Requirements for education on proper use of drugs were included in the junior high school educational guideline in 2012 incorporating pharmaceutical education in the obligatory school curriculum. This move is closely related to the country's new OTC drug marketing system. The amendment of the Pharmaceutical Affairs Law (PAL) in 2013 highlighted the public's own role in “promoting proper use of drugs and other related products and making greater efforts to acquire knowledge and improve understanding of their effective and safe use”. Furthermore, the Law to Amend the PAL and Pharmacists Law enforced in 2014 allowed all OTC drugs to be sold online under appropriate rules. Deregulation of online sale of OTC drugs is expected further to promote self-medication for minor illnesses and require stricter measures to ensure people's safety through their proper use. These legal amendments in recent years have made people's education about proper use of drugs one of the top priorities Japan should pursue at state level. Since 2000, the author has been offering education on drugs to early primary school children as part of their healthcare education program. In the future, dedicated education on drugs will be necessary for people of all ages including not only school children but also their guardians and elderly citizens as well.

For prevention of the aggravation of diabetic nephropathy, a treatment method that combines self-care with medical guidance is becoming increasingly important, leading to the development of programs for lifestyle modification for the patients. To assess the effectiveness of such programs, we have conducted a feasibility study of a patient self-care support program with medical collaboration by registered pharmacists in community pharmacies involving patients with diabetic nephropathy who are under treatment at medical institutions, including our hospital. This study evaluated the two primary measurements, which are A) the actual execution rate versus planned programs, and B) the patient satisfaction rate. In addition, the achievement rate of behavioral objectives, satisfaction rate of diabetes treatment, degree of concerns (Diabetes Treatment Satisfaction Questionnaire; DTSQ, Problem Areas in Diabetes; PAID) and other physiological indicators have been evaluated. With the approval of the IRB at Kitasato University, sixteen out of 18 patients have continued to participate in the support program, and the study has shown high patient satisfaction with pharmacist coaching support. Patients have gained interest in managing their lifestyles, thereby increasing self-efficacy. Also, information shared between the pharmacists and the physicians has clarified patients' issues and concerns pertaining to their lifestyles, which were effectively utilized in the coaching program. Through meetings with pharmacists, patients have been reassured of the expertise of the pharmacist and thus gained mutual trust, which leads to the patient's behavioral change. We believe that the collaboration of patients, pharmacists and physicians has resulted in effective team-based patient care.

To promote the education on medicines in school, guidance is, as a rule, to be given in the health education of the Subject, “Health and Physical Education” indicated as a curriculum standard in lower and upper secondary school, and in the health guidance, which carry out in Special Activities and Integrated Studies, etc. Guidance is mainly carried by the teacher for health and physical in health education and school nurse teacher (yogo teacher) in health guidance. In health education we have only limited school hours, and generally use the text book. Some teachers feel resistance to teach medicines because of needs on the special knowledge, however teachers should deal with medicines based on curriculum standard. School pharmacist is a member of school, and has a special knowledge for medicines, and he/she can support teachers as a provider of teaching materials, an adviser, and for a guest teacher. It is important for school pharmacist to understand the contents indicated in curriculum standard and to use glossary to be able to understand for children. In the guidance of health, it is not necessary to teach based on curriculum standard, and it can deal with advanced contents on medicines. However it is important to understand for children what are appropriate contents according to the development stage. To use the packages and instructions for medicines provided at home are good materials for children to have interest the medicines in their guidance. The objectives of education on medicines enable children to cultivate practical abilities for the maintenance and improvement of health.

The Japanese Pharmaceutical Law was revised at the end of July 2002. The important features of this revision are the postmarketing safety scheme, especially for biological products, and reconstruction of the legislation for effective pharmaceutical development. This is based on the national policy to foster life sciences such as genetic research and regenerative medicine for both healthcare improvement and industrial promotion. Such research requires study participants who donate human tissue including abandoned embryos or aborted fetuses, which may touch the human dignity. In particular, fetal stem cell research appears to have unpredictable risks not only to women who undergo abortions but also to societal epistemology. The authors conducted risk-benefit assessment of fetal stem cell research, reviewing the scientific, ethical, legal, and social aspects, including a case study of critical appraisal on a report of the double-blind, sham surgery-controlled trial of implantation of fetal tissues in patients with Parkinson's disease conducted in the USA. It is concluded that risk-benefit assessment with a wide, profound perspective is necessary for advanced biotechnology. Some types of research should not be assessed based only on such utilitarian viewpoints as risk and benefit. Conscientious reflection is necessary to reach a public consensus on which types of human material can be utilized as research or pharmaceutical resources.

