Multiple sclerosis (MS) is a disease characterised by perivascular infiltrates and demyelination of the white matter in central nervous system. Although precise cause MS remains unknown, some investigations have been carried out on antioxidant mechanisms these patients.In this study, malondialdehyde (MDA), as lipid peroxidation marker, ceruloplasmin (Cp) transferrin (Trf), proteins, levels were determined cerebrospinal fluid (CSF) serum 30 patients before after corticosteroid therapy 20...

Peripheral blood cultures were exposed to various doses (5 500 mg/L) of boron compounds. Sister-chromatid exchange, micronucleus and chromosomal aberration tests applied estimate the DNA damage, biochemical parameters (superoxide dismutase, catalase, glutathione peroxidase, glutathione-S-transferase, glucose-6-phosphate dehydrogenase, total glutathione, malondialdehyde antioxidant capacity) examined determine oxidative stress. According our findings, compounds at low useful in supporting...

Context Nigella sativa L. (Ranunculaceae) (NS) is traditionally used to treat many conditions such as inflammation. Objective This study evaluates the effects of NS seeds ethanol extract in paracetamol-induced acute nephrotoxicity rats. Materials and methods Forty-eight female Wistar Albino rats were divided into eight groups: I = sham; II sham + 1000 mg/kg NS; III 140 (N-acetyl cysteine) NAC; IV 2 g/kg paracetamol; V paracetamol VI, VII VIII 250, 500 NS, respectively. Paracetamol...

Pesticide toxicities are common in aquatic ecosystems and affects livings negative. Therefore, it is important to strengthen the antioxidant system organisms protect against these toxic chemicals. In this study, simulative toxicity was established fish then healing process followed. For purpose, rainbow trout Oncorhynchus mykiss exposed cypermethrin left recovery with either N-acetyl cysteine (an antioxidant, 0.5 mM–1.0 mM concentrations) or no intervention (self-healing) for 96 h. context,...

Introduction: Behçet’s disease (BD) is a chronic systemic disorder characterised by oral and genital ulcerative lesions, ocular cutaneous manifestations. Cytokines are the major mediators of immunologic inflammatory reactions. Nitric oxide reactive nitrogen intermediate which plays key role in pathogenesis many autoimmune skin diseases. The study was conducted to determine serum interleukin-2 (IL-2), interleukin-6 (IL-6), tumour necrosis factor (TNF)-alpha nitric levels relation disease....

Genetic, neuropathological and biochemical investigations have revealed meaningful relationships between aluminum (Al) exposure neurotoxic hematotoxic damage. Hence, intensive efforts are being made to minimize the harmful effects of Al. Moreover, boron compounds used in a broad mix industries, from cosmetics pharmaceuticals agriculture. They affect critical biological functions cellular events enzymatic reactions, as well endocrinal mineral metabolisms. There limited dose-related data about...

Carvone (CVN) is a monocyclic monoterpene found in the essential oils of Mentha spicata var. crispa (Lamiaceae) and Carum carvi L. (Apiaceae) plants has been reported to have antioxidant, antimicrobial, anticonvulsant, antitumor activities. The beneficial health properties CVN encouraged us look into its anticancer activity. To best our knowledge, reports are not available on activity cultured primary rat neuron N2a neuroblastoma (NB) cells. Therefore, present study an attempt toward...
