Materials and met...
background: to attain whether the effects of low and high doses of estrogen progesterone luteinizing hormone (lh) and follicle stimulating hormone (fsh) in acute and chronic administration were related to oxidant and antioxidant parameters in rat uterine tissue as well as cyclooxygenase-1 (cox-1) activity. materials and methods: acute and chronic administration of estrogen (1 and 5 mg/ kg) prog...
Background and Aim: Considering the acute and chronic effects of organic solvents to which vehicle painters are exposed for long periods of time, their evaluation and control is crucial for protection of health of the employees.

A few studies have shown that stress and glucocorticoids probably interfere in pain control. The aim of this study was to investigate the role of dexamethasone(Dex) as a glucocorticoid receptor agonist on acute and chronic pain in formalin test in mice. In this study male albino mice(n=60) in 6 groups(25-30gr) were used. Dex ( 0.5, 1 and 2mg/kg) was injected 30 min before test and str...

The alteration in the levels of plasma corticosterone, brain norepinephrine (NE), and expression of brain heat shock proteins (Hsp70) after different durations of noise exposure (acute, 1 day; sub-acute, 15 days; chronic, 30 days) has been studied to analyze their role in combating time-dependent stress effects of noise. Broadband white noise (100dB) exposure to male Wistar albino rats signific...
