Sclerotherapy has been demonstrated as an effective and minimally invasive procedure for varicose veins of the lower limbs, which can be performed on an out-patient basis. Between March 2000 and August 2001, we reviewed 138 patients who had been diagnosed as chronic venous disease in our hospital, and treated and evaluated a total of 32 limbs in 21 patients with primary varicose veins. There were 18 women and 3 men whose age was ranging from 31 to 55 years old, with a mean of 41.7 years. Eleven of 21 patients had bilateral involvement of lower extremity. Sclerodex(Sclerosant) was administered for telangiectasia less than 1mm and reticular vein less than 4mm, and Thromboject(Sodium Tetradecyl Sulfate) was for reticular vein more than 4mm. Two types of operations were stripping of saphenous vein (6 cases) and high ligation (18 cases). All patients were cosmetically satisfied with the results. Minor complications after injection such as 7 cases (21.9%) of erythema, 5 cases(15.6%)of bullae, 4 cases (12.5%)of thrombosis were occurred. However, no permanent change such as skin necrosis and pigmentation were appeared. Systemic responses such as dizziness or sweating were not observed in anyone. Sclerotherapy should improve both the safety and efficacy of the treatment of varicose vein. Our study suggests that the careful evaluation before planning the treatment of varicose vein is important for exact choice of patients and proper results.

김찬우,이수진,김지영,황규태,최윤영 대한핵의학회 2017 핵의학 분자영상 Vol.51 No.1

Purpose To identify differences between three-phase bone scan and SPECT/CT (TBS) and WBC SPECT/CT (WS) and compare diagnostic accuracies of each modality in patients with suspicious post-traumatic osteomyelitis (OM). Methods Twenty-one patients with suspicious post-traumatic OM were enrolled. All patients performed TBS and WS within 1 week. Foci ofMDP andWBC accumulation were divided into three categories: bone (OM), soft tissue (soft tissue inflammation; STI), negative for inflammation (NI). Confirmative diagnosis was made upon operative pathology or long-term clinical follow-up. Results Of 21 patients, four OM, eight STI, nine NI were finally diagnosed. TBS diagnosis was correct in three of four positive cases and nine of 17 negative cases. Sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV) of TBS were 75 %, 52.9 %, 57.1 %, 27.3 %, 90 %. WS diagnosis was correct in two of four positive cases and 17 of 17 negative cases. Sensitivity, specificity, accuracy, PPV, NPV were 50 %, 100 %, 81.0 %, 100 %, 89.5 %. Twelve of 21 cases showed agreement between TBS and WS. TBS misdiagnosed nine cases (six STI and two NI as eight OM; one OM as one STI), while WS misdiagnosed four cases (two OM as two STI; two STI as two NI). Combining results from TBS and WS led to better diagnostic accuracy (91.7 %) than either TBS or WS alone. Conclusion TBS and WS showed moderate agreement in assessment of clinically suspected post-traumatic OM. WS better evaluated inflammation than TBS. WS tended to underestimate inflammation whereas TBS tended to overestimate inflammation. Combining TBS and WS enhanced diagnostic accuracy.

