OBJECTIVE: To determine the ability of plasma and peritoneal creatine kinase (CK) to predict the presence of a strangulating lesion in horses presented for colic. STUDY DESIGN: Prospective clinical study. ANIMALS: Ten healthy control horses and 61 clinical colic cases. METHODS: Creatine kinase activity was measured in peritoneal fluid and plasma of 10 healthy horses and 61 horses presenting for colic (40 horses with nonstrangulating lesions and 21 horses with strangulating lesions)...

OBJECTIVE: To determine the most secure knot when tied by veterinary students in a ligation model. STUDY DESIGN: Prospective study. SAMPLE POPULATION: Sixteen first-year veterinary students. METHODS: Veterinary students were taught 3 knots: surgeon's, Miller's, and strangle.

OBJECTIVE: To evaluate a prototype dynamic laryngoplasty system (DLPS) in a static airflow model. STUDY DESIGN: Experimental. SAMPLE POPULATION: Ten equine larynges. METHODS: The right arytenoid was fixed in abduction in all specimens. A left-sided laryngoplasty was performed with No. 2 Fiberwire and a FASTakII anchor. Each larynx was tested in a static airflow model. The system was adjusted to a flow rate of 55 L/s and prelaryngeal pressure of 12 mm Hg prior to testing in maximal arytenoid abduction...
