RESUMEN

Adult trematodes, morphologically similar to Haplosplanchnus pachysomus (Eysenhardt, 1829), were extracted from the intestine of Mugil cephalus Linnaeus, 1758, collected in the Black Sea basin. Morphological, morphometric and 28S ribosomal DNA (rDNA) partial sequence data were obtained for these trematodes following comparative analysis with previous data on this species. Worms from this study were morphologically identical to all previously reported H. pachysomus specimens from different locations. The results of the morphometric analysis indicated general similarity between H. pachysomus from the Black Sea and trematodes from Vietnam and Australia. Trematodes from the Black Sea and specimens from Spain were identical based on 28S rDNA partial sequences; however, these sequences differed from that of H. pachysomus from Vietnam and Australia by eight fixed substitutions. Overall, our results indicate that H. pachysomus from Spain and the Black Sea and from Vietnam and Australia can presently be considered as two cryptic species, one in Palaearctic and one in Indo-West Pacific regions. Our results provide a molecular base for including Haplosplanchnus purii in the genus Provitellotrema or to consider H. purii, P. crenimugilis and H. pachysomus within the same genus.

RESUMEN

The flow cytometry becomes a more and more largely applied technique. However, the sufficient novelty of technique has no worked-out standards of diagnostic of many diseases. The lacking of external control of quality promotes development of large variety of approaches to diagnostic of diseases and impossibility to compare the study results from different laboratories. The paroxysmal night hemoglobinuria is an acquired clonal disease characterized by proliferation of stem cells with partial or total loss of expression of glykosylphosphosphatidyl inositol anchor needed to conjugate a number of surface proteins. The flow cytometry is a basic technique of detection and monitoring of clone of paroxysmal night hemoglobinuria. The article presents the results of paroxysmal night hemoglobinuria testing of 8 patients in 6 independent laboratories using flow cytometry by standard protocol recommended by the International society of clinical cytometrists (ICCS).

RESUMEN

The percentage of T1 lymphocytes in the presence of the unchanged content of T2 cells were shown to be decreased in the peripheral blood of patients with pulmonary tuberculosis as compared with apparently healthy donors. In addition, the patients were found to have a significantly reduced quantity of CD80-expressing monocytes, the relative quantities of Th1 and Tc1 cells were directly related to the count of CD80+ monocytes. It is suggested that decreased CD80+ cells is a cause of ineffective antigen presentation that results in a systemic reduction in the count of CD4+ and CD8+ cells producing T1 cytokines and in impairment of an effective specific T1 response.

RESUMEN

The study group included 21 patients with malignant melanoma stage II-IV, aged 25-67, and 25 patients, aged 28-68, (control) with stomach tumors stage I-IV. All patients received individually-tailored hypnosis. Our newly-developed methods used batteries of suggestive images to deal with non-psychotic disorders and to map out strategies to support immunocompromised patients. In group 1, suggestion stimulated the "devouring" effect of the "patroling" cells. Quantitative and qualitative characteristics of immunocompetent cells of peripheral blood were assessed by flow cytometry, immuno-enzymatic analysis and other procedures to evaluate immunological status. Correlation analysis of data on group 1 identified 7 negative coefficients (p < 0.05 and p < 0.01) exactly in the monocytic macrophageal link thus suggesting the modulating effect of hypnosis. Our results support evidence available on the potential of hypnosis for cancer patient immunity and point for the first time to feasibility of differentiated targeting specific links of the immune system.

RESUMEN

Derivatives of the available plant triterpenes glycyrrhetic acid and betulin (betulin succinates and amides of betulonic and 18beta-glycyrrhetic acids containing fragments of long-chain amino acids and a peptide) were synthesized. The inhibitory action of these compounds on the growth of MT-4, MOLT-4, CEM. and Hep G2 tumor cells and their effect on the apoptosis of these cells were studied. It was shown that betulonic acid amides are more effective inhibitors of the tumor cell growth than the corresponding amides of glycyrrhetic acid. It was also found that betulonic acid amides containing fragments of caprylic, pelargonic, and undecanoic acids are more effective inhibitors of tumor cell growth than betulinic acid. The 17-dipeptide derivative of betulonic acid N-{N-[3-oxo-20(29)-lupen-28-oyl]-9-aminononanoyl}-3-amino-3-phenylpropionic acid exhibited the maximum inhibitory activity toward the tumor cells studied. Data on the induction of apoptosis in tumor cells by betulin derivatives at a concentration of 10 microg/ml were obtained by flow cytometry. The amides of betulonic acid proved to be the most effective inducers of apoptosis.

RESUMEN

We studied quantitative and functional parameters of bone marrow stem cells and mature lymphocyte population under conditions of impaired innervation in patients with injuries to the cervical and thoracic portions of the spinal cord. Our findings indicated the absence of deficiency of quantitative and proliferative potentials of stem cells and demonstrated intact subpopulation structure of mature lymphocytes and T-cell proliferative activity similar to that in donors. The content of CD34+ cells in patients did not differ from that in donors. The percentage of CD34+CD38- hemopoietic stem cells was elevated in patients, presumably due to increased proliferative activity of hemopoietic stem cells. The possibility of derivation and in vitro culturing of fibroblast-like cells with mesenchymal stem cell phenotype was demonstrated.

RESUMEN

AIM: To analyse the results of diagnosis and treatment of patients with aquired aplastic anemia (AA) in one center. MATERIAL AND METHODS: All AA patients, diagnosed and treated in one clinic in 1998-2005, were included in the trial. In severe and very severe AA (SAA/VSAA) the patients (n = 19) received combined immunosuppressive therapy (IST) with antithymocytic globulin (ATG) and cyclosporin A (CsA), in non-severe AA (NSAA) the patients (n = 9) were given monotherapy with CsA. Allogenic transplantation of bone marrow (alloTBM) was made in 4 young patients with SAA/VSAA. RESULTS: The diagnosis of AA was established in 33 patients (19 males and 14 females): NSAA in 9, SAA in 19, VSAA in 5, idiopathic--in 26, posthepatic--in 5, associated with pregnancy--in 2 patients. Age median was 20 years (13-53). The clone of paroxysmal nocturnal hemoglobinuria (PNH) was identified in 7 of 33 patients (21%), antigen HLA-DRB1 *15 in 6 of 11 patients (55%). In median of 26-month follow-up 31 patients (94%) were alive. In IST, complete or partial remissions were obtained in 88% patients. Median of the interval to achievement of transfusion independence made up 2.5 months. All the patients after alloTBM are in complete remission, chronic extensive transplant against host reaction was observed in one case. CONCLUSION: Introduction of updated protocols provides long-term survival of more than 80% AA patients. To optimize treatment outcomes, it is necessary to include newly diagnosed AA patients into ongoing multicenter studies.
