Characterization of normal canine anterior cruciate ligament-associated synoviocytes.

This study was designed to identify and quantify synoviocyte phenotypes enveloping the canine anterior cruciate ligament (ACL) to test the hypothesis that there are at least two synoviocyte phenotypes, each with distinct quantities and topographical distributions. CD18 and HSP25 epitopes were colocalized in the synovium of 10 normal canine ACLs. Sagittal sections were prepared from medial, central, and lateral aspects of each ACL and phenotypes were quantified in the proximal, middle, and distal aspects of each section.

Evaluation of hemorrhage, sample size, and collateral damage for five hepatic biopsy methods in dogs.

Objectives: To compare the volume of hemorrhage, number of lobules, and portal triads available for histologic evaluation, and resultant collateral damage between 5 hepatic biopsy methods: biopsy punch, biopsy needle, ligature method, laparoscopic biopsy forceps, and ultrasonically activated scalpel (UAS).

Study Design: Experimental, repeated measures, block.

Animals: Twelve adult dogs.

Bursting tension of medium and large canine arteries sealed with ultrasonic energy or suture ligation.

Objective: To compare bursting tension of arteries > or =3 mm in diameter sealed with ultrasonic energy (UE) with arteries ligated with suture.

Study Design: Experimental, nested factorial design.

Sample Population: Vascular segments from canine cadavers.
