Avaliação dos parâmetros hematológicos e imunofenotípicos de pacientes com doenças linfoproliferativas crônicas no Rio Grande do Norte

Chronic lymphoproliferative disorders (DLPC) are lymphoid system diseases characterized by the abnormal proliferation of mature lymphocytes that affect B cells, T lymphocytes and NK cells. The aim of the study was to demonstrate the relevance of immunophenotyping by flow cytometry in patients with prolonged lymphocytosis and / or cytomorphological changes compatible with lymphoproliferative diseases. In this study 460 patients (244 men and 216 women) with DLPC were evaluated. Were analyzed by flow cytometry with a panel of monoclonal antibodies consisting of CD3, CD4, CD5, CD8, CD10, CD19, CD22, CD23, CD25, CD38, CD45, CD16/CD56, and HLADR heavy and light chains of immunoglobulins. It also examines information regarding age, gender of patients and laboratory data as leucocytes, cytomorphological analysis, platelet count and hemoglobin determination. The results showed 398 cases of chronic lymphoproliferative disorders and 62 of DLPC B cell lymphoproliferative diseases T. B showed the following distribution : 253 cases of chronic lymphocytic leukemia (CLL), 42 cases of multiple myeloma ( MM ), 37 cases of lymphoma non - Hodgkin lymphoma in leukemic phase (NHL) , 17 cases of pro- B lymphocytic leukemia ( B -PLL), 15 cases of mantle cell lymphoma (MCL ), 12 cases of plasma cell leukemia ( PCL), 9 cases of lymphoma Burkitt (Linf B), 8 cases of leukemia villous cells ( LCV), 3 cases of splenic lymphoma with villous cells (LECV), a case of follicular lymphoma (LF) and a Waldenströn macroglobulinemia ( MW). The diseases source NK / T were 23 cases of peripheral T cell lymphoma (LCTP), 14 cases of T prolymphocytic leukemia (T -PLL), 10 cases of leukemia T of large granular lymphocytes (LGL -T) 9 cases of leukemia cells of adult T (LCTA), 5 cases of Sezary syndrome (SS) and a case of large granular NK leukemia (LGL -NK) lymphocytes. In conclusion, the combined use of the monoclonal antibody panel careful cytomorphological analysis was shown to be essential in immune diagnosis and classification of chronic lymphoproliferative disorders. This study was approved by the IRB - HUOL under number 356 / 09

Parâmetros hematológicos de jumentas gestantes em diferentes períodos

The hematological parameters and total protein concentration in healthy donkeys during pregnancy, under grass handling conditions in tropical weather, were evaluated. Fifth-two Marchador Brasileiro breed healthy donkeys, ranging from 8 to 16 years old, were evaluated, 36 of which were pregnant. The animals were separated in four groups: non pregnant (control), pregnancy from 25 to 110 days (first phase), from 111 to 210 days (second phase), and from 211 to 340 days (third phase). Total protein, erythrocyte, and leukocytes counts; packed cell volume; hemoglobin concentration; hematimetric absolute rates of mean corpuscular volume (MCV); mean corpuscular hemoglobin (MCH); and mean corpuscular hemoglobin concentration (MCHC) were evaluated. Total protein and eosinophils count decreased in the first phase. Red blood cells, hemoglobin concentration, and MCHC increased in the third phase of pregnancy. However, MCV and MCH decreased in the same phase.

Efeito do sítio de venopunção nos parâmetros hematológicos em tigre-d'água-americano, Trachemys scripta elegans

O objetivo do presente estudo foi realizar a comparação entre dois sítios de coleta sanguínea em 24 exemplares de tigre-d'água-americano (Trachemys scripta elegans) oriundos de um criadouro comercial, localizado no município de Antonina, litoral do Paraná, Brasil. Os animais foram submetidos a contenção física e as venopunções foram realizadas no seio supraocciptal e na veia coccígea dorsal. As amostras heparinizadas foram identificadas e refrigeradas para posterior análise laboratorial. A contagem total de eritrócitos e leucócitos foi realizada pela técnica de hemocitometria. O hematócrito (Ht) e a hemoglobina (Hb) foram determinados pelo método de microhematócrito e cianometahemoglobina, respectivamente. A proteína plasmática total (PPT) foi determinada por refratometria e a contagem diferencial de leucócitos foi realizada através da técnica de Shilling. Houve diferença significativa no número de leucócitos e no valor da proteína plasmática total, e em ambos os casos os valores encontrados nas amostras provenientes da veia coccígea dorsal foram inferiores. A diferença encontrada no número de leucócitos provavelmente foi devido à contaminação por linfa, que também justifica o menor valor na concentração da proteína plasmática total. Conclui-se que é mais indicada a venopunção no seio supraocciptal quando comparado a veia coccígea dorsal.

Efeitos do tratamento com formalina e sulfato de cobre sobre os parâmetros hematológicos e parasitos monogenéticos em juvenis de Hemigrammus sp. (Osteichthyes: Characidae)

The objective of this study was to evaluate the effectiveness of formalin and copper sulphate to control monogeneans in juvenile Hemigrammus sp and its effect on leukocyte count. We used a completely randomized design with five treatments and three replications. All treatments lasted for three days and consisted of: T1, control; T2 and T3 immersion bath for one hour in formalin, an of two concentrations of 0.25 ml formalin and the other 0.1 ml L-1; the T4 bath for 24 hours with 0,025 ml of formalin-L-1; and T5, bath 24 hours with copper sulphate (0.3 mg L-1). After the experimental period was observed that T2, 100% mortality. The T3 and T5 provided 100% efficiency, however, fish presented mortalities and intoxication of the 66 and 80% respectively. T4 showed an efficacy of 77.7% and decrease in parasitological indices: total number of parasites of11, 3 ± 9, mean infection intensity of 3.2 ± 2 and a prevalence of 47.1%. As the leukocytes was observed that at T3, T4 and T5 occurred differences in the proportion of lymphocytes, monocytes and neutrophils as compared to control. The CuSO4 and formalin reduce the parasite load, but presented to be toxic at higher concentrations.

Incorporação de probióticos na dieta para juvenis de tilápias-do-nilo: Parâmetros hematológicos, imunológicos e microbiológicos

Probiotics are generally considered as live microorganisms which, when administered in adequate amounts, confer a health benefit to the host. The processing method of diet and the form of inclusion of probiotic can interfere in hematological, immunological and microbiological parameters in fish. The aim was to estimate the hematological, immunological and microbiological parameters in juveniles of Nile tilapia, fed probiotic, included before and after the process of pelletization and extrusion. The experimental design was completely randomized, with five treatments: pelleted diet without probiotic, pelleted diet with inclusion of probiotic before and after processing, extruded feed without probiotic and extruded feed with inclusion of probiotic after processing and five replications. Two hundred and fifty fish were distributed in 25 aquaria (20 L) and fed for 63 days. The blood composition (red and white) showed no significant differences except mean corpuscular hemoglobin concentration of control when compared to other treatments. The phagocytic capacity of the animals that had received the extruded diet supplemented with probiotic was significantly higher when compared to the other treatments. However, there were no differences between the treatments regarding to the phagocytic index. Fish fed the extruded diet exhibited significant improvement in the nonspecific immunity. The probiotic bacteria colonized the intestine, since it was possible to recover them. We can affirm that these fishes remained healthy, because the hematological parameters were not altered during the experimental. The study shows that any form type of inclusion in the feed tested (before or after and after pelletizing extrusion) may be easily used by the fish farmer.
