76例宫颈癌组织中人类乳头瘤病毒的检测

本文应用ＨＰＶ－ＰＣＲ技术和ＤＮＡ杂交技术对７６例宫颈鳞癌标本进行了ＨＰＶ－ＤＮＡ的研究，发现ＨＰＶ－ＤＮＡ存在率为９０．７９％（６９／７６），主要类型为ＨＰＶ１６和１８。多酶切ＳｏｕｔｈｅｒｎＢｌｏｔ杂交证实在宫颈癌中９２．５６％的ＨＰＶ－ＤＮＡ发生变异，说明ＨＰＶ－ＤＮＡ的基因变异与其致癌作用密切相关。ＰＣＲ结果证实ＨＰＶ－Ｅ６片段在宫颈癌组织中常可出现，推测可能是致癌的关键片段之一。因此，检测宫颈癌组织中ＨＰＶ－ＤＮＡ的完整性、关键基因片段的存在与否，可能对于病变恶变的预测有一定的意义     

医院感染流行病学监测分析

介绍了我院１９９３年７月１日～１９９３年１２月２０日出院的１０３１例病人医院感染病率的监测分析，半年中感染率为８．４％，妇产科疗区发病率高于外科疗区，感染部位以泌尿道、下呼吸道、手术伤口为最多，侵袭性操作及易感因素引起的感染在感染病例中分别占４０．２％和５９．８％。     

ICR 小白鼠脏器中铜,锌锰含量

对40只正常成年远交系 ICR 小白鼠的主要脏器,用 WFX—Ⅱ型双光束原子吸收分光光度计测定了各脏器中铜、锌、锰含量.结果表明,主要脏器中铜、锌、锰含量大小顺序不一,铜含量最多的脏器是心,锌、锰含量最多的脏器是肝,在雌雄之间均无显著性差异.

Improved Static Compression Behaviors and Tablettabilities of Spherically Agglomerated Crystals Produced by the Spherical Crystallization Technique with a Two-Solvent System

Purpose. Poorly compressible crystals of acebutolol hydrochloride were agglomerated by the spherical crystallization technique with a two-solvent system to improve the compressibility for direct tabletting. The mechanism of improvements in static compression behaviors and tablettabilities of the spherically agglomerated crystals were investigated. Methods. The improvement of static compression behaviors of the agglomerated crystals was determined by measuring the stress relaxations and elastic recoveries of compressed powder of original and agglomerated crystals. The improved tablettability of agglomerated crystals was evaluated by the pressure transmission ratio upon compression, the ejection pressure for releasing the tablet from the die and the tablet strength, i.e., tensile strength required for breaking. Results. The higher relaxation pressure and the lower elastic recovery of the agglomerated crystals than of the original crystals were found. The pressure transmission ratio data showed that the friction pressures of the two crystals were similar during the compression period. The ejection pressure of the agglomerated crystals was lower than that of the original crystals. The tensile strength of the tablet of agglomerated crystals was greater than that of the original crystals. Conclusions. The compressibility and tablettability of the spherically agglomerated crystals prepared by the spherical crystallization technique were much improved due to their increased plastic property and reduced adhesive property compared to the original crystals.     

3，4－二羟基苯乙酮对家兔缺血－再灌心肌的影响

以超微结构、线粒体形态计量及ＬＤＨ，ＳＯＤ活性为依据，探讨３，４－二羟基苯乙酮（ＤＨＡＰ）对家兔缺血－再灌心肌细胞的影响。结果表明：ＤＨＡＰ组缺血－再灌心肌细胞的损伤、ＬＤＨ丢失及ＳＯＤ活性下降的程度均明显低于未用药组。提示该药物对缺血－再灌心肌有保护作用。     

鼻内窥镜诊治脑脊液漏的临床研究

目的 探讨鼻内窥镜手术治疗脑脊液鼻漏临床相关因素。方法 对17例（19漏）内窥镜下修补脑脊液鼻漏患者的临床资料作回顾性分析。结果 脑脊液鼻漏17例中，外伤性15例，自发性2例，内窥镜下瘘口修补术一次性治愈15例，成功率88.2%，失败2例，再次修补成功，其中1例颅内高压术后腰穿持续引流减压。结论 内窥镜手术修补脑脊液鼻漏准确、微创；冠位CT薄层扫描对术前瘘口解剖定位有重要意义；影响手术效果的因素与修补材料的固定有关，与修补材料本身无明显关系；术后适当腰穿引流对于临床提示颅内压高、修补区薄弱病例仍需采用。     

《太医院先生案》考

近来发现一本朝鲜朝宫庭医名录本，暂题名为《太医院先生案》．结合其他文献介绍了宫庭医的情况，并介绍了名录本的文例．这将对朝鲜朝医学史研究有一定的价值     

围手术期肠外营养支持在胃癌根治术的应用

1986～1988年的胃癌扩大根治术221例及根治性全胃切除术19例非肠外营养(N-TPN)支持为对照组,与1991～1993年的198例及61例施行TPN治疗为实验组进行对比。N-TPN组术后并发症总发生率为7.2％,TPN组则为2.0％;全胃切除术并发症发生率分别为31.6％和4.9％(P<0.01)。吻合口瘘发生率N-TPN组分别为2.7％和10.5％,而TPN组则均为0.0％(P<0.01)。膈下脓肿发生率N-TPN组为31.6％和15.8％,而TPN组则为1.5％和3.3％(P<0.05)。但本研究是回顾性的,所以要有待进行前瞻性的、对照的、随机的大范围研究。     

胰岛素样生长因子在人前列腺增生症中作用的探讨

应用免疫组化方法完成了胰岛素样生长因子（ＩＧＦ－Ｉ）在４８例人前列腺增生中的组织定位。组织经４％甲醛固定，石蜡包埋。ＩＧＦ－Ｉ免疫反应主要定位于腺体基底层上皮细胞浆内，阳性染色也见于腺体分泌上皮、鳞状化生上皮、平滑肌细胞和神经纤维细胞内。证实：ＩＧＦ－Ｉ存在于前列腺增生患者的前列腺组织中，并且与前列腺增生的发病有一定关系。
