Hematologic, serum biochemistry and urinary values for captive Crab-eating Fox (Cerdocyon thous) in São Paulo state, Brazil

A importância do estudo dos valores hematológicos, de bioquímica sérica e urinários de Cachorro-do-mato (Cerdocyon thous) baseia-se na necessidade de cuidados e manutenção da sanidade destas populações. Este estudo visou investigar os parâmetros fisiológicos hematológicos, de bioquímica sérica e urinários dos Cachorros-do-mato de cativeiro, comparando as possíveis diferenças sexuais e de faixa etária. Foram colhidas amostras de sangue de 52 animais, pertencentes a diversos Zoológicos do Estado de São Paulo, Brasil. Foram colhidos cerca de 7mL de sangue, que foram utilizados para se obter os valores hematológicos e o perfil de bioquímica sérica. Também foram colhidos 5mL de urina para realização da urinálise. Não se encontraram diferenças entre os valores obtidos para machos e fêmeas tanto na hematologia, quanto na bioquímica sérica. Alguns parâmetros hematológicos e de bioquímica sérica foram afetados pela idade, mostrando diferenças significativas. Os resultados da urinálise foram demonstrados apenas em forma descritiva. Os principais valores encontrados foram, hemácias 4,35+0,73 x 106 células /µL, leucócitos totais 7,72+3,66 x 103 células /µL (predomínio de neutrófilos segmentados), plaquetas 227,06+111,58 x 103 células /µL, ureia 43,06+14,28mg/dL e creatinina 1,03+0,24mg/dL. Os valores hematológicos, de bioquímica sérica e urinários obtidos neste estudo podem ser utilizados como valores fisiológicos de Cachorros-do-mato de cativeiro. Pode-se concluir que as espécies silvestres necessitam de seus próprios valores de referência com necessidade de se diferenciar animais em cativeiro de animais de vida livre.

Hematological changes in sheep inoculated with natural and Cobalt60-irradiated Crotalus durissus terrificus venom (Laurenti, 1768)

Natural (NV) and Cobalto60-irradiated (IrV) Crotalus durissus terrificus venom were used to evaluate serum production capacity of sheep and possible hematological and biochemical effects. Freeze-dried venom aliquots were diluted in acidified saline solution (NaCl 150 mM, pH 3.0) and irradiated by a Cobalt 60 source at a dose of 5.54 x 102 Gy/h and a concentration of 2.000 Gy. Twelve sheep were divided into two groups of six animals. One group received irradiated venom (IrV) and the other natural venom (NV). Three antigen doses (venom) were administered at monthly intervals. Blood samples were collected weekly for analysis of serum neutralization potency and capacity, complete blood count (CBC), total plasma protein, fibrinogen, albumin, and globulin. At the end of the experiment, the animals were challenged with a LD50 for sheep and showed no signs of envenoming. The two groups did not present clinical alterations. Results of the total leukocyte count did not present interaction or time factor effect for both groups, but there was a different action between them, with the NV group presenting more cells than the IrV group. The leukocyte increase to 13,000/ml indicates that slight leukocytosis occurred in the week after the first inoculation in the NV group. There was no statistically significant difference between groups in the absolute count of segmented neutrophils, eosinophils, and lymphocytes but there were statistically significant oscillations in values at the different collecting times. The NV group presented an increase in the absolute neutrophil count after the first inoculation that persisted for 5 weeks. In the IrV group, the increase in neutrophils occurred only in the first week returning to normal in the following weeks. The alterations in the neutrophil count are indicative of systemic inflammatory response related to cytokine release; response was more marked in the NV group, showing its greater toxicity.

In vitro antifungal susceptibility of Candida spp. oral isolates from HIV-positive patients and control individuals

Oropharyngeal candidiasis is the most common fungal infection among HIV-positive patients. This condition can be treated with either systemic or topical antifungal agents; treatments are usually indicated empirically on the basis of clinical data. The knowledge of in vitro antifungal susceptibility is important to determine correct therapeutic guides for the treatment of fungal infections. Therefore, the objective of this study was to determine the antifungal susceptibility profile of oral Candida isolates from HIV-positive patients and control individuals. Amphotericin B, fluconazole, flucytosine, nystatin and ketoconazole were tested according to the methodology of microdilution proposed by the Clinical and Laboratory Standards Institute (CLSI); results were recorded in values of minimal inhibitory concentration (MIC). A total of 71 Candida isolates from HIV-positive patients were examined with the following species represented: C. albicans (59), C. tropicalis (9), C. glabrata (1), C. guilliermondii (1) and C. krusei (1). A total of 15 Candida isolates were evaluated from control individuals comprised of 11 C. albicans and 4 C. tropicalis samples. Our results demonstrated that the tested antifungal agents showed good activity for most isolates from both groups; however, variability in MIC values among isolates was observed.

