... in blood samples using a chemiluminometric assay. Fat content, superoxide dismutase (SOD), catalase and glutathione S-transferase (GST) activity in the liver were determined by Sudan staining and spectrophotometric assessments, respectively, from the fresh frozen tissue. Results: DHEA and the DHEAS...

... increased in various regions of brain and spinal cord. However, the activity of superoxide dismutase was decreased in cerebrum, hypothalamus, hippocampus, cerebellum, brain stem and spinal cord. The present communication demonstrates that the different parts of CNS at 13 and 26 weeks of age have lipid...

.... Tissue equivalent system Protein turnover Energy charge Redox state Two-dimensional electrophoresis Triosephosphate isomerase Superoxide dismutase Catalase Ultrastructure Abstract. The accumulation of modified proteins in aging is well documented in many aging models. For example...

...Lora E. Rikans; Cynthia D. Snowden; Danny R. Moore Antioxidant defenses within liver mitochondria are pivotal in preventing liver damage from oxidative toxicants. In this study we determined the activities of glutathione peroxidase (GPO), superoxide dismutase (SOD) and glutathione reductase (GRD...

...Jerome L. Sullivan Linear increase in the ratio of superoxide dismutase to specific metabolic rate as a function of maximum lifespan potential has been proposed as evidence that longevity may be controlled in part by the activity of this enzyme. A role for superoxide dismutase in aging...

...C.J. Lammi-Keefe; P.B. Swan; P.V.J. Hegarty The activities of total superoxide dismutase (SOD) and the manganese (Mn SOD) and copper-zinc (Cu-Zn SOD) forms were determined in the supernatant fraction of heart, liver and six skeletal muscles from rats during aging. Total SOD activity increased...

...Harold R. Massie; Trevor R. Williams; Valerie R. Aiello No significant differences were found in either mitochondrial or total superoxide dismutase activity levels in two different wild-type strains of Drosophila melanogaster whose life spans differed by 40%. The strains used were Oregon R...

... of this work was to analyze the activities of the two protective enzymes, superoxide dismutase (SOD) and catalase (CAT), and the levels of malondialdehyde (MDA) to examine the relationship between the ageing process and defence antioxidant and lipid peroxidation. Method: SOD activity was measured in red blood...

... was to analyze the activities of the protective enzymes superoxide dismutase (SOD) and catalase (CAT) in patients of both sexes affected by cataract. Methods: The SOD activity was measured in red blood cells using the Minami and Yoshikawa method, and the CAT activity was measured in haemolysates by the method...

... with controls. The maximum population doubling levels of the cells did not increase. In the cells incubated with BHP, the cytosolic superoxide dismutase activity was returned to its control value by WSP treatment (1.25–5 µg/ml). The cytosolic glutathione peroxidase activity progressively increased...
