Solitary morphea profunda is a rare form of scleroderma, characterized clinically by a solitary sclerotic plaque, and histologically by marked dermal and subcutaneous fibrosis with an inflammatory infiltrate. We describe another case of this entity presented with an ulcerative, indurated plaque on the left iliac crest, which histologically revealed a focal incidental acantholysis in the overlying epidermis and a marked eosinophilic infiltration through the dermis to the sub-cutaneous tissue.

BACKGROUND: Transforming growth factor-beta(TGF-beta) has multiple regulatory effects on cells of the immune system, and it has been suggested that differentiation of lymphoid cells is influenced by low concentra tions of this cytokine. OBJECTIVES: The aim or this study was to investigate the role of TGF-beta in regulation of T cell growth and differentiation, and to compare this effect with that of other cell signals known to be important in T cell ontogeny. METHODS: We used the CTLL-2 cell line in the presence of IL-2. Surface phenotype expression was analysed to see whether these cells could be switched to the other subtype of cells. RESULT: Treatment of CTLL-2 cells with TGF-beta resulted in dose dependent growth inhibition and morphological changes. Curing routine passage, less than 5% of cells were CD8alpha positive, whereas 38% of cells expressed CD8alpha when treated with IL-2 plus TGF-beta. However, TPA plus calcium ionophore, IFN-gamma, or TNF-alpha caused no significant changes in the proportion of CD8 cells. CONCLUSION: Our results show that this experiment can be a useful model for investigating CD8 precursor potentials in populations of CD4-CD8-(double negative) cells, and such a model may offer a way to study the molecular regulation of CD8 gene expression.

With increasing tendency of incidence and interest for the late onset schzophrenia, concerns about whether this disorder is etiologically or phenomenogically distinctive entity or not have increased also. To clarify the disease entity of the late onset schzophrenia and the role of structural brain changes in its etiology, authors tried to prove following hypothesis : Are there any evidences of structural brain changes in the late-onset schizophrenia? ; If present, are they not different from those of the early-onset schizophrenia or progressive schizophrenia? ; And are they not different from those of senile dementia? Subjects were 6 patients with the late-onset schizophrenia, 6 patients with the early-onset schizophrenia, 6 patients with progressive schizophrenia, 6 patients with Alzheimer's dementia, and 6 controls. We measured regions of interest of the magnetic resonance images by computer assisted planimetry using the AutoCad and digitizer. Our study results may suggest that the third ventricular enlargement and a reversal of normal difference between left and right temporal lobe and left-right difference in posterior lateral ventricle are common brain pathology for all type of schizophrenia including the late onset schzophrenia. And also suggest that brain structural changes of the late onset schizophrenia are related with neurodevelopmental abnormality rather than degenerative change.

We described a case of diffuse biphasic cutaneous amyloidosis, a unique form of localized cutaneous amyloidosis. A 41-year-old man has gradually developed a lichenoid papular and a grouped spotted pigmented macular eruption on the trunk and upper extremities over the past 15 years. Histopathologic examination revealed that amyloid deposits were present in the papillary dermis. It was confirmed by Congo red staining, immunohistochemistry and electron microscopy. There was no evidence of systemic amyloidosis.

PURPOSE: The purpose of this study was to identify the relation between personality traits and awareness of gender equality. METHOD: A descriptive survey design was used and 688 students in fifth and sixth grades in 3 elementary schools were selected as participants. RESULT: 1. Level of gender equality awareness among the students was 2.82. This is higher than average and was most influenced by awareness of family life, followed by awareness in education, work environment and social-cultural life. 2. Students with higher levels of extraversion-introversion had higher levels of awareness of gender equality in family life, work environment, and education. Students with higher levels of tough-mindedness showed lower levels of gender equality awareness in family life and work environment, while those with higher levels of lying showed lower levels of gender equality awareness in social-cultural life. CONCLUSION: Personality traits and awareness of gender equality were correlated to some degree. However, in order to understand the characteristics of childhood personality traits and the behaviors of our children though the mediation of the gender equality awareness as society changes, and to let them grow with understanding of gender equality, it is essential to implement various kinds of education in families, schools, and the society.
