Arginase distribution in tissues of domestic animals.
1. A new colorimetric method was used for determination of arginase in different tissues of some domestic animals. 2. In all species studied liver was the richest source of arginase. 3. Significant differences were observed in the specific activity of arginase in livers from different species. 4. In all species, besides liver, kidney and brain also contained significant levels of arginase. 5. In the dog, in addition to the three organs mentioned above, lung, heart, spleen and skeletal muscle showed some arginase activity. 6. In sheep and cattle significant arginase activity was observed in the rumen. No differences were observed between epithelial and muscular layers of different parts of digestive system in all species studied. 7. These results are discussed in terms of the possible role of arginase in different tissues of animals.
