Correlation between colonic secretion and colonic motility in rats: Role of ghrelin

Figure 1 Effects of acyl ghrelin and des-acyl ghrelin on the colonic transit time (A and F), fecal pellet output (B, C, G, and H), and total fecal weight (D, E, I, and J) during the first and second hour post-injection at different intracerebroventricular injection volumes (5 μL/rat: A-E vs 10 μL/rat: F-J). Data are presented as mean ± standard error of the mean. ^aP < 0.05, vs saline controls.

Figure 2 Pooled data demonstrating the relationships among total fecal weight (A-D), colonic transit time (A, B, C, and F), and fecal pellet output (C-F) stimulated by saline, acyl ghrelin, and des-acyl ghrelin with the intracerebroventricular injection volume at 5 μL.

Figure 3 The relationships among total fecal weight, colonic transit time, and fecal pellet output during the first hour post-injection stimulated by either acyl ghrelin (A and B) or des-acyl ghrelin (C and D) with the intracerebroventricular injection volume at 5 μL.
