Progressive compromise of antioxidant defenses and free radical-mediated lipid peroxidation, which is one of the major mechanisms of secondary traumatic brain injury (TBI), has also been reported in pediatric head trauma. In the present study, we aimed to demonstrate the effect of melatonin, which is a potent free radical scavenger, on brain oxidative(More)
Melatonin has recently been suggested as an antioxidant that may protect neurons from oxidative stress. Acute ethanol administration produces both lipid peroxidation as an indicator of oxidative stress in the brain and impairs water-maze performance in spatial learning and memory tasks. The present study investigated the effect of melatonin against(More)
OBJECTIVE To study the potential nephroprotective role of agomelatine in rat renal tissue in cases of contrast-induced nephrotoxicity (CIN). The drug's action on the antioxidant system and proinflammatory cytokines, superoxide dismutase (SOD) activity, levels of glutathione (GSH) and malondialdehyde (MDA) and the gene expression of interleukin-6 (IL-6),(More)
Human leukocyte antigen (HLA) B27 has a strong association with ankylosing spondylitis (AS) and other spondyloarthropathies. More than 70 subtypes of HLA B27 have been described. The present study investigated B27 subtype distribution among B27-positive patients with AS classified according to the modified New York criteria and healthy controls.(More)
Increased oxidative stress and hemorheological disturbances may play very important roles in the development of microangiopathies in diabetes mellitus. This study was designed to determine the healing effect of melatonin on hemorheological parameters and diabetic nephropathy in streptozotocin (STZ)-induced diabetic rats. Wistar male rats were divided into(More)
Sepsis and sepsis-related acute lung injuries (ALIs) are one of the main causes of death among hospitalized patients. Renin–angiotensin–aldosterone system (RAAS) has been reported to have role in sepsis. However, there is no study on aliskiren, a renin inhibitor, on sepsis-induced ALI. We aimed to investigate the potential protective effects of aliskiren in(More)
This study investigated possible role of U-II and its receptor expression in inflammation by using UTR agonist and antagonist in carrageenan induced acute inflammation. Rats were divided into 5 groups as (1) Healthy control, (2) Carrageenan control, (3) Carrageenan +Indomethacin 20mg/kg, orally, (4) Carrageenan +AC7954 (U-II receptor agonist,(More)
PURPOSE Myocardial infarction (MI) is one of the most prevalent causes of sudden adult death. It is difficult to diagnose early MI postmortem because there are no typical or characteristic changes in morphology. In this study, changes in the level of the mRNA for the urotensin receptor (UR) were investigated postmortem to determine the suitability of UR as(More)
PURPOSE Previously blocking the renin angiotensin system (RAAS) has been effective in the prevention of gastric damage. Therefore, the aim of this study was to investigate the effects of aliskiren, and thus, direct renin blockage, in indomethacin-induced gastric damage model. METHODS Effects of aliskiren were evaluated in indomethacin-induced gastric(More)
10.7247/jiumf.2012.19.1.23_25 Ankilozan spondilit (AS) etyolojisi bilinmeyen kronik enflamatuvar bir hastalıktır. Patogenezde genetik ve çevresel faktörlerin önemli rol oynadığı bilinmektedir. AS gelişimi ile HLA B27 arasında güçlü bir birliktelik saptanmıştır. Bu çalışma ile daha önceki literatür bilgileri ışığında bölgemizdeki HLA B27-AS ilişkisi(More)
