ADAPTATION OF THE LIPASE-COLIPASE SYSTEM TO DIETARY LIPID-CONTENT IN PIG PANCREATIC TISSUE

This report studies the evolution of some enzymatic activities, i.e. mainly of the lipase-colipase system, in pig pancreatic tissue in response to a change in dietary lipid content. Twenty pigs were divided into two lots of ten each. One lot was fed a diet containing 5 p. 100 of peanut oil and the other a diet containing 25 p. 100 of peanut oil. Lipase and colipase activities in the tissue increased when dietary lipids were augmented. However, colipase increased less (+37.7 p. 100) than lipase (+82.6 p. 100). The choice of a technique for studying the evolution of colipase activity is discussed.
