摘要

The action of ivermectin on sensitive behavioral tasks in mice, during treatment for mites within a barrier facility, was investigated. 21 (5 males, 16 females) mice (129/SvEv) were used for measuring body weight, open field locomotor activity and rotarod motor coordination. For acoustic startle and prepulse inhibition, 20 C57BL/6J and 29 AKR/J mice were studied. For the Morris water task, the same 20 C57BL/6J mice were studied. Ivermectin (0.08% sheep drench) was administered in the drinking waterof the home cage for 8 weeks. Control groups received normal tap water. Ivermectin did not affect general health, body weight, motor coordination, swimming behaviour, or spatial learning in several inbred strains of mice, but it induced a small but significant effect on some sensitive behaviours, including exploration of a novel open field, the acoustic startle reflex and prepulse inhibition of the acoustic startle reflex, a measure of sensorimotor gating. It is concluded that a cautious approach to initiating ivermectin treatment in mice should be used for sensitive behavioural experiments.
