肾盂切开气压弹道碎石治疗鹿角形肾结石(附46例报告)

目的 探讨肾盂切开气压弹道碎石治疗鹿角形肾结石的疗效。方法 对46例鹿角形肾结石采用肾盂切开气压弹道碎石，将结石分解成数块，再逐一取出。双侧肾结石采用一次分侧手术取石。结果 46例鹿角形肾结石均较顺利取出，无黏膜撕脱、出血等并发症。25例肾功不全者均显著改善。结论肾盂切开结合气压弹道碎石是治疗鹿角形肾结石较好方法；双侧肾结石多有梗阻致肾功能受损，应双侧一次取石，有利于双肾功能恢复。     

微波凝固联合黏膜下氟尿嘧啶注射治疗早期低位直肠癌

目的探讨微波凝固联合黏膜下氟尿嘧啶（5-Fu）注射治疗早期低位直肠癌的适应证和疗效。方法1996年1月～2002年12月对9例早期低位直肠癌采用微波凝固联合黏膜下5-Fu注射，微波治疗后用含5．Fu1．0g的生理盐水100～200ml保留灌肠，1次／d，连续3d，随访其疗效。结果3例微波治疗前CEA增高，微波治疗后CEA下降至正常。术中、术后无出血等并发症。随访至2006年1月，9例全部存活。l例生存3年5个月；1例生存3年8个月；1例1年4个月后肿瘤复发，行Miles手术至今又生存2年9个月；6例生存5年以上，其中1例5年1个月，1例6年3个月，l例6年8个月，1例7年6个月，2例9年。结论微波凝固联合黏膜下5-Fu注射治疗早期低位直肠癌适应于早期、距肛缘7cm以下、肿块型、肿瘤直径0．5～3．0cm或肿瘤〈直肠周径的1／3、病理类型为高分化肿瘤、且患者强烈要求保肛的直肠癌。该方法具有创伤小、费用低和疗效满意等特点。

本文介绍一种高血压脑出血外科治疗的新方法,即简易定向锥颅脑内血肿碎吸术。截至1988年10月临床应用19例,年龄41～79岁,出血量平均为48.1ml,一次吸除量为总量的79％(38ml),术后立即清醒者8/19例,偏瘫好转者4/19例,死亡4例。实践证明本法简单,安全有效,病人负担轻。     

凯素灵药笔触杀蜚蠊效果观察

凯素灵是新近生产的杀虫剂,对卫生害虫有极强的杀灭作用。以此药配成0.30%、0.25%、0.20%和0.15%四种浓度的石膏药笔,作杀灭美洲大蠊试验,其杀灭率分别为100%、95.0%、60.0%、10.0%。新配制的和放置1、4、7、10个月的0.25%浓度药笔,杀灭率分别为95.0%、90.0%、85.0%、65.0%、40.0%。现场初步观察,对卫生害虫灭效良好。认为0.25%和0.30%浓度石膏药笔,可连续使用4个月以上。药笔具有高效、低毒、价廉、使用方便等优点,可以推广使用。     

Regional effect of estradiol on rat caudate-putamen dopamine receptors: lateral-medial differences

The effect of a chronic 17 beta-estradiol (10 micrograms, b.i.d.) treatment of 2 weeks to ovariectomized rats was investigated on lateral and medial caudate-putamen dopamine receptors. Dopamine D2 receptors were assayed with [3H]spiperone binding to caudate-putamen homogenates or by autoradiography of forebrain sections. Estradiol treatment leads to a significant increase in the density of lateral caudate-putamen dopamine receptors while for the medial dopamine receptors the increase is non-significant. This effect is observed when plasma levels of 17 beta-estradiol and prolactin are increased. These results indicate that the effect of estradiol on striatal dopamine receptors is heterogeneous and that those in the lateral part are more susceptible to this steroid.     

The hepatitis B immunization programme in Singapore

A voluntary immunization programme to prevent perinatal transmission of hepatitis B virus (HBV) infection in Singapore was implemented on 1 October 1985 as an integral component of the national childhood immunization programme. Up to April 1988, a total of 68,845 mothers who attended government maternal and child health clinics were screened for the disease. Of these, 2432 (3.5%) were positive for hepatitis B surface antigen (HBsAg) and 904 (1.3%) for hepatitis B e antigen (HBeAg). Virtually all the babies born to carrier mothers completed the full immunization schedule; and in addition, those of HBeAg-positive mothers were given a dose of hepatitis B immunoglobulin at birth. The hepatitis B immunization programme was extended on 1 September 1987 to cover all newborns. About 90% of the 15,943 babies delivered in government institutions from September 1987 to April 1988 were immunized at birth, with the subsequent doses being administered at maternal and child health clinics at 4-6 weeks and 5 months later. More than 85% of the children given the full course of plasma-derived and yeast-derived hepatitis B vaccine from birth continued to have protective antibody to HBV two years after immunization. The programme is being closely monitored to assess the duration of immunity and the need for booster doses, while seronegative adults are also being encouraged to be vaccinated.
