Objective: Celecoxib has been reported to enhance the action of warfarin by inhibiting CYP2C9, its major hepatic drug-metabolizing enzyme, but sufficient information about the mechanism has not been obtained, especially in Japan.
Methods: A study was conducted to investigate the prothrombin time international normalized ratio (PT-INR) and the warfarin sensitivity index (WSI) before and after concurrent administration of celecoxib, as well as the Drug Interaction Probability Scale (DIPS) scores to determine causality with drug interactions, in patients commencing concurrent therapy with celecoxib and warfarin at Kanagawa Prefectural Keiyukai Keiyu Hospital during the 4-year period from October 2011 to September 2015.
Results: Analysis of 18 patients showed that the PT-INR increased significantly from 1.53±0.43 before concurrent therapy to 2.18±1.01 after concurrent therapy (p=0.0101).  The WSI also increased significantly from 0.76±0.50 before concurrent therapy to 1.01±0.65 after concurrent therapy (p=0.0044).  According to the DIPS scores, the causal relation was not rated as “Highly Probable” in any of the patients, while it was considered to be “Probable” in 3 patients, “Possible” in 10 patients, and “Doubtful” in 5 patients.
Conclusion: The findings of this study suggested that when celecoxib treatment is initiated in patients who are already taking warfarin, attention must be paid to changes of coagulation profile, especially in elderly patients.

Resistance exercise in the elderly and patients with a cardiovascular disorder has been thought to have a high cardiovascular risk, because it has the tendency to cause an excessive rise in blood pressure and induce serious arrhythmia. But recently, resistance exercise has been introduced into physical therapy because the safety of such exercise has been confirmed in subjects without a cardiovascular disorder.
The purpose of this study was to investigate the safety of lower extremity resistance exercise in middle-aged or elderly subjects with hypertension and receiving medical treatment (n=24), and those without hypertension (n=40), by measuring cardiovascular response during resistance exercise of different loads (40% and 60% 1 RM), and usefulness of respiratory guidance during such exercise.
As a result, there was no difference in diastolic blood pressure between those with and without hypertension ; but systolic blood pressure and rate pressure product both at rest and during exercise were significantly greater in patients with hypertension. However, neither group showed symptoms of angina, ischemic signs in ECG, or serious arrhythmia ; and there was no difference in the frequency of excessive rise in blood pressure between the groups (2 subjects with hypertension and 1 subject without hypertension) . Blood pressure during exercise was significantly lowered by respiratory guidance.
These results show that it is important to measure blood pressure during exercise before resistance exercise training regardless of the presence of hypertension, although an excessive rise in blood pressure occurred in only a few subjects. Furthermore, it is important to exhale slowly and not hold one's breath during exercise.

Although the trunk segment shows well-coordinated movements in concert with the arms and legs during bipedal walking, little is understood about the neural mechanisms controlling the trunk muscles in response to sudden tactile sensations in the foot during walking. This study examined the cutaneous reflexes (CR) to shed light on the neural mechanisms underlying the regulation of the trunk muscles during walking and standing. Eleven healthy men participated in the study. Electromyographic (EMG) activities were recorded in the trapezius (TRAP), erector spinae (ES), and rectus abdominis (RA) muscles. To elicit CR, non-noxious electrical stimulation of the sural nerve at the ipsilateral lateral malleolus was applied during treadmill walking and tonic contraction of the test muscles during standing. During walking, cutaneous nerve stimulation in the foot gave rise to facilitatory CR in all the muscles, and the amplitude of the CR was strongly modulated in a phase-dependent manner. The amplitude of the background EMG and the amplitude of the CR showed a highly significant correlation in all the muscle tested during standing. However, this was true only in the ES during walking. In the RA, the inhibitory CR during standing changed to a facilitatory one during walking. In addition, reflex ratios were significantly larger during walking than standing. These findings suggest that common neural mechanisms in limb muscles could function in the TRAP and RA, however, in the ES disparate neural mechanisms play a crucial role in modulating cutaneous reflexes during walking and standing.

