Purpose: To determine the prognostic role of muscle area and muscle radiation attenuation in the erector spinae (ES) and multifidus (MF) muscles in patients undergoing gastrectomy. Methods: Patients with stage I-III gastric cancer undergoing gastrectomy were retrospectively enrolled in this study. Clinicopathologic characteristics were collected and analyzed. Both paraspinal muscle index of ES/MF muscles (PMI_EM) and paraspinal muscle radiation attenuation in the same muscles (PMRA_EM) were analyzed at the 3rd lumbar level using axial computed tomographic images. Cox regression analysis was applied to estimate overall survival (OS) and disease-free survival (DFS). Results: There was only a weak correlation between PMI_EM and PMRA_EM (r= 0.28). Multivariate Cox regression revealed that PMRA_EM, but not PMI_EM, was an important determinant of survival. PMRA_EM along with age, tumor-node-metastasis (TNM) stage, perineural invasion, and serum albumin level were significant determinants of both OS and DFS that constituted Model 1. Harrell's concordance index and integrated area under receiver operating characteristic curve were greater for Model 1 than for Model 2 (consisting of the same covariates as Model 1 except PMRA_EM) or Model 3 (consisting of only TNM stage). Conclusion: PMRA_EM, but not PMIEM, was an important determinant of survival. Because there was only a weak correlation between PMI_EM and PMRA_EM in this study, it was presumed that they were mutually exclusive. Model 1 consisting of age, TNM stage, perineural invasion, serum albumin level, and PMRA_EM was greater than nested models (i.e., Model 2 or Model 3) in predicting survival outcomes.

Primary neoplasms of the ribs and sternum are rare. Most primary bony chest wall neoplasms are malignant, and chondrosarcoma is the most common malignancy in this location The etiology of chondrosarcoma is unknown. Definitive diagnosis of chondrosarcoma can only be made pathologically. The natural history of chest wall chondrosarcoma is one of slow growth and local recurrence. Most tumors of the sternum require wide resection and reconstruction procedures, with potentially serious postoperative problems. Advances in chest wall reconstruction primarily through refinement in muscle transposition and clarification of the functional anatomy and blood supply of trunk muscles, has resulted in a more aggressive resection of the these tumors . Recently we experienced a case with chondrosarcoma of the sternum. A 56 year-old man was admitted to our hospital due to painless, slowly enlarging mass at the left sternoclavicular junctional area. The chest radiograph strongly suggested an underlying cartilaginous neoplasm owing to the appearance of typical flocculent and curvilinear calcifications within the lesion. On CT of the chest, the tumor exhibited a scalloped or lobulated contour, hypodensity of the nonmineralized component in comparison to adjacent muscle, and characteristic stippled cartilaginous matrix mineralization, also typical for cartilaginous neoplasm. The patient underwent wide resection of the chest wall tumor include with a 2-3cm margin of normal tissue on all sides and the thoracic skeletal defect was reconstructed with polytetrafluoroethylene [Gore-Tex] soft-tissue patch. Soft tissue reconstructive procedure was done with the pectoralis major muscle transposition. The patient had an uneventful postoperative course and discharged without adjuvant treatment such as radiation and chemotherapy.

By a series of positional cloning, we successfully narrowed down the AM candidate region to approximately 1.2 Mbp on GGA2q including 7 functional genes. Subsequently, we identified WWP1 gene as the most likely AM candidate by sequence comparison. The amino acid sequence around the candidate mutation was highly conserved among tetrapods, suggesting that WWP1 is the causative gene of chicken muscular dystrophy. Transfection of mutated WWP1 gene into $C_2C_{12}$ myoblasts disrupted muscle differentiation process. The abnormal muscle differentiation is a characteristic of chicken muscular dystrophy, so we could demonstrate a part of phenotype of the disease. Furthermore, western blotting revealed that accumulation of caveolin-3 protein is limited in damaged muscle of muscular dystrophic chicken, suggesting caveolin-3 may be associated with the pathological change of the disease. We could conclude that WWP1 gene is the responsible one for chicken muscular dystrophy from these results, but the mechanism leading the onset should be clarified in the future. The information will contribute to the study of chicken muscular dystrophy and the corresponding human dystrophies.

Objectives : This study is to applied effectively to the acupuncture treatment for disorders following whiplash injuries. Methods : This study suggests five various ways and principtes of treating disorders following whiplash injuries by means of acupuncture. First principle is that acupuncture treatment is carried out on acupoint far from cervical spine at acute stage, on the other hand, Extraordinary Vessel and other acupuncture treatment such as five element acupuncture treatment is applied at chronic stage in order to control balance disoders due to cervical pathology. Second is acupuncture treatment will be performed in group of three part of Meridian System-Yangmyung, Taeyang, Soyang-according to cervical kinetic, its characteristic and location of pain. Third is acupuncture treatment could be performed on basis of theory of Eohyel-disorders and disturbance of blood circulation. Fourth is to decrease tension of SCM muscle, because disorders following whiplash injuries has much association to injury of CM muscle and is simillar to tension syndroms of SCM muscle. fifth is taping therapy could control and decrease disorders following whiplash injuries based on spiral balance taping theory. Conclusions : These results suggest that acupuncture treatment for disorders following whiplash injuries will significally decrease pain and control syndrom caused by cervical disorder.

