Abstract

|
The toxicity of organophosphate is due to the disruption of the nervous system of birds through the inhibition of cholinesterase enzymes. Two dead white-napped cranes (Grus vipio) was found at Cholwon which is the most popular wintering site in Korea, and submitted to National Veterinary Research and Quarantine Service for diagnosis. Gross examinations revealed no evidence of any specific disease condition. Histopatholgically, only one bird incidentally had multifocal necrotizing hepatitis with intranuclear inclusion bodies in the liver which was considered to be Inclusion Body Disease of cranes. The contents of gastrointestinal tracts of the birds contained residues of parathion ranged as 67.4 and 42.1 ppm respectively, using by gas chromatography and mass spectrometry. Based on these evidences, parathion was responsible for the cranes mortality.
