[The reactivity of pulmonary and hepatic macrophages in normal and prestimulated animals].

The rate of blood clearing of colloidal carbon increased two-fold as compared to the controls 5 days after prodigiosin injection. This was attended by intensified recruitment of macrophages into the alveoli and increase in the number of phagocytizing macrophages in the interstitium of the lungs by 1.5 times above normal. After administration of zymosan granules, the rate of colloid carbon clearance increased 1.5-fold in 5 days and 2.5-fold on the 9th day; the recruitment of macrophages into the alveoli and the number of phagocytizing macrophages in the interstitium of the lungs increased two-fold. At the same time, granuloma-type mononuclear infiltrates formed in the lungs and liver. Prodigiosin injection increases the rate of blood clearance 1.2-fold in animals stimulated by zymosan granules, while the volume of mononuclear infiltration, which acquires a diffuse character, increases 2.5-fold as compared to the value in zymosan stimulated animals. The effects of phagocyte reconciliation may be directly related to exacerbations of chronic inflammatory diseases of different localization.
