ABSTRACT
The positive healthy physiological effects of <I>shinrin-yoku </I>in elderly persons were studied. <I>Shinrin-yoku </I>or forest bathing is considered to promote physical relaxation and to have physical and mental health benefits. In this experiment the subjects were elderly 24 male (65.5±2.5years) and 24female (65.0±3.0years) persons who participated in three measurements of <I>shinrin-yoku </I>effects from 2008 to 2010. All the subjects were healthy and volunteered for the experiment. The subjects participated in the <I>shinrin-yoku </I>measurements three times of two hours each on Wednesday in the third week of August in each year. The weather at the time of the three measurements was clear, with temperature of 30°C-32°C, humidity of 58%-60% and wind velocities of 0m/sec-2m/sec. Non-<I>shinrin-yoku </I>measurements were also performed on a different day in an indoor resting environment with the same subjects under the same conditions. For both the <I>shinrin-yoku </I>and non-<I>shinrin-yoku </I>measurements, the subjects were divided into three groups of 8 male and 8 female subjects equally. One was for the visual isolation group in which subjects wore eye masks, another was for the smell isolation group in which subjects wore masks, and the other was the control group in which subjects wore non-isolation material. The concentration of phytoncides in the air was measured using gas chromatography mass spectroscopy. Heart rate (HRs), blood pressure (BP), fasting levels of plasma catecholamine (adrenaline, noradrenalin and dopamine), plasma cortisol and circulating natural killer (NK) cell activity were measured before and after <I>shinrin-yoku</I>. Three kinds of phytoncides derived from trees were detected at the forest-bathing measurement spot in this study. The mean HRs for male subjects under <I>shinrin-yoku </I>and non-shinrin-yoku were 89bpm and 85bpm respectively. The mean HRs for female subjects under <I>shinrin-yoku </I>and non-shinrin-yoku were 86bpm and 85bpm respectively. In the smell isolation group and the control group, systric blood pressure for male and female subjects decreased significantly after <I>shinrin-yoku</I>. In the smell isolation group and the control group, diastolic blood pressure for male subjects decreased significantly after <I>shinrin-yoku</I>.

ABSTRACT
We performed a physio-psychological research on the mental, physical relaxation and health-keeping effect of <i>Shinrin-yoku</i> (forest walking) in Kawaba village. Eleven male and 8 female healthy elderly residents in Kawaba village, whose average age was 74.0±3.5 years old for male and 74.9±2.9 years old for females volunteered for this experiment. All members walked for one hour in the Kawaba Forest on August 17 under cloudy skies, 30-32°C temperature, 58-60% humidity, and, 0-2m/sec wind condition and walked again for another one hour in a non-forest rural agricultural area on August 21 under almost the same weather conditions. Phytoncides in the air, Profile of Mood State (POMS) test, blood pressure (BP), heart rate (HR), fasting levels of serum natural killer cell activity (NK), plasma catecholamine (adrenaline, noradrenalin and dopamine), plasma cortisol, and serum adiponectin were measured before and after walking. Phytoncides were detected in the forest and non-forest, all members showed a decrease of POMS total scale, BP, adrenalin and serum cortisol. Six (3 male and 3 female subjects) of them expressed an increase of serum NK cell activity after the forest-walking. One female showed a high serum NK cell activity after both forest and non-forest rural walking.<br>Our experiment on the forest-walking in Kawaba village indicated that its relaxation and health-keeping effects, probably due to walking in the fresh forest air.
