Endotracheal intubation is the most useful and safe method to keep airway in general anesthesia. But there are many problems such as severe cardiovascular changes, difficult intubation, larygospasm and tracheal stenosis in using laryngoscope and tracheal intubation. Laryngeal mask airway(LMA) is new method to keep airway and has many advantages such as easy insertion, decreasing cardiovascular changes, insertion without muscle relaxant, decreasing damage of pharynx and laynx and useful in difficult intubation. Cinical study of LMA No. 2 was done in 30 children weighted between 8.9-26 kg, about cardiovascular changes, volume and pressure changes of inflaton cuff, problems and complications during insertion and maintaining of LMA. The result, were follows I) The average time taken to insert the LMA was 7.4+/-3.3 second and 12 case were correct placement at the second attempt to use laryngoscope. 2) The volume of inflation cuff without air leak during positive pressure ventilation with 15cmH2O of peak airway pressure was 7.9+/-0.5ml and inflation cuff pressure at insertion was 40.1+/-15.9 mmHg and increased(p<0.05) continously. 3) Mean arterial pressure was increased(p<0.05) compared with preinduction value and normalize within a minute. Heart rate was incresed(p<0.05) compared with preinduction value and increase was sustained. 4) There were no complications except 1 case of gastric disteesion.

PURPOSE: The usual technique of temporomandibular joint (TMJ) reduction, recommended by most emergency medicine textbooks, consists of downward forces applied to the mandible. However, it has been the authors' experience that conscious sedation and significant force is required to achieve reduction. For that reason, we designed a new method of TMJ reduction. The purpose of our study is to introduce the new method of TMJ reduction and to compare the traditional method with the new method. METHODS: We performed a prospective, randomized trial with 52 patients who were diagnosed as having a TMJ dislocation. The patients were divided into two groups: the group treated with the traditional method (25 cases) and treated with the new method (27cases). Patients with histories of trauma or inflammatory signs were excluded from this study. The new method is an extraoral approach in which the operator applies the coronoid process on the face in the posteroinferior direction. RESULTS: Age, sex, and history of TMJ dislocation showed no statistical differences between the two groups. Reduction of the TMJ dislocation was achieved in 15 (60.0%) of the traditional method group and in 25 (92.6%) of the new method group (p=0.005). The means of the reduction time were 11.8+/-6.2 sec in the traditional method group and 6.6 +/- 3.3 sec in the new method group (p=0.007). CONCLUSION: The new method was an effective treatment for TMJ dislocation without any sedations. I had a higher success rate and a shorter reduction time than traditional method.

BACKGROUND: Many autopsy studies have shown that the extent of extracranial carotid and coronary artherosclerosis is correlated and B-mode ultrasonographic intima-media thickness(IMT) and histologic IMT have been good correlation. In recent years. as it has been reported that IMT of carotid artery had something to do with risk factors of atherosclerosis and occurrence of coronary artery disease, in this study, we tried to investigate if the grade of atherosclerosis in B-mode ultrasonography of carotid artery could predict coronary artery disease and have something to do with the severity of coronary artery disease. METHODS: We classified the patients who were examined coronary angiography into control group without significant(>50%) stenosis(11 patients) and coronary artery disease(CAD) group(45 patients) according to the existence of significant stenosis, and we subdivided CAD group into single vessel disease(SVD) group(25 patients) and multivessel disease(MVD) group(20 patients). Practicing B-mode ultrasonography of common carotid artery(CCA), carotid artery bifurcation(BIF) and internal carotid artery(ICA), we measured IMT and IMT/L(lumen diameter) of each segment. Adding all values of each segment, we got mean aggregated IMT and mean aggregated IMT/L. RESULTS: 1) As IMT of left BIF in both six segments, control group was 0.55+/-0.16mm, SVD group was 0.71+/-0.36mm and MVD group was 1.02+/-0.61mm. So compared with control group and SVD, MVD group were significantly thick. As IMT/L, control group was 0.07+/-0.02, SVD group 0.08+/-0.05 and MVD group was 0.13+/-0.08. So compared with control group and SVD, MVD group was ignificantly high. 2)IMT of BIF in three segments, control group was 0.59+/-0.16mm, CAD group was 0.82+/-0.47mm and MVD group was 0.90+/-0.54mm. So compared with control group and CAD, MVD group were significantly thick. Also as IMT/L of BIF, compared with control group(0.07+/-0.02) and CAD(0.10+/-0.06), MVD(0.11+/-0.07) group was high.= 3) As mean aggregated IMT, control group was 0.57+/-0.34mm, CAD group was 0.69+/-0.45mm, SVD group was 0.63+/-0.12mm and MVD group was 0.74+/-0.21mm. So CAD group was thicker than control group and MVD group was thicker than SVD group. As mean aggregated IMT/L, control group was 0.07+/-0.03, CAD group was 0.10+/-0.05, SVD group was 0.09+/-0.01 and MVD group was 0.11+/-0.03. So CAD group was higher than control group and MVD group was higher than SVD group. CONCLUSION: These data support use of the mean aggregated B-mode ultrasonographic IMT and IMT/L in carotid bifurcation for correlation with the status of coronary atherosclerosis.

