We tested the neuroprotective effect of a novel, high affinity serotonin (5
-HT1A) agonist, BAY X3702, in a rat model of acute subdural hematoma (ASDH)
. Animals were treated with 0.01 mg/kg (n = 8), 0.003 mg/kg (il = 8) BAY X3
702 or vehicle (n = 4) 15 min before (i.v.) and after (continuous infusion)
injection of 400 mu l of autologous blood into the subdural space. The isc
hemic brain damage at 4 h after ASDH was 59.01 +/- 39 and 60.8 +/- 49 mm(3)
for the low- and high-dose BAY X3702 group, respectively, which was signif
icantly smaller compared to the vehicle-treated ASDH group (106.2 +/- 33 mm
(3)). The result indicates that this novel, high affinity 5-HT1A agonist, B
AY X3702, is neuroprotective in this model. (C) 1999 Elsevier Science B.V.
