Lipid metabolism in experimental acute pancreatitis

In order to study the changes of lipid metabolism in acute pancreatitis, the following experiments were performed in monogrel dogs. Bile-induced pancreatitis (severe type) and collagenase-induced pancreatitis (mild type) were prepared, and changes of FFA, TG, IRI and IRG were determined for one week. In addition, IVFTT and PHLA were determined at 24th hour, on the 3rd day and 7th day. A rise of FFA was observed during the first 24 hours, which was considered the lypolytic stage. On the 3rd day TG reached the maximal level, while K values in IVFTT and PHLA showed the lowest levels. The above results suggest that the elimination mechanism of TG was impaired on the 3rd day. Changes of FFA, TG, IRI and IRG showed marked differences between the two groups. Therefore it is thought that lipid metabolism in acute pancreatitis is regulated by balance of endogenous pancreatic hormones.
