14. Paradoxical effects of brain death and associated trauma on rat mesenteric microcirculation: an intravital microscopic study
OBJECTIVE: Experimental findings support clinical evidence that brain death impairs the viability of organs for transplantation, triggering hemodynamic, hormonal, and inflammatory responses. However, several of these events could be consequences of brain death-associated trauma. This study investigated microcirculatory alterations and systemic inflammatory m

15. Estudo das alterações cardiovasculares e metabólicas em modelo experimental de programação metabólica: efeito de extrato da casca de uva Vitis vinífera / Study of cardiovascular and metabolic alterations in experimental model of metabolic programming: effect of extract from skin of grape extract of grape Vitis vinifera
Epidemiological and experimental studies have suggested that cardiovascular risk factors can be partly attributed to the influences of the environment in which the individual lives, and that maternal nutrition influences the programming of metabolic and cardiovascular diseases in adults characterizing the metabolic syndrome. On the other hand, previous studi

16. Vascularization of the small intestine in lesser anteaters, Tamandua tetradactyla (Xenarthra: Myrmecophagidae)
The blood supply in the small intestine of seven Tamandua tetradactyla (Linnaeus, 1758), was studied. The method included preparation of the macroscopic collection report, perfusion of the arterial network with water (40ºC), injection of colored latex (Neoprene 650®, 2350-0003 Suvinil® dye), fixation in formaldehyde (10%), and preservation in ethanol (50%

17. Hepatite granulomatosa em bovino causada por Mycobacterium avium subsp. paratuberculosis
Samples from intestines, liver, and lymph nodes were collected from a dairy steer with clinical suspicion of paratuberculosis. The samples were processed for histologic examination with hematoxylin-eosin and Zihel-Neelsen (ZN) staining for the detection of acid-fast bacilli (AFB), and submitted to immunohistochemistry (IHC). Macroscopic changes were observed

18. Effects of different peep levels on mesenteric leukocyte-endothelial interactions in rats during mechanical ventilation
INTRODUCTION: Mechanical ventilation with positive end expiratory pressure (PEEP) improves oxygenation and treats acute pulmonary failure. However, increased intrathoracic pressure may cause regional blood flow alterations that may contribute to mesenteric ischemia and gastrointestinal failure. We investigated the effects of different PEEP levels on mesenter

19. Efeitos da ventilação mecânica e pressão positiva no final da expiração sobre a microcirculação mesentérica em ratos Wistar / Effects of mechanical ventilation and positive end-expiratory pressure on mesenteric microcirculation in Wistar rats
Ventilação mecânica (MV) com pressão positiva no final da expiração (PEEP) melhora a oxigenação sanguínea e oferta de oxigênio aos tecidos no tratamento da insuficiência respiratória aguda. No entanto, a pressão intratorácica elevada pode alterar o fluxo sanguíneo no mesentério que pode contribuir para complicações gastrointestinais durante

20. Association of oxamniquine praziquantel and clonazepam in experimental Schistosomiasis mansoni
The antischistosomal activity of clonazepam, when administered alone or in association with oxamniquine and praziquantel, was experimentally evaluated in mice infected with Schistosoma mansoni. The animals were treated 45 days post-infection with a single dose, by oral route, according to three treatment schedules: clonazepam 25 mg/kg and sacrificed 15 min,

21. Morphoquantitative aspects of undernourishment-induced neuroplasticity in the rat´s celiac ganglion neurons. / Aspectos morfoquantitativos da neuroplasticidade induzida por desnutrição no gânglio celíaco de ratos
The celiac ganglion belongs to the celiac plexus which consists of a net of nerves and supportive tissues. The celiac ganglia, even, are alonged and locate along the caudal face of the origin of the celiac artery. On the left side the ganglion is linked by an interganglionar branch. It is intimately in contact with the surface of the aorta. The autonomous in

22. Angiostrongylus costaricensis: complete redescription of the migratory pathways based on experimental Sigmodon hispidus infection
Angiostrongylus costaricensis lives in the cecal and mesenteric arteries of its vertebrate hosts, and causes an inflammatory disease in humans. To investigate unknown aspects of the abdominal angiostrogyliasis pathogenesis, infected Sigmodon hispidus were sequentially studied in different times of infection. The study revealed that L3 goes alternatively thro

23. Estudo comparativo da celularidade da reação inflamatória aguda na serosa e mesentério intestinais às telas de poliamida e polipropileno em ratos wistar com peritonite fecal por técnica morfométrica
Laparostomy constitutes in important strategy in the management of patients with severe acute peritonitis and compartmental abdominal syndrome. Prosthetic materials are used to close the abdominal cavity temporally and the polyamide has been little mention in medical literature. Researches are about chronic inflammatory response. However in laparostomy the p

24. Differential expression of integrin subunits on adherent and nonadherent mast cells
Mast cell progenitors arise in bone marrow and then migrate to peripheral tissues where they mature. It is presumed that integrin receptors are involved in their migration and homing. In the present study, the expression of various integrin subunits was investigated in three systems of adherent and nonadherent mast cells. Mesentery mast cells, freshly isolat
