The retina has been regarded as 'an approachable part of the brain' for investigating central nervous system (CNS). The optic nerve injury is a well-accepted model to study the mechanisms of neural degeneration and/or axonal regeneration after trauma in the CNS. Nitric oxide (NO) is a gaseous messenger molecule biosynthesized from L-arginine and molecular oxygen by NO synthase. Many reports suggest that excess production of NO plays a crucial role in neuronal cell death including in death of retinal ganglion cells (RGCs). In contrast, several lines of evidence indicate that NO can prevent neuronal death. In general, NO mediates neuroprotection through two main signaling pathways: the NO/cyclic guanosine monophosphate (cGMP) pathway and the S-nitrosylation pathway. Especially, whether S-nitrosylation of proteins promotes RGCs survival and its axonal regeneration after injury is unclear. Thus, we focused on the S-nitrosylation-dependent mechanism of RGCs survival and axonal regeneration by NO after nerve injury.

In recent years, antimicrobial resistance bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) have become a global problem. One of the countermeasures is to optimize the use of antimicrobial drugs, specifically to optimize the dosage and administration based on the therapeutic drug monitoring (TDM) and pharmacokinetics (PK)/pharmacodynamics (PD) theory. On the other hand, in clinical practice, clinical-pharmacometrics can be used for optimized management of individual patients of pharmaceutical products. Therefore, we aimed at individual optimization of infectious disease treatment for antimicrobial resistant bacteria, and tried a series of flows from model construction to clinical application, that is, practice of clinical pharmacometrics. In the context of individual optimization and optimization management of drug therapy in the medical field, it is considered that hospital pharmacists can contribute to the improvement of infectious disease treatment of antimicrobial resistance bacteria by contributing to the optimization of administration method. In addition, clinical pharmacometrics can be applied not only to antibacterial drugs but also to all drugs, and can be said to be a useful method for quantitatively evaluating the promotion of individualized administration methods for patients.

Denosumab is a fully monoclonal antibody against the receptor activator of nuclear factor kappa-B ligand (RANKL), and prevents skeletal-related events by bone metastasis. Hypocalcemia is the most typical adverse effect of denosumab use. We have developed a management system for the more efficient and safer management of denosumab administration, and evaluated pharmaceutical interventions for the better control of hypocalcemia. All pharmaceutical interventions in the system from April 2016 to March 2020 were retrospectively evaluated. We have also assessed the incidence of hypocalcemia in 158 patients who were administered denosumab for six months or more in the period. A total of 282 pharmaceutical interventions (7.0% of the total administration) were conducted. The most conducted intervention was regarding hypocalcemia, which involved the suspension of the injection and/or the increase of calcium and vitamin D supplement with 65% adoption and 17% temporary treatment suspensions. Other interventions were about hypercalcemia, request of laboratory examination and ordering supplements, dental consultation, and poor renal function. A total of 199 interventions (70.6%) were adopted, with 33 administrations suspended. The frequency of hypocalcemia was 27.8% with just one patient having grade 2 hypocalcemia, suggesting that there were no severe cases. Moreover, hypocalcemia was significantly normalized following pharmaceutical intervention and/or handling by physicians (p=0.02) according to the system. Conversely, the normalization rate in hypercalcemia did not differ according to the countermeasures. In conclusion, pharmaceutical interventions according to our management system benefit safe denosumab treatment, especially in severe hypocalcemia prevention.

Separation of the dispensing function and the prescribing function, Iyaku Bungyo, has been progressing in Japan. We are now witnessing the advent of a new society where patients select pharmacists and their satisfaction is recognized as one of the healthcare outcome indicators. It is necessary to clarify which factors affect patients' satisfaction with the services provided at community pharmacies and how they do so. A survey was conducted among 104 community pharmacies and their patients around the Tokyo metropolitan area in Japan. The questionnaire comprised 11 items (observed variables), each with a five-grade scale. With the transformed data-oriented pharmacy, the percentage of being not unsatisfactory was examined in two multivariate analyses of the relation and structure of patient satisfaction with a community pharmacy. Structural equation modeling (SEM) with factor analysis (FA) was performed using the observed variables and latent factors. Multiple regression analysis was performed with comprehensive satisfaction as an independent variable, examining the factors that affect comprehensive satisfaction with the pharmacy. The result of the FA indicated three latent factors of instruction on the use of drugs, quality of staff, and environment, based on which SEM model was constructed with a relatively high goodness of fit index. The result of multiple regression analyses indicated almost all variables such as satisfaction with reception by the pharmacist affected the comprehensive satisfaction, but privacy did not show a significant effect. These results, notably the relationship between each variables and latent factors, suggested the importance of higher skills of pharmacists, service qualities at pharmacies, and their functions adjusted to the community.

