Objective : The aim of this study was to evaluate cross - reactivity between pollens in patients with strong skin reactivity to multiple pollens. METHODS: A pool of sera from 20 patients who showed strong skin responses( > or = 3+ ) to all three kinds of pollens ( tree, grass, and weed ) was used. Oak, ryegrass, mugwort, ragweed and hop Japanese pollens were chosen for the subject of study. The level and pattern of bound IgE to each pollen and cross - reactivity between pollens were investigated by ELISA and immunoblot experiments. RESULTS: In ELISA, the IgE of a pool of sera reacted to ryegrass and ragweed in 100%, to mugwort in 95%, to oak in 75%, and to hop Japanese in 65%, respectively. In inhibitory ELI - SA, more than 50% of bound IgE was mutually inhibited in oak vs ryegrass, oak vs mugwort, mugwort vs ryegrass and mugwort vs hop Japanese. In immunoblot, the IgE binding rate to major allergens of each pollen was 95% for hop Japanese, 75% for ragweed, 50% for ryegrass, 35% for mugwort, and 30% for oak, respectively. In inhibitory immunoblot, the mutually inhibited bound IgE could not be observed between major allergens of each pollen, but some minor allergens of oak pollen were mutually inhibited by ryegrass. CONCLUSION: Cross - reactivity between major allergens of oak, ryegrass, mugwort, ragweed and hop Japanese pollens was not observed at all, but some minor allergens of oak pollen cross-reacted with ryegrass and mugwort, and so did those of mugwort pollen with ryegrass and hop Japanese.

BACKGROUND: Although good clinical effects have been reported, immunotherapy with house dust mite ( HDM ) antigen - autologous specific antibody complex ( IC - IT ) is not yet accepted as an effective immunomodulating tool in HDM allergic diseases. We aimed to prove the clinical effect of IC - IT in HDM sensitized respiratory allergic subjects. Method : Six HDM sensitized respiratory allergic subjects were enrolled. Autologous D. farinae specific IgG was purified with DEAE ion exchange and affinity chromatography. After one year of IC - IT treatment the clinical effects were analyzed with symptom scores, methacholine PC20, ELISA assay of D. farinae specific antibodies and intradermal skin reactivity. Result : The rhinitis symptom score significantly improved after a one - year administration of IC - IT ( 1.23 +/- 0.30 vs. 0.37 +/- 0.15, p< 0.05), but no significant differences were found in asthma symptom score, intradermal skin reactivity to D. farinae and ELISA optic absorbances of D. farinae specific IgE, IgG, and IgG subclasses. Methacholine PC20 values improved in all 6 patients who were administered with IC - IT ( 0.35 vs. 1.66 mg/ml, p< 0.05 ). CONCLUSION: IC - IT may be efficient for management of HDM atopic asthma. Further studies are needed before clinical application of IC - IT in house dust mite atopic subjects.

PURPOSE: The aim of this study is to evaluate the T2 value of the articular cartilage of the glenohumeral joint in rotator cuff disease displayed on 3.0T MRI and to apply it in clinical practice. MATERIALS AND METHODS: This study involved sixty-two patients who underwent shoulder MRI containing T2 mapping. The mean T2 value was measured by placing a free hand ROI over the glenoid or humeral cartilage from the bone-cartilage interface to the articular surface on three consecutive, oblique coronal images. The drawn ROI was subsequently divided into superior and inferior segments. The assessed mean T2 values of the articular cartilage of the glenohumeral joint were compared and evaluated based on the degree of rotator cuff tear, the degree of fatty atrophy of the rotator cuff, and the acromiohumeral distance. RESULTS: ICC values between two readers indicated moderate or good reproducibility. The mean T2 value for the articular cartilage of the glenoid and humeral head cartilage failed to show any significant difference based on the degree of rotator cuff tear. However, the mean T2 values of articular cartilage, based on fatty atrophy, tended to be higher in fatty atrophy 3 or fatty atrophy 4 groups while some sub-regions displayed significantly higher mean T2 values. There was no correlation between the acromiohumeral distance and the mean T2 values of the articular cartilage of the glenoid and humeral head. CONCLUSION: T2 mapping of the glenohumeral joint failed to show any significant difference in quantitative analysis of the degenerative change of the articular cartilage based on the degree of rotator cuff tear. However, it also offers quantitative information on the degenerative change of cartilage of the glenohumeral joint in patients with rotator cuff tear and severe fatty atrophy of the rotator cuff.

