    ABSTRACT: 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. 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. 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). 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.

    ABSTRACT: To investigate the optimum phase and dose of pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) on the differentiation and mineralization of osteoblast (OB). METHODS (OB) was isolated from the skull of 10 newly born SD rats aged 1 to 2 days by means of Trypsin-collagenase digestion. After the OB was identified, different kinds of pharmaco-serum of diabetic rats fed with inactive Qianggubao decoction ([Chinese characters: see text]) of different phase (rats were fed with medicine three days or five days after last fed with medicine one hour or three hours) and concentration (5%, 10%, 20%) were added to the OB and incubated. After 7 days and 18 days of culture,the effects of the differentiation and mineralization of osteoblast were detected. The secretion of ALP and formation of mineralized nodules of osteoblast in the different doses of pharmaco-serum groups were almost the same as that of normal control group, but were superior to that in the model control group. And the group with concentration of 20% pharmaco-serum was the best in the secretion of ALP and formation of mineralized nodules of osteoblast. As to the phases of pharmaco-serum, the best one on the differentiation and mineralization of osteoblast was the serums from diabetic rat-model fed with Qianggubao decoction ([Chinese characters: see text]) three days or five days, after one hour of last fed with medicine. The pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) can promote the differentiation and mineralization of osteoblast. Allow for time and the cost of experiment,we presume that pharmaco-serum of diabetic rats fed with Qianggubao decoction ([Chinese characters: see text]) three days, after one hour of last fed, with concentration of 20% and not-inactivation is the optimum on the differentiation and mineralization of osteoblast.
