Abstract
The purpose of this work was to investigate for the first time histopathologic effects of carbaryl in liver and kidney tissues of Bufotes variabilis. After 96h following exposure to carbaryl (low dose: 0.05, medium dose: 0.1 and high dose: 0.2mg/g), the toads were euthanized and dissected. In liver tissue, vacuolization in hepatocytes, necrosis, mononuclear cell infiltration, an increase in melanomacrophage number, enlargement of sinusoids, hemorrhage and congestion were determined in exposed toads. In kidney tissue, mononuclear cell infiltration, hypertrophied Bowman's capsule cells, deformation, vacuolization, karyolysis and necrosis of renal tubule epithelium, brush border destruction, glomerular shrinkage, hemorrhage and fibrosis were observed in carbaryl-treated groups. According to this investigation, carbaryl caused histopathologic damages in liver and kidney tissues of B. variabilis.
