The multilobular tumor of bone (MTB) is considered as a slow-growth malignant tumor, which generally occurs on the cranium and facial bones of dogs, although it has been reported in other domestic animals. This study presents two cases of MTB in dogs. The first case was manifested in an 8-year-old m...

OBJECTIVE: The aim of this study was to investigate the morphologic and biochemical effects of excess dietary copper in young and adult rats of different sex. METHODS: Adult Fischer 344 male and female rats were given a diet containing 1500 ppm copper for 18 weeks. Young male and female rats were fe...

The aim of this study was to define an experimental model in rabbits for subcutaneous heterotopic ovarian autotransplants and allotransplants in the inguinal region using a microvascular technique to restore endocrine function and ovulation. Forty sexually mature New Zealand white receptor rabbits a...

OBJECTIVE: To determine the effects of chronic exposure to excess dietary copper (Cu) on liver specimens from rats and the effects of dietary selenium (Se) supplementation in experimental Cu toxicosis.

Cutaneous infections caused by Mycobacterium are rare in domestic animals in Mexico. The most affected species is the cat. The present case informs about a case of cutaneous mycobacteriosis in a dog describing its clinical and pathological findings. A similar case had never been reported in dogs unt...

The aim of this study was to establish a reverse transcription-polymerase chain reaction (RT-PCR) for the diagnosis of avian influenza virus in paraffin embedded tissues of experimentally infected animals, and to correlate viral detection by this method with the histological changes. Eight groups of...

The spleen is the most common primary site for hemangiosarcoma in dogs. The tumor is characterized by rapid growth and widespread metastasis, presumably due to both its tissue of origin, the vascular endothelium, and its resultant ready access to systemic circulation. The most common clinical presen...

The aim of this study was to re-establish endocrine and reproductive function in tubal-ovariectomized rabbits using orthotopic tubal-ovary allo-transplants (OT-OA). Fifty-five New Zealand White nonconsanguineous rabbits were used and allocated into five experimental groups: Each group comprised dono...
