          Abstract

          Avaliou-se a resposta de fase aguda através da determinação da concentração das proteínas de fase aguda (PFAs) no soro sanguíneo e no líquido peritoneal de dez equinos submetidos à orquiectomia. Foram colhidas amostras de sangue e líquido peritoneal antes do procedimento de orquiectomia (T0) e diariamente, até o sexto dia (T1-T6) pós-operatório. As PFAs foram separadas por eletroforese em gel de poliacrilamida contendo SDS-PAGE, e suas concentrações determinadas por densitometria computadorizada. Foram identificadas no soro e no líquido peritoneal, no pré e pós-operatório, as proteínas ceruloplasmina, transferrina, albumina, haptoglobina e α1-glicoproteína ácida. No pós-operatório, verificaram-se alterações nas concentrações séricas e peritoneais das PFAs, as quais foram associadas à resposta inflamatória desencadeada pelo trauma cirúrgico. A orquiectomia desencadeia reação inflamatória em equinos e o proteinograma pode ser utilizado para diagnosticar e monitorar complicações pós-operatórias

          Translated abstract

          The acute phase response was evaluated by determining the concentration of acute phase proteins (APP) in blood serum and peritoneal fluid in ten equines submitted to orchiectomy blood and peritoneal fluid samples were collected before the orchiectomy procedure (T0) and daily until the sixth postoperative day (T1-T6). The APPs were separated by electrophoresis on polyacrylamide gel containing SDS - PAGE and their concentrations were determined by computerized densitometry. There were identified in serum and peritoneal fluid, during pre and postoperative period, the acute phase proteins: ceruloplasmin, transferrin, albumin, haptoglobin and α1-acid glycoprotein. Postoperatively, there were changes in serum and peritoneal APPs, which were associated with the inflammatory response induced by surgical trauma. The orchiectomy triggers inflammatory reaction in equines and the proteinogram can be used to diagnose and monitor the postoperative complications

          Current research on acute phase proteins in veterinary diagnosis: an overview.

          The acute phase proteins (APP) are a group of blood proteins that contribute to restoring homeostasis and limiting microbial growth in an antibody-independent manner in animals subjected to infection, inflammation, surgical trauma or stress. In the last two decades, many advances have been made in monitoring APP in both farm and companion animals for clinical and experimental purposes. Also, the mechanism of the APP response is receiving attention in veterinary science in connection with the innate immune systems of animals. This review describes the results of recent research on animal APP, with special reference to their induction and regulatory mechanisms, their biological functions, and their current and future applications to veterinary diagnosis and animal production.

            Current concepts of the inflammatory response after major trauma: an update.

            During the past century explosive developments have taken place in the field of molecular medicine and genetics, vastly expanding our understanding of the normal physiological response to injury. We have been able to characterise specific molecular and cell biological processes and apply some of this knowledge to the treatment of multiply injured patients. Despite the significant steps we have made, there still remains much work to be done in this area. This review article highlights the current concepts of post-traumatic immunological changes and their impact in the management of trauma patients.

              Acute phase response to surgery of varying intensity in horses: a preliminary study.

              To evaluate the postoperative inflammatory response of horses to elective surgery of varying intensity. Prospective longitudinal study. Horses referred to 2 hospitals for either arthroscopic removal of a unilateral osteochondritic lesion in the tibiotarsal joint (minimal surgical trauma, n=11), correction of recurrent laryngeal neuropathy by laryngoplasty and ventriculectomy (intermediate surgical trauma, n=10) or removal of an ovarian tumor by laparotomy (major surgical trauma, n=5). Horses had a thorough clinical examination every day. White blood cell (WBC) counts and concentrations of serum amyloid A (SAA), fibrinogen, and iron were assessed in blood samples obtained before, and 1-3, 5, 7, 9, and 11 days after surgery. Differences in levels of the inflammatory markers between the 3 surgical groups were analyzed using repeated measures ANOVA. Postoperative concentrations of SAA and fibrinogen were significantly higher in horses that had laparotomy and ovariectomy than in horses that had laryngoplasty and ventriculectomy, or arthroscopy. Iron concentrations decreased to lower levels after intermediate and major surgical trauma than after small surgical trauma. WBC count did not differ between the 3 groups. Levels of SAA, fibrinogen, and iron reflected the intensity of the surgical trauma, whereas WBC count did not. Postoperative measurements of SAA, fibrinogen, and iron may be useful for comparing surgical trauma associated with new and established surgical techniques. Moreover, knowledge of the normal postoperative acute phase response is essential, if acute phase reactants are to be used for monitoring occurrence of postoperative infections.
