| Outline of Final Research Achievements |
Hericium erinaceum (HE) is a unique mushroom for its cognitive function improving actions (Inanaga et al., 2014). Amyloban 3399 contains Amycenon, a standardized extract of HE, and is currently being tested for safety as a health food supplement. Inanaga reported that PANSS of 10 schizophrenic patients before and after the administration of Amyloban had dramatically improved without side effects. Based on this clinical observations, we challenged to clarify relationship phenomena and metabolites before and after taking Amyloban. We assessed alteration levels of metabolite in a male case who had been treatment-resistant and severe side effects for more than thirty years by using LC-MS/MS techniques in both his urine and plasma samples. We found that several metabolites were remarkably changed before and after administration of this supplements. In the future, we will need to study the effects of specific metabolites on symptoms using a larger number of patients with schizophrenia.