The nausea and vomiting that occur as a result of oral iron administration for the treatment of iron-deficiency anemia (IDA) can cause significant physical and emotional stress in patients. Because iron is absorbed from the intestine as ferrous iron, the most widely used treatment for IDA is oral ferrous agents. However, ferrous forms are more toxic than ferric forms because ferrous forms readily generate free radicals. A randomized, double-blind, active-controlled, multicenter non-inferiority study conducted in Japan showed that ferric citrate hydrate (FC) was just as effective as sodium ferrous citrate (SF) in the treatment of IDA, with a lower incidence of adverse reactions such as nausea and vomiting compared with SF. Animal studies have shown that chemotherapy-induced nausea and vomiting (CINV) involves the release of 5-hydroxytryptamine from enterochromaffin cells by free radicals, and that some chemotherapeutic agents cause hyperplasia of these cells. Enterochromaffin cells also contain substance P, which is known to be also closely related to CINV. We found that administration of SF to rats causes hyperplasia of enterochromaffin cells in the small intestine, whereas FC has no effect on enterochromaffin cells. Oral iron agents may induce nausea and vomiting via the effect of ferrous iron on reactive oxygen species production in the intestine and subsequent enterochromaffin cell hyperplasia. Further research to elucidate the detailed mechanism of enterochromaffin cell hyperplasia induced by ferrous iron preparations is needed to develop a treatment for iron deficiency anemia that causes less gastrointestinal damage.

In recent years, home medical care has been strongly promoted. As a consequence, the conditions managed in home medical care have become increasingly diverse. Heart failure is one of the most common disorders after malignant diseases. Patients with chronic heart failure (CHF) are often forced into hospitalization because of the inability to control symptoms with oral medications, even though they hope to stay at home. Recently, we have experienced a case where the patient required continuous administration of dobutamine at home. In order to carry out CHF care at home successfully, it is necessary to adjust the doses of catecholamine and furosemide swiftly in response to changes in patients' conditions. In this case, the patient was able to spend four months at home thanks to the cooperation of a team of a physician, nurses, and pharmacists. Catecholamine-dependent patients with terminal CHF require expensive medical infusion pumps for precise administration. However, the economic assistance to such patients remains insufficient. Furthermore, dobutamine and furosemide injections are not dispensed extramurally, and therefore might become an impediment to the cooperation of the team. In this symposium, I consider and discuss the role of pharmacists in a home medical care team for patients with terminal CHF.

An overview is presented on the reports available so far on sweet potato, Ipomoea batatas, cultivated widely in Polynesia in the pre-Columbian era, with reference to possible ways and presumptive dates of transfer from the Americas to Polynesia, such as (1) Polynesian navigators' travel to Peru, (2) Peruvian fishermen's drift westward, (3) vessel drift, (4) seed drift, (5) root-tuber drift, and (6) transport by birds. The author supports the case (1) as most plausible. Ganshu or Ganchu described in the old Chinese herbal books is identified as Dioscorea esculenta. An introduction of the tuber to China and Japan is briefly mentioned.

We developed a simultaneous detection method of 9 kinds of diuretics in the urine by using thin-layer chromatographic (TLC) method and/or high-performance liquid chromatographic (HPLC) method. The diuretic drugs were extracted from the urine according to modified Tisdall et al. method by use of 1M phosphate buffer and ethylacetate. The TLC method was performed with a commercially available chromatographic plate containing mixed fluorescent substance and isopropyl alcohol-ammonia mixture as a development solvent. The HPLC method was accomplished with UV detection at 271nm. To examine the limit of detection of the methods, normal subjects were individually administered with commercially available tablets of 11 kinds of diuretics, 9 drugs were detected from 24 h urine of normal subjects. However, 2 drugs were not detected. By applying these methods to urine samples of female patients with hypokalemia, furosemide (FD) and trichlormethiazide (TCT) were detected. The chromatographic peak of FD on HPLC method was further assigned by mass spectrometry. The quantitative determination of TCT in the urine was also developed by HPLC method, and the urine concentration in a patient with self-administration of TCT was 0.80μg/ml.

