Excretory urography is a type of contrast study used to verify and localize upper urinary tract disease. It is an inexpensive and easy way to visualize of anatomic and functional status of the kidney and has been used as a primary imaging modality for the evaluation of urinary tract abnormalities. We describe urological signs of 7 dogs who examined with excretory urography and ultrasonography. Six cases were referred to veterinary medical teaching hospital. Chungnam national university (VMTH, CNU) to evaluate renal function after the treatment for renal failure and one case was referred showing hematuria. In case 1, 2 and 4, blood test and urinalysis was normal and the results of excretory urography presented that renal function were normal range. In case 3, the results of urinalysis, ultrasonography, and excretory urography except blood test presented abnormal kidney and hydronephrosis was diagnosed. In case 5 and 6, blood test, urinalysis, ultrasonography and excretory urography indicated renal failure. In case 7, blood test, urinalysis and ultrasonography presented partially abnormal signs, however, the results of excretory urography was normal range.

본 실험에서는 다래나무 및 노각나무 수액을 천연 건강음료로 개발하기 위한 기초 자료를 얻고져 물리ㆍ화학적 성질과 유리당, 무기물 및 구성 아미노산 등을 분석하였다. 다래나무와 노각나무 수액의 pH, 비중, 당도, 수분, 회분 및 조단백질의 함량은 거의 비슷하였다. 유리당 함량은 fructose가 다래나무 수액에서 378.4㎎/100㎖, glucose는 노각나무 수액에서 125.4㎎/100㎖로 가장 높은 함량이었다. 무기물 조성은 망간과 알루미늄을 제외한 모든 무기물에서 노각나무 수액에 비해 다래나무 수액에서 함량이 높았으며 특히 칼슘은 다래나무 수액이 172.0㎎/ℓ, 노각나무 수액에서 13.7㎎/ℓ로 다래나무 수액이 노각나무 수액보다 약 13배나 높은 함량을 보였다. 다래나무 및 노각나무 수액은 분석된 총 17종의 구성 아미노산 중 다래나무 수액은 4종, 노각나무 수액에서는 6종이 검출되었는데, 다래나무 수액은 cystine, aspartic acid, serine 그리고 valine의 순으로 노각나무 수액에서는 cystine, glutamic acid, aspartic acid, serine, valine 및 phenylalanine 등의 순으로 함량이 높게 나타났다. Natural compounds such as free sugars, minerals and composition amino acids in Darae(Actinidia arguta) and Korean stewartia(Stewartia koreana) saps were analyzed to establish to the basic data of foods. Free sugars of the saps determined were fructose and glucose which were detected higher amounts as 378.4 and 125.4㎎/100㎖, respectively, but sucrose and maltose were not detected. Among 10 kinds of mineral detected in the saps, the content of calcium in Darae and aluminum in the Korean stewartia saps was the highest 172.0 and 56.1㎎/ℓ, respectively. The calcium content in Darae saps was 13 times higher than that of Korean stewartia saps. The Darae saps were composed of 4 kinds of amino acids such as cystine, aspartic acid, serine and valine, and then Korean stewartia saps 6 kinds of amino acids such as cystine, glutamic acid, aspartic acid, serine, valine and phenylalanine. It is concluded that saps of Darae and Korean stewartia contain a good variety of natural compounds such as free sugars, minerals and amino acids to serve as an excellent source of very natural and health promoting drinks.

Purpose: The purpose of this study is to determine the level of pain related to a blood sugar test. Specifically, the study attempts to compare the varying degree of pains when different types of blood sugar test are used. Method: A sample of 56 subjects is composed of DM patients admitted to a medical ward of C university hospital in Gwangju. Data were collected from July, 2001 to December, 2001. The blood sugar tests were administered in four different ways: (1) the use of 27G needle only. (2) the use of 27G needle followed by ice-packed treatment, (3) the use of 27G needle after EMLA cream application, and (4) the use of lancet. The degree of pain is measured with a visual analogue scale and performed twice. Result: in both measures, the use of 27G needle only method is shown to cause the highest level of pain in comparison with the rest of methods (F=4.01, p=.01; F=8.14, p=.00). However, the differences in pain between time in all methods were not found to be significant (t=-.85, p=.40; t=.80, p=.42; t=.31, p=.75; t=.19, p=.85). Conclusion: The study results indicate that the method using lanceter is more recommendable than the use of 27G needle only method. Further research is needed to support the current study result with the use of different measurement scales and to determine effective methods of blood sugar test to lower pain and compliance.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

Benson's Group Additivity Method를 이용한 염화다환방향족 화합물의 열역학적물성치 평가와 생성반응경로에 관한 연구

도시폐기물 소각시설에서 다이옥신류는 chlorobenzene, chlorophenols, PCBs등의 염소성분이 포함된 방향족화합물과 함께 폐기물의 소각처리시 불완전 연소로 인해 주로 생성된다. 이들 다이옥신 생성에 대한 반응메카니즘의 예측에 필요한 다이옥신을 형성하는 전구물질인 분자 및 radical의 정확한 열역학적 물성치를 평가하기 위해 Benson's group additivity method에서는 고려되지 않는 Cl, F, OH, CH3등과 같은 2개 이상의 치환기가 결합된 방향족화합물에 대한 computer code인 THERM을 이용하여 엔탈피(Hf), 엔트로피(St), 열용량(Cp)을 평가하였다. 또한 이와 같은 열역학적 물성치 평가법의 신뢰성을 검토하기 위해 다양한 방향족화합물에 대한 실험적으로 측정된 문헌치와 평가치와의 절대오차는 para-cresol의 0.02kcal/mole에서 hexamethylbenzene의 3.46kcal/mole로 좁은 범위를 나타내었다. 또한 다이옥신을 생성하는 전구물질들의 열역학적 물성치를 THERM을 이용해 간접적으로 평가함으로써 다이옥신을 형성하는 주요 생성반응 경로에 대해 살펴본 결과는 다이옥신을 형성하는 기초반응(elementary reaction)중 욤소수가 많은 반응물질일수록 반응이 더 잘 일어남을 알수 있었다. Chlorinated dioxins are often observed in effluent from oxidation or incineration such as chlorobenzenes, chlorophenols and PCBs. It would be of significant value to have an accurate and fundamental understanding of the mechanism for dioxin formation, in addition to the knowledge of dioxin thermodynamic properties, in order to assist in the design of stategies to effectively control or reduce emissions of these compounds. Very little has been published on the thermodynamic properties and elementary reactions which lead to formation of dioxins. Benson group additivity method, when used for the estimation of thermodynamic properties of molecules, does not account for all interactions between functional groups or atoms on aromatics, such as chlorines, hydroxyl or ether linkages. Therefore thermodynamic properties of dioxins are estimated by THERM based on Benson's group additivity method corrected by interactions group. Absolute errors between our predictions and literature values range from a low of 0.02 kcal/mole for paracresol to a high 3.46kcal/mole for hexamethylbenzene. We use these thermodynamic calculations to show the feasibility of several elementary reaction pathways leading to dioxin formation, where the presence of chlorine acts to enhance or lower the Gibbs free energy of reactions.
