Growth of Acetobacterium woodii on fructose was stimulated by Na+; this stimulation was paralleled by a shift of the acetate-fructose ratio from 2.1 to 2.7. Growth on H2-CO2 or on methanol plus CO2 was strictly dependent on the presence of sodium ions in the medium. Acetate formation from formaldehyde plus H2-CO by resting cells required Na+, but from methanol plus H2-CO did not. This is analog...

A simple, sensitive, and convenient spectrophotometric method for the determination of diclofenac sodium and piroxicam in pure form and in pharmaceutical formulations was developed. The method is based on the oxidation of diclofenac sodium or piroxicam by iron(III) in the presence of o-phenanthroline. The formation of tris(o-phenanthroline) iron(II) complex (ferroin) upon the reaction of diclof...

The turbidimetric methods here described are based on the formation of relatively insoluble complexes between isolated acid mucopolysaccharides and cetyltrimethylammonium bromide.’ Some of the properties of these complexes have recently been described by Scott (1). We found that the amount of turbidity developed when the cetyltrimethylammonium bromide is added to a solution of acid mucopolysacc...

In the preformulation study physical compatibility of the drug-excipient was screened and compatibility was observed between Zaltoprofen and selected solubilizers. In the drug solubilizers interference study no interference was observed in UV spectrophometric analysis of Zaltoprofen in presence of employed solubilizers. Aqueous solubility of Zaltoprofen was found 0.028 mg/ml. The solubilizers s...

Diclofenac sodium or Sodium-2-[(2, 6-dichlorophenyl) amino] phenyl] acetate, is widely used as non-steroidal antiinflammatory agent in therapeutics, it inhibits the cyclooxygenase enzyme1. Various spectrophotometric2-11, chromatographic12-18, colorimetric19-20 and flourimetric21-23 methods have been developed for quantification of diclofenac sodium. Extensive literature survey revealed that a v...

Administration of sodium [1,2-14C2]oxaloacetate and sodium [1-14C]acetate to Scilla maritima plants yielded labelled scillirosid. A systematic degradation of scillirosid indicated that the alpha-pyrone ring of the bufadienolide is formed by the condensation of a pregnane derivative (derived from mevalonic acid via squalene) and one molecule of oxaloacetic acid.

Rumen-fistulated lactating cows were individually fed on hay or silage and intakes were monitored during 3 h treatment periods and for 2 h after. Each experiment used five, six or seven animals and the treatments were applied in a Latin Square design. Sodium acetate infusions of 1.8-11.0 mol in 4.5 litres water caused a dose-related depression in hay intake, the extent being 82 g dry matter (DM...
