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.

Fanconi syndrome is a complex of renal tubular dysfunction defined by glycosuria without diabetes, generalized aminoaciduria, phosphaturia, bicarbonaturia, uric aciduria, and renal tubular acidosis. It is often associated with hypokalemia, hypophosphatemia, rickets and osteomalacia. We have experienced one case of Fanconi syndrome with chronic tubulointerstitial nephritis. The patient was a 4 year old and his chief complaints were polyuria, polydipsia, and poor weight gain. There were hyperchloremic metabolic acidosis, hypokalemia, glycosuria, generalized aminoaciduria and phosphaturia. We report a case of Fanconi syndrome with brief review of the literatures.

PURPOSE: This study examined the effects of fast walking training on a treadmill on the spinal alignment and muscle thickness of normal adults. METHODS: A total of 36 college students in their twenties participated in the study for eight weeks, and they were divided into the normal walking, fast walking, and speed change groups. All the groups were measured in a pre-test before training. The subjects performed exercise three times per week for six weeks. A post-test was conducted six weeks after training began, and a follow-up test was done two weeks after the training ended.Trunk and pelvic tilts were measured in Formetric 4D for the spinal alignment of the subjects. The muscle thickness was examined in the trunk with an ultrasound test. Repeated-measures ANOVA was conducted to test the main effects and interactions among the measurement variables according to time and group. RESULTS: ignificant differences were observed in the pelvic tilt according to time. There were significant differences in the external oblique, internal oblique, transverse abdominal muscle according to time. The post-test results showed significant differences in the left external oblique, internal oblique muscles between before training, six weeks into training, and two weeks after the completion of training. There were significant interactions in the left oblique muscles according to the time and group. CONCLUSION: These findings have some value for patient rehabilitation and clinical applications and interventions through walking training.

PURPOSE: Leptin is a highly hydrophobic 16-kDa protein encoded by the ob gene which is expre- ssed in adipocytes and participates in the regulation of food intake and energy expenditure. The aims of the present study were to examine the comparison of leptin levels between type I diabetes mellitus (DM) patients who received exogenous insulin therapy and healthy children, and to find out correlating factors with leptin level in type I DM. METHODS: The study was conducted on 34 patients with type I DM and 29 healthy children. Body weight, height, leptin level and body fat percent were measured in both groups. The glycosylated hemoglobin value, C-peptide, insulin level and serum cholesterol were also measured in type I DM. RESULTS: There was no statistically significant difference in mean age, sex distribution and body mass index between the experimental groups, but body fat percent in type I DM was significantly lower than that of healthy children. The mean leptin levels in male (9.4+/-6.3ng/mL) and female (17.8+/-10.2ng/mL) type I DM were significantly higher than in male(6.3+/-5.7ng/mL) and female (10.2+/-0.9ng/mL) healthy children (male : P=0.045, female : P=0.005). Serum leptin levels were strongly correlated with the body fat percent (Pearson coefficient) (r=0.712). CONCLUSION: Serum leptin level in type I DM strongly correlated with the body fat percent. Despite lowered body fat percent in type I DM, the leptin level was significantly higher than values in healthy children. The mean leptin level in type I DM were significantly higher than value in healthy children, but body fat percent of type I DM was lower than value in healthy children who were adjusted for sex, age and body mass index.

The effect of exercise on plasma insulin, free fatty acid, and glucose uptake and glycogen concentration in soleus, and intravenous glucose tolerance of streptozotocin treated, diabetic Sprague-Dawley rats were studied. Diabetic-trained animals were subjected to a regular program of treadmill running for 4 weeks. Seventy-two hours after the last training session, basal and insulin-stimulated glucose uptake was studied in incubated strips (about 20 mg) of soleus muscle in vitro. Glucose tolerance was measured with intravenous infusion of 0.5 g glucose/kg body weight. In diabetic rats, training was associated with increase glucose uptake in basal and maximal insulin concentrations, decreased fasting glucose concentrations, and increased muscle glycogen levels, but there were no changes in glucose tolerance curve and plasma insulin concentrations. These results suggest that regular running program for 4 weeks improve responsiveness of insulin on soleus muscle, but fails to cause improvement of impaired intravenous glucose tolerance in mild degree streptozotocin induced diabetic rats.

In the present study the effect of exercise on the conversion rate of ingested glucose to glycogen in the different types of hindlimb skeletal muscles in Sprague-Dawley male rats was studied. The amounts of synthetized glycogen from ingested glucose of fast-twitch white (WV), fast-twitch red (RV), mixed type of fast-twitch white and red (EDL), and slow-twitch (SOL) muscles were determined at 30 and 90 min. after ingestion of 25% glucose solution which contained 14C-glucose(2 ml(luCi)/100gm B.W.) in control and exercise loaded rats. The result was summarized as follows: The about 55% at 30 min. and 70% at 90 min. after glucose ingestion were absorbed from gastrointestinal tract. This result shows no effects of exercise on absorption rate from gastrointestinal tract. The amount of synthetized glycogen of SOL from ingested glucose at 30 and 90 min. after glucose ingestion were highest, whether WV were lowest in hindlimb skeletal muscles in control and exercise loaded rats. In the exercise loaded rats, the amounts of synthetized glycogen of SOL, RV, and EDL at 90 min. after glucose ingestion was much higher than control rats, but not different in WV between exercise-loaded and control rats. At 30 min. after glucose ingestion, only SOL of exercise loaded rats was higher than control rats. In the control rat, the synthesis of glycogen was almost completed during initial 30 minutes. On the other hand, in the exercise loaded rat, except WV was opposite result of control rats, i.e., amounts of synthetized glycogen were major during late period. The amount of synthetized glycogen of liver at 30 and 90 min. after glucose ingestion in exercise loaded rats was higher than control rats. The rate of glycogen synthesis in control and exercise loaded rats were higher between 30-90 minute than initial 30 minutes.
