1.Four Cases of Herpes - Associated Erythema Multiforme.
Korean Journal of Dermatology 1987;25(6):773-776
We describe four patients with herpes-associated erythema multiforme, who had clinical and histopathological features consistent with the so-called erythema multiforme minor. The appearance of lesions of herpes simplex were followed with intervals between 6 and 10 days by the recurrent developments of erythema multiforme several times in a year in each patient. Sinee herpes simplex virus infection is considered one of the major factors provocating erythema multiforme one may have to pay more attention to patient's history to define the nature of erythema multiforme.

OBJECTIVE: The kinetic indices of apoptosis and cell proliferation m a histopathologic spectrum of the cervical neoplasia were evaluated to clarify the correlation between cervical neoplasm and apoplasis. Specific lesioas included cervical intraepithelial neoplasia(CIN), catcinoma in situ(CIS), and invasive carcinama. METHODS: Archival samples from normal cervical epithelium(n=7), low-grade squamous intraepithelial lesions(LGSIL, n=17), high-grade squamous intraepithelial lesions(HGSIL, n=17), invasive squamaus carcinoma(n=7) were evaluated for apoptosis and cell proliferation. Apoptotic cells were identified with terminal deoxynucleotidyl transferase-labeling of the 3'-OH end of DNA nucleosomes, and then apoptotic index(A.I sum of apoptotic bodies/ 1000 tumor cells) and total cell count(* 400 magnification) were calculated. RESULTS: In normal squamous epitheliam, Apoptotic bodies were mainly localized in ial layers, for low-grade squamous intraepithelial lesions(HGSIL) in superficial and intermediated layers, for high-pade squamous intraepithelial lesions(HGSIL) in intermediated and parabasal layers, for invasive carcinoma in full thic of squamous epithelium. Apototic indces(AI) in invasive carcinoma(mean: 6.21) were significantly higher than indices for high-grade squamous intraepithelial lesions(HGSIL, mean: 0.98) and high-grade squamous intraepithelial lesions(HGSIL, mean: 0.98) were significantly higher than indices for low-grade squamous intraepithelial lesions(LGSIL, mean: 0.12)(p<0.01), the total cell counts increased significantly as the specimens progressed toward invasive disease. (p<0.01) CONCLUSION: Apoptosis in cervical neoplasia appears to be closely related to poliferation and progression of the cervical squamous epithelial cell. This phenotype may allow identification of premalignant lesions with the potential to transform to cervical cancer.

4.Effects of Selective Serotonin Reuptake Inhibitors on the Retention of Passive Avoidance Learning after Chronic Mild Stress in Rats.
Journal of the Korean Society of Biological Psychiatry 1997;4(2):237-245
The study was designed to evaluate the significant roles of SSRI in rat of depression model. Chronic exposure to mild unpredictable stress has been found to depress the consumption of sweet 1% sucrose solutions in the Sprague-Dawley rats. We applied the variety of 11 types of stress regimens and identified depressive behavious(developed by Willner) in 70 Sprague-Dawley rats. Rats in experiments were stratified into 6 groups, i.e.; 3 kinds of SSRI(paroxetine, fluoxetine, sertraline), clomipramine, choline and saline control. Memory function was evaluated by passive avoidance learning and retention test. The authors determined how long memory retention would remain improved with 24 hour, 1 week, 2 weeks, 3 weeks, and 4 weeks at training-testing interval in depressive states of the Sprague-Dowley rats. The results were as follows; 1) There were to significant differences between the 6 groups at the 24 hour training-testing interval. 2) The paroxetine treated group showed significant differences from the control group at the 1 week and 2 weeks training-testing interval. 3) The paroxetine and the fluoxetine treated groups showed significant differences from the control group at 3 week training-testing interval. 4) The paroxetine and the choline treated groups showed significant differences from the control group 4 week training-testing interval. In summary, paroxetine had on effect on long term memory processing from 1st week to 4th week. Also, fluoxetine(or 3rd week) and choline(at 4th week) had effect on long term memory processing. Sertraline, clomipramine were ineffective on memory processing during 4 weeks observation. Possible explanations why paroxetine had early effect on memory processing than the other selective serotonin reuptake inhibitors are rapid bioavailability, which is the characteristics of pharmacokinetics of paroxetine. In clinical situation, author carefully suggest that SSRI would be beneficial to improve the memory function caused by depressive neurochemical changes.

