Purpose: To evaluate the clinical manifestations and the results of treatment in congenital lacrimal fistula. Methods: We retrospectively evaluated the symptoms, associated anomalies, and results of treatment in patients with congenital lacrimal fistula. Results: The mean age of the 22 total patients was 22.5±24.6 years (4 months~77 years). Associated anomalies were shown in two patients - one with hearing loss and upper punctal atresia, and the other with imperforate anus and undescended testes. Symptoms were tearing in 18 eyes and subcutaneous nodule in 3 eyes. Most of the external ostium of the fistula were located at the skin inferomedial (16 eyes) or medial (5 eyes) to the medial canthus, but one case had external ostium at the medial palpebral conjunctiva. Symptom improved in all patients after fistulectomy with bicanalicular intubation in 12 eyes, fistulectomy in 1 eye, bicanalicular intubation in 1 eye, and dacryocystorhinostomy combined fistulectomy with bicanalicular intubation in 2 eyes. However, the fistula recurred in 3 cases (19%). Conclusions: Lacrimal fistula is a congenital anomaly which can cause tearing or subcutaneous nodule. Treatment appropriate to the patient is required to get favorable result.

Purpose: To evaluate the accuracy and the influencing factors of partial coherence interferometry in intraocular lens (IOL) power calculation for cataract surgery. Methods: In 86 eyes of 69 patients who had undergone cataract surgery, we measured axial length using both IOLMaster and contact type ultrasonography, calculated the target refraction with SRK II formula and compared the result with the measured value after operation. We also evaluated the factors influencing the accuracy of the power calculation such as age, sex, type of cataract, severity of nucleosclerosis, corneal power, and preoperative refraction. Results: In IOLMaster and contact type ultrasonography, the mean axial lengths were 23.70±1.27 mm and 23.55±1.28 mm (p<0.01), and the mean absolute errors (MAE) of refraction were 0.53±0.26D and 0.66±0.39D (p<0.01) respectively. The eyes of longer axial length showed larger MAE than those of shorter axial length (p=0.02). Conclusions: Partial coherence interferometry was more accurate than contact type ultrasonography in IOL power calculation. The factor associated with the accuracy of partial coherence interferometry was the axial length.

Objectives : This study was examined to investigate the effects of Cheonmagudeng-um gagam (CGG) extract on spontaneous hypertension. Methods : For the study of CGG, we divided rats into three groups. The normal group was Wister Kyoto rats (WKY). The control group was spontaneously hypertensive rats (SHR). The treatment group was SHR which were administered CGG extract (SHR-CGG). SHR-CGG were orally administered CGG extract that was diluted in distilled water at the various concentrations for 4 weeks (234.5 mg/kg) and SHR were orally administered the same dosage of plain distilled water as SHR-CGG. Then we measured anti-oxygen effects, ACE inhibitory activity, weight of heart and kidney, blood pressure, heart rate, plasma aldosterone, electrolyte, creatinine, uric acid, BUN, and observed the cortex of the cardiac muscle, kidney, and adrenal gland. Results : CGG increased DPPH scavenging activity and SOD similar activity depending on the concentration. CGG significantly decreased ROS, TNF-${\alpha}$, IL-6, IL-$1{\beta}$, heart weight, blood pressure, heart rate, aldosterone, and BUN in SHR. CGG increased ACE inhibition activity depending on the concentration. CGG inhibited the heart, kidney and adrenal gland tissue injury that is caused by hypertension. Conclusions : These results suggest that CGG is effective in treatment and prevention of hypertension.

평창강 수계의 어류상을 알아보기 위하여 1992년 10월부터 1994년 6월까지 총 6회에 걸쳐 15개 지점을 선정하여 조사하였다.<BR> 본 연구결과 어류는 총 8과 27속 37종이 확인되었으며 금강모치(Phoxinus kumgangensis), 갈겨니(Zacco temmincki), 쉬리(Coreoleuciscus splendidus), 묵납자루(Acheilognathus signifer), 배가사리(Microphysogobio longidorsalis), 참마자(Hemibarbus longirostris) 등이 우점하였다. 홍정천 수계에서 열목어(Brachymystax lenok)가 확인되었으며 홍정천, 홍정천과 속사천의 합류지점, 그리고 평창강 중류에서 천연기념물 259호인 어름치(Hemibarbus mylodon)가 확인되었다. 그외 금강모치(Phoxinus kumgangensis), 어름치(Hemibarbus mylodon), 쉬리(Coreoleuciscus splendidus), 가는돌고기(Pseudopungtungia tenuicorpus), 몰개(Squalidus japonicus coreanus), 참중고기(Sarcocheilichthys variegatus wakiyae), 줄납자루(Acheilognathus yamatsutae), 묵납자루(Acheilognathus signifer), 돌상어(Gobiobotia brevibarba), 꾸구리(Gobiobotia macrocephalus), 돌마자(Microphysogobio yaluensis), 배가사리(Microphysogobio longidorsalis), 참종개(Cobitis koreensis), 새코미꾸리(Cobitis rotundicaudata), 퉁가리(Liobagrus andersoni), 미유기(Silurus microdorsalis), 꺽지(Coreoperca herzi) 등 다수의 한국특산종들이 서식하고 있어 평창강은 남한강 수계 중 강원도 영서지방의 대표적인 어류상을 갖는 것으로 확인되었으며 따라서 이들 어종에 대한 보호에 힘써야 할 것으로 생각 된다. 또한 어류 보호 측면에서 하상구조 변경 방지에 노력하여야 하며 어류의 서식처를 파괴하고 산란장 치어의 생활장을 방해하거나 강하성, 소하성 어류의 어로를 차단하지 말아야 하며, 본 지역을 하천 어류의 특정 보호 구역으로 선정하여 보호 대책에 구체적인 역점이 필요하며 관계 당국과 지역단체, 학술단체의 연계속에서 관심을 가져야 하며 점차 늘어가는 오염원에 대한 오염대책을 구체적으로 세워 시행하여야 한다고 판단된다. The ichthyofauna of Pyungchang River was investigated from October 1992 to June 1994 at 15 stations as shown in Fig. 1. Total number of species were 37species belonging to eight families. 17 of them(45.95%) were found to be endemic species of Korea. In this study Phoxinus oxcephalus and Cottus poecilopus were confirmed aboundantly inhabitant at the upper stream, and Zacco temmincki and Pungtungia herzi at the middle or lower reach of the river.<BR> The result indicate that the community structure of this area was very diverse and stable in species composition.
