BACKGROUND: Antihypertensive effect and safety of the newer, long acting, nonsulfhydryl angiotensin converting enzyme inhibitor, lisinopril, were studied. METHODS: Twenty eight patients of mild to moderate essential hypertension were administered 10-20mg of lisinopril once daily for ten weeks. Patients were evaluated every two weeks concerning the changes of blood pressure and pulse rate in the sitting position and also any untoward sumptoms and signs attributable to the side effect. Chest X-rey, ECG and laboratory examination were performed in principle two times before and after the completion of medication. RESULTS: The blood pressure declined from 165.4/107.6mmHg to 141.3/92.4mmHg at the end of ten weeks of medication, thus the reduction of 24.1mmHg of systolic pressure and 15.2mmHg of diastolic pressure were observed and the overall effective rate was 85.7%. The pulse rate and laboratory findings were not sigificantly changed before and after the administration of lisinopril. The side effects were observed in 2 cases(7.1%) of mild dry cough and in 2 cases(7.1%) of transitory mild headache and in 1 case(3.6%) of dizziness but no one discontinued medication due to adverse effects. CONCLUSION: Lisinopril proved effective and safe in the treatment of mild to moderate essential hypertension.

High selectivity provided by biomolecules such as antibodies and enzymes has been exploited during the last two decades for development of biosensors. Of particular importance are efficient immobilization methods for biomolecules in order to preserve their biological activities. In this study, we have evaluated immobilization strategies for an anti-DNA antibody on a self-assembled monolayer of omega-functionalized thiols. The antibody was immobilized via peptide bond formation between the primary amines in the antibody and the carboxyl groups on the self-assembled monolayer. The peptide bond coupling was achieved by activating COOH groups on the surface through N-Hydroxysuccimide (NHS)-ester formation, followed by acylation of NH2 group in the antibody. DNA binding activity of the immobilized antibody was examined by counting beta emission from 35S-labeled DNA.

STUDY DESIGNS: Retrospective analysis of the surgical treatment in patients of thoracolumbar spine fractures. OBJECTIVES: To measure by modified Cobb method the correction angle of thoracolumbar vertebral fractures and to comparison the difference between short segment pedicular fixation with fractured vertebra(group A) and without fractured vertebra (group B). SUMMARY OF LITERATURE REVIEW: The major treatment of thoracolumbar spine fractures is surgical correction of kyphotic angle by posterior decompression and posterolat. fusion at one level or more. MATERIALS AND METHODS: The materials are the patients who visited due to trauma beween 1991.1 and 2000.12. and treated by post. decompression and short segment posterolat. fusion with iliac bone graft. The number were A group, 28 persons and B group, 15 persons. The method of radiologic measurement is done by the modified Cobb method. The follow up time is till 2001.7. and the duration are minimal 6 months and maximal 77 months. The age was between 17 old and 60 old. The neurologic abnormalities in patients are 12 persons. The fractures were classified by the Denis classification. There are compressive fracture are 3 persons and bursting fracture type A are 18 persons, type B are 22 persons. The materials were confirmed by radiologic union and excluded if more than one vertebra fusion is needed. RESULTS: The most fractures were due to falldown injury. The most fracture site was T-L level (T12-L3). The one case was complicated by deep infection and treated and the other case was reduction loss due to metallic failure. The results of the loss of correction were A group, 5.3 degree and B group, 6.2 degree. (P>0.05). The relative correction loss were A group, 42%, and B group, 54%. (P<0.05). CONCLUSION: The mean correction angle and loss of correction are more good results in the group of short segment pedicular fixation with fracture vertebra. But to get more good results, our study do more long term follow-up and rule out other statistical errors and consecutive radiologic follow-up.

PURPOSE: To evaluate the anti-apoptotic effect of the antioxidant reaction of anthocyanin on the prostate in an andropause animal model. MATERIALS AND METHODS: Sprague-Dawley rats were divided into three groups (n=12 in each): control (Group I), andropause (Group II), andropause treated with anthocyanin (Group III). For induction of andropause, Group II and III underwent bilateral orchiectomy. Group III was treated with daily oral anthocyanin (160 mg/kg) for 8 weeks. After 8 weeks, the rats were sacrificed and their blood and prostates were examined pathohistologically and evaluated for oxidative stress and apoptosis. Oxidative stress was assessed by the activity of superoxide dismutase (SOD) and apoptosis in the prostate was identified by terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end-labelling assay. RESULTS: Group II showed markedly increased activity of SOD in serum over that observed in Group I, whereas the rats in Group III showed reduced oxidative stress compared to Group II. Despite no significant differences in prostate weight between Group II and III (p=0.078), the apoptotic index was significantly greater in Group II than Group I, and was significantly lesser in Group III than Group II. CONCLUSIONS: We suggest that the oxidative stress caused by low testosterone may be another inducer of apoptosis, and this apoptosis may partly contribute to the overall apoptosis of the prostate in the andropause animal model. Therefore, anthocyanin supplementation may contribute to preventing excessively rapid cell death by apoptosis in the prostate in an animal model of andropause.

