Measurement of prostaglandin F2alpha levels in human cerebrospinal fluid in normal and pathological conditions.

Prostaglandin F2alpha concentrations were measured in human cerebrospinal fluid by the gas-chromatography-mass spectrometric technique using 2-H4-PGF2 alpha as internal standard and carrier. Normal levels of 71.6 plus or minus 34.7 pg/ml were found. Considerable increases in PGF2 alpha concentrations were found in patients with epilepsy, meningtitis or following cerebrovascular accidents or neurosurgical removals of brain tissue. The results agree in general with recent measurements using radioimmunoassay.
