Gastric bezoars are large masses or concretions, composed with plant fiber, hair and miscellaneous foreign bodies, found in the stomach and occur usually as sequele of gastric surgery. We experienced 2 cases of fat bezoars which developed after drinking of melted beef fst. They had postprandial epigastric fullness and pain, those were relieved on supine and left recumbent position. Upper gastrointestinal series showed a large movable mass in the stomach in hoth cases. On gastrofibercopic examination, a large egg sized white bezoar was cordirmed in both cases and a gastrie ulcer at antrum associated in one case. In attempt to removal of the bezoars, we tried to break them, but failed because of its character. The patients were treated with pancreatic lipase containg digestives, Pancreon-F and Azintal. From one day after this treatment, symptoms were completely relieved. Five days later, we confirmed disappearance of bezoars by gastrofiberscopy. and upper gastrointestinal barium

Antigen-specific T cell activation requires interaction of the T cell with specialized antigen-presenting cells. Signaling through the TCR is necessary but not sufficient to induce antigen-specific T cell activation and cytokine secretion. This first signal, termed signal 1, is both antigen-specific and MHC-restricted. Signal 2, which is neither antigen-specific nor MHC-restricted, is necessary to induce cytokine secretion, cellular proliferation, and effector function. Recently immunological studies in T cell activation area are mainly focused on biological and molecular biological characterization of TCR/CD3 complex and accessary molecules providing costimulatory signal (signal 2). If signal 2 is not delivered, T cell enter a state of long term un-responsiveness to specific antigen-termed anergy. Monoclonal antibody technique has been especially involved in recognizing novel inducible cell surface antigens on T cell activation. This study was aimed to develop monoclonal antibodies recognizing novel cytoplasmic proteins present in activated T cells. We make 6 monoclones involved in changing pattern of T cell activated cytoplasmic proteins. Using these 6 monoclonal antibodies analyze to find novel molecules involved in T cell activation associated response, apoptosis, and/or heat shock response of the T cells in early T cell activation.

Mirizzi syndrome is an uncommon cause of obstructive jaundice. It consists of the following elements: (1) an anatomic arrangement of the cystic duct such that it lies almost parallel to the common hepatic duct, (2) impaction of a gallstone in the cystic duct or neck of the gall bladder, (3) partial mechanical obstruction of the common hepatic duct by the stone itself or the resulting inflammatory reaction, and (4) recurrent cholangitis or ultimately cholangitic cirrhosis due to the partial obstruction.

Esophageal ulcers induced by doxycycline is a rare complication. These patients usually complain of sudden onset of symptoms, ie acute substernal or chest pain and odynophagia without prior hietory of esophageal syraptoms. On esophagoscopic examination, there are upper or midesophageal ulcers, which heal after diseontinuation of the drug within 2 weeks. A history of ingestion of the doxycycline,with liquid jost before bedtime can be elicited. The exact eause of the xaucosal ulceration is not clear, but a direct irritant effeet on esophageal mucosa seems most likely. We report 5 cases of esophageal uleeration secondary to the ingestion of doxycydine. Esophagoscopy revealed esophageal ulcers in all patients and the patients hecame asymptomatic following stopping of tbe drugs and taking antacids.

OBJECTIVE: The prescription rates of long-acting injectable (LAI) antipsychotics are very low around 1% in Korea. This study was aimed to explore the preference of LAIs in patients with schizophrenia, who are currently living in community, and their caregivers. METHODS: The patients, diagnosed with schizophrenia by DSM-IV TR and were registered in the 31 mental health centers of Gyeonggi province and their caregivers were inquired the knowledge of the LAIs. The questionnaires contained information such as demographic characteristics, history of psychiatric treatment, and so on. RESULTS: About 5,318 were registered in 31 community mental health centers of Gyeonggi province in February 2012. The questionnaires of 614 patients and 365 caregivers were gathered from 20 community mental health centers. The mean ages (+/-SD) of patients and caregivers were 41.9 (+/-10.2) and 62.2 (+/-13.4) years old, respectively. 272 patients (44.6%) had experienced the discontinuation of medications without doctor's consent. 217 patients (35.9%) and 97 caregivers (27.1%) knew about the LAIs. The preference rates for LAIs were 35.2% and 46.8% for the patients and caregivers, respectively. CONCLUSION: There is still huge discrepancy between the preference and the real prescriptions of LAIs in community-dwelling patients and their caregivers, much higher than in those of hospital settings. This study suggests that both patients and caregivers registered in the community mental health centers have a strong commitment to live in the community. The obstacles against the benefits of LAIs need to be resolved.

Congenital pseudarthroses and non-unions have been recognized as some of the most challenging problems in orthopaedic surgery. with a standard surgical procedure, such as bone grafting, nailing, plating or a combination of these, it was frequently failed to unit. After repeated surgical failures, amputation has been the main course. With the advent of an electrical control of osteogenesis, however, this dismal outlook is brightening. The earliest report of the use of electrical energy to directly stimulate bone healing seems to be in 19th century, but it was not reliable. In this century, the electrical properties of bone were first described by Yasuda et al in 1953. After then, several investigators have shown that the application of small amounts of the electrical current to bone stimulates osteogenesis at the site of the cathode. Clinical trials using various froms in the treatment of delayed union, non-union, and congenital-pseudarthrosis began early in the 1970's. Constant direct current, pulsed current, and electromagnetically induced current have all been used clinically to heal bone defects with varying degrees of success. But, to-this date it is unknown what is the mechanism of stimulating bone healiag with electricity, and which from of electricity is most efficient in stimulating osteogenesis. We have experienced direct current stimulation to promote osteogenesis in 9 cases of non-union and 4 cases of congenital pseudarthses of the tibia from august, 1978 to december, 1980. Of 9 non-unions, 7 (77.8%) achieved solid bony union. We had obtained bony union in 4cases of non-union only with the electrical stimulation. In 4 cases of congenital pseudarthses of the tibia, all cases achieved solid bony union with the electrical stimulation and bone graft, but in 3 cases, refractures were occurred. At this moment, our conclusions from this study are as followa. I. Direct current stimulation is one of the reliable methods inducing ostengenesis. 2. Regular follows-up and determination of the stimulator integrity are essential steps in the electrical stimulation. 3. Combined treatment with the electrical stimulation and bone graft have markedly improved the success rate. 4. In direct current stimulation of congenital pseudarthsis, the mechanically sound bony alignment, massive bone graft and protection using long leg brace seem to be mandatory procedures.

During a 12-month period high-resolution, real-time ultrasonography (US) with graded compression was performed on 268 consecutive patients with clinically suspected acute appendicitis and its complication. US visualization of a fluid-filled, non-compressed appendix or a decompressed, thick-walled appendix was the primary criterion for a diagnosis of acute appendicitis. The sonographic findings were correlated with surgical-pathologic outcome in 92 cases and with the findings of clinical follow-up in the remainder. US was found to be accurate in the diagnosis of acute appendicitis and its complication with a sensitivity of 93.3%, a specificity of 98.9%, and an accuracy of 97%. The predictive value of a positive test was 97.7%; that of a negative test was 96.7%. There were two false-positive examination in patients with a thick-walled appendix or periapperdiceal abscess, which were surgically confirmed as appendiceal adenocarcinoma and perforated cecal diverticulitis respectively. There were six false-negative examination in patients with a sonographically no-visible appendix, which were confirmed surgically as acute appendicitis(n=5) and perforated appendicitis(n=1). Our results show that high-resolution, real-time US is an accureate imaging modality in the diagnosis of acute appendicitis and the evaluation of its complication.
