[Behavior of serum and erythrocyte cholinesterase in experimental tetanus in rabbits]

In rabbits injected i.m. with 1 MLD of tetanus toxin, the levels of the serum cholinesterase and of the erythrocytic cholinesterase were determined twice every day, during the course of the intoxication, until the death of the animals. The levels of the serum cholinesterase were decreasing day by day, while these of the erythrocytic cholinesterase did not show any significant variation. These results are strictly comparable to those one may observe in organophosphorus poisoning.