Training pharmacy students to become future clinical pharmacists is an important mission in the 6-year school of pharmacy curriculum in Japan. Since 2014, we have conducted an on-campus practical training program to develop basic skills in clinical pharmacy for third-year pharmacy students at Meiji Pharmaceutical University. This training program includes searching for and retrieving drug information; interpretation of laboratory findings, vital signs, and physical examinations; literature appraisal; and professional writing. These training sections are arranged in the above-mentioned order to facilitate effective understanding of each. In the literature appraisal section, each student group is assigned a report on a prospective controlled study of a given drug published in English and reads it critically according to the literature appraisal worksheet. Then the group writes a monograph on the drug described in the report based on the literature and other information. Thereafter, all students are reshuffled into new groups so that students who were assigned different drugs are placed together, in the so-called jigsaw learning method. Students then discuss which two or three drugs in a specific pharmacological class should be adopted in the hospital formulary according to the knowledge gained through this training program series. The themes were novel oral anticoagulants in the 2014 academic year, dipeptidyl peptidase 4 inhibitors in 2015, and 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors in 2016. Although there are some problems that need to be resolved in the future, this approach appears effective in helping students build drug information skills as a basic competence of clinical pharmacists.

Circulating counterfeit medicines in the market is a public health threat. Counterfeit medicines become common problem, not only in developing countries, but also in industrialised countries, as internet has made them more accessible. In Japan, the recent survey on the medicines purchased through on-line pharmacy (targeting Japanese consumers) showed that the majority of erectile dysfunction (ED) medicines imported by individuals in Japan were counterfeit version. The survey of Japanese consumers, who privately imported medicines through on-line pharmacy, indicated that 16% of these consumers experienced adverse events associated with these products. Not only that it is just fake brand, but fake medicines may even cause health hazard. The counterfeit version of Avastin recently detected in the United States became a serious threat for those who desperately need these medicines for life-threatening disease. The Japanese regulatory authorities have provided risk information of counterfeit medicines to general public, as well as monitored on-line pharmacies and conducted enforcement action where necessary. However, more resources of compliance activity should be allocated to respond to the situation of growing threats of counterfeit medicines. Purchasing medicines from abroad through unauthorised channel is the major source of counterfeit medicines. It is essential to prevent circulation of counterfeit medicines through international collaboration of various regulatory authorities. To address these problems, the World Health Organization (WHO) has launched a new Member States Mechanism (MSM) to build network of the authorities. Also, INTERPOL (ICPO) initiated globally concerted enforcement actions (Operation Pangea) against pharmaceutical crime as well as built partnership with pharmaceutical industry to create Pharmaceutical Crime Programme. It is also necessary to prevent consumers encountering counterfeit medicines and to prevent health hazard. The Ministry of Health, Labour and Welfare (MHLW) has been actively involved in prevention and educational activities such as public awareness campaign. MHLW started anti-counterfeit medicines and new psychoactive substance project from February 2013, which centrally collects information about counterfeit medicines, in particular, and provides the risk information more effectively to the public. Japanese Government will work together with international community and contribute to combating counterfeiting through public and private partnership.

