"The results indicated that type I and type III mRNA levels were markedly increased at days 17 and 28 of the healing in wounds ...
"A comparison of the He-Ne and He-Cd laser therapy in this study revealed from 1.57 and 7.84% difference of wound healing acceleration. The acceleration ...
"The treated animals presented a larger expression of collagen and elastic fibers, although without statistical significance (p > 0.05). Treatment with a dosage of ...
"The mean time required for complete closure in control group was 7 days while irradiated test wounds took only 5 days to heal (P ...
"820 nm is the most effective wavelength"
"laser and non-coherent lamp are equivalent"
"LLLT stimulates wound contraction in susceptible mouse strains but the mechanism remains uncertain."
"It was shown that irradiation with laser accelerated the healing of wounds in all cases. The exposure to laser radiations in the red (1.5 ...
"It is concluded that nutritional status influenced the progression of the healing process as well as the quality of the healed tissue, and that ...
"The combined application of red and infrared lasers resulted in the most evident systemic effect on the repair of skin wounds produced in rats."
"The results showed that low-level laser therapy improved wound healing. Besides, our results showed that low-level laser therapy significantly increased the activities of complexes ...
"In conclusion, LLLT, by the method we used, improved wound healing in the non-steroid laser-treated rats, but it was useless after corticosteroid treatment."
"Quantitative histopathological analysis confirmed the results of the qualitative analysis through histological microscope slides. When comparing tissue components (inflammatory cells, vessels and fibroblast/area), we ...
LLLT with a He-Ne laser was found to promote the healing of operative wounds in the present rat model, in which the most favorable ...
"Laser was effective in reducing swelling and polymorphonuclear cells and accelerated tissue repair, even in the presence of dexamethasone."
"The right circularly polarized light and linearly polarized light promoted the process of wound healing by increasing the proliferation of fibroblasts, and the right ...
"Mice exposed to 670-nm red light showed significantly faster healing than control mice. High, medium, and low fluxes of light were all effective after ...
"As compared to nonirradiated control wounds, laser stimulation shortened the inflammatory phase as well as accelerated the proliferative and maturation phase, and positively stimulated ...
"Thus, laser photobiomodulation was able to induce several modifications during the cutaneous healing process, especially in favoring newly-formed collagen fibers to be better organized ...
"According to our findings, the group exposed to light therapy showed statistically significantly faster epithelialization seen on days 10 and 15 post-wound compared to ...
"Illumination substantially influenced wound healing. Blue light significantly decreased wound size on day 7, which correlated with enhanced epithelialisation. Light also affected mRNA expression. ...
"We suggest that He-Ne laser promotes collagen formation and restores the baseline cellularity after pharmacological inhibition, indicating new perspectives for laser therapy aiming to ...
"LLLT acted as a biostimulatory coadjuvant agent balancing the undesirable effects of nicotine on wound tissue healing."
"The results showed an improvement in the wound healing reflected by the reduction in wound size and increased collagen synthesis. Moreover, a significant reduction ...
"Results show that the 60 J/cm2 laser was more effective in stimulating angiogenesis. In addition, the 60 J/cm2 and the 30 J/cm2 laser were ...
"The analysis of the biochemical parameters and histopathological parameters of the wounds showed that the laser-treated group healed faster and better as compared to ...
"The effect of polychromatic LED therapy in oval full-thickness wound-healing in the diabetic model with the use of 5 and 10 J/cm(2) is promising. ...
"On days 3, 7, and 14, the proliferation of blood vessels in all irradiated groups was superior in comparison to those of the control ...
"The ASCs and ASCs+LLLT groups stimulated wound closure and histological skin regeneration. The ASCs+LLLT group enhanced the wound healing, including neovascularization and regeneration of ...
"Irradiation with 660 nm, 80 mW at an energy density of 3.7-5.0 J/cm² each day for 7 days caused the maximal stimulation of healing ...
"The results show that the use of low level laser therapy and ICOX2 in isolation increases epithelial cells, but only low level laser therapy ...
"LPBM resulted in reduced inflammation and an increase in both fibroblast proliferation and collagen deposition."
"It was concluded that irradiation with light of both laser and LED decreases the level of oxidative stress in wound fluid and that radiation ...
"The average number of myofibroblasts was statistically significantly higher in the irradiated group than in the non-irradiated group on the eighth (p = 0.001) ...
"Both red lasers significantly increased wound TS at selected parameters. Whereas the 635 nm laser significantly improved wound healing by using the higher power ...
"We found that LLLT was able to slightly reduce the intensity of the inflammatory reaction as well as to enhance substantially the epithelization process ...
"Laser irradiation with 0.03J/cm(2) significantly decreased the maximum load for wound repair in healthy rats (p=0.015). Laser irradiation with 0.2J/cm(2) significantly increased the maximum ...

"A significant increase in hydroxyproline and glucosamine levels was observed for the 2 J cm(-2) irradiation group compared with the controls and other treatment groups. In ...
"LLLT alone accelerates post-surgical tissue repair and reduces edema and the polymorphonuclear infiltrate even in the presence of dexamethasone."
"Histological analysis showed that control subjects had a lower amount of blood vessels when compared with irradiated subjects. Irradiated subjects had more advanced resolution ...
