Popis: | As proteínas de fase aguda (PFA) apresentam concentrações séricas alteradas mediante processos infecciosos, inflamatórios e neoplásicos. Objetivou-se com este trabalho avaliar as variações séricas das PFA em cadelas portadoras de neoplasia mamária, comparando com a avaliação histológica e leucograma. As PFA foram avaliadas em 45 cadelas com tumor de mama, distribuídas nos grupos neoplasia benigna (n=13), maligna não ulcerada (n=24) e maligna ulcerada (n=8). O grupo controle foi composto por 20 cadelas saudáveis. Foram realizados o teste de eletroforese em gel de poliacrilamida contendo dodecil sulfato de sódio (SDS-PAGE) para identificar as PFA (albumina, ceruloplasmina, transferrina, haptoglobina Hp, α-1 antitripsina e α-1 glicoproteina ácida) e o teste ultrassensível para proteína C reativa (PCR). As pacientes com neoplasia mamária maligna ulcerada apresentaram elevações sérica para PCR e Hp e redução da albumina (PAcute phase proteins (APPs) are serum proteins whose concentrations change after infectious and inflammatory disease, and cancer. The aims of this study were to evaluate changes in APPs concentration and to correlate these findings with histological classification and WBC in female dogs with mammary tumors. APPs were studied in 45 female dogs with mammary tumor distributed in the following groups: benign (n=13), malignant without tumor ulceration (n=24), and malignant with tumor ulceration (n=8). SDS-polyacrylamide gel (SDS-PAGE) electrophoresis was used to measure APPs concentrations (albumin, ceruloplasmin, transferrin, haptoglobinHp, α-1-acid glycoprotein and α-1-antitrypsin) and ultrasensitive assay was used to evaluate serum C-reactive protein (CRP). Patients with malignant mammary neoplasia plus ulceration had significant increase of CRP and Hp, and had decreased levels of albumin (P |
