conclusions increment in the number of parity can lead to decrease antioxidant defense mechanisms in multiparous women and their newborns. so, control of oxidative stress is considered to be beneficial in multiparous women. background parturition has been associated with free radicals, itself linked with poor pregnancy outcome. objectives this study aimed to investigate the relationship between...

The objective of the study was to see if oxidative damage is involved in organophosphorus-induced delayed neurotoxicity (OPIDN) and its subsequent alleviation through antioxidants. A total of 72 hens aged 56 weeks were divided into 4 groups (n=18).Group 1 sham, Groups 2, 3 and 4 were administered chlorpyrifos (CPS) @ 350mg/kg BW s.c. in divided doses over a period of 24 hrs. To prevent death du...

statins have antioxidant and anti-inflammatory effects that are not directly related to their cholesterol-lowering activity. this study aimed to investigate the effect of simvastatin on the extent of tissue damage in cisplatin-induced nephrotoxicity. simvastatin was orally given to rats in different doses (1, 2 and 4 mg/kg), 1 h prior to cisplatin injection (5 mg/kg, i.p.). all animals were dec...

background: prepubertal varicocele has the most devastating effects on the testes. oxidative stress is the major cause leading to infertility in varicocele. the antioxidant properties of flaxseed (fs) treatment in some oxidative diseases have been reported. objective: this study aimed to evaluate the antioxidant effect of fs in prepubertal rats with experimental varicocele. materials and method...

introduction: acrylamide (acr) known as a neurotoxic agent in human and animals. previous studies have been shown; fasudil improves neurological deficit and neuronal damage. in this study, the effect of fasudil, potent rho-kinase inhibitor, on acr-induced cytotoxicity was evaluated using pc12 cells as a suitable in vitro model. materials and methods: pc12 cells were exposed to different concent...

conclusions hemodialysis exacerbates oxidative stress and conformational changes of hb in patients with diabetes on hemodialysis. the frap value can be used as a positive determinant, while pco and hb derivatives can be used as negative determinants of oxidative stress in patients with diabetes. background diabetes is associated with an increased generation of reactive oxygen species (ros), whi...

objective: hexavalent chromium [cr (vi)] compounds are well-known environmental contaminants  generated from industrial processes. several studies have reported the harmful effects of cr (vi) on different organs, however, little is known about neurotoxic effects of cr (vi). the aim of this study is to investigate the toxic effects of cr (vi) on pc12 cells. methods: pc12 cells were cultured foll...

The study aimed to the investigation of the toxicity of organophosphorus pesticides malathion (MLT) and diazinon (DZN) in Wistar rats in a repeated dose study for 35 days. MLT and DZN in corn oil vehicle were oral administered. Body and organs weights, plasma and brain cholinesterase activities, serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities, histopathologi...

In the second part of review, aspects changes in magnesium metabolism under conditions severe stress, mechanisms anti-stress protection body with participation magnesium, features water-electrolyte at cellular level, anti-inflammatory effect and role processes detoxification acute poisoning certain poisons are consi-dered. The main body’s defence to suppress oxidative stress by limiting product...

selenium plays an important role in biological system due to its incorporation in glutathione peroxidases and thioredoxin reductase as prosthetic group, the pharmacological studies of synthetic organoseleno-compounds revealed these molecules to be used as antioxidants, enzyme inhibitors, neuroprotectors, antitumor, anti-infectious agents, cytokine inducers and immuno-modulators. the present stu...
