[The effect of glycerol on local cerebral blood flow in patients with chronic ischemic cerebrovascular lesions].
The effect of glycerol on local cerebral blood flow was examined in patients with chronic ischemic cerebrovascular diseases (CVD). Twelve patients with minor completed stroke (10 cases) or transient ischemic attacks (2 cases) were subjected to the study (8 males, 4 females, the age ranging 27 to 70 with average of 56 +/- 15 years). Cerebral blood flow (CBF) was measured with stable xenon computerized tomography (Xe-CT). Each patient had 3 sequential Xe-CTs; resting, with intravenous administration of 200 ml of glycerol (group A) or lactated Ringer's solution (group B), and with intravenous administration of 1 g of acetazolamide. The resting CBF, CBF with glycerol, and CBF with acetazolamide were 30.4 +/- 1.6 ml/100 g/min (ml), 35.1 +/- 2.6 ml, 44.2 +/- 2.2 ml in group A, and 29.9 +/- 2.0 ml, 28.5 +/- 1.9 ml, 45.0 +/- 3.2 ml in group B, respectively. Glycerol increased CBF significantly in patients with chronic CVD, and seemed to be effective in ameliorating chronic low perfusion state in these patients.
