The experiment was designed to investigate type-selectivity of the involved muscle fibers and changes in the component ratios of the fiber types following the progression of disuse atrophy in the skeletal muscle. After inducing disuse atrophy of the skeletal muscle by applying cast on the hind limb, we used histological and histochemical stains in the sections of the rat Tibialia anterior muscles. The results were as follows. 1. Even 8 weeks after immobilization of the hind limb, differentiation of muscle fiber types by histolo gical and histochemical staining methods in the Tibialis anterior muscle could be possible. 2. Atrophy of muscle fibers was more pronounced in type IIB and type I fibers than in type IIA fibers. 3. Central migration of sarcolemmal nuclei and ring fiber appeared after 6th and 8th weeks of immobilization respectively, in the H&E and trichrome preparations. Ac-pase or Alk-pase positive fibem were not noted throughout the experimental periods.

Biofeedback is the treatment of choice for functional defecation disorders such as idiopathic chronic constipation and neurogenic fecal incontinence. The pre-existing biofeedback systems have many disadvantages. The aims of current project are, first, to develop the biofeedback system into the application software in the Windows environment, and, second, to assess the possibility of clinical usage for patients with functional defecation disorders. The hardware and software of the BASCO (Biofeedback Anal Sphincter Control) system were based on the signal measurement and signal processing of anal sphincter EMG (Electromyography). BASCO system was applied to 5 normal healthy controls and 20 patients with functional defecation disorders. Patients group was categorized as constipation group (N1=15) and incontinence group (N2=5). With use of current system, EMG-based biofeedback therapy was performed, and the outcome was analysed. Anal EMG signal data was processed by the software, and displayed in the monitor of personal computer. The software of EMG-display and database management were adequately operated. In N1 group, a paradoxical elevation or equalized activity of anal EMG pattern was shown in the simulated defecation. In N2 group, low electrical activity was shown. These findings were used for the EMG-based biofeedback therapy as a pilot study. The clinical symptoms were improved in 12 of N1 group and 3 of N2 group in the period of 3.7 (range, 1~12) months follow-up. In Conclusion, newly-developed BASCO system was adequately operated in the volunteer and patients groups. The multi-tasking and multi-processing functions were adequately shown in the real time. Current results could be used for clinical appraisal. Specifically, this system could be used for the practical application of biofeedback therapy in the patients with chronic constipation or fecal incontinence.

PURPOSE: To evaluate the effectiveness of transcatheter embolization for the treatment of massive gastrointestinal arterial bleeding. MATERIALS AND METHODS: The study was based on retrospective analysis of twelve cases(8 men, 4 women) including two patients with hemobilia in which transcatheter embolization was attempted for the control of massive gastrointestinal bleeding from March 1987 to October 1993. Clinical diagnoses of these patients were peptic ulcer(5), pseudoaneurysm formation(3) following percutaneous transhepatic biliary drainage or traffic accident, stomach cancer(I), typhoid fever(I), duodenal leiomyoma(1) and Osler-Weber-Rendu disease (1). RESULTS: Embolized vessels are as follows: gastroduodenal artery(6), left gastric artery(2), ileocolic artery(2), and hepatic artery(2). Embolization was effective in immediate control of bleeding in all patients. Although five of the six patients who had undergone embolization of the gastroduodenal artery developed rebleeding within 24 hour, only 2 reguired surgery and none showed serious complication. CONCLUSION: Embolization therapy is safe and effective initial treatment of choice for life-threatening massive gastrointestinal bleeding.

Percutaenous transhepatic biliary drainage (PTBD) is widely used to control cholangitis, sepsis, or jaundice caused by biliary tree obstruction. The PTBD tract can be used in percutaneous biliary stone extraction in pre-or post-operative state when ERCP is failed or operation is contraindicated. We performed 16 cases of percutaneous transhepatic biliary stone removal. Locations of biliay stones are combined intrahepatic and extrahepatic in 8 cases (50%), only extrahepati in 7 cases (44%), and only intrahepatic in 1 case (6%). The number of stones was single in 6 cases and multiple in 10 cases. Over all success rate was 81% (13/16), 93% (14/15) in extrahepatic stones and 78% (7/9) in intrahepatic stones. In 5 of 6 cases, complete stone removal was impossible due to marked tortuosity of T-tube tract or peripherally located stones, complete removal of biliary stones was achieved via a new PTBD tract. No significant pre-or post-procedure complication was occured. Percutaneous removal of biliary stones via PTBD tract is an effective and safe alternative method in difficult cases in the menagement of biliary tract stones.

