ABSTRACT

Purpose: To evaluate the effects of the intra-articular application of hyaluronic acid associated with triamcinolone acetonide, and ozone gas in the treatment of induced osteoarthritis in rabbit’s stifles.Methods: Twenty-one Norfolk rabbits were submitted to cranial cruciate ligament transection of the left stifle. After six weeks of the surgery, the rabbits were randomized assigned into three groups: G1 (control) – saline solution (0.9%); G2 – hyaluronic acid associated with triamcinolone; G3 – ozone gas, submitted to three intra-articular applications every seven days. Results: Significant differences occurred: osteophytes at medial femoral condyle (G2 > G1, G2 > G3) on radiography exam; thickening of the medial condyle (G1 > G3, G2 > G3) on ultrasound exam; osteophytes at lateral tibial condyle (G2 > G1, G2 > G3), and medial femoral condyle (G1 > G2, G3 > G1) on computed tomography. Histologically, mean values of chondrocytes in the femur and tibia in G3 and G2 were statistically lower. Conclusions: The intra-articular injection of hyaluronic acid associated with triamcinolone accentuated degenerative joint disease by imaging and macroscopic evaluations, and by histological findings, this treatment and the ozone gas treatment showed similar effects and were inferior to the saline solution (0.9%).

ABSTRACT

O presente relato teve como objetivo descrever um caso de leucemia linfocítica B em um cão da raça maltês, fêmea, com três anos de idade, demonstrando a metodologia de diagnóstico e a variação da patologia clínica após o tratamento exclusivamente por esplenectomia. A linfocitose acentuada observada no hemograma e presença proliferativa de linfócitos na medula óssea determinou a suspeita da leucemia linfocítica. A leucemia linfocítica B foi diagnosticada por meio da citologia aspirativa da medula óssea, imunocitoquímica e citometria de fluxo. O tratamento foi exclusivamente por esplenectomia e dois anos após a cirurgia o animal não apresentou recidiva da afecção.


This report aimed to describe a case of B lymphocytic leukemia in maltese female dog, three years old, demonstrating the methodology of diagnostic and variation of clinical pathology after treatment exclusively by splenectomy. The accentuate lymphocytes observed in blood counts and presence of proliferative lymphocytes in the bone marrow were determined to diagnostic of lymphocytic leukemia. The B lymphocytic leukemia was diagnosed by bone marrow aspiration cytology, immunocytochemistry and flow cytometry. The treatment was exclusively by splenectomy and two years after the surgery the animal showed no recurrence of the disease.
