Liver catalase activity, one of the free-radical scavenger enzymes, has been measured in 22 normal subjects and compared with that of 13 patients suffering from hepatocellular carcinoma. The activity was estimated both in tumor tissue and in tumor-free tissue. A significant reduction of catalase activity was noted in tumor tissue (p less than 0.001) as well as in the adjacent tumor-free tissue (p less than 0.02). In patients with hepatoma, the serum iron level was lower than in normal (p less than 0.01) and was correlated with enzyme activity (r = 0.958). These findings suggest that in hepatocarcinoma the free radical scavenger system is impaired.

Abstract

Liver catalase activity, one of the free-radical scavenger enzymes, has been measured in 22 normal subjects and compared with that of 13 patients suffering from hepatocellular carcinoma. The activity was estimated both in tumor tissue and in tumor-free tissue. A significant reduction of catalase activity was noted in tumor tissue (p less than 0.001) as well as in the adjacent tumor-free tissue (p less than 0.02). In patients with hepatoma, the serum iron level was lower than in normal (p less than 0.01) and was correlated with enzyme activity (r = 0.958). These findings suggest that in hepatocarcinoma the free radical scavenger system is impaired.
