[Morphological features of oesophagogastric junction mucosa in children with gastroesophageal reflux disease].

In present work we studied the morphological features of the esophageal mucosa in 63 children with gastroesophageal reflux disease (GERD). The biopsies were taken at level of 3 cm above a Z-line and at level of 0.5-1 cm above a Z-line.

[Clinical and anatomical features of the middle ear in the premature infants at different gestational time].

The objective of the present study was to analyse anatomical features of the middle ear in the premature infants of different gestational age. Materials from 100 still-born and live-born babies (200 temporal bones) were available for the investigation. The study has revealed a number of distinctive clinical and morphological peculiarities in the structure of tympanic membranes in both the prematurely born infants depending on the gestational age and in the full-term babies.

[Morphological features of the esophagogastric transition zone at fetuses and newborns].

Morphological research of the esophagogastric transition mucosa at 35 fetuses and newborns was done. The esophagogastric transition was lined by high columnar epithelium and mucos glands. At fetuses of 22-24 week gestational age studied zone didn't have any glands.

[A method for assessing bacterial microflora by fluorescence in situ hybridization].

The use of current diagnostic methods in a pathologist's practice, including the assessment of the bacterial microflora by the molecular microbiological technique fluorescence in situ hybridization is important and promising. The detection of bacteria and changes in the microbial flora makes it possible to clarify the nature of found morphological changes and to expand the diagnostic value of a postmortem study.

[Morphological changes in esophageal mucosa in children with overweight].

In present work we studied the morphological features of the esophageal mucosa in 63 children with endoscopic diagnosis of the distal esophagitis having overweight and normal weight of a body. The biopsies were taken at level of 3 cm above a Z-line and at level of 1 cm above a Z-line. Dystrophic and dysregenerative changes were revealed at the majority of children and half of children had inflammatory changes of the esophageal mucosa regardless of weight of a body.
