Genetic structure of the population of wild-growing vines of the Utrish Nature Reserve

Grapes are one of the most common agricultural crops in the world. Currently, the analysis of genotypes directly at the DNA level is considered to be the most accurate method for studying the plant gene pool. The study of wild vines and ancient varieties in various regions of viticulture is an important direction of research in this field. The purpose of this work was to study the population of wild grapes growing on the territory of the Utrish Nature Reserve on the Black Sea coast of Krasnodar Region. The territory of the reserve is of interest as it is a site of ancient settlements, and the environmental conditions are suitable for the growth of wild grapes. During the survey of the territory, 24 samples of wild grapes were found, which were described according to the main morphological characteristics and analyzed by the molecular genetic method. The found vines were genotyped using 15 DNA markers, including nine commonly used for DNA fingerprinting (VVS2, VVMD5, VVMD7, VVMD25, VVMD27, VVMD28, VVMD32, VrZAG62, VrZAG79) and VVIb23, which allows determining hermaphrodite and dioecious vines. Statistical processing of microsatellite loci polymorphism data was carried out using the GenAlEx 6.5 program. The genetic relationships of the studied vines were evaluated using the PAST 2.17c program. The samples were found to be morphologically and genetically polymorphic. The number of alleles identified in the sample varied from 5 to 18 and averaged 8 alleles per locus. Statistical processing of DNA analysis data made it possible to identify two genetically different populations among the wild discovered vines. An assessment of genetic similarity of the found vines with some local varieties of geographically close viticulture regions, rootstocks and representatives of Vitis sylvestris from other territories was made. One of the populations found in the Utrish Nature Reserve is close to a number of V. sylvestris genotypes, the DNA profiles of which are presented in the Vitis International Variety Catalogue.

[Aneurysm of the gastroduodenal artery in a female patient with the postcholecystectomy syndrome (a clinical case report)]

Aneurysms of visceral arteries appear to belong to rare and potentially lethal vascular diseases. The most important role in the aetiology of aneurysms of the gastroduodenal artery is plaid by either acute or chronic pancreatitis. The article deals with a clinical case report concerning a saccular partially thrombosed aneurysm having developed in a 77-year-old woman presenting with the postcholecystectomic syndrome and detected on ultrasonographic examination of the abdominal-cavity vessels. Timely radiodiagnosis (SCT angiography of abdominal cavity vessels), adequate and timely performed endovascular occlusion of the cavity of the aneurysm with metal spirals performed in a timely manner made it possible to attain a favourable outcome. Little is known regarding the understanding of the aetiology and lack of full clarity in therapeutic approaches to aneurysms of visceral arteries predetermine the necessity to continue collecting clinical case reports concerning this rarely encountered vascular pathology in order to generalize and work out an appropriate therapeutic-and-diagnostic algorithm.

[Clinical and morphological substantiation of SMC-peloidotherapy for the management of duodenal pathology]

This study included 112 patients presenting with duodenal ulcer disease and 65 ones with chronic duodenitis treated with the use of sinusoidal modulated current (SMC) electrophoresis in combination with peloidotherapy (peat muds of the Uva health resort, Republic of Udmurtia). This treatment was shown to produce positive effect on the proliferative activity of duodenal epithelium.

[Efficacy of SMC-electrophoresis of peat mud in primary chronic duodenitis]

Sinusoidal modulated current (SMC) electrophoresis of peat mud was used as monotherapy of primary chronic duodenitis in Uva sanatorium. A total of 65 patients with primary chronic duodenitis received SMC electrophoresis of peat mud diluted with distilled water. The effect was followed up with fibrogastroduodenoscopy and target biopsy of duodenal mucosa with further study of its morphological structure and element composition, acid-producing function of the stomach, hormonal profile, collagen metabolism. Positive changes were observed in clinical-endoscopic and morphological picture of the disease which is explained by favourable shifts in hormonal status and normalization of collagen metabolism in duodenal mucosa.

[Principles of differential diagnosis and strategy in acute intestinal obstruction]

Intestinal obstruction is diagnosed as one of two kinds--small intestine and large intestine obstruction. They differ in etiology of the obstacle, pathogenesis and degree of clinical picture. The cause of the small intestine obstruction in patients having laparotomy in medical history is the formation of commissures. In patients with intact abdomen the cause of low obstruction was torsion and intussusception, the cause of high obstruction was the obturation with a bile calculus and a foreign body. Causes of the large intestine obstruction were obturation with a tumor and torsion. Napalkov's test is expedient but when suspecting the small intestine obstruction. Conservative treatment is possible in commissural small intestine obstruction (12-24 h) and in large intestine obturation obstruction (not longer than 2h).

[Dynamics of the morphofunctional status of digestive organs in patients with chronic gastroduodenitis during monotherapy with sulfate sodium-calcium mineral water]

The authors describe morphofunctional changes in gastroduodenal tract in patients with chronic gastroduodenitis. Some of them have previously undergone laparoscopic cholecystectomy for cholelithiasis. Balneotherapy with mineral water "Uvinskaya" has a good effect in the above disease and therefore is recommended for prevention and treatment of patients with chronic gastroduodenitis as well as for prevention of repeated cholelithiasis after cholecystectomy.

[The treatment of patients with chronic cholecystitis and hypomotor biliary dyskinesia at a sanatorium]

Efficacy of spa treatment with moderately mineralized mineral water from the spring utilized by balneological sanatorium Uva in the Republic of Udmurtia was studied in 524 patients with chronic atrophic gastritis concomitant with chronic cholecystitis and hypokinesia of the biliary ducts. Drinking water proved beneficial for hepatobiliary tract, clinical symptoms regressed, the ability of the gallbladder to concentrate and expel bile improved.
