流行性出血热患者骨髓细胞超微结构的研究

8例流行性出血热患者骨髓细胞的超微结构研究结果发现骨髓细胞出现变性、空泡、粗面内质网及高尔基体扩张。并在胞浆中发现颗粒-丝状病毒包涵体及直径为100nm的病毒颗粒。同时胶体金免疫电镜发现骨髓细胞EHF抗原阳性,说明骨髓细胞是其繁殖、复制的场所。     

An animal model of chronic tympanic membrane perforation.

Previous investigations into the healing and reconstruction of tympanic membrane (TM) perforations have involved animal models with acute TM perforations. A problem with the acute TM perforation model is that most acute TM perforations will heal spontaneously, both in animals and human beings. A second inadequacy of acute perforation models is that they are not analogous to the salient problem in human beings: long-standing TM perforation. The ideal animal model must have a TM perforation that is permanent, well-epithelialized, and free from infection. The perforation must also be subtotal to preserve a rim of membrane for experimental manipulations. In the chinchilla, we have identified a hardy animal with a short, wide ear canal and relatively large tympanic membranes. Thermal myringectomy, followed by medial infolding of TM microflaps, has resulted in permanent, subtotal chronic TM perforations in the chinchilla animal model. Of the 19 chinchillas (38 TMs) perforated, chronic subtotal perforations were created in 32 ears, 6 to 8 weeks after the initial procedure (84% success). Persistent infection or TM regeneration despite reperforation was recorded in 6 ears (16%) failure). This model is currently being used to assess various biomembrane scaffolds impregnated with growth-promoting substances in the regeneration of a physiologically sound TM, initially in our animal model and then in human beings. We envision the development of a biomembrane disc impregnated with biorecombinant growth factors that may provide a simple office technique for the repair of chronic, non-infected TM perforations.     

Antimicrobial susceptibility of respiratory Haemophilus influenzae strains isolated from pediatric respiratory tract infections

BACKGROUND: Haemophilus influenzae (H. influenzae) is the most frequent bacterial pathogen of respiratory tract infections in children. Detection of antimicrobial susceptibility of H. influenzae is necessary for institution of appropriate antibiotic treatments. METHODS: A total of 281 strains of H. influenzae isolated from sputum samples of 281 pediatric patients with respiratory tract infections were recruited for study. Antibiotic susceptibility was determined by assessing minimum inhibitory concentrations (MIC) of antimicrobial agents. MIC were measured by utility of Agar dilution susceptibility test. RESULTS: Of the total, 38 (13.5%) strains produced beta-lactamase (BLP), 56 (19.9%) strains were beta-lactamase non-producing, ampicillin resistant (BLNAR). The overall resistant proportion to ampicillin was 33.4%. The data indicated that sulbactam/ampicillin, cefotaxime, ceftriaxone and cefditoren are effective against BLP strains. In addition, a high prevalence of BLNAR H. influenzae strains was identified, with an overall isolation rate of 19.9%. Those strains mainly demonstrated intermediate level to ampicillin (ampicillin-MIC 相似文献   

辐照氟银猪皮的实验研究

报道辐照氟银猪皮的制备、实验检测（弹性、创面粘附力和透水性测定，含银量测定）组织学检查细菌检测及抑菌试验研究，结果表明：辐照氟银猪皮除延伸度低于未辐照猪皮外，其撕裂强度、创面粘合力和透水性均与未辐照猪皮相似。组织学检查示：辐照氟银猪皮组织结构完整，表皮细胞部分空泡形成。组织细菌检测证明其无菌生长，达到无菌要求。抑菌试验证明对金黄色葡萄球菌、绿脓杆菌、大肠杆菌、变形杆菌、克雷伯氏菌均有极强的抑菌作用     

开颅术后张力性气颅

报告１９８８年１２月～１９９２年１２月开颅术后张力性气颅５例，男４，女１．５例中３例治愈，２例死亡。开颅术后张力性气颅产生的主要原因是颅内占位性病变切除后，脑脊液丢失，使颅内压降低，甚至呈负压状态，外界的气体从切口进入颅内的腔隙，ＣＴ扫描或颅骨Ｘ线平片可以确定诊断，钻孔置管排气是活疗张力性气颅的有效方法，作者探讨了预防此种并发症发生的措施。     

溶栓颗粒治疗急性缺血性中风68例临床研究

目的：观察溶栓颗粒治疗急性缺血性中风的疗效。方法：将128例急性缺血性中风患者随机分成3组，在一般内科治疗基础上分别口服溶栓颗粒（治疗组）、溶栓胶囊（对照组1）、尼莫地平（对照组2），治疗3周，观察临床疗效。结果：治疗组临床疗效优于对照组1、对照组2（P〈0．05），3组治疗后与治疗前比较症状均有明显改善（P〈0．05），治疗组证候疗效优于对照组1、对照组2（P〈0．05）。结论：溶栓颗粒是治疗急性缺血性中风的有效药物。
