Assessment of Selected Surface and Electrochemical Properties of Boron and Strontium-Substituted Hydroxyapatites.

Tissue engineering is an interdisciplinary field of science that has been developing very intensively over the last dozen or so years. New ways of treating damaged tissues and organs are constantly being sought. A variety of porous structures are currently being investigated to support cell adhesion, differentiation, and proliferation.

[Morphological changes of the esophagus in adenocarcinoma and squamous cell carcinoma].

Purpose: To study the micro-topography of the abdominal wall of the esophagus and give it a quantitative characterization of tumor pathology of the esophagus.

Methods: The study was performed using morphological methods: 1 anatomical dissection; 2 gistotopographical method with coloring of gistotopogramms with hematoxylin-eosin and Van Gieson; 3 Morphometry of macro and microstructures of the esophagus. Operating studied material from 15 patients who over the tumor lesion was performed resection of the lower third of the esophagus and the upper part of the stomach.

[Experimental morphological basis of the application of microsurgical intestinal suture under the conditions of inflammatory pathology of gastro-intestinal tract organs].

Experimental study of morphological peculiarities of intestinal wall and common bile duct wall healing using microsurgical sutures under the condition of peritonitis and cholangitis, was performed in 112 dogs. It was shown that the microsurgical suturing of intestinal wall and common bile duct wall affected by the inflammatory process, created the favorable conditions for wound healing. During the recovery period, the thickness of all the layers of the intestinal wall decreased, the disturbances of the normal fibrous structure and the vascular reaction of the submucosa were reduced.

[The histotopography of the main and lobar bronchi as an anatomical basis for microsurgical bronchial suture].

Histotopographical study of the main and lobar bronchus was performed from 15 corpses of people aged from 23 to 62 who did not die from lung pathology. The peculiarities of histotopography and their possible application in microsurgical operations on bronchus were shown.

[Isolation of a cytopathogenic rotavirus from calves].

A cytopathic rotavirus was isolated from calves with symptoms of diarrhea and underwent 15 passages in bovine embryo kidney cell culture. The specificity of the isolate was confirmed by the neutralization test, immunofluorescence, electron microscopy. The CPE of the isolated in bovine embryo kidney cells was similar to that of the reference strain.
