The variation of venous concentration of FFA as the effect of exercise under several nutritive conditions were tested on two subjects, i, e., 56 years old male and 20 years old female.
Arrhythmia were recorded when sudden increase in palmitoleic acid in venous concentration was observed, while no arrhythmia were recorded otherwise. Arrtythmia seemed to have been prevented by intaking glucose prior to exercise.
It was also observed that arrhythmia would easily be produced by sudden uprise of palmitoleic acid under hunger after low carbohydrate nutrition.

A 65-year-old patient underwent successful transluminally placed endoluminal prosthetic grafts (TPEGs) of a descending thoracic aortic aneurysm (dTAA). Two hours after TPEGs, the patient suddenly complained of chest, back pain and right leg pain. Angiography and computed tomography showed acute type B aortic dissection. Re-TPEGs was immediately performed, and the entry was successfully closed. This case suggests that TPEGs for the treatment of acute aortic dissection may be useful for selected patients.

The remarkable increase of branched amino acid and pretty decrease of lysine venous concentration were observed in healthy nine male and female adults by the brief fast.
The increase of branched amino acid wasn't able to find by the various exercise generally. The increase of lysine venous concentration was found after the running more than 10km frequently.
Only on the subjects of 44 and 55 years of age, the increase of branched chain amino acid and lysine were observed by the running. It looks like have to take precautions that aged people run under the conditions of empty stomach.

Venous concentration of lysine and other 16 amino acids were determined in healthy 5 male 20-22 years of age subjects in the resting state, after 2 min from bigining of exercise, immediatetly after all-out exercise and 30 min after of the exercise with a bicycle ergometer at work intensities which will be fell into all-out in about 6 or 7 min.
During 2 min exercise lysine only was increased, no change of glycine and puoline were observed and other amino acids were decreased. At the point of all out increase of threonine, lysine and histidine were observed, compared with resting state
Alanine concentration at 30 min after of all out exercise was very high than that of resting state and same tendency but a little was observed on lysine. Other amino acids were decreased.
A risk connected with exercise was discussed from the data of lysine obserbed high concentration during two min exercise concerning with the variation of other amino acids by the all-out exercise.

The present study was performed to investigate the effect of long distance walking upon physical functions for healthy male subjects. The first experiment was carried out in 1977, the second, in 1978, and the third, in 1979 in each autum season. At the first experiment, subjects began walking upon having breakfast, then ate and drank noting during first 30km, and took some foods during another 26km. Twelve hours and fifty minutes of time was spent for 56km walking including 15, 60, and 30 minutes rest periods in between. In the second experiment, subjects ate nothing after dinner of the previous evening and 35km walking took 6 hours during which some rest periods were taken for blood sampling. The third was 80km walking for two days. Subjects walked 40km in 8 hours in the first day and on the following day they walked 40km in ten hours and twenty minutes. They took foods and rest freely.
From the view points of the changes in blood and urinary recordings obtained from those three experiments, the influences of long distance walking on the body indicate as follows ;
1) In case of long distance walking while nothing to eat and drink, the rate of serum saturated fatty acids composition decreased and unsaturated fatty acids increased.
2) In a fasting state, blood glucose gradually decreased, LDH activity increased and blood lactate, GOT and GPT activity presented no significant changes on long distance walking.
3) It was shown that the longer distance to walk, the lesser tendency in blood triglyceride even though subjects take a carbohydrate rich diet while walking.
4) In fasting state, less than 35km walking without foods, the stress to the body seemed not to be critical.
5) More than 40km walking in a day, even though taking meals, would result a significantly severe stress for body.
6) As long as usual meals are taken, 80km walking for two days continuously, 40km in each day, would not result in such a physical stress over the following days.

Hyperbaric oxygen (HBO) therapy for acute carbon monoxide (CO) poisoning is performed after oxygen therapy and breathing therapy. The usefulness of HBO therapy in emergency treatment has been reported. In this study, we examined the effectiveness of HBO for CO poisoning that was performed at our hospital over the past 5 years. Subjects were 23 patients who had HBO therapy for CO poisoning in the period January 2008-November 2013. The male to female ratio of the cases was 14:9 and the mean age was 54.6±20.8 years. The cause was suicide in 39.1% of cases and accident in 60.9%. The mean number of treatments was 5.4±6.8. The atmosphere absolute was 2ATA:2.8ATA=12:11. The ratio of direct conveyance of the patient to our hospital to indirect conveyance of the patient from another hospital was 15:8. The effectiveness of HBO therapy at the time of discharge was 73.9%. However, delayed neuropsychiatric sequelae (DNS) was detected in 3 of the 23 cases of CO poisoning. No correlations were found between elapsed time after CO inhalation and various blood parameters. However, time to start of therapy is important for DNS, and our results suggest that early treatment at a hospital with a hyperbaric chamber is necessary.

