주상신 대한영상의학회 1995 대한영상의학회지 Vol.32 No.1
Purpose : We evaluated both the patients and the normal volunteers to determine the diagnostic criteria ofsubacromial impingement syndrome. Materials and Methods : We analyzed the radiologic finding of Thirty degree ofcaudal tilt view (TCTV) and Supraspinatus outlet view (SOV) of 100 shoulders from 85 patients with clinicallyproved subacromial ipingement syndrome and normal 100 shoulders from 60 volunteers. Result : In TCTV, theprotrusion of acromion below the line of extension from inferior surface of clavicle was shown in 94% of thepatient group and 48% in normal group. Sharp tip of acromial protrusion was detectable in 55.3% of the patientgroup and 10.4% in normal group. In SOV, curved type of acromion was seen in 53% of the normal and 50% in patientgroup. Hooked type of acromion was deteted in 3% and 31% of the normal and patient group, respectively. Conclusion: Protrusion of acromion at TCTV itself was not a criteria of subacromial impingement syndrome, but more than 7mmbelow the line of extension from inferior surface of clavicle was meanigful. In SOV, hooked type of acromion was acriteria of subacromial impingement syndrome but curved type is was not a finding of diagnostic significence.Acromial spur formation on TCTV and SOV was important criteria of subacromial impingement syndrome.

Segmental Prevalence and Extraction Rate of Retained Intrahepatic Stone
Kwak, Byung Kook,Lee, Jong Beum,Joo, Sang Shin,Lee, Hwa Yeon,Shim, Hyung Jin,Kim, Kun Sang,Lee, Yong Chul 중앙대학교 의과대학 의과학연구소 1996 中央醫大誌 Vol.21 No.2
간내 잔류담석의 간 구역별 빈도와 제거율과 실패원일을 알고자 한다. 담석증으로 수술을 받고 T자관을 통하여 잔류담석 제거술을 시행 받은 환자중 간내담도에 잔류담석이 있던 126명을 후향적으로 담도조영사진을 분석하였다. 간내담도별 잔류 단석의 빈도와 제거율은 좌외측(left lateral)이 각각 54.0%, 91.1% ; 우후(right posterior)가 38.1%, 81.2% ; 우전(right anterion)이 26.2%, 93.8% ; 좌 내측(left medial)이 14.3%, 77.7%를 보였다. 전체 제거율은 85.6%이었다. 미상엽은 모든 예에서 간내 담석이 없었다. 제거 실패의 주된 원인은 담도 협착과 매복된 담석이었다. 우후와 좌내측 간내담도에서는 고유한 담도의 굴곡이 또 하나의 실패의 주된 원인이었다. 결론적으로 좌외측 간내담도가 담석의 빈도가 가장 높고 우후, 우전, 좌내측 간내담도의 순서로 높았다. 우후와 좌내측 간내담도의 담석제거율이 우전, 좌외측 보다 낮았으며, 이것은 고유한 굴곡 대문으로 설명된다. To evaluate the hepatic segmental prevalence and the extraction rate of the retained intrahepatic stones on cholangiogram and the cause of failure of percutaneous stone removal through a T-tube tract. One hundred and twenty-six patients who had undergone the extraction of the retained intrahepatic stones were evaluated. Selective segmental cholangiogrmas were obtained for each segmental prevalence by using a pre-shaped 10F catheter. The results of the segmental extraction rate and the cause of failure were also evaluated after completing the stone removal session. The segmental prevalence and the extraction rate were 54.0% and 91.1% in the left lateral(LL), 38.1% and 81.2% in the right posterior(RP), 26.2% and 93.8% in the right anterior(RA), 14.3% and 77.7% in the left medial(LM) segmental duct, respectively. The total extraction rate was 85.6%. The caudate lobe had no stone in all cases. The main causes of extraction failure were stricture and stone impaction. In the RP and the LM segmental duct, duct angulation was another amin cause of failure. The prevalence of retained stones is highest in the LL segmental duct, the RP, the RA and the LM segmental duct, in descending order. There was no stone in the caudate lobe. The extraction in the RP and LM segmental ducts is more difficult than in the RA and LL segmental ducts. This result can be explained by the natural anatomical angulation of these ducts.

에타놀, 고온 생리 식염수 및 고농도 식염수를 백서 간에 주입 후 조직학적 변화

Purpose : The purpose of this study was to evaluate the degree of liver injury after injection of ethanol, hot normal saline and hot hypertonic saline into normal rat liver. Materials and Methods : Sixty white rats weighing 200-300g were used. There were three groups (ethanol, hot normal saline, and hot hypertonic saline), and these were divided into subgroups (5 rats in each) according to amount of injected material and duration. Under ether anesthesia, each drug (ethanol -0.05ml, 0.1ml, 0.2ml ; hot normal saline -0.1ml, 0.2ml, 0.4ml ; hot hypertonic saline -0.1ml, 0.2ml, 0.4ml) was introduced directly into the liver. Pathologic specimens were obtained 7 and 14 days after injection. Results : With regard to histologic change after 7 days, the ethanol group showed less tissue damage such as coagulation necrosis and inflammatory infiltration-than the hot saline group. There was however, no significant difference among the three groups in tissue damage at 14 days. Nor was there any significant histologic difference between the different saline concentration groups. Conclusion : Histologically, there was no significant difference among the three groups in tissue damage at 14 days, and it is suggested that this is due to irreversible change in damaged tissue. Tissue damage was caused mainly by the high temperature of saline rather than by high osmolarity.

Purpose : The in vitro dissolution of intrahepatic stones was evaluated using the various solvent mixtures.Materials and Methods : Sixty four intrahepatic stones from 16 patients were used. Four kinds of solvent mixtures(No.1 = basic buffer + EDTA, No.2 = 1 + Sulfobetain-12, No.3 = 3 + N-acetylcysteine, No.4 = 3 + urea) were used.Dissolution rates were determined by measuring the weight loss of stones after 6, 12, 24, 48 hours incubationperiods, respectively. Results : The highest dissolution rates in dissolving intrahepatic stones were achievedwith No.4 solvent mixture(1% W/V EDTA/80mM, Sulfobetain-12/1M, urea, pH 9.5). Conclusion : Intrahepatic stonescould be largely dissolved up to about 70% of their initial weight after 48 hours incubation period in vitro.
