During the last 33 months period between June, 1989 and March, 1992 Extracorporeal shock wave lithotripsy (ESWL) was performed 275 patients with lower ureteral stone by Northgate SD-3 Litho-triptor. Stone localization was done by ultrasonography and diazepam & fentanyl citrate was used intravenously to control pain during procedure in all patients. The success rate of treatment (rate free of calculi plus that of clinically insignificant residual fragment) was 98.1% below lO㎜ in stone size, 95.7% in ll-20㎜, 87.5% in 21-30㎜, 50% over 31㎜ and total mean success rate was 96.7%. Among the ESWL-failed 9 cases, ureterolithotomy was done in 5 cases, ureterorenoscopy in 2 cases and ston basket in 2 cases. Complications after ESWL were transient hematuria 100%, flank pain 7.3% and fever 1.8% and treated conservatively. Extracorporeal shock wave lithotripsy monotherapy with the Northgate SD-3 lithotriptor was considered to be effective and safe procedure for the initial treatment of lower ureteral stone.

"Biomaterials" are nonviable materials used in medical devices, intended to interact with biological systems. They should have "biocompativility", which is defined as the ability of materials to perform with an appropriate host response in a specific application. It includes many materials that are often classified as biomaterials. Metals, ceramics, polymers, glasses, carbons, and composite materials are some examples. Among them, biodegradable polymers are discussed in this revies article. Since a biodegradable polymeric implant does not have to be removed surgically once it is no longer needed, biodegradable polymers are of value in short-term applications that require only the temporary presence of a polymeric implant. Main short-term medical applications of biodegradable polymers include the temporary tissue scaffold, the temporary adhesion barrier, the drug delivery device, and the multifunctional implant. In this article, the properties, processing methods, and medical applications of the biodegradable polymers are reviewed.

Renal angiomyolipoma is an uncommon benign tumor of the kidney that consists of smooth muscle, blood vessels and mature adipose tissues. The most common benign renal tumor associated with spontaneous non-traumatic perirenal hemorrhage is angiomyolipoma, because of high vascularity. The ultrasonographic and computed tomographic images are sufficiently characteristic to permit accurate preoperative diagnosis. We report 2 cases of renal angiomyolipoma with spontaneous perirenal hemorrhage which were managed with nephrectomy.

We performed genetic analysis for detection of carrier state of Duchenne's muscular dystrophy (DMD). As genetic markers of the disorder, We used DNA-sequence polymorphisms detected with 6 different DNA probes derived from the vicinity of the DMD locus at genetic distance less than 15 cmo or from within the gene. on the short arm of X chromosome. In the family we studied. a consultand was a 29 years old woman whose maternal grandfather was a DMD patient who was unavailable. Therefore, all of her maternal aunts were DMD carriers whose next generations were requested for DNA studies. On the basis of linkage analysis. a proband and her niece were deemed to be unaffected with an accuracy of more than 99%, and we anticipated another two femals and one malt to be unaffected with 98% probability (normal serum creatine kinase level) where crossover events between intragenic(pERT 87.30) and flanking probes(pXUT23) were detected. but carrire risk of a female with the same haplotype was elevated to 41% taking account of an increased serum creatine kinase level. Two other females were predicted to be affected with 99.9 and 97.1% probabilities each. However. a genetic interpretation was impossible for one male in which a crossover breakpoint could not be determinied because of his mother's homozygosity of the alleles between crossovered alleles where hitherto pessibility of intragenic crossover could not be ruled out Our experience suggests that genetic diagnosis based on recombinant deoxyribonucleic acid techniques are assuming increasing importance. and provide a highly accurate method for carrier detection and prenatal diagnosis of DMD. By the way, despite the large number of intragenic and flanking DNA polymorhpisms available, uncertainties often remain in the genetic diagnosis of DMD. Pitfalls are presented by the large size of the region in which Duchenne's mutations can occur. Crossover events in this region. especially intragenic ones, which result in an exchange of DNA between two X chromosomes, can,rener DNA-marker studies inaccurate.

