울금(Curcuma longa L.) 섭취가 당뇨성 흰쥐의 크레아티닌 및 간 기능 효소 활성에 미치는 영향

The purpose of this study was to investigate the improvement effect of turmeric (Curcuma longa L.) on the hepatic functional enzyme and catalase activity of streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley (SD) male rats were divided into four groups (n=6), and fed experimental diets containing turmeric meal [basal diet+5% turmeric (BT), basal diet+STZ+5% turmeric (ST)], and control (basal diet, BD), BS groups (basal diet+STZ). Serum concentrations of creatinine and blood urea nitrogen (BUN) were significantly decreased (p<0.05) by 5% turmeric supplementation diet. The activities of akaline phosphatase (ALP), lactate dehydrogenase (LDH), aspartate transaminase (AST), alanine transaminase (ALT), amylase and lipase were decreased in the BD, BT and ST group than BS group. The catalase (CAT) activity was significantly increased (p<0.05) in turmeric supplementation diet (BT, ST group) than diabetic group (BS). Furthermore, the activities of amylase and lipase in the sera of turmeric diet group were significantly decreased (p<0.05). In vivo experiments with diabetic rats showed that ingestion of turmeric supplementation diet were effective in creatinine concentration, and hepatic functional enzyme activities.
