ABSTRACT OBJECTIVE:To investigate the effects of Ligustri lucidi Fructus extract on the differentiation of osteoclasts and the
proliferation of osteoblasts. METHODS:Rabbit primary bone marrow cells were induced with 1a,25-Dihydroxyvitamin D3 to
obtain osteoclasts. After treated with low-dose,medium-dose and high-dose of L. lucidi Fructus ethanol and water extract(both 2,
20,200 mg/L),TRACP activity determined method was used to detect the activity of TRACP in cell lysis solution and the number
of TRACP positive cells. The number of celluar bone resorption lacunae and the percentage of bone lacunae area were detected by
toluidine blue staining. Osteoblasts were obtained by L-ascorbic acid,β-sodium glycerophosphate and dexamethasone-induced
subcloning 14 of cranial parietal anterior osteocytes in mice. MTT assay and APK activity assay were used to detect relative
proliferation rate of cells and the activity of APK. RESULTS:After treated with different doses of L. lucidi Fructus extract,the
number of TRACP positive cells,the number of bone resorption lacunae and their area were changed in varying degrees. TRACP
activity,the number of its positive cells,the number of bone resorption lacunae and the percentage of bone lacunae area in
different dosage groups of L. lucidi Fructus ethanol extract and high-dose of water extract;the TRACP activity,the number of its
positive cells and the percentage of bone lacunae area in L. lucidi Fructus water extract medium-dose group were decreased
significantly,while the number of bone resorption lacunae in L. lucidi Fructus water extract low-dose group was increased
significantly(P<0.05 or P<0.01). The relative proliferation rate of cells in L. lucidi Fructus extract low-dose and medium-dose
groups and APK activity of cells in extract groups were significantly increased,while the relative proliferation rate of cells were
decreased significantly in L. lucidi Fructus ethanol extract and water extract high-dose groups (P<0.01). CONCLUSIONS:L.
lucidi Fructus extract can inhibit TRACP activity of osteoclasts,change the bone resorption function of osteoclasts and the
proliferation behavior of osteoblasts and increase APK activity of osteoclasts.
