| Research Abstract |
PK-11195 suppressed the enhancement of glucose metabolism in rat brain induced by infusion of quinolinic acid (QUIN). The enhancement of glucose use induced by QUIN mainly occurred in glial cells, and neuroprotective effect of PK-11195 might be related to the suppression of anaerobic glicolysis in glial cells. Methyl ethyl ketone and diethyl ketone showed significant anticonvulsive and neuroprotective effects in lithium -pilocarpine SE rats, while Ro5-4864 showed only a very weak effect. The binding parameters of PBR in heart, lung and kidney of rats were estimated by employing ^<18>F-FEDAC, which had rapid kinetic properties in these peripheral tissues.