Glaucoma, the leading cause of blindness in adults, is a progressive neurodegenerative disease characterized by retinal ganglion cell (RGC) death. Currently, many intraocular pressure (IOP)-lowering drugs known to affect this disease progression have been developed as therapeutic agents. However, there are many cases of disease progression, even with sufficient IOP reduction. Therefore, newer therapeutic approaches other than IOP-lowering drugs are needed. To elucidate the pathogenesis of glaucoma and to develop therapeutic agents, the evaluation of RGCs is imperative, as their degeneration is the main cause of this disease. However, it is difficult to obtain RGCs from healthy individuals, let alone glaucoma patients. Therefore, research on the pathophysiology of glaucoma and drug discovery has not progressed sufficiently. Recent developments have made it possible to generate induced pluripotent stem (iPS) cells from the blood or skin of glaucoma patients and induce them to differentiate into RGCs to study the pathogenesis of glaucoma. In addition, drug repositioning for ophthalmological diseases such as glaucoma is one of the most active fields. Many of these repositioned drugs have found therapeutic applications in ophthalmology. Here, we introduce the current status of the pharmacological treatment of glaucoma and its prospects.

The hazardous effects due to the insoluble microparticles generated in the injections have been pointed out. To our knowledge, however, there have been no reports about insoluble microparticulate contamination at ampoule opening. Therefore, we performed this study to evaluate the relationship between time and glass particulate sedimentation to examine the effect of swabbing the ampoule neck on particle generation to clarify the relationship between the inner-diameter size of an ampoule and the amount of glass particulate sedimentation to find out the effect of methods for ampule opening, and compare particle contamination in glass ampoule and that of plastic, after ampoule opening and assessed the contribution of material of ampoule to the particle generation. We observed that the glass particulate contamination of accumulation value at a size over 2 μm increased significantly after 60 seconds, the swabbing the neck of the ampoule prior to opening had a negative effect on prevention of glass particulate contamination, the glass particulate contamination was positively influenced by the inner-diameter size of the ampoule, but not by the thickness of the ampoule walls, the particulate contamination derived from glass significantly increased by general method as well as using ampoule open adaptor compared with our method, and the insoluble microparticulate contamination in plastic ampoule was significantly lower than that in glass ampoule. The present findings might provide an useful information to reduce glass particules after ampoule opening performed in clinical practice.

Sedative hypnotics are among the classes of drugs reported to influence falls. However, the effects of the sedative hypnotic drugs, suvorexant and ramelteon, on falls are not well known. Therefore, we conducted this retrospective case-control study to examine the association of the use of these two sedative hypnotics with the risk of falls. Conducted at the Sapporo Medical University Hospital in Japan, our study included 360 patients with fall incidents and 819 randomly selected control patients. Patients in the fall group were significantly older with a lower body mass index, and had a history of falls, disabilities in activities of daily living, cognitive impairment, and delirium. Monovariate analysis revealed that patients in the fall group frequently used ramelteon [odds ratio (OR) 2.38, 95% confidence interval (CI): 1.49-3.81, p<0.001], but rarely used suvorexant (OR 0.66, 95% CI: 0.29-1.39, p=0.317), compared with control patients. Furthermore, multivariate analysis revealed that ramelteon use did not increase the risk of falls (adjusted OR 1.43, 95% CI: 0.82-2.48, p=0.207), whereas suvorexant use significantly decreased the risk of falls (adjusted OR 0.32, 95% CI: 0.13-0.76, p=0.009). Although ramelteon tends to be used in patients at a high risk of falls, it may not increase the risk of falls. In contrast, the use of suvorexant may reduce the risk of falls.

We report a haemodialysis patient with end-stage renal failure whom a pharmacist aided in the management of acyclovir (ACV) encephalopathy, which may have been related to valacyclovir hydrochloride (VACV) administered without sufficient dose reduction. The patient 78 years was admitted with a tentative diagnosis of varicella zoster viral meningitis. A pharmacist suspected ACV encephalopathy related to excessive VACV administration and raised a query with the attending physician. According to the pharmacist's proposal, ACV administration was discontinued and continuous hemodiafiltration (CHDF) was performed. On day 5 of hospitalisation, the consciousness disorder was improved. In this report, we showed the detailed CHDF conditions of the present case, and the contribution of a pharmacist to treating and avoiding ACV encephalopathy was discussed.

