Effects of Korean Traditional Cheonggukjang Added with Job's Tears on Body Weight Gains and Lipid Metabolism in Rats Fed High-Fat Diet

摘要

This study was performed to investigate the effects of Cheonggukjang added with Job's tears (CAJT) on antiobesity and Hpid profiles on diet-induced obese rats. Male Sprague-Dawley rats were fed high-fat diet only (A, control), and high-fat diet with Cheonggukjang powder 10% (B), CAJT powder 10% (C), Cheonggukjang powder 20% (D), CAJT powder 20% (E) for 5 weeks. Body weight gains were similar in the experimental groups, but PER was significantly lower in the group E than group A (p<0.05), and adiposetissue weights in groups with Cheonggukjang and CAJT powder were similar to those in the group A. The lengths of small intestine were significantly longer in the groups B, C, D, and E than the group A (p<0.05). Hepatic concentrations of total cholesterol(TC) and triglyceride (TG) were similar to each other. Fecal weights were not significantly different among the groups. Fecal TC concentrations were similar in the experimental groups, but fecal TG concentrations were greatly increased in the groups B,D, and E (p<0.05). The serum TC, HDL-C and LDL-C levels varied slightly among the groups, but serum TG levels were decreased in the group D and E than in the group A (p<0.05). The AI and CRF were marginally decreased in the groups B, D, and E than in thegroup A (p<0.05). However, blood glucose levels were not significantly different among the groups. From the findings, it had shown that Job's tears Cheonggukjang could improve lipid profiles.
