A 18-year-old male patient presented with the skin colored, dome-shaped, soft, movable mass in his left retroauriculr region. The mass has slowly increased in size since birth. Histopathologic exarnination revealed sebaceous gland, eccrine gland and crosssectioned hair in the surrounding tissue, hair shaft projected into the lumen, and laminated horny material in the cyst. Transitional zone between stratified squarnous epithelium and the wall lined by histiocytes showed homogenous degenerative change. After surgical removal of the lesion, no recurrence was observed during 15 months of follow-up.

The effect of 0.25% and 0.5% Timolol on intraocular pressure and concentration in aqueous humor was studied after topical instillation in the white rabbit. The intraocular pressure was measured with pneuma tonometer and the Timolol concentration in aqueous humor was measured with High Preformance Liquid Chromatograph after fine needle aspiration of aqueous humor at various time intervals. The results were as follows; 1. The percentage reduction of intraocular pressure increased with time and reached a peak after 3 hours. 2. The concentration of Timolol in aqueous humor increased with time and reached a peak after 3 hours. 3. There was close correlation between intraocular pressure and Timolol concentration in aqueous humor.

Psoriasis has been known to have various humoral and cellular immune abnormalities. And adenosine deaminase (ADA) activities are known to be decreased in immune deficiency diseases. The present study was designed to measure the activities of ADA in sera and erythrocytes of psoriasis patients by Giustiss method. There were no significant differences in the erythrocytes ADA activities between normal subjects (9, Gp+4 43 units/10 cells) and psoriasis patients (7, 29+3. 64 units /10 cells). The ADA activities in sera of the psoriasis patients (13. 15+3. 43 units/ L) showed lowered activities than those of normal subjects (20. 44-2, 07 units/L).

PURPOSE: Diabetic macular edema is one of major causes leading to visual loss and it is difficult to be quantified. We investigated a volumetric quantification of retinal thickness change before and after focal laser photocoagulation with Heidelberg Retina Tomograph (HRT). METHODS: Ten patients who were diagnosed as diabetic retinopathy with clinically significant macular edema (CSME) in only one eye and treated with focal laser photocoagulation were studied. The opposite eyes which had no CSME were studied as control group. In the eyes which had CSME, the volume above reference plane (VARP) bounded by three consecutive circle centered at the fovea (diameter 1, 2, and 3 mm) were measured. The retinal thickness of control group was also measured with the same method. We performed focal laser photocoagulation for the eyes which had CSME and measured VARP at 1, 2, and 3 months after laser treatment. RESULTS: Three months after laser treatment, the VARP of treated eyes measured in each diameter was significantly decreased, however, there was no significant difference in control group. There was no significant difference in visual acuity change between before and 3 months after laser treatment. CONCLUSION: From the above results, we concluded that HRT could be used to quantify the change of diabetic macular edema before and after laser treatment.

Orthodontists want why the patients want orthodontic treatment. Demand and need for orthodontics is very important factors of cooperation and management. Chief complaint would be different according to the race and culture. Our results show that in the control group, Korean female adolescents[chief complaint is cowding(30.6%), spacing(26.5%), upper anterior protrusion(18.4%), anterior cross bite(8.2%) in order. Korean female adolescents considered anterior cross bite is more nonacceptable than spacing and anterior protrusion. The purpose of orthodontics seemed to enhance esthetic, dental health, and to improve oral function.

It is generally agreed that CT is a good staging method of renal cell carcinoma. However, CT has its ownpitfalls. Herein we reviewed 31 patients with renal cell carcinoma whose CT and pathologic stages were available.CT accurately staged 12 of 14 patients with Robson's stage I (86%), 6 of 8 with stage II (75%), 4 of 4 with stageIIIa (100%), 2 of 3 with stage IIIb (67%), and 1 of 2 with stage IV (50%). Overall staging accuracy of CT was 81%(25 of 31). CT failed to differentiate stage I and stage II in 4 cases. CT also failed to diagnose the microscopiclymph node metastasis in 1 case, and invasion of Gerota's fascia in another case. However CT was satisfactory indifferentiating surgically curable stage I to III from surgically incurable stage IV, and high reliable in thediagnosis of inferior vena caval thrombosis. Therefore it is suggested that CT is highly useful in determining thetreatment plan of renal cell carcinoma.

This study was designed to get the knowledges of the ideal arch form of the class I malocclusion patients of Koreans with first premolar extraction. The subjects consisted of 98 individuals with class I malocclusion with first premolar extraction. The results were as follows; 1. Author found the ideal arch shape of the class I malocclusion patients with first premolar extraction. 2. Equations of ideal arch form of the class I malocclusion patients with first premolar extraction were obtained from SPSS.
