Serum zinc is an essential element in men and animals. Recently on the dermatologic fields, the serum and the skin levels and the roles of zinc have been studied especially in acne vulgaris, but the results were controversial. So to confirm the previous reports and for evaluation of the relationship between the various aspects of acne vulgaris and the serum levels of zinc, the serum levels of zinc were measured by atomic absorption spectrophotometer in 13 healthy controls and 46 patients with acne vulgaris. In the healthy controls, their mean values of zinc were 0.843+0.251 ppm in total, 0.920+0.219 ppm, in females and 0.777+0.260 ppm in males. There was no statistical difference attributable to sex. In the 46 patients with acne vulgaris, their mean value of zinc was 0.741+0.195 ppm. There was no significant difference in the mean serum zinc level compared with the controls. In the males with acne, the mean va1ue of zinc was 0.727+0.166 ppm, and 0.748+0.208 ppm in females with acne. There was no significant statistical difference between males and females with acne. And females, but not males, with acne had significantly lower serum zinc levelss than controls of the corresponding sex. (p<0.1) By clinical severity, classifying the 46 patients with acne vulgaris into three groups: mild type (only comedones), moderate type (comedones with pa.pules) and severe type (includes pustules, comedones, and papules, etc.), the serum zinc levels of each group were 0.774+0.185 ppm, 0.7880. 200 ppm and 0.666+0.176 ppm. The significant statistical difference was found only in the severe type of acne compared with the healthy controls (p<0.05). Also classifying the patients into three groups (acute, moderate and chronic types of acne) by duration of acne, the serum values of zinc were 0.738+0.158 ppm, 0.692+0.283 ppm and 0.769+0.241 ppm, respectively. Only in the moderate type of acne, the mean serum level of zinc was significantly reduced compared with the control group (p<0.1)

Incontinentia pigmenti is an uncommon genodermatosis. It affects female infants predominantly, described first by Bardach in l925, with the diagnosis of systematized nevus and Bloch in 1926, and Sulzberger in 1928 rnore compIetely. Skin lesions are characterized by 3 stages such as vesicobullous, verucous and finally pigmentary lesions and leave brownish pigmentation on the extremities and trunk. Hesides skin lesions some ectodermaI and mesodermal organs are affected and show developmental abnormalities. We experienced a case of incontinentia pigmenti in a 45-day-old female infant and present it with the review of literature. She showed extensive vesicobullopustular eruption with linear and reticular pigmentation on the extremities and trunk. Clinical and histopathologic findings of these lesions are compatible with Bloch-Sulzberger type of incontinentia pigmenti.

A case of toxic epidermal necrolysis (TEN) was presented in 46 year-old male patient. The characteristic skin lesions of TEN were developed after some medictions and tetanus anti-toxin (TAT) injection due to trauma. Probably, the cause of the disease was drugs, TAT injection or trauma inself. On the pathologic findings, lower epidermis and dermo-epidermal cleavage were noticed. He was treated with massive antibiotics and steroid. About 7 days after therapy, much improvement achived. However foul odorous yellowish discharge was noticed since 20 days of hospitalization. Wide debridement of necrotic tissue was carried without improvement. Patient expired on 48th hospital day due to sepsis and impending hepatic coma.

Authors performed film mammography in 2167 patients with breast complaints who had visited to Yong DongSeverance hospital, Yonsei University from October 1, 1983 to September 30, 1985. Authors analysed 62 cases offilm mammographic findings and 35 cases of ultra mammographic findings among confirmed 62 fibroadenomas and alsoauthors analysed histopathologic cell type and ultra mammographic findings of confirmed fibroadenomas. The resultsfollowed: 1. The most prevalent age group was 3rd and 4th decade(74%). 2. The common dense breast pattern by Wolfeclassification were P2 and DY patterns(80%) in film mammograhy. 3. The most common size of fibroadenomas was1.1-3.0cm (71%) in long diameter. 4. Film mammographic findings of fibroadenoma generally showed single mass in 54lesions(87%), well defined margin of mass in 45 lesions (58%) and halo sign in 62 lesions(80%). Well definedmargin of mass is prominant in ductal cell dominant fibroadenoma(71%) , however lobulation of margin is commonlyseen instromal component dominant fibroadenoma(15%) and spiculated margins of mass can be seen in mixedfibroadenoma(6%) and stromal component dominant fibroadenoma(3%). Halo sing of fibroadenoma was commonly seen inductal cell dominant fibroadenoma(86%) and stomal component dominant fibroadenoma(85%). 5. Ultra mammographicfindings of fibroadenoma showed oval shaped mass in 26 lesions(15%) with smooth margin of mass in 43 lesions(84%)and showed mostly intermediate internal echo in 48 lesions(94%). Relationship between histopathologic cell typeand ultra mammographic findings were. Round shaped mass(67%), lateral shadowing (74%) was common in mixed type offibroadenoma, lobulated margin of mass(45%), intermediate(94%) with unifrorm(78%) internal echo was common instromal dominant type of fibroadenoma and smooth contour (100%), uniform internal echo fo mass(83%) was common inductal cell dominant type of fibroadenoma. Most ultra mammographic L/T Iratio of fibroadenoma was 0.5-1.0 in 37lesions(73%) 6. The diagnostic accuracy of film mammogahy in fibroadenoma was 92%, however combined imagingmodalities raised the diagnostic accuracy into 95%.

