Cheilitis granulomatosa is one of the rare dermatoses which is characterized by a sudden onset and a progressive course termination in chronic enlargement of the lips Usually, enlargement of lip is the only symtom without ulceration, fissurign or scaling. It may be considered a part of the Melkersson-Rosenthal syndrome and the etiology is still unknown. A 35 year old female with the clinlcal symptoms of cheilitis granulomatosa is presented; the diagnosis was confirmed by histopathologic study.

INTRODUCTION: The pathophysiology of PIH remains unclear. Recently, placental abnormalitiesare stressed as a possible cause of PIH. Abnormal shallow invasion of trophoblasts, confinedto decidua, without involving myometrium is believed to result in reduced uteroplacentalperfusion, endothelial injury, and activation of coagulation cascade system. Integrin, one of theadhesive membrane proteins, is expected to be related to the regulation of trophoblasts invasion. PURPOSE: The purpose of this study is to investigate the expression of adhesion moleculesin placenta and the correlation between uterine artery Doppler findings and integrinexpressions in the placentas of PIH patients. SUBJECTS: Thirty-six cases of severe PIH patients were enrolled in the study with 10number of normal control pregnant women. The integrin subunit expressions withimmunohistochemical staining were observed in floating villi, maternal-side cytotropholbasts, andfetal-side cytotrophoblasts. Uterine artery Doppler study was also performed, and the S/Dratio was evaluated. Abnormal Doppler findings was defined as S/D ratio>or=2.6. RESULTS: Cytoplasmic staining of villi and placental bed cytotrophoblast for theintegrin alpha1 subunit in PIH specimen was weaker than those in normal controls. Theexpression of integrin beta1 subunit was negative for both controls and PIH group. Thepositive cytoplasmic stain was observed among PIH placenta in contrast to normal control inwhich the expression of integrin beta4 subunit was not detected. The expression of alpha v beta3 introphoblast with PIH was positive staining, but not in control group. Uterine artery Dopplervelocimetry was performed in 25 cases with PIH. Trace(+/-) or - staining of integrin alpha1 subunit were observed in 60.0% of abnormal S/D(>or=2.6) group, 20.0% of normal S/Dratio group patients, respectively. Trace or + staining of integrin beta4 subunit were observedin 50.0% of abnormal S/D group and 6.7% of normal S/D group and this is in statisticallysignificant. Trace or + staining of integrin alpha v beta3 subunit were observed 70.0% ofabnormal S/D group and 26.7% of normal S/D group, and this statistically significant. CONCLUSION: In PIH the abnormality in the invasion of cytotrophoblats results inabnormal integrin subunit expression, but it is also correlated to the abnormal uterine arteryDoppler velocimetry which shows a S/D ratio of greater than 2.6. Thus, the uterine arteryDoppler velocimetry reflects abnormal placentation.

BACKGROUND: There have been only a few electron microscopic studies after laser treatment of pigmented skin lesions. OBJECTIVE: The purpose was to investigate the pathologic, immunohistochemical, and electron microscopic changes following Q-switched alexandrite laser treatment of pigmented skin lesions. METHODS: Three patients with acquired bilateral nevus of Ota-like macules, and 2 patients with cafeau lait macule were irradiated with Q-switched alexandrite laser. Forty biopsies were taken before and immediately after laser treatment. Hematoxylin-eosin, Fontana-Masson, and gp100 staining were performed for the evaluation of the histopathologic and immunohistochemical findings of the specimens. Electron microscopic findings were also evaluated. RESULTS: Histopathologically, suprabasilar separations were observed immediately after laser treatment. Vacuolar alterations of pigment-containing cells were frequently found in the epidermis and/or in the dermis. Fontana-Masson and gp100 staining positivity changed to negative or decreased in the epidermis immediately after laser treatment, while they changed to negative in the dermis. Ultrastructurally, epidermal pigment-containing cells frequently showed severe vacuolar changes in the cytoplasm, pyknotic nuclei, and vacuolated and/or fragmented melanosomes immediately after laser treatment. Dermal melanocytes frequently revealed vacuolated and/or fragmented melanosomes immediately after laser treatment. CONCLUSION: Histopathologic, immunohistochemical, and electron microscopic examination of pigmented skin lesions immediately after Q-switched alexandrite laser treatment demonstrated vacuolated or fragmented melanosomes and vacuolar alteration of pigment-containing cells in the epidermis and/or in the dermis, which suggested selective photothermolysis of melanosomes.

