Relationship between mucosal histamine levels and mucosal damage markers. (a) Correlation between mucosal histamine levels and the degree of mucosal oedema (the ratio of the wet weight to the protein content in the colonic mucosa). The line represents the regression line for data from both Ws/Ws and control rats (Y = 0.038X − 0.011, R = 0.778, P < 0.01). (b) Correlation between mucosal histamine levels and the ratio of the macroscopically damaged area to the entire colonic surface (Y = 0.9074X + 0.4916, R = 0.623, P < 0.05).
