A gasometric method to determine erythrocyte catalase activity.
We describe a new gasometric method to determine erythrocyte catalase activity by the measurement of the volume of oxygen produced as a result of hydrogen peroxide decomposition in a system where enzyme and substrate are separated in a special reaction test tube connected to a manometer and the reagents are mixed with a motor-driven stirrer. The position of the reagents in the test tube permits...
متن کاملVariations in catalase activity in human leukocytes.
By CHEV KIDS0N C ATALASE is an enzyme found in most body tissues which has the capacity to release molecular oxygen from hydrogen peroxide ( H202 ) . It is concerned with peroxidation of substrates such as alcohol, phenol, formate and formaldehyde.1 Catalase in blood has aroused considerable interest, the enzyme content being higher than that in other tissues except liver.2 Most studies have co...
متن کاملHepatic Catalase Activity in Advanced Human Cancer1
Hepatic catalase activity in unanesthetized man has been de termined by measuring the disappearance rate of hydrogen perox ide spectrophotometrically in homogenates from needle biopsy specimens of liver. Ten healthy male prisoners, 59 patients with advanced cancer, and 60 cadavers shortly after death with cancer were studied. There is a wide range of catalase activity in normal human liver. Cat...

متن کاملLiver and blood cell catalase activity of tumor-bearing mice.
One of the earliest reports on the systemic effects of tumors was made by Brahn (2), who found that the liver catalase activity of human beings with cancer of the rectum, stomach, pancreas, and intestine was very much lower than normal. This systemic phenomenon later was studied extensively by Greenstein et al. (4-8) with the use of a large number and variety of tumor-bearing mice and rats. How...
