２０只同种成年纯白兔，分别用新鲜和培养孕龄１０～１３ｄ的胎兔脑组织、组织培养物，钻孔脑皮质内移植，每处移植脑组织０．３～０．５ｇ，移植物可以在体内存活、生长、增殖。在动物实验的基础上，对６例不同原因引起的大脑发育不全病人采用４个月水囊引产的胎儿脑组织行多点钻孔，多面脑皮质内移植，每例移植胎脑组织８～１２ｇ。结果：５例症状当天即有改善；随访１．５～２ａ，３例癫痫停止发作；４例肌张力明显降低，肢体功能显著改善；智商提高３８～５１分，脑电图慢波减少，癫痫波消失，ＢＡＥＰ、ＶＥＰ、ＳＥＰ、ＭＥＰ不同程度改善；１例临床症状稍有改善，有效率８３％。结果提示：胎脑组织移植治疗大脑发育不全是有效的。
Twenty adult pure white rabbits of the same kind were respectively implanted with fresh and cultured fetal brain tissue of 10 ~ 13 days old and tissue culture, and were implanted into the cerebral cortex. Each brain tissue was transplanted 0.3 ~ 0.5g, Material can survive in the body, growth, proliferation. On the basis of animal experiments, 6 cases of brain hypoplasia caused by different causes were treated by multi-point drilling and multifaceted cortical transplantation of fetal brain tissue with 4-month abortion. . Results: The symptoms of 5 cases improved on the same day; 3 cases of epilepsy were stopped after 1.5-5 months of follow-up; 4 cases of muscle tension were significantly reduced and limb function improved significantly; IQ increased 38-51 points, EEG slow wave reduced, epilepsy Wave disappeared, BAEP, VEP, SEP, MEP improved to varying degrees; 1 case of clinical symptoms improved slightly, the effective rate was 83%. The results suggest that: Fetal brain transplantation for brain hypoplasia is effective.
