Objective. The goal of this study was to investigate the therapeutic efficacy of 670 nm light-emitting diode (LED) irradiation on the diabetic retinopathy (DR) using hypoxic rhesus monkey choroid-retinal (RF/6A) cells as the model system.Background Data. Treatment with light in the spectrum from red to near-infrared region has beneficial effect on tissue injury and 670 nm LED is currently under clinical investigation for retinoprotective therapy.Methods. Studies were conducted in the cultured cells under hypoxia treated by cobalt chloride (CoCl2). After irradiation by 670 nm LED with different power densities, cell viability, cytochrome C oxidase activity, and ATP concentration were measured.Results. The irradiation of 670 nm LED significantly improved cell viability, cytochrome C oxidase activity, and ATP concentration in the hypoxia RF/6A cells.Conclusion. 670 nm LED irradiation could recover the hypoxia damage caused by CoCl2. Photobiomodulation of 670 nm LED plays a potential role for the treatment of diabetic retinopathy.

Nerve Crush

Tibialis anterior (TA) muscles of rats underwent bilateral peroneal nerve crush (NC) or denervation (D) and were compared with sham-operated (SO) animals to determine the effect of reinnervation on blood flow, mitochondria, metabolites, and muscle performance. After surgery, animals were left for 2, 7, 21, or 42 days (NC and SO groups) or 2, 7, or 21 days (D group; n = 7–11.day-1.group-1), after which TA muscles were stimulated in situ at 1 Hz. alpha-Motoneuron reinnervation of muscle was complete 21 days after NC. Blood flow increased 10-fold above SO values in nonstimulated TA muscle 7 days after NC and D (P < 0.05). By 21 days, blood flow to nonstimulated TA muscle in NC animals returned to SO values but remained elevated (P < 0.05) in D muscle. Thus restoration of neural control of blood flow to resting muscle likely occurred by 21 days post-NC. Blood flow to stimulated muscle was not affected by NC or D, indicating the probable importance of metabolic factors in regulating blood flow during 1-Hz contractions. Cytochrome-c oxidase activity decreased (P < 0.05) below SO values 7 days after NC and D. By 21 days, cytochrome-c oxidase activity in TA muscles of NC animals returned to SO values, while values in denervated TA muscle continued to decrease. Despite these changes, endurance performance of TA muscle was not affected by D or NC at any time. These results suggest that reinnervation processes controlling blood flow and muscle function occur along similar time courses and that muscle blood flow is more closely related to endurance performance than is muscle oxidative capacity under these contraction conditions.
