The frequency of X-chromatin was determined in pregnant women during the second trimester of gestation in order to establish possible correlations with the changes in steroid hormone levels occurring during this period and compare the curve with that for normal nonpregnant women. The mean frequency of X-chromatin in oral mucosa cells from a salivary suspension was 19.97% for the 24 patients studied, a statistically higher value than that obtained for nonpregnant women.
为了确定妊娠中期孕妇X染色质的频率与该时期类固醇激素水平变化之间可能存在的相关性，并将该曲线与正常未怀孕女性的曲线进行比较，对妊娠中期孕妇进行了研究。在所研究的24名患者中，唾液悬液中口腔黏膜细胞的X染色质平均频率为19.97%，该值在统计学上高于未怀孕女性。
