OBJECTIVE: SCC-Ag(Squamous Cell Carcinoma Antigen) is a tumor marker for patients with squamous cell carcinoma of the uterine cervix. It has shown that the SCC-Ag was well related with the response of cancer therapy and course of cervical cancer. The aim of this study is to investigate whether the presence of pelvic lymph node metstasis can be predicted by the measurement of the preoperative SCC-Ag levels in the patients with early staged squamous cell carcinoma of cervix. METHODS: The preoperative serum SCC-Ag levels were measured in 45 patients with stage I-II squamous cell carcinoma of cervix undergoing radical hysterectomy from September 1995 to December 1997. The serum SCC-Ag levels were analyzed for the clinicopathologic characteristics and other prognostic factors using univariate and multivariate analysis. RESULTS: The serum SCC-Ag levels of the patients exhibited pelvic lymph node metastasis were above 4.8ng/ml. An elevated preoperative serum SCC-Ag level, and tumor size were independent predictors for the presence of lymph node metastasis(p<0.01). CONCLUSION: The determination of the preoperative serum SCC-Ag levels provides a new prognostic factor in early staged cervical cancer.

BACKGROUND: The purpose of this study was to investigate the mechanism of endothelium-dependent and independent responses to endothelins (ETs) in porcine coronary artery. METHODS: The vascular rings of left anterior descending artery or left circumflex artery from 7 pigs were suspended in conventional organ chambers for the measurement of isometric force. To evaluate relaxation responses, vascular rings with endothelium were exposed to ET-1 and ET-3. To evaluate contraction responses, vascular rings with and without endothelium were exposed to ET-1 and ET-3 in the presence or absence of BQ 123 (ET(A) receptor antagonist) or TAK-044 (ET(A) and ET(B) receptor antagonist). RESULTS: Transient relaxation responses of vascular rings occurred after exposure of ET-1 and ET-3. These transient responses disappeared after preincubation with N-nitro-L arginine. There was an increased contractions of vascular rings according to increasing concentration of ET-1 and ET-3. The initial responses were enhanced in vascular rings without endothelium in ET-1 and ET-3. In vascular rings with endothelium, the contraction responses were more reduced in vascular rings with preincubation of BQ 123 than in vascular rings without BQ 123 in ET-1. In vascular rings without endothelium, the contraction responses were more reduced in vascular rings with preincubation of TAK-044 than in vascular rings without TAK-044 in ET-1. CONCLUSION: ET(B) receptor on the endothelium might mediate the transient vasodilator responses to ET-1 and ET-3 through release of nitric oxide in porcine coronary artery. ET(A) and ET(B) receptor on vascular smooth muscle cells might mediate vasoconstrictor responses to ETs.

In recent years, the Korean Medical Association has undertaken the feat of establishing the Korean Standard Terminology of Medical Procedures with the dedicated help of 32 medical academic societies. However, because the project is being conducted by several different circles, it has yet to see a clear system of classification. This thesis, therefore, proposes the three principles of scientific properties, usefulness and ideology as the basis for classification system and has developed the Classification System of Medical Procedures in Korea upon their foundation. The methodology and organization of this thesis as follows. First, by adopting scientific classification system of Feinstein(1988), an analysis of the classification systems of the medical procedures in the United States, Japan, Taiwan, Who Was carried out to reveal the framework and the basic principles in each system. Second, the direction of classification system has been constructed by applying the normative principle of medical field in order to show the future direction of the medical field and realize its ideology. Third, a finalized framework for the classification system will be presented as based on the direction of classification system. Of the three basis principles mentioned above, the analysis on the principles of usefulness was left out of this thesis due to the difficulty of establishing specific standards of analysis. The results of the study are as follows. The overall structure of the thesis is aimed at showing the 'Prevention-Therapy-Rehabilitation' quality of comprehensive health care and consists of six chapters; I. Prevention and Health Promotion. II. Evaluation and Management . III. Diagnostic Procedures. IV. Endoscopy. V. Therapeutic Procedures. VI. Rehabilitation. Chapter three Diagnostic Procedures is divided into four parts; Functional Diagnosis, Visual Diagnosis, Pathological Diagnosis, Biopsy and Sampling. Chapter five Therapeutic Procedures is divided into Psychiatry, Non-Invasive Therapy, Invasive Therapy, Anaesthesia and Radiation Oncology. Of these sub-divisions, Functional Diagnosis, Biopsy and Sampling, Endoscopy and Invasive Therapy employs the anatomical system of classification. On the other hand, Visual Diagnosis, Pathological Diagnosis, Anesthesia and Diagnostic Radiology, namely those divisions in which there is little or no overlapping in services with other divisions, used the classification system of its own division. The classification system introduced in this thesis can be further supplemented through the use of the cluster analysis by incorporating the advice and assistance of other specialists.

