Aditivos na ensilagem do capim-elefante. I. Composição bromatológica das forragens e das respectivas silagens

The effect of the addition of ground ear corn with husks, wheat bran and saccharin, on the rate of 0, 8, 16 and 24% (dry weight of additive/wet weight of cut green grass), upon the chemical composition of both fodder and silage of Pennisetum purpureum Schum. cv. Guaçu was evaluated. A split-plot randomized block design was used. The plots were the additives and their levels and the sub-plots the material types (forage + additives and their silages). The grass was fertilized with 20 t/ha of green manure and 80, 160 and 160 kg/ha of P2O5, N and K2O, respectively. The material (chopped grass mixed with the levels of the additives) was ensiled in experimental silos (200 L plastic vessels). The dry matter percentages increased linearly as additive levels increased, being greater the effect of ground ear corn with husks. Wheat bran addition and saccharin increased the crude protein and soluble carbohydrates percentages while the ground ear corn with husks addition decreased them. Losses of dry matter soluble compounds (CP, ash and NFE) and a relative rise in the less soluble compounds (CF and organic matter) were observed.

Lesões intestinais decorrentes de isquemia e reperfusão: Fisiopatologia e modelos experimentais

The intestinal ischemia is unusual in vascular surgery emergency. Its main causes are embolisms and arterial thrombosis. In addition to severe ischemia, reperfusion of the ischemic tissues can lead to several complications that may worsen the ischemic lesion and produce a life threatening situation caused by systemic alterations. Intestinal tissue injuries due to ischemia and reperfusion have been demonstrated in clinical and experimental studies, in which pathophysiology and adequate treatment were also studied. The great variety of experimental models used and results achieved reflect the need for an intestinal ischemia and reperfusion experimental model that is simple, reproducible and consistent, in order to search for treatments that can reduce the damage caused by this situation. In this review, the main pathophysiologic aspects and the most used experimental models will be reviewed. Copyright © 2005 by Sociedade Brasileira de Angiologia e Cirurgia Vascular.

Efeitos da fenilbutazona na cicatrização de feridas cutâneas experimentais em equinos

The purpose of this study was to investigate phenylbutazone effects on second intention wound healing, and to compare the healing process between the thoracic and lumbar areas. Ten horses were submitted to circular full-thickness wound produced on both sides of the thoracic and lumbar areas. Animals were gathered into two experimental groups, one receiving daily IV injections of phenylbutazone (4,4mg/kg) and the other (control group) distillated water for five days. All wounds were daily treated with local Dakin's solution. The wound contraction rates were determined by serial measurements each 72 hours. At the 6th and 15th post surgical days, biopsies were performed for histological analysis. Thoracic and lumbar wound contraction was decreased in the phenylbutazone group. The time to complete healing was significantly greater in phenylbutazone group (49 days) than in control group (37 days). There was no significant difference between thoracic and lumbar area in the same group. Gross and histopathology analysis showed the inhibitory effect of phenylbutazone on the second-intention wound healing when compared to the control group.
