Abstract/OtherAbstract:
In a previous study we found that while human satietin (h-SAT) suppressed the food intake of rats it was also aversive to them. In the present study rat satietin (r-SAT) was tested for aversiveness in rats fitted with chronic third ventricle (ICV) cannulas. The rats were then given access to water for 1-hr/day and food ad lib for ten days. Fluid intake, food intake during fluid access and 24-hr total food consumption were recorded. The rats were then ICV infused with saline and 30 min later half of the animals given access to banana flavored water (Group 1) while the remainder were presented with almond flavored water (Group 2). The next day Group 1 was infused with saline and Group 2 with 100 micrograms/rat of r-SAT. Thirty minutes later the flavors presented to the rats were the reverse of the previous day. Satietin significantly reduced food intake during fluid access and for 24 hours. Thereafter, fluid and food ingestion of the groups was normal and similar. Thus no rebound feeding occurred in the r-SAT treated group. Two days after r-SAT or saline the rats were given a two-bottle choice test. Both groups displaced equal preference for the flavors, therefore r-SAT produced no taste aversion. The r-SAT treated rats lost more body weight than saline treated animals the first day after treatment. This difference increased the next day and remained significant for seven days post infusion, whereas, food consumption did not differ between the groups after the first day. The data indicate the food intake suppression in rats produced by r-SAT is not due to the compound being aversive.
