EVALUATION OF THE CHOLINESTERASIC ACTIVIT Y IN THE DOG

Numerous methods have been described for the measurement of blood chol inesterasic activity. The two most commonly used methods are: the Mich el method, considered to be the standard method and the Ellman method, based on a colorimetric test used in many kits for diagnosis in human medicine. The use of such a kit in veterinary medicine was studied by measuring cholinesterasique activity in the pasma of 30 beagle dogs, the average level was 1745 +/- 600 UI/l. Cholinesterasique activity re mained stable when the samples were stored at 4 degrees C for 5 days. The method used allowed the surveillance of long-term exposure but the results are difficult to interpret in the case of a single exposure.
