BACKGROUND: Inflammatory mediators, including oxidants, play a important role in the systemic response to burn injury and cause a sepsis and subsequent multiple organ failure by lipid peroxidation of cell. It has been known that vitamin C has potent antioxidant effect and inhibits the lipid peroxidation. This study was designed to evaluate the inhibitory effect of vitamin C about lipid peroxidation in the early stage of bum injury. METHODS: 15 rats with second degree bum on 30-35% of body surface were divided into three groups. Only normal saline was injected into intraperitonial space on the control group , and vitamin C of 50 mg/kg of body weight was added on the low dose group (LDG), and vitamin C of 500 mg/kg of body weight on the high dose group (HDG). After 24 hours of bum damage, biochemical levels of malondialdehyde (MDA), superoxide dismutase (SOD) and catalase were measured in lung and liver tissue. The statistical methods used were Kruskal-Wallis test and Mann-Whitney test. RESULTS: MDA levels of LDG and HDG were significantly low compared to that of the control group (p<0.01). On the catalase activity, there was no significant difference when comparing the control group with LDG (p=0.015), but significant difference with HDG (p<0.01). There was no significant differences between three groups on the activities of SOD (p>0.01), except comparing the control group with HDG in lung tissue (p<0.01). CONCLUSION: Vitamin C therapy in the early stage of bun decreased the level of MDA and increased the catalase activity. It means that vitamin C inhibits the lipid peroxidation and has antioxidant effect. But vitamin C revealed the only partial effect on the SOD activity.

The primary hyperparathyroidism, accompanied with a wide scope of bone resorption in every bone matrix of the body, cyst formation, deformity and pathologic fracture, is a generalized disease which causes atrophy and weakness of skeletal muscle and a disturbance of the digestive system as well as renal function. The primary cause of this disease is an adenoma and a hyperplasia of the parathyroid gland. However, all the progress of the disease can be stopped through surgical excision. The authors medically confirmed the diagnoses through typical radiologic findings, electrolyte and enzyme level of serum and urine and by carotid arteriography on four patients(a 41 year ald male, and 28, 35 and 36 year old females) who had complained of generalized weakness, pain and motion limitation. The authors obtained the following results after surgical excision and continuous follow-up study with medication for 7 years, 3 years, 17 months and 13 months each: 1. Of the four cases, 3 cases were female patients and 1 case was a male patient which showed females outnumbered males 3 times in our study. 2. By age distribution, most cases fell in middle age. 3. All the cases were chief cell type of adenoma. 4. It is conjectured that the symptoms has nothing to do with age or history. 5. In all the cases, serun calsium showed a marked decrease immediately after the surgery but recovered to normal limits within 2 months. 6. In all the cases, serum phosphorus showed an irregular increase immediately after the surgery but also stavilized gradually to normal limits within 2 to 3 months. 7. In all the cases, serum alkaline phosphatase was stable for 3 months after the surgery, then gradually decreased. 8. According to the X-rays, subperiosteal resorption of phalangeal bones almost completely disappeared in 3 months. Cyst and brown tumor disappeared in 6~12 months. Granular mottling of the skull almost completely disappeared in 6 months. Intra articular calcification in 2 cases almost completely disappeared in 6 months, 3 cases which showed loss of lamina dura developed edentia during treatment. 9. In 4th case, small multiple cysts and several small brown tumors of the pelvis healed well, but several lager ones were still unhealed after 10 years of treatment. In first case, the cyst in proximal shaft of the left femur is reduced in size but still evident after 7years of treatment. This case needs further study and observation.

PURPOSE: The objective of this study was to evaluate the findings of ultrasonography (US) in patients withis-chial bursitis. MATERIALS AND METHODS: Our study included 27 patients (mean age 62 years) who underwent US fora painful mass or tenderness in the buttock area. In six of these 27, serous fluid was obtained by needleaspiration, and in five cases, bursal excision permitted histologic confirmation. The other sixteen patients werefollowed up for one or two months with only NSAID medication; all showed some improvement or remission of symptoms. Using a 5-10 MHz linear array probe, US examination was performed while the patient was lying facedown. US images were analyzed with regard to location and size of the lesions, thickness of cyst wall, thepres-ence of internal septa or mural nodules, echogenicity of the cyst wall, fluid content, internal septa,compressibility by a probe, and Doppler signals within the cyst wall. RESULTS: In all 27 patients, ischialbursitis was located superficially to ischial tuberosity. Lesion size(maximum diameter) was 1.5-7(mean 3.8)cm, andthe cyst wall was 0.2-0.8cm thick. Internal septa and mural nodules were seen in 12 cases (44%) and 13 cases(48%), respectively. The cyst wall was identifiable in 21 cases (78%), appearing as a single layer with lowechogenicity (n=10) or with high echogenicity (n=1); it also appeared as two (n=6) or three (n=4) layers ofdifferent echogenicities. When internal septa were present, fluid within the cyst was low echoic in 59% of cases,high echoic in 30%, and of mixed echogenicity (so-called compartmentalization) in 15%. In all cases, the cystbecame deformed, when compressed by a probe. In all patients who underwent doppler examination, some vascularitywas found within the cyst wall. CONCLUSION: US helped to detect ischial bursitis; US findings were thin-walled cystic lesion located superficially to ischial tuberosity, with or without internal septa and mural nodules, andeasy compressibility.

