Background: Fish have been at high risk of atrazine toxicity. Comparative atrazine toxicity on the tissues of Clarias gariepinus is scanty. Therefore, acute and chronic effects of atrazine on some biochemical parameters in Clarias gariepinus were investigated in this study. Methods: Atrazine toxicity was determined by assessing the responses of glucose, protein, alanine aminotransferase (ALT), ...

ammonia is the chief excretory product in fishes. however, non-availability of enough of water in the habitat, may lead to the formation of urea, in fishes. in the present study, the possible role of urea formation to avoid the toxicity of ammonia under water-restricted condition was tested in channa gachua. circulatory urea and ammonia were estimated in the blood of the fishes and glutamate de...

background: opium is a new source of lead and considered as a cause of lead poisoning. as anemia and lead poisoning affect growth and behavior negatively, their timely prevention, diagnosis, and treatment are essential. the aim of thi study is evaluation of the prevalence of anemia, iron deficiency anemia, and lead poisoning in children with opioid toxicity. materials and methods: in this cross...

The immunosuppressant tacrolimus has a narrow therapeutic window, necessitating therapeutic drug monitoring to maintain efficacy and minimise toxicity. There are very few reports examining the impact of impaired biliary excretion on tacrolimus blood levels or toxicity. We report the case of a 26-year-old combined liver and kidney transplant recipient, who developed acute biliary obstruction lea...

Introduction: Complications of zinc poisoning are analyzed in several studies. Among these, pulmonary fibrosis are reported. There is some doubts about chronic complications of zinc inhalation. Precise screening programs in zinc mine workers need previous knowledge of relative frequency of chronic complications due to zinc inhalation. So this study is held to recognize the complications and to ...

Background: Cadmium is known as a unique heavy metal compared to others, due to its long half-life, low discharge from the body, toxicity at low concentrations and accumulation in tissues. Methods: The effects of chronic and acute Cadmium (Cd) exposure were investigated on the morphology and histopathology of 24 field rats (Millardia meltada). The rats were divided into two groups of 12 each, ...

background: rosa damascena is a traditional medicinal plant used in asia to treat several ailments. this study reports in vitro and in vivo antioxidative properties and toxicity of methanolic and aqueous extracts of white rose, an indigenous variety of rosa damascena from iran. methods: the antimicrobial activities, total phenolics, antioxidative properties and the blood sera ferric-reducing an...

Background: Each toxic agent results in unique presentations, depending on what neurophysiological changes occur following exposure. Scientific understanding of lead toxicity in the organ systems and at low levels of exposure continues to evolve. However, effects of lead poisoning on the thyroid gland function are controversial. In this descriptive study, changes in thyroid hormones in patients...
