赤灵芝的致突变性试验

使用赤灵芝的水提取液、乙醇（３０％）提取液进行鼠伤寒沙门氏菌回复、小鼠骨髓多染红细胞微核和雄小鼠精子畸变等三种致突变试验。剂量为１０００μｇ．皿＾－１和５０００μｇ／皿＾－１的鼠伤寒沙门氏菌回复试验的结果为阴性。小鼠在服用７５００ｍｇ．ｋｇ＾－１的水提取液或２５００ｍｇ．ｋｇ＾－１的醇提取液时，微核试验和精子畸变试验结果均为阴性。     

对我省部分疫区县(市)慢性布病的调查分析

<正> 人的布鲁氏菌病(以下简称布病)是一种以细菌性感染辅以慢性后遗症为特点的传染病,尤其是慢性期布病又是严重危害劳动人民健康、影响农牧业发展的一种常见病。全省75个布病疫区县(市)至今累计发病2万余例,其中有相当一部分病人转入慢性期。为了解现症病人的现状及对劳动生产的影响。我们于1989—1990年对26个布病疫区县(市)进行调查。现将调查结果报告如下: 材料与方法

髂-颈动脉人工血管旁路术治疗Ⅰ型多发性大动脉炎

多发性大动脉炎是一种病因未明的非特异性肉芽肿性病变,其中Ⅰ型累及弓部血管及其上三大分支,导致动脉的完全闭塞或重度狭窄,从而引起严重的缺血症状,故属于该病中症状最重、治疗最困难的一类[1].     

寰枢椎椎弓根钉固定治疗伸直型齿状突骨折合并寰枢关节半脱位

Objective To explore the clinical outcome of atlantoaxial pedicle screw instrument in treatment of extension-type odontoid fracture combined with aflantoaxial subluxation. Methods From December 2002 to December 2006, seven patients with extension-type odontoid fracture combined with at-lantoaxial subluxation were reduced and fixed with atlantoaxial pedicle screw instrument of Vertex system under general anesthesia. There were five males and two females, at mean age of 39.2 years (range 21-59 years). All odontoid fractures were fresh type Aderson Ⅱ. JOA scores of spinal core function was 8.6-14.9 (average 10.7) preoperatively. The X-ray examination, CT scanning and skull traction were performed in all patients preoperatively. Results There found no severe complications such as injuries of vertebral artery, nerve root and spinal cord postoperatively. All patients obtained complete reduction and healing of the fracture and dislocation. The mean off-bed time was four days (3-6 days) after opera-tion. A follow-up for 12-36 months (average 22 months) in all patients showed that the clinical symptom was improved significantly six months postoperatively and that all screws were in proper position verified by X-ray and CT scanning. All patients obtained solid bony union on radiographs, with no loosing or breakage of instrument. The postoperative JOA scores was 13.5-16.9 (average 15.8). Conclusions Allantoaxial pedicle screw fixation has advantages of intraoperative reduction, reliable fixation and high fusion rate and can be used as an effective method for extension-type odontoid fracture combined with at-lantoaxial subluxation.
