The purpose of this study was to investigate the immunohistochemical reaction of calcitonin-gene-related peptide (CGRP) and type II collagen and also morphological changes of cartilage implants and cultured chondrocytes isolated from the articular and costal cartilages. The chondrocytes were isolated from the head of the femur and the 11th costal cartilage of the 6 months old rabbits. De novo implants were prepared from the chondrocytes cultured on the perichondrium by culturing isolated articular chondrocytes. Cultured chondrocytes and implants were evaluated by immunohistochemical staining of CGRP and type II collagen and electron microscopy. Articular chondrocytes maintained the typical phenotype in the 1st and 2nd subcultures, but the costal chondrocytes were transformed into fibroblast-like cells. The articular chondrocytes cultured on the perichondrium were more flattened and formed the cartilage. Most chondrocytes were no loss of type II collagen immunostaining by culturing. Implants replaced by the cultured articular chondrocytes were generally increased CGRP and decreased type II collagen immunoreaction. Electron microscopically the cultured articular chondrocytes had a large euchromatic nucleus, a few granules, and abundant vesicles. During culture, the nucleus became atropy and the cytoplasm contained many large vacuoles. The chondrocytes cultured on the perichondrium showed a lot of segmented rough endoplasmic reticulum and fine short microvilli. During culture, articular chondrocytes maintained typical phenotype and type II collagen reaction. The cultured articular chondrocytes had some organelles and euchromatic nucleus with prominent nucleolus. The chondrocytes cultured on the perichondrium showed active secretion of the matrix with small vesicles and well developed endoplasmic reticulum. The implanted articular chondrocytes showed the decrease of their organelles after secretion of the marix and became increased CGRP and decreased type II collagen immunoreaction.

Intracranial headaches, including migraines, are mediated by nociceptive activation of the trigeminal nucleus caudalis (TNC), but the precise mechanisms are poorly understood. We previously demonstrated that selective blockage of spinal sigma-1 receptors (Sig-1R) produces a prominent antinociceptive effect in several types of pain models. This study evaluates whether the Sig-1R antagonist (BD1047) has an antinociceptive effect on capsaicin (a potent C-fiber activator) induced headache models in rats. Intracisternal infusion of capsaicin evoked pain behavior (face grooming), which was significantly attenuated by BD1047 pretreatment. BD1047 consistently reduced capsaicin-induced Fos-like immunoreactivity (Fos-LI), a neuronal activator, in the TNC in a dose-dependent manner. Moreover, capsaicin-induced phosphorylation of N-methyl-D-aspartate receptor subunit 1 was reversed by BD1047 pretreatment in the TNC. These results indicate that the Sig-1R antagonist has an inhibitory effect on nociceptive activation of the TNC in the capsaicin-induced headache animal model.

Condylomata acuminata are benign tumors which are mostly venereally transmitted. Common sites were coronal sulcus, perisnal area and prepuce. Among 28 patients, 21 acuminate lesions and 10 papular lesions were found. Twenty eight human genital warts in Korean were analysed by Southern blot hybridization. Sequences related to HPV6/11 are found in 89.3%(25/28) of the condylomata. HPV16 DNA was not found at sll. Subtype of HPV was determined by the restriction pattern of DNA cleaved with PstI restriction enzyme in 7 cases. Six cases of HPV6a and one case of HPV6c are found. The above results suggest that most of condylomata acuminata are caused by HPV6 and HPV11 in Korea.

