[Possible error in interpretation of liquor enzyme activities as demonstrated on the example of lactate dehydrogenase and cholinesterase].
If examinations of the liquor are to give an insight into the metabolic condition of the brain, then it is necessary for all sources of error to be removed. The use fo exact methods requires that the liquor be free of major pleocytosis. In vitro examinations showed that additions of blood caused the activity of LDH to be doubled within thirty minutes, while that of cholinesterase even increased sixfold. It is especially after craniocerebral injuries that extra care must be taken to insure that the liquor used is as clear as water.
