Scanning electron microscopic findings on the rabbit meninges after local lavage with Polyvinylpyrrolidon-Jod-Komplex.

The microbicide Polyvinylpyrrolidon-Jod-Komplex (P.J.K.) was experimentally evaluated for its use in local lavage of the epidural space. In 20 rabbits a lumbar laminectomy was performed followed either by local lavage with P.J.K. or with NaCl. After one month the meningeal covering of the operated spinal cords revealed no signs of fibrosis or arachnoid adhesions when studied macroscopically or by scanning electron microscopy (SEM).