PURPOSE: An optimal treatment for Helicobacter pylori (H. pylori) infection in children has not yet been established. In this study, the efficacy and the tolerability of triple therapy with colloidal bismuth subcitrate (CBS), amoxicillin and metronidazole, were evaluated in comparison with dual therapy with CBS and amoxicllin. METHODS: Eighty-six children with H. pylori infection, aged 6 years to 14 years, were enrolled in this study. H. pylori infection was confirmed by endoscopic antral biopsy with an rapid urease test, culture and a modified Giemsa stain. The children were considered positive for H. pylori infection if culture was positive or if both modified Giemsa staining and CLO test were positive. The children were treated with one of the following three regimens. Dual therapy with CBS for 4 weeks and amoxicillin for 2 weeks (Group I. n=57: 1993.8-1995.1), Triple therapy with CBS for 4 weeks, amoxcillin for 2 weeks and metronidazole for 2 weeks (Group IIa. n=11: 1995.2-1995.7), and Triple therapy with CBS for 2 weeks, amoxicillin for 2 weeks and metronidazole for 2 weeks (Group IIb. n=18 : 1995. 8-1996. 6). A 50mg/kg/d dose of amoxcillin was aclministered, and that of CBS was 7-8mg/kg/d, and that of metronidazole was 20mg/kg/d. About one month after the cessation of treatment, eradication of H. pylori was evaluated with repeated endoscopic biopsy. RESULTS: H. pylori eradication rate was 61.4% (35/57) in Group I, 90.9% (10/11) in Group IIa, and in the absence of H. pylori 88.9% (16/18) of Group IIb was done by means of an urease test, culture and a modified Giemsa stain (P=0.012). The overall proportion of eradication of H. pylori infection was 89.7% (26/29) by triple therapy and 61.4% (35/57) by dual therapy (P=0.007). However, there was no statistically significant difference in eradication rate between the 2-week triple therapy (IIb) and the Denol 4-week triple therapy (IIa)(P=0.86). Side effects : All patients in three treatment groups were tolerated well with little and mild side effects (P=0.258). CONCLUSION: The 2-week triple therapy with CBS, amoxcillin, and metronidazole would be a highly effective and safe treatment regimen for H. pylori infection in children.

BACKGROUND: Mitral regurgitation is a valvular heart disease that produce complex hemodynamic alternations and myocardial dysfunction occurs subclinically, so result in a high incidence of left ventricular dysfunction that might affect postoperative result. In order to assess preoperative factors affecting the outcome of mitral valve replacement in patients with chronic mitral regurgitaion, we evaluated prognostic factors from preoperative clinical, laboratory, and echocardiographic findings in 71 patients with chronic mitral regurgitation who received mitral valve replacement. METHODS: From 1985 to 1994, 71 patients with chronic mitral regurgitation, who received mitral valve replacement, were included in this study. The patients were defined as group I who had improved symptom and / or decreased left ventricular end-diastolic dimension after operation, and group II who had persistent symptom and / or over 60mm of left ventricular end-diastolic dimension after operation. RESULTS: 1) In clinical findings, preoperative systolic blood pressure was higher in Group I patients(p<0.05). 2) Hemoglobin, serum creatinine, and blood urea nitrogen level were not significantly different in both groups. 3) In echocardigraphic findings, left atrial dimension, left ventricular end-systolic / end-diastolic dimension, and left ventricular volume index of Group II were much higher than those of Group I patients(p<0.05). 4) In the discriminant analysis, left ventricular end-diastolic dimension, age, NYHA functional class, and left ventricular mass index were defined as important prognostic factors. CONCLUSION: According to the above results, preoperative age, NYHA functional class are significant prognostic factors in clinical and laboratory findings. And left atrial dimension, left ventricular end-systolic and end-diastolic dimensions, left ventricular volume index, and left ventricular mass index are significant prognostic factors in echocardiographic findings.

