Effects of Laser Acupuncture on Longitudinal Bone Growth in Adolescent Rats
Figure 2
Effects of laser acupuncture on zone-specific growth within the growth plate. Representative proximal tibia section from normal rat (a) is shown. The tissues were stained with toluidine blue in which cartilage is pink. Resting zone (RZ), proliferative zone (PZ), and hypertrophic zone (HZ) are designated. Scale bar = 100 μm. The length of the entire growth plate and the length of the proliferation zone and the hypertrophic zone were measured separately using image processing software (b). CONT, control group; LA, laser acupuncture group. Each value is the mean ± SEM. *** versus control group.
