He-Ne Laser on Microcrystalline Arthropathies

Abstract

He-Ne laser treatment in the microcrystalline arthropathy induced in rats by DCPP injection might have an antiinflammatory effect, evaluated by fibrinogen plasma levels and TNF-alpha (inflammatory markers) and by the histopathology regressive process.

Low level laser therapy partially restores trachea muscle relaxation response in rats with tumor necrosis factor α‐mediated smooth airway muscle dysfunction

“…In another rat study, LLLT reduced inflammation in arthropathy and TNF-a levels particularly [38]. We have reproduced these results in a rat model of acute lung inflammation where LLLT also reduced TNF-a levels [37].…”

Inflammatory and Oxidative Stress Markers in Experimental Crystalopathy: Their Modification by Photostimulation

“…The side effects caused by NSAIDs represent 25% of all secondary effects of these drugs, and NSAID use causes 25% of all gastro-duodenal ulcers. 32 In light of the conflicting results published to date, [17][18][19][20][21][22][23][24] it is clear that the use of LLLT to treat rheumatic pathologies requires further study.…”

“…However, although there is much in the literature about the therapeutic effects of low-level laser therapy (LLLT), some of the literature shows contradictory results. [17][18][19][20][21][22][23][24] The process by which LLLT stimulates cellular function is called photostimulation. 25,26 We agree with other authors who study this therapy through experimental research, in an effort to clarify the interactions of light energy with cells and molecules, because these represent an important challenge to the clinician.…”

“…Also, it enhances collagen synthesis [28], decreases the inflammatory markers [29], and increases lymphocytes response [30]. LLLT also causes stimulation of electron transport system leading to enhanced ATP production [31].…”
