[Experimental contribution on the biochemical and morphological study of lung maturation in Wistar rats].
This is a research on the pulmonary normal maturity of a Wistar's Rat from the biochemic and morphological point of view. To do that we have chosen 3 lots of 5 rats each. The animals were sacrificed by killing them up to 15, 18 and 21 days of pregnancy. Then we have removed the amniotic liquid of each rat to know or study the creatinin concentration and the lecithin/sphingomyelin relation or report. To every foetus that we have got from every rat we have removed or extirpated the lungs to do a study under the optic microscope by using the hematoxilin-eosin together with the Fontana-Masson techniques.
