Measurement of prostaglandin E2 in cerebrospinal fluid in patients suffering from stroke.

In 16 patients suffering from cerebrovascular events, prostaglandin (PG) E2 was measured in their cerebrospinal fluid and correlated with their clinical status and evolution. Prostaglandin E2 ranged from 200-3000 pg (picogram)/ml of cerebrospinal fluid. A positive correlation was found between PG E2 levels and the severity and clinical outcome of the stroke.
