【摘要】 为研究脑组织修复与3H－TdR（氚标胸腺嘧啶核苷）掺入之间的关系，本实验采用昆明小鼠20只，制成脑损伤模型，分别于术后3天、1周、2周、3周取损伤部位的脑组织，进行3H－TdR放射活度测定。5只作对照。结果：术后3天和1周3H－TdR液闪计数最高，分别为45．92±20．02和41．11±22．34，对照组为15．76±96。两组间有明显差异（P＜0．01；P＜0．05）．说明伤后3天至1周脑组织摄取3H－TdR最多。更多还原

【Abstract】 For study the relations between renovation of brain tissue and 3H－TdR（3H－thymidine）incorporation， 20 Kunming mice were made into model of traumaite brain injury by surgery，and other 5 Kumming mice served as control．Brain tissue at injury region was excavated, and 3H-TdR was assayed on the third day,the first,second and third week after surgery， re-spectively.Results:The activith of 3H－TdR on the third day and 7th day was the highest as 45．92±20．02u and 41．11±22．34u respectively， and 15．76±96．00u in the control group．There was singnificant difference between them（P＜0．of， P＜0．05）． It indicates that the intake of 3H－TdR in injuried brain tissue was maximum from the 3rd to 7th day after surgery.更多还原
