Adenylate Kinase Activity in Cerebrospinal Fluid in Connection with Transitory Ischaemic Attacks

Abstract

Adenylate kinase activity was measured in cerebrospinal fluid of healthy normal individuals and those having suffered from transitory ischaemic attacks (TIA). Normally, no adenylate kinase was present in cerebrospinal fluid. A slight but distinct activity was always registered in the 11 cases studied in connection with TIA. Cerebrospinal fluid of 2 patients was also analysed in a symptom-free interval (at least 2 weeks after the stroke) and no adenylate kinase activity was found.
