Purpose: To evaluate the surgical results and clinical characteristics of congenital lacrimal fistula. Methods: Fourteen patients were diagnosed with congenital lacrimal fistula and received simple fistulectomy. Three patients received anterior lamella reposition operation simultaneously due to epiblepharon. We retrospectively reviewed the medical records and conducted telephone interviews. Results: In 15 eyes of the 14 patients, epiphora through lacrimal fistula disappeared. Two eyes of 2 patients showed a little epiphora only outdoors but there was no need of further treatment. All patients accepted the surgical results cosmetically. Histologically, stratified squamous epithelial change with keratinization was remarkable by aging. In adults, hair follicles with increased keratinization were contained and the result with skin was similar. Conclusions: Simple fistulectomy was a useful technique for congenital lacrimal fistula. 목적 : 선천성누루 환자의 임상양상과 수술 후 결과를 알아보고자 하였다. 대상과 방법 : 선천성누루로 진단된 환자 14명 15안을 대상으로 단순누루절제술을 시행하였고 이 중 3안에서는 덧눈꺼풀이 동반되어 덧눈꺼풀 교정술을 동시에 시행하였다. 수술 후 결과와 임상양상을 진료 기록지와 전화 설문을 통하여 후향적으로 분석하였다. 결과 : 14명 15안 모두에서 누루를 통한 눈물흘림의 증상이 소실되었고, 2명 2안에서 실외에서 약간의 눈물흘림이 있었으나 치료가 필요한 정도는 아니었다. 모든 환자에서 미용적으로 만족할 만한 결과를 얻었다. 조직소견은 나이가 들어감에 따라 중층편평 상피세포와 각질화가 증가하였고, 특히 성인에서는 모낭을 포함한 피부화가 두드러져 있었다. 결론 : 선천성누루 환자의 수술적 치료로 단순누루절제술을 시행함으로써 좋은 결과를 얻었다.

Purpose: This study nasolacrimal duct (NLD) stenosis in adult, evaluated the clinical results of treatment with topical 0.04% mitomycin C (MMC) eyedrops after silicone tube intubation. Methods: Prospectively, we analysed the clinical results from 29 eyes of 25 adult patients with epiphora due to NLD stenosis who underwent this procedure. Results: The mean follow-up periods was 9.3 months. Twenty-two eyes (76%) showed no epiphora and complete passing into the cavity by lacrimal irrigation. Four eyes (13.7%) showed intermittent epiphora but improvement relative to preoperative state. Three eyes (10.3%) showed persistent epiphora and no improvement. In total, 26 eyes (89%) showed improvement of symptoms. Complications were silicone tube prolapse in 5 eyes (17.2%) and dacryocystitis in 2 (6.9%) Conclusions: Silicone tube intubation with topical MMC eyedrops for treatment of patients with tearing due to NLD stenosis is effective, safe and easy. This technique can be tried before DCR if the surgeon has a thorough of nasal cavity anatomy and probing.

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.

In order to explore the detailed distribution of land snails inhabitated in Heongseong, this study was conducted for 2 years (from March 20, 1992 to March 20, 1994) for four optional areas. Total appearances of species were 3 order, 1 Families, 17 Genera, 22 species and total individuals were 3,009. the dominant species were Chamalycaeus cyclophoroides and Diplommatina (Sinica) paxillus. The stati of land snails on size were that there were, in Minute species, Carychium pessinum with 1.5mm shell height and 0.8mm shell diameter, in macro species Acusta despecta sieboldiana, Koreanohadra Kurodana, Aegista (Plectotropis) diversa with 11-21mm sell height, 20-28mm shell diameter. The height and diameter variation of Aegista (Plectoropis) diversa were bigger than anyone else. Also, Numbers of spiral were four to 10, and body colors were mainly white or brown. In terms of inhabitation area, data were gathered more than 14 areas. Among them, species which were inhabitated in the fallen leaves were shown 31.8%, 9-15.9% in stone wall, garden and farming field. Especially Cionella lubrica being known endemic species of Ulung Island was confirmed in Hoengseong.
