有些学者以大鼠为实验对象进行椎板切除后硬膜外瘢痕形成与粘连的实验研究[1～ 3] 。由于低级动物椎板有再生能力 ,且速度较快 ,这无疑会影响预防效果观察的准确性。作者对大鼠是否适合作椎板切除后防止硬膜粘连的实验模型作了观察。材料与方法 成年ＳＤ大鼠 2 4只 ,体重 2 0
Some scholars in rats as the experimental object after laminectomy epidural scar formation and adhesion of experimental study [1-3]. Because of the regenerative ability of the lower animal lamina, and faster, it will undoubtedly affect the accuracy of preventive effect observation. The authors observed whether the rat is suitable for laminectomy to prevent the adhesion of the dura after the experimental model was observed. MATERIALS AND METHODS: 24 adult SD rats weighing 20
