title: DNA content of macrophages in pulmonary granuloma induced in rats by complete Freund's adjuvant.
abstract: Pulmonary granulomas were induced in rats with complete Freund's adjuvant. Histologic and cytologic alterations and Feulgen-DNA amounts determined by a cytophotometric method were studied. Fourteen (hours after injection, the pulmonary interstitia were thickened by cell infiltration. After 3 days; small granulomatous nodules developed containing macrophages, epithelioid and giant cells. The Feulgen-DNA amounts increased significantly in the course of the first day and reached peak values on the 3rd day. Then they showed a tendency to decrease after the 7th day. The present results confirm the previously obtained data, revealing the stimulating effect of the complete Freund's adjuvant on cell metabolism, DNA synthesis included.
