Although the psoralen therapy has been used extensively on vitligo since the : introduction by El-Mofty on 1948, the result has not been satisfactory. Recent investigations showed that the autoimmune mechanism might be the causative factor to the development of vitiligo, and the use of steroid might be expected to be beneficial in the treatment of this disorder. Authors tried the combined treatment of prednisolone and psoralen on vitiligo and the results obtained are as follows; 1. Repigmentations began to develop from injected area of prednisolone as well as frorn hair follicles and peripheral area of the lesions. 2. More satisiactory responses were obtained on the widespread and symmetrical lesions of shorter duration than on the lesions of localized and long duration.

E-cadherin is a calcium-dependent epithelial adhesion molecule which plays a role in the initial step of invasion of cancer cells. The step that follows the migration of separated tumor cells is a proteolytic lysis of basement membrane and extracellular matrix by protease of epithelial and endothelial cells such as matrix metalloproteinase (MMP). Vascular endothelial growth factor (VEGF) is known to be an endothelial cell-specific powerful mitogen as well as a vascular permeability factor. This study is aimed to evaluate the correlation between expression of these factors and pathologic or clinical variables and the roles and prognostic significance of those factors in squmous cell carcinoma and adenocarcinoma of the lung. Immunohistochemical stains were performed for E-cadherin, MMP-2, and VEGF in surgically resected specimens from 90 patients with squmous cell carcinoma and adenocarcinoma of the lung. Mean age of the patients was 59.7 years. Histologic type was categorized into 56 cases of squamous cell carcinoma and 34 cases of adenocarcinoma. Mean survival period of the 35 patients was 54 months. The immunohistochemical stains for E-cadherin, MMP-2, and VEGF revealed positive reaction in 67 cases (74.4%), 43 cases (47.8%), and 34 cases (37.8%), respectively. The expression of E-cadherin was higher in adenocarcinoma (82.4%) than in squamous cell carcinoma (69.6%). MMP-2 was expressed in the tumor cells, especially those invading into the surrounding stroma. The expression of MMP-2 was significantly correlated with the survival rate (p<0.05). The expression of VEGF in the tumor cells was significantly higher in cases with lymph node metastasis (p<0.05). In conclusion, these findings suggest that the expression of MMP-2 and VEGF predict poor prognosis of patients with squmous cell carcinoma and adenocarcinoma of the lung and that VEGF may play a role in tumor metastasis.

Chemically induced epiderml carcinogenesis is usually divided into two stages, the initiation and promotion. The initiation involves conversion of some epidermal cells into latent neoplastic cells and the promotion is proliferation of the transformed cells. As immunosurveillence is thought to be a host defense against tumors, Langerhans cells, being essential in initiation of local cutaneous immunologic reaction, is suggested to be important in the carcingenesis of the epidermis. This study is attempted to investigate the epidermal proliferative changes in mice induced by application of 12-0-tetradecanoy1-phorbol-13-acetate(TPA) on the skin initiated with 7, 12-dimethylbenzanthracene(DMBA) and its relationship with Langerhans cell. Ninty five male inbred BALB/c mice weighing 20~25 g were divided into five groups; the 33 week-group, the 21 week-group, the 12 week-group and the 4 week-group according to the duration of carcinogen application, and the control group. The carcingen was applied with a brush on the dorsal skin of mice after depilation. Ten days after application of 800 nmole DMBA in 0.4 cc acetone, 20 nmole TPA in 0.4 cc acetone was applied twice per week and the control group was applied with the same amount of acetone for 4 weeks. Animals were sacrificed 3 days after the last application of TPA. One hour before sacrifice, bromodeoxyuridine(BrdU) (1 mg/g) was injected via the tail artert for BrdU stain of S phase cells. A strip of dorsal skin was used for hematoxylineosin stain, immunohistochemical stain for BrdU and la antigen of Langerhans cell, and flow cytometry. The results are as follows: 1. Cellular proliferation, hyperkeratosis and dysplasia of the epidermis were increased in relation to duration of carcingen application. Papillomas were developed 12 weeks after application of the carcingen. 2. BrdU labelling and proliferative indices of the 20 weeks' application group were significantly higher than those of the 12 weeks' application group. The number of Langerhans cell was decreased markedly ater 4 week' application of the carcinogen. 3. All epiedrmal lesions including a case of squamous cell carcinoma were diploidy in flow cytometry. It is thought that disturbance of immunosurveillence, caused by depletion of Langerhans cell, may permit proliferation of epidermal cells. Although abnormal quantitative change of nuclear DNA has not occurred even when the epidermal proliferative activity and dysplastic change were increased markedly, it is thought that the occurrence of structural change of chromosome is remained to be clarified.

