A simple, rapid, accurate and precise spectrophotometric method is proposed for determination of pyridoxine hydrochloride (Vitamin B6) in pure form and in its pharmaceutical preparations and serum. The method is based on the oxidation-reduction reaction between vitamin B6 and cerium (IV) ion (ceric ion), then the subsequent reaction of cerium (III) with arsenazo III reagent in acidic medium in ...

Purpose: The aim of this study is to develop bromhexine hydrochloride 1 %w/v oral solution for veterinary use and to evaluate its stability. Methods: Solutions of Bromhexine hydrochloride (1%w/v) were prepared by dissolving bromhexine hydrochloride in benzyl alcohol at 50 °C then alcohol 96 % v/v; Tween 80 and purified water were added. The obtained solution was filled in amber glass bottles, a...

Positron annihilation lifetime (PAL) technique has been employed to investigate the effect of low doses of -irradiation (in air and vacuum) on the type of polymers namely: polystyrene (PS). A conventional fast-slow coincidence system was used for measuring the positron lifetime spectra. The time resolution of the system was ٤٢٢±٢٠ ps (the full width at half maximum (FWHM)) at Na energy window....

Concerns about traditional chemical pesticides has led to increasing research into novel mosquito control methods. This study compared the effectiveness of 2 different types of polystyrene beads for control of mosquito larvae in south-east Islamic Republic of Iran. Simulated field trials were done in artificial pools and field trials were carried out in 2 villages in an indigenous malaria area ...
