Cytological parameters of buccal epithelium for the diagnosis of functional state of man

The past twenty years have seen dramatic growth and consolidation in DHMO and PPO segments of the dental benefits industry. Purchasers and patients are becoming more vocal in their demands, primarily for controlling costs. It is predicted that emerging trends will include greater emphasis on quality (and its relationship to cost) and on dental practice management companies. It is less clear what role organized dentistry will play in these changes.     

Bile duct decompression and immune correction in the surgical treatment of mechanical jaundice of non-tumor origin

The aims of the study were: 1) to determine optimal duration of bile ducts decompression (BDD) and terms for radical operation performance; 2) to define criteria of effectiveness of the decompression and readiness of the patients for radical surgical treatment; 3) to analyze disorders in liver function and indices of immunoreactivity in relation to the method and duration of BDD; 4) to develop method of immunocompression for increase of effectiveness of BDD. The patients were divided in to three groups. 28 patients of group 1 had duration of jaundice up to 5 days and bilirubinemia up to 86.3 +/- 3.12 mmol/l. 35 patients of group 2 jaundice up to 15 days and bilirubinemia up to 184.7 +/- 4.22 mmol/l. In group 342 patients had bilirubinemia up to 124.4 +/- 2.23 mmol/l and cholangitis. External decompression of bile ducts quickly promotes restoration of drainage function of the liver and normalization of biochemical indexes. Restoration of immunological indexes in groups 2 and 3 is progressing slowly and demands immunocorrection. Indexes of immunoreactivity and biochemical data of functional status of the liver could serve as criteria of effectiveness of bile ducts decompression and possibility of radical surgical treatment. Regional immunocorrection is indicated for the patients' preparation for surgery.     

Inactivation and stabilization of urokinase fibrinolytic activity in vitro

The first and second internal transcribed spacers (ITS1, ITS2) as well as the intervening 5.8S coding region of the rRNA gene were characterized in eight Babesia canis isolates of differing geographic origin, vector specificity, and pathogenicity to dogs. The genotypes determined by sequencing segregated into three clearly separated groups close to or near the species level and correspond to the previously proposed subspecies B. canis canis, B. canis vogeli, and B. canis rossi. The three genotypes can be distinguished by Sau96I digestion of the polymerase chain reaction (PCR)-amplified rDNA target.     

The administration of peflocine (pefloxacin) in the treatment and prevention of surgical infections

The results of treatment of 23 patients with pefloxacin, administered because of the infectional complications in surgery development (1 group), and of 11 patients --for the infection development prophylaxis (2 group) were discussed. In the first group the recovery was noted in 83.3%, and significant improvement of condition--in 16.7% of patients. In the second group the infectional complications in postoperative period were absent.     

Study of pathogenetic mechanisms of intoxication in patients with anaerobic non-clostridial infection

Pyoinflammatory diseases continue to be one of the most topical problem of modern medicine. Anaerobic non-clostridial infection is essential in the etiological pattern of pyoinflammatory diseases. Its specific feature is early developed severe intoxication. The authors have developed laboratory criteria for evaluating the degree of intoxication in patients with anaerobic non-clostridial infection, which are based on chromatographic determination of the concentrations of specific metabolic products, such as volatile fatty acids and toxic metabolites of the phenol group, in the patients' peripheral blood, which allows the detected disorders to be promptly corrected. The metabolic products of non spore-forming anaerobes, such as volatile fatty acids, are important pathogenetic factors since they inhibit the dynamic activity of platelets and the phagocytic activity of leukocytes in blood.     

Stabilization of omega-3-polyunsaturated acids in fat from Mallotus villosus (Osmeridae) by the nontoxic, sulfur-containing antioxidant CO-3

The stabilizing effect of the newly produced sulfur-containing antioxidant SO-3 on the fatty acid composition of fat obtained from Mallotus villosus was studied at various temperatures. In the absence of the antioxidant, omega-3 polyunsaturated fatty acids were found in the fish fat during 1 month at -18 degrees storage, although the content of these fatty acids was decreased 2-fold in this case. After addition of the SO-3 stabilizer to the fish fat at final concentration 0.2%, content of the omega-3 fatty acids was unaltered within 1 month at - 18 degrees, 10 degrees and was half decreased only at room temperature. Thus, nontoxic antioxidant SO-3 may be used to preserve preparations containing omega-3 polyunsaturated fatty acids.
