The aim of the study was to provide useful prognostic factors for dogs with CBL. Data regarding sex, breed, age, signalment, treatment and clinical course of the disease from 52 dogs diagnosed with centroblastic lymphoma (CBL) with cytology and immunocytochemistry were provisionally collected and related to the treatment outcome and survival. More than 80% of dogs were treated with chemotherapy and achieved complete remission in 80% of cases. Among the prognostic factors positively related to the overall survival time of dogs with CBL were the application of chemotherapy, achieving a complete remission, application of at least one additional chemotherapeutic agent to the basic protocol, especially the administration of mitoxantrone and asparaginase. Moreover, mitotic count 14 or higher measured in cytological slides in the area of 2,37 mm2 have been linked to shorter overall survival in dogs with CBL.Nickel damages the male reproductive system. We investigated the beneficial effects of silibinin which has metal-chelating and antioxidant properties over nickel toxicity. Both antioxidative effects in testes and overall effects related to sperm motility, membrane and acrosome integrity of orally administered Silibinin were evaluated against the harmful effects of 30 day of intraperitoneal nickel sulfate (5 mg/kg/day) administration in rats. Male rats were randomized into control (Group1; n=6) and three experimental groups (n=6, each) Group2 Nickel sulfate (5 mg/kg/day), Group3 Silibinin (150 mg/kg/day), and Group 4 Nickel sulfate (5 mg/kg/day) + Silibinin (150 mg/kg/day). We found higher sperm motility, viable sperm and total sperm count in Groups 3 and 4 than the Group 2 treatment groups and the percentage of abnormal spermatozoa was similar in both groups (Groups 2 and 4). Increased apoptosis, acti
