The muscle glycogen is an important energy source for muscle contraction especially in prolonged exercise. One of the important factors for improvement of physical performance in athletes is the storage of extra-amount of glycogen (supercompensation) in liver and muscles. During 120 minutes treadmill exercise (intensity of exercise was approximatly 80% VO2max), the glycogen concentration was significantly decreased to 36% in liver and 46% in muscles after 60 minutes exercise. At 90 and 120 minutes of exercise, the level of glycogen concentration of liver and muscles statistically were not different from the levels of the 60 minutes exercise. The repletions of glycogen in the liver and muscles in overnight fasted control(C) and 120 minutes treadmill exercise(E) groups during l80minutes after glucose ingestion were investigatect. ln the liver, the concentration of glycogen in C and E groups were markdly increased till 120 minutes after zlucose ingestion, hut the levels of concentration at 180 minutes were decreased comparing to the levels of 120 minutes in both groups. In the muscles, the repletion of glycogen at 60, 120 and 180 minutes of C and E groups were significantly increased comparing to 0 minute of respective groups in the soleus and plantaris muscles. In soleus(SOL), the repletion of glycogen in all of the E groups was significantly higher than that of the respective C groups. However, the repletion of glycogen in all of the E groups of plantaris was revealed higher tendency comparing to respective C groups. Mean repletion rates of glycogen in liver and muscles after glucose ingestion were highest during the first 60 minutes in all groups and the rates of E groups were 2-3 times than those of respective C groups. These results suggest that the glycogen supercompensation in the muscle be provided with decrement of glycogen concentration by exercise, increment of glucose uptake by muscuiar contraction itself and increased insuJin level, and the activation of glycogen synthetase by insulin.

BACKGROUND: Since the bioavailability of itraconazole capsule is influenced by patients gastric acidity, it results in treatment failure due to its low dissolution and subsequent low absorption when administered in fasting. Itraconazole Melt-Extrusion tablet has been lately developed in order to improve its dissolution profile. It is the first clinical study to evaluate the efficacy and safety of itraconazole Melt-Extrusion tablet in Korea. OBJECTIVE: This study was conducted to evaluate the efficacy and safety of itraconazole melt-extrusion tablet 400mg daily for 1 week(pulse therapy) for hyperkeratotic type of tinea pedis and manus. METHODS: A clinical and mycological investigation was made of 812 outpatients with hyperkeratotic type of tinea pedis and/or tinea manus who had visited at 52 general hospitals under the lead of the Korean Dermatological Association from June to December, 1998. Patients confirmed by clinically and microscopically as hyperkeratotic type of tinea pedis and/or tinea manus were administered 2 tablets twice a day for one week and followed up for 8 weeks from the start of the medication. RESULTS: The results were summarized as follows; 1. Clinical symptoms of hyperkeratotic type of tinea pedis and/or tinea mauns were significantly improved at the end of study, week 8(p<0.001). 2. Clinical response rate, defined as more than 50% decrease of the sum of the clinical symptom scores, was 79.3%(512/646). 3. Mycological cure rate, dafined as both culture and KOH negative at week 8, was 78.2%(244 /312). 4. 40(5.5%) patients, of the 727 patients evaluable for drug safety evaluation, were reported to have adverse event. CONCLUSION: Itraconazole Melt-Extrusion tablet 400mg/day for 1 week (pulse therapy) is effective and safe in the treatment of hyperkeratotic type of tinea pedis and/or tinea manus.
