It has been shown that sex steroid hormones have profound neuroprotective effects in experimental traumatic brain injury (TBI). Because the endogenous hormone levels are proven to differ with estrous cycle stage, we evaluated whether estrous cycle stage affects various outcomes following diffuse TBI. TBI was induced by Marmarou's method in normal cycling(More)
OBJECT Although there is evidence that estradiol has neuroprotective effects after traumatic brain injury (TBI) in female rats, it is unclear which estrogen receptor (ER) subtype, ERα or ERβ, mediates this effect. The authors therefore examined the roles of the different ERs in this effect. Here the authors used the ERα selective agonist propyl pyrazole(More)
The aim of this study was to determine the effect of opium on biochemical parameters in addicts with non-insulin-dependent diabetes mellitus (NIDDM). Twenty-three males and 26 females between 35 and 65 years of age, with NIDDM, addicted to opium, were selected as the case group. Twenty-three males and 26 females with NIDDM and no opium addiction served as(More)
BACKGROUND It is known that stress alters biological processes. The aim of the present study was to examine the effect of examination stress in young adult male and female students. METHODS Examination stress was studied in 28 young female and 21 young male volunteer students of Rafsanjan university of medical Sciences, 0.5 hour before Physiology(More)
It has been demonstrated that estradiol has neuroprotective effects after traumatic brain injury (TBI) in female rats. Since estrogen receptors have an important role in estradiol effects at the cellular level and the exact mechanism(s) of estradiol-induced neuroprotection has not yet been fully clarified, the present study was designed to determine the(More)
OBJECTIVE(S) We examined the effects of endurance exercise in the presence of Bunium persicum extract administration on lipid profile and cardiorespiratory capacity in hypercholesterolemic male mice. Materials and Methods : Forty male hypercholesterolemic mice were divided into four groups: Vehicle, Endurance exercise (EE), Bunium persicum extract (BPE),(More)
Objective: To evaluate the role of calcium channel blockers and their mechanisms of action on acute inflammation of rat paw. Material and Methods: The study was conducted using carrageenan-induced rat paw inflammation model. Two different doses of nifedipine and verapamil (25 and 400 μg/kg, i.p.) were used. Edema was assessed by calculating the volume(More)
The purpose of this study was to evaluate the effect of female sexual hormones on intestinal and serum cytokines following traumatic brain injury (TBI). Adult female rats were ovariectomized and distributed among the following 9 groups: (i) sham trauma, (ii) TBI (Marmarou's method), (iii) vehicle (dimethylsulfoxide) treated, (iv) estrogen (E2) treated, (v)(More)
BACKGROUND Accidents are the second reason for mortality and morbidity in Iran. Among them, brain injuries are the most important damage. Clarification of the effects of brain injuries on different body systems will help physicians to prioritize their treatment strategies. In this study, the effect of pure brain trauma on the cardiovascular system and lungs(More)
OBJECTIVES Cytokines such as IL-1β are involved in inflammatory responses. This study evaluated the role of two different kinds of drugs (ibuprofen and celecoxib) on brain IL-10 and IL-1β after traumatic brain injury (TBI) in male rats. MATERIALS AND METHODS Rats were assigned into 6 groups: intact, sham, TBI, and treated rats with vehicle, celecoxib or(More)
