Altywność trypsyny i alfa-amylazy w trzustce świnek morskich. I. Wpływ wielkości dawki zarażeniowej i czasu trwania inwazji Ascaris suum Goeze, 1782

The studies were carried out on guinea pig males weighting about 280 g. The animals were infected with 5000 or 20000 invasive eggs of Ascaris suum. On the 3-rd, 7-th, 10-th and 14-th day of invasion the animals were dissected. Lungs were weighted, and the number of Ascaris larvaes was estimated using Baermann method. The activity of alpha-amylase (Fennel's method) and trypsin (Anson's method) were examined in pancreas homogenate. The infection of guinea pigs with A. suum larvaes resulted in a decrease of amylase and trypsin activity in parcreas. The activities were the lowest at the 3-rd day of invasion for amylase and at the 7-th day for trypsin. The results obtained for the animals infected 5 or 20000 invasie eggs A. suum did not differ statically.
