This study was carried out to evaluate the immunohistochemical expressions of p53, E-cadherin, and nm23 proteins in 114 cases of metastatic carcinoma of the neck lymph node (MTLNCA) and corresponding primary carcinoma (PRCA). The positive expressions of p53, E-cadherin, and nm23 proteins were 62.3%, 58.8% and 64.0%, respectively in PRCA, and 40.4%, 38.6%, and 43.9%, respectively in MTLNCA with significant down-regulation from PRCA to MTLNCA (p<0.05). The down-regulation was correlated with female gender, moderate and poor differentiation, and adenocarcinoma in p53 protein, female gender, respiratory and gastrointestinal carcinoma in E-cadherin protein, and female gender, respiratory carcinoma, moderate differentiation, and squamous cell carcinoma in nm23 protein (p<0.05). There was no significant relationship among expressions of p53, E-cadherin, and nm23 proteins (p<0.05). In conclusion, these results suggest that the expressions of p53, E-cadherin, and nm23 proteins seem to be down-regulated from PRCA to MTLNCA and this down-regulation may play a role in invasion and metastasis.

BACKGROUND: The implementation of health care delivery system(HCDS) in 1989 affected the visit pattern of tertiary care hospital. In this study we analyzed the effect of implementation of HCDS in a university hospital. METHODS: We analyzed the yearbook of a university hospital from 1986 to 1992. The clinical departments were divided into three groups of medical departments, surgical departments with application of HCDS and clinical departments without application of HCDS. RESULTS: The total outpatient visits increased after implementation of HCDS. The new outpatient visits decreased after implementation in the medical departments and surgical departments but re-visit patients increased in all clinical departments. The number of emergent patients increased at year 1889, but decreased in 1990, then little changed. Admission rate via emergency room decreased in surgical departments and clinical departments without application of HCDS. The patient from Pusan in which hospital is located was little changed but patients that from other areas increased. So the proportion of patients from Pusan decreased, and from other regions increased. The visit of patients with self pay decreased, but patients with medical insurance increased. CONCLUSIONS: In spite of increased total outpatient visits, the new outpatient visits and patient visits from near place decreased through implementation of HCDS. The new outpatient visits decreased in the medical departments and surgical departments in clinical departments with application of HCDS, but the new outpatient visits increased in clinical departments without application of HCDS.

BACKGROUND: Diabetes mellitus is a heterogeneous group of disorders characterized by high serum glucose levels and by disturbances of carbohydrate and lipid metabolism. There are many cutaneous signs of this common endocrinopathy, such as nercobiosis lipoidica diabeticorum, diabetic bullosis, shin spot, diabetic pruritus, etc. OBJECTIVE: In this study, we investigated whether extracellular matrix gene expression in cultured skin fibroblast is influenced by insulin and Insulin-like growth factor-I(IGF-I). METHOD: Total RNA was isolated from insulin or IGF-I treated human skin fibroblasts. The Northern blot and slot-blot hybridization were then conducted. RESULTS: The mRNA levels of pro α1(I) collagen, pro α1(I11) collagen, fibronectin in insulin and IGF-I treated normal skin fibroblasts increased compared with untreated normal skin fibroblasts. CONCLUSION: Our results show that insulin and IGF-I stimulate collagen formation in normal skin fibroblast at physiological concentrations. Therefore, these demonstrate that insulin can modulate the expression of extracellular matrix gene.

A 55-year-old female experienced acute left shoulder pain without specific trauma. Radiography showed calcific deposits in the inferior part of the glenoid fossa. Magnetic resonance arthrography showed calcific deposits in the origin of the long head of triceps brachii muscle. Conservative treatment failed to resolve the symptoms; therefore, arthroscopic surgery was performed. The patient experienced immediate and dramatic pain relief, and normal shoulder motion was demonstrated 1 year after surgery. In conclusion, although rare, calcific tendinitis of the triceps brachii muscle, which causes shoulder pain, should be included in the differential diagnosis of acute shoulder pain. Arthroscopic surgery is a treatment option for chronic cases and those resistant to conservative treatment.

Nowdays steroid injection into the epidural space is increasing gradually by pain clinic physician in order to control of low back and radiculating pain. But, there are a few reports about the effect of methylprednisolone that is injected into the epidural space on the plasma cortisol levels. So we undertook to determine the effect of epidural methylprednisolone acetate(Depomedrol) on the hypothalamus-pituitaryadrenal axis by checking plamsa cortisol levels. 9 patients were given 80 mg of methylprednisolone acetate and 10 ml of 0.25% bupicaine epidurally 3 times of injection at weekly intervals and checked the plasma cortisol levels of 1 hour before and after each injection respectively. The levels of plasma cortisol were also checked at first and 4th week after the last injection. The results are as follows: The baseline plasma cortisol level is 11.21+/-6.38mg%. The plasma cortisol levels of 1 hour before and after 2nd injection are 3.94+/-5.38 and 4.11+/-7.10mg%. The plasma cortisol levels of 1 hour before and after 3rd injection are 2.01+/-1.33 and 2.90+/-4.31mg%. The palsma cortisol level of 1st week after the last injection is 1.76+/-1.03mg%. The plasma cortisol level of 4th week after the last injection is 7.45+/-2.38mg%.

PURPOSE: This study is for the evaluation of low tesla(0.064T) MR imaging diagnostic accuracy in the internal derangement of the knee. MATERIALS AND METHODS: We retrospectively analysed the MR images of 36 injured knees of 35 patients. The presence of tear was determined by arthroscopy or surgery in all cases. RESULTS: The sensitivity, specificity, accuracy, positive predictive value, negative predictive value of low tesla MRI for the diagnosis of anterior cruciate ligament injury were 83%, 88%, 86%, 77%, 91%, for the posterior cruciate ligament 75%, 95%, 86%, 92%, 83%, for the medial collateral ligament 83%, 96%, 92%, 91%, 92%, for the lateral collateral ligament 67%, 97%, 94%, 67%, 97%, for the menisci 75%, 93%, 89%, 75%, 93%. CONCLUSION: The low tesla MRI is an accurate method in detection and evaluation of the internal derangement of the knee.
