Abstract PDF: 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.

Abstract PDF: The effects of insulin and exercise on glucose uptake of skeletal muscle were investigated in soleus muscle isolated from low dose streptozotocin induced diabetic rat in vitro. Glucose uptake was assessed by measuring ³H-methylglucose uptake in vitro. Basal glucose uptake in diabetes was reduced by approximately one-third of the control value (5.6±0.73µMol/g/20min. in diabetes versus 8.4±0.77 in control, P<0.01). There was also a significant decrease (P<0.01) in glucose uptake of diabetes at physiologic insulin concentration (200 µIU/ml) by 40% (6.1±1.20 versus 10.0±0.81). Furthermore, maximal insulin (20000 µIU/ml)-stimulated glucose uptake was 36% lower in diabetes as compared with control (7.3±1.29 versus 11.4±1.29, P<0.01). In contrast, exercise (1.0 km/hr, treadmill running for 45 min.) effect on glucose uptake was so dramatic in diabetes that glucose uptake at basal state was 8.+1.09 and insulin stimulated-glucose uptake were 10.2±1.47 and 11.9±1.64, in 200 and 20000 µIU/ml added insulin, respectively. These results suggest that insulin insensitivity develops in skeletal muscle after 2 weeks of streptozotocin-induced diabetes, but these insensitivity was recovered significantly by single session of running exercise.

Abstract PDF: The one event on signaling mechanism is the cleavage by adenyl cyclase of ATP into second messenger, cyclic AMP. The other transfer system of inositol metabolism, it is widely recognized that hydrolysis of the minor membrane lipid phosphoinositide bisphosphate (PIP₂) initiated by occupation of certain receptors and catalyzed by phospholipase C, lead to toe generation of the two intracellular messengers, inositol triphosphate (IP₃) and diacylglycerol (DG). IP₃ is converted to inositol tetrakisphosphate (IP₄) by IP₃ kinase. In the present study, it is that purification of calmodulin is used by phenyl-Sepharose CL-4B chromatography, it's molecular weigh, 17,000 in SDS-polyacrylamide gel electrophoresis. In order to observe the affinity between calmodulin (CaM)-Affigel 15 and IP₃ kinase, and isolated IP₃ kinase, was applied in CaM-Affigel with Ca²⁺ equilibrium buffer and EGTA equilibrium buffer. We compared with binding and elution effect of IP₃ kinase in several condition of buffer. In affinity of binding, Ca²⁺ equilibrium buffer was in the most proper condition, and elution, CaM/Ca²⁺buffer (CE 1 10.36, CE2 12.76pM/min/mg of protein) was effected much more than EGTA buffer (E2 1.48, E 2.43pM/min/mg of protein), but CaM/Ca²⁺stimulate the activity of IP₃ kinase. And then, several detergents such as sodium deoxycholate, tween 20, cholic acid, polyethylene glycol, chaps were applied. The 0.2% chaps buffer (E2 23.19, E3 8.05pnM/min/mg of protein) was the most effective in elution of IP3 kinase.

Abstract PDF: A clinical analysis was done on 23 patients (24 hips) with fracture of the femoral neck, who had been admitted and treated at our Orthopedic department during the period of 4 years, from Jan. 1984 to May 1988. The results were as follows 1. 23 patients were comprised of 4 males and 19 females, and 11 patients were over 65 years old. 2. 18 cases of 24 cases were due to minor traumas such as slipping down, and for over 65 years old, all cases were due to simple minor traumas, 8 cases were showed a severe osteoporosis, below grade 3 of the Singh's index. 3. 14 cases of 24 cases were displaced subcapital fractures, and 6 cases displaced transcervical fractures. Only 4 cases were the undisplaced transcervical fractures. 4. In treatment of fractures internal fixations after manipulation were performed in 14 cases and primary arthroplasties in 10 cases. Secondary arthroplasties were done in complicated 4 cases of 14 cases treated with internal fixations. 5. Complications after internal fixation were developed in 7 cases out of 14 cases, avascular necrosis in 6, nonunions in 2, pin migrations in 3, and metal failure in 1 case. 6. In 14 arthroplasty immediate surgical fitness of femoral stem were related to late loosening of femoral stem (correlation coefficient γ=–0.68, p<0.01).

