Studies on the properties of some peripheral MAO inhibitors

1. Studies were carried out on three monoamine oxidase (MAO) inhibitors, two of which, debrisoquine and para- hydroxyphenelzine, are purported to be peripheral inhibitors and one, phenelzine, is a peripherally acting inhibitor, which has been included for comparitive purposes. 2. All three showed varying degrees of specificity towards MAO type A. 3. The action of debrisoquine was very rapid as was that of para- hydroxyphenelzine. 4. The inhibition caused by debrisoquine was competitive and reversible, while that caused by both phenelzine and para- hydroxyphenelzine was irreversible. 5. The inhibition caused by debrisoquine appeared to be unaffected by the pH of the medium.     

萘普生对大鼠着床期宫内PGF_(2α)含量及宫内节育器抗生育作用的影响

本文测定了对照组及两个萘普生(前列腺素合成酶抑制剂)处理组大鼠着床期宫内PGF2α的含量。结果表明,对照组、萘普生低剂量组(2mg/kg体重)和高剂量组(20mg/kg体重)的PGF2α含量分别为6.71±0.93、2.19±0.34和1.01±0.18ng/100g组织(三组间P<0.01)。同时,还观察到在本实验条件下,萘普生无明显干扰节育器抗生育作用,药物本身亦未呈现显著抗生育活性。     

多希紫杉醇联合顺铂治疗晚期非小细胞肺癌疗效观察

目的观察和评价多希紫杉醇联合顺铂(DP方案)治疗晚期非小细胞肺癌的疗效和毒性。方法将我科近几年收治的48例晚期非小细胞肺癌患者随机分为治疗组和对照组。治疗组采用多希紫杉醇联合顺铂(DP方案),对照组采用长春瑞滨联合顺铂(NP方案)。2周期化疗后进行疗效、毒性对比研究。结果治疗组和对照组近期有效率分别为45.5%和37.5%,疾病进展时间(TTP)分别为6.3和5.9个月,中位生存期分别为10.1和9.0个月,1年生存率分别为45.8%和39.4%,两组间比较差异均无显著性(P>0.05)。治疗组在恶心呕吐、骨髓抑制等毒性反应发生率方面低于对照组,差异有显著性(P<0.05)。结论多希紫杉醇联合顺铂治疗晚期非小细胞肺癌与NP方案相比较,疗效相似,但毒性反应低于NP组,患者更易耐受,可广泛应用于临床。     

南通市居民健康知识水平现状及对策

为全面了解和准确掌握南通市各行各业、中小学校健康知识的知晓情况,对创建国家卫生城市健康教育工作进行效果评估。调查显示,南通市11个片区健康知识的总知晓率居民为93.42%,学生为91.08%。要真正提高全体市民的健康教育水平,下一步必须采取三大对策,即:形成“抓反复、反复抓”的常态机制;加大健康教育投入;教育部门加强全市学生的健康知识普及工作,对卫生部门列入学校卫生的指标加以考核。只有这样,南通市的健康教育工作才能跃上新台阶。