Clinical observation was performed on 23 children with Guillain-Barre syndrome which were hospitalized at the Pediatric ward of Han Yang University Hospital, from July 1975 through May 1991.@ES The results were as follows: 1) The ratio of male patient to female was 2.8:1 and 47.8% of total GBS patients were between the ages 1 to 5 years. 2) The highest seasonal incidence of GBS was seen in summer and there was no significant variation of GBS annually.3) Preceding illness of GBS was found in 60% of the total patients, and upper respiratory infection was the most common (65%). 4) Muscular paralysis or weakness in extremities was the most common chief complaints on admission, and repiratory difficulty, vomiting, diarrhea, swallowing difficulty and myalgia were followed. 5) The sites of paralysis on admission were upper and lower extremities in 14 GBS patients (60.8%), lower extremities in 7 GBS patints (34.8%) and respiratory muscle in 4 GBS patints (17.3%), respectively. 6) The protein content of cerebrospinal fluid was elevated in 18 GBS patients of total (78.3%) on admission and remnant 5 GBS patients showed increased protein later. 7) There was a tendency that recovery time in 5 GBS patients with muscular fibrillation on E.M.G. was longer than in 4 GBS patients without muscular fibrillation. We thought further studies on critical evaluation and better treatment for GBS were needed.

PURPOSE: The purpose of this study is to evaluate the findings of magnetic resonance imaging(MRI) of posterior fossa hemangioblastoma and usefulness of contrast enhancement with Gd-DTPA. MATERIALS AND METHODS: Seven patients with posterior fossa hemangioblastoma were studied with both pre- and post-enhanced MRI. The MR images were reviewed regarding the location, size, signal intensities of cysts and mural nodules, and their contrast enhancement pattern. RESULTS: Five tumors were located in cerebellar hemisphere, one in vermis, and one in posterior part of medulla. One patient with von HippeI-Lindau disease had a medullary hemangioblastoma with multiple pancreatic cysts. In 6 cases, the major portion of the tumor was cysts and had small mulkal nodules. The solid portion was relatiely lange in one case, cemprising half of the tumor Cysts were oval shaped and their sizes were 3--6.7cm in diameter. In five cases(71%), septations were noted within the cysts. Cysts were isointense or slightly hyperintense on Tl-weighted image and hyperintense on T2-weighted image compared with cerebrospinal fluid. Mural nodules were oval or rounded appearance in five cases and flattened appearance in two, and their size was 0.5--2.5cm in diameter. Mural nodules were isointense to gray matter. They were detected in five cases on Tl-weighted images and one case on T2-weighted images. In two cases, vascular signal void area was noted in mural nodules. On contrast-enhanced Tl-weighted images, all mural nodules were intensely enhanced. CONCLUSION: MRI proved to be a good diagnostic method to detect and characterize posterior fossa hemangioblastoma. The most common finding is Cystic posterior fossa lesion with enhancing mural nodule. Contrast enhancement is essential for specific diagnosis.
