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.