Hypoglycemic activity of several kinds of Japanese tea was examined and bancha was found to have potential hypoglycemic activity in streptozotocin-induced hyperglycemic and normal rats. One of the active principles was purified by chromatograph on Toyopearl HW-50F and diethylaminoethyl-cellulose and determined to be heteropolysaccharide (T-b) consisting of arabinose, D-ribose and D-glucose (5.1 : 4.7 : 1.7), which gave a molecular weight of approximately 4×104.

Infection with a variety of viruses induces apoptosis in host cells. This phenomenon may be considered to be a self-defense mechanism to avoid viral propagation. However, the growth of influenza virus is completed before host cells become dysfunctional due to apoptosis. To clarify the physiologic consequences of influenza virus-induced apoptosis, the fate of influenza virus-infected cells was examined in vitro as well as in vivo. Influenza virus-infected cells were engulfed by macrophages in vitro, and virus propagation was almost completely inhibited. This phagocytosis was dependent on the specific recognition of the membrane phospholipid phosphatidylserine exposed on the surface of virus-infected apoptotic cells by macrophages. In addition, the activity of viral neuraminidase expressed at the surface of virus-infected cells was necessary for the maximal level of phagocytosis. When mice infected with influenza virus were administered phagocytosis inhibitors, the level of lethality and inflammation in the lung were augmented. These results show that apoptosis makes influenza virus-infected cells susceptible to phagocytosis by macrophages, and that this leads to a reduction in the extent of influenza pathology.

Zinc is an essential trace element and serves as the active center of approximately 300 enzymes. Therefore, zinc deficiency may be associated with a variety of clinical features such as hypogeusia, hyposmia, growth retardation, dermatitis, alopecia, gonadal hypofunction, abnormal pregnancy, susceptibility to infections, delayed wound healing, impaired glucose tolerance, and increased carcinogenesis. Zinc deficiency was reported to be on the increase in the Nagano Study conducted from 2003 to 2005. Zinc therapy is classified into two categories, zinc-supplementary and -specific treatments. Ordinarily, zinc-supplementary therapy is carried out for the symptoms and diseases caused by zinc deficiency. On the other hand, zinc-specific therapy is applied to obtain copper- and iron-chelating, antifibrotic, and antidiabetic effects. The availability of zinc-specific therapy is now confirmed in humans and animals. Hereafter, the safety of zinc therapy needs to be examined further.

Reactive oxygen species (ROS) are highly reactive molecules generated during mitochondrial respiration and under various environmental stresses, and cause damage to DNA, proteins, and lipids, which is linked to a wide variety of pathologies. However, recent studies have revealed the physiological importance of ROS as signaling molecules, which play crucial roles in the maintenance of cellular functions and homeostasis. According to the extent and duration of ROS generation, ROS-mediated oxidation-reduction (redox) signaling (ROS signaling) is tightly regulated by various molecules and post-translational modifications (PTMs), for inducing appropriate cellular responses. Dysregulation of ROS signaling causes cellular malfunctions, which are also linked to various diseases, such as cancer, neurodegeneration and inflammatory diseases. In this review, we focus on a ROS-responsive protein kinase apoptosis signal-regulating kinase 1 (ASK1) that belongs to the mitogen-activated protein (MAP) kinase kinase kinase (MAP3K) family, and activates the c-jun N-terminal kinase (JNK) and p38 MAP kinase pathways, which consequently induces various cellular responses, including apoptosis and inflammation. Here, we introduce a novel regulatory mechanism and the pathophysiological significance of ASK1 activation. We found that an E3 ubiquitin ligase TRIM48 orchestrates fine-tuning of ROS-induced ASK1 activation mediated by multiple types of PTMs, including ubiquitination, methylation, and phosphorylation. We also found that trans-fatty acids (TFAs) enhance ROS-dependent ASK1 activation induced by extracellular ATP, a damage-associated molecular pattern (DAMP), and thereby promotes apoptosis, which possibly contributes to the pathogenesis of TFA-related diseases including atherosclerosis. Thus, this review provides recent advances in the study of ROS signaling, especially ROS-ASK1 signaling pathway.