Objective: In this study, the neuroprotective effects of a water-soluble extract from culture medium of Ganoderma lucidum mycelia (WER) on oxidative stress-induced injury were examined using H₂O₂-treated PC12 cells. Additionally, we investigated both the acute and chronic effects of WER on brain necrosis and apoptosis induced by hypoxia/ischemia (H/I) followed by reoxygenation in mice.
Methods: Viability and apoptosis index of H₂O₂-treated PC12 cells were determined by 3,4,5-dimethylthiazol-2-yl (MTT) assay and TUNEL staining, respectively. H/I in mice was induced by unilateral ligation of carotid artery and exposure of 8%O₂ for 30 min. Twenty-four hours after H/I, neurological deficits, cerebral infarction volume, and apoptosis level were evaluated.
Results: WER–pretreated PC12 cells showed an increased viability evaluated by MTT assay compared to untreated cells. TUNEL staining indicated that WER induced a concentration-dependent decrease of the number of apoptotic cells. In the mouse model of H/I, acute (pre-H/I) treatment of WER (1 g/kg, p.o.) did not affect neurological deficits, total plasma oxidative stress, cerebral lipid peroxidation, and infarction volume assessed 24-h after reoxygenation. However, chronic treatment of WER (1 g/kg, p.o., for 7 days) significantly improved these parameters compared with distilled water-treated mice. Moreover, chronic treatment of WER decreased the levels of apoptosis in two brain areas, the sensori-motor cortex and the CA1 of the hippocampus, analyzed by TUNEL and cleaved caspase-3 immunostaining.
Conclusion: These results show that daily intake of WER relieves the cerebral ischemic injury, which may be attributed to decrease of oxidative stress.

Objective: Lentinus edodes (Shiitake) is a very popular mushroom in Asian cuisine. The water-soluble extract from culture medium of Lentinus edodes mycelia (LEM), which is commercially available as a nutritional supplement, is prepared by hot-water treatment from a solid medium composed of bagasse and defatted-rice bran overgrown for about 4 months with its mycelia. LEM was previously reported to have antioxidant activity and to suppress various oxidative damages. In this study, the neuroprotective effects of 2-week intake of LEM on cerebral ischemic damage induced by hypoxia/ischemia (H/I) followed by reoxygenation in mice were examined.
Method: Male C57BL/6J mice were divided into three groups, fed for two weeks with the control laboratory powder chow, 0.5% LEM-contained chow, or 1% LEM-contained chow, respectively. Cerebral ischemic damage was induced in the mice by H/I (i.e., unilateral ligation of the carotid artery and exposure of 8%O₂ for 30 min). Twenty-four hours after H/I, total plasma oxidative stress, neurological deficits, cerebral infarction volume were evaluated in each group. Furthermore, the number of apoptotic cells in ischemic penumbra, the hippocampal CA1 and CA2, and the somatosensory area of the cortex, were analyzed by TUNEL staining and cleaved caspase-3 immunostaining.
Results: The infarct area assessed 24-h after H/I was extended to the corpus striatum and cortex in the control mice. Treatment of LEM dose dependently improved plasma oxidative stress, neurological deficits, and cerebral infarction volume. Moreover, LEM decreased the levels of dihydroethidium activity as an index of super oxide production and the number of apoptotic cells in ischemic penumbra.
Conclusion: These results show that chronic intake of LEM relieves the hypoxia-induced cerebral ischemic injury, which may be attributed to the antioxidant effects of LEM.

This study aimed to evaluate dynamic balance capability, bathyesthesia, and the composite compensation of bathyesthesia and visual sense for dynamic balance assessed by use of force plates and to examine their correlation to age in a cross-sectorial manner. Participants of this study were 147 healthy people (55 men, 92 women). To evaluate dynamic balance capability, we evaluated the index of postural stability (IPS), which is the logarithmic value of the ratio of the area of stability limits to the area of postural sway, with participants standing on a hard surface with eyes opened. To measure bathyesthesia, we evaluated the modified index of postural stability (MIPS), i.e., the IPS with participants standing on a soft surface with eyes closed. As for the composite compensation index of bathyesthesia and visual sense for dynamic balance, we calculated the rubber IPS Romberg ratio (MIPS/IPS). The correlation coefficients (Spearman’s rho) of IPS, MIPS and MIPS/IPS to age were −0.666 (p < 0.001), −0.697 (p < 0.001) and −0.600 (p < 0.001), respectively. These results suggest that dynamic balance capability and bathyesthesia decline with advancing age, and the composite compensation of bathyesthesia and visual sense for dynamic balance strengthens with advancing age.

