Abstract

Volume density of respiratory organs was studied in vitro in newborn babies at different age of gestation (abort, immature, premature and mature) using stereometric method. The total of 23 cases was subject to this study. The respiratory organs (trachea, lungs) were taken from autopsies of newborn babies exited from different causes. For this purpose the tissues were fixed in formalin (10%) solution, cut serially in 7micro and 10micro slabs. Volume density of the respiratory system was assessed stereometricaly using Universal testing system Weibel M 42. We observed that volume density of epithelia, musculature and glands were proportionally present in the tracheal tissue. Cellular interstitial tissue is consistently increasing and corresponds to the developmental stages of the newborn babies. The density of tracheal ganglions is greater in premature ages of immature and premature newborns (p<0,05). Decreased number of ganglion cells is observed in mature ages (p<0,05). This is caused by intensive ramification of ganglions from serosa to deeper layers of trachea right to epithelium. Medium diameter of tracheal ganglions is greater in mature newborn babies and corresponds to developmental ages of babies.

Distributions of ganglion cells in the structure of tracheal tissue in live borne babies deceased after birth and fetuses exited in different weeks of gestations:
  1. Cholinereactivity well expressed in perichondrial mature ganglion containing 21 ganglion cells in mature babies (Indoxyl method for esterase; 650x).

  2. Ganglion cells in lamina propria of tracheal tissue with expressed choline reactivity, with dendritic and axonal extensions around tracheal glands in prematurely born babies (Indoxyl method for esterase; 400 x).

  3. Choline reactivity in smooth musculature tracheal ganglion in prematurely born babies, which contains 4 cells with oval appearance (Indoxyl method for esterase; 400 x).

  4. Tracheal ganglion cells arranged in the crown form with expressed choline reactivity in mature born babies (Indoxyl method for esterase; 1600 x).

  5. Ganglion cells in lamina propria of tracheal tissue with axonal extension (Indoxyl method for esterase; 400 x).

  6. Group of ganglion cells with perivascular arrangement in tracheal tissue in prematurely born babies (Indoxyl method for esterase; 650x).
