From: Tonic contraction develops in the colon during anaphylactic hypotension in anesthetized rats
Summarized data of the intracolonic pressure at baseline and during tonic contraction (a) and the duration of tonic contraction (b) in the control (white bars, n = 8), anaphylaxis (black bars, n = 8), parasympathectomy (stripe bars, n = 8), sympathectomy (gray bars, n = 8) and parasympathetic deafferentation (dark gray bars, n = 8) groups. Values are expressed as mean ± SEM. Tonic contraction was not detected in the control group (N.D.); *P < 0.05 versus the baseline; #P < 0.05 versus the anaphylaxis group. Summarized data of the time-course changes in the colonic contraction frequency (c) and mean colonic contraction amplitude (d) after antigen injection in the control (circle, n = 8), anaphylaxis (square, n = 8), parasympathectomy (inverted triangle, n = 8), sympathectomy (triangle, n = 8) and parasympathetic deafferentation (diamond, n = 8) groups. Values are expressed as means ± SEM. Open symbols, P < 0.05 versus the baseline
