In order to assess the epidermal glycogen in the epidermal hyperplastic disease, PAS(Periodic Acid Schiff) stain with or without diastase is used. Epidermal PAS positive reaction is significantly increased in psoriasis (90. 0%), verruca vulgaris (100%) and lichen simplex chronicus (100%) than control group (12, 5%) Epidermal PAS positive reaction is relatively increased in prurigo nodularis(66. 7 %) and chronic contact dermatitis (75%) Strong PAS positive reaction is noticed in 3 of 5 cases (60%) with verruca vulgaris, but none of 22 cases with psoriasis. It is suggested that epidermal glycogen epidermal hyperplasia and that the more glycogen accumulated. than control group (12. 5%) in 3 of 5 cases (60%) with verruca vulaccumulation is accompanied with the hyperplastic the epidermis is, the more glycogen accumulated.

Lipoprotein(a)[Lp(a)] is a LDL-like particle with a glycoprotein called apo(a) attached to its apoB through disulfide bond. Many case-control studies support the opinion that plasma Lp(a) levels were associated with coronary artery disease. This study was conducted to assess the relationship between plasma Lp(a) level and coronary artery disease in Korean population. Serum levels of Lp(a), in addition to other lipids and known clinical risk factors for coronary artery disease were determined in 92 subjects undergoing coronary angiography. Among them 30 patients had no obstruction in the coronary artery(cath-control group), while the others revealed the presence of coronary artery stenosis more than 50%(CAD group). The Lp(a) levels of the CAD group were significantly higher the those of cath-control group(31.8+/-25.0mg/dl vs 14.6+/-11.9mg/dl, p<0.005). Other lipids except triglycerides(166.9+/-70.5mg/dl vs 116.2+/-56.1mg/dl, p<0.005) were not significantly different between two groups. The patients with significant coronary artery disease of two or more vessels were found to have higher Lp(a) levels than those of one vessel disease. Lp(a) levels had no relations with other lipids, diabetes, smoking, hypertension and age. Stepwise discriminant analysis revealed that Lp(a) was the best discriminator among risk factors for coronary artery disease. These results suggested that Lp(a) level was a significant independent risk factor for coronary artery disease.

Spindle cell hemangioendothelioma was first described in 1986 by Weiss and Enzinger as a low grade angiosarcoma resr mbling a cavernous hemangioma and kaposis sarcoma. Recently, it is suggested to be non neoplastic lesion or reactive process arising from pre-existing vascular mal- formation. We report a case of spindle cell hemangioendothelioma in a 9-month-old boy. He had multiple, variable sized, colorful, cutaneous or subcutaneous nodules on the forearm and hand. The tumor first appeared on the forearm as erythematous patches at birth and grew rapidly with- in 3 months. Histopatholgical findings showed that the lesion was composed of thin walled cavernous spaces mixed with spindle cells and occasional epithelioid endothelial cells containing intracytoplasmic vacuole. Most af the endothelial cells lining the cavernous spaces and intracytoplasmic lumina, were positive for factor VIII associated antigen. But the spindle cells were negative. Atypical vascular structures resembling arteriovenous shunts were noted around the tumor suggesting a reactive proliferation due to disturbance of local blood flow. Several turnors were excised. No recurrence has been recognized in the one year- follow-up period.

BACKGROUND: Evaluating the segmental wall motion of left ventricle is important in patients with myocardial infarction for choosing therapeutic modality and predicting prognosis. Radionuclide Multigated Angiography(MUGA) is a reliable noninvasive method for the evaluation of left ventricular performance. Methods : MUGA scan(LV ejection fraction, phase image histogram, regional wall motion) was performed and analyzed in 45 patients with myocardial infarction(31 : acute MI, 14: old MI) and 13 normal controls. RESULTS: 1) The LVEF of acute and old MI group was significantly reduced and the SDph of acute and old MI group was significantly increased as compared with that of control group(p<0.05). 2) In acute MI group, the LVEF of group without, IV Urokinase was more reduced than that of group with IV Urokinase and the SDph of group without IV Urokinase was more increased than that of group with IV Urokinase(p<0.05). As a result of wall motion scoring, the linear correlation exists between SDPh and sum of wall motion scoring(r=0.62, p<0.01). 3) In MI group, the LVEF of anterior wall MI was more reduced than that of inferior wall MI and the SDPh of anterior wall MI was more increased than that of inferior wall MI(p<0.05). 4) In acute anterior wall MI, the reverse correlation exists between LVEF and SDPh and the linear correlation exists between sum of wall motion scoring and SDPh(r=-0.73, 0.72, p<0.01). But there are no statistical significances of correlation between them in acute inferior MI(r=-0.44, 0.42, p>0.05), in old anterior MI(r=-0.65, 0.47, p>0.05) and in old inferior MI(r=-0.47, 0.46, P>0.05). CONCLUSION: These results suggest that Phase angle(SDPh) is thought to be valuable index to evaluate left ventricular function with application of other indeces in Myocardial infarction. Left ventricular function measured by SDph in acute or anterior MI is lower than old or inferior MI.

BACKGROUND: Portable devices for measuring peak expiratory flow(PEF) are now of proved value in the diagnosis and management of asthma and many lightweight PEF meters have become available. However, it is necessary to determine whether peak expiratory flow rate(PEFR) measurements measured with peak flowmeters is accurate and reproducible for clinical application. The aim of the present study is to define accuracy, agreement, and precision of mini-Wright peak flow meter(MPFM) against standard pneumotachygraph. METHODS: The lung function tests by standard pneumotachygraph and PEFR measurement by MPFM were performed in a random order for 2 hours in 22 normal and 17 asthmatic subjects and also were performed for 3 successive days in 22 normals. RESULTS: The PEFR measured with MPFM was significantly related to the PEFR and FEV1 measured with standard pneumotachygraph in normal and asthmatics(for PEFR, r=0.92 p<0.001; for FEV1, r=0.78 ; p<0.001). The accuracy of MPFM was within 10%(limits of accuracy recommeded by NAEP) in all the subjects or 22 normal, mean difference from standard pneumotachygraph being I 6.5L/min(percentage of difference being 2.90%) or 1 0.6L/min(percentage of difference being 1.75%), respectively. According to the method proposed by Bland and Altman, the 95% limits of the distribution of differences between MPFM and standard pneumotachygraph after correction of PEFR using our regression equation were +38.2 and -71.5L/min in all the subjects or -20.49~ + 9.49L/min in 22 normal and was similar to the intraindividual agreements for 3 successive days in normal. There was no statistically significant difference of PEFR measured with MPFM and standard pneumotachygraph among three days(p>0.05) and the coefficient of variation(2.4 1.2%) of PEFR measured with MPFM was significantly lower than that( 5.2 3.5%) with standard pneurnotachygraph in normal (p<0.05). CONCLUSION: This results suggest that the MPFM was as accurate and reproducible as standard pneumotachygraph for monitoring of PEFR in the asthmatic subjects.
