Intra-arterial Chemotherapy (IAC) was performed to the 34 patients with nonmetastatic osteosarcoma using Cisplatin and surgery was done in 26 cases out of 34. We analysed the therapeutic effect of IAC in the view of local control rate and distant metastasis for two and half years. local control rate was 94% on the base of the radiologic studies including simple X-ray, angiography and CT. No viable cells were observed in 50% of the cases on the pathologic examination of the surgical specimens. Distant metastasis developed in 14 cases 9415) , mainly in the lung, No significant complications occurred except each case of acute renal failure, congestive heart failure and peripheral embolism, which were improved by proper management. IAC is one of the most effective methods in controlling the regionally confined osteosarcoma, but it may be incorperated with other adjuvant protocols to decrease the chance of delayed metastasis.

Radiologic findings of Total Colonic Aganglionosis (T.C.A.) were analized in 15 patients with the results as follows; 1. Male to female ratio was 8:7. 2. There were six cases of small calibered colon, seven cases of normal colon and two cases of megacolon. 3. Free reflux of barium into the small bowel was observed in seven cases out of eight in which retrograde filling was tried. 4. Delayed films (24hrs or more) were available in eight cases and most of the barium remained in bowel in six cases. 5. There were abnormal colonic cotractions in three cases, decreased redundancy in five and five cases of irregular, hypertrophic mucosal wall suggesting enterocolitis. 6. Part of ileum were also aganglionic in five cases. There seems to be no pathognomonic barium enema findings in T.C.A.. But combination of these findings may suggest the possibility of T.C.A. T.C.A. should be considered in differential diagnosis of bowel obstruction in infants. Barium enema should be complete and dela ed films always be obtained.

Cysticercosis, like other parasitic disease, is still endemic in many parts of the world, and is not infrequently found in Korea. The authors reviewed CT findings of 54 cases of the cysticercosis involving the central nervous system which were proven by pathology and clinical findings. The results are as follows: 1. Male to female retio is 3 : 1 and the most prevalent age group is the fifth decade. The most common sympton is seizure(56%). 2. Involved areas in the brain are parenchymal(66%), intraventricular(15%), leptomeningeal(40%) and the mixed(15%). 3. Pre-contrast CT findings are the round low density in 46 cases(85%), multiple pin-point calcification in 18 cases(33%), variable degrees of hydrocephalus in 20 cases(37%) and peripheral edematous change in 8 cases(15). 4. Post-enhancement CT findings are complete or partial wall enhancement in 28 cases(50%), nodular enhancement in 18 cases(32%) and pin-point enhancement in 10 cases(18%) which represents the enhancement of the scolex per se. Basal cisternal enhancement is seen in one case, which is very unusual finding of cysticercosis cellulosae.

It has been reported that newly developed nonionic contrast material is less effective in anticoagulation than ionic contrast media. Anticoagulation properties were studied with high osmolar ionic contrast medium(diatrizoate) low osmolar ionic medium(ioxaglate) and low osmolar nonionic contrast medium(iopromide) as well as with normal saline for control Arterial blood was taken from 10 adults before angiography. Two ml. of the arterial blood was introduced into the plastic syringes containing 2 cc. of each contrast medium and saline. The syringes were kept undisturbed in room temperature for 10 minutes 30 minutes 60 minutes 90 minutes and then the blood-contrast mixture was poured on the filter paper to detect the clots formed in the syringes. Delay of the clotting time was also checked in the contrast media with various concentraions of 100% 30% 10% and 3% Chi-square test of the data shows very significant difference in antico-agulation effect between the ionic group(diatrizoate ioxag-late) and the nonionic one (iopromide) Clotting time in the nonionic medium(iopromide) was shorter in 30% concentration than that of the ionic material(diatrizoate ioxaglate) Nonionic contrast medium(iopromide) has anticoagulation effect but less effective than ionic media(diat-rizoate ioxaglate).

