对12例引产死胎的脾脏测定,结果表明36周胎脾的滤泡基本形成,已具有一定的细胞免疫功能。38周胎脾的IgA(388mg/dl)、IgM(34mg/dl)及IgD(118.1U/ml)已接近成人血清中含量,具有相当的体液免疫功能。38周胎脾的体积已能达到移植的要求。为此用作胎脾移植的胎龄应以38周以上为宜
12 cases of induced labor stillbirth spleen determination results showed that 36 weeks of fetal spleen basic formation of follicles, already has a certain cellular immune function. IgA (388 mg / dl), IgM (34 mg / dl), and IgD (118.1 U / ml) in 38 weeks of gestation were close to those in adult serum and had comparable humoral immunity. The volume of 38 weeks of fetal spleen has been able to meet the transplant requirements. For this purpose for gestational age of fetal spleen transplantation should be more than 38 weeks is appropriate