ABSTRACT
It is a big problem to cope with elderly patients who are increasing in a community in Niigata which has already been heavily populated by those people over 65 years of age. Aging is not a disease. However, the actual situation of patients with hematological and solid tumors in the aging community is little known. In this communication, we analyzed 293 patients (AML/ALL: 52, NHL: 112, MDS: 75, MM: 40, and others: 14) and 127 dead with hematological malignancies treated in our hospital for the past 10 years or 80 to clarify the actual changes in the trend of patients with hematological malignancies and compared them with those of patients who died of solid tumors. The population movements over the last 20 years in the Kashiwazaki area were also studied.Our analysis showed that the number of patients who died of solid tumors increased (1.6 times) in step with the increases in the aged population for there 20 years in the Kashiwazaki area. In addition, the incidence of gastric cancer markedly decreased for the past 20 years, while that of colorectal cancer rapidly increased (5 times). The incidence of hematological malignancies also increased with its peak shiftted to the latter haf of the 7th decade of age for the past 10 years. In addition to the increased incidence, patients with NHL and MDS increased in number by 1.5 times over the last 10 years. Especially, patients with MM showed an increase of 3 times, while the incidence of AML was not changed, even decreasing in number.In conclusion, the incidence of hematological malignancies as well as solid tumors has steadily been increasing with the increases in the aged population in the Kashiwazaki area, and the number of the aged patients over 70 years of age also increased. Such aged patients, however, are not available for hematopoietic stem cell transplantation. Therefore, it is urgently necessary for us to cope with the increases in the number of aged patients with hematological malignancies.

It has been known that access recirculation is positively related to dialyzer blood flow and is negatively related to access blood flow in the vascular access in hemodialysis patients. The present study was designed to examine whether an increase in access recirculation generated by an increase in dialyzer blood flow is related to access blood flow. All patients had native end-to-side arteriovenous anastomoses at the radial site. We measured access recirculation at two different dialyzer blood flow rates (85 and 170 ml/min) using a three-needle technique. Access blood flow rates (mean 668 ml/min ranging from 493 to 1038 ml/min) were measured using Doppler ultrasound sonography. We confirmed that an increase in dialyzer blood flow rate led to an increase in access recirculation (5.4±1.1 vs. 9.9±1.9%, p<0.05), and that access recirculation was negatively related to the access blood flow rate (y=-30.78x+972.20, r=-0.79, p<0.05). We further found a negative correlation between the increase in access recirculation generated by the increase in dialyzer blood flow rate and access blood flow rate (y=-33.88x+821.57, r=-0.75, p<0.05). These results suggested that dialyzer blood flow less affects access recirculation when access blood flow is higher.
ABSTRACT
It is considered that hepatitis C virus (HCV) infection may be a pathogenic factor in cryoglobulinemia and glomerulonephritis. The purpose of this study was to determine whether there is any relation between the presence of hepatic disorder due to HCV infection and the association with cryoglobulinemia and urinary abnormalities, i. e. proteinuria and/or hematuria, in HCV-infected patients. Cryoglobulinemia was found in 11.4% of our HCV patients. However, seropositivity of cryoglobulin detected in all the patients was low. The prevalence of the association with cryoglobulinemia in patients with hepatic disorder was significantly higher than that in patients without hepatic disorder. Urinary abnormalities were found in 10.0% of the HCV patients. No significant difference was observed in the prevalence of urinary abnormalities between patients with and without hepatic disorder. In addition, there was no significant difference in the prevalence of urinary abnormalities between the association with and without cryoglobulinemia. These results suggest the close relation between the presence of hepatic disorder due to HCV infection and the association with cryoglobulinemia. However, renal involvement may have no relation with the presence of hepatic disorder and cryoglobulinemia.
ABSTRACT
This report presents our experience in using a dual-lumen catheter with a Dacron cuff as longterm vascular access for homodialysis in an elderly patient. The female patient who at first treated with continuous ambulatory peritoneal dialysis for chronic renal failure, but the treatment could not be continued because she developed inveterate peritonitis. Thereafter, hemodialysis was performed. However, a lot of blood access troubles occurred and consequently peripheral access was exhausted. Therefore, we placed the catheter into a right internal jugular vein. This procedure made it possible to secure enough and stable blood flow during the hemodialysis session. Thus, the clearence ratios of blood urea nitrogen and serum creatinine and the value of KT/V increased. No complications have been observed since then. We further examined whether the placement of the catheter would affect hemodynamics in brain and upper extremities, using transcranial Doppler ultrasound and plethysmography. No remarkable difference in blood flow between right and left ophthalmic arteries and decrease in arterial blood flow of right finger tips were observed. Furthermore, venous dilatation, swelling in neck and right upper extremities, and facial edema were not found. The catheter, therefore, represents a significant advance, providing immediate, durable and relatively safe access for hemodialysis after repeated blood access troubles and exhausted peripheral access.
