Different saccharides and metal ions had different effects on Hemagglutination.

不同的糖、金属离子对凝集活性的影响不同，0.02mol／L EDTA可抑制全部凝集素的生物活性。

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。

Methods: Three polypeptides were synthesized based on the bioinformatics analysis of the CMTM7 and coupled with keyhole limpet hemocyanin. Balb/c mice were immunized with these mixed CMTM7 polypeptides.

According to the bone apposition events at the interface, we measured the osteoblast attachment rate with the hemocytometer, the osteoblast growth curve with modified MTT method, the ALPase activity and protein content of cellular layers with modified kinetic method and modified Coomassie'method respectively, and osteocalain content in the cell medium with RIA , at different levels of cell responses, as osteocompatibility indexs.

根据骨内种植体界面的骨愈合过程，分别从成骨细胞反应的不同层次选择了细胞贴壁率、细胞生长曲线、细胞层ALPase活性和蛋白质含量以及细胞培养液中骨钙素的含量作为体外评价材料骨性生物相容性的指标。采用细胞计数板计数法测定细胞贴壁率，采用改良MTT法测定细胞生长曲线。
