Mitosis dynamics in bone marrow of continuously irradiated rats

Abstract

Values were investigated of the mitotic index (MI) and the metaphase/prophase ratio (M/P) in rats continuously irradiated with daily doses of 0.5 to 82.5 R. Changes resulting from the continuous irradiation were manifest in two stages, viz.: 1. adaptation stage up to the 30th day of irradiation - the values fluctuated considerably; 2. steady-state stage since the 30th day till the end of irradiation - the values stabilized at a certain level. During the adaptation stage, MI values decreased till the 25th day; then they increased and remained at a certain lower value till the end of the experiment. M/P values showed a considerable variability between the 5th and the 25th days and a significant increase in the steady-state stage, mainly at higher dose rates.
