[The cytopathic and cytogenetic sequelae of chronic inhalational exposure to formaldehyde on female germ cells and bone marrow cells in rats].

A study was made of cytopathological and cytogenetic effects of formaldehyde chronic inhalation, in doses 0.5 and 1.5 mg/m3, on the female rat's germ and marrow cells. The harmful effect of formaldehyde on germ cells (according to the patterns of early embryogenesis) is noted under the dose 1.5 mg/m3 only, while the reliable clastogenic and cytogenetic effects on the marrow cells were revealed even in the dose 0.5 mg/m3. It is concluded that the differences between effects of small doses of formaldehyde on different cell systems were evidently caused by the specific cell dynamics of these systems.
