[Lymphoid tissue in the wall of adult human gallbladder].
Lymphoid structures of mucosa and muscular coat from the gall bladder cervix, body and fornix were examined in histological preparations using morphometry and methods of variation statistics. Lymphocyte concentration in the organ walls grows proportionally to age. In the first period of maturity lymphoid nodules are absent in mucosal lamina propria while lymphoid nodules are rarely encountered among the cells of the fibroblastic series. Connective tissue layers of muscular coat are predominant sites of lymphoid aggregations. Senescence is characterised by the appearance of lymphoid nodules in the gall bladder mucosa. Cell concentration, structure and composition per unit area depend on nodule localization and the age of the individual.
