In the previous reports, I dealt with the influence of the cancerous gastric juice on the liver catalase and also on the phosphatase. The liver arginase is the subject of the present paper. The results obtained were as follows;
1. The liver arginase activity of normal rats ranged from 24.3 to 38.4, and the average value was 31.2.
2. The activity of the enzyme was depressed by injection of the cancerous gastric juice, indicating 17.5-25.5, average 21.4.
3. No remarkable change of arginase activity was observed when injected non cancerous gastric juice as control experiment.
4. The precipitate of cancerous gastric juice by trichloracetic acid proved arginase depressing effect, but the supernatant fluid had no effect on the enzyme.
