The effect of MS-818, a pyrimidine compound,on the regeneration of peripheral nerve fibers of mice after a crush injury

One of the pyrimidine compounds, 2-piperadino-6-methyl-5-oxo-5,6-dihydro(7H)pyrrolo[3,4-d]pyrimidine (MS-818), has neurotropic effects in vitro. Therefore, we studied the effect of MS-818 on the regeneration of the peroneal nerve in C57BL/6J mice after a crush injury. Two test groups, which received a daily intraperitoneal injection of 5 mg/kg or 10 mg/kg MS-818, respectively, were compared with controls, which received daily intraperitoneal injections of physiological saline, over a 14-day period. The maximum foot-width ratio (crushed side/uncrushed side) was obtained on days 1, 8 and 14 after the crush injury, and the various morphometric parameters were evaluated at both 5 and 10 mm distal to the proximal portion of the crush site. The significant effects of MS-818 included a larger maximum foot width (P<0.04) and a greater number of unmyelinated axons per nerve at both levels (P<0.003) in both test groups than in controls. MS-818 had no significant effects on body weight, the increase of total transverse fascicular area after the crush injury, the total number of myelinated fibers with their size distributions, or the number of nuclei of Schwann cells and macrophages. Therefore, we conclude that MS-818 promotes axonal sprouting and elongation after a crush injury in mice.     

颞叶癫痫手术时的皮质脑电描记

提要报告1980年10月至1992年6月间,在皮质脑电描记下手术治疗颞叶癫痫55例,前颞叶切除50例,杏仁核、海马切除5例。皮质脑电描记结果说明,颞叶癫痫的痫灶绝大多数来源于颞叶外侧皮质和颞叶内侧结构。术中皮质脑电描记可提供痫灶的精确部位和范围。     

地塞米松促胎儿肺成熟的三种用药方式对母体糖代谢的影响

【目的】探讨地塞米松的用药方式对孕妇糖代谢的影响。【方法】对 1999年 9月至 2 0 0 1年 1月在本院住院的15 0名不同用药方式使用地塞米松促胎儿肺成熟的孕妇进行研究 ,在用药前及用药后 18～ 2 4h抽取肘前静脉血查空腹血糖、血浆C肽 ,糖负荷后 2h血糖、血浆C肽。【结果】使用地塞米松后 ,空腹血糖值、糖负荷后 2h血糖值、空腹C肽及糖负荷后 2hC肽值较用药前高 ;用药方式对母体空腹血糖值和空腹C肽值的影响差异无统计学意义 (P >0 0 5 ) ,对母体糖负荷后 2h血糖值和糖负荷后 2hC肽值的影响差异有统计学意义 (P <0 0 5 ) ;不同糖代谢状态的受试者使用地塞米松后 ,空腹C肽值、糖负荷后 2hC肽值的改变差异有统计学意义 (P <0 0 5 )。【结论】孕妇使用地塞米松促胎儿肺成熟对母体的糖代谢均有一定程度的影响 ,用药过程中和用药后需严密监测母体血糖和胎儿宫内状况     

Efficacy of phototherapy in non-haemolytic hyperbilirubinaemia

Clinical experience of phototherapy for non-haemolytic hyperbilirubinaemia in 3999 infants in Kandang Kerbau Hospital, Singapore, is documented. Phototherapy was most effective in extremely preterm infants with very low birth weight (gestation less than or equal to 32 weeks, birth weight less than or equal to 1500 g) and least effective in full term infants with very low birth weight (gestation greater than or equal to 37 weeks, birth weight less than or equal to 1500 g) and large preterm infants (gestation less than 37 weeks, birth weight greater than 2270 g). Overall, phototherapy was effective in almost all the infants, with a failure rate of only 2.00/1000 infants. No characteristic features common to all the failures could be detected. The bilirubin rebound was usually mild; repeat phototherapy was required in only 30 infants (7.50/1000), with the response to the second exposure comparable to that to the first. No infant required a third exposure. All the infants tolerated phototherapy well, none developing any illness that could be attributed to the treatment. This clinical experience shows that phototherapy for the treatment of nonhaemolytic hyperbilirubinaemia is effective and safe.     

前列腺素E1和一氧化氮联合治疗室间隔缺损并肺动脉高压的疗效观察

目的 :观察静脉应用前列腺素E1(PGE1)、吸入一氧化氮 (NO)及二者小剂量联合应用对室间隔缺损 (VSD)并肺动脉高压的治疗作用。方法 :将 2 4例VSD并肺动脉高压的病人随机分为 3组 ,观察静脉注射PGE16 0ng/ (kg·min)、吸入NO 2 0ppm及静脉注射PGE130ng/ (kg·min)联合吸入NO 10 ppm对病人的血流动力学及血氧饱合度的影响。结果 :静脉注射PGE16 0ng/ (kg·min)使肺动脉平均压 (MPAP)明显下降 ,体动脉平均压 (MSAP)亦有所下降 ,心指数 (CI)明显增加。吸入NO 2 0 ppm组MPAP明显下降而MSAP无明显变化 ,CI有所升高 ,但差别不显著。静脉注射PGE130ng/ (kg·min)同时吸入NO 10 ppm组MPAP明显下降 ,但不显著 ,CI明显升高。 3组血氧饱合度均明显升高。结论 :联合应用小剂量PGE1和NO不仅能有效降低MPAP ,又能适当轻度降低MSAP ,改善心功能 ,减轻了NO的毒副作用 ,是一种较理想的治疗方案