Health literacy is defined as the ability to obtain, evaluate, and scrutinize health information and make appropriate decisions and actions. The spread of the Internet means that medical and drug information is becoming increasingly accessible to patients. However, there is also a large amount of inappropriate and biased medical- and drug-related information on the Internet. Therefore, patients require a high level of health literacy to ensure the effectiveness and safety of pharmacotherapy. In particular, outpatients need a high level of health literacy because they use their own medications without the supervision of healthcare professionals. In this article, I discuss the situation of health literacy and access to pharmaceutical information on the Internet in Japan. Furthermore, issues related to providing drug information to specific populations are explained using the example of chronic kidney disease. It is essential for all pharmaceutical information stakeholders to work together to solve these problems.

Cell proliferation is regulated through a transition between the G0 phase and cell cycle. We isolated a mammalian temperature-sensitive mutant cell line defective in the function from the G0 phase to cell cycle. Senescent human somatic cells fail to enter into the cell cycle from the G0 phase with stimulation by any growth factor. Telomere shortening was found to be a cause of cellular senescence, and reexpression of telomerase immortalized human somatic cells. Immortalized human somatic cells showed normal phenotypes and were useful not only for basic research but also for clinical and applied fields. The importance of p53 and p21 activation/induction i now well accepted in the signal transduction process from telomere shortening to growth arrest, but the precise mechanism is largely unknown as yet. We found that the MAP kinase cascade and histone acetylase have an important role in the signaling process to express p21. Tumor tissues and cells were found to have strong telomerase activity, while most normal somatic human tissues showed very weak or no activity. Telomerase activity was shown to be a good marker for early tumor diagnosis because significant telomerase activity was detected in very early tumors or even in some precancerous tissues compared with adjacent normal tissues. Telomere/telomerase is a candidate target for cancer chemotherapeutics, and an agent that abrogated telomere functions was found to kill tumor cells effectively by inducing apoptosis whereas it showed no effect on the viability of normal cells.

Community pharmacists can provide effective pharmaceutical care by questioning the physicians about their prescriptions. The regulatory authority (Ministry of Health, Labour and Welfare or the like) has been issuing instructions/advice to health insurance-covered pharmacies about the nature of questions to be asked to physicians under the national health insurance system. However, this practice has been facing similar kind of problems almost every year. To identify the reasons for repetition of the problems and facilitate proper application of drug therapy at hospitals, we recently examined the nature of questions asked to physicians by conducting a survey of 165 health insurance-covered pharmacies belonging to 8 district branches of the Japan Pharmaceutical Association. When the pharmacists were asked to express their view whether each of the 18 sample questions included in the past surveys was actually necessary, the most frequent answer from the respondents (n=1980) was “neutral” (42.9%), followed by “unnecessary” (29.0%) and “necessary” (26.6%). Further, 55.5% respondents answered that it is necessary to refer to publications of the concerned fields (guidelines, etc.) when questioning the prescriptions. However, the responses about the possible reasons for judging the necessity of the questions suggested that sometimes the pharmacists failed to understand the details of such publications. The results from this study suggest that a high percentage of community pharmacists believed that there was little need to ask questions about prescriptions if the suggestions made by the regulatory authority about the relevant questions were taken into account. Further, our study findings suggested that pharmacists working at clinics cannot present a clear-cut rationale for their judgment about the necessity of asking questions about prescriptions under the current circumstances where sufficient information collection and the evaluation of need for asking questions about prescriptions are not possible.

Drugs are sometimes covered with oblate or agar jelly. It is said that the medicinal effect of drugs covered with oblate is slow, but no studies have reported results confirming this. Therefore, we examined the dissolution behavior when the drug was covered with oblate or agar jelly. Three types of commercially available formulations of benzodiazepine were used: medazepam sugarcoated tablets, prazepam uncoated tablets, and clorazepate dipotassium capsules. Dissolution tests were performed using solutions of pH 1.2 and 5.6 to simulate normal gastric juice and gastric anacidity, respectively. Drugs covered with oblate were tested by the paddle method, and those covered with agar jelly were tested using the rotating basket method. Dissolution of clorazepate capsules not covered with oblate increased by approximately 10% when the pH was adjusted from 1.2 to 5.6, while those of medazepam and prazepam tablets decreased by approximately 40-60%. In contrast, the dissolution decreased significantly at both pH values for each drug covered with oblate. Dissolution further decreased when the amount of oblate was doubled. No detectable dissolution of medazepam tablets or of clorazepate capsules occurred when the drug was covered with agar jelly.
