease. Garcinia mangostana pericarp (GMP) possesses antihyperglycemic, antidiabetic and anti-inflammatory effects. The aim of the present study was to evaluate the effect of GMP extract on cerebral inflammation in Wistar rats with T2DM by examining the expression levels of glial nuclear factor-κB (NF-κB), interleukin (IL)-6, tumor necrosis factor-α (TNF-α) and superoxide dismutase (SOD). A total of 36 8-10-week-old male Wistar rats were randomly divided into six groups and provided a standard diet (normal control; C1), high-fat diet (HFD) with 200 g/kg GMP extract BW/day (GMP control; C2), HFD with streptozotocin-nicotinamide (diabetic control; C3), and HFD with 100 (M1), 200 (M2) or 400 g/kg body weight (BW)/day (M3) GMP extract for Wistar rats with diabetes. GMP extract was administered for 8 weeks after induction of T2DM was confirmed. Glial NF-κB activity was assessed by immunohistochemical staining, and by measuring IL-6 levels, TNF-α levels and SOD activity in the serum using ELISA. BW significantly increased following HFD treatment. After 7 weeks, the BW remained significantly higher compared with the normal control and GMP extract-treated groups, but decreased continuously in the T2DM groups. Glial NF-κB immunoreaction in the hippocampal region was significantly higher in the diabetic Wistar rats compared with the normal control Wistar rats, and 200 g/kg BW/day GMP significantly reduced its activity. The T2DM Wistar rats showed significantly higher expression levels of serum IL-6 and TNF-α and lower activity of SOD compared with the normal control Wistar rats. Meanwhile, rats in GMP groups M1, M2 and M3 exhibited significant reductions in the levels of IL-6 and TNF-α expression, and increases in SOD activity. GMP extract treatment effectively reduced hippocampal NF-κB, IL-6 and TNF-α levels and increased antioxidant SOD activity. These results suggest that GMP extract prevents cerebral inflammation in T2DM Wistar rats.
RESUMO
AIM: to obtain profile of food and nutrient intake in Indonesian elderly population and factors associated with energy intake. METHODS: multi-center cross sectional study in 13 hospitals across Indonesia was conducted among 387 elderly who had attended geriatric clinics. Data collected including demographic characteristics, functional status, cognitive status, mental status, nutritional status, food intake, present activities, and data on chronic diseases. Chi square and logistic regression tests were performed to analyze the data. RESULTS: most of subjects (58.4%) were women and had educational background senior high school or higher degree (61.1%). The average of energy intake was 1266.74 (336.51) kilocalories. Calcium and protein intake were below the recommended of dietary allowance. female sex (OR 0.23; 95% CI 0.139-0.390) and osteoporotic subjects (OR 0.48; 95% CI 0.25-0.93) have lower risk for having <80% RDA daily energy intake, while lower educational level (OR 1.96; 95% CI 1.21-3.18) has higher risk for having <80% RDA daily energy intake. CONCLUSION: total energy intake were inadequate in the elderly. Female sex and osteoporotic subjects have lower risk for having <80% RDA daily energy intake, while lower educational level has higher risk for having <80% RDA daily energy intake.