BACKGROUND/AIMS: Endoscopic biliary sphincterotomy (EST) has a very important role in the treatment of pancreatico-biliary diseases, but it has complications. We retrospectively investigated whether the types of electrosurgical currents affect occurence of complications. MEHTODS: In pancreatico-biliary diseases, consecutive 150 patients undergoing EST with pure cutting current (cutting group) and then consecutive 150 patient with blend current (blended group) were studied in respect to post-EST complications and the presence of periampullary diverticulum and papillitis in major papilla. Major bleeding was defined as a decrease in hemoglobin of at least 2 g/dL. Clinical pancreatitis was defined as abdominal pain with elevated serum amylase above three times about the upper normal limit after 48 hour. RESULTS: Major bleeding has not occurred. Minor bleeding occurred in 25/300 patients (8.3%), but was not different in cutting group (n=150) and blended group (n=150). Except 54 patients with elevated amylase before procedure, pancreatitis occurred in 13/246 patients (5.3%), but was not different in cutting group (n=122) and blended group (n=124). Two cases in blended group had moderate pancreatitis. There was no differences of bleeding, pancreatitis, in patients with diverticulum (n=112) and without diverticulum (n=188). Minor bleeding was more common in patients with papillitis (n=24) than without papillitis (n=276) (p=0.000), but the incidence of post EST pancreatitis was similar. In 235 patients with choledocholithiasis, there was no difference in terms of bleeding, pancreatitis in cutting group (n=120) and blended group (n=115). CONCLUSIONS: Post- EST bleeding and pancreatitis were not affected by the types of electrosurgical current used. When EST was performed in patient with papillitis, minor bleeding was observed commonly.

Intrapelvic pin migration of the Kirschner wires or the Steinman pins that are used for the treatment of hip fracture is rare, but it can be serious when it occurs. We experienced a delayed intestinal injury that was caused by the migration of an intrapelvic pin, and this happened 10 years after performing fixation for an acetabular fracture. For preventing this potential complication, the pins have to be used only as a temporary fixation and the end of the pins should be bent. Further, the patients should be followed up clinically and radiographically for a long time. If pin migration does occur, the pin should be removed.

A non-isotopic in situ hybridization method with biotin-labelled oligonucleotide probes was used to examine growth hormone(GH) and prolactin(PRL) gene expression in 32 patients with pituitary adenomas; 13 were prolactinomas, 8 GH secreting adenomas, and 11 mixed GH and PRL secreting adenomas.Positive immunostaining for GH was found in all patients with GH secreting adenomas, and mixed GH and PRL secreting adenomas. Positive immunostaining for PRL was found in all patients with prolactinomas and 9(81.8%) of 11 mixed GH and PRL secreting adenomas, 5(62.5%) of 8 GH secreting adenomas. Immunohistochemistry revealed that 13 were lactotrope adenomas, 5 somatotrope adenomas, and 14 GH and PRL cell adenomas.In situ hybridization revealed that GH mRNA expression was found in all the patients with somatotrope adenomas and GH and PRL cell adenomas, and 6(46.1%) of 13 lactotrope adenomas. PRL mRNA expression was 100% in lactotrope and GH and PRL cell adenomas, and 4(80.0%) of 5 somatotrope adenomas.The patients with a clinical diagnosis of acromegaly had detectable PRL mRNA in their neoplasm and it is suggested that the PRL cells in the adenomas did not result from dedifferentiation, but from the neoplastic stimulus for some mixed tumors probably occurred in cells previously committed to produce PRL and GH. In lactotrope adenomas, the PRL cells of the patients without expression of GH mRNA may be arised from cells programmed to secrete PRL or precussor PRL cells rather than from mixed GH-PRL cells. The finding that some patients produced mRNA detectable by in situ hybridization, but no hormone detectable by immunohistochemistry within tumor was suggested of a silent adenoma.These observations indicated that in situ hybridization studies may improve the classification of pituitary adenomas and may provide a precise knowledge of the biology of these neoplasms.

PURPOSE: This study was performed to investigate the clinical features of large cell neuroendocrine carcinomas (LCNEC). MATERIALS AND METHODS: We retrospectively reviewed the histopathology and clinical information of 37 patients with LCNEC, diagnosed between June 1992 and May 2002 at the Severance Hospital, and performed immunohistochemical (IHC) staining. RESULTS: The prevalence of LCNEC among primary lung cancers was 0.3%, 37 out of 13, 012 cases over a 10 year period. The mean age was 61+/-12 years old, with 34 (92%) males and 3 (8%) females. 30 patients smoked, with an average of 42 packs per year. A cough was the most frequent symptom. The tumor was located at the periphery of the lung in 24 cases (65%). Among the 30 cases that underwent surgery, 4 were diagnosed pathological stage IA, 11 IB, 1 IIB, 13 IIIA and 1 IIIB. The 7 clinically non-operable cases were IIIB in 3, and IV in 4. The positive rates of CD56, thyroid transcription factor-1 (TTF-1), chromogranin A, synaptophysin and 34betaE12 for tumor cells were 88.9, 55.6, 42.1, 31.6 and 21.1%, respectively, from the IHC staining. The median survival time and 5 year-survival rate were 24 months and 27%, respectively. The group that underwent surgery had a better prognosis than those that did not. CONCLUSION: The positive rates for the tumor markers varied, but those of the CD56 and TFT-1 were the highest. The possibility of LCNEC needs to be evaluated for the following situations: small cell carcinomas located at the periphery and not responding chemotherapy, small cell carcinomas diagnosed by percutaneous needle aspiration, poorly differentiated non-mall cell carcinomas, with uncertain histologic type, and unclassified neuroendocrine tumor, etc.
