Distribution and Quantification of Lymphocytes in the Major Lymphoid Organs of Naturally Gumboro Infected Broilers
Provedor de dados: 77
Autores: Uddin,Mohammad Mejbah; Islam,Mohammad Saiful; Basu,Joyita; Khan,Md. Zahirul Islam.
Gumboro disease is caused by the infectious bursal disease virus (IBDV) which rapidly destroys immature B-lymphocytes of bursa of Fabricious, and causes immune suppression and high mortality in commercial broiler farms in Bangladesh. To investigate the possible effect of IBDV on lymphocytes and its distribution in the major lymphoid organs, bursa of Fabricious including spleen and thymus of naturally Gumboro-infected broilers, a research was conducted in the Department of Anatomy and Histology, collaboration with the Department of Pathology, Bangladesh Agricultural University, Bangladesh. Bursa of Fabricious, spleen and thymus of 21-days-old Gumboro-infected and non-infected broilers of same age (control) were routinely processed and stained by hematoxylin...

Effect of bee pollen on the immunity and tibia characteristics in broilers
Provedor de dados: 89
Autores: Oliveira,MC de; Silva,DM da; Loch,FC; Martins,PC; Dias,DMB; Simon,GA.
This study was carried out to evaluate the effect of bee pollen (BP) levels on the IgG and IgM titers, weight of lymphoid organs, and on the tibia morphometric measures and mineralization in broilers at 21 and 42 days of age. Four hundred birds were used in an entirely randomized design with four treatments (0, 0.5, 1 and 1.5% of BP feed inclusion) and five replicates. At 21 and 42 days of rearing, blood samples were collected for IgG and IgM analysis, as well as lymphoid organs (bursa, thymus and spleen) and the tibiae. There was no effect (p&gt;0.05) of the BP inclusion on IgG titers, bursa and spleen weights, tibia morphometric measures and mineralization at 21 and 42 days, IgM titer at 42 days or thymus weight at 21 days. However, IgM titers at 21 days...

Ontogenic development of kidney, thymus and spleen and phenotypic expression of CD3 and CD4 receptors on the lymphocytes of cobia (Rachycentroncanadum )
Provedor de dados: 42
Autores: KLOSTERHOFF,MARTA C.; PEREIRA JÚNIOR,JOABER; RODRIGUES,RICARDO V.; GUSMÃO,EMELINE P.; SAMPAIO,LUÍS A.; TESSER,MARCELO B.; ROMANO,LUIS A.
ABSTRACT In the present study was evaluated the ontogenic of immunocompetent organs of cobia up to 53 days after hatching (dah) through histology and immunohistochemistry techniques. The kidney was the first lymphohematopoietic organ to appear, at 1 dah, followed by the spleen at 5 dah and the thymus at 7 dah. The first CD3 receptors on the lymphocytes were observed in 27% of the thymic tissue at 7 dah and in 99% at 53 dah. The phenotypic expression of CD3 receptors was registered in 10% of the kidney at 8 dah and in 32% at 53 dah. CD4 receptors were observed in 5% and 63% of the thymic area at 7 and 53 dah, respectively. In the kidney, T4 lymphocytes were first observed at 13 dah in 9% of the organ and in 28% at 53 dah, defining the functional development...

Changes in the TBARs content and superoxide dismutase, catalase and glutathione peroxidase activities in the lymphoid organs and skeletal muscles of adrenodemedullated rats
Provedor de dados: 56
Autores: Pereira,B.; Costa-Rosa,L.F.B.P.; Bechara,E.J.H.; Newsholme,P.; Curi,R.
Thiobarbituric acid reactant substances (TBARs) content, and the activities of glucose-6-phosphate dehydrogenase (G6PDh), citrate synthase (CS), Cu/Zn- and Mn-superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPX) were measured in the lymphoid organs (thymus, spleen, and mesenteric lymph nodes (MLN)) and skeletal muscles (gastrocnemius and soleus) of adrenodemedullated (ADM) rats. The results were compared with those obtained for sham-operated rats. TBARs content was reduced by adrenodemedullation in the lymphoid organs (MLN (28%), thymus (40%) and spleen (42%)) and gastrocnemius muscle (67%). G6PDh activity was enhanced in the MLN (69%) and reduced in the spleen (28%) and soleus muscle (75%). CS activity was reduced in all tissues (MLN...
