Spectrophotometric Determination of Corticosteroids and Its Application in Pharmaceutical Formulation

A simple, sensitive and economically viable spectrophotometric method for the determination of corticosteroids (predinsolone {PSL}, dexamethasone {DEX}, prednisone {PS}, betamethasone sodium phosphate {BEP} and hydrocortisone {HYD} has been developed. The method involves the oxidation of corticosteroids by iron (III) and subsequent complexation of iron (II) with potassium hexacynoferrate (III),...

Indirect Determination of Ascorbic Acid by Atomic Absorption Spectroscopy

A new and simple method followed by atomic absorption spectrometry has been developedfor indirect determination of ascorbic acid (AA). The proposed method was based on the oxidationof AA to dehydroascorbic acid with Cu2+cation(200mgL-1)in an ammonium thiocyanatesolution atpH2.4. AA reduces Cu2+to Cu+followed by the precipitation of Cu+ with SCN-. Then, the excess ofCu2+in the solution was measu...

Contribution of Indirect Causes to Maternal Mortalities Based on a Methodological Approach to Clinical Epidemiology in Iran

Introduction: Level of mothers’ literacy, pregnancy history of more than four times, residence in villages, lack of receiving intensive care during pregnancy, as well as inaccessibility to obstetric emergency services have been reported, in Iran and the world, as major factors for maternal mortality. Considering significance of identifying indirect causes of maternal mortalitie...
