绒毛膜性疾痫的研究己进入运用染色体遗传因子,来说明萄萄胎管生机制的阶段。从美国最近的资料来看,葡萄胎发生率的地区差、比以前所认为的低1.5—2.5倍左右。葡萄胎染色体的大部分由46XX 构成。1977年 kajil 使用染色体分染法,探索了20例葡萄胎的染色体,提出了葡萄胎染色体来自父亲。yamashita 证明根据 HLA(人体淋巴细胞抗原系统)PGM(糖分解体系酶)等酶的多型分析葡萄胎也来源于父亲。Surti 提示占全葡萄胎4%的46×γ是由父亲二个精子受精所致。ohama 报告部分性葡萄胎的染色体分析,3倍染色体占80—90%,证明
Chorionic eclampsia research has entered the use of chromosomal genetic factors to illustrate the stage of the mechanism of grape fetus birth. According to recent data from the United States, the regional difference in the incidence of hydatidiform mole is about 1.5-2.5 times lower than previously thought. The majority of hydatidiform chromosomes are composed of 46XX. In 1977, Kajil used chromosome-based staining to explore the chromosomes of 20 cases of hydatidiform mole and proposed that the hydatidiform mole came from his father. Yamashita proved that hydatidiform mole also originated from father according to the multi-type analysis of enzyme such as HLA (Human Lymphocyte Antigen System) PGM (Sugar Decomposition System Enzyme). Surti suggests that 4% of the total hydatidiform mole 46 × γ is due to the fertilization of two sperm mothers. Ohama reports chromosomal analysis of partial hydatidiform mole with 80-90% triple chromosomes, proving
