Experimental Study of Healing of Trans-Sected Peripheral NervesSummary. The behavior of the connective tissue during the healing of transsected nerves was studied. Experiments were carried out with rabbits. The sciatic nerve was trans-seeted and repaired using different techniques. Postoperatively the animals were all treated in exactly the same way. The clinical course was registrated carefully, with special attention to the return of the motor function and the occurence and extension of decubital ulcers. Finally the animals were sacrified, and the site of nerve repair was excised and histologically examined using H~matoxilin, Eosin. Van Gieson, Kresylviolett, Kliiver-Barriera, Sudan-Schwarz B, Bodian staining.Two different techniques were compared by operating on the two sciatique nerves of the same animal. Individual factors could be excluded as the result of each two operations was compared in the same individual.A. In 32 rabbits, 64 sciatic nerves were repaired by epineural end-to-end suture (Mersilen 6 • 0) in order to study the timing of the healing process.
