Abstract
Twenty-four cases of mortal brain injuries were studied, the known survival time of which varied from 30 min. to 10 days. There were 2 principal types of injury: depressed fractures and "discontinuous" fractures. The latter were more common in the region of the cribriform plates and orbital roofs. The ventricular system was wounded in three-fourths of the cases. Hematomas were common. It was noted that the cellular reaction of the brain tissue to trauma is more sluggish than the reaction of tissues in other organs. The reactive processes may be designated as traumatic encephalitis. During the 1st to 3d day degenerative processes and edema are accompanied by infiltration with hematogenous mesodermal elements. In the second stage proliferation of capillaries marks the beginning of a reparative process and compound granular corpuscles appear in increasing number.
