Hypoxia induces an elevation of excitotoxic amino acid concentrations and may influence hypoxic-in- duced basal ganglia injury. During pregnancy, hypoxia as the destructive factor of CNS alters concentration and mental retardation during childhood. The NMDA antagonist, MK-801, is known to block the effect of amino acids and protect the developing brain against hypoxic insults. To test the hypothesis that MK-801 change prenatal hypoxia affects on the optical density of the μ-opioid receptor system in the developing brain, we quantified optical density of the μ-opioid receptors in several areas of newborn rat brain. In the analysed cerebral structures of rats' brains short-lasting hypoxia leads to the decrease in optical density of n-opioid receptors. MK-801 lessens optical density of μ-opioid receptors in CPu, NA and LMPoA structures.

This experiment was carried out on male Wistar rats aged 6, 12, and 24 months in two seasons, autumn and winter. In all age groups, the activity of Mg-dependent ATP-ase (Mg2+ -ATPase) showed rhythmic oscillations with a 12-hour period. A similar time course was observed for 12-hour variations in Mg and Ca concentrations. In both seasons the maxima of ATP-ase Mg activity paralleled the maxima of Mg and Ca concentrations. When two maxima were observed, one of them always occurred in the light phase and the other in the dark phase of the 24-hour LDcycle.