  After 1985, the decrease in domestic nursing power progressed gradually. The care for the elderly shifted from domestic private nursing to public nursing-care services when the long-term nursing-care insurance law was enacted in 2000. Because many of the elderly receiving nursing care suffer from chronic ailments of hypertension or the consequences of cerebrovascular disease, etc., cooperation between hospitals and nursing homes is necessary and indispensable. We began exchanging information by E-mail on a trial basis with a special elderly nursing home in April 2009. We aimed to integrate medical care and nursing by sharing medical and nursing information. We concluded that the use of E-mail could serve our purpose. The reason why we reached this conclusion is as follows:The mechanism of the information transmission by E-mail, that also relates to semiotics and narratology, is related to the essence of the description. This mechanism functions as a tool for mutual understanding among hospitals, nursing homes, and families. This also functions as a device to make the medical and nursing experience join. As a result, this mechanism enables the elderly to escape death as dying of sickness in the hospital and to die a natural death in the course of nursing. It is an easy method that can be introduced at a low cost for the purpose of establishing cooperation in medical and nursing care among hospitals, clinics, nursing homes, and nursing support centers, etc. especially in medically underserved remote areas.

　　As part of the special study project of the Japanese Association of Rural Medicine (JARM), a questionnaire survey was conducted to probe into the attitude of rural people toward their eating habits and health. Most of the people surveyed had received health checkups carried out by medical facilities affiliated with the JARM.　　Questionnaires were distributed to a total of 5,397 people (2,588 men; 2,809 women) living in and around provincial cities. Mean age was 53.4 for men and 53.8 for women. More than half of those questioned were farmers or had experienced in farming. The people aged 80 and older accounted for 3.2% of the total.　　Eighty percent of the total said they felt happy, and those who felt short of exercise also represented 80%, but with advancing age, the ratio decreased. Those over the age of 70 who said they had a habit of taking exercise made up as high as 60%.　　Many said they were satisfied with food in terms of quantity, but not a few people expressed uneasiness about food safety, dietary life and supply of food. Regarding favorite foodstuffs, many gave rice, vegetables and dairy products. There was a tendency for older people to eat meat less. It was found that, with increasing age, people took to eat dairy products, soybeans, vegetables, fruits and fish were ranked among the most popular foodstuffs.　　A study of factors related to local production for local consumption and commitment to agriculture found that a significantly large number of people were interested in social participation, eating breakfast, securing food supply and purchasing foodstuffs at outlet stores run by local agricultural cooperatives.　　From these findings, it was suggested that many residents in and around provincial cities oriented themselves to healthy eating habits and lifestyle, and were very interested in social participation, local economy, agricultural production and consumption of local farm produce.

We report a patient with unilateral midbrain hemorrhage which caused ipsilateral complete oculomotor nerve palsy with pupillary involvement, contralateral upgaze paresis, contralateral limb ataxia and Parinaud’s syndrome. CT scan and MRI brain demonstrated a hemorrhage in the left paramedian midbrain probably involving the oculomotor fascicles; extension of the hemorrhage to the most rostral midbrain may have involved the pupillary fi bers. It was previously thought that a lesion in the superior colliculus, surrounding nuclei (Darkschewitsch and Cajal nuclei), and the posterior commissure (i.e. dorsal midbrain) were responsible for clinical fi ndings similar to those found in our patient, but our patient showed a hemorrhagic lesion in the left ventral midbrain which did not extend to dorsal midbrain. We propose that the responsible lesion in our patient might involve the rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF).

Background: The palliative care unit (PCU) at the National Cancer Center Hospital East changed the administrative policy to strengthen the transition to palliative home care. This study aimed to identify the factors tended to transfer to palliative home care in Japan. Methods: We reviewed the medical records of consecutive cancer patients admitted to our PCU during period from October 2010 until September 2011. Patients with performance status 4 and duplication were excluded in this study. We identified variables associated with the discharged group and the others group, using the univariate and multivariate analyses. Results: There were 223 patients (Pts) during periods, 63 Pts (28.3%) discharged to palliative home care and 160 Pts (71.7%) deceased in our PCU. Univariate and multivariate analysis identified: admission from their own home, a good PS of ≤ 2, good oxygen saturation, a good amount of oral intake, maintain of PS at day 15, no dyspnea and no abdominal distention as predictions of a transition to home from our PCU. Conclusion: Our study indicated the factors tended to transfer to palliative home care from PCU in Japan, however this study had some limitations. A prospective study is required to validate these factors.
