[Restitution of bioactive ceramic material "Syntekost" by a newly evolved bone in experiment].

Peculiarities of reparative processes of bioactive ceramic material "Syntekost", as well as reaction of structures of internal ear on these material, transplanted on osteal bulla in guinea pigs for experimental model of antromastoidotomy creation, were studied up. The signs of its resorbtion were mild, and these processes not always paralleled the osteal tissue evolvement. A newly formed osteal beams were observed up to 90-th day.

[Investigation of adhesive properties of polypropylene net prosthesis "ESPERA"].

Adhesive towards the cells properties of three polypropylene net prostheses (PNP), manufactured by "Espera", with the slots size 1 x 1 mm, 2 x 2 mm, 2 x 4 mm and one specimen (the slot diameter 1 mm) on the oxycellulose background, were tested for prognostication of hernioplasty results, using nonresorbable PNP. The adhesion degree and peculiarities of cellular line, obtained from embryonal kidney of pig, put on the tested nets specimen in conditions of cultivation during 5 - 10 days were estimated, using inverted microscope in regime of phasic contrast. The data obtained witness the lowered cellular adhesion towards PNP "Espera" without oxycellular background.

[Inhibition of the stellate cells using lisinopril and lovastatin for prophylaxis of pancreatic stump fibrosis after performance of distal resection in a model of chronic alcoholic pancreatitis].

Complex application of lisinopril (inhibitor of angiotensin-converting enzyme) and lovastatin (inhibitor of HMG-CoA reductase) inhibits pancreatic fibrosis in the rats, having alcoholic chronic pancreatitis after distal pancreatic resection (DPR). Lisinopril and lovastatin were injected to the rats after DPR in dose 10 mg/kg during 3 weeks. Immunohistochemical markets, such as alpha-smooth-muscle actin (alpha-SMA), desmin, glial fibrillary acidic protein (GFAP), vimentin, and expression of matrix metalloproteinase-1 (MMP-1) as well as inhibitor of matrix metalloproteinase-2 (TIMP-2) were detected for estimation of therapeutic impact on activity and quantity of stellate pancreatic cells.

[Inhibition of pancreatic stellate cell activation by lisinopril for prevention fibrogenesis in experimental chronic alcoholic pancreatitis].

Lisinopril (angiotensin-converting enzyme inhibitor) attenuates fibrotic changes in pancreas after distal pancreatectomy in rats with experimental alcohol induced chronic pancreatitis. Lisinopril was administered after distal pancreatectomy in rats with experimental alcohol induced chronic pancreatitis. The animals were treated with lisinopril at the dose of 10 mg/kg body weight per day for 21 days after operation.

[Creation of models of incomplete external lip-like large bowel fistula in experiment].

The method of experimental simulation of the incomplete external lip-like large bowel fistula creation was elaborated on experimental animals for studying of possibilities forapplication of hyperthermic methods of the fistula channel obliteration and disinfectioning of the neighboring anterior abdominal wall tissues. There were studied up microflora and bacterial seeding of the large bowel contents in the zone of a fistula exit as well as dynamics of changes of inflammatory processes, occurring in tissues of anterior abdominal wall, neighboring the external orifice of a fistula channel.
