Abstract: The offspring of rats with experimental hyperhomocysteinemia caused by alimentary loading with dietary methionine within
pregnancy has been studied. Using pinealon (Glu-Asp-Arg) under these conditions was found to result in the offspring cognitive
function being improved significantly and their cerebellum neurons becoming more resistant to oxidative stress. This may be proved by
the fact that the administration of pinealon to pregnant rats loaded with methionine improved their offspring spatial orientation and
learning ability and decreased both reactive oxygen species accumulation and the number of necrotic cells in the population of the
neurons isolated from the cerebellum of the offspring developed under the prenatal hyperhomocysteinemia. Our experiments allowed
confirming the neuroprotective properties of pinealon, which is in agreement with the previous data obtained by us in vitro.
