    Abstract:
    OBJECTIVE: To study the effect of inactivated and un-inactivated pharmaco-serum of diabetic rats fed with Chinese herbs Qianggubao decoction on the proliferation of osteoblast cells (OB)cultured in vitro. METHODS: OB was isolated from the skull of newly born SD rats aged 1 to 2 days by means of Trypsin-collagenase digestion and identified by image analysis under inverted microscope, V-G collagen staining, ALP staining, calcification nod staining etc. After the OB was identified, in activated and un-inactivated pharmaco-serum of diabetic rats fed with Qianggubao decoction of ferent phase (rats were fed with medicine 3 days or 5 days after last fed with medicine 1 hour or 3 hours) and concentration (5%, 10%, 20%) were added to the OB and incubated. After determined times, the effects of the proliferation of osteoblasts were detected by MTT analysis. RESULTS: There was significant difference between un-inactivated pharmaco-serum and inactivated pharmaco-serum on the proliferation of osteoblasts, and un-inactivated serum had stronger effects to improve the proliferation of osteoblasts (P < 0.01 or P < 0.05). CONCLUSION: Un-inactivated and inactivation pharmaco-serum of diabetic rats fed with Chinese herbs Qianggubao decoction can influence the proliferation of, and the un-inactivated pharmaco-serum has stronger effects.
