Wistar dams were injected subcutaneously, using a dosage of 1 mg nicotine/kg body mass/day, and treatment commenced 7 days after conception. The morphological and morphometric data were used to evaluate any damage or change in the structure of the trachea and lungs due to maternal nicotine exposure. Three techniques were used namely, light microscopy, scanning electron microscopy and transmission electron microscopy. Both morphological status and morphometric data were obtained from the sample animals.enMaternal nicotineMorphologyBiologyBiodiversityUniversity of the Western Cape
