“…Both enzymes are liver-specific, although ALAT activity in pigs is low (Boyd, 1983), and the bone is the primary source of ALP in growing animals (Kramer and Hoffmann, 1997). There might be a weak correlation with hepatitis prevalence, as category averages of enzyme activities seem to follow a similar pattern.…”

“…Comparison with reference values is complicated by a number of factors, including that the values may be out of date and therefore no longer applicable for modern breeds (Lumsden, 1998). In the present animals, sedation (Evans, 1994) and freezing of the serum (Kramer and Hoffmann, 1997) are further possible sources of systematic errors.…”

“…The distribution of continuous and categorical variables was investigated using Kolmogorov-Smirnov and Shapiro-Wilk tests, as well as Q-Q plots. One individual was excluded from the clinicochemical analyses because of haemolysis (category C tb , Kramer and Hoffmann, 1997), and one outlier from CK data (category C no , CK 5 9367).…”

Health in relation to tail-biting behaviour was investigated on a problem farm. Quartets (n 5 16) of age-and gender-matched fattening pigs including a tail biter (TB, n 5 16), a victim (V, n 5 16), a control in the same pen (C tb , n 5 10) and a control in a pen where no tail biting was observed (C no , n 5 14) were chosen by direct behavioural observation. Haematological and clinicochemical analyses, autopsy and histological examination of 16 different tissues were carried out. Tail lesion severity was evaluated both macroscopically, on the basis of inspection, and histologically, in the sagittally cut tail. Category effects were tested using Friedman's ANOVA by Ranks, Cochran's Q or a repeated-measure GLM and, if significant, pair-wise tests were conducted using Wilcoxon Signed Ranks or McNemar's Test. The number of received tail bites correlated better with histological than with macroscopic tail lesion scoring because of deep inflammation beneath healthy skin in some cases. Most individuals had mild inflammatory lesions in internal organs suggestive of generalized activation of the immune system, and 30% of the animals were anaemic, possibly because of systemic spread of infectious agents. V had more severe respiratory organ lesions and higher serum protein concentrations than all other categories of pigs. Liver-and muscle-specific enzymes (alanine aminotransferase, alkaline phosphatase and creatine kinase) differed between categories. In conclusion, most animals had signs of generalized activation of the immune system, possibly because of systemic spread of infectious agents. V pigs suffered from more severe inflammatory lesions than TB, C tb or C no . Deep infections may exist under healthy skin in the tail of bitten pigs.

“…Como o colostro de vaca, ovelha e cabra contém grande atividade de GGT (Kramer 1989), espera-se que seus valores no soro sejam inϐluenciados pela ingestão de macromoléculas presentes no colostro, ocorrendo a sua passagem através do trato digestório e, posteriormente, à corrente sanguínea do recém-nascido (Fagliari et al 1996). A análise dos resultados permitiu constatar aumento signiϐicativo da atividade da GGT, em todos os grupos, entre zero e dois dias de idade (Quadro 4), em virtude da maior taxa de absorção desta enzima durante o período de maior permeabilidade do epitélio intestinal.…”

Pesq. Vet. Bras. 32(8):794-802, agosto 2012 794 RESUMO.-Após o nascimento, os cabritos são dependentes das imunoglobulinas colostrais devido às características placentárias que não permitem a passagem de macromolé-culas da circulação materna. De acordo com a literatura, os cabritos possuem capacidade absortiva por até quatro dias. Muitos aspectos ϐisiológicos de outras espécies são aceitos e utilizados para caprinos, mas aqueles relacionados à transferência de imunidade passiva precisam de investigação. Os objetivos do presente estudo foram determinar o período de passagem de macromoléculas da mucosa intestinal para a circulação e a duração da proteção humoral transferida Período de absorção intestinal de macromoléculas em cabritos recém-nascidos após a ingestão de colostro bovino 1

“…Barr (1991) refiere estudios experimentales en perros infectados con T. cruzi, donde una significativa elevación de la AST se asoció con desfavorables resultados durante el estado agudo de la infección, presentándose en todos los casos miocarditis aguda fatal. Kramer (1989) y Dial (1995, con relación a esta enzima (AST), advierten que su situación sérica es un buen marcador de cualquier daño en los tejidos blandos, imposibilitándose, de esa manera, su uso como una enzima órgano-específica.…”

La presente comunicación reporta los valores de las enzimas transaminasas, Aspartatoaminotransferasa (AST) y Alaninaaminotransferasa (ALT) encontrados en sueros de cabras infectadas con la cepa de Trypanosoma vivax Stock (TvIIV) y sus controles. Las determinaciones se realizaron durante un lapso experimental de diez semanas, divididos en dos períodos iguales (pre y post-infección) por intermedio de un método colorimétrico, utilizando kits comerciales. Los datos fueron analizados mediante la prueba t Student's. En el caso de la AST, la comparación de las medias parciales de ambos grupos infectado y control, no indicó diferencias estadísticas. Con respecto a la ALT, la contrastación de las medias parciales de pre y post-infección del grupo de cabras infectadas, señaló diferencias significativas (P<0,01).
