However, whether the human fibroblasts behave in a similar way has not been reported to our knowledge. In the present study fibroblasts collected from human foreskin were cultured in vitro so as to investigate into the fibro blastic osteogenetic role as well as its mechanism.

本实验包括四个部分：1、人皮肤成纤维细胞体外培养成骨的实验研究。2、猪骨形态形成蛋白（pBMP的提取及生物活性测定。3、pBMP对成纤维细胞成骨影响的实验研究。4、成纤维细胞体外培养过程中骨钙素变化。

Results:scutellarin is more rapidly and thoroughly absorbed following intratracheally sprayed to the rat lungs,relative to after peroral administration and pulmonary delivery of scutellarin seemed to eliminate from the intestinal and hepatic first pass metabolism occurred during oral delivery of the drug with the absolute pulmonary bioavailability at the dose of 10 mg/kg against intravenous controls being determined to be about 77%,which was more than 30 folds higher than that given by peroral administration.

结果灯盏乙素溶液经大鼠气管喷雾给药后的绝对生物利用度程剂量线性相关，10mg/kg剂量时F约为77%，是灌胃给药后F的约30倍，并且能够避开首过效应。
