| Abstract | ||
| The levels of lead (Pb+2), copper (Cu+2) and cadmium (Cd+2) in blood of both domestic and wild quails were monitored. Lead content in domestic quail (4.97 ppm) exceeded that in the wild ones (3.35 ppm). Relatively low levels of copper were detected. Cadmium in the wild slightly exceeded that in the domestic ones. On the other hand, eight enzyme systems were assayed. They were acetyl cholinesterase (AChE). butyryl cholinesterase (BuChE), adenosine triphosphatase (ATPase). acid phosphatase (APase), glutathione S-transferase (GST), glutamic oxaloacetic transaminase (GOT). glutamic pyruvic transaminase (GPT) and delta aminolevulinic acid dehydratase δ-ALAD). The interaction of heavy metals with quail enzyme systems was studied. Generally, δ-ALAD was affected by most of the heavy metals. although it is highly responsive to lead. Mercury and cadmium showed mild inhibition of AChE and BuChE. The largest interaction of mercury was shown as a higher inhibition of APase. On the other hand. thiodicarb showed full inhibition of AChE, while fenvalerate did not show any interaction with AChE. BuChE was moderately inhibited by both insecticides. | ||
