LLLT / Photobiomodulation cures acute thrombocytopenia in mice

Zhang et al showed that whole body 810nm laser 100mW/cm2, 30J/cm2 cures acute thrombocytopenia in mice.

Thrombocytopenia is a common hematologic disorder that is managed primarily by platelet transfusions. They showed that noninvasive whole-body illumination cures acute thrombocytopenia triggered by g-irradiation within 2 weeks in mice, as opposed to a 5-week recovery time required in controls.

The low-level laser (LLL) also greatly accelerated platelet regeneration in the presence of anti-CD41 antibody that binds and depletes platelets, and prevented a severe drop in platelet count caused by a common chemo-therapeutic drug.

They conclude: this safe, drug-free, donor-independent modality represents a paradigm shift in the prophylaxis and treatment of thrombocytopenia.

Laser Treatment Halts Oral Mucositis in Its Tracks

Published article by Fran Lowry on Medscape. May 01, 2015.

Spa-like treatment with a cool, low-level laser, similar to that use for wrinkles, vanquishes oral mucositis, one of the most debilitating toxicities of cancer therapy.

“I have been an oncology nurse for over 25 years, and in those 25 years, there has been nothing that helps prevent or is effective against the treatment for oral mucositis, until now,” said Annette Quinn, RN, MSN, from the University of Pittsburgh Cancer Institute.

“Patients say they rank it higher than nausea and vomiting when it comes to adverse side effects, especially because we have good medications to control nausea and vomiting. But the low-level laser works better than we could have hoped,” Quinn … Continue reading

Masters graduate found LED therapy had positive effect on muscular performance

Tom Hemmings, a Masters graduate student at Georgia Southern University

Great news, Tom Hemmings, a Masters graduate student at Georgia Southern University, found that LED therapy had a positive effect on muscular performance. THOR helped Tom decide on a thesis topic in December 2013, which he completed this past week.

The study itself identified the effects of various dosages of LED on the total repetitions performed during an eccentric leg extension. The dosages of 60 seconds and 120 seconds on each point were found to significantly increase repetitions when compared with the placebo trial.

This study suggests that LED can enhance muscular performance when … Continue reading
