Over a 3-yr span, two juvenile lesser flamingos (Phoeniconaias minor), two green jays (Cyanocorax yncas glaucescens), and two Montezuma oropendolas (Psarocolius montezuma) died peracutely with no premonitory signs at a zoological park in the southern United States. At necropsy, the birds were in excellent body condition. Except for one green jay, the(More)
Repeated, intermittent treatment of rats with amphetamine followed by a withdrawal period leads to an enhancement in amphetamine-induced dopamine release. We previously reported an increased stoichiometry of site 3-phospho-synapsin I and increased levels of phospho-Ser41-neuromodulin in striatum after repeated amphetamine. In this study, we examined whether(More)
Repeated, intermittent treatment of rats with amphetamine results in a sensitization of locomotor and stereotyped behaviors that is accompanied by an enhancement in stimulus-induced dopamine release. Increased phosphorylation of the neural specific calmodulin-binding protein, neuromodulin (GAP-43, B-50, F1) has been demonstrated in other forms of synaptic(More)
Repeated, intermittent treatment of rats with amphetamine results in a sensitization of locomotor and stereotyped behaviors that is accompanied by an enhancement in stimulus-induced dopamine release. The effects of repeated treatment with amphetamine on the phosphorylation state of neuromodulin and synapsin I, proteins involved in neurotransmitter release,(More)
Anesthesia in the white rhinoceros (Ceratotherium simum) has routinely involved potent narcotic anesthetic agents such as etorphine or carfentanil with their associated adverse side effects. In captive rhinoceroses conditioned to routine handling, a combination of butorphanol and azaperone at mean (+/- SD) doses of 69.3 +/- 18.0 mg and 103.1 +/- 20.9 mg,(More)
Cryopreservation of spermatozoa from free-living ocelots (Leopardus pardalis) could benefit their conservation by facilitating gene flow between in situ and ex situ populations without requiring removal of additional cats from the wild. The objective of this study was to investigate three different methods of ocelot sperm cryopreservation to identify the(More)
OBJECTIVE To assess the ability of a porcine submucosal collagen patch to enhance ventriculotomy healing in quail. STUDY DESIGN Histologic assessment of wound repair after ventriculotomy. Animal Population-Eighteen adult Japanese quail. METHODS All quail had a ventriculotomy through the caudoventral thin muscle. The quail were randomly assigned to 1 of(More)
Three immature Sunda wrinkled hornbills (Aceros corrugatus) were diagnosed postmortem with proventricular spirurid nematodiasis. Concurrent severe disseminated larval granulomatosis in other visceral organs was considered contributory to mortality in each case. Clinical signs of nematodiasis were vague but generally consisted of weight loss, anorexia, and(More)
A blue-naped mousebird (Urocolius macrourus) was diagnosed by gross necropsy and histopathology as having a chronic, fibrosing bacterial cholecystitis. Acute, severe, necrotizing pneumonia and myocarditis also were present with intralesional gram-negative bacteria. The bacteria within the lungs and heart were suspected to have spread from the biliary tract(More)
A 2-yr-old female lesser kudu (Tragelaphus imberbis australis) was presented for lethargy. Empirical antibiotic treatment appeared to improve its clinical signs, although no etiology for the symptoms was determined. The kudu again presented with lethargy, diffusely swollen limbs, and subcutaneous ecchymoses of 1 day's duration after completion of the(More)
