Proteinase activity in the pancreas of fish and amphibians

Enzyme activities expressed as the equivalent amount of bovine trypsin (casein or BAEE) or chymotrypsin (BTEE) under the same conditions. ^a measurements of enzyme activity in the pyloric cecal tissue may account for the lower values, ^b frogs were fed, ^c frogs fasted at 5 C, * group C: 0-20 µg RNase per gram of pancreatic tissue.
