FIGURE 3.
Effects of orexin-A in the CeA on the gastric emptying. 0.05, 0.5, 5 μg orexin-A, 5.0 μg SB-334867 or 0.5 μg orexin-A + 5.0 μg SB-334867 was microinjected into CeA from cannula on the head of rats, respectively. 0.5 and 5 μg orexin-A increased gastric emptying obviously and the effect of 0.5 μg orexin-A could be blocked by 5.0 μg SB-334867. Data are represented as mean ± SD, n = 6. Data were analyzed using one-way ANOVA followed by a Bonferroni post hoc test to compare the effect of different orexin-A groups and Student’s t-test was used to determine the effect of SB-334867. *P < 0.05, compared with NS group; #P < 0.05, compared with 0.5 μg orexin-A group. NS, normal saline.
