title: Absence of mitotic reduction in regenerating rat livers exposed to ultrasound.
abstract: The frequency of mitotic cells in surgically stimulated rat livers in vivo was not affected by one- and five-minute exposures to 2.2 MHz ultrasound at intensities ranging from 60 to 16,000 mW/cm2. These results do not confirm Kremkau and Witcofski's report on mitotic reduction in rat liver similarly exposed to ultrasound.
