background: muscle relaxant agents usually use to facilitate tracheal intubation; however, sometimes limitations exist. magnesium (mg) sulfate is a candidate for muscle relaxant substitute. this study was designed to determine the effect of mg sulfate accompanied with propofol and fentanyl in patients undergoing ophthalmic surgery. materials and methods: in a double?blind randomized protocol an...

preeclampsia is a major cause of morbidity and mortality during pregnancy. several independent investigators have demonstrated the association of androgens with hypertension. the main purpose of this study was to determine whether maternal levels of sex hormones, especially testosterone, are higher in patients with preeclampsia than in matched normotensive control subjects. serum levels of test...

AIMS To assess the value of a new rapid fluorescence method for the diagnosis of microsporidiosis in HIV seropositive patients. METHODS Microsporidian spores in stools were demonstrated by using the fluorochrome stain Uvitex 2B. The new technique was evaluated in three groups of HIV seropositive patients with diarrhoea. Group 1: 19 patients with biopsy confirmed E bieneusi infection (186 stoo...

objective(s) the aims of present study were to elucidate the effect of nahs as a h2s donor on precontracted rat trachea smooth muscle, role of epithelium and nitric oxide in this action. materials and methods tracheal rings from male adult wistar rats were isolated and mounted in an organ bath containing krebs–henseleit solution under 1.5 g resting tension and contractions were recorded isometr...

from june 1992 to march 1993, a group of patients suffering from different types of warts were treated with intralesional injections of bleomycin sulfate. this study reviews the literature concerning this modality of treatment and the pathophysiology and immunohistopathology of warts and options for treatment. in this prospective study, a combination of a i mg/ml solution of bleomycin in distil...

statement of the problem : geographic tongue is characterized by loss of filliform papillae in an erythematous area with keratotic borders. it vanishes after a while and reappears in another area. it is relatively common and is most seen among females. considering such problems as pain, burning sensation and sharp pain in tongue, decreasing of taste sensation, cancer phobia and esthetic problem...

results in all the groups, complete hemostasis occurred. hemostasis times of different concentrations of ferric sulfate were significantly less than those of the control group (p < 0.001). objectives this study attempted to determine the haemostatic effect of ferric sulfate and compare it with the standard method (suturing technique). materials and methods in this animal model study, 60 male wi...

aluminum sulfate nano structures have been prepared by solution combustion synthesis using aluminum nitrate nonahydrate (al(no3)3.9h2o) and ammonium sulfate ((nh4)2so4). the resultant aluminum sulfate nano structures were calcined at different temperatures to study thermal  decomposition of aluminum sulfate. the crystallinity and phase of  the as-synthesized and calcined samples were characteri...
