Comparative studies were made on circulating antigen (CAg) detection,routine examination and biochemical analysis of cerebrospinal fluid (CSF) in 408 cases with neurocys-ticercosis. The results showed that the occurrence rates of eosinophile in CSF of both CAg markedly increased group (50.43%) and weakly increased group (41.26%) were higher than that of the negative group (17. 65%). The biochemical analysis of CSF in 274 cases with neurocysticercosis demonstrated that the level of chloride was normal, and t...
