Pituitary corticotroph macrotumors occur in 10% to 50% of dogs with PDH. Clinical signs may be only those of hypercortisolism or may include neurologic signs such as stupor, inappetance, circling, or pacing. Currently, CT and MRI are the only tests that can confirm the presence of a pituitary macrot...

In a comparison of 2 formalin killed vaccines, SHAWOGEN using an isolate (AVC U-13220) of Vibrio anguillarum (serotype 2) isolated from cod, and a commercial vaccine (VIBROGEN-2) prepared from 3 isolates (2 V. anguillarum, and V. ordalii) the vaccines were given i.p. with mild anaesthesia, by sprayi...

A retrospective cross-sectional survey of dog-owning veterinary clients was undertaken in 1996 in three Canadian provinces (New Brunswick, Nova Scotia, and Prince Edward Island) to generate a population of dogs for future use in a more detailed survey on canine behaviour. The questionnaire was desig...

OBJECTIVE: To quantify and compare intracellular magnesium concentrations (Mgi) in clinically normal dogs (control dogs) and dogs that have gastric dilatation-volvulus (GDV dogs) and to determine whether there is a difference in Mgi and serum magnesium concentrations (Mgs) between GDV dogs with and ...

Unilateral medial patellar luxation was diagnosed in 10, and bilateral medial patellar luxation in six, large and giant-breed dogs (22 stifles). Lameness occurred in five dogs after trauma or surgery, and 11 dogs had no known predisposing history. The mean age at presentation was 25 months, and the ...

There are only a few reports in the veterinary literature describing the use of stapling equipment and techniques for pulmonary surgery. These reports indicate that complications associated with these procedures are minimal. Although pulmonary lobectomy procedures originally described independent is...

A dog adopted as a stray in Spain and then brought to Canada 4 years prior to presentation was evaluated for polyarthritis. An electrophoresis showed a marked polyclonal gammopathy and synovial smears contained leishmanial organisms within macrophages.

OBJECTIVE: To evaluate the effects of nephrotomy on renal function in clinically normal cats. ANIMALS: 20 specific-pathogen-free, 9- to 11-month-old female mixed-breed cats. PROCEDURE: Serum chemistry analyses, CBC determinations, urinalyses, microbiologic urine cultures, renal ultrasonography, abdo...

The purpose of this study was to determine the effects of conventional and intraoperative tissue expansion on the biomechanical properties of skin. Two 200-cc silicone tissue expanders were inserted subcutaneously in each of six young pigs. One expander was inflated conventionally (4 weeks) and the ...

This study was undertaken to determine whether Haemobartonella felis (Mycoplasma haemofelis), the causative bacterial agent of feline infectious anemia, infects nondomestic cats. Routine complete blood count and polymerase chain reaction (PCR) were performed to detect the gene for 16S ribosomal RNA ...

When three sets of 11, 15 and 31 varieties, respectively, were tested for grain yield in 5-23 environments, generally more than 80% of the yield variation for individual varieties was due to linear regression response. Mean yields for varieties were significantly variable in all three sets and regre...

OBJECTIVE: To determine the relationship between bispectral index (BIS) and minimum alveolar concentration (MAC) multiples of sevoflurane in cats. ANIMALS: 8 domestic cats. PROCEDURE: Each cat was anesthetized twice with sevoflurane. First, the MAC of sevoflurane for each cat was determined by use o...

Skin defects on the distal extremity (n = 7) or face (n = 1) of eight dogs were repaired using a medial saphenous fasciocutaneous or myocutaneous flap. The cause of the wounds were ablative oncological surgery (n = 4), trauma (n = 3), or radiation burn (n = 1). The flap was removed from the medial f...
