Abstract Externally visible growth of the body is the result of proliferation of chondrocytes and longitudinal bone growth. The effects of the Korean herbal medicine, Jaoga‐Yukmiwon ® , on the growth of adolescent rats were investigated in the present study. The proliferation ratio of chondrocytes was calculated from 5‐bromo‐2′‐deoxyuridine incorporation during DNA synthesis. The 5‐bromo‐2′‐deoxyuridine incorporation ratio of the control group was 21.1 ± 3.5%, and Jaoga‐Yukmiwon ® administration markedly increased the ratio to 34.5 ± 4.6% ( p < 0.05). The bone formation rate of longitudinal bone was estimated by labelling with tetracycline, which binds to newly formed bone. The bone formation rate in the tibia of Jaoga‐Yukmiwon ® ‐administered rats was increased to 405.1 ± 4.3 µm ( p < 0.05) from 292.2 ± 11.8 µm (control value). The height of the growth plate in the administrated rats was increased to 614.6 ± 10.0 µm ( p < 0.05) from 552.3 ± 17.1 µm. The bone morphogenetic protein‐2 immunostaining in the growth plate was also increased. These results suggest that Jaoga‐Yukmiwon ® may promote longitudinal bone growth during the developmental period. Copyright © 2003 John Wiley & Sons, Ltd.
