Aktywność trypsyny i alfa-amylazy w trzustce świnek morskich. II. Wpływ zarażenia per os i dojelitowo inwazyjnymi jajami Ascaris suum

The guinea pigs were infected orally or intraintestinally (after laparotomy) with 5000 invasive eggs of Ascaris suum. On the 7th day after infection the invasion was controlled by lung's weight, degree of congestion, and number of larvae in the lungs. The activity of amylase was determined according to Fennel method, trypsin to Anson method. The activities of both enzymes in pancreas of orally infected animals (after laparotomy or not) were lower, and relative weight of lungs of these animals was higher than in control animals. In pancreas of guinea pig with invasive material introduced into its, the activities of amylase and trypsin were higher than in control animals, but only the activity of trypsin differed significantly.
