By means of radioactive iodine it was demonstrated in this laboratory that surviving slices of thyroid tissue can incorporate inorganic iodide into diiodotyrosine and thyroxine (1). When 300 mg. of thyroid slices were incubated for 2 hours in a Ringer’s medium containing radioactive inorganic iodide, as much as 60 per cent of the labeled iodine was organically bound, about 50 per cent as diiodo...

The influence of flower extract of Jasminum grandiflorum was studied for its wound healing activity at a dose of 250 mg/kg body weight, using excision and dead space wound models in rats. The animals were divided into three groups in excision wound model, the controls (n=10) were treated with 0.25% CM cellulose, reference standard (n=10) were treated with sulfathiazole ointment and the experime...

Lack of correlation between quantitative minimal inhibitory concentration (MIC) determinations and disk diffusion susceptibility tests in our laboratory prompted a study to reevaluate the use of the disk diffusion test for sulfonamide susceptibility testing of Neisseria meningitidis. One hundred and sixty-three recent clinical isolates of N. meningitidis were examined for sulfonamide susceptibi...

The formation and physical stability of amorphous sulfathiazole obtained from polymorphic forms I and III by cryomilling was investigated by X-ray powder diffraction (XRPD) and near-infrared (NIR) spectroscopy. Principal component analysis was applied to the NIR data to monitor the generation of crystalline disorder with milling time and to study subsequent recrystallization under different sto...

Background Gallibacterium anatis is an opportunistic pathogen of intensively reared poultry causing oophoritis, salpingitis, peritonitis and enteritis. Gallibacterium anatis infection often remains undiagnosed. Recently multi-drug resistant isolates have been described. Methods A newly developed PCR restriction fragment length polymorphism assay targeting the 16S rRNA gene was used to identif...

The metabolic fate of p-aminobenzoic acid (PABA) in Escherichia coli is its incorporation into the vitamin folic acid. PABA is derived from the aromatic branch point precursor chorismate in two steps. Aminodeoxychorismate (ADC) synthase converts chorismate and glutamine to ADC and glutamate and is composed of two subunits, PabA and PabB. ADC lyase removes pyruvate from ADC, aromatizes the ring,...
