Assessment of a magnetic bead-EIA based kit for rapid diagnosis of fish pasteurellosis.

The accuracy of the magnetic beads-EIA based BIONOR AQUAEIA-Pp kit for the rapid diagnosis of pasteurellosis was evaluated. The kit reacted with all the Photobacterium damselae subsp. piscicida strains included in this study, with a detection limit of 10(4) bacteria/ml.

Mechanisms of the preventive properties of some garlic components in the carbon tetrachloride-promoted oxidative stress. Diallyl sulfide; diallyl disulfide; allyl mercaptan and allyl methyl sulfide.

Previous studies evidenced that garlic extracts and/or garlic components were able to prevent against chemically induced tumors or acute toxic effects of chemicals (e.g. CCl4 induced liver injury).

Rat liver nuclear nifurtimox nitroreductase activity.

Nifurtimox (Nfx) 4-[(5-nitrofurfurylidine)amino-3-methylthiomorpholine-1-1-di oxide] is a drug that is being used to treat American Trypanosomiasis (Chagas' disease). Nfx has serious toxic effects including mutagenic, reproductive and carcinogenic actions. Its toxicity has been linked to NADPH dependent nitroreductive metabolic biotransformation with production of oxygen reactive species.

Depression of liver microsomal glucose 6-phosphatase activity in carbon tetrachloride-poisoned rats. Potential synergistic effects of lipid peroxidation and of covalent binding of haloalkane-derived free radicals to cellular components in the process.

Depression of liver microsomal glucose-6-phosphatase (G6Pase) activity is a relevant feature of CCl4 poisoning. In vitro studies from several laboratories led to the hypothesis that a CCl4 promoted lipid peroxidation (LP) process is responsible for that effect. In vivo studies from our laboratory with potent antioxidants in dosage regimes inhibiting LP, however, were in contrast with that hypothesis.
