[Changes in blood-filling and cerebrovascular tonus in experimental intracerebral hemorrhage and their correction by means of intravenous infusions of glycerin].

According to the results of rheoencephalography, intracerebral hemorrhage in wakeful cats is attended by an increase in the tone of the cerebral vessels, particularly those of moderate and small caliber, which occurs immediately after blood is introduced into the brain and persists till the end of the follow-up period (48 hours). Intravenous glycerine infusion given one hour and 1-2 days after the hemorrhage causes normalization of the vascular tone. The causes of disparity between the rheoencephalogram indices characterising the tone of the cerebral vessels and their blood filling are discussed.
