1. A method of measuring the denervating activity of a chemodenervating preparation comprisinginjecting a quantity of said preparation into a muscle or muscle group of an animal;
- permitting said preparation to diffuse within said muscle or muscle group thereby establishing a denervation field; and
determining the extent of the denervation field induced by said quantity of the preparation within said muscle or muscle group.

Abstract
The activity of chemodenervating agents can be ascertained by injecting locally a known quantity of the agent and determining the extent of inhibition of acetylcholine release about the locus resulting therefrom. Inhibition of acetylcholine release is indicative of denervation in a muscle, therefore the extent of inhibition of acetylcholine release is coextensive with the zone of denervation induced by the quantity of the agent.

13. A method of rapidly determining the extent of denervation induced by a unit quantity of a chemodenervating preparation comprising the steps of:
-
injecting said unit quantity of said chemodenervating preparation into a muscle or muscle group which controls eyelid movement of an animal; and ascertaining the degree of ptosis or globe prolapse resulting from said injection, wherein said degree of ptosis or globe prolapse is indicative of the spatial extent of denervation induced by said unit quantity. - View Dependent Claims (14, 15, 16)
