It is generally believed that the defense against mycobacterium leprae is largely mediated through cell-mediated immunity(CMI) and several investigators have reported a defective CMI in patients with leprosy. especially the lepromatous from. This study was undertaken to ennumerate the peripheral T-cell population in leprosy patients for evaluation of one aspect of its immune status. Fiftu-two patients with leprosy(26 tuberculoid, 17 active lepromatous, 9 inactive lepromatous) entered in this study. All the patients are under regular antileprosy chemotherapy for varing periods(10 months to 14 years). Peripheral blood T0lymphocytes were enumerated by the E-rosette technique and compared with normal healthy control. The results were as follows: The mean T-cell percentage in peripheral blood was 50.6% in 17 active lepromatous leprosy patients, 62.2% in 9 inactive lepromatous leprosy patients, 67.7% in 26 tuberculoid patients and 69.5% in 17 normal healthy controls, There was marked decrease in the peripheral T-cell ratio in active lepromatous group (p<0,005) and less marked decrease in inactive lepromatous group (0.01.

OBJECTIVE : Bone mineral density is influenced by genetic, hormonal and exogenous factor that adversely affect peak mineral density include cigarette smoking, physical disability, poor calcium intake and certain medication include steroid and anticonvulsant drugs. We studied epileptic children receiving 6months above, to document change of bone mineral density by anticonvulsant drugs. METHODS: From July 1, 1996 to September 1, 1996 lumbar bone mineral density was measured by dual-energy X-ray absorptiometry in 27 children treated with anticonvulsant drugs 6months above (age ranged : 4-13 year) in Soonchunghyang University hospital. The subjects were classified into 3 groups : treated with carbamazepine alone, valproate alone and combined group. RESULTS: 1) Mean age of carbamazepine group was 10.2+/-2.42yrs(6-l4yr), duration of therapy was 22.1+/-13.9 months(6-44 months), mean value of bone mineral densities were 0.668+/-0.128g/cm2(0.548-0.927). Though it was lower than control group in 8, 9, 10, 12, 13 year, had not statistical significance. 2) Mean age of valproate group was 9.8+/-2.92yrs(6-l3yr), duration of therapy was 40.5 +/-22.2months(17-79month), mean value of bone mineral densities were 0.618+/-0.097g/cm2(0.516-0.788). Though it was lower than control group in 7, 10, 13 year, had not statistical significance. 3) Mean age of combined group was 7.9+/-3.2yrs(4-l4yr), duration of therapy was 37.5 +/-24.7months(12-88month), mean value of bone mineral densities were 0.602+/-0.109 g/cm2(0.552-0.807). Though it was lower than control group in 7, 8, 10 year, had not statistical significance. CONCLUSION: Because growing children is more sensitive than adult, in case of receiving long-term anticonvulsant therapy, it is important that early detection and prevention of abnormal bone mineralization by appropriate monitoring.

Inflammatory linear verrueous epidermal nevus (ILVEN) first mentioned by Unna in 1896 is a rare variant of epidermal nevus characterized clinically by early onset in childhood, moderate to marked pruritus and persistent clinical course and histopathologically by predominant features of a chronic dermatitis or psoriasis. We present tbe first recorded case of a typical ILVEN developed in a 20-year-old Korean male, who has had an intensely pruritic linear verrucous patch, involving the entire length of the posterior aspeet of right upper extremity, volar aspect of right thumb and nails of ind.ex and ring finger since 5 years. Microscopic examination of the skin, biopsy specimens from the lesion on the right elbow joint area and the palm showed hyperkeratosis witb focal parakeratosis, moderate to marked acanthosis and elongation of rete ridges and papilla with mild exocytosis and moderate perivascular lymphocytic infiltration. Literature were reviewed.

Two cases of epidertnoid cyst of the ovary are added to the ten reported in the literature. This rare lesion is usually an incidental finding. Its main interest is in its histogenesis, which includes metaplasia of the coelomic surface epithelium, monophyletic development of teratoma, and metaplasia of the rete ovarii. We investigated two cases of epidertnoid cyst. Histologic examination of the cysts showed a thin lining of mature keratinizing squamous epithelium rectum: unaccompanied by skin appendages or other teratomatous elements.

