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.

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 told Medscape Medical News.

Nurse personal experience + 32 trials (1505 patients) treated with LLLT for Oral mucositis presented at Oncology Nursing conference, read full article on PracticeUpdate.
April 23, 2015–Orlando, Florida–Low-level laser therapy has been shown to reduce the incidence and severity of oral mucositis significantly in patients undergoing chemoradiotherapy for head and neck cancer or stem cell transplantation. This result of an analysis of 32 prospective trials including 1505 patients was presented at the 40th Annual Oncology Nursing Symposium from April 23 – 26 in Orlando, Florida.
Annette Quinn, RN, MSN, of the University of Pittsburgh Cancer Institute, explained that oral mucositis is one of the most debilitating toxicities of cancer therapy. Nearly all patients with head and neck tumors treated with chemoradiotherapy, and 75% of those undergoing stem cell transplantation with total body irradiation experience some degree of oral mucositis. “Over the last decade,” said Ms. Quinn, “the prevalence of oral mucositis has risen due to new chemotherapy, the introduction of targeted agents, and the delivery of higher doses of radiation.”
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 applying the THOR laser prior an exercise bout.

The VA, Boston University and Harvard Medical School published the results of a Transcranial LLLT (LED) pilot study on mild Traumatic Brain Injury (TBI). Incredibly; TBI is a leading cause of death and disability among children and young adults in the United States. Each year an estimated 1.5 million Americans sustain a TBI, 50,000 people die as a consequence, 230,000 are hospitalized and an estimated 5.3 million currently live with a permanent TBI-related disability (because there is no cure). This study showed significant improvement in Executive Function, Verbal Learning, Long Delay Free Recall and fewer post-traumatic stress disorder (PTSD) symptoms. Participants and family reported better ability to perform social, interpersonal, and occupational functions. This was a small pilot study on just eleven patients with chronic mTBI, there was no placebo control group so further studies are necessary to truly establish the effect size.
