[Influence of protein content on total CSF protein (author's transl)]

The influence of the protein content of nutrition on the total protein of the cerebrospinal fluid was examined in 24 neurological patients showing neither inflammatory diseases nor diseases where a rise of the total protein in the CSF can be expected. 14 patients were at random separated into two groups and received either a high protein or a low protein isocaloric diet for seven days. The then observed changes in the total protein content of the CSF between both groups were significant. In ten other patients whose total protein content of the first lumbal puncture was beneath 35 or above 55 mg% the observed changes after high protein or low protein diet were more pronounced, the farther a value was situated from the normal range. It is asked if the "normal range" has not to be defined depending on the protein uptake with nutrition.
