Interposed autologous nerve segment stimulates nerve regeneration in peripheral nerve allografts in a rat model.
The ability of autologous nerve segments interposed between allografts, to increase the total nerve-gap distance, was studied. Sciatic nerve allografts were carried out in a rat model. A 15-mm nerve gap was repaired with a 25-mm nerve graft (interposed group: allo-auto-allograft; control group: allo-allo-allograft). Cyclosporin was given for 12 weeks. Nerve regeneration was evaluated using the weight of the anterior tibial muscle and histologic, morphometric and immunohistochemical analyses at 12, 13, 14, 15, 16, 20, and 24 weeks. Nerve regeneration in the interposed group was statistically significantly better than that in the control group. The authors concluded that a nerve allograft with interposed autograft may enhance nerve regeneration in this model, because of the migration of host-derived Schwann cells into the graft from not only the proximal and distal host nerve stumps, but also the interposed autograft.

[Laboratory medicine in the field of emergency medicine and disaster medicine--Old-And-New tools of emergency medical service].
We reviewed the characteristics of the field of laboratory medicine concerning emergency medicine and disaster medicine. Gram's stain was apt to be made light of by clinicians, but it has been reviewed again. A modern sophisticated analysis system is expected for the consequence management of NBC terrorism and mass poisoning, but we would like to emphasize the importance of the basic physical strength of laboratory medicine, such as Gram's stain, to the meaning of old-and-new technology.
