The changes of nutrition in milk treated with different technologies are also determined. Results showed that, 1 higher pressure, longer holding time and more alternative times favour a larger destruction of microorganisms; 2 the combined effect of hurdle technology and pressure on the destruction of microorganisms in fresh raw milk is more effective than only using pressure treatment, among which the effect of ε-polylysine on inactivation of microorganism in fresh raw milk is more effective than that of Nisin with the same concentration of 100mg/L; 3 the whole proteins in milk treated by the different types of sterilization have been detected by SDS-PAGE electrophoresis, and comparing with the whole proteins' electrophoretogram of fresh raw milk, we found that the first spectrum band near the negative pole was disappeared and the colours of the second spectrum band was tint in UHT, pasteurism and 500MPa treated milks, which was suggested that some proteins' subunits were dissociated, but the 400MPa treated milk showed the similar eletrophoretogram with the fresh raw milk; 4 the loss of threonine, VA and VC in high pressure treated milk was more less than those in pasteurism treated milk, in particular threonine and VA were almost retained, and the contents of VB1 and VB2 in the former are also more than that in the latter; 5 high pressure treated milk had longer shelf life than pasteurism treated milk, extending the sale semidiameter of milk.

压力越高，保压时间越长，交变次数越多，杀菌效果越好；2）采用栅栏技术对牛乳中的微生物具有更有效的杀菌作用，其中相同浓度的（终浓度100mg/L）ε-聚赖氨酸较Nisin具有更强的杀菌效果；3）利用SDS-PAGE电泳研究了不同杀菌方式对牛乳总蛋白的影响，发现经UHT、巴氏和500MPa交变处理的牛乳与生鲜牛乳相比其总蛋白电泳图谱靠近负极方向第一条谱带消失，第二条谱带颜色变浅，由此推测经上述处理后牛乳中有一些蛋白质的亚基发生了解离，而经400MPa交变处理的牛乳与生鲜牛乳的总蛋白电泳图谱相似；4）超高压牛乳营养成分与生鲜牛乳相比，苏氨酸、VA、VC在超高压处理中受到的破坏明显比巴氏杀菌小得多，特别是苏氨酸和VA几乎完全被保留下来，而VC含量也要比巴氏奶高出25%以上，对于VB1、VB2，检测数据也表明，超高压灭菌对其破坏要比巴氏灭菌小，其含量分别比巴氏杀菌牛乳高出9.5%和2.6%；5）与巴氏杀菌乳相比，超高压杀菌有助于延长牛乳的保质期，扩大牛乳的销售半径。

For the purpose of research on relationship between liquid crystal phenomena and blood compatibility, the propionic, n-butyric esters of hydroxypropyl cellulose were prepared with hydroxypropyl cellulose and propionyl chloride/ butyryl chloride. The reaction conditions and phase behavior have been studied. The results show that the reaction time, temperature and amount of propionyl chloride have effect on content of propionyl, and the amount of proionyl chlorideis more obvious than the other factors.

液晶态的血液相容性是目前抗凝血材料研究的一个新领域，本文是在一系列液晶态材料血液相容性研究的基础上以羟丙基纤维素和丙酰氯为原料合成羟丙基纤维素丙酸酯和羟丙基纤维素丁酸酯两种液晶高分子化合物，并对其合成条件和相变行为进行了研究，结果表明：反应时间、反应温度和酰氯的用量均对产物中的酰基含量有影响，其中以酰氯用量影响最为明显。

The results show that both conformations of prolyl peptide bond are not easy to transit from each other supporting the opinion that both of the BPP's bio-characters are from its conformations separately. And the function of BPP may not lie on a conformation. The other peptide bond conformations also have influence.

结果表明，脯氨酸肽键构象不易发生互变，无论哪种构象均不存在向另一种构象转变的趋势，从侧面支持了BPP具有的两种稳定的生物学作用是来自于肽键的不同构象的观点，而且BPP的生物学作用可能也不是取决于某一个肽键构象，其它脯氨酸肽键构象对其活性也存在影响。
