The mortality and morbidity of peritrochanteric fractures in the elderly are great due to preexisting diseases, the osteoporosis, and poor general conditions. Since the complications sometimes lead to death, it is utmost important to reduce the complications and to prevent them. Authors had experienced 42 peritrochanteric fractures over 65 years old from January, 1988 to December, 1992. Age incidence was distributed from 65 to 93 years. The sites of fractures were 17 femoral neck, 24 intertrochanteric, 1 subtrochanteric. The mortality at postoperative 6 months was 10.2%. The postoperative complications were 6 cardiovascular diseases, 3 pneunonia, 3 pressure sore etc. The results according to interval between injury and operation were not significant, but reducing risk factors following check-up of general conditions was significant. It was necessary in treatment of elderly peritrochanteric fractures to check the general conditions, to reduce risk factors, to choose appropriate method of operation and anesthesia, and to operate as soon as possible by experienced surgeon. Postoperative early ambulation was also significant at good results. The percutaneous pinning under local anesthesia was an recommendable method in patients with severely poor general conditions.

Infantile hemangioendothelioma of the liver is a common vascular tumor in infancy. The tumor is usually multinodular or diffuse and classified into two types. We present a case of infantile hemangioendothelioma of the liver, which predominantly consists of type 2. A 4-month-old female was admitted for an evaulation of an abdominal distension. A CT scan of the liver showed a multinodular mass. The right lobectomy was done. Grossly, the mass consisted of round nodules ranging from 2cm to 5cm in diameter. Microscopically, the tumor revealed proliferation of small vascular channels lined by endothelial cells. Bizarre cells and mitotic cells were frequently noted. Vesicular nuclei and multilayering of the endothelial cells were also noted.

Retroviral vector provide a highly efficient method for gene transfer into eukaryotic cells. This vector system can be divided into two components; the retroviral vector itself and the retroviral packaging cell line. The key improvement in the design of these two components are. focused on two aspects; the reduction of helper virus production and high titer-virus. We used PA317 for retrovirus packaging cell line, for its high producibility of viral titer, To test the ability of the vectors to generate high titer-virus, we have chosen four different retroviral vectors; LN, LNSX, LNCX and LXSN. To test easily the viral titer, we have made recombinant construction with CD4 and CD8, checked their viral titer and stained their surface expression. LXSN which contain SV40 early promoter in front of leo gene showed best results in viral transient transfection assay, dot blot assay and surface expression. In addition, recombinant containing CD8 generally showed much higher viral titration and surface expression than CD4.

There are various reports referring to the clinical siignificances and removal of postgastrectomy bezoar. In this case, suture thread were thought to he the important factor of the bezoar formation, This bezoar was removed intaetly uaing fiber-optic endoscope in patinet who had postgastrectomy bezoar, by cutting the thread by biopsy forceps.

Calcareous corpuscles are a characteristic structure found in larval and adult stage cestodes. These corpuscles are known to contain several protein components and to possess protein-binding activity. However, the proteins bound to calcareous corpuscles in situ have not been studied. The present study was undertaken to identify the proteins on calcareous corpuscles. Calcareous corpuscles were purified from the plerocercoids (= spargana) of Spirometra erinacei, and serially dissolved using 0.1 M sulfamic acid solution. Collected supernatants were examined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and silver staining. The results showed that only the fraction remaining after the 19th dissolved fraction contained proteins. A total of 20 protein molecules were detected in gel, with major bands at 56, 53, 46, 40, 35, 29, 28, 24.5, 21, 19, 16, 13, 10 and 8 kDa. In particular, the proteins corresponding to the 21 and 16 kDa bands were most abundant. Our results demonstrated for the first time the protein contents of the calcareous corpuscles of spargana. Further studies on the functions of these proteins are required.

PURPOSE: To determine the incidence, risk factors, and clinical characteristics of pelvic insufficiency fracture (PIF) in patients with cervical cancer. MATERIALS AND METHODS: Between July 2004 and August 2009, 235 patients with non-metastatic cervical cancer were treated with definitive chemoradiation or postoperative radiotherapy. Among 235 patients, 117 (49.8%) underwent the first positron emission tomography/computed tomography (PET/CT) within 1 year after radiotherapy. The median radiation dose was 55 Gy (range, 45 to 60 Gy). Medical charts and imaging studies, including PET/CT, magnetic resonance imaging (MRI), CT, bone scintigraphy were reviewed to evaluate the patients with PIF. RESULTS: Among 235 patients, 16 developed PIF. The 5-year detection rate of PIF was 9.5%. The 5-year detection rate of PIF in patients who underwent the first PET/CT within a year was 15.6%. The median time to development of PIF was 12.5 months (range, 5 to 30 months). The sites of fracture included 12 sacroiliac joints, 3 pubic rami, 3 iliac bones, and 1 femoral neck. Eleven of 16 patients having PIF complained of hip pain requiring medications. One patient required hospitalization for pain control. The significant risk factors of PIF were old age, body mass index less than 23, bone mineral density less than -3.5 SD, and the first PET/CT within a year after radiotherapy. Radiation dose and concurrent chemotherapy had no impact on PIF rate. CONCLUSION: PIFs were not rare after pelvic radiotherapy in cervical cancer patients in the era of PET/CT. Timely diagnosis and management of PIF can improve quality of life in patients with cervical cancer, in addition to reducing unnecessary medical expenses.

Lipiodol, lipid soluble contrast media, was applied to 59 patients, who was clinically suspected to havehepatic tumor, in the department of Diagnotic Radiology, Seoul National University Hospital. The results of theclinical use of Lipiodol were as follows: 1. The clinical diagnosis was hepatocellular carcinoma(HCC) in 50 cases,cavernous hemangioma in 4 cases, metastasis in one case and others in 4 cases. 2. After hepatic arteriography,Lipiodol only was injected in 28 cases, mixture of Lipiodol and Mitomycin was injected in 22 cases andtranscatheter arterial embolization was performed additionally after injection of Lipiodol and Mitomycin in 9cases. 3. Among the 50 cases of HCC, Lipiodol was accumulated in the lesion in 49 cases. However, similaraccumulation of Lipiodol occured in a metastatic cancer and cavernous hemangiomas. 4. Plain radiographic patternsof Lipiodol accumulation could be divided into fine granular type, nodular type and linear or branching type. Thelinear or branching pattern disappeared in follow-up radiography after one week. 5. As minor complication afterLipiodol Injection. GOY &GPT were transiently elevated in 30 cases and normalized in a week. Abdominal pain andfever developed but subsided in a week too. 6. When an appropriate lipid-soluble chemotherapeutic agent orradioisotope is applied to this phenomenon in which Lipiodol is selectively accumulated in hepatic tumor, thediagnostic and therapeutic values will be more enhanced.
