When culture condition was changed abruptly from LES medium to RPMI-1640 medium, different reproductive mode including binary fission, ternary fission,multiple fission and gemmation were found after growth retardation of 24 ～ 72 hours. This phenomenon continued less than 24 hours and binary fission remained reproductive mode then.

当从LES培养基突然变为RPMI-1640培养基时，人芽囊原虫出现短时间(48～72h)内生长停滞，随后出现多种形式的繁殖方式，可见较多的二分裂、出芽生殖、三分裂、多分裂、裂体生殖，持续24h后恢复为二分裂为主。

objective to compare four postoperative nasal packing materials.methods total 136 patients,80 cases with chronic sinus it is and under went endoscopic sinussurgery,were randomly packed using four different hae mostasis materials.in which,paraffin gauze group was 40 cases,rapid sorbalgon group 27 cases,merocel group 36 cases and gel knit group 31 cases.the packing materials wereemoved after left for 24 hours to 48 hours.the efficacy of nasal packing materials was asassessed interm of the levels of nasal pain or headache in the leaving period and nasal bleeding after removal of nasal packing.results the in cidence rate of nasal pain or headache respectively was 82.5% in paraffin gauze group,44.4% in merocel,11.1% in sorbalgon and 3.2% in gel knit.the significant statistical difference was observedbetween the four groups (χ2=70.21,p.01).the incidence rate of nasal bleeding after removed was 85%,11.1%,41.7% and 9.7% respectively.the statistical difference was also significant (χ2=54.28,p.01).conclusions the choosing of postoperative na sal packing after functional endoscopic sinus sur gey depends on various factors,gel knit has much advantages and can be used as routine packs after fess.

摘 要］目的：比较四种鼻腔填塞材料的疗效，指导临床选择合适的术后鼻内填塞物。方法：对134例慢性鼻窦炎分别采用凡士林纱条(40例)、藻酸钙纤维(sorbalgon，27例)、膨胀海绵(merocel，36例)和瑞纳凝胶快速止血材料(gel knit，31例)四种材料填塞鼻腔，24 h～48 h取出填塞物，根据填塞后鼻腔胀痛、头痛程度，取出填塞物后鼻腔出血程度等评价疗效。结果：凡士林纱条填塞组，82.5%有鼻腔胀痛或头痛；sorbalgon藻酸钙纤维组11.1%；merocel组44.4%；gel knit组3.2%，四组比较差异非常显著(χ2=70.21，p.01)。取出填塞物后鼻腔再出血分别为85%，11.1%，41.7%和9.7%，四组比较差异非常显著(χ2=54.28，p.01)。结论：鼻内镜手术时，应综合考虑诸方面因素合理选用术后填塞物。瑞纳优势较为全面，可作为鼻内镜手术的常规填塞材料。

秋颂1雾气洋溢、果实圆熟的秋，你和成熟的太阳成为友伴；你们密谋用累累的珠球，缀满茅屋檐下的葡萄藤蔓；使屋前的老树背负着苹果，让熟味透进果实的心中，使葫芦胀大，鼓起了榛子壳，好塞进甜核；又为了蜜蜂一次一次开放过迟的花朵，使它们以为日子将永远暖和，因为夏季早填满它们的粘巢。2谁不经常看见你伴着谷仓？

When other technics conditions are certain, we use the globosity aluminum powder of different particle diameter a to grind the flake of aluminum powder , with the particle diameter increase of the globosity aluminum powder, the particle diameter of the flake of aluminum powder will also become bigger immediately. 3, The ratio of grinding ball to aluminum powder is 20:1. 4,the grinding speed is 38 and 33 r.min alternate once h-our in the first 10 hours, and use the speed of 29 and24 per hour alternating revolving speed in the last 5 hours, this speed is fine to grind the flake of aluminum powder. 5, wet method ball-milling mainly adopt of help-milling agent as Bl. 6, influence of the research grinding time.

经系统的研究，得出如下结论：1、基本参数：采用200升球磨机，装入钢球200kg，原料铝粉：溶剂量=1：2，铝粉：钢球=1：20；2、当其它工艺条件一定时，用不同粒径的球状铝粉作为原料磨制片状铝粉，随着原料铝粉的粒径增大，所制得的片状铝粉的粒径也会随之增大。3、球料比我们控制在20：1.4、研磨前10小时采用速38和33r.min每小时交变一次，后5小时用29和24每小时交变的转速，这个速度是适宜磨制片状铝粉的。5、湿法球磨片状铝粉主要采用的助剂为复合助剂B1.6、研究研磨时间的影响。
