This study was undertaken to improve the perceived value of halophytes and contribute to the activity of the local economy by analyzing the antioxidant activity and mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina that grow wild on the mud flats and coastal areas. The total phenolic compound content found in each order is as follows: Suaeda japonica (3.674∼5.989 mg TAE/g dry wt.), Tetragonia tetragonoides (2.515∼4.471 mg TAE/g dry wt.), and Spergularia marina (2.450∼4.067 mg TAE/g dry wt.); DPPH radical scavenging and ABTS cation radical scavenging activities were also recorded in the same order. In the case of minerals, Iron(Fe) was relatively high in Suaeda japonica (960.1∼1,346.7 mg/kg), Manganese(Mn) in Tetragonia tetragonoides (197.1∼574.8 mg/kg), and Zinc(Zn) was relatively high in Spergularia marina (63.19∼216.56 mg/kg). It was confirmed that the mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina was significantly higher than that of Chinese cabbage, lettuce, leek, and spinach.

Although many operative techniques have been developed to approach the parotid a gland, high recurrence rate and the occurrence of facial palsy still remain to be dilema in the parotidectomy. After reviewing 179 cases of parotid tumor retrospectively, including 8cases which utilized the peripheral approach, the authors came to the following conclusions. 1) The sex ratio is 1 : 1 and the mean age of occurrance was 43.1 for benign tumors and 43.4 for malignant tumors. 2) The histopathologic findings showed that 155 cases were benign tumors(86.5%)and 24 cases were malignant tumors(13.5%) 3) Among the benign tumors, the mixed tumor was the most common(126 cases, 81.2%)and in the malignant tumors the mucoepidermoid tumor was the most common(12 cases, 50%). 4) The truncal approach for parotidectomy was used in 171 cases, and the peripheral approach in 8 cases. 5) The peripheral approach is superior to the truncal approach because it can provide with a better surgical field ; the branches of facial nerve can be identified more superficially, and thus the liability of facial nerve injury is much lessened especially in large tumors. The peripheral approach also coincides with the embryologic development of parotid gland.

Ultrasound is very useful in evaluation of obstructive jaundice. We retrospectively evaluated the useful findings of ultrasonography in differentiating benign extrahepatic duct obstruction from malignant diseases. Among the 36 patients, 25 patients were benign extrahepatic obstruction and 11 patients were malignant obstruction. The shapes of extrahepatic dilatation were classified into fustiform, meniscus, and abrupt cut off by bowel gas. The diameter, length, and bile duct wall-interface were compared between benign and malignant groups and serum bilirubin and alkaline phosphatase were also compared between two groups retrospectively. The results were as follows. The most common form of extrahepatic dilatation was meniscus(10 of 26 patients, 38%) in benign obstruction, and fusiform(8 of 11 patients, 73%) in malignant obstruction. No significant difference was noted in diameter, length, serum bilirubin, and alkaline phosphatase between benign and malignant groups. Only one case showed decreased bile duct wall-interface in benign obstruction, but loss or decrease of bile duct wall-interface were 8 patients in malignant obstruction. The combined findings of fusiform dilatation and loss of bile duct wall-interface in ultrasonography will be helpful in differential diagnosis of malignant extrahepatic bile obstruction from benign conditions.

1989년 9월부터 1993년 7월까지 인제대학교 의과대학 상계백병원에서 실시한 위내시경 소견이 조기위암이며 내시경 직시하 생검결과 선암으로 판명되어, 근치적 위절제술을 시행받은 23명의 환자에서 임상적 특징을 알아보고, 문헌고찰과 함께 보고하는 바이다. The incidence and mortality rate of stomach cancer ranks well ahead of all malignancies in Korea. The prognosis is excellent in early gastric cancer of which the overall 5 years survival rate of 85∼95% is comparative with that of advanced gastric cancer of 15∼49%. So early detection with very sensitive mordality of gastroscope and surgery is the only premise to decrease the mortality rate of gastric cancer. This report deals with the clinical aspects of 23 cases of early gastric cancer, which were confirmed with histopathologic examination of resected stomach during the 4 years from September 1989 to July 1993 at Sanggye Paik hospital, Seoul, Korea. Out of 23 cases of early gastric cancer, 14 cases were male, 9 cases were female, and the male to female ratio was 1.6 : 1. The most common type of early gastric cancer was talc type(43.5%), IIc and its combined type comprised most of them(87.0%). The most prevalent sloe of lesion was gastric angle(43.5%) and the most common direction was lesser curvature(73.9%) 19 cases of 23(78.3%) were between 1∼3cm in size, and there was no statistical significance between the size of the lesion and lymph node metastasis. Of the 9 cases with mucosal lesion, there were 2 cases with lymph node metastasis(22.2%), but 7cases(50.0% ) of 14 cases with submucosal lesion presented lymph node metastasis. Diagnostic accuracy of endoscopy on detection of early gastric cancer was 17 cases(73.9%) of total 23 cases in our study. As with other report, histopathulogic examination of resected stomach revealed adenocarcinoma, tubular type as the most common type. Frequent complaint of patients with early gastric cancer was epigastric pain(65.2%), and duration of the symptom was less than 12 months in 17 cases(73.1%) of 23 patients with early gastric cancer.