GENETIC-RELATIONSHIP, INBREEDING AND GENERATION INTERVAL IN REGISTERED GIR CATTLE IN BRAZIL

Two-hundred random pedigrees of cows and fifty of sires born in 1987 from the Gir herdbook of the Brazilian Association of Zebu Breeders were analized. The bull Chave de Ouro DGR no. 2851 was the most influential animal with a 7 % direct relationship to the breed. Total average inbreeding was 3.62 and 3.25 for the female and male sample, respectively. The subdivision of total inbreeding into current and non-current components resulted in values of 1.62, 1.25, 2.00 and 2.00 for the female and male sample, respectively. Long-term inbreeding was the principal component of non-current inbreeding, with values of 1.52 % and 1.26 %, respectively. Inbreeding due to strain formation strain due formation was less important (0.48 % and 0.74 %, respectively). The average generation interval was 8.02 years. The breed appears not yet to be subdivided into strains but this process may be starting. The average generation interval for the pedigree population was very high. Culling of old bulls could decrease this interval.

Association between polyclonal B cell activation and the presence of autoantibodies in mice infected with Yersinia enterocolitica O:3

Eight-week old conventional female Swiss mice were inoculated intravenously with Yersinia enterocolitica O:3. A second group of normal mice was used as control. Five mice from each group were bled by heart puncture and their spleens were removed for spleen cell collection on the 3rd, 5th, 7th, 10th, 14th and 21st day after infection. Immunoglobulin-secreting spleen cells were detected by the isotype-specific protein A plaque assay. Total immunoglobulin levels were determined in mouse serum by single radial immunodiffusion and the presence of autoantibodies was determined by ELISA. We observed a marked increase in the total number of cells secreting immunoglobulins of all isotypes as early as on the 3rd day post-infection and the peak of secretion occurred on the 7th day. At the peak of the immunoglobulin response, the total number of secreting cells was 19 times higher than that of control mice and most immunoglobulin-secreting cells were of the IgG2a isotype. On the 10th day post-infection, total serum immunoglobul in values were 2 times higher in infected animals when compared to the control group, and continued at this level up to the 21st day post-infection. Serum absorption with viable Y. enterocolitica cells had little effect on antibody levels detected by single radial immunodiffusion. Analysis of serum autoantibody levels revealed that Y. enterocolitica infection induced an increase of anti-myosin and anti-myelin immunoglobulins. The sera did not react with collagen. The present study demonstrates that Y. enterocolitica O:3 infection induces polyclonal activation of murine B cells which is correlated with the activation of some autoreactive lymphocyte clones.

Modalities for soil preparation and gypsum application in ultisol: stem productivity of sugarcane

O trabalho foi conduzido em área de expansão de cana-de-açúcar da Usina Vale do Paraná, no município de Suzanápolis - SP, na região do noroeste paulista. Foi utilizada a variedade de cana RB92-5345, espaçamento de 1,5 m entre linhas, em ARGISSOLO VERMELHO. O trabalho objetivou avaliar a produtividade em cana-planta e 1ª cana-soca e alguns atributos químicos de solo, em função dos métodos de preparo do solo e aplicação ou não de gesso. O delineamento experimental utilizado foi o de blocos ao acaso, com seis tratamentos, fatorial 3x2, e seis repetições. Os tratamentos principais foram preparos de solo com três equipamentos: arado de aivecas, escarificador e grade pesada, e dois tratamentos secundários com aplicação de 1 t ha-1 de gesso e sem gesso. Após cada colheita da cana, o solo foi caracterizado quanto aos indicadores de fertilidade nas camadas de 0,0-0,15; 0,15-0,30 e 0,30-0,45 m. As diferenças dos atributos químicos do solo, devido aos métodos de preparo ocorridas na cana-planta, não perduraram até a colheita da 1ª cana-soca e também não influenciaram na produtividade da cultura. A gessagem proporcionou maiores valores de ATR e produtividade de TCH, para cana-planta e 1ª cana-soca, respectivamente, confirmando a hipótese inicial.

Evaluation of longitudinal modulus of elasticity in wood species for structural application

1024x768 This research aimed to investigate possible differences in values of longitudinal modulus of elasticity for wood species usually employed for structural purposes, as Castanheira (Bertholletia excelsa), Cambará (Erisma uncinatum), Cumaru (Dipteryx odorata), Jatobá (Hymenaea stilbocarpa), Garapa (Apuleia leiocarpa) and Peroba Rosa (Aspidosperma polyneuron), obtained from compression and tension parallel to grain, and static bending tests. Recommendations of the Brazilian standard ABNT NBR 7190:1997, Annex B, were followed. Statistical analysis results for the cited properties, had equivalent averages for the six wood species analyzed. This confirms that any of the three tests can be used to obtain the longitudinal elastic modulus and which could avoid the necessity of evaluating stiffness values for wood by more than one kind of mechanical test.
