Abstract :
Breast tumor patients generally have more oxidative stress than normal females. This was clear from significant decrease (P 0.05) in tissue GSSG-Red activity. The study had found that free radicals in malignant breast tumors were higher than benign tumors, therefore the GSH- Red might be used as markers for prognosis of the disease. Results of molecular characterization show optimum enzyme concentration substrate conc., optimum pH, temperature time effect of some (chemotherapies in constant conectrations) for GSSG-Red activity.
