Effects of CCNU on hematopoiesis in rats
Cancer Treatment Reports
|March 1, 1979
Abstract:
The effect of orally administered CCNU on proliferating and cytokinetically "resting" bone marrow cells was studied in rats. The resting bone marrow cells were selectively labeled with 3H-thymidine by the "complete 3H-thymidine labeling method." The results show a reduction in the number of absolute bone marrow cells to about 40% of the original value in 3 days. Regeneration was completed only after 22 days. No difference was found in the destructive or the regenerative pattern of CFU-C, myelopoietic, erythropoietic, lymphatic, or megakaryocytic cells. Resting and proliferating cells of the bone marrow were equally affected by CCNU.
