Background: Current advances in immunotherapy are an exciting area of study in canine osteosarcoma (OSA). The objective of this study was to determine the immune response in dogs with osteosarcoma by measuring stimulated leukocyte production of tumor necrosis factor (TNF), interleukin (IL)-6, IL-10 and TNF and IL-6 to IL-10 ratios.

Methods: Whole blood was collected from dogs with osteosarcoma receiving non-steroidal anti-inflammatory drugs (NSAIDs, n = 11), dogs with osteosarcoma not receiving NSAIDs (n = 14) and healthy dogs (n = 5).

Resveratrol is a polyphenol that is safe to administer to dogs and has immunomodulating properties. Canine in vitro work indicated that resveratrol spared polymorphonuclear cell (PMN) phagocytosis but reduced the robustness of PMN oxidative burst and resulted in a pro-inflammatory leukocyte cytokine profile. The objective of this study was to determine the short-term effect of resveratrol on the healthy canine innate immune system in vivo.

Purpose: The aim of this study was to assess the potential detrimental effects of the operating room environment on exposed healthy articular cartilage and to evaluate tissue hydration treatment strategies for preserving chondrocyte viability and extracellular matrix composition in this environment.

Methods: With institutional Animal Care and Use Committee approval, femoral and tibial condyles (n = 36; 6 per specimen) were harvested from canine cadavers (n = 6) immediately after euthanasia and placed on a draped operating table under standard surgical lighting for a timed 2-hour period. Each condyle was randomly assigned to one of 6 groups (n = 6 per group): no-treatment control, hyaluronic acid (HA), saline sponge, saline drip, culture media (Dulbecco's modified Eagle's medium [DMEM]) sponge, or culture media drip.