Abstract PDF: The author fractographically analyzed the cause of metal failure (the first time this procedure has been used for this metal failure) and also analyzed in clinically. In this study, I selected eight cases which have been analyzed fractographically. In all these cases, the analysis was done after treatment of metal failure of implants internally fixed to femur shaft fractures at the Department of Orthopedic Surgery, Yeung-Nam University Hospital during the six year period from May 1983 to September 1989. 1. Metal failure occurred in five dynamic-compression plates, one Jewett nail, one screw in Rowe plate, and one interlocking nail. 2. The clinical cause of metal failure was deficiency of medial buttes in five cases, incorrect position of implant in one case, and incorrect selection of implant in two cases. 3. The time interval between internal fixation and metal failure was four months in one case, between five months to twelve months in six cases, three years in one case. 4. The fractographically analytical cause of metal failure was ; first, impact failure, one case, second, fatigue failure, six cases, machining mark (stress riser), four case type: low consistent cyclic fatigue failure irregular cyclic fatigue failure third, stress corrosion crack, one case. 5. 316 L Stainless Steel has good resistance to corrosion. However, when its peculiar surface film is destroyed by fretting, it shows pitting corrosion. This is, perhaps, the main cause of metal failure. 6. It is possible that mechanical injury occurred in implants during the manufacturing of implants or that making a screw hole in the main cause of metal failure.

Abstract PDF: Autologous Transfusion, storage of one's own blood for subsequent infusion if needed, is safe and effective in a variety of scheduled operative procedures. Obstetric involvement in such programs in very limited, however, because of concern over the possibility of inducing premature labor or causing fetal distress by blood volume change or vasovagal reactions. We describe our experience with pregnant women in this program. The incidence of vagovagal reactions of autologous donation was 9.5% (2.21). After entry into this program, 17pastients received a total 37pints, which consist of 19 Autologous and 18 Homologous. Homologous transfusion was avoided in 30% of patients receiving blood. The values of the mean hematocrits before and after hpebotomy were 34.1% and 31.8% respectively. It was stastically significant (p<0.01). We recommended that autologous blood donation by pregnant women in third trimester is safe for mothers or infants and it should be strongly encouraged for patient with placenta previa and repeated cesarean section.

Abstract PDF: The stereotactic radiosurgery using ionizing radiation of high energy is a technique for exadicating intracranial small tumors, which are inaccessible or unsuitable for open surgical technique. For such a small field radiosurgery, TLD or film dosimetry is essential. The three dimensional dose planning of radiosurgery was performed with dose planning computer system (Therac 2300). The target dose distribution and its error according to patient position were discussed. And were measured of circular cone which specially designed in our Hospital. The position error of Rando Phantom compared with CT were 0.4 mm in the AP-LAT section and in the AP-VERT section, 1.0 mm in the AP-VERT 45°section. The ratio of accuracy of the gantry and couch rotation were 1.5 mm diameter for central axis of 18MeV linear accelerator. Our study suggested that radiosurgery of small field in out department will be appropriate for clinical application.

Abstract PDF

Human Fasciola hepatica infection is a rare entity involving infestation of the liver and biliary tree with adult flukes, which can result in hepatitis, cirrhos is and biliary tract inflammation, obstruction and lithiasis. The patient had the typical diagnostic tetrad of fever, eosinophilic leukocytosis, tender hepatomegaly and fluke ova in the stools. Treatment consists of Emetine hydrochloride hydrochloride administration for hepatic involvement and common bile duct exploration for removal of flukes, with cholecystectomy for associated cholelithiasis. The combination of medical and surgical therapy can be expected to produce an arrest of this infection. The removed liver revealed eggs of the fasciola species in the intrahepatic bile duct. The clinical history, pathological findings and treatment of this case were described.

