苦味酸

The chromogenic reaction of cetyltrimethyl ammonium bromidewith 2,4,6-tri nitrophenol was studied.

生成的缔合物在4 2 0 nm处有最大吸收，表观摩尔吸光系数为1.6×10 4 L·m ol- 1 ·cm- 1 ，苦味酸浓度在0～12 0μg·m L- 1 范围内符合朗伯-比尔定律，此法可应用于DDNP废水中硝基酚类的测定。

Methods: 15 male New Zealand white rabbits underwen excision of an ellipse and a 0.5 cm×0.5cm defect was made in notal side of tunica albugineand, The animals were euthanized and specimens were harvested at intervals of 2, 6 and 12weeks, The specimens were stained by picrosirius and observed by polarimicroscope.

在15只新西兰兔阴茎背侧切除白膜5mm×5mm造成缺损，分别在术后2，6，12周（每次5只）取材，苦味酸天狼星红染色，偏振光显微镜观察。

The periostea of both experimental and control side of the mandibular ramus were taken and prepared, 2 of each 5 rabbits in a group were prepared for HE stain detection and 3 for proliferating cell nuclear antigen immunohistochemical detection.Results:1, The newly formed bone was detected on the lateral aspect of mandibular ramus after periosteal distraction. The bone was shaped like a hill. It looked very low and was full of holes at postoperative day 28. With the time of consolidation period lengthened, the newly formed bone matured gradually. X-ray examination showed the new bone shaped like a hill. The average values of new bone height at postoperative days 28,35,42 and 56 were 1.86 + 0.15mm, 2.29 + 0.29mm,3.19 + 0.13mm and 4.70 + 0.45mm. Histological examination of both HE stain and picricacid-fuchsin stain showed the increase in the number of osteoblasts and the change in the orientation of collagen fibers and bone trabecula. There were no significant differences between newly formed bone and original bone on the lateral aspect of mandibular ramus at postoperative day 56 histologically.2 Compared with the control side, the distracted periostea proliferated obviously under the microscope, and the number of periostealcells increased with satiation of cellular nuclear per unit area. The images of PCNA immunohistochemical stain of periosteum showed that the experimental periosteum proliferated obviously after distraction compared with the control side.

结果：骨膜牵张成骨的实验研究南京医科大学硕{学位论文l、骨膜牵张后，可见下领升支外侧的骨皮质上有新骨形成，新骨呈山峰状凸起，术后第28天的新生骨较低平，多孔隙，随着固定时间的延长，新骨逐渐成熟；下领升支前后向切线位X线投照显示新骨呈山峰样隆起；经测量，术后第28、35、42和56天组平均新生骨厚度分别为x.86士0.15mm、2.29士0.29mm、3.19士0.13mm和4.70 土0.45mm；脱钙骨组织的HE染色和不脱钙骨组织的苦味酸一品红染色的组织学观察均显示了新生骨在成骨细胞数量上的增长，以及胶原纤维和骨小梁排列方向上的变化，术后第56天的新生骨在组织学上与原升支骨组织已无明显区别。2、HE染色显示，与对照组相比较，实验侧骨膜增生明显，细胞间排列紧密，单位面积内骨膜细胞数增多，细胞核饱满；骨膜PCNA 免疫组化染色显示，与对照侧相比较，实验侧骨膜在牵张后出现了明显的增生迹象，PCNA阳性细胞分布紧密，单位面积内阳性细胞数较对照组多，靠近骨表面的骨膜中的阳性细胞数更多而且分布更为紧密。
