Dynamics of the cellular composition of lymphoid nodules in the lungs of guinea pigs sensitized with ovalbumin
The article discusses the morphological aspects of the dynamics of the cellular composition of lymphoid nodules in the lungs of guinea pigs as a result of an experimental ovalbumin-induced allergic process. We studied the reactivity of immunocompetent cells of lymphoid formations of the lungs after three times subcutaneous sensitization and subsequent 8-day intranasal aeroallergization with ovalbumin in the early and late stage period of the allergic inflammatory process by microscopic, morphometric and statistical methods. By help of morphometric analysis we demonstrate the general regularity of reactivity of a local specific link of the pulmonary immune system to the action of an allergen, which consists in the elevation of the average amount of immune cells of lymphoid nodules of the lungs, starting from the 30th to the 44th day after the start of the experiment. The maximal coefficient of increase by 5.8 times was observed in counting plasma cells among all types of immunocompetent cells of lymphoid nodules in the lungs during the experiment. It has been statistically proven that the implementation of the ovalbumin-induced allergic inflammatory process in the lungs proceeds according to the humoral type and the duration of its course is not limited by the direct influence of the allergen, it also continues after the end of its action, which is a manifestation of changes in compensatory-adaptive processes in the pulmonary immune system with ovalbumin-induced allergic inflammation..
