The fresh chicken feces were obtained from different age 18 healthy chicken, and were not detectedchlortetracycline. The mixture standard solution of CTC and OTC was added in fresh chicken feces at the concentration of 0.5, 1.0 and 4.0ug/ml respectively. The chicken feces were divided to two groups,one were put in the incubator under photophobic condition; another were under the natural illumination.Samples were collected after 0, 0.5, 1, 2, 3, 5, 7, 9, 12 and 15 days, The concentration of chicken feceswas determined by HPLC. According to the theory of degradation kinetics, we fitted the changed trendof concentrations in chicken feces under different time and studied the degradation characteristics ofchlortetracycline in chicken feces.

选取不同日龄健康鸡18只，实验期新鲜鸡粪，，经检测不含四环素类药物，然后加入金霉素标准液，使得各样品中制得的相应药品的浓度为0.5ug／mL、1.0ug／mL、4.0ug／mL，分为两个实验组，第1组放入培养箱中避光黑暗条件下；第2组置于室外自然光下，定时取样，取样时间为0、0.5、1、2、3、5、7、9、12和15d，鸡粪中药物的浓度用本实验建立的高效液相色谱法测定，根据药物降解动力学原理，对鸡粪中药物的浓度随时间的变化趋势进行曲线拟合，研究金霉素在环境鸡粪中的降解动态规律。

Experiment conclusions ①The expression and activation of MARCKS and p-MARCKS were elevated in brain under the condition of acute ischemia, suggesting that over expression of MARCKS transudation pathway might play an important role in brain ischemia.②Treatment with Qingnao Pilular could inhibit the over expression and activation of MARCKS; MARCKS signal transduction pathway could be novel target for the treatment of acute ischemia.

2实验研究结论①在缺血易损区MARCKS及p-MARCKS表达与活化明显增强，提示MARCKS蛋白过表达和活化与脑缺血损害的发生密切相关；②清脑滴丸可以调节脑缺血易损区MARCKS的过表达与活化，MARCKS信号转导通路可能是脑缺血保护治疗的新靶点，为熄风清热、化痰活血法治疗急性缺血性脑血管病提供了一定的理论和实验基础。

实验结果显示运用微波技术从三白草中多糖提取速度加快；以葡萄糖氧化酶法进行多糖含量测定，为多糖含量测定方法寻找一种新的简便的途径；药理实验说明三白草中的多糖可使四氧嘧啶型糖尿病兔体内血糖值降低，超氧化物歧化酶的活力增强，丙二醇下降。

Results In static phantom studies, the percent error of mean activity obtained by Carson's method was reduced to about 9 %, and it is less than that of image-derived method using maximum likelihood expectation maximization (about 14 %). In simulated dynamic phantom studies, the vessel component could be extracted using ICA in image and sinogram domain. In sinogram domain, the six components extracted by ICA could be obtained quickly.

在静态物理假体实验结果来看，使用Carson's method计算出感兴趣区域活性的百分比误差( 9%)比直接从影像取得活性的百分比误差( 14%)来得小；从数位模拟动态假体实验结果来看，独立成份分析法运用在影像空间或是弦波图空间上，都可以将血管分离出来，但从弦波图空间上得到各个独立成份相对於影像空间就快得多；imageICA和sinogramICA计算出的输入函数的标准化均方根误差分别是0.57和0.28。
