Stanley N. Wiemeyer M. P. Dieter 1978 <p>1. Activities of creatine phosphokinase, glutamic oxalacetic transaminase, glutamic pyruvic transaminase, lactate dehydrogenase, fructose diphosphate aldolase and cholinesterase were measured in plasma of bald eagles.</p><p>2. There were no sex differences in the plasma enzyme activities.</p><p>3. An acute dieldrin dosage (10 mg/kg) of a female bald eagle resulted in 400% increases in activities of plasma creatine phosphokinase and glutamic oxalacetic transaminase and 250% increases in activities of lactate dehydrogenase and glutamic pyruvic transaminase.</p><p>4. At 11 days post-dosage all but one of the plasma enzyme activities had returned to normal; glutamic oxalacetic transaminase activity remained 100% above pre-dosage values.</p><p>5. Plasma enzyme assays constitute a non-destrcutive procedure that can be used in valuable wildlife species to screen for the presence and prevalence of environmental contaminants.</p> application/pdf 10.1016/0306-4492(78)90125-9 en Elsevier Six different plasma enzymes in bald eagles (<i>Haliaeetus leucocephalus</i>) and their usefulness in pathological diagnosis article
