Concerning the small methodical range of error and the little expenditure of work microzone electrophoresis of the non-concentrated CSF after staining with nigrosine and after evaluation on non-transparent acetate film should have priority to microzone electrophoresis of concentrated CSF. This paper reports a comparison of microzone electrophoresis of non-concentrated and concentrated CSF.

The two-dimensional immunoelectrophoresis on cellulose acetate, already utilized for serum proteins, has been applied to CSF proteins. The technical modifications which allow the use of unconcentrated CSF are described. By utilizing a particularly suitable supporting medium, a good separation of proteins is achieved; consequently narrow-based peaks are obtained and the isoantigens can be displayed as distinct components in spite of closely similar migration velocities. The preliminary results of this method are given. Particulary interesting appears a beta-migrating protein and the gamma-migrating oligoclonal bands. The first may present an anodic cleavage suggesting that it may be the beta1C/beta1A-globulin. If this hypothesis is confirmed, the relative concentrations of the two components can be investigated. No clear-cut peaks corresponding to the gamma-migrating oligoclonal bands have been observed, their place being taken by a low precipitation line continuous with the IgG peak. The reasons for this phenomenon may be tentatively ascribed to a local specificity of these IgG.

Results of microzone electrophoresis of non-concentrated CSF after staining with nigrosine and after evaluation on non-transparent acetate film are compared with those of isotope cisternography (111In-DTPA). We found that blood-CSF barrier disturbances begin with an increase of the absolute values of prealbumins in normal CSF circulation. When a barrier impairment occurs, by first increasing the absolute values of alpha1-globulins, we state a pathological CSF circulation. In this case, most of the globulin region is pathologic (globulin-type).

Isotachophoresis in polyacrylamide gel tubes (PAG-ITP) and in capillary tubes (Tachophor, LKB) have previously been found by the authors, to be very promising high-separation methods for CSF and serum proteins, especially regarding the diagnosis of MS. PAG-ITP methods for analytical and preparative use have been described by the authors elsewhere, while in this paper proper cationic systems for ITP in capillary tubes for studying gammaglobulins in microliter amounts of CSF and serum are described, i.e. the albumin injection-clog problem is avoided and the preparation time can be forced. By using microdialysis of the CSF samples for desalting, with a technique easy to perform and with high reproducibility, microliter amounts of native CSF can be performed in less than half an hour. The method seems to be even more applicable for clinical and scientific use if the capillary isotachophoretic apparatus is connected to a synchronized equipment (LKB Tachophrac) with a cellulosa acetate strip onto which the separated fractions are ejected for further analysis by immunological tests. The analytical systems used have been especially directed to gammaglobulins in CSF and serum regarding further studies on demyelinating and infectious disorders of the nervous system.

As reported previously, mouse peritoneal macrophages could be activated to kill intracellular trypomastigotes of Trypanosoma cruzi, the agent of Chagas' disease, in either of two ways: by immunizing and boosting the mice (3), or by culturing resident or inflammatory macrophages in spleen cell factor(s) (SCF) in vitro (2). Macrophages activated in vivo became less trypanocidal with time in culture, and cells activated in vitro lost trypanocidal capacity when CSF was removed (2). In the present study, the ability of macrophages to release H2O2 in response to phorbol myristate acetate (PMA) could be induced in vivo and in vitro, and reversed in vitro, in a manner correlating closely with changes in trypanocidal activity. Macrophages could be activated in vitro with SCF in a time-dependent and dose-dependent fashion, so that they released as much H2O2 as macrophages activated in vivo. The sensitivity of epimastigotes and trypomastigotes to enzymatically generated H2O2 suggested that the generation of H2O2 by activated macrophages could be plausible explanation for their trypanocidal activity. Of the biochemical correlates of macrophage activation reported to date, increased ability to release H2O2 seems most closely allied to enhanced capacity to kill an intracellular pathogen.

Apart from the use of anamnestic data the most common techniques for the diagnosis of CSF leakage have included X-ray studies, and chemical analysis of glucose, protein, and electrolytes of the fluid obtained from the nose or ear, intrathecal staining, and radioactive cisternography. These studies, although useful, have not always succeeded in demonstrating the CSF leakage, especially when the leak is delayed, small, or contaminated. A new immunochemical technique for the identification of the CSF leakage is described. It is based on demonstration of an extra band of transferrin located in the beta 2-fraction of protein electrophoresis of CSF. This beta 2-transferrin is pathognomonic for liquor and could not be demonstrated in serum, nasal secretions, saliva, tears, or peri- and endolymph. After routine protein electrophoresis on cellulose acetate membranes, the transferrins are identified by application of anti-transferrin on beta-regions. Stained precipitates in both beta-regions demonstrate clearly the presence of CSF. Compared with other methods, the new technique offers many advantages. The amount of sample needed for the procedure is small, moderate contamination does not invalidate it, it makes it possible to localize the leak by differential suction, and it is absolutely safe for the patient.

A CSF electrophoresis on a particular gelatinized cellulose acetate (Cellogel RS) has been tested. The method allows the routine separation of many protein fractions in concentrated CSF in a very brief time and affords the recognition and quantification of oligoclonal banding, that is of extreme importance in the diagnosis of some neuropathies as multiple sclerosis.

A patient developed symptomatic lymphocytic meningitis with hypoglycorrhachia after two intrathecal injections of methylprednisolone acetate. Chills, fever, and confusion occurred ten days after the second injection, and were brief in duration. There were no obvious sequelae. Hypoglycorrhachia secondary to intrathecal steroids has not been previously reported. Steroid-induced chemical meningitis should be considered in any patient who develops CNS symptoms and an abnormal CSF after receiving intrathecal steroids. Obviously, the more common causes of lymphocytic meningitis with or without hypoglycorrhachia must be excluded.

In order to select the most discriminative laboratory method of MS diagnosis, the results obtained with CSF IgG/total protein ratio, CSF-IgG Index, agarose and cellulose acetate electrophoresis were compared. The electrophoretic methods appear to be more discriminative for MS than IgG/total protein ratio or the CSF-IgG Index. Furthermore, cellulose acetate electrophoresis was found to be simpler and quicker to perform than agarose electrophoresis.

The time course of ventilatory adaptation to medroxyprogesterone acetate (MPA) and potential mediators of this response in plasma and lumbar CSF were determined in five healthy adult males. A significant decrease in arterial PCO2 (PACO2) at rest and exercise was noted within 48 h of drug administration with the maximum effect reached within 7 days and amounting to a 5-Torr decrement in PACO2. Blood and lumbar cerebrospinal fluid pH because significantly alkaline to control as soon as the ventilatory resporse was noted and remained alkaline during the treatment period. The ventilatory and dP/dt max response to exogenous CO2 was unchanged but their response to moderate exercise was increased after MPA. MPA-rlated materials were detected in both the plasma and CSF as soon as the ventilatory response was noted. The increase in CSF MPA-related materials approximated the unbound fraction determined in plasma. We conclude that [H+] in plasma and CSF is a function rather than a cause of ventilator acclimatization to MPA. MPA-related materials are capable of crossing the blood-brain barrier and could potentially exert their ventilatory stimulant effect by some central mechanism.
