Benefits of Fermented Milk in Rats Fed by Hypercholesterolemic Diet (II)
초록
This study was performed to investigate the term effect of fermented milk in drink on rats fed by cholesterol diet. 150 to 5-week-old male rates of Sprague-Dawley strain weer divided into six groups according to diet and content of fermented milk in drink. The first group served as normal control group fed by synthetic pellets of standard diet. The second , cholesterol control group, was treated with standard diet containing 1% of cholesterol and 500000IU/100g of vitamin D2. The other four groups. fermented milk groups, FM-25,FM-50 , FM 75 and FM-100 were treated with the cholesterol and vitamin D2 diet and supplied with 25%, 50%, 75%, 100% of fermented milk in drink , respectively. The animals were sacrificed for analysis in 3, 6, 9 and 12 months. Weight gain, diet intake , and drink consumption were significantly different among groups. Fermented milk reduced serum cholesterol to a significant effect (p<0.05) and significantly increased the ratio of high density lipprotein cholesterol to total cholesterol(p<0.05). Serum triglycerides were reduced to a smaller and less significant effect in fermented milk group. The aorta and liver of fermented milk showed slighter medial calcification and necrosis and milder fat degeneration than did the cholesterol control group. Supplementation of fermented milk may have a helpful effect on hypercholesteremia and atherosclerosis.
