Attenuation of morphine withdrawal signs by low level laser therapy in rats
Scientists at AJA University of Medical Sciences, Tehran have shown that LLLT prior to naloxone injection attenuates the expression of withdrawal signs in morphine-dependent rats.

Abstract Objective: To assess the effect of low-level laser therapy (LLLT) on viability of mast cells of the transverse rectus abdominis musculocutaneous (TRAM) flap. Background Data: LLLT has been recently used on the TRAM flap to stimulate mast cells. Materials and Methods: Eighty-four Wistar rats were randomly divided into seven groups of 12 rats in each: group 1 (sham laser therapy); group 2 received 3 J/cm(2) at one point; group 3 received 3 J/cm(2) at 24 points; group 4 received 72 J/cm(2) at … Continue reading

Laser Prevents Muscle Tissue Damage Induced by Snake Venom
A rat tibialis anterior muscle was injected with venom. Sixty minutes after venom injection, 632.8nm laser (HeNe) was administered at three incident energy densities. They concluded that HeNe laser irradiation at a dosage of 3.5 J cm2 (the lowest “dose” administered in this study) effectively reduced myonecrosis and the neuromuscular transmission blocking effect caused by the snake venom.

LLLT using Light Emitting Diodes research list
Yet another NASA NIR LED therapy paper was published recently showing that LED treatment may be therapeutic to damaged neurons, this time in a Parkinson’s disease model. I thought some of you may not appreciate quite how much research has been conducted with LED’s so here is a list of 43 that I found on PubMed.
Near-infrared light via light-emitting diode treatment is therapeutic against rotenone- and 1-methyl-4-phenylpyridinium ion-induced neurotoxicity.

Parkinson’s disease is a common progressive neurodegenerative disorder characterized by the degeneration of dopaminergic neurons in the substantia nigra pars compacta. Mitochondrial dysfunction has been strongly implicated in the pathogenesis of Parkinson’s disease. Thus, therapeutic approaches that improve mitochondrial function may prove to be beneficial. Previously, we have documented that near-infrared light via light-emitting diode (LED) treatment was therapeutic to neurons functionally inactivated by tetrodotoxin, potassium cyanide (KCN), or methanol intoxication, and LED pretreatment rescued neurons from KCN-induced apoptotic cell … Continue reading
