The concentration of alpha-1-antitrypsin in cerebrospinal fluid and serum in a series of 40 intracranial tumors.
Forty patients with histologically proved intracranial tumors were submitted to preoperative lumbar and venous punctures. The concentration of alpha-1-antitrypsin in the serum and in cerebrospinal fluid was determined by radial immunodiffusion technique. In the series, both serum and cerebrospinal fluid alpha-1-antitrypsin concentrations are significantly higher than the mean normal values. No statistical differences are observed in serum alpha-1-antitrypsin levels between benign and malignant tumors, but cerebrospinal fluid alpha-1-antitrypsin is significantly increased in the group of malignant tumors if cases undergoing steroid treatment are excluded. The diagnostic value of alpha-1-antitrypsin determinations in groups of patients with intracranial tumors is suggested.

Cerebrospinal fluid and serum immunoglobulins and C3 in Creutzfeldt-Jakob disease.
We determined the concentrations of IgA, IgG, and C3 in spinal fluid and IgA, IgG, IgM, and C3 in serum from seven patients with histologically revified Creutzfeldt-Jakob disease. The mean total protein content in spinal fluid was significantly higher than in controls. The increased mean concentrations of IgA, IgG, and C3 in spinal fluid, and their respective mean percentages in spinal fluid, suggest a passage of IgG and C3 from blood into spinal fluid, and a possible production of IgA within the central nervous system.
