An enzyme-histochemical, ultrastructural and morphometric study on fetal and neonatal rat diaphragms.


The organogenesis of the rat diaphragm was studied with enzyme-histochemical, ultrastructural and morphometrical methods. 18 to 20 and 22 day in utero diaphragms were examined as well as 2-8-14 and 25 day old ones, in order to determine the age related changes in the diameter and the percentage of muscle fibers and mitochondria. In all examined ages… (More)
