The measurement of blood cholinesterase activity is a useful tool for monitoring exposure to organophosphate and carbamate insecticides. Blood cholinesterase activity is measured colorimetrically or electrometrically. Recently, a simple and practical electrometric method has been described and validated for measuring blood cholinesterase activity in people(More)
Metoclopramide is a dopamine receptor antagonist used in animals as both an antiemetic and a gastroprokinetic agent. In chickens, the drug causes central nervous system depression. The authors examined the potential sedative and hypnotic effects of metoclopramide when administered in combination with the anesthetic agent ketamine in 1-3-week-old chicks.(More)
A modified electrometric cholinesterase method has been described for use in ruminants exposed to organophosphate insecticides. The method was used to measure cholinesterase activities in the plasma and erythrocytes of sheep, goats and cattle treated with organophosphate insecticides under field conditions. The animals were treated topically to control(More)
Plasma and brain cholinesterase activities were determined in three wild bird species to assess their exposure to organophosphate and carbamate insecticides which are used in agriculture and public health. In the present study, we used an electrometric method for measurement of cholinesterase activities in the plasma and whole brain of three indigenous wild(More)