Disfiguring hyperpigmentation of the exposed areas may have impartant and lasting effects on the emotional well-being of the patient. And many attempts to treat areas of hyperpigmentation have been earried out, but all of them are not very successful. Recently 4-isopropylcatechol has been known to inhibit melanin pigmentation with a selective action on melanocytes either destroying or inactivating the melanocytes experimentally. There is no report on its clinical trial till now. In this study, 1% 4-isopropylcatechol cream was topieally applied to the hyperpigmented lesions of 29 patieots of melasma, freckle, and cafe-au-lait spot. The bleaching effect on meiasmas was very satisfactory in all patients but coantact dermatltis in 3 patients and reticular hyperpigmentation with areas of depigmented spots in one patient were developed as the side effects of the drug. Freckle and cafe-au-Iait spots were not bleached.

To assess the safety of playground equipments in the elementary schools of Taegu, a site visit was made to 117 elementary schools out of 119 schools between 1st and 30th April 1991. Safety criteria were developed on the bases of Massachusetts' Playground Safety Check List, standard height of Korean children of 6-12 years old, and source book for designing playground equipments. There were eleven different kinds of playground equipments installed in 117 schools but the number of equipments was about 50-60% of the minimum requirement set by the Ministry of Education except chin-up bar. Among the installed equipments, 47.3% of swings, 16.6% of parallel bars, 20.0% of monkey bars, and 16.0% of slides were broken down. None of the swings, slides, seesaws, monkey bars, and sandboxes met the safety criteria to the full but 59.0 of chin-up bars, 31.4% of parallel bars, and 13.5% of stumps met the criteria fully. The proportions of equipments that were dangerous for children to play on were 26.4% for slides, 20.0% for monkey bars, 11.6% for seesaws, 10.4% for parallel bars, 9.85 for sandboxes, 7.4% for swings and stumps, and 3.9% for chin-up bars. The rests were either in need of repair of broken down. It was revealed by this survey that the playground equipments were too short in number to meet the minimum requirement, designs and size were not standardized, and many of the equipments were involved with the risk of child accidents. Therefore, a safety standard for the playground equipments should be developed and the existing equipments should be repaired immediately.

Primary aldosteronism is present in approximately 1% of unselectd hypertensive patients. Adrenal adenoma is a known as one of the surgically curable form of the hypertension. Hypertension is one of the contributing factors for the development of aortic dissection. Cincurrence of aortic dissection in patient with primary aldosteronism is extemely rare. Only one case wasconfirmed by autopsy and reported in the world literature. We report a case of DeBakey type 3 anortic aneursm in a 49-year old hypertensive female patient with primary aldosteronism due to left adrenal adenoma. She underwent left adrenalectomy uneventfully after stabilization of her blood pressure with maximal medical management including nitroprusside, aldactone, enalapril and inderal.

Jehovah's Witness patients who require an operation represent a challenge to the physician because of the patients' refusal to accept a blood transfusion. We report 5 years experience with a consecutive series of 12 Jehovah's Witness patients in the Obstetric & Gynecological department who underwent operation. In 12 cases, death ensued in one patient who underwent subtotal hysterectomy for ectopic pregnancy. The cause of death was severe anemia & complicated respiratory problems. We discussed the problem of elective & emergency operations on Jehovah's Witness patients. Anesthesiologists must understand legal aspects, as well as and ethical, if they are to conduct their practice as an art as well as science.
