Pituitary and placentally derived hormones in cerebrospinal fluid during normal human pregnancy.

To examine the potential routes by which placental and pituitary hormones gain access into the cerebrospinal fluid (CSF), normal pregnant women had CSF and blood samples collected after admission to the hospital before delivery. CSF and serum samples, obtained before CSF collection, were examined for PRL, βhCG, and human placental lactogen (hPL). Mean values (±SE) in serum were 5757 ± 815 mlU/ml for βhCG and 22.4 ± 2.42 mlU/ml for CSF, and the serum to CSF ratio was 289 ± 28 in 26 samples in which these parameters were simultaneously measured. Mean serum hPL was 15.3 ± 1.15 fig/ml, and CSF hPL was 0.565 ± 0.048 fig/ml; the serum to CSF ratio from 22 subjects was 22.7 ± 2.32, which was significantly different from the serum to CSF ratios for βhCG and PRL. Serum PRL values were 182.6 ± 17.3 ng/ml, and CSF values were 15.36 ± 1.33 ng/ml; the serum to CSF ratio from 32 subjects was 10.7 ± 1.33, which was lower than the ratio for either)8hCG or hPL. Regression analysis of the simultaneously determined serum an...
