Sakaguchi K, Nagayama M, Masaoka T, Nishimura A, Kageyama K, Shirai M, Akahori F: Effects of fenthion, isoxathion, dichlorvos and propaphos on the serum cholinesterase isoenzyme patterns of dogs. Vet Hum Toxicol. 1997 Feb;39(1):1-5.
The serum cholinesterase (ChE) isoenzyme patterns consist of 5 bands for normal beagle dogs. We examined the ChE isoenzyme patterns and ChE activities of 4 groups, each of which consisted of 4 dogs, given the organophosphate (OP) compounds fenthion (P = S type), isoxathion (P = S type), dichlorvos (P = O type) or propaphos (P = O type) po at 220, 75, 120 or 90 mg/kg respectively. Blood samples were collected for 30 d after the OP administrations. ChE isoenzyme bands 4 and 5 were inhibited 12 h after fenthion and isoxathion administration; dichlorvos and propaphos produced suppression of main bands 4 and 5 20 min after administration. This change was effective to differentiate the type of OP administered (P = S and P = O), while the main ChE isoenzyme bands of dog serum reflected inhibition of serum ChE activity. |