OBJECTIVES: In this study, we compared anxiety, depression, and maternal-fetal attachment between high-risk pregnant women and normal pregnant women, and investigated whether there was a correlation between anxiety, depression, and maternal-fetal attachment in each group.METHODS: Two hundred and eleven pregnant women(118 high-risk pregnant women, 93 normal pregnant women) were recruited. All subjects were administered a sociodemographic and obstetric questionnaire, Stait Trait Anxiety Inventory-State(STAI-S), Beck Depression Inventory- II(BDI-II), and Maternal-Fetal Attachment Scale(MFAS).RESULTS: Total score of STAI-S in high-risk pregnant women was 13.704 point higher than that in normal pregnant women(95% CI=10.449–16.959, p<0.001). Also, total BDI-II score in high-risk pregnant women was 5.325 higher than that in normal pregnant women(95% CI=1.850–3.711, p<0.001). There was no significant difference between total MFAS score of normal pregnant women and that of high-risk pregnant women(t=1.594, p=0.112). There was a significant positive correlation between anxiety and depression in both normal(r=0.529, p<0.001) and high-risk(r=0.582, p<0.001) groups. In normal pregnant women, there was a significant negative correlation between anxiety and maternal-fetal attachment(r=−0.284, p=0.006).CONCLUSION: High-risk pregnant women experienced more anxiety and depression than normal pregnant women, and the maternal-fetal attachment was not significantly different between the two groups. The higher the level of anxiety of the pregnant women, the lower the degree of maternal-fetal attachment. Psychological support for dealing with the emotional problems of high-risk pregnant women and promoting maternal-fetal attachment is needed.

OBJECTIVE: To evaluate the clinical efficacy of a new air cleaning device (LG Electronics, Korea) equipped with electrostatic precipitator (EP) and photocatalytic plasma filter (PCP) in 24 respiratory allergic subjects. MATERIAL AND METHOD: Air cleaning conditioner and air cleaner were placed in living room and bedroom. Both EP and PCP (EP/PCP) filters were used for the first 4 weeks and for another 4 weeks, PCP without EP filter (PCP) was used. We measured symptom scores of asthma and rhinitis, peak expiratory flow rate (PEFR), serum eosinophil cataionic prote in? in ECP, Dermatophagoides farinae (DF) specific IgE and IgG in sera, concentrations of major allergens of DF in floor dust of living room, bedroom and in airborne dust. RESULTS: Both asthma and rhinitis symptom scores were significantly improved not only with EP/PCP filters but also with PCP filter. The morning PEFR was significantly improved with EP/PCP filters, but not with PCP filter. Frequency of salbutamol inhalation by air cleaner with EP/PCP filter tended to de crease(p=0.051), with no significant difference in serum ECP concentration. DF specific IgE significantly decreased at the 8th week with no differences in specific IgG. However, the mean Der f I levels in floor dust of bedroom (1, 128 vs. 374 ng/gm dust, p<0.01) and living room (1,516 vs 812 ng/gm dust, p<0.01) decreased, Der f1 in airborne dust measured only in 8 out of 22 subjects, and they decreased significantly with the trial of EP/PCP filter (172.2 pg/4.5m vs. 62.1 pg/4.5m, p<0.01). CONCLUSION: These results suggest that the EP/PCP air cleaner may be an effective tool for environmental control in respiratory allergic subjects.

The coronary arteries are also subject to congenital anomalies of both minor and major consequence. Hemodynamically significant primary anomalies of the coronary arteries are those which alter myocardial perfusion. There are four major types : coronary artery fistula, origin of the left voronary artery from the pulmonary artery, congenital coronary stenosis or atresia and origin of the left or right coronary artery from the opposite sinus of Valsalva with subsequent passage of the vessel between the aorta and right ventricular infundibulum. Minor anomlies are the variation of the origin of the coronary arteries from the aorta with normal distal circulation. We can see more coronary anomalies associated with congenital cardiac anomalies, probably representing a circulatory response to the primary intracardiac defect. We present a total of 76 cases of congenital coronary anomalies, reviewing 3946 cases of angiocardiography or selective coronary arteriography, performed during last 8 years at Sejong General Hospital.

OBJECTIVES: The purpose of this study is to investigate the clinical risk factors of emergency cesarean hysterectomy in patients with pregnancies complicated by placenta previa and whether the third trimester transvaginal ultrasonographic findings of placenta previa would predict emergency cesarean hysterectomy. MATERIALS AND METHODS: Between January 1995 and March 2005, we retrospectively reviewed the records and compared between patients with pregnancies complicated by placenta previa who underwent cesarean hysterectomy and patients with pregnancies complicated by placenta previa who did not undergo cesarean hysterectomy. RESULTS: There were 314 had placenta previa and 34 patients were performed cesarean hysterectomy (10.83%). There were significant differences on the basis of maternal age (31.53+/-4.41 vs 34.06+/-4.12, p<0.05), parity (0.81+/-0.70 vs 1.29+/-0.63, p<0.05) , the number of cesarean section (0.36+/-0.56 vs 0.91+/-0.75, p<0.05), previous history of placenta previa and presence of placenta accreta, but not on the basis of gestational age, the number of antenatal vaginal bleeding, the number of abortions and emergency operation between two groups. On the basis of third trimester transvaginal ultrasonographic findings, significant differences were found on the distances from the internal os of cervix (1.18+/-3.66 vs 2.67+/-2.94, p<0.05) and thickness of lower placental edge. However, the presence of lacuna in the lower placenta was not associated with emergency hysterectomy. CONCLUSIONS: Patients with placenta previa are at a higher risk of undergoing cesarean hysterectomy when they are associated with placenta accreta, thick lower placenta edge, and positively longer distance to the internal os of cervix. The other clinical factors such as maternal age, parity, the number of cesarean section and previous history of placenta previa might be associated the risk of cesarean hysterectomy.

