[Cell reactions in the cerebrospinal fluid with inflammatory and neuroallergie diseases of the central nervous system (author's transl)].

In the course of bacterial and abacterial meningoencephalitis the cell reaction of the cerebrospinal fluid can well be surveyed, permitting important conclusions to the reactions occurring in the leptomeningeal vascular connective tissue. The application of additional cytological methods in completion of the panoptic routine staining proved to be favourable. The respective results may be additionnally availed of for the diagnostic confirmation of the activities found in the panoptic routine cell-picture. In addition to the general evaluation of the nitro-blue tetrazolium test, pyroninophilia, peroxidase and PAS-reaction, above all, the observation somehow the despositing of the reaction products in the celles has proved to be important for the activity detection of the nonspecific esterase. For judging the immunreactive processes in the central nervous system, the role of the lymphocytes and their forms of transformation, as well as their behaviour with the different cytological reactions has to be duly considered.
