[The study of a diagnostic model of mucogingival deformities using high-frequency ultrasound dopplerography].

Objective: The aim of the study is to increase the effectiveness of diagnostics of microhemocirculatory changes in periodontal tissues in anatomical and functional disorders of the mucogingival complex, based on the use of the method of discriminant analysis of ultrasound opplerography.

Material And Methods: 187 patients aged 18-44 years (young age according to WHO) were examined without concomitant somatic pathology with various variants of anatomical structures of the mucous-gingival complex, which included an assessment of blood flow in periodontal tissues by ultrasound dopplerography at rest and during a functional test of the tension of the soft tissues of the upper and lower lip, cheeks using an opt-out. After qualitative and quantitative analysis of dopplerograms, an automated assessment of the microhemocirculation of the studied structures was performed, identifying differences between groups using step-by-step discriminant analysis with the study of several variables.

Multiple infection of amber Succinea putris snails with sporocysts of Leucochloridium spp. (Trematoda).

Amber Succinea putris snails were collected in the Leningrad Region (Russia). Some of them were infected with trematodes Leucochloridium paradoxum, Leucochloridium perturbatum and Leucochloridium vogtianum. One snail had triple infection with all these species.

[Microbiology of the buccal mucosa in elderly patients with general somatic diseases].

Sixty-two patients with cardiovascular, gastrointestinal, and endocrine diseases aged over 60 years and 27 healthy young people aged 16-18 years (controls) were examined in order to evaluate the qualitative composition and dissemination of oral microflora in elderly people with general somatic diseases. Microbiological study revealed changes in the qualitative composition and dissemination of the oral mucosa microflora, which depended on patient's age, disease, and treatment administered for somatic disease.