Collagen and its products, used in some medical field are relatively safe but may induce hypersensitivity reaction. However, pulmonary embolism is a rare but serious complication after injection of them. A-48-year old woman was admitted because of cough, hemoptysis and dyspnea. Nine days ago, she had received breast augmentation with injectable collagen by unlicensed person. Four days later, she experienced cough, hemoptysis and dyspnea. On admission right side pleural effusion and peripheral distributed diffuse consolidations in both lungs were noted on chest radiograph. A computed tomographic (CT) scan of the chest showed non-segmental distribution of bilateral ground-glass opacity and interlobular septal thickening with multifocal consolidation in both lungs. Sputum and urine cytologic examination revealed foamy histiocytes containing lipid vaculoes. Conservative management was done under the impression of pulmonary embolism after collagen injection. She was dischared with full recovery. Here, we report a case of pulmonary embolism occurred after infection of collagen first in Korea.

PURPOSE: Laparoscopic cholecystectomy is treatment method for management of benign gallbladder diseases. Further attempts are made to operate single-port laparoscopic cholecystectomy. However, single-port laparoscopic cholecystectomy, the procedure remains technically difficult, especially in obese patient. Recently, a robotic surgical system for minimal invasive surgery was introduced to overcome the limitations of conventional laparoscopic surgery. METHODS: From April 2009 to August 2017, we retrospectively reviewed the medical records of patients with single-site, minimally invasive (laparoscopic and robotic) cholecystectomy with high BMI (>25 kg/m2). We analyzed general characteristics and perioperative outcomes between the single-fulcrum laparoscopic cholecystectomy group and the robotic single-site cholecystectomy (RSSC) group. RESULTS: Operation time (57.56±11.10 vs 98.5±12.28 p<0.001) was significantly longer and postoperative pain score (3.61 vs 5.15 p=0.000) was significantly higher in the robotic single-site cholecystectomy (RSSC) group, but the actual dissection time (25.85±11.09 vs 25.79±13.35 p=0.978) was not significantly different between the two approaches. Iatrogenic gallbladder perforation, (13 vs 6 p=0.005), patients undergoing RSSC showed a significantly smaller amount than did those undergoing single-fulcrum laparoscopic cholecystectomy (SFLC). CONCLUSION: It is difficult to say for certain that RSSC is clearly better than SFLC in obese patients. However, because of the technical convenience and efficiency of surgery with RSSC, RSSC can be practically worthwhile. Further study is mandatory.

Laparoscopic pancreatoduodenectomy (LPD) in pancreatic cancer is primarily criticized for its technical and oncological safety. Although solid evidence has not yet been established, many institutions are performing LPD for pancreatic cancer patients, with continuous efforts to ensure oncologic safety. In this video, we demonstrated a case of standard LPD combined with vascular resection in pancreatic cancer.

PURPOSE: There was a global increase in the prevalence of oseltamivir-resistant influenza viruses during the 2007-2008 influenza season. This study was conducted to investigate the occurrence and characteristics of oseltamivir-resistant influenza viruses during the 2007-2008 and 2008-2009 influenza seasons among patients who were treated with oseltamivir (group A) and those that did not receive oseltamivir (group B). METHODS: A prospective study was conducted on 321 pediatric patients who were hospitalized because of influenza during the 2007-2008 and 2008-2009 influenza seasons. Drug resistance tests were conducted on influenza viruses isolated from 91 patients. RESULTS: There was no significant difference between the clinical characteristics of groups A and B during both seasons. Influenza A/H1N1, isolated from both groups A and B during the 2007-2008 and 2008-2009 periods, was not resistant to zanamivir. However, phenotypic analysis of the virus revealed a high oseltamivir IC50 range and that H275Y substitution of the neuraminidase (NA) gene and partial variation of the hemagglutinin (HA) gene did not affect its antigenicity to the HA vaccine even though group A had a shorter hospitalization duration and fewer lower respiratory tract complications than group B. In addition, there was no significant difference in the clinical manifestations between oseltamivir-susceptible and oseltamivir-resistant strains of influenza A/H1N1. CONCLUSION: Establishment of guidelines to efficiently treat influenza with oseltamivir, a commonly used drug for treating influenza in Korean pediatric patients, and a treatment strategy with a new therapeutic agent is required.