벽식 스틸하우스 벽체의 구조재로 적용되어 오고 있는 박판냉간성형형강 스터드의 경우 열교현상에 의한 단열상의 문제를 가지고 있기 때문에 추가적인 단열재의 사용이 요구된다. 이러한 단열 문제를 해결하기 위하여 웨브에 슬릿이 배치된 냉간성형강 단열스터드가 개발되었다. 그러나 슬릿의 배치로 인하여 단면강도 산정은 대단히 어려운 문제점이 되고 있다. 본 논문에는 단열스터드의 압축강도 및 구조적인 거동에 대한 실험 및 해석적인 연구결과를 기술하였다. 슬릿의 길이, 간격 및 배열형태를 달리하는 세 종류의 단열스터드에 대한 압축실험을 단면의 파괴 시까지 수행하였으며, 실험 및 해석결과에 근거하여 복부에 슬릿이 있는 냉간성형강 스터드에 적용하기 위한 단순한 형태의 강도 산정방법을 제안하였다. 제안된 강도산정법에서는 단열스터드를 등가두께의 슬릿이 없는 일반스터드로 대치하고, 이 등가단면에 직접강도법을 적용하여 단열스터드의 공칭압축강도를 산출한다. 제안된 강도산정방법은 단열스터드 실험결과와 비교하여 검증하였다. The cold-formed steel stud, which has been used as a load-bearing member of wall panels for steel houses, poses a significant problem in insulation due to heat bridging of the web. Therefore, some additional thermal insulating materials are required. In order to solve this problem, the cold-formed steel thermal stud with slits in the web was developed. However, estimating the structural strength of thermal studs is very difficult because of the arrangement of perforations. In this paper, an analytical and experimental research on thermal studs is described. Three types of studs with different length, pitch and arrangement of slits were tested to failure. A simple design approach was proposed based on the test results. The proposed method adopted the direct strength method, based on the elastic local and distortional buckling stress of plain studs with equivalent thickness in the web instead of thermal studs. The predictions using the proposed method were compared with test results for verification and the adequacy of the proposed method was confirmed.

N/A Percutaneous transhepatic biliary drainage has played a major role in treatment of patients with biliary tract disease, especially obstruction by malignant disease. Percutaneous transhepatic biliary drainage was performed in 77 patients of obstructive jaundice for recent 2 years since June 1981 at department of radiology, Seoul National University Hospital. The results were as follows, 1) The male to female ratio was 2.3: 1 and the age ranged from 19 to 88 with average of 53. 2) The causes of obstructive jaundice included 69 malignant diseases and 8 benign diseases. Malignant diseases were 24 cases of bile duct cancer, 15 cases of metastasis, 11 cases of pancreatic cancer, 2 cases of gallbladder cancer and 1 case of ampulla Vater cancer. Benign diseases were 5 cases of common bile duct stone and 3 cases of benign stricture. 3) The most common indication was palliative drainage of obstruction secondary to malignant tumor in 54 cases. 4) The overall success rate was 94.8% Internal drainage was achieved in 24(31.2%) and external drainage was accomplished in 49(63.6%). 5) Decline in serum bilirubin level was made in 67 cases(91. 8%) with the most rapid decline within 1 week after the procedure. 6) Acute major complication occurred in 4 of 77 cases (5.2%). Percutaneous transhepatic biliary drainage is a proven technique for non-operative biliary decompression and established alternative to surgery.

문동규(Dong Kyu Moon),이헌영(Heon Yong Lee),김석진(Suck Chin Kim),임덕(Duck Lim),선덕재(Duk Jae Shun),박성회(Sung Hoe Park) 대한소화기학회 1982 대한소화기학회지 Vol.14 No.2
N/A The neodymium YAG laser was used to bleeding experimental house rabbit gastric ulcer in two separate studies: (1) Extensive investigation by using the l. 06 um YAG laser wave lenth, 2 mm in spot size, 30-90 watt power and 0. 5-l. 5 sec pulse duration were performed to determine opitimal YAG laser photocoagulation parameters to maximize hemostatic efficacy while minimizing associated tissue injury. 11 out of 21 combination of power, pulse duration and spot size, with coaxial CO2 were found to be useful. (2) 11 of these treatment combination were studied more detail to assess the respective effect of pulse duration and power. Four repeated study were performed for each combination. From these studies we conclude: (1) YAG laser photocoagulation effectively stopped experimental gastric ulcer bleeding when applied at laparotomy. (2) Under the upper described condition of pulse, spot size and pulse duration most useful combinations for hemostasis were following: a) In 0. 5 sec pulse duration; 60 watt and 70 watt power. B) In 1. 0 sec pulse duration; 50-90 watt power. C) In l. 5 sec pulse duration; 40-50 watt power. (3) 3 out of 44 combination were perforated (7%) (4) Mean effective joules for hemostasis were 220. (5) There were no close relation between decrease of tissue injury, joules, power and treatment time.
