取５０只大白兔分为５组，每组１０只，分别用０．９％氯化钠、Ｍｙｏｄｉｌ（碘苯酯）、Ｉｏｐａｍｉｒｏ（碘异肽醇）、Ｏｍｎｉｐａｑｕｅ（碘苯六醇）、Ｉｓｏｖｉｓｔ（碘帕醇）作脊髓造影。每组于造影后１天、３天、１周、４周、７周各取２只，静脉气栓处死后，取腰、颈段脊髓作光、电镜观察。作者观察到Ｍｙｏｄｉｌ易引起粘连性蛛网膜炎；Ｉｏｐａｍｉｒｏ导致蛛网膜反应性增生远大于Ｏｍｎｉｐａｑｕｅ和Ｉｓｏｖｉｓｔ。 Fifty rabbits were divided into five groups with 10 rats in each group, which were treated with 0.9% sodium chloride, Myodil, Iopamiro, Omnipaque, Isovist Iopamidol) for myelography. Two rabbits in each group were sacrificed at 1 day, 3 days, 1 week, 4 weeks and 7 weeks after angiography. The spinal cord of the lumbar and the cervical spinal cord was taken for light and electron microscopy after the death of venous air embolism. The authors observed that Myodil predisposes to adhesive arachnoiditis; Iopamiro results in a much greater arachnoid reactive hyperplasia than Omnipaque and Isovist.
