The purpose of this study was to know the effect of short termed fasting on the usage of metabolic energy sources and the metabolic differences between non-athletic and athletic subjects. Subjects were divided into non-athletic and athletic group and exercise was loaded on both groups after feeding and fasting. Exercise was loaded by a treadmill running at the speed of 8 km/hour for 30 minutes in both groups. The experiment yielded following results. In the fed state, the level of plasma FFA increased markedly after 15 and 30 minutes of exercise compared with it's level of pre-exercise period in both groups. In the fated state, the level of plasma FFA in non-athletic group increased steadily according to the duration of exercise, while it's level in athletic group showed no changes. At pre-exercise period, the level of plasma FFA was higher in fasted state than fed state. Immediately before the exercise and 15 and 30 minutes after the exercise, blood for the determination of plasma free fatty acid (FFA), glucose, triglyceride (TG) and cholesterol was sampled from antecubital vein, and simultaneously heart rate was measured. In the fed state, the level of plasma glucose was increased mildly according to exercise, and in the fasted state it's level increased according to exercise in both groups also. In the fasted state, the level of plasma TG was lower than that in the fed state. The level of plasma TG and cholesterol in the fed state was no changed by the exercise from the pre-exercise period. The level of plasma cholesterol in athletic group had tendency to lower than that in non-athletic group. Heart rate increased markedly according to exercise in both groups, but the athletic group's increasing rate of heart rate was lower than the non-athletic group's heart rate increased according to exercise and athletic groups heart rate increased early period of exercise, but did not change during latest post-period of exercise.

This investigation was undertaken to clarify the in vitro effect of the various stimulations, such as exercise (E), insulin (I) direct electrical stimulation (EST) and the combinations of the above, on the glucose incorporation intro glycogen molecules (glycogen synthesis) of the normal slow (soleus) and fast twitch (plantaris) muscles, and the different responses of slow and fast twitch muscles to persistent overloads causing compensatory muscle hypertrophy. In resting state, slow twitch muscle has greater capacity for glycogen synthesis than fast twitch muscle, and responses of different muscle to various stimuli were differ as follows: In slow twitch muscle, the glycogen synthesis was increased by insulin, and electrical stimulation but not increased by exercise; exercise increased insulin sensitivity and the effect of electrical stimulation. Whereas the glycogen synthesis in fast twitch muscle was increased only by the stimuli combined with E and EST, and E, I, and EST. As the result of removal of synergistic muscle, both muscles were hypertrophied, and the degree of hypertrophy in response to persistent overload was higher in fast twitch muscle (182%) than slow twitch muscle (151%). In hypertrophied muscles, glycogen synthesis of soleus in any groups was lower than that of the control, but similar in plantaris. In conclusions, there were marked heterogeneity in different muscle fiber in the effects of exercise and insulin addition and electrical stimulation on muscle glycogen synthesis, and fast twitch muscle may be adapted more easily to that kind of persistent overload than slow twitch muscle.

This study was conducted to evaluate the association of job characteristics and stress indicators, from May 1st to 10th, 1996. The study population was 210 workers (clerical workers, 67; engineers, 82; assembly line workers, 61) engaged in a television manufacturing company. A questionnaire method was used to collect the data regarding to job demand, job control, behavioral type, life style and psychiatric symptoms. Clinical examination was conducted to measure blood pressure, serum cholesterol, fasting blood sugar and HbA1c. Percentage of high subjective job strain group was significantly higher in clerical workers(9.0 %) than in engineers(4.9 %) and in assembly line workers(3.3 %) (p < 0.01). Mean values of fasting blood sugar and HbA1c were significantly different between types of occupation and were the highest in clerical workers (p < 0.05). Significant association was found between perceived job characteristics and psychiatric symptom score (p < 0.01). The more job demand and the less job control was, the higher psychiatric symptom score was reported. Diastolic blood pressure was significantly related to job control (p < 0.05). The more job control was, the higher blood pressure was reported. In multiple regression analysis, job demand, job control and age were significant variables explaining the psychiatric symptoms and R2 was 0.23. Perceived job characteristics and type of occupation were not significant in explaining diastolic blood pressure and cholesterol. Type of occupation, job demand, age and BMI were significant variables explaining lasting blood sugar and R2 was 0.25. Type of occupation was the only significant variable explaining HbA1c and R2 was 0.07. According to this result, occupational type and subjective job characteristics must be considered in study of job stress. As a result of multiple analysis, subjective job characterics are significantly related to psychiatric symptoms and type of occupation is significantly related to fasting blood sugar and HbA1c.

