Clinical, thermographic, and tensiometric evaluation of rat cutaneous wounds treated with collagen gel associated with F18 bioactive glass.

Purpose: To evaluate the association of collagen gel with F18 bioactive glass (BG) in the healing of non-contaminated cutaneous wounds induced in healthy Wistar rats.

Methods: One hundred twelve adult and healthy Wistar rats were randomly divided into four groups (n = 28): saline solution (0.9%); healing ointment based on allantoin and zinc oxide; collagen gel; and association of F18 BG powder and collagen gel.

Morphogeometric Evaluation of the Left Ventricle and Left Atrioventricular Ring in Dogs: A Computerized Anatomical Study.

In veterinary, there is scarce availability of morphogeometric studies in normal and remodeled hearts; furthermore, ventricular geometry acts as an indicator of cardiac function. It is a highly necessary field of knowledge for the development of therapeutic protocols, especially surgical ones. The objectives of this study were: to obtain measurements of the left atrioventricular valve ring and left ventricle, to analyze the proportionality between the segments of the left cardiac chamber of normal hearts and to describe reference values for morphogeometric analysis of the left ventricle.

Fibrosis in canine transmissible venereal tumor after chemotherapy with vincristine.

The canine transmissible venereal tumor is type of transmissible cancer that occurs naturally through allogenic cellular transplants. Commonly diagnosed in the genital area of sexually active dogs, the tumor typically responds well to vincristine sulfate chemotherapy, although there are cases of resistance to the drug correlated with the tumoral phenotype. We describe herein a case of fibrosis in an area affected by the tumor in a dog after vincristine chemotherapeutic treatment that was associated with an idiosyncratic reaction to the drug.

Simulated keratometry and central corneal thickness measured in cats by autokeratometer, ultrasonic pachymeter, and Galilei G6™.

Objective: The aims of this study were to compare the central corneal thickness (CCT) measured by an ultrasonic pachymeter (SP-100, Tomey, Japão) versus the Galilei G6™ (Ziemer Ophthalmics System AG, Port, Switzerland) and to compare the simulated keratometry (SimK) measured by an autokeratometer (KM 500 Nidek) versus the Galilei G6™.

Animal Studied: Eighteen mixed-breed cats, 10 males, and eight females, aged between 18 and 48 months, were evaluated (n = 36 eyes).

Procedure(s): The cats were manually restrained using a blanket.

Dual-Scheimpflug-Placido-disc corneal analysis in cats.

Objective: To evaluate the corneal topography and tomography of cats using a dual Scheimpflug and Placido disc device.

Animal Studied: Sixteen mixed-breed cats (32 eyes).

Procedure(s): Cats were sedated using meperidine (4.
