The toxicity and the osteogenous ability on the surface of PCHA: the toxicity was examined by coculture with PCHA to record growth of cells with MTT method. The osteogenous ability was investigated by observation of the formation and growth of cells on the surface of PCHA bone cement.

PCHA毒性检测和表面细胞活性的观察：将PCHA浸出液与骨髓基质细胞共同培养，通过MTT比色描记细胞生长曲线，快速判定制孔剂添加后PCHA的毒性反应；将PCHA制成标准试件，与骨髓基质细胞共同培养，观察细胞形态和生长活性。

In bioconv ertion experiment for spiramycin of No.5 transformant, the bioconversion product was analysed with TLC, bioautography, HPLC and mass spectrum.Results showed that the bioconvert product is propionyspiramycin. Propionyl acylase gene was l ocolized on 0.53 kb insert DNA fragment of recombinant pasmid pLJM95. Analysis result of DNA sequence showed that content of G+C is 68.2% for 0.53kb insert DNA fragment .

以No.5转化子对螺旋霉素进行生物转实验，其转化产物经薄层层析，生物显迹，高压液相色谱及质谱分析表明，与标准丙酰螺旋霉素一致，这说明 No.5 转化子具有将螺旋霉素生物转化为丙酰螺旋霉素的能力，丙酰化酶基因位于重组质粒，pIJM95 0.53kb 插入DNA片段上。

Moreover,it was demonstrated that the threesubstances,E,DE and DA,increased dramatically and quickly after LPS treatment.Also,it was revealed that the changes of three substances were more quickly than thechanges of the above mentioned APPs during the same LPS treatment.Thesesuggested that the three substances existed as neurotransmitter.The presence and thechange of the CAs in amphioxus after treated with LPS indicated the evolutionaryexistence of CAs and acute phase response in the protochordate lineage.

第四，我们用高效液相色谱法(High Performance Liquid Chromatography，HPLC)，探讨了LPS感染文昌鱼儿茶酚胺类神经递质的变化，优化了同时测定文昌鱼体液中NE、E和DA三种CAs的HPLC方法，并首次发现，文昌鱼体液中同时存在NE、E、和DA三种CAs物质，其中，E在文昌鱼中首次报道，这三种物质在LPS感染文昌鱼后浓度升高非常明显，与同期的APPs相比变化更为迅速，也体现了神经递质的主导作用，文昌鱼的CAs系统也具有了类似脊椎动物CAs系统的功能，可以初步判断CAs系统的进化源头由脊椎动物可推回到头索类。

And based on the mass spectrometry raw data, protein identification was performed by application of the Mascot or SEQUEST search program, respectively.

利用质谱分析得到的原始数据，MALDI-TOF通过Mascot软件搜索，高效液相色谱-质谱联用仪通过SEQUEST搜索SWISS-PROT的人非冗余蛋白质序列数据库。
