The progressive changes of the brain tissue around the experimental intracerebral hematoma and the oilwax which were made stereotaxically at the lateral portion of the internal capsula of the dog were observed histologically.<BR>Half hour after making the hematoma, spongy change of the brain tissue was found around the hematoma. Six hours after, three layers of the changes were observed. The inner layer was the necrotic layer in which red blood cells infiltrated, the middle was the layer with perivascular bleeding and the outer was the layer with spongy changes. Each change was increased progressively.<BR>These histological changes of the brain tissue around the hematoma were stronger than those of the oilwax.<BR>The spongy change which might be caused by the mass pressure was influenced easily by the hematoma components. So it seems that the layer of the necrosis and the perivascular bleeding on the hematoma case are stronger than those of the oil-wax case.<BR>According to above mentioned data, it is concluded that the hypertensive intracerebral hematoma, if it is possible to remove, should be evacuated as early as possible after the onset for its good prognosis.
