46例男性性腺发育不良患者的临床表现和染色体分析

Turner's syndrome is the most frequently occurring type of gonadal dysgenesis. Its main manifestations are primary amenorrhea, short stature, streak gonads, sexual infantilism, webbed neck, cubitus valgus, specific facial features and various somatic anomalies.

Turner综合征的典型临床表现有原发闭经、身材矮小、条索状性腺、性幼稚、蹼颈、肘外翻、特殊面容祀其他身体异常。

Objective To discuss the correlation between sex chromosomal abnormalities and gonadal dysgenesis.

目的探讨性染色体异常对性腺发育的影响.

using gonadal dysgenesis ( gd) as the standard method of assays, the p element activity and cytotypes of 14 strains collected from eastern part of coastal areas in china have been measured, which are situated from 20 ° north latitude to 40 ° north latitude.

采用性腺败育（GD不育）作为标准检定方法，对我国东部沿海14个地方的（北纬20°~40°）黑腹果蝇的P因子活性和细胞型进行了测定。

Analysis of SRY gen in 6 cases of gonadal dysgenesis patients