Opsins (also called animal rhodopsins) are universal photoreceptive proteins that provide the molecular basis of visual and nonvisual photoreception in animals, including humans. Opsins consist of seven helical α-transmembrane domains and use retinal, a derivative of vitamin A, as a chromophore. In many opsins, light absorption triggers photo-isomerization from 11-cis retinal to all-trans retinal, resulting in activation via dynamic structural changes in the protein moiety. Activated opsins stimulate cognate trimeric G proteins to induce signal transduction cascades in cells. Recently, molecular and physiological analyses of diverse opsins have progressively advanced. This review introduces the molecular basis and physiological functions of opsins. Based on the functions of opsins, I will discuss the potential of opsins as target molecules to treat and prevent visual and nonvisual diseases such as sleep disorder and depression.

At small or mid-sized medical institutions, such as Japanese community hospitals, adequate infectious disease physicians (IDP) are lacking, mainly due to shortages of full-time pharmacists and IDPs who support antimicrobial stewardship team (AST) activities. With our hospital AST, we developed a multidisciplinary approach based on the interim reports of culture results or detected resistant bacteria for physicians, which are written by pharmacists and clinical laboratory technicians. At the AST conference, a pharmacist works as a chairman and reviews abstracts of cases which need to be discussed. We performed a retrospective analysis of the process and outcome of AST implementation, and introduced the use of reduction data for our hospital, obtained from Japan Surveillance for Infection Prevention and Healthcare Epidemiology (J-SIPHE). This program is important for pharmacists to promote the diagnostic process and comprehensive judgment necessary for bedside practice with infectious disease cases. We offer opportunities for pharmacy students to participate in the AST conference to learn how pharmacists consult with doctors about diagnosis and treatment. At present, the cooperation between AS and diagnostic stewardship (DS) has been emphasized, and improvements in a pharmacist's overall judgment regarding infectious disease cases are required to appropriate antimicrobial use. In addition, improving communication skills is essential for building a multidisciplinary approach. Regardless of the size of the facility, the role of pharmacists in AST should be implemented for the guidance of pharmacy students, which will help develop and secure future human resources at the facility.

Since 1997, Chubu Rosai Hospital has been establishing the proper use of various antibacterial drugs through the activities of an infection control team (ICT), introduction of a notification system for specific antibacterial drug use, and intervention of ward pharmacists for individual cases. There is no infectious disease department, and we have been working closely with each other on multiple occupations. As an initiative, we established the Nagoya Southern Infection Countermeasures Meeting in 2006 and conducted antimicrobial use and resistance (AUR) surveys to promote the proper use of antimicrobial agents within the area. In April 2018, we formed an antimicrobial stewardship team (AST) and initiated activities. In addition, an AST pharmacist can share the AST results with the ward pharmacist, for proper use of antibacterial drugs and for early monitoring of infectious disease treatment and appropriate intervention, thus improving the efficiency of the ward pharmacist's work. This program will also lead to the development of training programs for the younger generation of pharmacists.

Since 2018, high expectations have been placed on the efforts of pharmacists in infectious disease diagnostic aid via Japan's antimicrobial stewardship team (AST). We will explain this while describing the process of diagnostic aid at our institution, a university hospital, and taking into account the point of view of what is required of pharmacist by infection control doctors when performing infectious disease diagnostic aid as well. At our hospital, we implement AST rounds as infectious disease diagnostic aid for positive blood cultures, bacterial culture results, fever, long-term administration of anti-bacterial medication, example consultation cases, etc. The number of rounds has been increasing over time, totaling 5654 cases in 2018. When performing infectious disease diagnostic aid, failure to also bear in mind infection control measures can result in failed treatment and outbreaks, so AST must coordinate with infection control team (ICT). Furthermore, when engaging in infectious disease diagnostic aid, pharmacists must also participate in clinical research in order to improve the quality of treatment. Although it also depends on the facility environment they are affiliated with, it would seem to be necessary for pharmacists to verify the knowledge obtained from clinical data using a fundamental approach. Moreover, conducting education for the doctor, pharmacist, and nurse trainees who make up their fellow and future staff is another vital role of AST pharmacists.

