Neuroprotector effect of comenic acid against cytotoxic action of glutamate in vitro in cultured neurons of lead-poisoned rat pups.

We demonstrated an increase in glutamate neurocytotoxicity in cultured cerebellar cells from rat pups subjected to lead poisoning during the prenatal development or early lactation period. The toxic effect of glutamate was weaker, if lead was applied in combination with antioxidant comenic acid. These data are discussed in view of practical use of comenic acid for the therapy of the brain tissues subjected to lead poisoning.

Stimulatory effect of green tea extract on the growth of neurites in the rat spinal ganglion culture.

Addition of green tea extract in concentrations of 0.004-0.006% to the nutrient medium markedly stimulated the growth of spinal ganglion neurites of 1-2-day-old rats.
