BACKGROUND Nicotine is known to be associated with adverse effects in infants and children. It is concentrated in breast milk and is absorbed by the infant. The aim of this study was to investigate the effects on breast-fed rat pups of maternal nicotine exposure during lactation. METHODS In the experimental group (n = 6), nicotine was given to lactating dams (2 mg/kg/day) after delivery and continued for 10 days during lactation. Control animals (n = 4) received saline for the same duration. The suckling rats were weighed and killed on postnatal day 10, and samples were taken from the lung, liver, kidney, spleen and small intestine for histopathological examination. Superoxide dismutase (SOD), catalase (CAT) activities and malondialdehyde (MDA) levels were measured in the liver of the dam and the offspring. RESULTS Histopathological changes in the liver of the nicotine-exposed group showed portal inflammatory infiltrate, ballooning degeneration of hepatocytes, and focal necrosis in the parenchyma. Thickening of alveolar walls because of interstitial inflammation was noted in the lungs. Histopathological examination of kidney, spleen and small intestine tissue did not reveal any abnormality. In the experimental group, SOD and CAT activities were significantly decreased (p <0.001) but MDA levels were significantly increased (p <0.001) compared with the control group. CONCLUSIONS These results indicate that maternal nicotine exposure induces oxidative stress and causes detrimental histopathological changes in the lung and liver of lactating offspring.

UI MeSH Term Description Entries
D007774 Lactation The processes of milk secretion by the maternal MAMMARY GLANDS after PARTURITION. The proliferation of the mammary glandular tissue, milk synthesis, and milk expulsion or let down are regulated by the interactions of several hormones including ESTRADIOL; PROGESTERONE; PROLACTIN; and OXYTOCIN.

D009538 Nicotine Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke. Nicotine Bitartrate,Nicotine Tartrate

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D018384 Oxidative Stress A disturbance in the prooxidant-antioxidant balance in favor of the former, leading to potential damage.
