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.

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.

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.

Majocchi's disease is one of chronic vascular disorders of the skin, histologically showing capillaritis with lymphoid cell infiltration. Although the hypothesis of delayed type hypersensitivity reaction against foreign antigen is proposed as the mechanism producing this condition, there are much yet to be defined. We tried to examine the lesional skin of five patients with Majocchi's disease by the direct immunofluorescence with anti-human immunoglobulins, C 3, and fibrin. As a result we found the deposition of immunoglobulins (M, and G) in papillary blood vessels in four patients, and C 3 and fibrin were found in all five patients. C3 was also found at the dermoepidermal junction in three patients. These findings suggest the posssibility that antibody mediated immunologic processes may alsobe involved in the pathogenesis of this disorder. With this observation Majocchis disease could be considered as a chronic immune vasculitis.

Cardiac relaxation is impaired in many cardiac disorders and is the subject of extensive investigation. Though measurement of isovolumic relaxation time ought to prove a simple means of quantifying such abnormalities in clinical practice, the problem of defining the timing of mitral valve opening at the onset of ventricular filling has been a difficulty. previous studies have used the 'O' point of the apexcardiogram, but more recently it has been shown that this may be open to considerable error. It was the purpose of the present study to determine the duration of true isovolumic relaxation and the factors influencing its duration, and to evaluate its use as a simple noninvasive measurement of cardiac dynamics in terms of the present approach. True isovolumic relaxation time (IRT) was measured noninvasively from the onset of the aortic component of the second heart sound to the onset of rapid opening of the mitral leaflets from simultaneous recording of echocardiogram, phonocardiogram, electrocardiogram and carotid tracing in 60 normal subjects, 30 male and 30 female and in 50 with hypertension, 28 male and 22 female ranging in age from 20 to 45 years. 1. The duration of IRT was 53.6+/-9.9 msec in normal subjects with no relation to sex. 2. IRT was related to heart rate, systemic blood pressure, and systolic and diastolic time intervals. 1) IRT tended to decrease with increasing heart rate and a regression equation for predicting it in relation to heart rate was 'IRT(msec)=88.97-0.466xH.R.(beats/min)' (P<0.01). 2) IRT tended to increase with increasing systemic blood pressure and a regression equation for predicting it in relation to aortic closing pressure was 'IRT(msec)=5.09+0.459xaortic closing pressure(mmHg)' (P<0.01). IRT was prolonged in patient with hypertension. 3) IRT was in close relation to left ventricular contraction indices such as preejection period(PEP), isovolumic contraction time and preejection period/left ventricular ejection time ratio. 4) There was no relation between IRT and left ventricular pump performance indices such as stroke volume, ejection fraction, fractional shortening and left ventricular dimension. 5) There was strong association between IRT and diastolic time intervals. Authors were impressed through this study that IRT is a useful measurement of left ventricular dynamics in early diastole.

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.
