Abstract/OtherAbstract:
This study was performed to delineate the combined effects of a low-fat diet and chronic ethanol ingestion on collagen metabolism in rat pancreas. Rats fed a very low-fat diet (5% of total calories as lipid) for 12 weeks developed malnutrition as judged by weight loss (-33% of the initial body weight) and low serum albumin and amylase levels. The pancreas of malnourished rats showed increased collagenase activity with respect to animals fed a 35% lipid diet (p < 0.05). Hydroxyproline content was higher in the pancreas of malnourished rats and collagenase activity correlated well with hydroxyproline content (r = 0.57, p = 0.0013). Ethanol feeding for 12 weeks, regardless of the nutritional state of the rats, did not change the synthesis and degradation rates of collagen in the pancreas. The present study suggests that malnutrition may have profound effects on collagen metabolism.
