title: [The repair of injured brain by implanting embryonic cortical brain tissue preserved in Iloprost solution at 4 degrees C: experimental study].
abstract: We transplanted the fresh and Iloprost or saline preserved (3 hours) embryonic rat cortical brain tissue into the rats in which the motor cortex had been injured and compared the neurobehavioral and morphological changes. The neurobehavior of the transplanted groups was more significantly improved than that in the injured, untransplanted group. The neurobehavior of the animals of the fresh tissue group and Iloprost preserved group recovered to the preinjurylevel. The survival rate of the Iloprost preserved grafts was 90%, which was higher than that of the saline preserved grafts (P < 0.05). In comparison with the fresh grafts, however, there was no significant difference (P > 0.05). In addition, the growth volume of the Iloprost preserved grafts was more markedly increased than that of the fresh grafts (P < 0.01). We conclude that injured brain may be repaired effectively by transplantation of fetal brain cortex. The Iloprost solution not only maintains of vitality the grafts, but also promotes its survival and growth in the host brain.
