ABSTRACT
The aim of this study was to evaluate of the efficacy of PRP employment associated with surgical sponges to improve the integration of the graft in the recipient bed. It was held at the Veterinary Hospital UNESP, Campus of Jaboticabal - SP, a study of 64 rabbits, divided into eight groups with eight animals. The groups were divided in control with saline solution 0,9%, control with PRP both without the sponge, surgical sponge with PRP, surgical sponge without PRP, and were used mesh and layer grafts in the respective groups. The data were submitted to statistical analysis (paired t-test, Kruskal-Wallis test, with subsequent use of the multiple comparison tests of Dunn, analysis of variance (F) test, Tukey test, P< 0.05). Edema and exudate with 3 and 3 and 7 days (P= 0,03 e P= 0,0049); coloring on the 14th day (P= 0,0001); cosmetic appearance on the 7th and 14th day (P= 0,0026 and P= 0,0001); mononuclear cells (P= 0,01) and polymorphonuclear (P= 0,01); fibroblast proliferation (P= 0,01); collagenous (P= 0,05); hemorrhage (P-007); necrosis and re-epithelialization (P= 0,2928 and P= 0,1). We concluded that the use of Platelet Rich Plasma Gel on skin grafts associated with a sponge as a compressive dressing promote the skin graft survival without a previous granulation tissue.(AU)
O objetivo deste estudo foi avaliar a eficácia do PRP associado com esponjas cirúrgicas na integração do enxerto ao leito receptor. Realizou-se, no Hospital Veterinário da Unesp, Jaboticabal, SP, um estudo com 64 coelhos, separados em oito grupos, com oito animais. Os grupos foram: Gprpc (PRP, sem esponja cirúrgica, enxerto camada), Gprpce (PRP, esponja cirúrgica, enxerto camada), Gcc (solução fisiológica 0,9%, sem esponja cirúrgica, enxerto camada), Gcce (solução fisiológica 0,9%, esponjas cirúrgicas, enxerto camada), Gprpm (PRP, sem esponja cirúrgica, enxerto malha), Gprpme (PRP, esponja cirúrgica, enxerto malha), Gcm (solução fisiológica 0,9%, sem esponja cirúrgica, enxerto malha) e Gcce (solução fisiológica 0,9%, esponjas cirúrgicas, malha). Os dados foram analisados pelo teste t emparelhado, Kruskal-Wallis, análise de variância, e teste de Tukey (P<0,05). Edema e exsudato presente com três e sete dias (P=0,03 e P=0,0049); coloração cianótica no 14º dia (P=0,0001); aspecto cosmético bom no sétimo e no 14º dia (P=0,00026 e P=0,0001); presença de células mononucleares (P=0,01) e polimorfonucleares (P=0,01); proliferação de fibroblastos discreta (P=0,01); colagenização intensa (P=0,05); hemorragia discreta (P=0,007); ausência de diferença significativa em necrose e reepitelização (P=0,2928 e P=0,1). Conclui-se que o emprego do PRP gel em enxertos cutâneos associando esponjas cirúrgicas como curativo compressivo favorece sua integração ao leito receptor sem a presença prévia de tecido de granulação.(AU)

The autors describe their experience with an automated immunohistochemical system applied to canine tissue samples. Twenty human cellular markers specific monoclonal and polyclonal antibodies and two different antigen retrieval methods were used in normal and neoplastic breast tissue, as well as skin samples obtained from female dogs of pure and mixed breeds. The antibodies tested were the most frequently used in human and veterinary medicine studies, employed with diagnostic purposes in breast pathology, as well as in cancer research. Most of them may be used to study other normal and abnormal tissues and included cytokeratins, progesterone receptor, c-erbB2, p53, MIB-1, PCNA, EMA, vimentin, desmin, alfa-actin, S-100, pan-cadherin, and E-cadherin. The results demonstrated that using an automated staining system it is possible to use different human markers in veterinary pathology. The advantages of automated immunohistochemistry are improved quality, reproducibility, speed, and standardisation
