Many kinds of genetic changes have been known to be associated with malignant lymphoma and bcl-2, p53 and c-myc are some examples. We investigated the expression of p53 and c-myc protein in follicular and diffuse B cell lymphoma by immunohistochemistry to study the possible role of these proteins in the lymphomagenesis and transformation of the tumor. The rearrangement of bcl-2 oncogene and the immunoglobulin heavy chain gene was searched for in those cases by polymerase chain reaction(PCR). Paraffin-embedded tissues of fifteen follicular lymphomas and 14 diffuse lymphoma cases were used. The results of immunohistochemical staining are summarized as follows: 1) p53 positivity is significantly higher in diffuse lymphoma than in follicular lymphoma(P=0.001); 2) c-myc expression is not increased in diffuse lymphoma compared with follicular lymphoma; 3) PCNA index is significantly higher in diffuse lymphoma than in follicular lymphoma(P=0.03) but there was no statistically significant correlation between PCNA index and p53 positivity(P=0.44); 4) Eight out of 14 cases of follicular lymphoma and 12 of 14 cases of diffuse lymphoma showed rearrangement of the immunogloblulin heavy chain gene; 5) bcl-2 oncogene rearrangement was identified in only one case of follicular lymphoma and all the diffuse type lymphomas were negative in bcl-2/IgH rearrangement. In conclusion, assuming that the follicular pattern of B-cell lymphoma often transforms to diffuse type in later stages, c-myc over-expression might be an earlier event than p53 mutation in the process of tumor progression in B-cell lymphoma. bcl-2/IgH gene rearrangement in follicular lymphoma is a rare finding in Korea compared to that of Western countries.

For the purpose of ascertaining the status of physical growth and health status of the University students, a intensive survey was conducted by the authors towards a total of 2,638(male; 2,228, female;410) who passed the written entrance examination at the Seoul National University. The items included the measurements on physical growth, various physical indexes, visual acuity, tuberculosis and dental status. The findings and results can be summarized as follows : 1. Physical Growth. No signigicant difference was found in the physical growth between classes(literature and science) and by ages. In males, the means of body height, body weight, chest-girth and sitting height were 168.0+/-5.07cm, 55.7+/-5.71kg, 85.8+/-4.4cm and 91.5+/-2.21cm, respectively. In females, these were 157.4+/-4.57cm, 00.4+/-5.75kg, 80.3+/-4.51cm and 86.1+/-3.30cm, respectively. Basing on the above measurements several physical indexes were calculated as follows ; Relative body weigh 33.15 in males and 32.02 in females. Relative chest-girth 51.07 and 51.01, relative sitting-height 54.46 and 54.70 Rohrer index 1.00 and 1.02, Kaup index 1.97 and 2.04, Vervaeck index 83.63 and 83.03, and Pelidisi index 89.94 and 92.45. 2. Visual Acuity. Among the students of science classes those of 0.8 and below in vision on left and right occupied 46.4% and 45.0%, those of 0.6 and below 39.1% and 41.2%, respectively. Among the students of literature classes those of 0.8 and below occupied 46.3% and 42.9%, and those of 0.6 and below occupied 41.4% and 39.0, respectively. In males those of 0.8 and below occupied 46.8% and 44.5% and 0.6 and below occupied 41.9% and 39.7%, while in females 0.8 and below occupied 43.9%, and 42.4%, and 0.6 and below occupied 38.3%% and 37.3%, respectively. In males those of 0.8 and below in corrected vision occupied 12.1% and 10.3%, while in females 12.9% and 12.2%, respectively. More students of abnormal vision were found among science classes and the proportions of corrected vision were 38.9% and 37.4% in males, and 33.9% and 33.2% in females, respectively. 3. Tuberculosis. Among the total, 55 students were diagnosed as tuberculosis, of whom 50 were minimal cases, 2 were moderately advanced cases and 3 were far advanced cases. 4. Dental Status. Among the total, 81.2% were of decayed teeth, 20.8% filled, 9.5% missed, 5.0% extraction needed, 9.1% sunplatinum bridges, 3.3% golden bridges and 5.5% golden inaly. Regarding tartar on teeth moderate, heavy and light grades occupied 49.5%, 29.7% and 20.3%, respectively and 0.8% had none. 5. Comprehensive evaluation. According to the criteria 4 grades were applied to comprehensive evaluation as follows : A---excellent in physical status B---with some physical defects but no difficulties in study C---need treatment D---need treatment and rest. Out of the total, A grade occupied 21.6%, B 76.2% and C. and D 2. 2.

