[Effect of schemes second line quadruple therapy on interactions of some protective factors in gastric mucosal tissue in experimental ulcer].

Unlabelled: THE AIM OF INVESTIGATION: To study the effect of schemes second line quadruple therapy on the state of gastric mucosal barrier and NO formation in experimental ulcer.

Material And Methods: The study included 60 white male rats weighing 150-190 gr, mixed population. The effect of the standard second-line regimens on the content of the fractions of insoluble glycoproteins, on indicators of NO formation and anaerobic glycolysis in gastric mucosal tissue in experimental ulcer.

[The dynamics of bone defect healing after the implantation of collagen and hydroxyapatite complexes (an experimental morphological study)].

Healing of standard bone defects in the distal third of the femoral bone was studied in experiments on 48 rats. In order to repair the defect, colapol or a new composition with structurized collagen and hydroxyapatite powder and granulate KP-2 were used. Histological study showed that healing was optimal after repair with KP-2 composition: callus formed rapidly, as did the typical osseogranular complexes.
