Background: Omeprazole is mainly metabolized in the liver by CYP2C19, a genetically determined enzyme, whereas rabeprazole reduced non‐enzymatically and partially CYP2C19. The therapeutic effects of are therefore assumed to be less affected an individual’s CYP2C19 status. Aim: To investigate acid inhibitory plasma levels omeprazole with reference different genotypes. Methods: Fifteen healthy volunteers took daily dose 20 mg or for 8 days. On post‐dose days 1 8, 24‐h profiles intragastric pH...

Background: Self-disturbances in schizophrenia have begun to be explained by an abnormality the sense of agency (SoA). The cerebral structures SoA healthy people are considered mainly include insula and inferior parietal lobule. In contrast, functional lesion aberrant is not yet fully understood. Considering recent explanation establishing from standpoint associative learning, "agency network" may only lobule but also striatum. We hypothesized that based on a deficit network". Methods:...

Abstract Clinicopathological issues regarding so‐called ‘alcoholic dementia’ remain under debate. Although clinical observation favors the diagnosis of primary alcohol dementia, caused by direct neurotoxicity, further confirmation from neuropathological and biochemical perspectives is warranted. Repeat episodes subclinical Wernicke–Korsakoff’s syndrome may partially account for chronic state alcoholic thus supporting notion that dementia exists in continuum with types syndrome. Diagnostic...

A family history of alcoholism has been demonstrated to be an important factor affecting cognitive function. However, no studies have yet conducted compare recovery history-positive (FH+) and history-negative (FH-) alcoholics in the subacute withdrawal period. To tackle this problem, a neuropsychological test battery consisting six computerized tests was administered 19 FH+ 20 FH- at 2 7 weeks after abstinence. At abstinence, overall performance both groups significantly poorer than that...
