The effect of low-intensity therapeutic ultrasound in induced fracture of rat tibiae.

Objective: To analyze the possible effects of low-intensity ultrasound on induced tibia fracture of rats in a dose commonly used in physical therapy treatments.

Methods: Twenty male Wistar rats were divided into two groups with 10 animals each. In the ultrasound group (USG), the animals were submitted to bone fracture and treatment with therapeutic ultrasound (TUS).

Immediate graft histological assay, post pig's liver transplantation.

Purpose: To describe the vascular and tissue histopathological changes in seven sequential experimental liver transplantations in pigs.

Methods: Fourteen female pigs, Sus domesticus species, with body mass between 5 and 8 kg were utilized. After the end of all anastomoses of the graft implantation in the receptor, the animal was monitored for 30 minutes, and at its end one of the biopsies was collected for histological analysis.
