Autophagy in placentas from acidotic newborns: an immunohistochemical study of LC3 expression.

abstract：:The permeability of the rat placenta at 21 days' gestation (term is 23 days) has been measured with fetuses intact in situ and by perfusion of the fetal circulation. Intact measurements were made by removal of fetuses at known time intervals after injection of radioisotopes to the anaesthetized mother and measurement ...