We investigated the occurrence of color vision loss in 70 organic solvent mixtures exposed workers and in 47 controls. Color Vision was assessed with a color arrangement test designed to identify the defective color sense, the Han Double 15-Hue Test. The results of the test were no significant difference between exposed workers and controls in the proportion of subjects who committed one or two errors. Quantitative analysis, using color confusion index(CCI), showed no signifiant difference between exposed workers and controls. A significant linear correlation was present between age and CCI in both exposed workers(CCi=0.0056age + 0.94; r=0.23; p<0.05) and controls(CCI=0.0066age + 0.86; r=0.33; p<0.05). Qualitative analysis of the patterns on the hue circle showed that the prevalence of acquired dyschromatopsia was 21% in both and no significant difference. Multiple regression analyses showed that age was significantly related to color vision loss. These results did not provide evidence of a relationship between organic solvents exposure and incidence of color vision loss. In field studies for monitor the people at risk of the acquired color vision loss involving low-dose organic solvents exposed workers, both quantitative and qualitative information should be considered.

Antianginal and untoward effects of fenalcomine hydrochloride were studied in 24 cases of angina pectoris. Following discontinuation of all medications for 2 weeks except for liberal use of sublingual nitroglycerin for the relief of anginal attack, fenalcomine, 150mg a day in 3 divided doses, was given for 8 to 16 weeks. In 20 cases, routine blood counts including platelets, serum electrolytes and cholesterol as well as blood sugar level were checked before and at the completion of the medication. hepatic and renal functions were also studied. The effect of fenalcomine on severity, frequency and duration of anginal attack was excellent to good in 17 cases(70.9%), and was fair in 5 cases(20.8%). In the remaining 2 cases(8.3%), who responded poorly had angina pectoris for more than 3 years. It appeared that fenalcomine was similarly effective in those with or without associated hypertension or diabetes mellitus, or history of previous myocardial infarction. The comparison of the results of post-treatment laboratory tests with pre-treatment data revealed no significant changes. Furthermore, no untoward clinical reactions attributable to the drug was noted in all cases. These facts suggest that fenalcomine is a reliable and well tolerated antianginal agent which can be used singly or in combination with other agents.

BACKGROUND: Intracellular ionized calcium plays a central role in the transduction of external stimuli as a critical second messenger. The spectral properties of fluo-3 allows the analysis of intracellular ionized calcium level by flow cytometers. The aim of this study is to assess the performance of flow cytometer for measuring intracellular ionized calcium level using fluo-3 and to define the reference interval of intracellular ionized calcium level of lymphocytes from healthy people, and to find out the clinical implications according to various disorders. METHODS: For the analytical performance of flow cytometer on determining the concentration of intracellular ionized calcium, precision study, lowest limit of detection, analytical range, and the loading stability of fluo-3 were per foamed. Fifty-four cases of healthy people, 52 cases of renal transplant patients, and 20 cases of diabetes mellitus patients were included in this study. RESULTS: Loading effect of fluo-3 at room temperature was stable upto 5 hours. Lowest limit of detection of ionized calcium concentration was 4.34 nM at in-situ calibration procedure. Within-run and among-day intraindividual CVs of in-situ calibration procedure were 6.67% and 13.99% respectively, and of optical calibration procedure were 13.86% and 16.12% respectively. The reference interval of cytosolic free calcium level for healthy people ranged 73.54 - 155.09 nM without sexual differences. The level of intracellular ionized calcium was lowered by 36.9% on renal transplant group in comparison with healthy control group. But, level of cytosolic free calcium was Increased upto 276.0% on acute rejection group and 159.1% on diabetes mellitus group compared to control group. CONCLUSIONS: These results reveal that in-situ calibration method for intra cellular ionized calcium using flow cytometry with flue-3 can be regarded as an accurate and standardized method. Quantitation of intracellular ionized calcium level might be used as the monitoring test for early detection of acute rejection after renal transplantation.