Better palliative management of patients with disseminated cancer has prolonged their lives but has raised the incidence of pathologic fractures in their variable lives. The essence of treatment is to prolong life, maintain comfort, and stabilize the patient with metastatic disease. The treatment of pathologic fractures with internal fixation has long been accepted by orthopedic surgeons and the benefits afforded to the patient are well known, so adequate fixation is essential. A combination of methylmethacrylate and internal fixation devices can greatly enhance the stability of fixation, because diseased bone is a poor base on which to insert an internal fixation device. The authors have treated 19 cases of the pathologic fracture of spine, humerus and femur by use of bone cement with and without internal fixation devices. The results are as follwed. 1. All cases utilized methylmethacrylate and there was no complication in methylmethacrylate in itself. 2. All cases had received various type of ancillary treatment: radiation in 9 cases, chemotherapy in 4 cases and in 8 cases, conservative pain control. 3. In spinal pathologic fracture with paraplegia or neurologic deficiency, the patients could walk with walker at an average of two weeks after operation. 4. Among the 19 cases, the pain was relieved markedly and ambulation was possible easily and early after operation in 16 cases. 5. Among the 19 cases, two survived less than 2 months, 7 surrived from 2 month to 3 month, five survived from 3 months to 6 months, four survived from 6 months to a year and one survived more than a year.

Peripheral arterial disease(PAD) is a major health problem in the elderly population, so prevalence of PAD is investigated using Edinburgh claudication questionnaire. Subjects were over 65 years old in the kyeongsan county. The prevalence of PAD was 9.0% in total population(8.5% in men, 9.3% in women). definite claudication was 3.9%, atypical claudication was 5.l%. and, grade 1 was 4.4%, grade 2 was 4.6%. The prevalence of PAD was increased with age but not statistically significant. There was no difference of PAD by gender and smoking. PAD was significantly associated with systolic blood pressure positively. But, unexpectedly, PAD was significantly associated with BMl negatively. PAD are important elderly health problem in the our country. so the etiology and preventive methods of PAD will be researched on our country population.

PURPOSE: To evaluate the association between age and peripapillary retinal nerve fiber layer (RNFL) thickness measured by Cirrus high-definition (HD) spectral domain optical coherence tomography (OCT) in healthy Korean subjects. METHODS: A total of 302 eyes from 155 healthy Korean subjects (age range, 20 to 79 years) underwent RNFL thickness measurements using the Cirrus HD-OCT. Average, quadrant, and clock-hour RNFL thickness parameters were analyzed in terms of age using linear mixed effect models. RESULTS: Average RNFL demonstrated a slope of -2.1 microm per decade of age (p < 0.001). In quadrant analysis, superior (-3.4 microm/decade, p < 0.001) and inferior (-2.9 microm/decade, p < 0.001) quadrants showed steeper slopes, whereas temporal (-1.1 microm/decade, p < 0.001) and nasal (-1.0 microm/decade, p < 0.001) quadrants revealed shallower slopes. Among the 12 clock-hour sectors, clock hours 6 (-4.5 microm/decade, p < 0.001) and 1 (-4.1 microm/decade, p < 0.001) showed the greatest tendency to decline with age; RNFLs of the 3 (-0.2 microm/decade, p = 0.391) and 4 (-0.6 microm/decade, p = 0.052) o'clock hour sectors did not show significant decay. CONCLUSIONS: RNFL thickness was associated with age, especially in superior and inferior areas. The topographic distribution of correlation between age and RNFL thickness was not uniform.