Arteriovenous malformation is a vascular anomaly due to the hamartomatous proliferation of the subpapillary vascular plexus which exhibits multiple arteriovenus shunts. Various tumors can be developed in the port-wine stain, such as, pyogenic granuloma, basal cell carcinoma, squamous cell carcinoma, tufted angioma, giant proliferative hemangioma, and lymphangioma circumscriptum. We report a case of arteriovenous malformation arising in the port-wine stain. The pathogenesis of development of arteriovenous malformation in the port-wine stain is still unknown, but may be related to localized exaggerations of ectasia.

To evaluate the effect of alteration of left atrial pressure. volume and wall tension on the circulating plasma level of atrial natriuretic peptide(ANP), 15 patients with left atrial hypertension due to mitral stenosis were studied at the time of percutaneous balloon mitral valvuloplasty(PMV). Hemodynamic measurements and plasma atrial natriuretic peptde levels were obtained before, immediately(5-10min) after and 24h after valvuloplasty, and echocardiographic left atrial size, wall tension and mitral valve area were measured bdfore and 24h after valvuloplasty. 1) Immediately after valvuloplasty, left atrial pressure, pulmonary atrial pressure and mean diastolic pressure gradient across the mitral valve decreased, and the mitral valve area by Gorlin's method increased, significantly. Plasma atrial natriuretic peptide level(atright and left atrium, pulmonary artery and aorta) rose significantly after balloon inflation. This rising may reflect a transient increase in left atrial pressure and volume expansion associated with mitral valve occlusion by balloon. 2) Twenty four after valvuloplasty, mitral valve area increased, and left atrial volume and wall tension decreased, significantly. Plasma atrial natriuretic peptide level(at right atrium, pulmonary artery and aorta) fell significantly, too. In conclusion, change of plasma atrial natriuretic peptide le.vel before and after percutaneous balloon mitral valvuloplasty reflect hemodynamic alteration of right and left atrium.

Five years ago, we made the cut-off value of Tsh by dry filter paper method as 15 microU/ml to sereening congenital hypothyroidism. Since then, 1,210 term neonates, who had no perinatal problems, were born in SNUCH between Aug. 1987 and Apr. 1992, had been performed this neonatal Tsh screening test with this cut-off point. Neonates had been recalled for measurement of serum T4/TSH to rule out congenital hypoothyroidism if their TSH value by screening tests reveal more than 15 microU/ml. Because there had been high false-positive rate during 5 years, we felt thiscut-off value of TSH should be set higher than 15 microU/ml with same method. Therefore, we analyzedthis TSH values to set a new cut-off point to recall the neonates. The results ars asbelow: 1) TSH value by dry filter paper method was 8.48+/-4.41 U/ml(mean+/-S.D.) 2) Assuming 15 microU/ml as a cut-off point for recall the neonates, the false positive fate is 8.01% 3) Tomake the false positive rates as 0.3%, it is reasonable to set the cut-off point at 22 microU/ml, whichis +/-3S.D.(99.7 percentile) of measured TSH level by dry filter paper method.

The purpose of the present study was to investigate the effect of ethanol extracts from red pepper seeds on the antioxidative defense system and oxidative stress in rats fed a high fat . high cholesterol diet. Rats were divided into four experimental groups which were composed of high fat . high cholesterol diet group (HF), high fat . high cholesterol diet with 0.1% ethanol extracts from red pepper seeds supplemented group (HEA), high fat . high cholesterol diet with 0.2% ethanol extracts from red pepper seeds supplemented group (HEB) and high fat.high cholesterol diet with 0.5% ethanol extracts from red pepper seeds supplemented group (HEC). Supplementation of ethanol extracts from red pepper seeds groups (HEA, HEB and HEC) resulted in significantly increased activities of hepatic glutathione peroxidase and catalase. Hepatic superoxide radical contents in microsome and mitochondria were significantly reduced in the groups supplemented with red pepper seeds ethanol extracts. Hepatic hydrogen peroxide content in the mitochondria was reduced in ethanol extracts from red pepper seeds supplemented groups. TBARS values in the liver were reduced in red pepper seeds ethanol extracts supplemented groups. Especially, HEB and HEC groups were significantly decreased compared to the HF group. Hepatic carbonyl values were significantly reduced in mitochondria in these supplemented groups. These results suggest that red pepper seeds ethanol extracts may reduce oxidative damage, by activation of antioxidative defense system in rats fed high fat . high cholesterol diets.