감자 분무경산 소괴경을 심지양액 재배하여 기본식물을 생산할 때, 심지의 배치방법에 따른 씨감자의 생산성 조사하고, 심지를 수평으로 배치할 때 알맞은 심지수를 구명하고자 상자(51x31x20cm , 0.16m2 )당 심지 6개를 수직으로 배치하는 처리와 2~10 개의 심지를 수평으로 배치하는 처리를 두었다. 괴경수는 심지 6개를 수직으로 배치하는 것에 비하여 수평으로 배치함으로 증가하였고 평균괴경중은 감소되어, 괴경수량은 심지 6개의 배치방법에 의하여 영향을 받지 않았다. 상위급씨감자로 사용될 수 있는 5 g 이상의 괴경수는 심지수가 2개에서 6개로 증가됨에 따라 2.8개/주에서 8.0개/주로 증가되었으나, 심지수 6 이상에서는 더 증가되지 않았다. 평균괴경중은 심지수 8개까지 심지수가 많을수록 무거웠으나 심지수 10개에서는 더 이상 무거워지지 않았다. 5 g 이상의 괴경수량은 심지수가 2개에서 6개로 증가됨에 따라 1.81 kg/m2 에서 9.72 kg/m2 으로 크게 증가되었다가, 8개 이상에서는 심지수 증가에 따라 완만히 증가되어 심지 10개 처리구에서는 12.9 kg/m2 이었다. 씨감자 수량과 심지비용, 배지충진 작업의 편리성을 고려할 때 상자당 심지 8개(50.6개/m2 )를 상자의 밑면에 눕혀 수평으로 배치하는 것이 유리할 것으로 판단된다. A glasshous experiment was carried out in 2002 to evaluate growth differences between two wick types, and to determine the optimum number of wicks in a wick-based hydroponics for production of 'Dejima' seed potatoes (Solanum tuberosum L.). The six minitubers (7.0~pm0.2g /tuber) produced through aeroponics were planted in a polystyrene box (51 cm long ~times 31 cm wide ~times 20 cm high) containing growth medium (perlite+peatmoss 1:2, v/v mixtures). Before the boxes were filled with the medium, 6 wicks per box were vertically and 2 to 10 wicks were horizontally installed, respectively, at the bottom of the boxes through holes. Comparing with 6 vertical wick treatment, 6 horizontal wick treatment increased the number of tubers per plant, but decreased average tuber weight. Yield of tubers greater than 5 g (seed potatoes) was not significantly affected by wick type. As the number of the horizontal wicks per box was increased from 2 to 6, the number of seed potatoes increased from 2.8 to 8.0/plant and then leveled off. Average tuber weight increased with increasing the number of the wicks up to 8 and then leveled off. As the number of the wicks per box was increased from 2 to 6, seed potato yield increased from 1.81 to 6.59 kg/m2 and then slowly increased up to 10 wicks per box, reaching 12.9 kg/m2 . The results indicate that installing 8 wicks per box (0.16m2 ) horizontally for the wick culture system in production of 'Dejima' seed potatoes is beneficial considering seed potato yield, cost of wicks, and convenient filling with medium.

Purpose: Tie-over dressing is widely used to secure skin grafting on face, body, or extremities. It can be a rather complicated task and is not easy to make compressive dressing again if performed in a conventional method. So, we hereby introduce an easy reproducible tie over dressing method. Methods: After completing the skin graft, Cut the silastic drainage longitudinally in half and spread to the grafted skin margin. Drainage is fixed by using the stapes or sutures. A fluffy gauze bolus dressing is placed over a furacin impregnated gauze and wrapped around. After suturing the distal margin of silastics with opposite side using the silk thread either 5 - 0 or 3 - 0, knot of suturing, which is pressed down against the dressing while the threads are tightened, is made into center of each sides. Results: It can make dressing again after observing the grafted skin, and it can also make pressure on the grafted area evenly until the grafted skin is taken. Conclusion: This dressing method makes the surgeons and patients comfortable. To surgeons, it provides more rapid and easier way to do dressing, and to patients, it eliminates pain caused by redressing.

