From: Oral administration of propionic acid during lactation enhances the colonic barrier function
Gas chromatograms of standard mixtures (a) and proximal colon contents of the control group and propionic acid group (b, d). Peak identification: 1: acetic acid; 2: propionic acid; 3: butyric acid. Concentration of propionic acid (mmol/kg) in the proximal colon contents for ten days of oral gavage with a normal saline solution or 200 mM propionic acid in Sprague-Dawley rats (c). Each value was presented as the mean ± SD (n = 8), and significant differences between the groups are indicated as *P < 0.05 according to the results of a t-test
