冬季住院病入口温与腋温值的对比观察

临床测体温时,经常遇到患者正在进食或饮开水等不宜测口腔温度的情况,而改测腋下温度.为保持体温单的整洁统一,往往把腋温换算成口温.我们于1998～2000年的冬季对我院住院病人进行了口温与腋温的对比观察.现报告如下.

流行性腮腺炎并发脊髓炎１例报告吴玉琴郑秀凤（附属医院２７１０００）流行性腮腺炎常并发睾丸炎、胰腺炎、脑膜脑炎、心肌炎等，而并发脊髓炎者仅占０．２～０．８％。笔者遇到１例报告如下：患者，男，１４岁，学生。因发热、两腮腺肿大６天，于１９９４年４月２０日急...     

528例食管（贲门）癌手术吻合器重建术后吻合口的观察

我们自1986年12月至1994年初应用沪产GF-I型吻合器等系列器械重建食管胃吻合口588例,其中术后528例进行了吻合口及生活质量随诊观察,现报告如下。 临床资料 本组病例,男374例,女154例,年龄34岁～72岁,平均59.3岁。食管胸上段6例,胸中段168例,胸下段74例,贲门癌280例。食管胃吻合方法:颈部吻合8例,弓上吻合240例,弓下吻合280例。吻合口并发症:吻合口瘘4例占0.76％,吻合口狭窄2例占0.38％,吻合口出血占0.19％。随诊方法: 1.食管造影随诊,从术后1个月开始,每3～6个月来复诊时作随诊造影观察,随诊率达89.79％。按复诊时间顺序排队各位患者的食管片,随机抽取其中1份三位片进行评价。经统计学处理吻合口直径在11mm～26mm者占到85％,而且与术后的时间无直接关系。测定吻合口直径最小5mm,最大35mm,平均20mm。     

小型猪致龋模型的实验探讨

动物实验是目前医学研究中的重要手段,是临床应用前必不可少的最有实用价值的基础实验。猪在解剖组织学、生理学方面与人有极大的相似性、猪的牙体形态结构、体积等方面与人牙的相似。因此将猪作为口腔病研究的实验动物越来越受到重视。     

兔动静脉短路环法诱导组织工程骨支架材料血管生成的初步研究

Objective To compare the effects of 2 vascular carriers, arteriovenous loop and arteri-ovenous bundle, on inducing angiogenesis in coral scaffold of vascularized tissue-engineered bone in animal models.Methods Thirty-six adult male New Zealand rabbits were randomized into 2 even groups.In group A, an arteriovenous loop (AVL) was formed by microsurgical anastomosis at the proximal ends between the femoral poptiteal artery and vein, and placed in the circular side groove of the coral block (6 mm × 8 mm × 10 mm) .In group B, flow-through vessels bundles of both femoral artery and vein were placed in the side grooves of the coral block.All the implants in 2 groups were wrapped by a micro-porous expand-ed-polytetrafluoroethylene (ePTFE) membrane, and fixed subcutaneously by suturing.Evaluation methods included gross morphological observations, histological examinations, India ink perfusion and vascular casting after 2, 4, 6 weeks.The density of blood vessels was analyzed by the statistical software SPSS 10.0.Results All the corals were encased by newly formed fibrovascular tissues in 2 groups.Ink-stained vessels distributed the surfaces and side grooves, and invaded the interspaces of corals.The degree of vascularization increased over the course of experiment.Blood vessel density demonstrated a significant continuous increase between 2 and 6 weeks after implantation in group A.The mean value of blood vessel density in group A (2 weeks 276.60±4.67, 4 weeks 517.20±10.66, 6 weeks 707.00 ±11.87) was significantly higher than in group B (2 weeks 153.60 ±7.16, 4 weeks 269.40±6.80, 6 weeks 279.20±6.53) (P <0.01).Vascular casting showed that in group A, significant blood vessels sprouted from all areas of the loop, espe-cially at the entrance of the arteriovenous pediele where the small tubes were densely interconnected.In group B, however, no blood vessels sprouted from the arteriovenous bundles and only some small vessels grew from the entrance and exit.Conclusions A vascularized coral model can be constructed by inserting an ar-teriovenous loop or an arteriovenous bundle, useful in vascular bone tissue engineering.The former, however, have stronger abilities to induce angiogenesis than the latter.
