율무청국장이 고지방식이를 급여한 흰쥐의 체중변화 및 지질대사에 미치는 영향

Abstract

This study was performed to investigate the effects of Cheonggukjang added with Job's tears (CAJT) on antiobesity and lipid 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 FER was significantly lower in the group E than group A (p＜0.05), and adipose tissue 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 the group 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.