BACKGROUND: To examine the influencing factors on patients' satisfaction in the emergency department(ED) far quality assurance. METHODS: Patients who visited to the ED were prospectively investigated from November 1 to December 31,1997. Authors developed questionnaire to investigate influencing factors on patients' satisfaction.4 Chi-square test and 115-REL 7.0 were applied far statistical analysis. RESULTS: Patients' satisfaction was significantly related to physical environment variables, accessibility variables, kindness of hospital personnel variables, and patient's trust for doctors variables. In path analysis, willingness for revisit was influenced by patients' satisfaction, accessibility, physical environment, patients' trust for doctors in order, and willingness for recommendation was influenced by accessibility, patients' satisfaction, and kindness of hospital personnel in order. CONCLUSIONS : The influencing factors on patients' satisfaction are physical environment, accessibility, kindness of hospital personnel, and patient's trust far doctors. Willingness far revisit and willingness far recommendation are influenced by patients' satisfaction. In spite of some limitations, the results of this study can be used as a baseline information for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the study of patients' satisfaction in the ED.

Attending conferences is important for doctors and residents in family medicine. Nevertheless, departments of family medicine at many hospitals find it difficult to hold regular conferences. Holding joint videoconferences between Family Medicine Departments of several hospitals through a videoconferencing system could solve this problem. Therefore, Family Medicine Departments of Seoul National University Hospital, Seoul National University Bundang Hospital, and Kangwon National University Hospital decided to hold regular joint videoconferences via a videoconferencing system. Eighty-one joint videoconferences were held from April 1 to October 29, 2010. PowerPoint slideshows were transferred to the other two locations in the same resolution as presenter's monitor. Image and voice of the speaker were transferred in real time and in acceptable quality. Joint videoconferences are feasible, satisfactory and useful for medical education, especially when individual family medicine departments are small and lack resources to hold face-to-face conferences. We expect that more family medicine departments will choose to participate in implementing similar joint videoconferencing systems in the future.

Cardiac manifestations of hypereosinophilic syndrome rarely include left ventricular thrombosis leading to peripheral emboli. And the cases of thrombectomy in patients with left ventricular thrombus and hypereosinophilic syndrome are extremely rare. Recently we experienced a 58-years-old woman with hypereosinophilic syndrome, the history of thalamic infarction and a huge thrombi in left ventricle. We report this case with literatures.

Endoscopic Variceal Ligation(EVL) was developed as an alternative to endoscopic injection sclerotherapy(EIS) for decreasing of complication rate. This new technique involves placement of small elastic O-rings around the variceal channels in the distal esophagus. To evaluate the efficacy of EVL for treatment of the acute bleeding esophagea1 varices and the efficacy of prophylactic EVL, we compared EVL in 88 patients who had recently bled from esophageal varices(Group 1) and prophylactic EVL in 45 patients with large size(Grade 2 or 3 or 4) and red color sign on endoscopic finding who had not previously had upper gastrointestinal bleeding(Group 2). Also, we compared prophylactic EVL group(Group 2) and control group(Group 3) who did not performed EVL. At the time of treatment 28.4%(25/88) of patients had active bleeding. They were all treated acutely with EVL and repeated treatment for the long-term goal of variceal eradication. Initial hemostatic efficacy of EVL for acute bleeding varices was 92%(23/25). Varices were eradicated or reduced to Grade 1 in 68%(17/2S). Early mortality rate within 2 weeks was 8%(2/25). Among patients who had eradicated or reduced to Grade 1 varices by repeated EVL sessions, over a mean follow-up of 11 months there was no difference between Group 1 and Group 2 in recurrent rate(49.1%(27/63) vs. 46.8% (15/32)), rebleeding rate(10.9'Yo (6/55) vs. 9.3% (3/32)), rebleeding interval(average 75 days vs, 83.6 days). There was significant difference between prophylactic EVL group and con- trol group in bleeding rate(9.3%(3/~32) vs. 43.7%(14/32))~(p<0.05). Three patients(6.6%) died in prophylactic EVL group, two from ligation site bleeding of esophageal varix, one from hepatic failure. In conclsion, EVL is an effective method for treatment of acute bleeding esophageal varices with repeated sessions. Although prophylactic EVL can be used to prevent bleeding by eradication with lower initial morbidity are necessary because of EVL-related complications.
