Treatment with 3-(2-carboxypiperazin-4-yl)-propyl-1-phosphonic acid (CPP),
a potent and competitive N-methyl-D-aspartate antagonist, is able to reduce
the hypoxia-induced increase in striatal dopamine level by 26% even after
the hypoxic insult has occurred. The hypoxia-induced decrease of the striat
al 3,4-dihydroxyphenylacetic acid level can also be reversed by CPP. This s
tudy demonstrates that CPP can antagonize the hypoxia-induced changes in th
e dopamine metabolism in the striatum of the newborn rat. (C) 1999 Publishe
