As intake of Fe increased, serum total cholesterol increased from 2\u00b70 mmol\/l in controls to 5\u00b72 mmol\/l at the highest level of Fe. Also, the total serum phospholipid fatty acids increased from 609 mg\/dl in controls to 1292 mg\/l at the highest level of Fe. Except for the highest dose of Fe, the ratio of saturated to unsaturated phospholipid fatty acids increased from 1\u00b72 to 1\u00b77. The serum total free fatty acid levels remained constant among all groups with a range from 162 to 228 mg\/l, while a ratio of 0\u00b76 to 0\u00b78 for saturated to unsaturated fatty acids was maintained. A dose-related increase in liver non-haem Fe from 18 to 3500 \u03bcg\/g correlated with increases in lipid peroxidation (<jats:italic>r<\/jats:italic>0\u00b787), measured by the lipid-conjugated diene assay. Oxidative changes in the liver may have resulted in alterations in sterol synthesis, leading to increased serum cholesterol levels with increases in serum phospholipids and changes in the ratios of their saturated to unsaturated fatty acids. Animals with heart damage showed myocardial degeneration and cardiomyopathy with haemosiderin in interstitial macrophages or myocardial fibres and, when these were coupled with the findings of increased non-haem Fe in the heart and lipid peroxidation in the liver, suggested that oxidative stress is involved in the pathogenesis of the lesions.<\/jats:p>","DOI":"10.1079\/bjn2001439","type":"journal-article","created":{"date-parts":[[2008,5,15]],"date-time":"2008-05-15T16:15:55Z","timestamp":1210868155000},"page":"587-592","source":"Crossref","is-referenced-by-count":11,"title":["Effect