Locally recurrent rectal cancer is a difficult clinical problem. Local recurrence following treatment for rectal cancer is a major cause of morbidity and mortality. The reported range of local recurrence rates following surgical treatment for rectal cancer has varied from 4% to 50%. We retrospectively reviewed the charts of 142 rectal cancer patients from January 1991 to December 1999. Analysis of patients factors included age, gender, type of surgery, and adjuvant therapy. Tumors were assessed for level, stage, and grade. Local recurrence and distant metastases were also documented. Variables influencing local recurrence in this group were identified and disease-free survival is determined. Of the 142 patients(74 males, 68 females; mean age 62.6 years), 137 consecutive patients operated on for rectal cancer and followed up to December 2000 (range 23-118months) were analyzed. Local recurrence rate was 18.3%. Age and sex of patients, type of surgery, location of tumor in the rectum, size, morphology and grading of the tumor were all unrelated to the event under investigation. At Cox regression, the Dukes stage and the postoperative radiotherapy were the only independent prognostic factors for local recurrence, and Dukes stage (Hazard ratio=2.89, p<0.001) and local recurrence (Hazard ratio=3.31, p<0.01) were the only independent factors associated with improved survival.

Granite weathered soil obtained from the cutting slope is divided into two sample materials of SM and SP on the basis of the Unified Soil Classification System (USCS), manufactured the model slope consisting of these, and the pore water pressure and the depth of seepage according to the inclination of the slope and the precipitation strength are measured. From the result of the experiment, the pore water pressure is increased in proportion to the precipitation strength, which is proportionally increased to the inclination of the slope and tends to be decreased when it meets the steep slope of more than 1:1.5. The speed of seepage to the slope in accordance with the precipitation is turned out fast when the inclination of the slope is gentle; according to the result of the Lumbs suggested formula, the actual speed of seepage is faster than the theoretical speed. The shear strength within the slope is decreased as the precipitation strength increases, and since it shows the minimum value at the inclination of the slope in 1:1.5, it can be said that the shear strength declines due to the' increase of the pore water pressure within the slope. Also the slope consisting of SP is faster in the seepage compared to that of SM: and the likelihood of the slope failure is a lot bigger as the shear strength greatly declines with the much increase of the pore water pressure.

성장기 환자를 다루는 경우가 많고 치료기간이 긴 교정치료는 성장과 발육에 대한 지식이 필수적이다. 현재 활용되고 있는 일반 체성 성장 관찰 도표는 현 시대의 성장기 환자의 체성 성장 추이를 적절히 반영하지 못하고 있는 바 이는 이용된 자료가 오래되었기 때문이다. 이에 따라 본 연구는 2004년 산업자원부 기술표준원에서 시행하고 대한인간공학회에서 주관한 2004년 제5차 한국인 인체치수조사사업보고서 자료를 토대로 현시성있고 유용한 성장 곡선 및 성장 속도 곡선을 제작하는 과정을 소개할 목적으로 시행되었다. 자료를 처리하고 재배열하는 과정을 통하여 자료의 변이를 사분위수를 기본 골격으로 하고 1, 5, 95, 99 백분위수를 추가하여 남녀별 키ㆍ몸무게 성장 곡선을 제작하였고 이와 아울러 기하 평균에 기초한 성장 속도 곡선도 제작하였다. 본 연구 결과 생성된 한국인 키 및 몸무게 신 평가표는 성장 발육의 지표로 이용될 수 있으며, 성장 발육과 관련, 교정환자와의 의사 소통에 도움이 될 수 있을 것으로 생각되었다. For orthodontic treatment of growing patients and those which involve long treatment times, knowledge of growth and development are essential. Data from the general growth observation chart being used at present does not reflect the growth transition of modem times. This is because these data are out of date. The present study, therefore, aims to introduce the process of producing a growth curve and growth rate curve based on data which represents a more accurate description of the present situation. The data used were from the 5th nationwide survey, SIZE KOREA 2004 study, carried out by the Technology and Standards Policy Division, Department of Technology and Standards Planning, Ministry of Commerce. Processing and rearranging produced data with variations divided into the three quartiles and the 1st, 5th, 95th and 99th percentiles were included to produce a growth observation chart according to sex, height and weight differences. In the same way, a growth rate curve based on the geometric mean value was produced. The resulting growth charts can be used as an index for growth and development, and used for better communication between the orthodontist, patients and parents.
