Evaluation of a flow-mediated vasodilation measurement technique in healthy dogs.

Objective: To evaluate the between- and within-dog repeatability of a flow-mediated vasodilation (FMD) measurement technique in healthy dogs.

Animals: 43 male and female dogs of various breeds (weight range, 6.9 to 31.

Assessment of urinary N-acetyl-beta-D-glucosaminidase activity in geriatric cats with variable plasma creatinine concentrations with and without azotemia.

Objective: To validate a non-automated technique for the measurement of urinary N-acetyl-beta-D-glucosaminidase (NAG) activity in cats and assess the correlation between NAG index, plasma creatinine concentration, and proteinuria.

Animals: 197 client-owned cats (> or = 9 years old; 119 neutered males and 78 neutered females) of which 103 had previously been determined to have chronic kidney disease (CKD).

Procedures: Preliminary assay validation was performed for a non-automated colorimetric technique for quantification of NAG activity.
