Photobiostimulation effect on diabetic wound at different power density of near infrared laser.

The photobiostimulation effects of near infrared 808 nm diode laser irradiance on diabetic wound were investigated. 120 rats were induced with diabetes by streptozotocin injection. Full thickness punch wounds of 6mm diameter were created on the dorsal part of the rats.

The effect of CO2 laser treatment on skin tissue.

Background/objective: The aim of this study was to evaluate the effects of multiple pulses on the depth of injury caused by CO2 laser in an in vivo rat model.

Methods: A 10 600-nm CO2 laser was applied to rat skin, with one side of the rat dorsal skin being exposed, leaving the other side as a control.

Results: All of the various laser pulses tested led to gradual loss of epidermal thickness as well as a dramatic increase in thermal damage depth.

Combination of Er:YAG laser and CO2 laser treatment on skin tissue.

Skin is the most important organ in our body, as it protects us from external environmental effects. Study the ability of the skin to stretch and the histological examinations of irradiated tissues have significant values in scientific and medical applications. Only a few studies have been done to study the correlation between epidermis ablation and the changes that occur at dermal levels when using dual lasers in ablative resurfacing mode.
