OBJECTIVE: To examine the distribution of rat facial motoneurons contributing different branches under normal situation and when nerve reinnervation occurred following facial nerve axotomy. METHODS: The normal distribution of motoneurons innervated both buccal and marginal mandibular branches and its reorganization after facial nerve reinnervation was observed using retrograde labeling with fluorescein. RESULTS: Under normal situation, the motoneurons contributing buccall and marginal mandibular branches were primarily distributed in the intermedial and lateral subnucleus in facial nucleus and almost completely overlapped. The two types labeled neurons organized closely, but there were no double-labeled neurons. Although the motoneurons contributing buccall and marginal mandibular branches were primarily overlapped 4 month post-anastomosis, the number of the labeled neurons obviously decreased and the organization got more scattered. There were 10% of buccall branches, 5% of marginal mandibular motoneurons in the dorsal subnuleus, 1% of buccall and 4% of marginal mandibular in dorsal ventral and medial subnucleus. The distribution pattern of the motoneurons 6 month post-anastomosis was similar to that of 4 month post-anastomosis, but the number of the labeled neurons increased, and there were 1%-2% double-labeled neurons. CONCLUSION: The distribution pattern of motoneurons innervated both buccal and marginal mandibular branches indicates that it should exist wide-spread communicating branches, and its reorganization after facial nerve reinnervation suggests that misdirected regeneration occurs among motoneurons innervating different branches. 相似文献

OBJECTIVE: To quantify accurately the rate of adverse reactions after the preschool (fifth) dose of adsorbed diphtheria toxoid-pertussis vaccine-tetanus toxoid (DPT) vaccine and to test the hypothesis that large local reactions are attributable to the diphtheria toxoid. DESIGN: Double-blind randomized controlled trial. SETTING: Suburban community public health unit. PARTICIPANTS: Healthy children 4 to 5 years of age with a history of having received four doses of adsorbed DPT vaccine. INTERVENTIONS: Subjects were given either the standard DPT vaccine (with 25 Lf units of diphtheria toxoid) or a modified DPT vaccine (with 10 Lf units of diphtheria toxoid). They were assessed 24 hours later by a nurse. Serum samples obtained before vaccination were tested for diphtheria and tetanus antitoxin levels by means of neutralization assay and enzyme-linked immunosorbent assay. MAIN OUTCOME MEASURES: Rates of large local reactions (an area of redness or swelling or both of 5 cm or greater) 24 hours after vaccination in the two groups. Relation between serum antitoxin levels before vaccination and the rate of large local reactions in each group. RESULTS: Of the 250 subjects enrolled 124 received the standard vaccine and 126 the modified one. Large local reactions occurred in 71% of the subjects receiving the standard vaccine and 52% of those receiving the modified one (p less than 0.01). In the former group large erythematous reactions occurred significantly more often in those with an elevated prevaccination diphtheria antitoxin level than in those without an elevated level; no relation was found between such reactions and the prevaccination tetanus antitoxin level. Reduced arm movement was evident in 45% of the children in the two groups. Few had systemic adverse reactions. CONCLUSIONS: Large local reactions occur frequently after the preschool administration of the DPT vaccine. These reactions are uncomfortable but not serious. They result in part from the large amount of diphtheria toxoid in the standard DPT vaccine. 相似文献

Pleural cryptococcosis is extremely rare. We report the first case of cryptococcal pleural effusion in association with the acquired immune deficiency syndrome. Pleural effusion without the evidence of pulmonary parenchymal involvement was the initial and only clinical finding leading to the diagnosis of disseminated cryptococcosis. The pleural effusion resolved spontaneously prior to amphotericin B therapy. 相似文献

农民工结核病健康教育效果评价 总被引:1,自引:0,他引:1
目的 探讨开展结核病健康教育对提高农民工相关知识知晓率和态度正确率的作用.方法 对重庆市南岸区农民工进行结核病相关知识的健康教育,教育方式是由专科医生进行专题讲座.健康教育讲座前后在同一现场统一发放问卷,并当场收回,对教育前后农民工的结核病相关知识作一一配对比较.结果 调查15项内容,其中有14项内容教育前后有显著性差异.教育前农民工结核病知识知晓率为67.5%,教育后知晓率为99.5%;正向态度报告率从教育前的44.1%提高到60.1%.结论 健康教育能提高农民工防治结核病知识知晓率和态度正确率,此方法值得推广. 相似文献
