[The research of the pathogen responsible for Pleurocybella porrigens related encephalopathy: investigation of 3-nitropropionic acid hypothesis].

Pleurocybella porrigens related encephalopathy exhibits consciousness disturbance and convulsion in the patients after taking and patients show bilateral basal ganglia lesion resulted in high mortality rate. This encephalopathy is a very similar to the moldy sugarcane encephalopathy epidemic in China in the past. We investigated the relationship between Pleurocybella porrigens related encephalopathy and 3-nitropropionic acid which had caused the moldy sugarcane encephalopathy. We have tried to detect 3-NPA in the various specimens from patients and Pleurocybella porrigens, but failed. Further examinations for elucidating the causation of Pleurocybella porrigens related encephalopathy are needed.
