Fig. 2From: Tonic contraction develops in the colon during anaphylactic hypotension in anesthetized ratsSummarized data of the time-course changes in the systemic arterial pressure (a) and heart rate (b) 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 mean ± SEM. Open symbols, P < 0.05 versus the baseline; #P < 0.05 versus the anaphylaxis groupBack to article page
