Figure 4. Figure 4. Representative photomicrographs showing tryptase positive mast cells (MCs) in the colonic mucosa of a healthy control (HCs) (a–c); an diarrhea predominant irritable bowel syndrome (IBS-D) patient with lactose malabsorption (LM) (d–f) and a patient with lactose intolerance (LI) (g–i). IBS-D patients with LI had increased mucosal MCs compared with LM and HCs [36].

説明

Representative photomicrographs of tryptase-positive mast cells in colonic mucosa compare healthy controls with IBS-D patients, suggesting mast cell involvement in lactose intolerance symptomatology.