요로결석 환자의 체외충격파쇄석술 치료경과와 결석 특성과의 관련성

김성길,김기순,류소연,한미아,이선옥,노준 朝鮮大學校 附設 醫學硏究所 2009 The Medical Journal of Chosun University Vol.33 No.S

요로 결석에 대한 비 침습적 치료 방법인 체외충격파쇄석술에 의한 치료경과와 결석 특성과의 관련성을 파악키 위해 2002년 12월부터 2008년 3월까지 G시 H병원에서 요로 결석으로 진단되어 체외충격파쇄석술을 받은 33l례를 대상으로 의무기록 자료를 이용하여 분석한 결과는 다음과 같다. 1. 조사 대상자 331례중 남자는 68.6%, 여자는 31.4%이었으며 평균연령(표준편차)은 44.2 (13.9)세 이었고 84%가 G시내 거주자였다. 2. 조사 대상자에게 시행된 체외충격파쇄석술의 평균 시술횟수(표준편차)는 1.9(1.5)회 이었으며 평균 통증제거기간(표준편차)은 3.2(2.1)일 이었고 요로결석 진단 시로부터 치료가 완료되었다고 의사가 판정했을 때까지의 치료기간의 평균(표준편차)은 10.3(8.4)일 이었다. 3. 시술횟수에 통계적으로 유의하게(P<0.01) 관련된 요인은 결석크기, 결석의 방사선 투과성, 요관 폐색여부 이었으며 모형의 설명력은 13.5%이었다. 4. 통증제거기간에 통계적으로 유의하게(P<0.01) 관련된 요인은 결석의 방사선 투과성 이었으며 모형의 설명력은 7.4%이었다. 5. 치료기간에 통계적으로 유의하게(P<0.01) 관련된 요인은 결석크기와 결석의 방사선 투과성 이었으며 모형의 설명력은 13.5%이었다. 따라서 결석의 크기가 크거나 결석이 방사선에 비 투과성일 때, 요관이 폐색되어 있을 때 치료경과가 늦게 됨으로 이러한 사실을 참고 하여 추후 진료지침을 작성 시 보다 효과적이고 효율적인 치료법을 적용할 필요가 있다고 판단되며 보다 체계적인 평가와 연구가 필요할 것이다. Objectives & Methods: To find the treatment process by extracorporeal shock wave lithotripsy (ESWL) and its related stone characteristics in urinary tract stone patients, an analysis was done from medical records of 331 cases who were treated by ESWL from December 2002 to March 2008 at H hospital in G city. Results: Among 331 study subjects 68.6% were male and 31.4% were female. Their mean age (standard deviation, SD) was 44.2 (13.9) years old and 84.0% lived in G city. Average frequency of ESWL done toward study cases were 1.9±1.5 times. Mean duration of disappearance from pain was 3.2±2.1 days and total treatment period for a stone was 10.3±8.4 days. Statistically significant (p<0.01) stone and urinary tract characteristics related with frequency of ESWL were stone size, radio-opacity of the stone, and obstruction of urinary tract. The model composed of these 3 independent variables explained 13.5% of frequency of ESWL. Statistically significant (p<0.01) variable related with disappearance from pain was radio-opacity of the stone, and this model explained 7.4%. Statistically significant (p<0.01) variables related with treatment duration due to stone were stone size and radio-opacity of the stone. These two variables explained 13.5%. Conclusion: The bigger the size of stone are, the slower the treatment process will be. And when the stone is radio-opaque and urinary tract is obstructed, the treatment process will be slower than stone is radio-luscent and urinary tract is not obstructed. So to make effective and efficient treatment manual for ESWL, above fact must be considered and continuous systematic evaluation and research toward ESWL are necessary.

In a previous study, we developed a new food additive as an egg yolk antibody (IgY) against carbohydrate digestion enzymes for the regulation of blood glucose level and weight control. The IgY delayed and decreased the increment of blood glucose level after administration of sucrose in human being by 30% in 20∼30 min. We also developed a lipase inhibitor as a water extract of two kinds of herb, Platycodon grandiflorum and Solanum melongena. Twenty three volunteers were subjected to the intake of the egg yolk IgY plus the herbal extracts for 50 days. In average, the treated subjects appeared to lose 1.96 ㎏ of body weight and 3.4 ㎏ of body fat mass during the treated period. Furthermore, Panniculus adiposus and breech size were significantly decreased during the experimental period. Above results suggested that the administration of the dietary additives composed of egg yolk IgY and natural herbal extract improve the obesity by the decrement of body weight and body fat mass.
