To evaluate indices of renal function in healthy, growing Beagle puppies from 9 to 27 weeks of age and to determine whether indices change with age during this period. Animals-6 healthy Beagle puppies. PROCEDURE: Urine collections were performed at 2-week intervals in puppies 9 to 27 weeks old. Dail...

OBJECTIVE: To determine the effects of medetomidine, administered i.v., on serum insulin and plasma glucose concentrations in clinically normal dogs. ANIMALS: 6 healthy adult Beagles. PROCEDURE: Dogs were randomly assigned to each of 3 treatments in a prospective cross-over study design. Serum insul...

A 1-year-old Cairn Terrier had a history of chronic coughing which was worse after eating or drinking and which had not responded to antibiotics or corticosteroids. The dog had increased bronchial tones and a mild neutrophilia and a transtracheal aspirate showed neutrophilic inflammation with sepsis...

A colorimetric method (glucose oxidase/peroxidase) for indirect measurement of glycogen concentrations in tissue homogenates of marine mussels (Mytilus edulis) was evaluated. This method uses a conversion of glycogen to glucose by amyloglucosidase. Varying the buffer pH (4.5, 5.0; 5.5) and the amylo...

A colorimetric method for indirect measurement of glycogen concentrations in tissue homogenates of eastern oysters (Crassostrea virginica) was evaluated. This method uses a conversion of glycogen to glucose by amyloglucosidase. The procedure was optimized Fur extracting buffer pH (5.0) and amylogluc...

BACKGROUND: Evaluation of serum magnesium (Mg) concentration is becoming important in human and veterinary critical care medicine. An ion-selective electrode can measure the physiologically active ionized fraction. OBJECTIVES: The purpose of this study was to validate an ion-specific electrode analy...

OBJECTIVE: To determine effects of i.v. medetomidine administration on selected clinicopathologic variables in dogs. ANIMALS: 6 healthy adult Beagles. PROCEDURE: Dogs were randomly assigned to each of 3 treatments in a crossover study design. Serum osmolality, urine osmolality, urine pH, and fractio...

A homogenous enzyme immunoassay (EIA) for measurement of serum thyroxine (T4) concentration was evaluated for use with canine and feline serum. The EIA method was linear from 0 to 150 nmol T4/L for human serum, 0 to 94 nmol T4/L for feline serum and 10 to 60 nmol T4/L for canine serum. Intra- and in...

Peritoneal fluid from 10 healthy young male Holstein calves was analyzed three times (2 to 3 days, 12 to 15 days and 27 to 30 days) during the first month of life. A new technique for collection of peritoneal fluid from calves positioned in left lateral recumbency was developed. The technique was fo...

A study was conducted to investigate whether aspiration of amniotic fluid is associated with a deleterious effect on absorption of colostral immunoglobulins or on blood gas and acid-base values of healthy newborn calves. Fourteen calves purchased from commercial sources were transported to a researc...

Methicillin-resistant Staphylococcus aureus (MRSA) colonization was not identified in any of 497 horses from Atlantic Canada. Methicillin-susceptible S. aureus (MSSA) was isolated from a subsample of 19/242 (7.9%) horses. Colonization with MSSA is relatively common in healthy horses in Atlantic Cana...

A 4-6-mo-old female red fox (Vulpes vulpes) was presented to the Atlantic Veterinary College (AVC) Teaching Hospital, Prince Edward Island, Canada. On presentation, the fox was weak and had pale mucous membranes. A complete blood count and a serum biochemistry profile were performed. Blood smear exa...