Purpose In Sasang Constitution Medicine, persons are divided into four types such as Taeyangin, Taeumin, Soyangin and Soeumin according to their appearance, moral nature and characteristic of constitutional symptoms. In teenager group, diagnosis of constitution based on their appearance was so difficult that we adopted new diagnostic method which measures and compares body compositions. Methods 180 middle school students who live in Pusan were studied from 20th of March, 1999 to 20th of March, 2000. After practicing Questionnaire(I), QSCC(Questionnaire of Sasang Constitution) I , QSCCII, we have measured the height and body compositions with Inbody 3.0, five times. Results 1. The results of Sasang Constitution analysis showed 91 students were classified as Taeumin(50.3%), 75 as Soyangin(41.4%), 14 as Soeumin(7.7%), and 1 as Taeyangin(0.6%). 2. The level of total body water, muscle area, BMR(Basal Metabolic Rate), BCM(Body Cell Mass), and AMC(Arm Muscle Circumference) were increased during spring and summer. That of body weight, fat body weight, fat body weight ratio, waist hip ratio, and BMI(Body Mass Index were increased during fall and winter. 3. In Taeumin and Soyangin groups, the changed capacity of total body water, muscle area and BMR were increased with statistical significance. 4. Waist hip ratio of Soeumin group was reduced more than those of Taeumin, Soyangin groups with statistical significance.

A gene coding for triosephosphate isomerase (TPI) from a rat skeletal muscle cDNA library was cloned and its nucleotide sequence was determined. The 1, 348-bp cDNA clone contains 24 bp $5^I$ noncoding region, the entire 750 bp coding region corresponding to a protein of 249 amino acids, $547bp 3^I$ noncoding region and part of a poly(A) tail. It also contains a polyadenylation signal, AATAAA, starting from 17 bp upstream of the poly(A) tail. The calculated molecular weight of rat TPI is 27.8 kDa and the net charge is +4. The deduced amino acid sequence from rat TPI CDNA sequence has 93% and 94% homology with that of mouse and human clones, respectively. The amino acids at the residue of Asn12, Lys14, His96, Glu 166, His96, His101, Ala177, Tyr165, Glu13O, Tyr2O9, and Ser212 in catalytic site are completely identical, confirming that the functional residues in TPI proteins are highly conserved throughout evolution. The most profound characteristic of rat TPI enzyme, compared with other TPIs, is that there are five cysteine substitutions at the residue of 21, 27, 159, 195 and 204. A Glu123 instead of Gly was found in rabbit, rhesus, mouse and human sequences. Through the method of RT-PCR, the mRNA transcription level of TPI gene was found to be different among various tissues and was highest in muscle.

Certain malocclusion are associated with specific "facial type," and it is important for the clinician to classify the common facial characteristic of each patient. Because the reaction to treatment mechanics and the stability of the denture is depended upon the analysis of the facial pattern. Basically, there are 3 district facial types or patterns under which almost all malocclusion can be classified. 1. mesofacial is the most average growth. 2. brachyfacial which is a horizontal growth pattern has a week muscle, with dental arch, deep bite. 3. dolichofacial which is a vertical growth pattern has a strong muscle, narrow dental arch, open bite. Brachyfacial pattern show a resistant to mandibular rotation during treatment can accept a more protrusive denture and are prominantly nonextraction, whereas dolichofacial patterns tend to open during treatment require a more retracted denture in order to assure post-treatment stability. Brachyfacial pattern would better treat to use extrusive force system, whereas dolichofacial pattern treat to use intrusive force system with head gear and intermaxillary elastics.

Dermatomyositis is a rare and idiopathic inflammatory myopathy with a characteristic cutaneous manifestation. A 62-year-old female complained of polyarthralgia that lasted for many years. She was diagnosed with hypomyopathic dermatomyositis by the typical skin rash associated with dermatomyositis but without muscle involvement such as muscle weakness, elevated level of creatinine phosphokinase and aldolase. Her symptoms improved with treatment of hydroxychloroquine and prednisolone. We experienced a case of hypomyopathic dermatomyositis on 62-year-old female patient and report with review of literatures.

Asthma is characterized by a chronic inflammatory disorder of the airways that leads to tissue injury and subsequent structural changes collectively called airway remodelling. Characteristic changes of airway remodelling in asthma include goblet cell hyperplasia, deposition of collagens in the basement membrane, increased number and size of microvessels, hypertrophy and hyperplasia of airway smooth muscle, and hypertrophy of submucosal glands. Apart from inflammatory cells, such as eosinophils, activated T cells, mast cells and macrophages, structural tissue cells such as epithelial cells, fibroblasts and smooth muscle cells can also play an important effector role through the release of a variety of mediators, cytokines, chemokines, and growth factors. Through a variety of inflammatory mediators, epithelial and mesenchymal cells cause persistence of the inflammatory infiltrate and induce airway structural remodelling. The end result of chronic airway inflammation and remodelling is an increased thickness of the airway wall, leading to a increased the bronchial hyperresponsiveness and fixed declined lung function.
