〔追加討論〕〔1〕PATHOLOGY OF JAPANESE ENCEPHALITIS—Problem of viral multiplication within cells

　It is impossible to understand the pathology of viral encephalites without regards to the virus multiplying in cells of nervous system. For instance neuronophagia of viral encephalitis should be understand as reaction of microglias or histiocytes not merely to dead nerve cell but to the virus multiplying within nerve cell. From above point of view I would like to add a supplemental explanation to my previous paper. (Matsuyama；Keio Journal of Medicine 4, 11, 1955,).