Abstract PDF: We report 2 cases of midface defect reconstructed with latissimus dorsi myocutaneous free flap. In these cases, the main points to cover the defects were as follows: 1. For the contour of zygoma and maxilla, it was well preserved without bone graft which was not used for second stage reconstruction. In first case, for application of artificial eyes and in second case, for operation after full development. 2. For the drainage of paranasal sinuses, we made the nostril with skin graft, and it was well preserved without any complications during follow up. 3. It was sufficient to cover the defect with latissimus dorsi muscle well designed before surgery and thick enough to fill the defect. 4. In second case, the remained defect of palate and maxilla was not covered for the appropriate reconstructions after full development. In conclusions, we experienced two cases of midface defect reconstructed with latissimus dorsi myocutaneous free flap without any complication and with good results.

Abstract PDF: Lipomas are common soft tissue that are usually located in the subcutaneous tissue. And intramuscular lipomas commonly arise in the upper and lower extremities, where they usually involve the large muscles. Intramuscular lipoma, also referred to as an infiltrating lipoma, is an unusual benign slow growing tumor composed of mature fat cell interdigitating with skeletal muscle. However, intramuscular lipomas are exceedingly rare in the face. We have been experienced a case intramuscular lipoma that located in the malar area. Because of the rarity of these tumors and their propensity to recur without adequate surgery, the case report is presented here. Achievement of surgical margin is essential as the recurrent rate may be as high as 15% to 62.5% without complete excision.

Abstract PDF: A case of sporotrichosis misdiagnosed as lupus vulgaris was presented. A 56-year-old woman had been to pea sized, nontender pustules and a hypertrophic-scar-like nodule on the right thigh. She denied any trauma before the lesions developed. Histopathologic findings from the lesion showed tuberculosis-like granulomatous changes. And she was diagnosed as lupus vulgaris. She also had pulmonary tuberculosis and had been treated with antituberculous drugs for 1 year. But skin lesions was not cleared. We suspected the lesions as one of deep mycoses and could confirm sporotrichosis by mycologic studies. They showed characteristic gross colonies and microscopic findings of Sporothrix schenckii..

Abstract PDF: The primary treatment modality of malignant tumors of the nasopharynx is radiation therapy owing to its inaccessibility to surgical intervention. Over the last two decades there were many changes in techniques of delivery, which include the use of higher doses of radiotherapy, the use of wide radiation field, including the elective radiation of the whole neck, the combined use of brachy- and teletherapy, and the use of split-course therapy. In spite of these advances local and regional recurrences remain the major cause of death. As a boost therapy after external irradiation, high-dose-rate intracavitary irradiation using remote control afterloading system (RALS) was used in two patients. Our results were satisfactory, however, this procedure should only be performed by those who have developed enough expertise in the use of intracavitary techniques for the treatment of nasopharyngeal cancer and have a supportive team including a physicist, dosimetrist, nurse, and trained technologist.

Abstract PDF: Portal vein anomalies include absence, duplication, and malposition (preduodenal portal vein). Duplication of the portal vein or a preduodenal portal vein are hazards at the time of biliary or duodenal surgery, or liver transplantation. Preduodenal portal vein, which was first reported by knight in 1921, is extremely rare congenital anomaly and may cause duodenal obstruction. Recently, we experienced a case of preduodenal portal vein associated with dextrocardia, situs inversus, and duodenal obstruction in a 3 days old male newborn and report with review of the references.

Abstract PDF: The authors developed a comfortable program for routine work of surgical pathology. We used IBM PC (80386) and Foxbase plus program. The main function of this program was automatic coding and concurrent surgical report printing. During gross printing, previous biopsy number and its diagnosis were automatically searched and printed below gross description. The reported data were stored during surgical report printing simultaneously, and thus the typist's workload became considerably reduced. Search for specific cases could be performed by patient's name, surgical number, hospital number, diagnostic code numbers (SNOMED code micro glossary), and certain disease entities on very short duration.
