| Popis: | Japanese quail of a strain (SUS) susceptible to dietary cholesterol-induced atherosclerosis were fed a diet supplemented with cholesterol (0.5% w/w) for 4, 8 or 12 weeks. Plasma cholesterol increased significantly from 240-1550 mg/dl at 4 weeks and remained at that concentration for 8 and 12 weeks on the same diet. Plasma triglycerides (TGs) increased from 112-384 mg/dl after 4 weeks but showed no significant increases thereafter. Striking eruptive xanthomatous lesions were noticed on the feet of 50% of these birds at 4 weeks, and the percentage of birds affected increased to 85 after 12 weeks on the cholesterol-supplemented diet. This is the first report of xanthomatosis in birds. These birds had also developed atherosclerotic plaques in the aorta and brachiocephalic arteries by 4 weeks. There was no significant correlation between xanthoma scores and plasma cholesterol and TG concentrations at any of the three sampling periods (4, 8 and 12 weeks of cholesterol feeding). There was, however, a significant negative correlation (r = -0.61) between xanthoma scores and atherosclerotic plaque scores at 4 weeks. The correlation became non-significant at later stages of cholesterol exposure. Similarities between mammalian and SUS Japanese quail xanthomatosis may make the SUS quail a useful model for the study of this disorder. |
