The effect of a single intragastric injection of 1,2-dibromoethane was investigated in kidneys of male Wistar rats. DNA synthesis as measured by the incorporation of tritiated thymidine was found to be approximately 5 times greater than that of controls 20-30 h after treatment. DNA synthesis was followed by a striking increase in the mitotic activity with a maximum at 30 h. The labeling and mitotic activities, after an initial increase, fell rapidly 48 h after treatment even though they were still higher than those of control animals. 1,2-Dibromoethane-induced cell proliferation is not a regenerative response because at the dose used in this study, no tubular necrosis was observed by histologic examination.

Abstract
The effect of a single intragastric injection of 1,2-dibromoethane was investigated in kidneys of male Wistar rats. DNA synthesis as measured by the incorporation of tritiated thymidine was found to be approximately 5 times greater than that of controls 20-30 h after treatment. DNA synthesis was followed by a striking increase in the mitotic activity with a maximum at 30 h. The labeling and mitotic activities, after an initial increase, fell rapidly 48 h after treatment even though they were still higher than those of control animals. 1,2-Dibromoethane-induced cell proliferation is not a regenerative response because at the dose used in this study, no tubular necrosis was observed by histologic examination.
