LPS injected intraperitoneally delays gastric emptying as reflected by increased stomach content in rats. The animals were left undisturbed in their cages and had access to food and water ad libitum until measurement points. After the rats had been decapitated for blood collection, their stomachs were carefully harvested and the contents weighed. Rats injected with vehicle had significantly lower gastric contents at 6 h compared to 3 h. bw = Body weight. Bars: means ± SEM of the number of rats indicated at the bottom. ∗ p < 0.05, ∗∗ p < 0.01 compared with vehicle at the respective time point; ^† p < 0.05 compared with vehicle at 3 h.