PURPOSE: This study examined to explore factors influencing on employment stress of university students. METHODS: The data were collected by structured questionnaires to students who agreed to be the subjects of this study. And 230 cases were finally analyzed. T-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression were conducted for data analysis using SPSS/WIN 18.0. RESULTS: Significant differences revealed in age, department of major, residental type and school year on employment stress by general characteristics. Also, employment stress showed negative correlation with self-esteem, and satisfaction in major. Self-esteem and satisfaction in major, department of major were confirmed as a factors influencing on employment stress and accounted for 36% of the variance. CONCLUSION: Further studies that discover factors influencing on employment stress of university students are needed, and also practical programs are necessary to decrease employment stress of university students.

BACKGROUND: Chlamydia pneumoniae, a new species of the obligate intracellular Chlamydia, has been recognized as a significant pathogen that causes infection of the human respiratory tract and has recently been associated with coronary atherosclerosis. Diagnosis of infections with C. pneumoniae is problematic, because the syndrome usually presents few distinguishing features and culture of the organism is far more difficult than other Chlamydia species. To further improve the cell culture isolation and passage of C. pneumoniae organisms. we have studied several chemical and physical factors that might affect their viability and growth. METHODS: C. pneumoniae strain (TW-183) was obtained from the Centers for Disease Control, Atlanta. Ga. First we compared McCoy HeLa-229, and HEp-2 cells in the search for a more efficient and practical cell culture system. The growth rate of C. pneumoniae was assessed by the effects of diethylaminoethyl-dextrin, by the adequate centrifugation force and time, by the growth promoting effect of cycloheximide, and by the optimal incubation time. All of the results were evaluated by the indirect immunofluorescent stain using the genus-specific monoclonal antibody(HYMo 1-1) to Chlamydia. RESULTS: The HEp-2 cell was the most efficient for culturing C. pneumoniae and the inclusion bodies in monolayer were increased with DEAE-dextran pretreatment at 30microgram/ml. Also application of a centrifugal force of 1.500 xg for at least 15 minute during inoculation enhanced the growth of C. pneumoniae. The best concentration of cycloheximide in the culture medium for host cell cytostasis was 1microgram/ml. The yields of organisms were greater when the cultures were harvested at 48 hours. CONCLUSIONS: We suggest that this system may make it more practical for laboratories to culture for C. pneumoniae.

The formation of spontaneous rosettes between human lymphocytes and sheep erythro ytes under suitable conditions is a constant feature of T-lymphocytes. Recently. It has been demonstrated in the mouse, rat, guinea pig and in man that a certain proportion of peripheral blood lymphocytes has the property to bind autolognus erythrocytes in vitro. These lymphocytes are called auiologous rosette forming cells(ARFC). Although there are several reports on human ARFC. the results are not in accordance. The present study was undertaken to demonstrate the autologous rosette forming property of human peripheral blood lymphocytes, and to enumerate the percentage of ARFC in different sex and age guoups. Fifty healthy persons entered this study between Martch and September. 1980. at the Department of Dermatolgy, Seoul National Universty Hospital. The method of quantitation of AREC was s sight modification of that of Lambermont et al(1977). The results were as follows.

Nickel sensitivity is the most common cause of allergic metal dermatitides,, particularly in women. Women are uaually sensitized. by the objects wom close to the skin ('e.g. earring, necklace fasther, watch, suspenders, brassiere clips, etc.), and men are by occupational exposures (e.g. plating or printing industries, tools, etc.). Nickel dermatitis is frequently developed on the sites where seems to have been directly contact witb nickel substance, but secondary eruptions may develop on the areas where seems to have not been directly exposed to nickel, so that nickel dermatitie is sometimea misdiagnosed as atopic dermatitis, nummular eczema, stasis dermatitis, or other dermatitides. The authora prcsent two cases of nickel dermatitis confirmed by patch test with 2. 5% nickel sulfafte; first case-a 22 years old female who has erythemat,ous maculopapular patches on her ears, around neck, left wriat, elbows, and abdomen; second case tkat was previously misdiagnosed as mummular eczema-a 18 years old female who has large oozing and crusted patches on both lateral aspects of her right thigh and back, The authors reviewed the incidence of nickel sensitivity during past years in korea and the clinical aspect of distribution of nickel dermatitis.
