[Objectives] Psychological factors are mentioned as one of the causes of menstrual pain and menstruation-associated symptoms. In this study, the relationship between menstrual pain, menstruation-associated symptoms, and personality was examined.
[Methods] We targeted women who were menstruating and had provided informed consent. A questionnaire was conducted to obtain information on age, height, weight, degree of menstrual pain, menstruation-associated symptoms, and new personality inventory. Correlation analysis of Spearman was conducted on the relationship between menstrual pain, menstruation-associated symptoms, and personality.
[Results] We distributed questionnaires to 250 persons and obtained responses from 166 persons. "Anxiety" correlated with menstrual pain and multiple factors of menstruation-associated symptoms, "depression" correlated with multiple factors of menstruation-associated symptoms. In addition, "aggression," "inferiority complex," and "non-cooperativeness" correlated with negative emotional factors of menstruation-associated symptoms.
[Discussion] For "anxiety" and "depression," it was speculated that the symptoms became stronger due to poor circulation and serotonin deficiency during menstruation. In addition, the depressive aspects of "aggression," "non-cooperativeness," and "inferiority complex" were also considered to have an influence on negative emotional factors of menstruation-associated symptoms.
[Conclusions] "Anxiety" correlated with menstrual pain and multiple factors of menstruation-associated symptoms, and "depression" correlated with multiple factors of menstruation-associated symptoms.
The domestic production of moxa used in Japanese moxibustion therapy has decreased. Therefore, it is assumed that improved productivity of moxa and cultivation of Artemisa princeps Pamp. (Yomogi) is necessary for stable production of moxa. In this study, the production rate of moxa processed from green leaves, its chlorophyll content, maximum temperature of combustion, morphology, and yield of families collected from 127 domestic spots were investigated. They were evaluated to determine which family was suitable for use in moxibustion. As a result of principal component analysis on the morphological evaluation, 22 families were extracted as they were easily harvestable and were produced over a large area. They had a high productivity rate for moxa, and contained more than the standard weight in dry leaves among all the families. It was confirmed that these extracted families included families that have not been used so far in addition to families collected in conventional areas. These results suggest that production using extracted families can improve the domestic production of Artemisa princeps of moxa.
[Objective] The purpose of this study was to investigate the effects of acupuncture on exercise-induced prolongation of information processing and decrease in attentional resource allocation, excluding the placebo effect.
[Design] Crossover, double-blind randomized controlled trial
[Settings] Tokyo Ariake University
[Subjects] Fifteen healthy men aged 21.1 ± 0.9 years
[Methods] We used a handgrip exercise for exercise loading. The handgrip was maintained for six seconds at an intensity of 40% of the maximal voluntary contraction (MVC), followed by rest for four seconds. This was alternately repeated and continued until the subject was incapable of exerting a grip strength of 40% of the MVC. To induce P300, an auditory oddball paradigm was used, and P300 was measured before and after the handgrip exercise. In the same subjects, thumbtack needle (TN) intervention (TN group) and placebo thumbtack needle (PTN) intervention (PTN group) were performed in random order. TN or PTN was applied to ST36, HT7, and GV14 before the handgrip exercise. After the experiment, we asked the subjects and practitioner about the intervention (TN or PTN). The allocation was conducted by a third party who did not participate in the experiment, and the subjects, practitioner, and measurer completed a series of all the experiment procedures and were blinded to the results.
[Outcomes] The indicators for measuring the main outcomes were P300 latency and amplitude. reaction time, and masking were indicators for secondary outcomes.
[Results and Conclusion] In the PTN group, P300 latency was increased significantly and P300 amplitude was decreased significantly after the handgrip exercise. In the TN group, no significant changes were observed in P300 latency and amplitude after the handgrip exercise. In both groups, reaction time was considerably slower after the handgrip exercise. The k value indicating the degree of agreement between the actual (genuine or placebo) and guessed intervention assignment was k = -0.06 for the practitioner and k = 0.66 for the subjects. No adverse events were found in this study.
[Conclusions] The index changes in the TN and PTN in this study were the same as in our previous studies, and acceptable reproducibility was observed. However, the k values indicated that subject masking was inadequate. In the future, the reliability and validity of PTN must be investigated further.
