Studies, which evaluated the effects of 632.8nm and 780nm laser irradiation on Schwann 1 and nerve cell 2 cultures and injured peripheral nerves of animals 3-7 showed positive results. Laser phototherapy induces Schwann cell proliferation 1 and affects nerve cell metabolism and induces nerve processes sprouting 2. Laser phototherapy significantly improves recovery of the injured peripheral nerv...

The Authors discuss their experience in treating non-responder vitiligo patients with a UVA-1 laser. Laser Alba 355® is an innovative device of target UVA - 1 phototherapy. The present report suggests that UVA1 laser could be an applicable therapeutic option in patients with vitiligo, also for the ones who did not respond to the more conventional phototherapies.

Effects of phototherapy using low-level lasers depend on irradiation parameters and the type of laser used. The aim of the present study was to evaluate the effect of phototherapy on the proliferation of cultured C2C12 myoblasts under different nutritional conditions using low-level GaAlAs and InGaAlP lasers with different parameters and incubation periods. C2C12 cells cultured in regular and n...

The kinetics of photooxidation tetrahydrobiopterin was investigated, the quantum yields formation dihydropterin dimers were calculated when using a xenon lamp, tunable UV laser and LED as radiation sources. A comparative analysis effectiveness these sources for process allowed us to conclude that most effective purposes vitiligo phototherapy are, apparently, with emission maxima in region 325 n...

BACKGROUND The role of phototherapy on neutrophils has not been reviewed previously. This novel and non-invasive therapeutic approach is of particular interest for potential use in the treatment of pathologic processes in dermatology and infectious diseases in which neutrophils are the primary culprit. OBJECTIVES The primary aim of this study was to systematically review the role of photother...

OBJECTIVE Laser phototherapy has been widely used to relieve pain for more than 30 years, but its efficacy remains controversial. To ascertain the overall effect of phototherapy on pain, we aggregated the literature and subjected the studies to statistical meta-analysis. METHODS Relevant original studies were gathered from every available source and coded. Articles that met preestablished inc...

BACKGROUND AND OBJECTIVES Little is known about the intracellular response of epithelial cells to phototherapy. The aim of this in vitro study was to analyze the effect of phototherapy with low-energy lasers with different wavelengths and powers on cultured epithelial cell growth under different nutritional conditions. STUDY DESIGN/MATERIALS AND METHODS Epithelial cell cultures (Vero cell lin...

BACKGROUND UV-blocking contact lenses were evaluated to determine if they could provide adequate ocular protection during narrowband UVB phototherapy treatment. Theoretical safe exposure durations for the crystalline lens, cornea and conjunctiva were determined. METHODS A Cary 500 spectrophometer generated transmittance data for six UV-blocking and two non-UV-blocking contact lenses. An IL-17...

308nm xenon-chloride excimer laser, a novel mode of phototherapy, is an ultraviolet b radiation system consisting of a noble gas and halide. the aim of this systematic review was to investigate the literature and summarize all the experiments, clinical trials and case reports on 308-nm excimer laser in dermatological disorders. 308-nm excimer laser has currently a verified efficacy in treating ...
