Alkaline phosphatase level in CSF in various brain tumors and pulmonary carcinomatous meningitis
The authors have examined the activities of the enzymes GOT, CPT, CK, LDH, gamma-GT, PCHE and ALP in the cerebrospinal fluid of 50 patients with various neurological diseases. The results obtained show that many activities constantly and remarkably increase in few diseases of the nervous system. Particularly, GOT, GPT, LDH and ALP demonstrated raised values in the meningitis; LDH, CK, GOT, GPT in the brain tumors; CK and LDH in the hydrocephalus. A comparison between the results of the protein and enzyme determinations in the cerebrospinal fluid of the same patients, revealed in the enzymologic reactions a more precocious and sensitive indicator of initial brain lesions.
