OBJECTIVE We evaluated the effect of pretreatment with nitric oxide precursor before ischemia on recovery with reperfusion in rat hearts. METHODS Isolated rat hearts were perfused with Krebs-Henseleit buffer without (C group) or with 3 mmol/L L-arginine (A group) before 30 minutes of ischemia. The left ventricular function, including heart rate, developed pressure, maximal dp/dt, and coronary...
BACKGROUND The purpose of this study was to investigate the short-term effect of topical antiglaucoma medication on tear-film stability, tear secretion, and corneal sensitivity in healthy subjects. METHODS In this prospective, double-blind crossover trial, break-up time and basal secretion (Jones test) were measured 60 minutes before, and 30, 60, and 90 minutes after topical antiglaucoma drop...

Introduction: Intensive care unit is one of the most stressful wards for patients and it is estimated that 30 to70 percent of patients experience severe physiologic stress during admission. Some of the physiologic responses to stress include increase in metabolic rate with consequent increase in body temperature, increase in cardiac output and contraction power and subsequently increase in bloo...
Objective: This study investigated whether delta-neutrophil index(DNI) and neutrophil/lymphocyte ratio (NLR) values have prognostic significance in wound infections after cesarean section.
 Material Methods: In this retrospective study, one hundred ten patients who developed infection were rehospitalized section a tertiary health center between 2015 2019 formed the group. The same number o...
background: complaining of tearing was found in some of our patients after phacoemulsification surgery for senile cataract. secondary acquired lacrimal drainage obstruction has been proposed to happen due to different causes. this study was performed at feiz hospital in isfahan, iran from september to december of 2004 to evaluate the effects of phacoemulsification surgery on tear drainage in ey...
Background/Aims When a person is experiencing stress, corticotropin-releasing hormone (CRH) can modulate gut physiologies, such as visceral sensation or gastrointestinal motility, and its intravenous administration mimics stress-induced physiological changes. However, the influence of CRH on the esophagus is yet unknown. Accordingly, we investigated whether intravenous CRH administration increa...
Bacterial contamination of gastrointestinal fibre-endoscopes is a potential source of clinically significant infection. Aqueous 2% alkaline glutaraldehyde adequately disinfects fibre-endoscopes but may cause serious sensitivity reactions among endoscopy staff. A new 'closed-system' disinfecting apparatus is described that disinfects with glutaraldehyde for 30 minutes before an endoscopy session...
