the antioxidant activity of the melia azedarach was investigated in rats with ethanol-induced erythrocyte damage. chronic administration of ethanol (20% w/v, 2 g/kg.p.o.,daily for four weeks) increased the level of lipid peroxidation (lpo), decreased the activity of superoxide dismutase (sod) and catalase and reduced the content of glutathione (gsh). the concurrent treatment of ethanol-administ...

Superoxide dismutase (oxide dismutase) is an enzyme synthesized via the expression of SOD-related genes. It first line defense against oxygen free radicals, and it widely exists in cytoplasm, chloroplasts, mitochondria. However, SOD gene family woody plant Liriodendron chinense has not been studied. To reveal potential role genes, we systematically identified analyzed L. chinense, investigated ...

the aim of this study was to investigate the effects of ethanolic extract of the whole plant of phyllanthus rheedii wight p.rheedii as antihyperglycemic, antihyperlipidemic and antioxidant effect in streptozotocin (stz) induced diabetic rats. male wistar rats were administered p.rheedii (250 mg/kg) orally for 21 days and blood glucose level was measured weekly. at the end of 21 days, the serum ...

in order to study the effect of salt stress at different growth stages on physiological characteristics and enzyme superoxide dismutas (sod) activity in wheat genotypes a green house experiment was conducted at the agricultural research greenhouse, agricultural, medical and industrial research school, nuclear science and technology research institute of karaj. a split factorial design on the ba...

Telomerase enzyme is necessary for the elongation of telomeres while telomerase being critical aging and cancer. Metformin, ibuprofen, acetylsalicylic acid used in this research are drugs that millions people already use many likely to future. In study, effects these on activity Mus musculus swiss albino mice liver tissue were investigated was measured with a PCR-ELISA based kit. study possible...

This study examined the effect of increasing chloroplastic superoxide dismutase (SOD), ascorbate peroxidase (APX), or glutathione reductase (GR) activity via plant transformation of cotton on the initial recovery of photosynthesis following exposures to 10 degrees C and high photon flux density (PFD). Growing wild-type or non-expressing segregate plants (controls) and transformants at two PFDs ...

Coronary arterioles of exercise-trained (EX) pigs have enhanced nitric oxide (NO.)-dependent dilation. Evidence suggests that the biological half-life of NO. depends in part on the management of the superoxide anion. The purpose of this study was to test the hypothesis that expression of cytosolic copper/zinc-dependent superoxide dismutase (SOD)-1 is increased in coronary arterioles as a result...

In this study, the effects of salinity stress (NaCl) on the activity of Catalase (CAT), Guaiacol Peroxidase (POD), and Superoxide dismutase (SOD) were studied in leaves of fifteen oilseed rape (Brassica napus L.) cultivars (Champlain, Hayola401, Licord, Modena, NK Aviator, NK Karibik, NK Octan, Okapy, Opera, PF, RGS, RNX 3621, SLM046, Talayeh, Zarfam). Plants were grown in a greenhouse under co...

The objectives of this study were to (1) determine whether transgenic (Tg) mice overexpressing copper/zinc-superoxide dismutase (CuZn-SOD) are protected from the deleterious effects of gut ischemia/reperfusion (I/R) and (2) compare the effectiveness of Tg SOD overexpression in attenuating I/R injury to intravascularly administered CuZn-SOD or manganese (Mn)-SOD. The accumulation of fluorescentl...