The purpose of the present study was to determine the preventive effects of combined interventional trial of fish oil treatment and exercise training on insulin resistance of skeletal muscle in high-fat fed rats. Male Wistar rats were randomly divided into chow diet (CD), high-fat diet (HF), high-fat diet with fish oil (FO), high-fat diet with exercise training (EX), and FO+EX groups. The rats in control group were fed chow diet containing, as percents of calories, 58.9% carbohydrate, 12.4% fat, and 28.7% protein. High-fat diet provided 32% energy as lard, 18% as corn oil, 27% as carbohydrate and 23% as casein. The fish oil diet had the same composition as the high fat diet except that 100 g menhaden oil was substituted for corn oil. Insulin sensitivity was assessed by in vitro glucose transport in the soleus muscle after diet treatment and treadmill running for 4 weeks. While the FO or EX only partially prevented insulin resistance on glucose transport and visceral obesity induced by high-fat diet, these interventions completely corrected hyperinsulinemia and hyperglycemia from the high-fat diet. The rats in the FO+EX showed normalized insulin action on glucose transport, plasma chemicals and visceral fat mass. Insulin-mediated glucose transport was negatively associated with total visceral fat mass (r=-0.734; p<0.000), plasma triglyceride (r=-0.403; p<0.05) and lepin (r=-0.583; p<0.001) concentrations with significance. Multiple stepwise regression analysis showed that only total visceral fat mass was independently associated with insulin-mediated glucose transport (r=-0.668; p<0.000). In conclusion, combined interventional trial of FO+EX recovered insulin resistance on glucose transport of skeletal muscle induced by high-fat diet. Visceral fat mass might be more important factor than plasma TG and leptin to induce insulin resistance on glucose transport of skeletal muscle in high-fat fed rats.

PURPOSE: Currently the most widely used method of measuring IgG concentration is the method employing ELISA. This method has an advantage to detect smaller quantities than other standard methods, but in certain cases, consistent results cannot be obtained, thus impairing reliable data analysis. In this study, we attempt to determine the advantages in data analysis offered by the new method developed by Binding Site Ltd. (England) that employs a nephelometry. METHODS: 20 healthy subjects were studied from each of the following age groups : neonates, 1-4 months old, 5-10 months old, 11-24 months old, and 2-5 years old children. Serum IgG and IgG subclass concentrations were measured by nephelometry (Gehring Nephelometer Analyzer II, Germany) using Human IgG subclass, Liquid reagents BNII kit (Binding Site Ltd., England). RESULTS: 1) The r values for the standard curves of IgG, IgG1, IgG2, IgG3, IgG4 concentrations were 0.991, 0.997, 0.980, 0.973, 0.997, respectively. 2) IgG, IgG3, and IgG4 concentrations were lowest at the age of 5-10 months and increased to normal adult levels at 2-5 years of age. 3) IgG1 and IgG2 were lowest at the age of 1-4 months and increased to normal adult levels at 2-5 years of age. CONCLUSION: The method employing nephelometry for measuring serum IgG & IgG subclasses concentration is not as sensitive as ELISA in detecting the lower concentrations. However, our studies indicate that it presents the advantage of better quality control in measuring values in the average range.

We herein report two patients with epidermolysis bullosa acquisita(EBA), who had showed the atypical clinical features. A 25-year-old male presented with multiple pruritic vesicles, erosion and crusts which occurred more severely on the face than any other sites of the skin and healed with atrophic scar formation. Histopathologically, there was a subepidermal neutrophilic blister with moderate perivascular lymphohistiocytic infiltrates in the dermis, and the diagnosis of EBA was confirmed by means of direct immunofluorescence and salt-split direct immunofluorescence test performed on the perilesional skin. The other patient was a 24-year-old female who had had multiple painful ulcerative lesions on the oral mucosa for 4 months. After then, vesicles and bullae developed to progressively generalize to the anterior neck, chest and lower leg. Histolopathologic examination of peribullous skin showed a subepidermal bulla with neutrophils and eosinophils. The salt-split skin direct immunofluence test showed IgG and IgM binding to the dermal side only. We diagnosed this patient as nonscarring inflammatory EBA. Both patients were treated with prednisolone, colchicine, and dapsone resulting in clinical improvement, but their skin lesions recurred several months after discontinuing medication.

Although bladder transitional cell carcinoma (TCC) is common, the underlying molecular events remain ill-defined. So we attempted to define the role of tumor suppressor genes in the pathogenesis of bladder tumor through a molecular genetic study. For 15 bladder TCC (6 gradeII, 1 gradeIII, and 8 grade IV), we performed the restriction fragment length polymorphism (RFLP) analysis for 6 loci of suspected or established tumor suppressor regions (3p21, 3p24-25, llp15, 13q14, and 17p13). Our data confirm that allelic losses are highly common in bladder tumors. We found that alleles from each of the four chromosomal arms tested were lost in most of the tumors. Reduction of allele occured at 3p21 (13%), 3p24~25 (50%), and 13q14 (38%). However, the greatest frequency of allelic loss was seen for 17p 13 (100% of informative cases) and llp15.5 (87% informative cases). Severe allelic losses of chromosome 17p and pADJ762 on lip were seen only in grade IV, not in grade II. Amplification of 3p21 was seen six out of eight. Amplification of 3p21 has not been previously observed on the other study. Addition to this, we observe the loss of H-ras allele on 11p in one case which was associated with duplication of the retained allele as was demonstrated in Wilms'tumors. The results of out study suggest that deletions of pADJ762 on chromosome 11p and 17p13 occur in high grade bladder tumor and may contribute to the progression of this disease. But, there was no apparent correlation between tumor grade and the loss of 3p or 13q14 alleles although they had some deletions. The role of these genetic alterations in the prognosis of bladder transitional cell carcinoma will require additional follow-up and further studies.
