A canine model of cutaneous late-phase reactions: prednisolone inhibition of cellular and cytokine responses.

Immunoglobulin E (IgE)-mediated late-phase reactions can be induced in atopic humans by intradermal injection of relevant allergens or anti-IgE antibodies. The histology of these reactions resembles that of naturally occurring atopic dermatitis. Strikingly similar responses can be induced in dogs, suggesting that a canine model could prove valuable for preclinical investigation of drugs targeting late-phase reactions.

Effect of preoperative administration of tepoxalin on hemostasis and hepatic and renal function in dogs.

Preemptive analgesia is an important part of surgical management, but some NSAIDs can adversely affect platelet function or renal or hepatic status. Tepoxalin is approved in the United States for control of pain and inflammation associated with arthritis and in Europe for relief of pain caused by musculoskeletal disorders. In this study, no significant effects on indices of hemostasis or renal or hepatic function were detected when a single preoperative oral dose of tepoxalin was administered to young healthy dogs undergoing anesthesia and surgery.
