Fig. 3From: Cellular and molecular changes and immune response in the intestinal mucosa during Trichinella spiralis early infection in ratsKinetics of histamine in intestinal fluids from small intestine during early T. spiralis infection. Histamine concentrations were determined using a commercial ELISA kit. Results are expressed as the concentration mean ± SD from 5 rats/dpi and 5 control rats. Data were analysed by one-way ANOVA followed by Tukey’s multiple comparisons test (nlme and multcomp packages, respectively; α = 0.05). Asterisks (*) represent significant differences between infected and non-infected animals: *P < 0.05, **P < 0.01, ***P < 0.001. Bars indicate significant differences among days. Numerals (#) above bars indicate significant differences between days: ##P < 0.01Back to article page
