Average quantitative concentration of cotinine within the system pregnant woman-baby

The findings presented by the authors of this report contribute to the diagnosis of pathology of pregnancy i.e. they assess the influence of nicotine on the organisms of a mother and a new-born child, estimated by concentration of cotinine, the most important metabolite of nicotine. The mean proportional share of cotinine in the fluids and organs in the pregnant women smoking actively was as follows: urine 72.1%, amniotic fluids 14.3%, colostrum 8.9% and placenta 4.7%. The authors pay a particular attention to the "colostrum-milk way" in the mother-child relationship what is emphasized in this report.
