Photobiomodulation effect in tumoral necrosis factor-alpha(TNF-α) on the viability of random skin flap in rats.

The aim of this study was to investigate the effect of red laser (660 nm) photobiomodulation (PBM) with different energies on tumor necrosis factor-alpha(TNF-α) expression for random skin flap viability in rats. Twenty-four Wistar rats were divided into three groups: sham group (SG), PBM laser group with an energy dose of 0.29 J (0.

Collagen Fibers in the Healing Process of Rat Achilles Tendon Rupture Using Different Times of Ultrasound Therapy.

The aim of this study was to evaluate the organization of collagen fibers in the healing process of rat Achilles tendon rupture using different times of ultrasound therapy (TUS). Forty Wistar rats were selected. Among these, 32 were submitted to total and divided into 5 groups: control group (CG,  = 8), without tenotomy or any treatment; tenotomy group ( = 8), with tenotomy and without treatment; TUS groups-TUS3 ( = 8), TUS4 ( = 8), and TUS5 ( = 8)-submitted to tenotomy and treated with TUS for 3, 4, and 5 min per effective radiating area (ERA), respectively.

Manual lymphatic drainage and therapeutic ultrasound in liposuction and lipoabdominoplasty post-operative period.

Background: Physiotherapy in the plastic surgery post-operative (PO) is essential to provide means for an adequate and fast recovery as it restores function through the use of physiotherapeutic procedures.

Aim: The aim of the following study is to verify the effects of the association between the manual lymphatic drainage and the therapeutic ultrasound on pain, oedema and the tissue fibrosis in liposuction and lipoabdominoplasty PO.

Design: This is a clinical trial prospective.

The effects of different doses of 670 nm diode laser on skin flap survival in rats.

Purpose: To investigate the effects of different low-level laser therapy (LLLT) doses on random skin flap rats.

Methods: Forty Wistar rats were randomly divided in four groups. The control group (CG) was not irradiated.