Over the last decade, many public institutions have emphasized the importance of antimicrobial stewardship (AS) in reducing the spread of antimicrobial resistance. In our facility, we have tackled AS that has adapted to clinical practices since 2015. In many facilities, especially university hospitals, multidrug-resistant bacteria, such as methicillin-resistant Staphylococcus aureus and extended-spectrum β-lactamase-producing bacteria, may cause infections. Considering this, we recommend prompt treatment with suitable antibiotics and dosage. In AS teams, pharmacists are responsible for administering pharmacotherapy, including optimal dosage for each patient. Therefore, they should assess their patients carefully, implement thorough therapeutic drug monitoring, and utilize the information obtained from these assessments to administer optimal pharmacotherapy. However, optimal pharmacotherapy also requires a correct diagnosis. Although diagnostic stewardship is not a pharmacist's work, it is a great opportunity for pharmacists to learn how expert physicians think. Based on the type of situation above, we train younger pharmacists on the job.

Emergency contraceptive (EC) pills are used to prevent pregnancy after unprotected sexual intercourse. Levonorgestrel is an EC pill, which has been only approved in Japan; it is more effective the sooner it is used after intercourse and safe without serious side effects. EC pills are already available at accessible community pharmacies in more than 90 countries around the world. In Japan, citizens have signed a petition calling for the sale of emergency contraceptives at community pharmacies. However, little is known about the thoughts of pharmacists who engage with patients and sell medicines at pharmacies. Therefore, we conducted a web-based cross-sectional survey to determine the level of preparation in community pharmacies and the awareness of pharmacists regarding the sale of EC pills. A total of 1338 pharmacists responded to the survey from November 7, 2020, to December 16, 2020. In terms of the level of preparation for selling EC pills at pharmacies, 1067 (83.9%) respondents cited “lack of preparation of medical questionnaires and explanatory materials”, and 975 (76.7%) respondents cited “lack of knowledge of pharmacists” as the most common reasons that were “barriers to EC pill sales at pharmacies”. In terms of confidence level, only 289 (22.7%) respondents were confident about conducting the necessary checks while administering medicine. On the other hand, 944 (74.3%) respondents agreed to be able to sell EC pills at their pharmacies. The survey revealed that most of the pharmacists who participated in the survey believe that it is possible to sell EC pills in pharmacies.

The dosage of cisplatin is adjusted according to creatinine clearance (Ccr) estimated by the Cockcroft-Gault formula, which is commonly used as a marker for renal function. It is known that different serum creatinine (Scr) levels are reported depending on the analytical methods utilized such as the Scr level by the enzyme method being lower than that by the Jaffe method. Although the enzyme method is used in Japan, most drug dosages, including cisplatin, are adjusted according to the estimated Ccr using the Jaffe method-based Scr level. The purpose of this study was to investigate whether assessment of renal function with or without Scr adjustment affects cisplatin-based chemotherapy in cervical cancer patients. The patients were divided into two groups, normal (Ccr≥60 mL/min with adjusted Scr) and false normal (Ccr<60 mL/min with adjusted Scr, but Ccr≥60 mL/min with non-adjusted Scr). The false normal group had significantly higher rates of cisplatin dose reduction after the second course than the normal group (p<0.05). Leukocytopenia and Grade 2 or higher neutropenia were significantly more common in the false normal group than in the normal group (p<0.05). These results suggest that evaluation of renal function using the adjusted Scr is important for the accurate dosage of cisplatin and that it helps to improve the patient's quality of life. Further investigations may provide useful information for accurate and safe cisplatin-based chemotherapy for cancer patients.

It has been recommended that active learning methods, such as team-based learning (TBL) and problem-based learning (PBL), be introduced into university classes by the Central Council for Education. As such, for the past 3 years, we have implemented TBL in a medical therapeutics course for 4-year students. Based upon our experience, TBL is characterized as follows: TBL needs fewer teachers than PBL to conduct a TBL module. TBL enables both students and teachers to recognize and confirm the learning results from preparation and reviewing. TBL grows students' responsibility for themselves and their teams, and likely facilitates learning activities through peer assessment.

