About the Origin of the Family Allocreadiidae (Trematoda: Plagiorchiida).

The phylogenetic relationships established in the family Allocreadiidae by genetic methods suggest that the center of origin, distribution, and divergence of the studied family is, apparently, eastern regions of Laurasia (the territory of the modern Southeast Asia), from where these trematodes penetrated through the Amur paleomicrocontinent and Beringia to North America and further through Central America to South, as well as through Transbaikalia and Yakutia to the western part of Eurasia.

Harmful Parasitoses on the Russian Southern Far East under Climatic and Demographic Changes.

Progressive expansion of the most hazardous human parasitoses caused by trematodes, cestodes and nematodes has been found on the south of the Russian Far East. Decelerating expansion of the trematode Clonorchis sinensis, an agent of clonorchiasis towards the southern Primorye Territory from the Amur River basin, that began 10-15 years ago, was revealed. A prognosis was made on the activation of the natural foci of clonorchiasis and paragonimiasis. Circulation possibilities are discussed of the highly pathogenic trematode Pagonimus heterotremusar in the South Asian regional ecosystems. Our experiments showed that the freshwater gastropods of the Parajuga genus from the Amur River basin and those of Stenothyra genus from Primorsky Territory were resistant to this trematode infection. Nevertheless, this does not exclude the possibility of this parasite penetration into the Far East region via infection of the local gastropods of other genera.

Evaluation of the Applicability of the Comparatory Method for Species Diagnosis of Unionidae (Bivalvia) by Genetic Analysis.

Five genetically distant groups of mussels possessing high intragroup homogeneity were identified among 65 specimens of 14 East European Unionidae "comparatory species" by genetic analysis of nuclear and mitochondrial markers. By shell morphology other than the shape of the convex contour of the shell, the identified groups correspond to five "taxonomic species" according to Zhadin's classification. The use of the comparatory method for Unionidae species identification is unjustified.

[Role of viruses with oncogenic potential and their associations in oncogenesis in maxillofacial area].

The potential role of viruses with oncogenic potential such as human papilloma virus, cytomegalovirus, Epstein-Barr virus, herpes simplex virus type 1 and 2, herpes virus type 6, in the development of benign and pre-cancerous tumors of maxillofacial region was assessed in the study. We examined 26 patients with tumors in maxillofacial region (skin and mucosa) using molecular-genetic and histological studies of surgically removed neoplasms removed. In 53.8% of the examined samples DNA of Epstein-Barr virus, herpes virus type 6, herpes simplex virus type 1, or cytomegalovirus and in 35.7% of them the association of the above mentioned viruses were detected. It may confirm their relation with the development of benign, precancerous and malignant neoplasms in maxillofacial region.

[Microbiocenosis of major biotopes of the oral cavity in patients with tongue carcinoma during complex treatment].

The composition of the microflora in three biotopes of the oral cavity was examined in 36 patients with tongue carcinoma before chemotherapy, one - two weeks after two courses of chemotherapy and before gemiglosseklomiya. The oral dysbiosis was revealed in patients before antitumor therapy. The opportunistic and pathogenic bacteria in concentration more than 4 lg CFU/cm² were dominant in microbiocenosis of oral cavity. Most of the isolated microorganisms were capable of maintaining the inflammatory process by secreting oral enzymes and toxins. The microflora formed normobiocenosis in oral cavity after two courses of chemotherapy. The pathogenic potential of selected microflora in patients after preoperative radiotherapy before surgery was more pronounced than the microflora of healthy people, and also in patients prior to treatment. Dysbiosis of III degree was detected in oral cavity of patients with tongue carcinoma before gemiglosseklomiya. requiring correction for the prevention the postoperative complications.

[Does the comparator method has a future in diagnosing large bivalves (Bivalvia: Unionida)?].

It is shown that the contours of the frontal sections of valves in shells of different size of the same species run through different parts of the valve. A new modification of the comparator method is proposed, which allows studying the shape of the maximum convex contour of the cross-section of the shell.

[Integral assessment of endogenous intoxication in patients with phlegmons of maxillofacial area].

The study assessed the correlation of red blood cells structural and functional disorders as a result of tissue metabolism changes and accumulation of final and intermediate metabolic products in association with microbial toxins, as well as changes of plasma general antioxidation capacities with clinical manifestations and degree of endogenous intoxication syndrome in patients with widespread phlegmons of maxillofacial area. The red blood cell structure served as an indicator of all biological membranes condition. The correction of red blood cells structure was achieved by administration of membranoprotective antioxidants.
