title: Granisetron attenuates exercise-induced conditioned taste aversion in the rat.
abstract: A conditioned taste aversion (CTA) paradigm was used in the present study to investigate whether CTA produced by exercise could be attenuated by the 5-HT(3) receptor antagonist granisetron. Male Sprague-Dawley rats were randomly allocated to one of four groups (Ns=6) and were exposed to salty (0.128 M sodium chloride) or sour (0.00138M citric acid) solutions. Subjects were injected with either saline solution (1.0 ml, 0.9%) or granisetron (0.5mg/kg, IP) and were exposed to 30 min of forced wheel running exercise (70 revolutions/30min) 10 min after injection. Exercise induced CTA to both the salty (3.7 ml intake) and sour-flaroured (3.1ml intake) solutions as compared with no exercise (intake 14.0 and 13.7 ml), and administration of granisetron significantly attenuated the exercise-induced CTA to the salty- and sour-flavoured solutions.
