[Mononuclear phagocytes in the cerebrospinal fluid. Studies on the clinical significance and factors of activation].
Examination of 1050 cerebrospinal fluid samples showed, that mononuclear phagocytes contribute only slightly to the explanation of affections of the CNS except they are containing specific particles e.g. iron. Further investigations on patients with concussion, herniation of the intervertebral disk and cerebral infarction turned out, that the relative proportion of mononuclear phagocytes and qualitative cytological changes correlate with the extent of the CNS lesion. Phagocytosis of India ink was studied dependent on milieu and different mediators. Phagocytosis correlates with alpha-1-glycoproteid and the relative part of mononuclear phagocytes in cerebrospinal fluid. It depends on pH, various ions and mediators (adrenalin, histamine, prostaglandines, cAMP, cGMP). DNA-contents of the nucleus was measured by cytophotometria. No signs of proliferation (tetraploidia) were found. The slightly increased contents of nuclear DNA of some phagocytes was interpreted as a metabolically active DNA.
