This study was designed to investigate the effects of Kyungohkgo to improve aerobic capacity and eliminate exercise-induced fatigue in high school soccer players. Twenty four subjects were participated and randomly assigned into two groups [KG, Kyungohkgo group (n=12); PG, Placebo control group (n=12)]. Two groups were completed treadmill exercise protocol using graded exercise test at before and after experimental treatment of 4 weeks. The $VO_2$max and endurance time were measured by gas analysis and heart rate (HR) was measured by polar system at pre, post 0, post 5, post 15, post 30 and post 60 minutes. Blood samples were collected to analyze blood components. 1. The $VO_2$max was significant increased in the group of after intake Kyungohkgo compared to the group of after intake placebo (p<.05). 2. The HR was significant decreased in the group of after intake Kyungohkgo compared to the group of after intake placebo during recovery time at post 5 mins(p<.05), 30 mins(p<.01), 60 mins(p<.01). 3. Weight, body mass index, percent body fat, anaerobic threshold, endurance time, blood lactate concentrate, lactate dyhydrogenase, creatine kinase, serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, other energy sources(total-cholesterol, triglyceride, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol, creatinine) and electrolyte (Na, K, Cl) were shown no significant differences between groups. These results suggested that Kyungohkgo can be used as ergogenic aids to improve aerobic capacity and eliminate exercise-induced fatigue.

Purpose: This study was conducted to investigate the muscle anti-fatigue effects of Morindae officinalis Radix liquid extract. Methods: 4-6 weeks old ICR rats are used in the study, and we administered the extracts powder of Morinda officinalis concentration of 1, 10, 100mg/0.3 ml to each to rats(MO group) once a day for each 30 and 60 days. After 30 and 60 days, we examined the plasma concentraion of lactate dehydrogenase, glucose. And we measured the persistent time of swimming exercise test and conducted grip strength test Results: We found that there are no significantly differences between the control and the treatment group in the plasma concentration of activity level of lactate dehydrogenase. And we found that in 30days group, level of glucose concentration is significant. In swimming exercise test, as administration time and concetration growed up, swimming time is increased. And in grip strength test, as concentraion is growed up, grip strength is increased. Conclusion: This study show that Morinda officinalis is effective against muscle fatigue.

Objectives: Hepatitis A is a typical acute hepatitis caused by hepatovirus, and then most patients recover easily without progression to chronic condition. However, certain cases have the risk of severe symptoms or even death. This case report presented a hepatitis A accompanied with pancreatitis, which had been completely recovered in a Korean medicine hospital. Case presentation: A 38-year woman had felt the malaise, mild chilling, muscle pain and abdominal discomfort for 10 days, which led her visit doctors and took anti-pyretic analgesics and digestants. The symptoms, especially epigastric pain and fatigue, became worse, and then she hospitalized in a Korean medicine hospital. Based on the drastic elevations of hepatic enzymes (aspartate transaminase 1,604 IU/L and alanine transaminase 2,825IU/L) with an anti-HAV IgM positive, she was diagnosed with hepatitis A. After bed rest and herbal drug treatment (CGX and Innae-Tang) for 5 days, the laboratory abnormalities and subjective symptoms had been improved gradually, except the upper gastric discomfort and pain. Those symptoms had anticipated the comorbidity with HAV-induced pancreatitis, supported by the high level of serum lipase release. Another 5-day hospitalized treatment improved all subjective symptoms and then the laboratory results were completely normalized including detection of anti-HAV IgG within 15 days after discharge. Conclusion: This study presented a typical hepatitis A accompanied with pancreatitis, which should be considered in diagnosis and management of hepatitis A.

In this study, the wedge splitting tcst (WST) was carried out for the fatigue wack growth behavior of concrete. Selected test variables were concrete compressive strength of 28, 60 and 118 MI%, and stress ratio with 2 levels (6. 13%). In oder to make the designed stress ratio, the maximum and thr minimum fatigue loading level were 75-85% and 5- 10% of ultimate static load, respectively. Fatigue testing was preceded by crack mout.h opening displacement (CMOI)) compliance calibration tcst, and then the fatigue crack growth was computed by crack lcngth vs. (lMOI) compliance relations acquisited by the CMOD compliance calibration technique. To evaluate thc validity of CMOD compliancc calibration techniquc, the crack length p~mlicted by this method was cornpard with the crack length by linear elastic fracture mechanics(LEFIbl) and dyeing test. On the basis of the experimental results, a LRFhl-based c.mpirica1 model for f'at,igue crack growth rate(da/dN-AKI relationships) was presented. The fat,igut. crack growth ratc increased with the strength of concwtc. It appcars that t.he da/tiN-AKI relationships was influenced by stress ratio, however, the effect is diminished with an increase of strength. The comparisons between CblOl) compliance calibration technique anti the other. methods gave the validity of' ('MOD compliance calibration technique for the LZXT.
