[Quantitative study of the morphofunctional changes in the placenta of rats exposed to nicotine at various periods of pregnancy].
Administration of 2% nicotine to Wistar rats in doses of 1.5 and 5 mg/kg produced functional disorders of the placenta over the entire pregnancy. From the 14th to the 21st day it retarded pregnancy, which at a dose of 1.5 mg/kg was made for by the increased area of the trophoblast elements.
