Beneficial Effects of Prebiotic Saccharomyces cerevisiae Mannan on Allergic Asthma Mouse Models

Figure 3

Effect of SC-MN on airway mucin in allergic mice. PAS staining visualizes neutral mucins (magenta material indicated by arrows) from tissue morphology at day 31. Intranasally administered SC-MN effectively blocked the ovalbumin- (OVA-) induced increase in mucin in small airway tissue sections. Similar results were obtained at day 45.
