Opis:: Studies were undertaken to evaluate by parasitological techniques the course of intestinal and muscular invasions in mice infected with Trichinella spiralis and treated with TFX-Thymomodulin (TFX-Th). Studies were conducted on 120 mice of BALB/c and SWISS strains, infected each with a mean invasive dose of 300 T. spiralis larvae. TFX-Th (Thymoorgan GmbH Pharmazie Co. KG, Vienenburg, Germany) was administered subcutaneously at 30 mg/kg body weight. Depending upon duration of TFX-Th administration and stages of intestinal and muscular invasions, three experiments were distinguished in the study. The results indicated that TFX-Th promoted eradication of larvae from muscles, whether administered at the early of the late stage of T. spiralis invasion.

Opis:: The pathomechanism of Helicobacter pylori action upon gastric mucosa and its role in the pathogenesis of gastritis have not been fully elucidated. The aim of this study was to evaluate the most prevalent lymphocyte subpopulations of the gastric mucosa in gastritis in children, as well as to evaluate the expression of Fas and Fas ligand receptors (FasL), periapoptotic markers of gastric mucosa lymphocytes before and after H. pylori eradication. Forty nine patients aged 6 to 17 years, investigated due to chronic abdominal pain, were studied. The obtained tissue samples were analysed by immunohistochemistry. Different lymphocyte subsets were quantified on the basis of surface antigen expression (CD3, CD4, CD8, CD20), secreted cytokines (IL-4, IL-6, IFNγ) and Fas and FasL proteins in the gastric mucosa. B and T helper lymphocytes were found to play a major role in the inflammatory infiltration in the gastric mucosa in children during H. pylori infection. Their expression was found to decrease after eradication. The enhanced expression of Fas receptor on lymphocytes before treatment and a decrease of this expression after eradication of H. pylori were shown. It was demonstrated that there is a correlation between CD4 and Fas receptor expression that may induce apoptosis of the helper lymphocytes in infected children.

Opis:: Malignant lymphoma is one of the most common malignant tumours occurring in dogs. Fine needle aspiration biopsy (FNAB) is an excellent, specific diagnostic procedure used to assess pathological processes in lymph nodes. The aim of the present study was to conduct a cytopathological analysis of lymphoma in dogs and to analyse some epidemic aspects of occurrence of lymphoma in 100 dogs using Giemsa stained slides. Samples were obtained by fine needle aspiration biopsy, fine needle non-aspiration biopsy, lymph node impression smears and by examination of body cavity effusions. The determination of the type and subtype of tumour was made on the basis of the updated Kiel classification adopted for dogs. Based on cytopathological analysis, the lymphoma was diagnosed in 100 dogs: 44 were female and 56 male. The animals’ age ranged from 1.5 year to 15 years (median: 7.5 years), the animals were of different breeds (72% of all dogs belonged to 28 different breeds) and crossbreeds (28%). In 29% of dogs the regional or general lymphadenomegaly was the only clinical sign observed, in remaining cases (71%) at least one abnormality connected to lymphoma was found. Among all diagnosed lymphomas, high-grade lymphomas were more prevalent (86% of all cases) than low-grade lymphomas (14% of all cases). The possibility of boxers having a predisposition to T cell lymphoma development could be also suspected.

Opis:: The aim of the study was to determine whether treatment with recommended doses of meloxicam or flunixin had an effect on the apoptosis of peripheral blood T lymphocytes in calves. The study was carried out on 4-5 months old calves (n = 24, 8 per group). Experimental animals were injected subcutaneously with a single dose of 0.5 mg . kg-1 of meloxicam or intravenously with 3 doses of 2.2 mg . kg-1 day-1 of flunixin. The non-treatment animals served as control. Blood samples were taken at day 0 and at days 1, 2, 3, 5, 7 and 14 after the first NSAIDs injection. Apoptosis was determined by flow cytometry using Annexin V-PE/7-AAD staining. The kinetic analysis of apoptosis in the total lymphocyte population, as well as in the CD4+ and CD8+ subsets did not reveal significant differences in the frequency of early apoptotic cells between control and experimental groups throughout the period studied. Although, 24 h after administration of the first dose of NSAIDs, late-stage apoptosis/necrosis was significantly increased in the total lymphocyte population (the meloxicam group), as well as in the CD4+ (the meloxicam group and the flunixin group) and CD8+ (the flunixin group) subsets of T cells. However, this disturbance was transient, relatively poorly expressed and, thus, unlikely to be of clinical significance. Our results indicate that the use of meloxicam or flunixin in accordance with the recommended dosage regimen in cattle do not have a clinically significant influence on apoptosis of peripheral blood T cells.

