Blood Superoxide Dismutase and Catalase Activities in Women Affected with Breast Cancer
Catalase ROS
2009/12/30
Experimental and epidemiological evidences implicate the involvement of oxygen derived radicals in the pathogenesis of cancer development. Oxygen derived radicals are able to cause damage to membranes...
Failure of heparin, superoxide dismutase, and catalase to protect against decompression sickness
Catron,PW Thomas,LB McDermott,JJ Holt,MA Harabin,AL Flynn,ET
2009/7/14
The effects of heparin (HEP), superoxide dismutase (SOD), and catalase (CAT) on the course of decompression sickness (DCS) were studied in anesthetized dogs (Canis familiaris). Animals were divided in...
The Effects of Vitamin E on Catalase Activies in Various Rat Tissues
catalase Vitamin E kidney heart rats
2009/7/3
Vitamin E and other antioxidants prevent or minimize oxidative damage in biological systems. The level of antioxidant defense sufficient to protect the organism from high free radical concentrations i...
Age-Related Alterations in Superoxide Dismutase and Catalase Activities in Rat Brain
Aging SOD catalase cerebral cortex cerebellum brain rats
2009/7/2
Active oxygen species have been proposed to be involved in the aging process of the brain, therefore alterations in the activities of enzymes involved in the defense system against free radicals and o...
A Comparison of Erythrocyte Superoxide Dismutase and Catalase Activity in Patients With Hepatitis C Infection
Hepatitis C superoxide dismutase catalase interferon alpha
2009/6/26
Hepatitis C virus (HCV) infection remains important due to difficulties in treatment up to a chronic state. It is considered that free radicals, lipid peroxidation and antioxidant defense play a role ...
Morphologic changes induced by short-term ischemia in the rat testis are not affected by treatment with superoxide dismutase and catalase
short-term ischemia rat testis superoxide dismutase and catalase
2009/2/23
Short-term testicular ischemia was induced unilaterally by ligating the testicular artery for 60 or 100 minutes in adult rats. After 7 days, the rats were fixed by vascular perfusion. The effect of ...
Catalase and oviductal fluid reverse the decreased motility of bovine sperm in culture medium containing specific amino acids
Hydrogen peroxide oviduct secretions toxicity
2009/2/17
The motility and velocity of bovine spermatozoa incubated in TCM-199 are reduced in comparison with those incubated in a simpler media made for sperm, such as modified Tyrode (Sp-Talp). Moreover, ...
Catalase mRNA expression in the male rat reproductive tract
Catalase mRNA expression male rat
2009/2/16
Reactive oxygen species (ROS) have been shown to impair sperm function. The actions of ROS are reduced by antioxidant enzymes, including catalase. Although catalase-like activity has been demonstrated...
Developmental expression of glutathione peroxidase, catalase, and manganese superoxide dismutase mRNAs during spermatogenesis in the mouse
Antioxidant enzymes gene expression testis translational regulation
2009/2/16
We have examined in mouse testis the steady-state levels of mRNAs encoding glutathione peroxidase (GSHPx), catalase (CAT), and superoxide dismutase 2 (SOD-2), three enzymes essential for the antio...
High catalase content of rabbit semen appears to be inherited
High catalase rabbit semen inherited
2008/12/25
Reactive oxygen species, as hydrogen peroxide, can be damaging to sperm. Most species have little protective catalase in their semen, but rabbit semen contains substantial amounts of catalase. The...
Survival and In Vitro Fertility of Boar Spermatozoa Frozen in the Presence of Superoxide Dismutase and/or Catalase
Antioxidants cryopreservation sperm porcine
2008/12/22
In the present study the potential benefit of reactive oxygen species (ROS)-scavenging enzymes superoxide dismutase (SOD) and catalase (CAT) when cryopreserving boar spermatozoa was evaluated. Poole...
ACTIVITY OF SUPEROXIDE DISMUTASE AND CATALASE IN PEOPLE PROTRACTEDLY EXPOSED TO LEAD COMPOUNDS
lead superoxide dismutase catalase malondialdehyde
2010/12/24
Lead can modify pro/antioxidant status by influencing antioxidant enzymes. As the results of experimental researches are divergent, the purpose of this research was to evaluate the activity of enzymes...