The anti-obesity effects of a hot water extract from wasabi (Wasabia japonica Matsum.) leaves (WLE), without its specific pungent constituents, such as allyl-isothiocyanate, were investigated in high fat-diet induced mice. C57J/BL mice were fed a high-fat diet (control group) or a high-fat diet supplemented with 5% WLE (WLE group). Physical parameters and blood profiles were determined. Gene expression associated with lipid metabolism in liver and white adipose tissue were analyzed. After 120 days of feeding, significantly lower body weight gain, liver weight and epididymal white adipose tissue weight was observed in the WLE group compared to the control group. In liver gene expression within the WLE group, PPARalpha was significantly enhanced and SREBP-1c was significantly suppressed. Subsequent downstream genes controlled by these regulators were significantly suppressed. In epididymal white adipose tissue of the WLE group, expression of leptin, PPARgamma, and C/EBPalpha were significantly suppressed and adiponectin was significantly enhanced. Acox, related to fatty acid oxidization in adipocytes, was also enhanced. Our results demonstrate that the WLE dietary supplement induces mild suppression of obesity in a high-fat diet induced mice, possibly due to suppression of lipid accumulation in liver and white adipose tissue.

BACKGROUND/AIMS: Helicobacter pylori infection causes gastritis, peptic ulcers and gastric malignancies, and its eradication has been advocated by many groups. We determined the H. pylori carrier status and eradication rates of patients with chronic hepatitis C virus (HCV) infection. METHODS: In total, 76 chronically HCV-infected patients were enrolled for comparison with 228 HCV-noninfected, age- and sex-matched controls. H. pylori infection was confirmed by H. pylori antibody and urea breath testing. RESULTS: The H. pylori infection rate was significantly higher for HCV-infected patients (67 of 76, 88.2%) than for HCV-noninfected controls (158 of 228, 69.3%). Endoscopic findings showed that the rates of gastric ulcers and gastritis were significantly higher for the 67 HCV-infected patients with H. pylori infection (34.3% and 77.6%) than for the 158 HCV-noninfected controls with H. pylori infection (15.2% and 57.6%). Treatment to eradicate H. pylori had a significantly higher success rate for HCV-infected patients (61 of 67, 91.0%) than for HCV-noninfected controls (115 of 158, 72.8%). CONCLUSIONS: The markedly high H. pylori eradication rate observed in this study shows that eradication of H. pylori holds promise for the improvement of the long-term health condition of patients with chronic HCV infection.

Background/Aims:
Patients with acute cholecystitis (AC) after metallic stent (MS) placement for malignant biliary obstruction (MBO) have a high surgical risk. We performed percutaneous transhepatic gallbladder aspiration (PTGBA) as the first treatment for AC. We aimed to identify the risk factors for AC after MS placement and the poor response factors of PTGBA.
Methods:
We enrolled 401 patients who underwent MS placement for MBO between April 2011 and March 2020. The incidence of AC was 10.7%. Of these 43 patients, 37 underwent PTGBA as the first treatment. The patients’ responses to PTGBA were divided into good and poor response groups.
Results:
There were 20 patients in good response group and 17 patients in poor response group. Risk factors for cholecystitis after MS placement included cystic duct obstruction (p<0.001) and covered MS (p<0.001). Cystic duct obstruction (p=0.003) and uncovered MS (p=0.011) demonstrated significantly poor responses to PTGBA. Cystic duct obstruction is a risk factor for cholecystitis and poor response factor for PTGBA, whereas covered MS is a risk factor for cholecystitis and an uncovered MS is a poor response factor of PTGBA for cholecystitis.
Conclusions
The onset and poor response factors of AC after MS placement were different between covered and uncovered MS. PTGBA can be a viable option for AC after MS placement, especially in patients with covered MS.
