The clinical review was done on 17 cases with the foreign body in the upper gastrointestinal tract who underwent endoscopic removal of foreign body at Kang Nam Sacred Heart Hospital from Dec. 1981 to Dec. 1991. The results were as follows: 1) The age distribution varies from 3 months to 72 years of age, being most prevalent under 5 years of age. 2) The incidence of foreign body in the order of frequency was coin, fish bone, safety pinring, peanut, keyring, food bolus, artificial teeth and medal. Among 17 cases, 9 cases(53.0%) were lodged in the esophagus and 8 cases(47.0%) were lodged in the stomach. 3) Dysphagia or globus was the common symptom in 8 cases(47.2%), followed by absence of symptom in 7 cases(41.2%), upper abdominal discomfort in 1 case(5.8%) and vomiting in 1 case (5.8%). 4) l0 cases(58.8%) of foreign body were removed within 72 hours and 7 cases(41.2%) of foreign body were removed after 72 hours.

Congenital pulmonary lymphangiectasis is a rare cause of severe respiratory distress in the newborn period and most of these patient die, usually within the first 24 hours of life. The light microscopic characteristics of the lungs are a network of partly tubular, partly cystically enlarged lymph vessels within large areas of connective tissue and they have thin wall lined by endothelium. Also congenital pulmonary lymphangiectasis is closely associated with cardiovascular malformation, and most frequently occurs in the clinical setting of congenital heart disease with or without pulmonary venous obstruction(total anomalous venous return, atresia of large pulmonary veins) The authors describe three typical cases of congenital pulmonary lymphangiectasis.

A 56-year-old woman presenting a 10-year history of atrophic discoid patches with underlying subcutaneous nodules was seen. These skin lesions were distributed on the upper arms bilaterally. Biopsy specimens taken from the lesional skin showed epidermal and dermal changes consistent with the discoid lesions of the cutaneous lupus erythematosus. Deep dermis and subcutaneous fat tissue revealed sclerosis and fibrinoid alterations of the collagen and necrosis of fat cells, the features corresponding to the lupus ei ythematosus profundus. She had no laboratory evidences suspective of systemic lupus erythematosus or other connective tissue diseases. This patient with lupus erythernatosus profundus which cleveloped subsequent to the discoid lesion is consiclered to be a rarely encounteririg observation in lupus erythematosus.

Service diversification is recognized as an important strategy against turbulent environmental change. This study is designed to find out the trend of service diversification in Korean health care organizations and also to identify factors associated with the degree of service diversification. Data were collected from 69 hospitals out of 71 hospitals with over 300 beds. Important findings are summarized below. 1. Types of diversification are closely related to hospital size. Large hospitals have a tendency to provide sophisticated service requiring specialized skills and equipment, while small hospital have concentrated their efforts on health screening programs. 2. The more competitive and bigger hospitals are, the greater number of services that provide. Also, hospitals operating rational management information systems provide more services. Contrary to the expectation, hospitals with a low performance during last 3 years showed more service diversification. 3. A trend of more diversification was observed in hospitals whose chief executive officer used a prospector strategy. 4. A multiple regression analysis revealed that bed size, competitive environment, degree of rational management, and the growth pattern were significantly associated with teh service diversification.

A case of benign lichenoid keratosis(BLK) developed in a 25-year-old female is presented. She had two erythematous plaques with slightly verrucous surfaces on the lips for 4 weeks. A biopsy specirnen taken from the periphery of the lesion revealed a focal parakeratosis, the absence of granular cells, and hydropic degeneration of the basal cells in the epidermis. The upper dermal infiltrate composed chiefly of lymphacytes intermingled with a few histiocytes was also seen. The direct immunofluorescent study showed depositions of a few cytoid bodies and fibrin around the areas of the dermoepidermal junction. These plaques on her lips, demonstrating lichenoid tissue changes, cleared in 8 weeks from the evalution, without any treatment.

Lichen planus is rare in Korea. and oral lichen planus is even rarer. To our knowledge, this is the first case reporting in Korean dermatological literature. 57 year-old man was seen for erythema with white striation on the oral mucosa in December 1981. The initial lisior s appeared on the buccal mucosa of left side of oral cavity 10 months ago. Thereafter he noticed similar lesions on the right side of buccal mucosa, hard palate, left side of upper and lower gingiva and left side of the lower lip. Histopathological and direct immunofluorescence studies showed typical features of lichen planus. Administration of griseofulvin(0.5gm. of Fulvicin' daily) for 4 weeks resulted in no clinical improvement. Oral retinoid(25mg of Ro 10-9359 daily) for 11 weeks resulte3 in healing of lesions with no side effect except slight dryness of the mouth.

Reticulated pigrnented anomalies of the flexures is a pigmentary disorder bearing genetic back ground, also known as Dowling Degos disease or dark dot disease. It is characterized reticulated brownish black macules on the flexural areas with the histological features of filiform pigmented epidermal downward proliferation and the presence of intraepidermal keratin containing cysts. We report 34-year-old housewife who showed brawnish black reticulated macules on her axillae, anterior neck and genitocural folds. Pigmented comedones were also found at the marginal areas of the axillae. Biopsy specimen revealed the presence of intraepidermal keratin containing cysts and basilar hyperpigmentation.

BACKGROUND: Uracil nucleotides are stored in platelets and all other cells, and are released into the extracellular space upon stimulation. They show various biological responses but their actions and mechanism are not well understood. This study was conducted to investigate the effects of uridine 5'-triphosphate(UTP) on vascular tone and to identify the characteristics of their receptors. METHODS: Aortic ring preparation were made from the rat descending thoracic aorta. Endo-thelial cells were preserved or removed by gentle rubbing, The basal tension of aortic ring was lgm and isometric contraction were recorded on polygraph using force transducer. RESULTS: In aortic ring Precontracted by 100nM norepinephrine, UTP induced dual effect with various concentrations. UTP elicited endothelium-dependent relaxation at low concentrations(100nM-10microM), and endothelium-independent contraction at high concentrations(more than 30microM). Among uracil nucleotides, UDP was as much effective as UTP in vascular tone, but UMP and uridine were not. UTP(pA50 6.15) was more potent than ATP(5.17), ITP(4.75) and other nucleotides(TTP, GTP, CTP). At basal tension, UTP induced relaxation at low concentrations and contraction at hige concentrations in endothelium-intact ring. But in endothelium-removed ring, UTP elicited only contraction. Prior treatment of aortic ring with suramin, a non-selective P2-purinoceptor blocker, inhibited UTP-Induced relaxation and contraction. Reactive blue-2, a P2gamma purinoceptor blocker, inhibited relaxation only, but alpha, beta-methylene ATP, a P2x Purinoceptor blocker, enhanced contractile response. ATP inhibited the UPT-induced relaxation, but 2-methylthio ATP did not alter the effects of UTP. It means that UTP and ATP act at the same receptor but 2-methylthio ATP does not. CONCLUSION: These results suggest that UTP-induced relaxation is mediated by nucleotide receptors on endothelium and the contraction is mediated by pyrimidinoceptors on vascular smooth muscle.
