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.

Primary biliary cirrhosis, a chronic, progressive, and often fatal cholestatic liver disease, is characterized by destruction of intrahepatic bile ducts, portal inflammation and scarring, and the eventual development of cirrhosis and liver failure. We reviewed four cases of primary biliary cirrhosis primarily suspected with peritoneoscopic liver biopsy specimens. All patients were female and their age ranged from 29 to 50 years(median age: 43.8 years). Presenting symptoms were typically pruritus and/or upper abdominal discomfort. On physical examination, interus was presented in 3; hepatomegaly in 3; chronic liver disease stigmata in one. Co-existing autoimmune diseases such as Hashimoto' thyroiditis and Sjoegren' syndrome were found in 2 cases. Biochemical tests of liver function revealed a cholestatic pattern. An antimitochondrial-antibody test was positive in 2 out of 3 patients(75%). Increase levels of serum immunoglobulins, especially of IgM, were evident in 3 cases. Histologic staging(Ludwig et al.) disclosed stage I lesion in one, stage III in two, and stage IV in the remaining one.

The Duodenal diverticulum is the rare cause of the common bile duct obstruction. We experienced a case of the diverticulum of the second portion of duodenum in a 59-year-old male, who complained recurrent attacks of right upper abdominal pain and fever since 16 months prior to admission. Duodenoscopic finding and UGI study revealed a typical duodenal diverticulum just side to the papilla of Vater. Diverticulectomy and cholecystectomy was performed and after than, he has been free front above mentioned symptoms. We reported a case of duodenal diverticulum which caused recurrent common bile duct obstruction.

PURPOSE: To compare the suppressive effects in hepatocellular carcinoma patients of transhepatic arterial chemoembolization by the infusion of adriamycin-lipiodol emulsion and of this plus 10ml of cisplatin solution. MATERIALS AND METHODS: In a total of 151 cases, the frequency of intrahepatic recurrence was compared with follow-up angiographic findings after the first and second transhepatic arterial chemoembolization with adriamycin-lipiodol emulsion and adriamycin-lipiodol emulsion plus 10ml of cisplatin solution, respectively. RESULTS: Among 46 patients whose first single infusion was after mean 119 days, the recurrence rate was 22% ; for 42 who were given their first multiple infusion after mean 76 days this rate was 5% ; for 35 whose second single infusion was administered after mean 147 days, the rate was 34%, and among 28 whose second multiple infusion was after mean 110 days, the rate was 43%. CONCLUSION: During the first trial of transcatheter arterial chemoembolization with adriamycin-lipiodol plus cisplatin solution, hepatocellular carcinoma recurred much less frequently, but during the second trial with cisplatin, recurrence was not suppresed.

In the past two decades, open reduction and internal fixation has been the preferred treatment of posterior pelvic ring disruption with instability. Despite of rigid fixation, it can induce bleeding, wound infection, wound necrosis and prolong operation time in the patient with combined injuries. To compensate for these disadvantages, we have implemented closed reduction and percutaneous iliosacral fixation under fluoroscopy in reducible posterior pelvic ring disruption. In spite of anatomical risk during screw insertion, the percutaneous iliosacral screw technique after closed reduction of the posterior pelvic ring disruption minimally violates the soft tissue envelope and reduces both the operative blood loss and infection rate. We are reporting the early results of our 6 patients treated between Aug. 1995 to Aug. 1996. The operation time was shorter than open reduction and internal fixation. There was no significant bleeding, wound infection and nerve injury by screws.

The effect of persistant mild hyperglycemic hyperinsulinemia on the development of the insulin resistance in rats was studied in vivo. Also, the characteristics of the insulin resistance compared with the insulin resistance of STZ diabetic rats. Persistant mild hyperglycemic hyperinsulinemic rat model was produced by ingestion of glucose polymer for 8 days. The glucose disappearance and infusion rate was measured by hyperinsulinemic euglycemic clamp to"Imique at steady state of blood glucose and insulin levels. The clamped level of blood glucose was 100 mg/dl, and the clamped levels of insulin were 70 pU/ml (physiologic condition) and 3000 pU/ml (supramaximal condition). Hepatic glucose producticon rate was calculated using measured data. And the glycogen synthetic capacity of skeletal muscle(soleus) and liver was measured after 2 hours of hyperinsulinemic euglycemic clamp study. The glucose disappearance and glucose infusion rate in glucose polymer group was decreased in the both physiological and supramaximal insulin level compared to the rate of the normal control group. The rate of STZ diabetic group wase lowest at supramaximal insulin level among two another experimental groups. The hepatic glucose production rate of glucose polymer group was decreased compared to normal control but increased in STZ diabetic group.
