The objectives of this study were to investigate the effects of Hericium erinaceum (Yamabusitake) and Grifola frondosa (Maiteke) on the proliferation for EL4-tumor and immunoregulatory function by flow cytometory.
It was found that Yamabushitake and Maitake tend to inhibit the proliferation of EL4-tumor individually. In the flow cytometory analysis, Maitake-treatment showed the preserve effect against the depression effect by bearing EL4-tumor on cytotoxic T cell and NK-cell from spleen cell. This effect was shown more clear in the group of mixture Yamabusitake and Maitake.

Objective: In Japan, the healthcare authority encourages physicians to prescribe generic drugs in order to reduce the copayments by the patients for pharmaceutical expenses and to improve the financial status of the national medical insurance system.  In accordance with this governmental policy, we have been actively involved in switching original to generic formulations.  Thus, Utemerine® 50 mg injection was replaced with Ritodrine hydrochloride 50 mg intravenous injection produced by Nichiiko.  There have been some reports on adverse events caused by the generic formulations of Ritodrine hydrochloride.  Factors contributing to these adverse effects may include different additives and/or vehicles and the exemption of demonstrating some conditions for approval, including clinical trials.  Therefore, in order to assess the efficacy and safety of a generic formulation of Ritodrine hydrochloride injection formulation compared with the original formulation and to decide on its continued use, we carried out a retrospective cohort study.
Methods: We carried out a retrospective cohort study in order to assess the efficacy and safety of a generic formulation of Ritodrine hydrochloride injection formulation compared with the original formulation.
Results: There were no significant differences in the length of hospital stay, rate of emergency transport to other institutions, gestational week of delivery, rate of stillbirth, rate of abortion, or incidence of adverse events between the two formulations.
Conclusion: Our results may contribute to the safe and secure use of the generic formulations of Ritodrine hydrochloride in the current situation of the increasing use of generic drugs in health care.  Although there are some limitations in our study, the results suggest that there are no particular problems with the continued use of Ritodrine hydrochloride 50 mg intravenous injection produced by Nichiiko.

The preparation for influenza pandemic has become very important. However, no standardized educational package against pandemics has been established to date. We developed a simulation–based education drill for Japanese medical students based on the package developed by U.S. medical school. The drill was adapted to 201 medical students, and was evaluated by self–administered questionnaires.
1)More than 90% of the students indicated that the use of this drill is appropriate to experience a simulated pandemic situation, and to learn skills and attitudes such as teamwork and communication.
2)Up to 65% of the students answered they learned a "very clear image" for the "Importance of working as a team with other professionals".
3)The results suggest that this simulation–based education drill make the students aware not only of the need for the preparation for pandemic but also the importance of team–based approach.

The frequencies of the urinary complaints oa the outpatients (male 188, female 339, average age 59.2+14.9) of the five acupuncture clinics were surveyed. The elder patients showed the higher frequencies of the urinary complaints. The frequencies of the complaints were as follows: nocturia (25.8%), urinary urgency (17.7%), stress incontinence (16.3%), sense of residual urine (15.2%), protracted micturition (12.0%), and retarded micturition (11.3%), respectively. The nocturia was accompanied with the majority of the other urinary complaints. These results suggest that the survey of the patient's complaint of nocturia is useful.

Although it is not yet common, certified Kampo (traditional Japanese medicine) doctors and acupuncturists are cooperating with each other to provide traditional medical treatment for patients in some general hospitals in Japan. In other hospitals, however, Kampo and acupuncture-moxibustion have not been introduced, and doctors only treat patients using modern Western medicine. Many doctors must already be aware that modern Western medicine is not the only approach for the treatment of patients, but they do not make any efforts to improve the situation by adopting traditional medicine. Here, we give some examples of hospitals in which acupuncture treatments are routinely provided, having a favorable effect on both patients as well as the hospitals themselves. We believe that these examples give us a good opportunity to consider the future of an ideal medical system in which modern Western medicine and traditional Japanese medicine are successfully integrated.

BACKGROUND: Leukotriene receptor antagonists have been used to prevent virus-induced asthma exacerbations in autumn. Its efficacy, however, might differ with age and sex. OBJECTIVE: This study aimed to investigate whether pranlukast added to usual asthma therapy in Japanese children during autumn, season associated with the peak of asthma, reduces asthma exacerbations. It was also evaluated the effect of age and sex on pranlukast's efficacy. METHODS: A total of 121 asthmatic children aged 1 to 14 years were randomly assigned to receive regular pranlukast or not according to sex, and were divided in 2 age groups, 1–5 years and 6–14 years. The primary outcome was total asthma score calculated during 8 weeks by using a sticker calendar related to the days in which a child experienced a worsening of asthma symptoms. This open study lasted 60 days from September 15 to November 14, 2007. RESULTS: Significant differences in pranlukast efficacy were observed between sex and age groups. Boys aged 1 to 5 years had the lower total asthma score at 8 weeks (p = 0.002), and experienced fewer cold episodes (p = 0.007). There were no significant differences between pranlukast and control group in total asthma score at 8 weeks (p = 0.35), and in the days in which a child experienced a worsening of asthma symptoms (p = 0.67). CONCLUSION: There was a substantial benefit of adding pranlukast to usual therapy in asthmatic children, especially in boys aged 1 to 5 years, during autumn season.

roblem: Once COVID-19 vaccines were rolled out, there was a need to monitor real-world vaccine effectiveness to accumulate evidence to inform policy and risk communication. This was especially true in Japan and the Philippines, given historical issues that affected vaccine confidence. Context: Neither country had public health surveillance that could be enhanced to evaluate vaccine effectiveness or readily available national vaccination databases. Action: Study groups were established in multiple health-care facilities in each country to assess vaccine effectiveness against both symptomatic infection and severe disease. Outcome: In Japan, multiple study reports were published in Japanese on the website of the National Institute of Infectious Diseases and presented at the national government’s advisory board. Nationwide media coverage facilitated transparency and increased the confidence of the government and the public in the vaccination programme. In the Philippines, the launch of the study was delayed so as to align the research plan with the interests of various stakeholders and to obtain institutional review board approval. Ultimately, the studies were successfully initiated and completed. Discussion: There were four main challenges in conducting our studies: finding health-care facilities for data collection; obtaining exposure (vaccination) data; identifying epidemiological biases and confounders; and informing policy and risk communication in a timely manner. Preparedness during inter-emergency/epidemic/pandemic periods to rapidly evaluate relevant interventions such as vaccination is critical and should include the following considerations: (1) the establishment and maintenance of prospective data collection platforms, ideally under public health surveillance (if not, clinical research networks or linked databases); (2) uniform and practical protocols considering biases and confounders; and (3) communication with stakeholders including institutional review boards.
