Study on Mechanism of Effects of Total Flavone of Rhizoma Drynariae on Osteoblasts Cultured in Vitro / 中华中医药杂志

ABSTRACT

Objective: To study the mechanism of effect of total flavone of rhizoma drynariae in groups with different dosage on osteoblasts cultured in vitro. Methods: To culture osteoblasts with UMA-106-01 osteoblast strain and to observe the activity of ALP and the endosmosis of 3H-TdR. Results: The total flavone of rhizoma drynariae increased the activity of ALP in cells cultured with UMR-106-01 strain. The ALP activities correspondingly changed in the 24h, 48h and 72h, which related to dosage effect and time effect. Among them, the activity in the 48h is the most ideal one. And the amount of endosmosis of the total flavone of rhizoma drynariae to 3H-TdR increased more remarkably in the 48h than that in the 24h and it also related to the time effect. Conclusion: The total flavone of rhizoma drynariae can promote the differentiation and multiplication of osteoblasts.
