An automated colorimetric method for determining lipase activity in canine sera was evaluated for precision, linearity and correlation to existing assay methods. The colorimetric method was a commercial reagent that used a series of enzymatic reactions based on the hydrolysis of 1,2 diglyceride by p...

Four hundred eighty mature marine mussels (Mytilus edulis) were collected in late April from a mussel lease in an estuary in Prince Edward Island, Canada. Squash preparations made of reproductive gland (mantle) tissue of each mussel were stained with Wright-Giemsa stain and were examined by one inve...

Hyperthyroidism can increase the renal excretion of magnesium and thus cause hypomagnesemia in various species. Anaerobically collected blood samples from 15 hyperthyroid and 40 normal, healthy cats were analyzed with an ion-selective electrode analyzer and a serum biochemical analyzer. There was no...

Five cases of hypoadrenocorticism in young related Nova Scotia duck tolling retrievers are discussed. Two were littermates and the others shared one or more common ancestors. No specific mode of inheritance was determined. Clinical and laboratory findings typical of hypoadrenocorticism were observed...

Serum C-reactive protein (CRP) concentration was measured, using an automated immunoturbidimetric assay, in 44 clinically normal dogs and 67 dogs with band neutrophil count > or = 10(9) cells/L, and values were found to be significantly (P or = 10(9) band neutrophils/L resulted in a statistically...

Cats with hyperthyroidism [(increased serum thyroxine (T(4))] commonly have increased serum alkaline phosphatase (ALP) activity in addition to other serum biochemical abnormalities. Serum biochemical profiles were obtained from 10 hyperthyroid cats which had increased serum ALP. Agarose gel electrop...

Serum sorbitol dehydrogenase (SDH) activities in 10 cows and nine horses were measured using an automated clinical analyzer. The serum samples were divided into aliquots that were stored at room temperature (21 degrees C), refrigerated (0-5 degrees C), or frozen (-30 degrees C). The stability of the...

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...
