Involvement of parasympathetic pelvic efferent pathway in psychological stress-induced defecation

Table 1 Number of luminal fecal pellets remaining in the distal colon and rectum after sham stress or water-avoidance stress

	Number of fecal pellets in the distal colon and rectum
	Sham stress (A)	WAS (B)	(B) - (A)
Sham op (Vag)	2.1 ± 0.4	1.5 ± 0.2	-0.6
Vag	3.0 ± 0.4	1.2 ± 0.5a	-1.8
Sham op (RNT)	2.3 ± 0.5	1.1 ± 0.3	-1.2
RNT	4.1 ± 0.4c	4.3 ± 0.4d	0.1

Each value represents the mean ± SE (n = 6-8 per group).

^aP < 0.05 vs sham stress;

^cP < 0.05 ,

^dP < 0.01 vs sham operated (sham op) rats. WAS: Water-avoidance stress; Vag: Vagotomy; RNT: Rectal nerve transection.
