The frogs were experimentally exposed to sub-lethal concentrations (0.5mg bifenthrin/g of body weight) of Talstar 10EC for 3 weeks. The present study proves its toxic potential in terms of the damages in liver and kidney level. Tissues were normal in the control group. Hepatic lesions in frog exposed to bifenthrin were characterized by vacuolation of hepatocytes and nuclear pycnosis, perisinusoidal and periportal fibrosis, dilatation of Disse space and sinusoid capillaries, presence of cellular infiltrates. Kidney lesions consisted of dilation of BowmanĄŻs space, tubular necrosis, and epithelial cells shows pycnotic nuclei, discrete degree of interstitial edema. %K bifenthrin %K frog %K kidney %K liver %K pesticides %K pyrethroid %U http://www.bioresearch.ro/bioresearch/2012-1/005-010-AUOFB.19.1.2012-PAUNESCU.A.-U.Pit.Sci.Ecol.Env.Prot.Ro.-Histopathological.changes.pdf
