X-ray studies on phospholipid bilayers. XI. Interactions with chloramphenicol.

Chloramphenicol is a widely used antibiotic with low levels of toxicity. However, scanning electron microscopy revealed morphological changes in human erythrocytes when they interacted in vitro with therapeutical concentrations of chloramphenicol. To explain this shape change, a study concerned with the possible interactions of this antibiotic with bilayers built-up of phospholipids located in ...

Quantum Theoretical studies of Nanostructures onto Hydrogen Adsorption on V-surface

We have studied the adsorption processes of H2 on the V (100) surface of Vanadium using self consistent field theory.Dissociative adsorptions of H2 are significantly favored compared to molecular adsorptions. There is a significant charge transfer from the first layer of the vanadium surface to the Hydrogen atoms. Three possible adsorption sites, top, bridge and center site, were considered in ...

Chloramphenicol (chloromycetin), an Antibiotic. Pharmacological and Pathological Studies in Animals.

It is a neutral white crystalline substance with a bitter taste and is stable in neutral and acid solutions. The drug is moderately soluble in water (0.25 per cent at room temperature, 0.65 per cent at 700 C and up to 15 per cent in propylene glycol, 5 per cent in 50 per cent acetamide), and is insoluble in vegetable oils. Solubility in urine or serum is about the same as in water. Solutions ar...

BIOCHEMICAL STUDIES ON CHLORAMPHENICOL (CHLOROMYCETIN*) III. ISOLATION AND IDENTIFICATION OF METABOLIC PRODUCTS IN URINEt

When chloramphenicol is administered by mouth to normal human subjects, only 5 to 10 per cent of the administered dose is excreted unchanged in the urine, as determined by microbiological assay methods (3, 4). However, with calorimetric methods for aromatic nitro compounds (5), from 75 to 90 per cent of the administered dose is accounted for in 24 hour urinary excretion in man (3). The major po...
