background: to explain the role of arthroscopic release in intractable frozen shoulders. we used different questionnaires and measuring tools to understand whether arthroscopic release is the superior modality to treat patients with intractable frozen shoulders. methods: between 2007 and 2013, in a prospective study, we enrolled 80 patients (52 females and 28 males) with recalcitrant frozen sho...

i ntroduction: due to the increase in le fort surgeries and its effect on nose widening, it seems necessary to use an alternative method without this effect. the present research examined the effect of alar release on interalar changes in le fort i osteotomy. m at erials and methods: the study population included patients admitted to bou-ali hospital in 2012-2013 undergoing le fort i osteotomy....

introduction: today, with development of various industries, the adverse events originated from explosion and emission of toxic and chemical substances have increased. these events may cause serious environmental problems that threaten human health and safety. therefore, knowledge about the risk of toxic substances from industrial facilities is essential. although, chlorine is extensively utili...

in this study, tretinoin microemulsion has been formulated based on phase diagram studies by changing the amounts and proportions of inactive ingredients, such as surfactants, co-surfactants and oils. the effects of these variables have been determined on microemulsion formation, particle size of the dispersed phase and release profile of tretinoin from microemulsion through dialysis membrane. ...

the purpose of this study was to prepare and characterize nimodipine loaded microspheres using ethyl cellulose (ec) as a carrier polymer through an emulsion solvent evaporation method. these evaluations characterized the pattern of drug release from prepared microspheres. nimodipin loaded microspheres were prepared using an emulsification solvent evaporation method. the effect of process variab...

background: to evaluate safety and efficacy of percutaneous release of trigger finger in multiple digits involvement in comparison with  single digit involvement.   method: a number of 100 patients (131 fingers) were treated by percutaneous release and divided into two groups: single digit (group a) and multiple digits (group b). they were followed up for one year. success rate, pain, complicat...

triptoreline is a potent agonist of luteinizing hormone-releasing hormone, currently used in the treatment of prostatic cancer where therapy may be required over months or years. frequent injection of drug decreases patients’ compliance. the present study describes the formulation of a sustained release microparticulate drug delivery system containing triptoreline acetate, using poly (d,l lacti...

the aim of this study was to formulate and evaluate microencapsulated controlled release preparations of a highly water/soluble drug, salbutamol sulphate by (water in oil) in oil emulsion technique using ethyl cellulose as the retardant material. various processing and formulation parameters such as drug/polymer ratio, stirring speed, volume of processing medium were optimized to maximize the e...

this study was performed to design bilayer regioselective floating tablets of atenolol and lovastatin to give immediate release of lovastatin and sustained release of atenolol. bilayer floating tablets comprised two layers, i.e immediate release and controlled release layers. the immediate release layer comprised sodium starch glycollate as a super disintegrant and the sustained release layer c...
