Abstract
IN the previous communication1 from this laboratory it was noted that progesterone in concentrations of more than 10 µg (and up to 50 µg tested) per mg wet weight human non-pregnant myometrial tissue inhibits the human myometrial ATPase activity on an average of 27.3 per cent (P < 0.001) based on fifteen experiments. On the other hand, oestradiol in fourteen cases in similar concentrations as for progesterone showed only an average reduction of 5.8 per cent (P < 0.01) on ATPase activity2.