간동맥화학색전술시 Fast Low Dose C-arm CT와 DSA의 선량 비교 및 Fluoroscopy 선량에 대한 고찰

김찬우,최지웅,정현묵,강래욱,주건환,김창식,방기성,이임범 대한인터벤션영상기술학회 2018 대한인터벤션영상기술학회지 Vol.21 No.1

목적 : 본 연구는 간동맥화학색전술에서 자주 활용되고 있는 Fast Low Dose C-arm CT의 평균선량을 DSA의 평균선량과 비교해 보고, 전체 누적선량에서 많은 비중을 차지하는 검사기법을 분석하여 환자와 시술자의 피폭선량을 낮추고 시술의 효율성을 높이는데 도움을 주는 방안을 찾아보고자 하였다. 대상 및 방법 : 1) 본원에서 사용 중인 Philips Allura Xper FD20 장비로 2017년 12월부터 2018년 02월까지 간동맥화학색전술을 받은 환자 50명을 임의로 선정하여 Fast Low Dose C-arm CT와 DSA의 DAP(mGyㆍ㎠) 및 Air Kerma(mGy)를 조사하여 비교하였다. 2) 동일한 환자 군을 대상으로 시술 당 전체 누적선량에서 4가지 검사기법들(DSA, Fast Low Dose C-arm CT, Roadmap, Fluoroscopy)의 누적선량(DAP, Air Kerma)이 차지하는 비중을 각각 분석하였다. 통계적인 비교 분석을 위해 통계프로그램 SPSS 20.0을 이용하여 각각 대응표본 T검정, ANOVA 검증(post hoc test : Tukey)하였고, p value가 0.05 미만인 경우 통계적 유의성이 있는 것으로 평가하였다. 결과 : 1) Fast Low Dose C-arm CT가 DSA에 비해 평균선량(DAP, Air Kerma)이 통계적으로 유의하게 낮다고 말할 수 있다.(p<.0001) 2) 검사기법에 따라 차지하는 누적선량(DAP, Air Kerma)의 비중은 유의한 차이를 보였으며(p<.0001), 전체 누적선량에서 DSA와 Fluoroscopy를 합한 누적선량의 비중은 유의한 수준에서 높은 것으로 나타났다. (DAP : 87.18%, Air Kerma : 90.04%) 결론 : 간동맥화학색전술에서 항암제 주입 전후로 Fast Low Dose C-arm CT를 적극 활용하여 DSA의 검사 횟수를 가능한 줄인다면 환자들의 의료피폭을 줄이는데 도움이 될 것으로 생각된다. 또한 의도적으로 Fluoroscopy time을 줄이려는 노력과 함께, 가능한 Fluoroscopy Frame율을 진단이나 시술에 영향을 주지 않는 범위 내에서 최소로 낮추어 시술한다면 피폭선량 감소에 상당한 도움이 될 것으로 사료된다.

심지양액재배 ‘대지’의 씨감자 크기에 따른 포장 생육과 수량

김찬우,송창길,강봉균,전용철,강영길 한국작물학회 2010 한국작물학회지 Vol.55 No.1

심지양액재배 씨감자의 크기가 노지포장에서의 생산성 반응을 검토하기 위하여 봄재배에는 <1, 1~3, 3~5, 5~7, 7~10, 10~20, 20~30, 30~50, 50~80 g의 심지재배 씨감자를 심었고, 가을재배에는 봄재배의 0.2~1과 50~80 g의 처리를 제외하고 7, 15 g의 분무경에서 생산된 씨감자를 처리로 추가하여 생육및 수량을 조사하였다. 출현율은 두 재배시기 모두 씨감자의 크기가 10~20 g까지에는 씨감자가 클수록 크게 증가하였으나, 10~20 g 이상의 씨감자 파종구에서는 88% 이상으로 더 이상 유의성 있게 증가되지 않았다. 출현일수는 봄재배의 경우 34일 내외로 씨감자의 크기에 따른 유의한 차이가 없었으나, 가을재배에서는 씨감자의 크기가 1~3 g에서 30~50 g으로 커짐에 따라 34일에서 16일로 크게 단축되었다. 씨감자 크기가 커짐에 따라줄기수가 많았으며, 줄기의 길이와 굵기 및 잎의 크기도 증가되는 경향이었다. 두 재배시기 모두 주당괴경수, 괴경평균중, 총괴경 및 규격씨감자 수량은 씨감자가 10~20 g까지 커짐에 따라 거의 직선적으로 많아졌고, 더 이상 씨감자가 커질 때 완만히 증가되는 경향이었다. 가을재배에만 심은 비슷한 크기의 심지양액재배와 분무경씨감자 사이에 총괴경 및 씨감자수량은 유의한 차이가 없었다. Two field experiments were carried out in 2002 to evaluate effects of the sizes of tubers produced through a wick-based hydroponics on growth and yield of seed potatoes (Solanum tuberosum L. 'Dejima'). Nine sizes of seed tubers (<1, 1~3, 3~5, 5~7, 7~10, 10~20, 20~30, 30~50, and 50~80 g) were used in spring crop. In fall crop, however, tubers except for the 1 g and 50~80 g wereused with tubers 7 and 15 g produced through aeroponics. Emergence rate greatly increased as tuber size was increased up to 10~20 g and then leveled off in both croppings. The number of days from planting to emergence in spring crop was about 34 days regardless of tuber size, while that in fall crop decreased from 34 to 16 days as tuber size increased from 1~3 to 30~50 g. The number of stems per plant, stem length and diameter, and leaf size tended to increase with tuber size. As the seed tuber size increased up to 10~20 g, the number of tubers per plant, average tuber weight, total and seed tuber yields linearly increased and then slowly increased with seed tuber size. Total and seed potato yields were not significantly different between tubers produced through a wick-based hydroponics and an aeroponics when similar sized tubers were planted in the fall cropping.
