Cancer and human liver catalase.
Data presented in the present paper indicate that human liver catalase depression is related to weight loss. A statistical study was first made to determine the catalase activity in correlation of the iodotitrimetric and spectrophotometric methods for biopsy and autopsy samples from cancer and cancer-free patients. Cancer patients had a 2~ per cent lower liver catalase activity than cancer-free...

متن کاملDepression of liver catalase by various agents.
I t is now a well established fact tha t liver catalase activity is diminished in tumor-bearing hosts which carry any one of a variety of types of cancer. Since the tumor may be located at a distance from the liver, the effect is systemic (2, 3, 9, 13, 19, 20, 24). Nakahara and Fukuoka (26, 27) have reported tha t the agent responsible for the depression of liver catalase is found abundantly in...
متن کاملTHE EFFECT OF GLUTARALDEHYDE ON CATALASE Biochemical and Cytochemical Studies with Beef Liver Catalase and Rat Liver Peroxisomes
Peroxidatic activity of catalase (E .C .1 .11 .1 .6) was discovered by Keilin and Hartree (1), and it has been firmly established that, catalase oxidizes various substrates such as ethanol, methanol, nitrite, and formate (2-4) . Crystalline beef liver catalase, used as an enzyme tracer (5), and the peroxisomal catalase (6, 7) have been visualized cytochemically by a modification of the 3,3'diam...
متن کاملLiver catalase of tumor-bearing and leprous rats.
INTRODUCTION A decrease in the liver catalase activity in tumor-bearing rats was reported by Greenstein and collaborators in 1941 (1). Since the appear ance of this early report, the same authors have investigated the effects of a relatively large num ber of different tumors upon liver catalase activity in rats and mice (2-5). These studies have shown that the decrease in activity of the liver ...
