Clinical Studies on Liver Catalase Activity in Gastric Carcinoma Cases

II. Experimental Supplement

抄録

Aqueous extracts were prepared from 39 gastric carcinoma tissues and injected into mice intraperitoneally, the liver catalase activity of which was measured. The results obtained are summarized as follows.
1. Liver catalase activities in mice injected with the tumor extracts were significantly lower than those in the control mice.
2. Catalase-lowering activity of a tumor extract was not dependent upon the macroscopic or microscopic features of the tumor.
3. Decrease in liver catalase activity of gastric carcinoma cases had little relation to the catalase lowering activity of the tumor extract, but showed close parallelism with the catalase-depressing ability of the tumor itself calculated under some assumptions
