Aim of this study was to investigate the involvement of the mitochondrial permeability transition pore (MPTP) and oxidative stress in the cardioprotective effect of vasopressin (AVP) on ischemia/reperfusion (I/R) injury. Anesthetized male wistar rats were subjected to regional 30 min ischemia and 120 min reperfusion and randomly divided into nine groups:(More)
CONTEXT Temporal lobe epilepsy (TLE) is an intractable neurological disorder. Rosmarinic acid (RA) is a natural polyphenol with antioxidant, anti-apoptotic, and anti-inflammatory properties. OBJECTIVE This study evaluates beneficial effect of RA in intrahippocampal kainate-induced model of TLE. MATERIALS AND METHODS Rats were divided into sham,(More)
1. Stroke is accompanied by a robust inflammatory response, glutamate-mediated excitotoxicity, release of reactive oxygen species and apoptosis. Thiazolidinediones, which target the nuclear receptor peroxisome proliferator-activated receptor (PPAR)-g, have been reported recently to exhibit potent anti-inflammatory and anti-oxidant actions and inhibit both(More)
Based on our previous finding that chronic lithium treatment reduced naloxone-precipitated withdrawal syndrome in morphine-treated mice, the effect of chronic lithium treatment was evaluated on the development of dependence to clonidine. Dependence was induced by injection of either morphine (50, 50 and 75 mg/kg, intraperitoneally with 3 hr interval for 3(More)
OBJECTIVE Examine the normal adult internal organ weight and its relationship with body height, body weight, body mass index and age. MATERIALS AND METHODS Prospective analysis of data from 1222 autopsies in Legal Medicine Organization of Iran from 1st January, 2007 to 1st September, 2008. All the subjects were adult residents of Tehran died from external(More)
1. In endothelium-containing rings of rat aorta, precontracted by phenylephrine, addition of acetylcholine (Ach), resulted in a concentration-dependent relaxation through the release of endothelial dependent relaxing factors, including nitric oxide (IC50 = 8.41 microM). 2. Pretreatment of the tissues with 20 microM indomethacin, significantly decreased the(More)
1. Supraspinal opioid antinociception is mediated, in part, by connections between the periaqueductal grey (PAG) and the rostral ventromedial medulla (RVM). Morphine antinociception from the PAG is decreased by serotonin, N-methyl-d-aspartate (NMDA) and opioid receptor antagonists administered into the RVM. Because the brain isoform of nitric oxide synthase(More)
The aim of the present study was to investigate the protective effect of various doses of exogenous vasopressin (AVP) against ischemia-reperfusion injury in anesthetized rat heart. Anesthetized rats were randomly divided into seven groups (n=4-13) and all of them subjected to prolonged 30 min regional ischemia and 120 min reperfusion. Group I served as(More)
This paper analyzes the public healthcare expenditure of Middle Eastern countries in relation to different exogenous explanatory variables, through a panel study involving twelve (12) Middle East countries. More specifically, the study methodology uses panel cointegration, and panel-based error correction models derived from annual data covering the period(More)
Context: Neuropathic pain is a common and disabling complication. To develop a better treatment of the neuropathic pain, a comprehensive understanding is essential. In this paper, we review pathophysiological principles of neuropathic pain, focusing on synaptic plasticity and long-term potentiation (LTP) in the nociceptive circuits. Finally, the role of(More)
