The aim of this study was to investigate the effect of thiamine and thiamine pyrophosphate (TPP) on oxidative stress induced with cisplatin in liver tissue. Rats were divided into four groups; thiamine group (TG), TPP + cisplatin group (TPG), healthy animal group (HG), and cisplatin only group (CG). Oxidant and antioxidant parameters in liver tissue and AST, ALT, and LDH levels in rat sera were...

Background: Recurrent aphthous stomatitis (RAS) is the most common inflammatory ulcerative condition of oral cavity. The aim of this study was to compare the levels of the salivary Malondialdehyde (MDA) and total antioxidant capacity (TAC) and blood parameter in RAS versus healthy controls. Methods: This case-control study consisted of 28 patients with RAS and 28 age and sex -matched control...

BACKGROUND Oxidative stress may be involved in the pathogenesis of every human disease. To understand its possible role in benign prostatic hyperplasia (BPH), we measured the overall oxidative status of patients with BPH and the serum activity of the high density lipoprotein (HDL)-related antioxidant enzymes paraoxonase 1 (PON1) and arylesterase (ARE). METHODS Fifty-six urology outpatient cli...

In sickle cell anemia (SCA), inflammatory (i.e., intravascular sickling and transient vasoocclusive) events result in chronic endothelial activation. In addition to sickling behavior, sickle (SS) red blood cells exhibit abnormal interaction with the vascular endothelium, which is considered to have an important role in initiation of vasoocclusion. Upregulation of endothelial adhesion molecules ...

OBJECTIVES This study was aimed to investigate the protective effects of dexpanthenol (Dxp) on against cisplatin-induced ototoxicity. METHODS To examine this effect, distortion product otoacoustic emissions (DPOAEs) measurements and serum levels of oxidative and antioxidant status (including malondialdehyde, superoxide dismutase, catalase, glutathione, glutathione peroxidase, total oxidant st...

background stroke is the second cause of death and disability in the world, and oxidative stress which could be considered as a prognostic factor in patients for prevention, follow up and determination of stroke’s severity has a conceivable role in neural damage. objectives the aim of our study was to explain the association between oxidant/antioxidant imbalance as a prognostic factor in patien...

Welding is a process during which fumes, gases, electromagnetic radiation and noise are emitted as by-products. Metal oxide particles are particularly hazardous components of welding fumes. Welding has been found to be associated with respiratory symptoms and our objective in the present study was to study the effects of welding on pulmonary function and serum oxidant-antioxidant status. Fifty-...