Pure chloroform is known to be decomposed readily in the presence of air, even in the dark, although then very slowly, but in the absence of oxygen. In the first stage of the decomposition, chloroform produces an intermediate peroxide, Cl3COOH, which disapears in the second stage to yield chlorine, phosgene, and hydrochloric acid through two courses (a) and (b) as illustrated in chart 1.-1 The mechanism of phosgene formation was evidenced by the fact that decomposed chloroform produced diphenylurea by reaction with aniline and the reaction of the decomposed trichloroethylene or tetrachloroethane with aniline produced the same dichloroacetanilide, as shown in chart 1.-2 and 3 Ethanol added to the decomposed chloroform showed apparently a catalytic effect decomposing the peroxide to Cl2 or COCl2 through the courses shown by chart 1.-1-a and b Alcohols except methanol, ethers except dioxane, phenols, and hydrocarbons were useful as a stabilizer for chloroform, while acetone, acetic acid, ethyl acetate, and benzene were useless. In alcohols, the stabilizing effect became stronger with increasing number of carbon atoms in the molecule. It is interesting that hydrocarbons such as hexane and decane possess a marked effect as a stabi1izer. It is difficult to understand how the presence of so small an amount of stabilizer could prevent the decomposition of chloroform but it may not be unreasonable to assume the following : 1) It is considered that the stabilizers prevent the decomposition of chloroform in its primary stage, by the fact that a small amount or the stabilizer prevents the formation of even a trace of Cl- under conditions most favorable to decomposition : 2) The stabilizers containing hydrocarbons act as an anticatalyst in unchanged form, because they are so resistant to chemical change : and 3) The fact that various substances of different types such as alcohols, ethers, phenols, and hydrocarbons are useful as a stabilizer shows that the mechanism of this stabilization is not simple.

Cellular transport systems for both essential and toxic trace elements remain elusive. In our studies on the transport systems for cadmium (Cd), we found that the cellular uptake of Cd is mediated by the transporter for manganese (Mn). We identified ZIP8 and ZIP14, members of the ZIP zinc (Zn) transporter family, as transporters having high affinities for both Cd and Mn. Notably, the uptake of Cd into rice root from soil is mediated by a transporter for Mn as well. We found that ZIP8 is highly expressed at the S3 segment of the kidney proximal tubule and can transport glomerulus-filtered Cd and Mn ions in the lumen into epithelial cells of the proximal tubule, suggesting that ZIP8 has an important role in the renal reabsorption of both toxic Cd and essential Mn. Mutations in ZIP8 and ZIP14 genes were found in humans having congenital disorders associated with the disturbed transport of Mn, although ZIP8 mutation causes whole-body Mn deficiency while ZIP14 mutation causes Mn accumulation in the brain. Mutations in ZnT10, a Zn transporter responsible for Mn excretion, also cause hyperaccumulation of Mn in the brain. Results of genome-wide association studies have indicated that ZIP8 SNPs are involved in a variety of common diseases. Thus, ZIP8, ZIP14, and ZnT10 play crucial roles in the transport of Mn and thereby control Mn- and Cd-related biological events in the body.

Skeletal muscle is a promising target tissue for the gene therapy of both muscle and non-muscle disorders. Gene transfer into muscle tissue can produce a variety of physiologically active proteins and may ultimately be applied to treatment of many diseases. A variety of methods have been studied to transfer genes into skeletal muscle, including viral and non-viral vectors. Recently, we have developed the polyethyleneglycol (PEG)-modified liposomes entrapping echo-contrast gas known as ultrasound (US) imaging gas. We have called the liposomes “Bubble liposomes” (BLs). We have further demonstrated that US-mediated eruption of BLs loaded with naked plasmid-DNA is a feasible and efficient technique for gene delivery. In this study, to assess the feasibility and the effectiveness of BLs for the gene therapy of disorders, we tried to deliver therapeutic genes (anti-inflammatory cytokine; IL-10 or anti-angiogenic factor; hK1-5) into skeletal muscles of arthritis or tumor model mice by the gene delivery system with BLs and US exposure. As a result, their disease symptom was efficiently improved by the systemic secretion of therapeutic proteins. Thus, this US-mediated BLs technique for muscle gene transfer may provide an effective noninvasive method for arthritis or cancer gene therapy in clinical use. In addition, it may be applicable for the gene therapy of other non-muscle and muscle disorders.
