some 3, 5-diacyl or 3,5-diester 1,4-dihydropyridines were oxidized to the corresponding pyridine derivatives using hydrogen peroxide in aqueous ethanol in the presence of potassium bromide and acetic acid as the catalysts. the reaction was carried out in ethanol and products were isolated in high to excellent yields. however, oxidation of 3,5-diacetyl 1,4-dihydropyridines is slower than 3,5-die...

THE OBSERVATION", that experimental hypothermia is associated with increased myocardial excitability as evidenced by cardiac arrhythmias and an increased incidence of ventricular fibrillation, is well documented.Gollan, Eudolph, and Olsen found that in dogs induction of hypothermia to a rectal temperature of approximately 23 C. resulted in a significant decrease in potassium, increase in bromid...

Oral supplementation with potassium bromide (10, 20 and 40 μg/ml) to fifth instar larvae of CSR2, CSR4 and CSR2xCSR4 crossbreed races of the silkworm, Bombyx mori resulted in a significant increase in the fat body glycogen in all the treated groups and in all the three races of the silkworm, B. mori. The fat body protein content was increased with 20 and 40 μg/ml treated groups in CSR2 and CSR4...

BACKGROUND Various antiepileptic drugs (AEDs) are used for the management of canine idiopathic epilepsy (IE). Information on their clinical efficacy remains limited. A systematic review was designed to evaluate existing evidence for the effectiveness of AEDs for presumptive canine IE. Electronic searches of PubMed and CAB Direct were carried out without date or language restrictions. Conference...

Three new methods using titrimetric and spectrophotometry are described for the determination of Propranolol Hydrochloride (PPH) and Atenolol (AN) with potassium bromate as the oxidimetric reagent and acid dyes, Methyl orange and Indigo carmine. In direct titrimetric (method A), the drug is titrated directly with bromate in acid medium and in the presence of excess of bromide using methyl orang...
