Retinaranitidine as an alcohol dehydrogenase inhibitor in acute methanol toxicity in rats

Methanol poisoning is a hazardous intoxication characterized by visual impairment and formic acidemia. The therapy for methanol poisoning is alcohol dehydrogenase (ADH) inhibitors to prevent formate accumulation.  Ranitidine has been considered to be an inhibitor of both gastric alcohol and hepatic aldehyde dehydrogenase enzymes. This study aimed at testing ranitidine as an antidote for methanol acute toxicity and...

Micronucleus test in post metamorphic Odontophrynus cordobae and Rhinella arenarum (Amphibia: Anura) for environmental monitoring

The genotoxic effect of cyclophosphamide and glyphosate in a commercial formulation were determined using the micronucleus test in peripheral blood erythrocytes of Odontophrynus cordobae and Rhinella arenarum, amphibians widely distributed in the Province of Córdoba, Argentina. For this, the basal frequency of the micronucleated erythrocytes (MNE) was determined by: 0.40±0.18 MNE/1000...

Removal of some heavy metal ions from their aqueous solutions by duckweed

Duckweed was used to study adsorption of several metal ions (Fe2+,Cu2+, Zn2+ and Pb2+)  from wastewater under different conditions .The dried leaves of duckweed were used at different adsorbent/metal ion ratios. The experimental conditions which includes, pH, contact time, initial concentration, and loading weight on the removal process were investigated. Bach adsorption was studied in a room temperature. The...

GST polymorphic status modifying the arsenic induced clinical manifestations in people of the southern part of West Bengal, India

Persons chronically exposed to environmental arsenic through their drinking water experience various arsenic induced clinical manifestations which includes keratosis and pigmentary changes in the skin. However the response varies widely among persons. To study whether Glutathione-S-Transferase (GST) gene polymorphism plays any role in this variation, a total of 78 study subjects were recruited from the villages of...