Injuries involving epiphyseal plate is important because of special problems in diagnosis, management and tl later complications of serious disturbance of growth which may be predictable and preventable. We revieviewed 40 cases of epiphyseal injuried in 35 patients, managed at Department of Orthopaedic Surgery, Nation Medical Center from Jan. 1975 to Dec. 1981. The longest follow up was 4 ywars and 6 months and the shortest, year, the average being 2 years. The results were as follows: 1. The incidence of epiphyseal injuries was 35 patients in 211 patients of padiat.c fractures. 2. There were 29 males and 6 females. 3. The causes were falling down accident, slipping down accident, impinging injury, direct blow and traff accident in order 4. Roentgenographically, 23 cases were Type II of Salter & Harris classification, 8 cases were Type IV, cases were Type I, 2 cases were Type III, and 1 case was Type V. 5. Epiphyseal Injuries were found with order of decreasing frequency of distal radius, distal humerus, dist femur, phalanges, distal tibia, proximal humerus, distal fibula and proximal humerus. 6. The methods of treatment were C/R & 'cast immobilization, C/R & K-wire fixation, 0/R & K-wire fixation and C/R & screw fixation. 7. Complications were found in 2 cases of angular deformity in Type IV injury, 1 case of shortening in Type injury, and 1 case of angular deformity in Type V injury.

BACKGROUND: Laser resurfacing has beneficial effects for the treatment of several skin conditions. Recently, the pulsed erbium:YAG laser has been shown to be a highly effective treatment for several kinds of pitted facial scars. OBJECTIVE: The purpose of this study was to assess the efficacy and safety of pulsed erbium:YAG laser skin resurfacing at the setting of low or high energy for pitted acne scars. METHODS: 65 patients with pitted acne scars were included in this study. All patients had skin types III or IV. All patients were instructed to use tretinoin cream 0.05% nightly for 2-4 weeks prior to the laser treatment. The pulsed erbium:YAG laser with a 2 mm handpiece at the setting of 500 mJ/pulse, 3.5-5 W in 45 patients and 1,000 mJ/pulse, 7-10 W in 20 patients was used. Two weeks after laser treatment, topical application of hydroquinone 4%, tretinoin 0.05%, and hydrocortisone 1% cream was recommended for 2-4 weeks. Facial photographs were obtained at baseline and 2 week intervals postoperatively. The results of treatment were evaluated for the changes of skin texture and color at 1 month, 3 months, and 6 months. RESULTS: In 45 cases treated with 500 mJ/pulse energy, pitted acne scars were improved about 46.7 % on average and no erythema and postinflammatory hyperpigmentation was observed after 6 months. In 20 cases treated with 1,000 mJ/pulse energy, pitted acne scars were improved about 64% on average and erythema in two patients and postinflammatory hyperpigmentation in one patient were observed after 6 months. CONCLUSION: The results of laser treatment for pitted facial acne scars at the setting of high energy are better than those of laser treatment at the setting of low energy.

OBJECTIVE: We report here on two cases of pseudoaneurysms that were diagnosed using computed tomographic angiography (CTA), with one arising in the superficial temporal artery and the other arising in the occipital artery. METHODS: Case 1: A 29-year-old man presented with a slow growing, pulsatile mass on the left side of his forehead following a blow from a fist 10 days earlier. CTA revealed an 11 x 8 x 11-mm oval pseudoaneurysm arising from the frontal branch of the left superficial temporal artery. Case 2 : A 36-year-old man presented with a pulsatile mass in the right suboccipital region that had been present for the past year. He had no history of direct trauma. CTA revealed a 15 x 8 x 13-mm oval dye-filled sac arising from the right occipital artery. RESULTS: Based on the CTA images, the parent arteries were exposed and ligated proximally and distally to the pseudoaneurysms and then they were completely excised. CONCLUSION: CTA is a minimally invasive technique for making the diagnosis of scalp pseudoaneurysms and CTA is also useful for the preoperative planning.
