Laser increases angiogenesis and with 2.4 J/cm 2 it prevents No analgesia. Slight recovery of cartilage and synovia. None had Decreases bacterial counts; 22 J Laser reduces bacterial Variable degrees of decolonization – 100% at 940 nm, 600 J Laser increases angiogenesis and with 2.4 J/cm 2 it prevents Bactericidal at 260 J/cm 2 ; may be related to desiccation? 45°C Eliminates nail fungus; clear nail

Results bacterial growth Decreases 2 log colony counts (99%) positive bacterial cultures more effect proliferation Reduces/clears bacteria Decreases 2 log colony counts (99%) bacterial growth Decreases 2 log colony counts (99%) reached grows
