Depression of contact sensitivity and enhancement of antibody response in Pseudomonas aeruginosa-infected mice.
The effect of Pseudomonas aeruginosa infection on contact sensitivity to 2-phenyl-4-ethoximethylene-oxazolone (oxazolone) and on antibody response to sheep erythrocytes, horse erythrocytes, and Escherichia coli 0111:B4 lipopolysacharide was investigated in outbred C57BL/6 mice. Injection of 0.5 and 0.2 median lethal doses significantly depressed contact sensitivity to oxazolone, whereas injecti...
متن کاملMicrobial Transformation of Carbazole to Anthranilic Acid by Pseudomonas stutzeri.
This study examined the microbial transformation of carbazole (CZ) by an isolated bacterium that can use CZ as a sole carbon and nitrogen source. The strain identified as Pseudomonas stutzeri produced a large amount of anthranilic acid (AA) from CZ in the medium containing a nonionic surfactant. In dialysis culture using ion-exchange resin, 7.9 g/liter (58mm) of AA was accumulated from 15g/lite...
متن کاملAnaerobic degradation of 2-aminobenzoate (anthranilic acid) by denitrifying bacteria.
In the presence of oxygen many aminoaromatic compounds polymerize to form recalcitrant macromolecules. To circumvent undesirable oxidation reactions, the anaerobic biodegradation of a simple member of this class of compounds was investigated. Two strains of bacteria were isolated which degrade 2-aminobenzoate anaerobically under denitrifying conditions, with nitrate as the terminal electron acc...
متن کاملInhibition of the Na+/dicarboxylate cotransporter by anthranilic acid derivatives.
The Na(+)/dicarboxylate cotransporter NaDC1 absorbs citric acid cycle intermediates from the lumen of the small intestine and kidney proximal tubule. No effective inhibitor has been identified yet, although previous studies showed that the nonsteroidal anti-inflammatory drug, flufenamate, inhibits the human (h) NaDC1 with an IC(50) value of 2 mM. In the present study, we have tested compounds r...
متن کاملFrequency of contact sensitivity in patients with contact or Atopic Dermatitis with Patch test
Background and aim: Eczema is a common inflammatory skin disease. Although history and physical examination are important in diagnosis of allergen, because of extent of environmental allergens, those are not simply recognized. The objective of this study was to determine allergens in patients with contact or atopic dermatitis referred to Razi hospital.Materials and Meth...
