Effects of oral administration of 5 immunosuppressive agents on activated T-cell cytokine expression in healthy dogs.

Background: Dogs are often adminstered >1 immunosuppressive medication when treating immune-mediated diseases, and determining whether these different medications affect IL-2 expression would be useful when performing pharmacodynamic monitoring during cyclosporine therapy.

Hypothesis/objectives: To determine the effects of 5 medications (prednisone, cyclosporine, azathioprine, mycophenolate mofetil, and leflunomide) on activated T-cell expression of the cytokines IL-2 and interferon-gamma (IFN-γ).

Animals: Eight healthy dogs.

RESULTS OF THE MEGAVEREBRATE ANALGESIA SURVEY: GIRAFFE AND HIPPOPOTAMUS.

Results of an online survey posted on the American Association of Zoo Veterinarians listserv examined the patterns of analgesic medication and pain management modalities used for captive giraffe and hippopotami. Compiled data included signalment, drugs administered, dosing regimens, subjective efficacy scores, ease of administration, and adverse events. Nineteen institutions exhibiting hippopotami ( Hippopotamus amphibious ) and pygmy hippopotami (Choeropsis liberiensis) and 45 exhibiting giraffe ( Giraffa camelopardalis spp.

RESULTS OF THE MEGAVERTEBRATE ANALGESIA SURVEY: ELEPHANTS AND RHINO.

An online survey utilizing Survey Monkey linked through the American Association of Zoo Veterinarians listserve examined current practices in megavertebrate analgesia. Data collected included drugs administered, dosing regimens, ease of administration, efficacy, and adverse events. Fifty-nine facilities (38 housing elephants, 33 housing rhinoceroses) responded.
