Two Arabian horse stallions with behavioural problems were treated with long-acting neuroleptics in order to facilitate corrective training. Perphenazine enanthate, administered intramuscularly at a dose of 0.5 mg kg-1 had an effect for 30 d. Pipothiazine palmitate (1 mg kg-1) induced tranquilization of 30 d duration as well as extra-pyramidal clinical signs, ataxia and aphagia. Neither horse showed prolapse of the penis or haemolysis.

Rats injected i.p. with AF64A at a dose of 1/3 to 11/25 LD50 showed transient signs of motor disturbance such as ataxia, squatting down and respiratory distress and also longer lasting signs consisting of adipsia, aphagia and loss of body weight. Twenty-four hours after a single injection with AF64A (129 mumol/kg), ACh contents in the cerebral cortex, hippocampus and striatum decreased significantly, and the content in the cerebral cortex still remained at a lowered level even 10 days after injection. When rats received AF64A i.p. with an initial dose of 129 mumol/kg and nine consecutive daily doses of 12.9 mumol/kg and thereafter they were kept with no medication for at least 20 days, the ACh contents in the three brain regions were still significantly reduced. ACh release by electrical stimulation or K+, but not spontaneous release, was significantly reduced in the AF64A treated rats. The T-maze spontaneous alternation behavior in rats treated with AF64A was impaired. The present results indicate that AF64A administered i.p. can induce a long lasting defect in central cholinergic transmission.
