background: this study was designed to investigate the effect of intravenous magnesium sulfate on hemodynamic changes induced by pneumoperitoneum in patients undergoing laparoscopic cholecystectomy. methods: a randomized, placebo controlled study was performed on 52 asa class i or ii aged 20-70 years patients undergoing laparoscopic cholecystectomy with pneumoperitoneum with carbon dioxide. bef...

statement of problem: pulpotomy is the most common pulp treatment of primary molars. formocresol pulpotomy has enjoyed long-term clinical use and success, but concerns over its toxicity and mutagenicity have prompted research into other pulpotomy techniques. purpose: the aim of the present study was to compare the relative success of formocresol, ferric sulfate and mta pulpotomy methods in prim...

background: the aim of this study was to evaluate the effect of two injections doses of magnesium sulfate for controlling and reducing hemodynamic changes caused by laryngoscopy and endotracheal intubation in pregnant women who were candidates for caesarean section with general anesthesia. methods: in this controlled randomized double-blind clinical trial, 165 pregnant women who were candidates...

to study the role of preoperative intravenous magnesium sulphate in decreasing post-cesarean pain and opioid requirement during first 24hrs.in a double blind randomized clinical trial, prior to induction of general anesthesia, fifty elective cesarean candidates were randomly assigned to one of the two groups of placebo or magnesium sulfate. after surgery visual analogue scale (vas) and infused ...

conclusions intravenous etomidate 0.03 mg/kg prior to induction can effectively reduce the incidence and severity of myoclonus linked to etomidate. results the incidence and intensity of myoclonus were significantly lower in the low-dose etomidate group. the incidence rates of myoclonus were 51 (71.85%), 61 (85.9%), 30 (42.3%) and 41 (57.7%), and the percentages of patients who experienced grad...

background preterm premature rupture of membrane (pprom) prior to 37 weeks’ gestation is among the most common obstetrics problems, which is associated with prenatal mortality and several maternal and neonatal complications. history of pprom is a risk factor for recurrence. zinc has an important effect on the strength of membranes by affecting collagen [tensile] strength - a substance with immu...

background protein-bound toxins such as indoxyl sulfate (is) are not efficiently removed by conventional hemodialysis (hd). objectives to improve the removal of is, we performed an in vitro study to evaluate the effects of high dissolved hydrogen on the dissociation of is from albumin using simulated hd. materials and methods wasted dialysate from peritoneal dialysis was concentrated a hundred ...

introduction: ferric sulfate pulpotomy is a safe and effective method of the pulpotomy of primary teeth. but the results of different studies indicate low success rate of ferric sulfate pulpotomy in comparison to formocresol pulpotomy and a portion of these failures may be related to stimulating and harmful effects of zinc oxide eugenol paste. the aim of this study was to determine and compare ...
