The plasma concentrations of estrogen (estrone, estradiol and estriol) were measured in 34 OPLL cases, aged 37-74yr and 30 non-OPLL cases, aged 37-74yr, using radioimmunoassav mpthnd.
The mean concentrations of estrone in OPLL cases and non-OPLL cases were 65.1pg/ml and 72.6pg/ml. The mean concentrations of estradiol in OPLL cases and non-OPLL cases were 27.0pg/ml and 22.4pg/ml. The concentrations of estrone and estradiol were not significantly different between OPLL cases and non-OPLL cases. The concentration of total estrogen was significantly higher in OPLL cases and non-OPLL cases than in healthy younger men.
The high plasma concentration of estrogen in OPLL cases was due to aging.
