Abstract:
Vascular Dementia (VaD) is a condition that has a high incidence of disease and affects the quality of life of Thai people. Central nervous system depressive disorder is Parkinson's disease. Based on a recent study that reported the mechanism of free radicals to pathogenesis of Parkinson's disease, and the antioxidant activity of plant extracts. Researchers have hypothesized that Curcumin extract can increase antioxidant activity. It also affects learning and memory. Therefore, this study focus on alcohols extracted from curcumin. Various doses of 100, 200 and 400 mg / kg body weight were fed to male rats of Wistar, weighing 280-320 grams, and then induced by Middle Cerebral Artery Occlusion (MCAO), the free radicals found in brain tissue. Antioxidant activities include superoxide dismutase (SOD), Catalase (CAT) and glutathione peroxidase (GPx) in the brain. Cerebral cortex, striatum, and hippocampus are found in rat. The group received the Curcumin. The activity of the antioxidant enzyme mentioned above increased. MDA decreased in all doses of DEE. When evaluating the effect of Curcumin on protecting the brain. Grouped rats with 200 mg / kg body weight gain. Increased neuronal density Bcl-2 neuronal density increased and Caspase-3 neurons was decreased compared to untreated group. Therefore, this study demonstrates the mechanism of biological action of Curcumin in apoptosis pathway. However, the main mechanism of Curcumin s still to study further mechanism
