摘要：

The satiating effect of intravenous fat infusions was investigated in sham-feeding rats. Intralipid infusions at loads of 2.5-10.0 kcal were administered into either the inferior vena cava or the hepatic-portal vein during sham feeding. Intravenous infusions of Intralipid by either route had no effect on sham feeding during 60-min tests. In earlier work we found that duodenal infusions of Intralipid rapidly inhibited sham feeding and elicited behaviors typical of satiety under test conditions identical to those of the present study. The lack of effect of intravenous infusions of Intralipid on sham feeding is further evidence for a preabsorptive site of action for t.he satiety effect of Intralipid.
