Abstract

The actual problem of modern medicine is the reaction of Bronchus associated lymphoid tissue in airways chronic allergic diseases, because the full functioning of the respiratory system depends on the state of its local immune system.

The aim – to study morphological changes in Bronchus associated lymphoid tissue of guinea pigs in the dynamics of experimental ovalbumin-induced allergic inflammation.

Material and Methods. We have studied the lung of 48 guinea pigs, using histological and morphometric methods, under conditions of experimental ovalbumin-induced allergic inflammation. To assess the structural and functional rearrangement of pulmonary lymphoid nodules, their diameter and number were determined.

Results. We have shown that sensitization and allergization with ovalbumin leads to a significant structural and functional rearrangement of Bronchus associated lymphoid tissue of guinea pigs in the form of the elevation in their number and diameter. We found more pronounced morphological changes in the late period of development of allergic inflammation in peribronchial lymphoid nodules, confirmed by the maximum magnification factor – 2.6 (p*/**<0.001) of the diameter of peribronchial lymphoid nodules in the 4th experimental group compared to the control.

Conclusions. Sensitization and inhalation with ovalbumin leads to structural reorganization of Bronchus associated lymphoid tissue of guinea pigs in the form of the elevation in their number and diameter, had the unidirectional staged character depending on localization of lymphoid nodules and the duration of the experiment and claimed proliferative changes in the cellular adaptive link of local lung immunity of guinea pigs in late period of allergic inflammatory process.