Opis:: The paper describes the immunological response in the matter of percentage of T cells (receptor CD5+) and subpopulations (Th with receptor CD4+, Tc/Ts with receptor CD8+, T with receptor CD25+) and B cells with receptor CD19+, as well as the percentage of apoptotic granulocytes and lymphocytes, in rabbits experimentally infected with the Hagenow strain of the RHD virus. The material chosen for the experiment is special, as among all strains of RHD virus, there are only two strains which carry the variable haemagglutination capacity of red cells. The results of the study show that the Hagenow strain gives an untypical picture of T and B lymphocytes, whereas the results in inducing apoptosis seems to corespond with previous data, confirming the inclusion of apoptosis from 4 h p.i. and the intensity of the phenomenon being higher in granulocytes.

Opis:: WC1+ cells in cattle exhibit both regulatory and effector activities. However, it has not been elucidated whether they are so plastic that both activities co-exist in one cell or there are separate subpopulations of effector and regulatory cells. Since the production of IFN-γ and IL-10 seems to be related to WC1+ cells’ effector and regulatory function, respectively, the main aim of this study was to determine whether those cytokines are produced by separate subpopulations of WC1+, or are co-produced by the same cells. Due to increasingly frequent emphasised role of consumption of IL-2 in the mechanism of suppressor action of mouse CD25+CD4+ T regulatory cells, expression of the receptor’s α chain for interleukin 2 (CD25) on WC1+ lymphocytes has been evaluated. An average of 5.21% of WC1+ cells obtained from PBMCs of 12-month-old heifers show constitutive expression of the CD25 molecule, with CD25highWC1+ and CD25lowWC1+ cells accounting for 1.05% and 4.10% of WC1+ lymphocytes, respectively. For detection of intracellular cytokine production, PBMCs were stimulated with concanavalin A. Both IFN-γ- and IL-10-producing cells within the CD25-WC1+ and CD25+WC1+ subpopulations were mainly separate subpopulations. The average percentage of IFN-γ+IL-10-, IFN-γ-IL-10+ and IFN-γ+IL-10+ cells among CD25-WC1+ lymphocytes was 4.03%, 2.67% and 0.51%, respectively. A positive correlation was observed between the presence of the CD25 molecule on WC1+ lymphocytes and production of IL-10 and TGF-β, because the average percentage of IFN-γ-IL-10+ and IFN-γ+IL-10+ among CD25+WC1+ lymphocytes was 3 and 4.5 times higher as compared to the corresponding cells in the CD25-WC1+ subpopulation, whereas the percentage of IFN-γ+IL-10- cells in both the subpopulations was not significantly different. The percentage of TGF-β+ cells within the CD25+WC1+ subpopulation was 2.72 times as high as that of CD25-WC1+ lymphocytes. Therefore, with respect to the production of IFN-γ, IL-10 and TGF-β, CD25+WC1+ lymphocytes turn out to have a more suppressor profile than CD25-WC1+.

Opis:: Psoriasis vulgaris is a common, worldwide autoimmune skin disorder characterized by T-cells mediated hyperproliferation of keratinocytes. The feature of T-cells arbitrated psoriatic lesions is the epidermal infiltration of oligoclonal CD8⁺ T-cells and also of CD4⁺ T-cells in the dermis. Psoriatic scratches are identified by red and enlarged lesions along with silver whitish scales. In this article, we propose a mathematical model for psoriasis, involving a set of differential equations, concerning T-cells, dendritic cells and epidermal keratinocytes. We introduce T-cell proliferation in the system, where T-cells are generated through expansion of accessible CD4⁺ T-cells from precursors. We are interested in observing how the cell biological system develops through T-cell proliferation in presence of control with respect to T-cells and keratinocytes. We study the model in both implicit and explicit ways and measure the effect of drug on the system through impulsive drug therapy.
