Increased incidence of retching and vomiting during periovulatory phase after middle ear surgery

Purpose  

To assess the effect of the menstrual cycle on post-operative retching and vomiting (R& V) after middle ear surgery, and the efficacy of prophylaxis against R& V in female patients with transdermal scopolamine during either general or local anaesthesia and with intravenous ondansetron during general anaesthesia.     

Experimental brain tumors by transplacental ENU

Summary Experimental cerebral tumors have been induced by transplacental ENU. The morphologic study of the brains of treated rats revealed that cellular hyperplasias appear at the 30th day of extrauterine life in the paraventricular white matter, i.e., before the already known early neoplastic proliferations. Cytofluorimetric investigations failed to demonstrate differences between treated and control rats during the 1st month. On the contrary, adenylate cyclase activity is very high in that period. The duration of the latency period is discussed.This research was supported by Grants No. 79.00678.96 and No. 79.00664.96 of Progetto Finalizzato Control of Neoplastic Growth, Consiglio Nazionale delle Ricerche (C.N.R.), Rome     

Pediatric surgery in the Renaissance period

The emergence of surgery during the Renaissance marked the birth of surgery as a discipline based on clinical observation and improvement of technical skill. Some of the most experienced surgeons dealing with pediatric problems were Paré, Phaer, Würtz and, especially, Hildanus, who described more than 150 cases in children. Some minor malformations were curable, and some major anomalies were described for the first time. Renaissance surgeons had no explanations for the etiology of diseases and malformations. In many instances, the imaginatio was considered to be responsible.     

糖尿病对大鼠坐骨神经动作电位潜伏期影响的观察

目的：观察糖尿病对大鼠坐骨神经动作电位潜伏期的影响。方法：剥离大鼠坐骨神经,利用BL-310生物信号处理系统测量其动作电住的潜伏期。结果：糖尿病大鼠坐骨神经动作电位潜伏期约为0．92ms，比正常大鼠动作电位潜伏期延长。

目的　观察头孢吡肟治疗骨科围术期医院获得性肺炎的疗效及安全性 ,并与头孢他啶进行比较。方法　骨科围术期医院获得性肺炎 70例随机分为两组 :头孢吡肟组 3 5例 ,静滴 1.0～ 2 .0g ,2次 /d ;头孢他啶组 3 5例 ,静滴 1.0～ 2 .0g ,2次 /d ;两组均治疗 1～ 2周。结果　头孢吡肟组及头孢他啶组临床有效率分别为 94.2 9%及 91.43 % (P >0 .0 5 ) ,细菌清除率分别为 94.12 %及 90 .91% (P >0 .0 5 ) ,不良反应发生率均为 2 .86% (P >0 .0 5 )。结论　头孢吡肟治疗骨科围术期医院获得性肺炎的疗效显著而又安全     

辨证分期治疗慢性盆腔炎合并免疫性不孕症18例疗效观察

目的：探讨辨证分期治疗慢性盆腔炎合并免疫性不孕症的临床疗效。方法：选择慢性盆腔炎合并免疫性不孕症(血清抗精子抗体阳性)患者18例，采用辨证分期治疗。月经干净后，治以活血化瘀、理气祛湿为主；在(或相当于)排卵期或排卵后，治以补肾养血，活血化瘀为主；在经前期，治以理气活血调经为主；在月经干净后至经前期，加用小剂量阿司匹林。结果：盆腔炎临床症状及体征痊愈7例，显效6例，有效5例；全部患者获得妊娠，宫内妊娠者17例(观察至妊娠3月，均正常)，输卵管妊娠1例；结论：中医辨病辨证结合的周期疗法加小剂量阿司匹林治疗慢性盆腔灸合并免疫性不孕症有一定的疗效。     

高血压病史对体外循环冠脉搭桥术后早期预后的影响

目的 :了解高血压病史对体外循环下冠脉搭桥术后早期预后的影响。方法 :对高血压和非高血压行体外循环下冠脉搭桥术年龄大于60岁的冠心病患者65例术前和术后早期的临床资料进行分析。结果 :与非高血压患者相比 ,患高血压的病人冠脉搭桥术后心律失常的发生率增高 ,术后30min动脉氧分压与吸入氧浓度 (PaO2/FiO2)比值明显低下 ,机械通气时间明显延长 ,术后24h内胸腔引流量明显增加 ,术后大剂量多巴胺 (>10μg·kg-1·min -1)应用率及重症监护时间无显著性差异。结论 :高血压病史使患者冠脉搭桥术后早期肺功能下降、心律失常发生率增高、出血倾向增加 ,提示维持高血压患者围手术期血压的正常有利于改善患者预后     

CO2激光治疗350例重度宫颈糜烂疗效观察

目的探讨CO2激光治疗重度宫颈糜烂的方法、疗效和注意事项。方法采用CO2激光输出功率0～50W,波长10.6微米,光束强度适中,光斑直径为0.5cm的连续波,治疗重度宫颈糜烂350例。结果术后4个月复查,所有病人都有效,总有效率100%。结论CO2激光治疗术简单安全,疗效满意。主要适用于Ⅰ～Ⅲ度宫颈糜烂患者,重度更适用此方法。早期发现早期治疗是成功的关键。
