Eosinophil counts in the jejunal mucosa of Cftr −/− and Cftr +/+ mice. Hematoxylin-eosin staining of female mice jejunum showed the presence of eosinophils infiltrating the mucosa in the Cftr−/− specimen (d) compared to the Cftr+/+jejunum (b). In contrast, no such difference is observed in the male specimens (a and c). Black arrows indicate the presence of eosinophils. (e) Quantitation of eosinophils in the intercryptic lamina propria of Cftr−/− and Cftr+/+ mice from both genders. Results represent the means ± SEM of n = 4 and 5 Cftr+/+ males and females respectively, and 4 and 4 Cftr−/− males and females. 400 × magnification. *p <0.03 vs. Cftr+/+ females
