自体表皮细胞培养与异体真皮组合应用研究

严重烧伤病人皮肤修复中主要未解决的问题是真皮的替代。动物实验结果表明，异体皮移植后５天，用自体培养表皮细胞膜片覆盖真皮床，１４天后复合皮成活率是８４．６％±２．４％。组织学检查证实表皮已形成了复层结构，可见基底层、颗粒层和角质层。临床应用中，异体皮移植后１０天，去除异体表皮覆盖病人的自体培养表皮，３５天后未见排斥征象，异体真皮促进了培养表皮的分层、成熟和完整，组织学检查证实表皮细胞的边缘清楚，已分化形成颗粒层和角质层，真皮多细胞，已血管化，但表皮嵴缺乏。     

Effect of hepatitis C antibody screening in blood donors on post-transfusion hepatitis in Taiwan

A national screening programme for antibody to hepatitis C virus (HCV) in blood donors in Taiwan began in July 1992 using a second-generation immunoassay. To study the impact of this screening on post-transfusion hepatitis in Taiwan, a prospective study on post-transfusion hepatitis, that was started in 1987, was continued. As of June 1994, 245 patients who received a blood transfusion after July 1992 had completed a follow-up period for more than 6 months post-transfusion. Of them, seven (2.8%) recipients developed acute post-transfusion hepatitis. The hepatitis in six cases could not be attributed to infection by hepatitis A, B, C, D, E viruses or cytomegalovirus (CMV) or Epstein-Barr virus (EBV). The remaining patient seroconverted to both IgG and IgM anti-CMV. All seven patients recovered in 6 months without development of chronicity, and the mean peak alanine aminotransferase level was lower compared with that of the cases before anti-HCV screening (i.e. pre-July 1992). These results indicate that the current anti-HCV screening has effectively interrupted HCV transmission through blood transfusion in Taiwan.     

The bioavailability and nonlinear pharmacokinetics of MK-679 in humans

MK-679 (R(?)-3-((3-(2-(7-chloro-2-quinolinyl)ethenyl)phenyl)(3-(dimethylamino)-3-oxopropyl)thio)methyl)thio(propanoic acid) is a potent and specific LTD₄-receptor antagonist. The disposition of MK-679 was investigated in a three-way crossover study in 12 healthy males receiving single intravenous doses of 75, 250, and 500 mg of MK-679. A greater than proportional increase in the area under the plasma concentration—time curve of MK-679 was observed with increase in dose. The plasma concentration data for each subject fitted well to the differential equations for a two-compartment model with linear tissue distribution and Michaelis-Menten elimination from the central compartment, indicating that the elimination of MK-679 in humans is saturable. In a previous study, the disposition of MK-679 in humans was also dose-dependent when given together with its S(+)-isomer, L-668,018. Thus, the disposition of MK-679 in humans is dose-dependent regardless of the presence of its stereoisomer. Also, the bioavailability of MK-679 was determined in six healthy males receiving simultaneously an oral dose of 250 mg of MK-679 and intravenous infusion of 1 mg ¹⁴C-MK-679. Results of this study indicate that the oral bioavailability of MK-679 is nearly quantitative.

Carotid-cavernous sinus fistula associated with a primitive trigeminal artery

Carotid-cavernous sinus fistulas are not rare, but they have never been reported in association with persistent primitive trigeminal artery. We recently encountered such a case. The Jaeger-Hamby procedure was employed, with mandatory occlusion of the primitive trigeminal artery.     

脊髓手术中体感诱发电位监测的临床研究

报告３０例脊髓手术中体感诱发电位（ＳＥＰ）连续监测的临床研究结果。ＳＥＰ记录包括脊髓ＳＥＰ（ＳＳＥＰ）和皮层ＳＥＰ（ＳＣＥＰ）。麻醉药物对ＳＥＰ有一定程度影响，ＳＣＥＰ相对较大。认为，至少术中ＳＥＰ潜伏期延长不超过８％和波幅降低不超过５０％，不会引起术后并发症，超过该范围由于病例较少，尚不能肯定与预后的关系，需进一步探讨。     

重组人红细胞生成素治疗肾性贫血的临床分析

目的　观察重组人红细胞生成素 (RhEPO)对肾性贫血的治疗作用。方法　根据使用EPO剂量的不同将 39例慢性肾衰竭并血液透析病人分成 4组 ,观察治疗后 2、4、12个月时与治疗前 (0月 )相比红细胞数 (RBC)、红细胞比积 (Hct)及血红蛋白含量 (Hb)的变化。结果　 2 4例使用EPO10 0 - 15 0IU/ (kg·w) (6 0 0 0IU/w - 90 0 0IU/w) ,治疗后RBC、Hct、Hb较治疗前有显著升高 (P≤ 0 .0 0 1) ;5例使用EPO5 0IU/ (kg·w) (30 0 0IU/w) +间断输血患者 ,其RBC、Hct、Hb升高不显著 ;10例不用EPO而单纯输血患者 ,其RBC、Hct、Hb无明显变化 (P >0 .0 5 )。结论　EPO能较好地纠正肾性贫血 ;单纯输血不能治疗肾性贫血

子宫内膜增生性病变与子宫内膜癌的超声诊断价值

目的:探讨子宫内膜增生性病变与子宫内膜癌的超声鉴别诊断及内膜癌肌浸程度的估价.方法:采用术前B超、术后大体标本观察测量,对123例子宫内膜病变患者的声像图资料进行分析并与手术后病理结果对照.结果:①子宫内膜病变者子宫三径之和平均值均大于正常值;②58.6%的子宫内膜增生过长病变患者内膜形态以条形、梭形和正常形态回声;35%的Ⅱ期以上子宫内膜癌患者内膜回声以积液为主兼有其它图像类型;③大于50岁患者不同病理类型病变的子宫内膜平均厚度均超过其正常内膜厚度值,但无明显的规律性.小于50岁的患者内膜增厚主要以子宫内膜增生过长病变为主占48%;④通过超声测量子宫内膜厚度判断子宫内膜癌浅肌层和深肌层浸润符合率均为71.4%.结论:超声检查对判断子宫内膜病变病理类型有一定帮助,内膜厚度、内膜形态、回声特点、及内膜与肌层间的关系等,仅提示病变存在的可能性,要鉴别病变的良恶性、肌层浸润深度,须根据上述回声特点进行综合分析.