Mercuric chloride, a model nephrotoxicant was used to elucidate time- and dose-dependent global gene expression changes associated with proximal tubular toxicity. Rat kidney cell lines NRK-52E cells were exposed for 2, 6 and 12 hours and with 3 different doses of mercuric chloride. Cell viability assay showed that mercuric chloride had toxic effects on NRK-52E cells causing 20% cell death (IC20) at 40micrometer concentration. We set this IC20 as high dose concentration and 1/5 and 1/25 concentration of LC20 were used as mid and low concentration, respectively. Analyses of microarray data revealed that 738 genes were differentially expressed (more than two-fold change and p<0.05) by low concentration of mercuric chloride at least one time point in NRK-52E cells. 317 and 2,499 genes were differentially expressed at mid and high concentration of mercuric chloride, respectively. These deregulated genes showed a primary involvement with protein trafficking (CAV2, CANX, CORO1B), detoxification (GSTs) and immunity and defense (HMOX1, NQO1). Several of these genes were previously reported to be up-regulated in proximal tubule cells treated with nephrotoxicants and might be aid in promoting the predictive biomarkers for nephrotoxicity.

OBJECTIVE: To investigate the value of ultrasound-guided tattooing localization (US-tattoo) using a charcoal suspension for breast lesions. MATERIALS AND METHODS: One hundred sixty-four nonpalpable breast lesions in 134 patients (mean age 47 years; range 30-74 years) were marked with a charcoal suspension under US guidance. The medical records associated with the US-tattoo, the pathology results and the follow-up US results were reviewed. RESULTS: The average size of the localized lesions was 1.0 cm. The procedure time was < 5 minutes (range, 2-10 minutes) per lesion. The US-tattoo was well tolerated in all cases. The only technical difficulty encountered was a needle tip blockage caused by a large charcoal particle (4.9%). The surgeon easily identified the tattoo with the exception one case. In addition, surgery could be safely delayed from one to 57 days after the making US-tattoo. The pathology result was benign in 108 cases, borderline in five, and malignant in 51. The excised specimen was < 4 cm in 76.6% (82/107) of the benign cases (mean; 2.7 cm). The pathologist could identify the mass around the tattoo and was able to make a specific diagnosis in 81.3% (87/107) of benign lesions. The only complication encountered was residual charcoal marking along the incision scar (3.6%). All follow-up US documented the removal of the lesions. CONCLUSION: An US-tattoo for nonpalpable breast lesions is a very simple and accurate method that can help surgeons design and schedule an open biopsy.

Cardiac lymphatic system in the remodeling after acute myocardial infarction (AMI) has been overlooked. We wanted to investigate the role of bone marrow-derived endothelial progenitor cells (EPCs) and their contribution to lymphatic distribution in myocardial remodeling after AMI. Mouse (C57bl/6J) MI models were created by ligation of the left anterior descending coronary artery and were treated with phosphate buffered saline (PBS) or EPCs. Real-time RT-PCR with 2- to 4-week myocardial tissue samples revealed that lymphangiogenetic factors such as vascular endothelial growth factor (VEGF)-C (8.5 fold, P < 0.05), VEGF-D (6.1 fold, P < 0.05), Lyve-1 (15 fold, P < 0.05), and Prox-1 (11 fold, P < 0.05) were expressed at significantly higher levels in the PBS group than the EPC group. The PBS group also showed a significantly higher density of lymphatic vessels in the peri-infarction area. Echocardiography showed that from 2 weeks after the treatment, left ventricle (LV) dimensions at both systole and diastole were significantly smaller in the EPC group than in the PBS group (P < 0.01) and LV fractional shortening was higher in the EPC group accordingly (P < 0.01). Lymphangiogenic markers increased in a mouse MI model. EPC transplantation decreased lymphangiogenesis and adverse ventricular remodeling after AMI. These novel findings suggest that new lymphatic vessels may be formed in severely damaged myocardium, and may be involved in adverse myocardial remodeling after AMI.
