Calcium sulfate has been used for bone regenation in oral medicine. Osteopontin, a marker molecule, expressed by osteoblast, plays multiple roles in human body. However, the effect of calcium sulfate on osteopontin expressed in osteoblasts is unclear. In this study, U-2 osteosarcoma osteoblastic cells were cultured in 0, 0.5, 1, or 10 μM calcium sulfate hemihydrate. There was no effect in the proliferation of cells, suggesting that calcium sulfate up to 10 μM is biocompatible. The cells and conditioned media were collected for analyzing mRNA and protein levels of osteopontin by reverse-transcription polymerase chain reaction and Western blot, respectively.

硫酸钙用於口腔医学中的骨头再生已经有多年历史，骨桥素是一种被骨母细胞分泌且在人体扮演重要多重角色的标的分子，然而，硫酸钙在骨母细胞分泌硫酸钙上的影响仍未明朗，在本实验之中，培养U-2骨肉瘤类骨母细胞(U-2 osteosarcoma osteoblastic cells)於0、0.5、1、10 μM的硫酸钙之中，在细胞数目的复制上，四种硫酸钙浓度并无影响，显示出U-2骨肉瘤类骨母细胞培养於10 μM的硫酸钙仍是生物相容性的。

Here pis 1 or 2.In chapter 8. we extend the Runge-Kutta methods to variable delay differentialalgebraic system. It is proved that if the Runge-Kutta method which is algebraicallystable and diagonally stable is consistent with order p , the extended Runge-Kuttamethod with Lagrange interpolation procedure is D_A-convergence with order M. HereM=min{p, u + q + 1 }, and u + q is the degree of Lagrange interpolation polynomial.
