Effects and Comparison of Curcumin on Morphology Changes of Chronic Cerebral Hypoperfusion in Young and Aged Rats

Abstract:

To observe the effect of curcumin on the morphology of the hippocampus in young and aged rats with vascular dementia (VD) induced by chronic cerebral hypoperfusion, then further investigate whether the effect of curcumin have any differences in age. Both young and aged Male Sprague-Dawley rats were randomly divided into normal control group, sham-operated group, 2VO group, 2VO+curcumin 50mg/Kg group and 2VO+curcumin 100mg/Kg goup. Permanent occlusion of bilateral common carotid arteries ligation (2VO) method was used to establish chronic cerebral ischemia model. The rats were injected intraperitoneally with curcumin or DMSO once daily for 30d. The pathological changes of CA1 region of the hippocampus were measured by HE staining and Nissl staining. Chronic cerebral ischemia led to pathological changes of young and aged rats, but no significant differences were found between the two ages of rats (t=0.658，P=0.523). Furthermore, curcumin could reduce the pathological injury of CA1 region of the hippocampus in young and aged VD rats, no significant differences were found between the two ages of rats (P=0.384，P=0.380). Curcumin can reduce the brain damage in young and aged VD rats in dose-dependent manner but without age difference. Our study suggests that the pathological injury of the hippocampus might be one of the mechanisms of curcumin’s protection effect of VD rats.
