잣나무 Fibril 경사각의 (傾斜角) 변이에 관한 연구

이원용,권진헌 ( Won Young Lee,Jin Heon Kweon ) 한국산림과학회 1980 한국산림과학회지 Vol.46 No.1

The purpose of this study was carried out to examine the systematic trends in fibril angle which existed within the trunk of Pinus koraiensis Sieb. et Zucc. In 1937 I.W.Bailey reported that crystalline aggregates of iodine may be induced to form within the elongated interstices of the cellulose matrix of the secondary wall, and that these elongated crystals are oriented parallel to the long axis of the fibrils of cellulose. The authors tried a simple method (Yaichi kobayashi method) of demonstrating the fibrillar orientation in lignified walls in which Schulze`s reagent was used. The results were summarized as follows. 1. Fibril angles were greater for earlywood (avg. 23.38°) than for latewood (avg. 17.85°). 2. The average fibril angles of consecutive rings decreased consistently and markedly from pith to bark. 3. Differences of the fibril angle between in springwood and in summerwood were greater in corewood than in middle or outerwood.

식도협착증 환자에서 발생한 식도천공의 비개흉적 식도적출술에 의한 치험 2례

When the perforation of intrathoracic esophagus occurs in the presence of preexisting esophageal stricture, aggressive and definitive therapy often provides the only chance for patient salvage. Two adults suffering from intrathoracic esophageal perforation with underlying stricture underwent transhiatal esophagectomy. The perforations were due to esophageal instrumentation. Restoration of alimentary continuity with a primary cervical pharyngogastric anastomosis was carried out in one patient. Another patient underwent a cervical esophagostomy and had a subsequent colonic interposition 3 months later.

Supravavular aortic stenosis is a congenital narrowing of the ascending aorta just distal to the level of the origins of the coronary arteries, that may be localized or diffuse. Five patients with supravalvular aortic stenosis were operated upon between July, 1986 arid June, 1990. Four of these patients were William`s syndrome [mental retardation, elfin face], and one was isolated supravalvular aortic stenosis. Preoperative diagnosis of the supravalvular aortic stenosis was made by left side cardiac catheterization and angiocardiography. There are three types of supravalvular aortic stenosis such as membranous, hourglass and hypoplastic. Four of our patients were of hourglass type, and one was hypoplastic type. Patch aortoplasty was performed in all cases. Preoperative systolic gradients ranged from 45 to 1SO mmHg [average 102.6 mmHg]: postoperative gradients ranged from 0 to 75 mmHg [average 39 mmHg]. The patient of hypoplastic type has been suffered from mild exercise intolerance even after the operation, and the postoperative echocardiography revealed the systolic gradient of 100 mmHg [preoperative 180 mmHg]. The results of surgery for hourglass type were excellent. But the patient with hypoplastic form would be benefited from some modifications of the operation.

이원용,최준영,서경필,Lee, Won-Yong,Choe, Jun-Yeong,Seo, Gyeong-Pil 대한흉부심장혈관외과학회 1991 Journal of Chest Surgery (J Chest Surg) Vol.24 No.3

Intra-aortic balloon pump [IABP] was applied to 12 patients between July, 1987, and September, 1990. The 12 patients included 8 who were assisted with IABP intraoperatively; 4 patients used IABP postoperatively. 8 patients could not be withdrawn from cardiopulmonary bypass [CPB], but 6 of them [75%] were able to separate from CPB with IABP. They all were withdrawn from the balloon. Four [50%] of them are hospital survivors, and alive at the time of this report. 4 additional patients were assisted with IABP, postoperatively. 2 of them [50Yo] were withdrawn from the balloon but died. The overall survival and balloon weaning rates are 33.3% [4/12] % 66.7% [8/12], respectively. IABP was most effective when applied early to patients who had transient and reversible injury to the myocardium.

Synovial chondromatosis is an uncommon benign lesion characterized by metaplastic cartilage formation within the synovial connective tissue, usually intraarticular, commonly affects the knee, hip and elbow. An extraarticular lesion is rare, most often seen in a synovial sheath and bursa of the hand or foot. We present a case of extraarticular synovial chondromatosis in the left ankle, originated from the FHL tendon sheath of a 31 year-old-female diagnosed by a radiography, MRI confirmed histopathologically.

This study was to estimate the reduction effect of nonpoint source pollutants according to the rainfall intensity and drainage of infiltration grate inlet. Soil infiltration flow was measured on-site and SS load by the filter part was calculated by the experimental data in laboratory reactor test. Soil infiltration flow was measured to be about $1m^3/hr$ in soil condition saturated with water. The filter part of the infiltration grate inlet was a hydraulic equipment unhindered by soil infiltration on the bottom of the storage tank, because the infiltration flow was measured to be about $3m^3/hr$ continuously in the closing infiltration hole condition. Infiltration flow and SS load were over about $1m^3/hr$ and 1.71 kg according to laboratory results by the filter part using the artifical sample. Therefore, the above values could be presented as the limitted value to start the reduction of filtration effect. Reduction efficiencies of SS load by the filter part for the rainfall intensity were about 87 % at 5 mm/hr and about 61 % at 10 mm/hr in consideration of one infiltration grate inlet got the drainage area about $200m^2$. The reduction efficiency of nonpoint source pollutants was very effective in the first flush rainfall. However, the reduction efficiency by rainfall density was higher than by flow.
