background: faba bean toxicity (favism) is a common condition observed in our region.   objective : to develop a short and simple technique involving the use of riboflavin-deficient rats to test in vivo faba bean toxicity.   methods/results: sprague dawley rats were maintained on a riboflavin-deficient diet and their vitamin b 2 status was monitored by the assay of erythrocyte glutathione reduc...

abstract   background: lead toxicity is caused by ingestion, inhalation, or contact with particles or vapors containing lead. it can present with nonspecific signs and symptoms such as abdominal pain, constipation, irritability, difficulty concentrating, and anemia. in this study, we have tried to find a relationship between lead poisoning and drug abuse.   methods: in a cross sectional study, ...

Background: Investigation of toxicity of silver nanoparticle, especxially blood toxicity, is necessary because this nanoparticle is used a lot in diffrerent parts of life and invironment. The aime of this is evaluation the effects of silver nanoparticles with different concentrations on blood cells pregnant Wistar rats. Materials and Methods: In this case control study, 30 pregnant rat wer...

Ethylene glycol (EG) is a toxic substance and EG metabolites cause metabolic acidosis. The major emphasis in this study to get rid of the toxicity before conversion its metabolites. interaction between ethylene ethanol has been studied using DFT (Density functional theory method). In blood; Glycolic acid more stable gloxal less stable. with considered for metabolism. Thermodynamic values obtain...

abstract in respect to nano-technological studies and physiological and biochemical lesions of these materials on aquatic animals, in this study we examine the toxicity effects of nano-zinc oxide (zno nps) on hematological indices of common carp (cyprinus carpio). lc50 of nano zinc oxide was determined according to the mortality at 24, 48, 72 and 96 hours, respectively. during separate experime...

The present study has been conducted on Caspian Roach (Rutilus rutilus) so that the impact of different concentrations lead on blood hematological, biochemical, and immunological indicators could be investigated. The roach (Rutilus rutilus), used in this study, was 3.3±0.3 g heavy and 4±0.80 cm long in average. The fish were exposed to a low concentration of 10% LC50 and high concentration of 5...
