1.Study about the Natural Growth Rate of Hepatocellular Carcinoma Using Follow-up CT Examinations(1):Preliminary Report.
Journal of the Korean Radiological Society 1994;30(4):711-716
PURPOSE: To make the guideline for diagnosis and treatment policy of various hepatocytic nodular lesions detected during the imaging diagnosis of cirrhotic liver and to get our own data about hepatocellular carcinoma based on Korean patients. MATERIALS AND METHODS: We retrospectively reviewed 40 confirmed hepatocellular carcinomas foilwed up with CT more than once without any treatment. Total numbers of follow-up were 50. First, we input the data of initial and follow-up diameter visible on CT images and follow-up interval of each mass to the computer, and got the mean growth rate curve and growth curve of hepatocelluiar carcinoma using a program of Quattro-pro, one of the spreadsheet. And then the doubling time was also calculated using Schwarz's formula. RESULTS: According to the growth rate curve, the tumor under 3 cm in diameter showed relatively show growing pattern but the one above 3 cm in diameter showed rapid growing pattern. Mean growth curve also showed rapid turning point around 3 cm. Overall mean doubling time was 82 days(mean +/- SD = 82.3 +/- 56.2): 119 days in the tumors smaller than 30 mm in diameter, 69 days larger than 30 mm in diameter. CONCLUSION: Hepatocellular carcinoma'is relatively slowly growing tumor and shows rapid increase of its growth rate when it is larger than 30 mm in diameter as a turning point. We think that this fact could make an important role to determine the treatment policy of various hepatocytic nodular lesions suspecting hepatocellular carcinoma.

2.IV-gamma Globulin Therapy for Severe Abdomlnal Pain Refractory to Steroid Therapy in Henoch-Scholein Purpura.
Journal of the Korean Society of Pediatric Nephrology 1997;1(2):176-178
To make the objective standard of nuclear size in grading nuclear pleomorphism of invasive ductal carcinoma of the breast, we measured maximal nuclear diameter of tumor cells on imprint cytology slides and histologic sections from 65 cases by using computer-based image analysis system (Optimas 6.0). The maximal diameter of red blood cells were also measured to evaluate the ratio of maximal nuclear diameter of tumor cells to maximal diameter of red blood cells. The mean values of maximal nuclear diameter of tumor cells on imprint cytology slides and histologic sections were 7.56microgram, 7.53microgram in nuclear grade 1, 8.92+/-0.98microgram, 9.02+/-0.74microgram in nuclear grade 2, and 12.90+/-1.47prn, 12.44+/-1.41microgram in nuclear grade 3, respectively. There were no significant differences between values of imprint cytology and histologic section. The ratio of maximal nuclear diameter of tumor cells to maximal diameter of red blood cells were 1.3-1.4:1 in nuclear grade 1, 1.6-1.7:1 in nuclear grade 2, and 2.2-2.3:1 in nuclear grade 3. Ths would be guidelines for grading nuclear pleomorphism of invasive ductal carcinoma of the breast on routine surgical pathology work.

4.An Experimental Study of the Effect of Bone Cement upon the Epiphyseal Plate of Growing Rabbits
The Journal of the Korean Orthopaedic Association 1979;14(2):309-313
Acrylic bone cement is now widely used in surgery for many purposes. Therefore, the effect of bone cement on the growth plate of a growing bone may be an interesting subject, particularly in the orthopedic field. The authors carried out an experiment to study the effect of bone cement on the growth plate of the bone, using 32 growing rabbits weighing from 800 to 1000 gm, which were divided into 2 main groups. In Group I, which was the control group, the growth plates were injured mechanically by inserting a Kirschner wire and a stainless screw, 1.5 mm and 2.5 mm in diameter, respectively, which were then removed. In Group II, the growth plates were also injured by the same method as in Group I, and bone cement was inserted into the holes made by the insertion of the Kirschner wire and the screw. Then the histological findings of the injured plates were studied at 2, 4, 6 and 10 weeks after injury. Following observations were made. 1. In Group I, in which the growth plates were only mechanically damaged, the histologic changes were localized only in that portion of the plate which had been injured by a wire or a screw, leaving the rest of the plate relatively normal. In Group II, the extent and severity of the injury were more wide and severe. 2. Proliferation of mesenchymal fibroblasts and deformity of the growth plate were more severe in Group II. 3. In both groups the extent and severity of growth plate injury were more marked when injured by a screw.

The stature, span, lower limb length, sitting height, head length and head breadth of 411 Korean elementary school girls ranging from 7 to 10 years of age were measured biometrically and the indices among all of the items were calculated to investigate the physical growth status. The following conclusion have been obtained. 1. The average statures were 117.40cm in 7, 122.72cm in 8, 126.76cm in 9 and 132.92cm in 10 years of age groups, and the annual average stature growth was 5.17cm. 2. The average spans were 113.12cm in 7, 118.70cm in 8, 124.26cm in 9, 130.46cm in 10 years of age groups, and the annual average span growth was 5.78cm. 3. The average lower limb lengths were 62.96cm in 7, 66.80cm in 8, 69.09cm in 9 and 73.13cm in 10 years of age groups, and the annual average lower length growth was 3.39cm 4. The average sitting heights were 65.82cm in 7, 68.56cm in 8, 70.18cm in 9 and 73.13cm in 10 years of age groups, and the annual average sitting height growth was 2.43cm. 5. The average body weights were 21.22kg in 7, 24.13kg in 8, 25.54kg in 9 and 29.27kg in 10 years of age groups, and the annual average body weight growth was 2.68kg. 6. The average head lengths were 16.29cm in 7, 16.38cm in 8, 16.47cm in 9 and 16.60cm in 10 yeras of age groups, and the annual average head length growth was 0.10cm. 7. The average head breadth were 14.50cm in 7, 14.65cm in 8, 14.67cm in 9 and 14.81cm in 10 years of age groups, and the annual average head breadth growth was 0.10cm. 8. While both relative span and lower limb length increased with age and the relative sitting height slightly decreased with age. 9. The relative body weight increased with age. 10. The head type depended on cephalic index was belonged to hyperbrachycephaly, and showed no differrences with age in all of the groups. 11. The relative span was over 96 in all age groups, and the value increased slightly with age. 12. The average annual growth showed remarkable high value between 9 to 10 years of age in the items of stature, span, lower limb length, sitting height and body weight.

We report a 44-year-old female patient with Eosinophilic cellulitis who had developed pruritic erythematous plaque on the right lower abdomen since two months ago. The blood eosinophil count was 2,066/mm at first visit. This lesion responded well to cortieosteroid therapy. However new erythematous swelling reappeared on the left lower abdomen and left inner thigh 3 months after the first treatment. A biopsy specimen taken from an erythematous plaque showed many flame figures and diffuse infiltration of eosinophils and histiocytes in the lower dermis and subcutaneous fat tissue.
