FIGURE 5.

Representative images of haematoxylin and eosin stain staining and quantification of lymphatic infiltration area fraction (%) in all groups of ileum sections. Aged rats’ ileum show increased lymphatic infiltration, but young plasma received aged groups improved these histopathological alterations. The blue arrow shows lymphatic infiltrates. Areas in the haematoxylin and eosin stain‐stained microphotographs of all groups were magnified in the photos to which they belonged to the area of interest. Values are expressed as mean ± SEM; n = 7 rats in each group. p ≤ 0.0001**** (nonparametric Mann–Whitney U‐test). Scale bar = 100 μm. YOcnt (aged control rats), OYcnt (young control rats), YOpls (young plasma recipient aged rats), and OYpls (aged plasma recipient young rats).
