脂肪条带结构富集针刺镇痛效应物质实验观察

目的观察针刺大鼠胃经沿线脂肪条带结构是否具有特异富集针刺镇痛效应物质的作用。方法针刺大鼠单侧"后三里"穴,将针刺侧及未针刺侧胃经沿线脂肪条带结构和脂肪条带结构上皮肤、条带旁肌组织、脑组织、肾上腺提取物以及血清等分别接种于同种异体大鼠,测量受体鼠接种前后痛阈值。结果接种针刺侧胃经沿线脂肪条带结构提取物及血清后,受体鼠出现类似针刺镇痛效应。接种其它部位组织提取物后,受体鼠的痛阈未出现有意义的变化。结论针刺侧大鼠胃络沿线脂肪条带结构具有特异富集针刺镇痛因子的作用。     

动脉正常吻接和张力吻接后顺应性对比研究

通过在体测定狗股动脉正常吻接和张力吻接后不同时相点吻合口段的压力与直接相应的数据,从而得出动脉在正常及张力吻接后的顺应性,以及顺应性与平均血压的关系。结果表明：在各时相点,张力吻接组吻合口段动脉的顺应性均低于正常吻接组,反映出动脉张力吻接合吻合口段的可扩张能力较正常吻接动脉有明显减弱,术后14天减弱最显著,张力吻合对吻合口段动脉的功能有较大影响。

Application of Forearm Ulnar Free Cutaneous or Myocutaneous Flap in Maxillofacial Surgery

Forearm ulnar cutaneous flap is a new type of flap which is safeand convinient, and it can be used for many purposes. It is superior to theradial cutaneous flap in that the wound on the donor site is ratherconcealed, the skin flap is less hairy, and it is easier to be made. The flapis suitable for repairing oral, maxillofacial and neck defects.Myocutaneous or osteomyocutaneous flap can be made on the basis of theskin flap. If the distal end of the flap is used as the pedicle, then anisland flap can be made for the repair of hand defect. The authors usedthis flap to repair 12 cases of oral or maxillofacial defects due to differentcauses. All the cases have been followed for 9-15 months. There wassatisfactory healing of the recipient site both cosmetically and functionallyin all the cases. At the donor site, there was no disturbance of the sensoryor motor functions of the forearm or the hand.     

78例国人奇静脉系及其起源的观察

在78具成人尸体的奇静脉系统中,奇 半 副半型的出现率为64.10％。但半奇静脉系的组成变化很大,这种分型法不易有统一标准。本文根据Seib的观点,以半奇静脉系的中断情况,将奇静脉系分成双干、中间和单干三型,其中以中间型居多(52.56％)。中国人半奇静脉系中断次数和奇静脉与半奇静脉系间的交通支都较白种人多,差异明显,提示了白种人奇静脉系可能接近胚胎型。奇静脉中段常凸向正中线之左,奇静脉系起始处常与下腔静脉或肾静脉连接,这些宜引起临床重视。     

足背皮瓣的静脉

作者前已报导足背皮瓣的动脉。足背皮瓣的静脉,国内已有翁嘉颖等、吴晋宝等、徐恩多等、王学礼等、王永贵等报导,但均系摘要。我们观察了50例足背皮瓣的静脉,材料和方法同前文,只是静脉没有注射颜料或填充剂。     

大鼠岛状皮瓣再血管化的观察

本文采用X线造影和墨汁灌注透明方法,对大鼠岛状皮瓣再植后的血管变化进行了动态观察。结果表明:术后8天,皮瓣和受区之间即可见毛细血管吻台,受区血管长入皮瓣。之后,血管吻接数目逐渐增多,管径增大。皮瓣与受区是否良好贴合是影响再血管化的重要因素之一。皮瓣和受区的血管都经历了一个明显的增生过程。     

大鼠脂肪条带结构针刺镇痛效应特异性的生物学基础

目的:观察大鼠脂肪条带结构针刺镇痛效应特异性的生物学基础。方法:选择大鼠胃经沿线脂肪条带结构上后三里以及脂肪条带结构旁两个对照位点(A1、A2),分别进行针刺,针刺结束后立即断头处死,分离出胃经沿线脂肪条带结构,制备匀浆液,采用放免法测定样本中的β内啡肽(βEP)、强啡肽A(DynA)、P物质(SP)含量。结果:βEP针刺后三里(19.08±7.42)与针刺A1、A2位点(2.27±1.99)经成组t检验比较,两者差异显著(t=5.5374,P<0.01)。DynA针刺后三里(23.08±8.61)与针刺A1、A2位点(2.19±1.81)经成组t检验比较,两者差异显著(t=5.8194,P<0.01);SP针刺后三里(1.57±0.49)与针刺A1、A2位点(1.05±0.60)经成组t检验比较,两者差异不显著(t=1.6330,P>0.05)。结论:针刺正常大鼠后三里腧穴,可使胃经沿线脂肪条带结构上特异性针刺镇痛效应物质βEP、DynA含量升高。
