초록

This study was designed to examine the effects of bitter melon (BM) on the plasma blood glucose and cholesterol levels in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats through an injection of streptozotocin (STZ) dissolved in a citrate buffer into the tail vein at a dose of 45 mg/kg of body weight. Sprague-Dawley rats were then fed for four weeks, with the experimental groups receiving a modified diet containing 5% or 10% powder derived from BM. The experimental groups were divided into 4 groups, consisting of the normal control group, STZ-control group and diabetic fed with BM 5% & 10% treated groups. The rats' body weight, blood glucose and cholesterol values were measured along with the hematocrit (Hct) values and aminotransferase activities. Body weight losses were observed in the diabetic groups, whereas the control rats gained weight. There were significant differences in kidney weight between the control group and the diabetic groups. The Hct levels of the diabetic BM-treated group were significantly higher than the STZ-control group. Aspartate aminotransferase activity was lower in the non-diabetic group compared to the diabetic experimental groups. Further, the blood glucose was significantly decreased in the 5% & 10% BM of the diabetic group. There were no significant difference in cholesterol levels among the diabetic groups. These results indicate that the supplementation of bitter melon may have a favorable influence on reducing the blood glucose level in STZ-induced diabetic rats.
