| Abstract | ||
| The current study aims to describe the normal anatomical structures of neonate lungs )weights, volumes and dimensions( as well as the architectural histology of structure In this study, 20 neonate cadavers collected with age ranging from 0-28 days, all these cadavers were collected from the Forensic Medicine in Baghdad and Kirkuk. Following dissection, the organ weight and gross metrical measurements were measured. Histological study was done on all cadavers enrolled in the study using Periodic Acid Schiff )PAS( Stain The results showed that the weight of neonatal lung was increased proportionally with age and the highest mean weight, volume and dimensions of lungs were found in neonates whose in the age group 22-28 day. The study revealed that dimensions of the left lungs were slightly more than those of right lungs especially in the age group 22-28 days. The study indicated that the volume of neonatal lungs were increased proportionally with age and the highest mean volume of lungs was found in neonates whose in the age group 22-28 days 50.03 cm3. The tunica media of the blood vessels of small and medium sized were well demonstrated of the thickness of alveolar walls also were obvious with inflammatory cell infiltration, the interstitial C.T. also associated with presence of smooth muscle cells, surrounded by segments of hyaline cartilage which are demonstrated easily, the lumen of bronchus appeared containing exudate, around the lung was containing with collagen bundle the elastic fibers. The basement membrane of the pulmonary blood vessels was demonstrated well by PAS which appeared thickened and the lumen of blood vessels was filled with blood serum and individual inflammatory cell. The interstitial C.T. around the blood vessels were containing dust cell with lymphocyte infiltration. . | ||
