Tetraploidy of human chromosome(92, XXYY) has been described very rarely. Liveborn infant with tetraploidy was reported in only 17 cases(complete 7 cases, mosaicism 10 cases) in the world, and no cases have been reported in Korea. The diploid-tetraploid mosaicism could arise during the early mitosis of the zygote : In one blastomeric cell, the chromosomes replicate but the cytoplasm does... |

Purpose : Perinatal asphyxia is an important cause of neurologic morbidity. Experiments in animal models of hypoxic-ischemic brain injury demonstrate that brain damage starts during hypoxia-ischemia. In order to evaluate the ischemic condition-induced neurotoxic effect in view of oxi- dative stress, we examined the cytotoxic effect in cultured cerebral neurons of neonatal mouse.
Methods : Dissociated cell cultures were prepared... |
