Comparison of myocardial apoptosis in 21 and 90 days after birth in pups induced by maternal long term ethanol consumption

This study was designed to assess and the cardiac apoptosis after the prenatal and early postnatal ethanol
treatment in pups.
Materials and Methods: Pregnant Wistar rats treated with ethanol 4.5g/kg BW once per day from the seventh day of gestation (GD7)
throughout lactation. Apoptotic cells, body wight, heart weight and their association on postnatal day 21 (PN-21) and postnatal day 90
(PN-90) was evaluated in male pups.
Results: The results showed that maternal ethanol consumption increased apoptotic cells, decreased heart weight, body weight, and
HW/BW after 21 and 90 days of birth compared with the controls. It has found more apoptotic cells in 90 days after births compared
with 21 days of age.
Conclusions: our findings revealed that maternal ethanol intake in pups decreased HW/BW ratio in part through apoptosis, which is
more predominant in 90 days of age
