The authors measured opioid receptor-active components in the CSF of 11 women with postpartum psychosis, 11 healthy lactating women, and 16 healthy women who were not lactating. Activity that eluted with 0.2 M acetic acid 0.7-0.9 times the total volume of the column (fraction II activity) was significantly higher in the CSF of both healthy and psychotic women in the puerperium than in that of the lactating women. Very high levels of fraction II activity were seen in four psychotic patients… CONTINUE READING
