 Acupuncture treatment is one of the conditioning methods in the competition field. Athletes who are forced in regularly intensive training often induced deteriorating of condition. Good conditions are adjusted by interaction of immune system, nervous system and endocrine system. Neutrophils and lymphocytes which are blood components prevent infections of the human body in various ways. Intensive training causes an increase of neutrophils, a decrease of lymphocytes and a negative impact on the immune functions. It has been reported that acupuncture stimulation could be involved in the coordination of the immune system. Therefore, acupuncture treatment could be important to keep physical condition and participate physical activity according to the plan without deteriorating of condition. It may be useful not only for athletes but also for the general public who train for the purpose of health and sports enthusiasts. The purpose of this study was to examine the effect of acupuncture stimulation on fluctuation of neutrophils and lymphocytes by the transient high-intensity exercise.
Method : Twelve healthy men (23.6±O.3 yr [±SE]) participated in this study. Subjects exercised on bicycle ergometer for 60 minutes at 75% of their VO₂max. Acupuncture treatment was applied at LU6 (Kongzui), LI 4 (Hegu), ST 36 (Zusanli), and ST 6 (Jiache), for 30 min after the exercise. Blood samples were taken before exercise, immediately after exercise, hourly after exercise until 4 hours and 24 hours after exercise. Leukocyte, neutrophils, lymphocytes, Th cells and Tc cells were measured from the blood samples.
Result : The neutrophils significantly increased from Post 1h to Post 4h in the both trials (P < 0.05). However the neutrophils was significantly lower in the acupuncture group than in the control group at Post 1h and Post 3h (P < 0.05). The lymphocytes significantly increased from immediately after exercise to Post 24h in the control trial, and increased significantly only at Post 1h to Post 3h in the acupuncture trail (P<0.05). The Th cells significantly decreased from Post 1h to Post 24h in the control trial and decreased significantly only at Post 1h, 2h and 24h in the acupuncture trail (P < 0.05).
Conclusion : These results suggested that acupuncture stimulation may reduce the increase of neutrophils and the decrease of lymphocyte and Th cells caused by high-intensity exercise. These results indicated that acupuncture stimulation may promote the recovery from high-intensity exercise.

Objective: The purpose of this study was to examine the effects of Coenzyme Q10 (CoQ10) supplementation on salivary secretory immunoglobulin A (SIgA) and health-related Quality of Life (QOL) in middle-aged and elderly individuals. Methods: Sixty healthy middle-aged and elderly individuals were assigned randomly to a CoQ10 supplementation group (n = 30) or a placebo supplementation group (n = 30) using a double blind method. Subjects took 150 mg CoQ10 or placebo per day for 8 weeks. Salivary SIgA secretion rate and SF-36 test (physical and mental health-related QOL) were determined before and after the intervention. Results: CoQ10 group showed that a tendency to increase of salivary SIgA secretion rate (p = 0.08), although placebo group did not show significant change. Physical health-related QOL did not significantly change in both groups. Vitality and mental health scores, which were subscale of mental health-related QOL, were significantly increased after the intervention in CoQ10 group (p < 0.05), although placebo group did not show significant change. Conclusion: 8 weeks of CoQ10 supplementation may bolster SIgA-mediated oral immunity and mental health-related QOL in middle-aged and elderly individuals.

The purpose of this study was to investigate the relation between alterations of salivary secretory immunoglobulin A (SIgA) and the occurrence of upper respiratory tract infections (URTI) in rugby football players.We examined the relationship between the onset of URTI and the daily alterations of SIgA levels in 32 male collegiate rugby football players (20.5±1.3 years) during summer training camp for 36 days.Total of 6 in 32 subjects had the appearance of URTI symptoms (18 %). SIgA secretion rate decreased significantly in the middle of training camp compared to the baseline (P＜0.05). Furthermore, SIgA secretion rate during the appearance of URTI (13.7±1.1μg/min) were significantly lower than that without symptoms (19.2±1.4 μg/min, P＜0.01). These results suggest that serial monitoring of SIgA may be useful to assess the risk status of URTI affection in athletes.

The purpose of this study was to investigate the effects of Lactobacillus gasseri OLL2809 (MG2809) intake on salivary secretory immunoglobulin A (SIgA) secretion and incidence of upper-respiratory tract infection (URTI) symptoms among college rugby athletes. Sixty-seven subjects were assigned to a MG2809 group (n = 33) or a placebo group (n = 34) using a double-blind procedure. Each subject took MG2809 or placebo tablets for 9 weeks. Resting saliva samples were collected before (0 week) and after 2, 4, 6, 8, and 9 weeks of the MG2809 intakes. A log of URTI symptoms was kept every day during the study period. Our results showed that salivary SIgA level was significantly increased at 6 weeks in the MG2809 group (p < 0.05), although the placebo group did not show significant change. The duration of URTI symptoms episode in the MG2809 group was significantly shorter than that in the placebo (p < 0.05). These results suggest that regular intake of MG2809 may enhance oral immune function mediated by SIgA and reduce the risk of URTI in athletes.

A 61-year-old man was found to have an abdominal aortic aneurysm (AAA) during follow-up for ischemic heart disease. On admission, ultrasonograms and computed tomograms revealed a thickened aortic wall surrounded by a soft tissue (so-called mantle). The obstructive right anterior brain artery and stenotic right internal carotid artery were also detected by angiography. Coronary angiography demonstrated multiple stenotic lesions of the coronary arteries. The excised AAA was replaced with an prosthetic graft. The mobilization of the adjacent viscera was kept as little as possible in order to prevent injury to them. We reported a case of “inflammatory” abdominal aneurysm associated with various atherosclerotic lesions.

