| Data from the Brazilian Mangalarga Marchador Breed Association, including information on 292,012 animals borned from 1949 to 2000 were used to describe population structure. Frequency tables, central tendency and variation measurements according to owner, breeder, type of registration (known and unknown pedigree), year and month of births, progeny number for stallions and mares were presented. A total of 72.6% of the animals originated from the Southeast States of Brazil. The maximum number of birth (6.7%) was observed in 1990 and approximately 90.0% of the births occurred from September to March. Concerning progeny numbers, 73.6% of the 90,018 mares produced an average of 3.8 and a maximum of 22 offsprings. For the stallions these numbers were 26.2 and... |

| Toxoplasma gondii and Trypanosoma cruzi are intracellular parasites which, as part of their life cycle, induce a potent cell-mediated immunity (CMI) maintained by Th1 lymphocytes and IFN-<FONT FACE="Symbol">g</font>. In both cases, induction of a strong CMI is thought to protect the host against rapid parasite multiplication and consequent pathology and lethality during the acute phase of infection. However, the parasitic infection is not eliminated by the immune system and the vertebrate host serves as a parasite reservoir. In contrast, Leishmania sp, which is a slow growing parasite, appears to evade induction of CMI during early stages of infection as a strategy for surviving in a hostile environment (i.e., inside the macrophages which are... |

| Host resistance to Trypanosoma cruzi infection is dependent on both natural and acquired immune responses. During the early acute phase of infection in mice, natural killer (NK) cell-derived IFN-<FONT FACE="Symbol">g</font> is involved in controlling intracellular parasite replication, mainly through the induction of nitric oxide biosynthesis by activated macrophages. We have shown that IL-12, a powerful inducer of IFN-<FONT FACE="Symbol">g</font> production by NK cells, is synthesized soon after trypomastigote-macrophage interaction. The role of IL-12 in the control of T. cruzi infection in vivo was determined by treating infected mice with anti-IL-12 monoclonal antibody (mAb) and analyzing both parasitemia and mortality during the... |

| O presente estudo foi conduzido para avaliar a influência da inclusão do resíduo do processamento de abacaxi (Ananas comosus L.) nas dietas sobre os consumos (por unidade de tamanho metabólico - UTM) e coeficientes de digestibilidade da matéria seca (MS), matéria orgânica (MO), proteína bruta (PB), extrato etéreo (EE), fibra detergente neutro (FDN), fibra detergente ácido (FDA), hemiceluloses (HCEL), celulose (CEL) e energia de dietas experimentais isofibrosas e isoprotéicas. Avaliaram-se também os balanços nitrogenados e de energia dos animais. Vinte ovinos machos, inteiros receberam rações com quatro níveis de inclusão do resíduo (0; 11%; 16%; 27%) em base de matéria seca, em delineamento inteiramente ao acaso, com cinco repetições por tratamento.... |
