in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
In the myenteric plexus-longitudinal muscle bioassay, ,'-endorphin, i.e., fl-ipotropin (-LPH){81-91J, has a potency of 450 with confidence limits of 281when Met5enkephalin is used as a reference standard with a potency of 100. The primary amide and the ethylamide of Met5-enkephalin have potencies statistically overlapping with that of f.endorphin. The primary amide of a-endorphiu has twice the ...
