摘    要:本项研究证实从4~6.5个月的胎儿组织提取的有效成份(简称HFE)具有多种生物学活性:可促进受照射损伤的小鼠造血功能的恢复,4项检测指标包括:①骨髓有核细胞数:实验组:65.5±15.8,对照组:16.4±6.2。②外周血网织红细胞百分比X±SD,实验组:16.6±0.60,对照组0.2±0.04。③CFU-SX±SD,实验组:19.6±9.66,对照组:1.9±2.28。④骨髓增生程度:实验组优于对照组。对5个肿瘤细胞株和正常人二倍体细胞株2BS均有不同程度的抑制生长作用,ED50分别为Hela:62.5μg/ml,MCF-7:7.8μg/ml,HEP-2:4μg/ml,SMMC7721:62.5μg/ml,Tea:4.5μg/ml,而对LA-795和A-549则有轻度刺激作用。可刺激人外周血单个核细胞增殖并与PHA,IL-2有协同作用。对氨甲喋呤引起的大鼠肝、肺损伤有一定的保护治疗作用。本项研究将为其临床应用提供实验依据。

关 键 词:HFE-人胚胎提取液,CFU-S-脾集落形成单位,MTT比色法,细胞存活率,细胞增长率

Abstract:This study confirmed that the human fetal extract(HFE) of 4-6.5months old embryo tissue had various biological activities:(1)promoted the recovery of damaged hemopoietic system in mice caused by X ray as evidenced by a)number of bone marrow nucleated cells,b)peripheral reticulocyte count,c)CFU-S,d) proliferation of bone marrow in femur;(2) inhibited growth of several tumor cells;(3)enhanced peripheral blood lymphocyte(PBL)proliferation synergistically with PHA or/and rIL-2,(4)promoted regeneration of the damaged tissue caused by methotrexate.
Keywords:Human fetal extract MTT Effect
