초록

This study was designed to evaluate impact of kinds of dietary grain and dietary lipid level on the glucose metabolism and antithrombogenic capacity in obesity induced rats. Total of 80 Sprague-Dawley male rats were raised for one month with control diet containing 50% (w/w) (w/w) of dietary lipids. The rats were blocked into 8 groups and raised for two months with diets containing wel-miled rice, brown rice, black rice, or glut-inous barley powder and 8 or 20% (w/w) of dietary lipids. The contents of total dietary fiber in experimental grains were in following order; glutinous barley > black rice > brown rice > wel-milled rice. Wekly fod intake were lower in glutinous barley group among all experimental groups. Body weight gain was high in high level of fat groups (20% w/w) (8% w/w). Plasma glucose concentration was not diferent significantly in each groups. But brown rice group was a little lower than others. Plasma insulin concentration was lower in black rice and glutinous barley group than rice group. Plasma glucagon concentration did not difer significantly among all experi-mental groups. Hexokinase activities in skeletal muscle are diferent significantly acording to level of dietary fat and grain variety factors. Brown rice group was significantly highest among all experimental groups in hexokinase activity. Plasma TXB2groups. Plasma 6-keto-PGF1α concentrations in glutinous barley group was higher as compared to others. In conclusion brown rice has a little lowering efect glucose concentration. Black rice and glutinous barley intakes enhance antithrombo-genic capacity. It is sugested that the intakes of mixed gains are recommend. (Korean J Nutrition 38(8): 613 ~ 625, 2005)
