Abstract

The turn-over of leukocytes at sites of inflammation in vivo is to a large extent uninvestigated, mainly due to the technical difficulties associated with sampling and analysis of the inflammatory exudate. This paper investigates the immigration of fluorescently labeled granulocytes into exudate chambers at 8 h and at 1, 3, and 6 days after implantation into abdominal muscle of rat. In each experiment, the circulating granulocytes were labeled by intravenous administration of the DNA-labeling fluorochrome Hoechst 33342 and allowed to migrate into the chamber during 6 h before harvesting the chamber exudate. The rate of granulocyte immigration into the chamber varied considerably over time, showing a minimum at 3 days after implantation. The resulting kinetic pattern of granulocyte numbers in the exudate showed a two-step appearance, different from that of earlier determinations in soft tissue. A comparison between the calculated rates of granulocyte immigration and the total number of granulocytes present in the exudate at different times indicated that all immigrated cells survived in the chamber for the entire observation period of 6 days.