In Systemic lupus erythematosus several correlations with anti-Ro antibodies have been noted. They are the increased incidence of photos nsitive skin disease, rheumatoid factor positivity, Sjogren's syndrorme, and a greatly increased incidence of the DR 3 hapIotype. In this study we examined the prevalence of anti-Ro anibodies(not concerned for anti-La, Sm, RNP) by double immunodiffusion method among thirty two Korean patients with systemic lupus erythematosus who had positive results on routine fluorescent antinuclear antibody test. We also have seen skin manifestations on these patients, and examined if there is any difference of the incidence for each skin sign between anti-Ro positive and negative subgroups. From the data obtained, the proportion of anti-Ro positives among these patients with systemic lupus erythematosus was 53% Regarding to the difference of the incidence of cutaneous rnanifestations between the two subgroups, the photosensitivity reaction was recongnized as a uniqu symptorn rnore prevalent (p<0. 05) in anti-Ro positive subgroup with the frequency of 65%.

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.

Anti-T cell monoclonal antibodies(OKT series. OKT4a, OKTSA, OKT)1) immunoperoxidase technique study for the presence of T cells in cutaneous lesions from four patients with erythema multiforme showed that most dermal and epidermal lymphoid cells were reactive with monoclonal antibodies to anti-pan T cell (l3KT11) in this semiquantitative assay. In the dermis most of the perivascular lirmphoid infiltrates were reactive with anti-helper/inducer T cell antibody, but in the epidermis and in the derrnopidermal interface the predominant cells were identified as suppressor/cytotoxic T cells. The histologic and immunopathologic changes in erythema multiforme appear to be due in part to cellular immune rnechanisms with the lyrnphocyte as the predominant effector cell. But complex interplays with other humoral immune mechanisms might be in work for the development of erythema multiforme.

To investigate the changing patterns of microfilament and microtubule arrangement and influence of myocardial cells and colchicines to microfilament and microtubule formation in cardiac endothelial cells the authors carried out indirect immunofluorescence stain for actin and tubulin with supernatant monoclonal antibodies. Secondary antibodies were IgG FITC conjugate. The results were summarized as follows. Fiberform reactions were stronger in the cells with many processes and spread cytoplasm and they became weaker after the endothelial cells formed monolayer. In the endothelial cells cocultured with myocardial cells the fiberform of the microtubule became less visible compared to control group but fiberform of the microtubule maintained strong intensity as endothelial cells formed monolayer. In the group treated with colchicines, there were no visible differences in microfilaments compared to control group but fiberform of microtubule revealed weaker intensity after colchicines treatment. The intensity of microtubule fiberform returned to control level after 2 days.

Korean Journal of Dermatology 1992;30(5):577-584
The clinical spectruni of epidermolysis bullosa acquisita(EBA) is much broader than originally thought. Although the full extent of the clinical presenation is still being defined, it is now known that EBA include the followings: a non-inflammatory mechanobullous condition equating wit,h classical EBA; an inflammatory vesiculosullous eruption mimicking bullous pernphigoid; and a mucosal-centered disease with sarring similar to cicatricial pemphigoid. Among the nine cases of EBA, aged between 34 to 70 year-old, seen in recent years, three patients had mechanobullous lesions with skin fragilities and scarrings; three patients had inflammatory bullous eruptions, and three other patient had combined features of mechanobullous/inflammatory bullous lesions. Mucous membrane lesions were recognized in sex cases, and the rnos! frequent site of involvement was the oral mucosae. According to observations of these patients episodes of inflammatory bullous eruptions appeared to be present in seven cases and have been considered as early sympoms of the disease. It has been noted, however, that in two cases lesions develop d as an non-inflammatory mechanobullous from thonset. Based on the ability of EBA to mimick bullous pemphigoid or cicatricial pernphogoid and the fact that such cases have perhaps been missed, we feel EBA is more common than past literature has suggested.