BACKGROUND: The purpose of this study was to discover ways to screen urine culture specimens through Gram stains, urine stick analyses and microscopic examinations for the laboratory cost saving. METHODS: One hundred and fifty-eight urine specimens for culture were included. Fifty uL of urine were inoculated onto one well each of 10-well slide, dried on the hot plate, and Gram-stained. The results combined with routine urinalyses including urine nitrite and leukocyte esterase, and pyuria, were compared with the routine culture results. RESULTS: The screening of bacteriuria by Gram stains, urinalyses and microscopic examinations revealed the high sensitivity (91.9%) and negative predictive value(95.5%) with cost saving of 41.8% of inoculating media. Not considering the Gram stains, the screening revealed 83.8% sensitivity and 92.5% negative predictive value, even if the cost saving of inoculating media were as high as 50.1%. CONCLUSION: It was demonstrated that it was sensitive and economic and produced rapid preliminary results to screen bacteriuria by the Gram stains combined with urinalyses and microscopic examinations.

An intraosseous epidermal cyst is a rare benign cystic lesion. It is thought to result from congenital factors or trauma and can lead to bone destruction because the cyst develops at the soft tissue around the bone. Radiological findings of intraosseous epidermal cysts are a well-defined radiolucent lesion, with cortical expansion. It is important to differentiate an intraosseous epidermal cyst with other disease developed at distal phalanx because its clinical and radiological findings are similar. We report two rare cases of intraosseous epidermal cysts that developed at the distal phalanx.

Fungal infection has been observed with increasing frequency in recent years because the use of combinations of broad spectrum antibiotics, immunosuppressive agents, and antineoplastic agents is increasing and the survival rate of premature baby is increasing. We experienced a 3 month old male infant with anuria due to bilateral ureteropelvic fungus balls. He was born at 31 weeks gestation period and had been treated with broad spectrum antibiotics for 5 weeks after birth. We removed fungus balls surgically and made nephrostomy bilaterally. And then irrigation of amphotericn B through nephrostomy and systemic amphotercin B injection had performed for 3 weeks. Thereafter fungus balls completely disappeared.

PURPOSE: To evaluate the cilinical results of transjugular intrahepatic portosystemicshunt(TIPS) for the control of variceal bleeding. MATERIALS AND METHODS: TIPS creation was attempted in 23 patients with endoscopically confirmed variceal bleeding. Most patients had multiple episodes of bleeding in the past and have been treated with multiple endoscopic sclerotherapies. Pre- and post-procedural hepatic and portal vein pressures were measured. After creation of TIPS patients were followed up at regular intervals. RESULTS: TIPS has been successfully accomplished in 22 of 23 patients using Wallstent(n=21 ) and Strecker stent(n=1 ). Immediate bleeding control was achieved in all patients with shunt creation. No procedure-related complication was noted. Portal vein pressure was reduced from 30.7+/-5.8 mmHg to 20.8+/-4.7 mmHg. The mean pressure gradient of portosystemic shunt dropped from 22.8+/-6.0 prior to TIPS to 12.2+/-4.1 immediately after. During the follow-up period (6-556 days, mean; 10months), seven patients died; progressive hepatic failure (n=4), variceal rebleeding(n=2), and respiratory failure(n=1). Hepatic encepha-Iopathy after TIPS was noted in 7 patients(31.8%). Variceal rebleeding occurred in 3 patients(13.6%). The remaining 15 patients have survived an average of 11 months. CONCLUSION: This results suggest that TIPS is a safe and effective method for lowering portal pressure and controlling variceal bleeding. Furthermore if these initial results are encourged by further long-term observation, TIPS could replace endoscopic and risky surgical intervention.