Myxopapillary ependymoma in childhood typically occurs in the central nervous system. There are few surgical cases of myxopapillary ependymoma of the cauda equina in children. We report a case of myxopapillary ependymoma of the cauda equina in a 5-year-old boy, who presented with leg pain and abnormal gait. Subtotal resection surgery was performed. Following the subtotal tumor resection, follow-up magnetic resonance imaging evaluation showed a recurrent tumor. As a result, we performed a second subtotal tumor resection and followed with postoperative radiation therapy. No further evidence of the disease has been noted elsewhere in the patient in over ten years of follow-up. Myxopapillary ependymoma of the cauda equina in a young boy was improved by subtotal tumor resection and postoperative radiation therapy.

People in tropics have the ability to tolerate heat by residential permanence in the tropics. Previously, we have shown that African and Thai subjects who lived for whole their lives in only their respective countries sweat less under hot conditions than South Koreans who also lived whole their lives in Korea. The difference in sweating responses was attributed to the dissimilar central and peripheral sweating mechanisms operating in people from both groups. In the present study, acetylcholine (ACh), the primary transmitter for the sudomotor functions, was iontophoretically administered to South Koreans and Africans to determine the characteristic sudorific responses of their acclimatized biologic make-up to their respective environments. Using quantitative sudomotor axon reflex test (QSART), direct (DIR) and axon reflex (AXR) responses were evaluated. The findings revealed that the sweat onset-time among South Koreans was 0.91 min earlier than among Africans (P< 0.01). The axon reflex sweat volume of nicotine receptor activity AXR (1) and sweat volume of muscarinic receptor activity DIR (2) among South Koreans were 79% and 53% greater (P< 0.01), respectively. These results indicate that the reduced thermal sweating among Africans is at least in part attributed to the diminished sensitivity of sweat glands to ACh.

Methods: A retrospective multicenter study was conducted. The study participants included 345 patients who underwent surgery for spinal metastases from 2010 to 2020 at nine referral spine centers in Japan. Data for each patient were extracted from medical records. To identify the factors predicting survival prognosis after surgery, univariate analyses were performed using a Cox proportional hazards model. Results: The mean age was 65.9 years. Common primary tumors were lung (n=72), prostate (n=61), and breast (n=39), and 67.8% (n=234) presented with osteolytic lesions. The epidural spinal cord compression scale score 2 or 3 was recognized in 79.0% (n=271). Frankel grade A paralysis accounted for 1.4% (n=5), and 73.3% (n=253) were categorized as intermediate or high risk according to the new Katagiri score. The overall survival rates were -71.0% at 6 months, 57.4% at 12, and 43.3% at 24. In the univariate analysis, Frankel grade A (hazard ratio [HR], 3.59; 95% confidence interval [CI], 1.23–10.50; p<0.05), intermediate risk (HR, 3.34; 95% CI, 2.10–5.32; p<0.01), and high risk (HR, 7.77; 95% CI, 4.72–12.8; p<0.01) in the new Katagiri score were significantly associated with poor survival. On the contrary, postoperative chemotherapy (HR, 0.23; 95% CI, 0.15–0.36; p<0.01), radiation therapy (HR, 0.43; 95% CI, 0.26–0.70; p<0.01), and both adjuvant therapy (HR, 0.21; 95% CI, 0.14–0.32; p<0.01) were suggested to improve survival. Conclusions Surgical indications for patients with Frankel grade A or intermediate or high risk in the new Katagiri score should be carefully considered because of poor survival. Chemotherapy or radiation therapy should be considered after surgery for better survival.

OBJECTIVETeeth can serve as records of environmental exposure to heavy metals during their formation. We applied a new technology - synchrotron radiation microbeams (SRXRF) - for analysis of heavy metals in human permanent teeth in modern and historical samples.

METHODSEach tooth was cut in half. A longitudinal section 200 mum in thickness was subjected to the determination of the heavy metal content by SRXRF or conventional analytical methods (ICP-MS analysis or reduction-aeration atomic absorption spectrometry). The relative concentrations of Pb, Hg, Cu and Zn measured by SRXRF were translated in concentrations (in g of heavy metal/g of enamel) using calibration curves by the two analytical methods.

RESULTSConcentrations in teeth in the modern females (n = 5) were 1.2 +/- 0.5 mug/g (n = 5) for Pb; 1.7 +/- 0.2 ng/g for Hg; 0.9 +/- 1.1 mug/g for Cu; 150 +/- 24.6 mug/g for Zn. The levels of Pb were highest in the teeth samples obtained from the humans of the Edo era (1603-1868 AD: ) (0.5-4.0 mug/g, n = 4). No trend was observed in this study in the Hg content in teeth during 3,000 years. The concentrations of Cu were highest in teeth of two medieval craftsmen (57.0 and 220 mug/g). The levels of Zn were higher in modern subjects (P < 0.05) than those in the Jomon (~1000 BC: ) to Edo periods [113.2 +/- 27.4 (mug/g, n = 11)]. Reconstruction of developmental exposure history to lead in a famous court painter of the Edo period (18th century) revealed high levels of Pb (7.1-22.0 mug/g) in his childhood.

CONCLUSIONSSRXRF is useful a method for reconstructing human exposures in very long trends.
