目的评价经皮椎体成形术治疗脊柱疾病的临床应用价值.方法 56例多发骨髓瘤、溶骨性脊柱转移瘤、骨质疏松性椎体压缩性骨折患者应用经皮椎体成形术后,分24 h、3个月两阶段评估患者疼痛、术后X线片检查结果、椎体高度等指标.结果术后止痛效果良好,尤以骨质疏松性椎体压缩性骨折患者的止痛效果最好.无严重并发症. 结论经皮椎体成形术对骨质疏松性椎体压缩性骨折等脊柱疾病的止痛、稳固椎体等效果明显,可以谨慎开展.     

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.
