[Pharmacy students' participation in medicinal education for children].

Over recent years, use of self-medication by patients to help prevent and treat their own medical conditions has become increasingly widespread. However, despite provision of warnings and the taking of precautions, health hazards due to medication have occurred and continue to occur. In order to ward off such incidents, it is necessary for both children and adults to be educated about appropriate drug use. And, it is desirable that pharmacy students participate in this medicinal education as a means of affirming what they have learned and improving their communication skills at an early stage in their professional development. In 2008, we held medicinal education classes for pupils and parents at three elementary schools in Aichi Prefecture with the aim of promoting appropriate drug use. Each class comprised of two parts: an introductory lecture in quiz form, lasting about 30 minutes, and a 30-minute participatory group experiment. Subsequently, the activities carried out in both parts were evaluated across 6 items and 3 items respectively, and scored from Satisfied to Unsatisfied (4-step scale) by the pupils and their parents. We also conducted a questionnaire survey on this activity to the pharmacy students. We achieved successful results, gaining high Satisfied levels (better than 90%) in all items. This activity benefited both the children and the pharmacy students. It not only provided education for the general public regarding the appropriate drug use, but is also helping to foster the development in Japan of well-trained future pharmacists.

Proteomic analysis of lymphoblastoid cell lines from schizophrenic patients.

Although a number of studies have identified several convincing candidate genes or molecules, the pathophysiology of schizophrenia (SCZ) has not been completely elucidated. Therapeutic optimization based on pathophysiology should be performed as early as possible to improve functional outcomes and prognosis; to detect useful biomarkers for SCZ, which reflect pathophysiology and can be utilized for timely diagnosis and effective therapy. To explore biomarkers for SCZ, we employed fluorescence two-dimensional differential gel electrophoresis (2D-DIGE) of lymphoblastoid cell lines (LCLs) (1st sample set: 30 SCZ and 30 CON). Differentially expressed proteins were sequenced by liquid chromatography tandem-mass spectrometry (LC-MS/MS) and identified proteins were confirmed by western blotting (WB) (1st and 2nd sample set: 60 SCZ and 60 CON). Multivariate logistic regression analysis was performed to identify an optimal combination of biomarkers to create a prediction model for SCZ. Twenty protein spots were differentially expressed between SCZ and CON in 2D-DIGE analysis and 22 unique proteins were identified by LC-MS/MS. Differential expression of eight of 22 proteins was confirmed by WB. Among the eight candidate proteins (HSPA4L, MX1, GLRX3, UROD, MAPRE1, TBCB, IGHM, and GART), we successfully constructed logistic regression models comprised of 4- and 6-markers with good discriminative ability between SCZ and CON. In both WB and gene expression analysis of LCL, MX1 showed reproducibly significant associations. Moreover, Mx1 and its related proinflamatory genes (Mx2, Il1b, and Tnf) were also up-regulated in poly I:C-treated mice. Differentially expressed proteins might be associated with molecular pathophysiology of SCZ, including dysregulation of immunological reactions and potentially provide diagnostic and prognostic biomarkers.
