This study was done on 171 volunteers in order to investigate the present status of cutaneous normal flora of Candida species and the distribution of Candida species on the normal human skin in dermatologic clinic of Korea University Hospital from January, ]984 to December, 1984. Among the 171 volunteers, 115 strains of Candida species were identified by culture on the Sabouraud's dextrose agar media, germ tube test, sugar assimilation test, sugar fermentaion test and culture on corn meal with Tween 80 media, The results were summarized as follows: 1. The incidence of cutaneous normal flora of Candida species was 13, 5,5 (115 species among 855 sites) 2. Candida species were distributed in oral cavity(45 species), 4th interdigital toe web(39 species), groin(12 species), axilla(11 species) and 4th interdigital finger web(8 species) in order of frequency. 3, Of ll5 species, 45 species were cultured in summer, 27 species in autumn, 18 species in winter and 14 species in spring. 4 Of 115 Candida species, C. albicans(88 species), C. parapsilosis(12 species), C, tropicalis(8 species), C. guilliermondii(3 species) and C. stellatoidea(2 species) were identified. Two species could not be identified.

BACKGROUND: We reviewed retrospectively the clinical features and contrast material-enhanced computed tomography(CT) after blunt abdominal trauma demonstrated a characteristic hypoperfusion complex. Our purpose were to evaluate the hypothesis that children with this 'hypoperfusion complex' CT finding were associated with a tenuous hemodynamic state, severe injury and a poor outcome. METHODS: Between January 1996 and December 1999, 39 consecutive children who sustained blunt trauma and were suspected clinically of having intraabdominal injury underwent CT. Demographic data, blood pressure, indication for CT, pediatric trauma score(PTS) and Glasgow coma score(GCS) were recorded at the time of the initial examination. RESULTS: Three of the 39 children(8%) demonstrated a characteristic finding at CT which was described as the hypoperfusion complex. The 'hypoperfusion complex' was present in the 3 of the 39 traumatized children(8%), but was the main radiographic finding in the 3 of the 14 children with a severe pediatric trauma score(PTS<8) and in the 3 of the 6 children with a Glasgow coma score(GCS<8) who were examined with CT. CONCLUSION: The CT finding in all children with the hypoperfusion complex by definition included marked, diffuse dilatation of the intestine with fluid; abnormally intense contrast enhancement of the bowel wall, mesentery, kidney and/or pancreas; decreased caliber of the abdominal aorta and inferior vena cava(IVC); and moderate to large peritoneal fluid collection. This 'hypoperfusion complex' is a relatively rarely observed in injured children but appears to be associated with severe injury and a poor outcome. The pediatric trauma score provides a useful profile of injury severity in children. Prompt diagnosis of hypovolemic shock is important so that supportive therapy can be instituted to prevent further metabolic abnormalities and their potential cardiotoxic effects. In summary, the intense multiorgan enhancement pattern seen in the hypoperfusion complex indicates tenuous hemodynamic stability and is associated with a poor outcome.

OBJECTIVE: Several water channels (aquapoins; AQP) that belong to the MIP (major intrinsic protein) family have identified. In the selected tissues including red blood cells or renal tubules, water movements are abundant and/or physiologically important. Unexpectedly, a high water permeability of human and ram sperm has been reported. Recent studies showed that AQP7 and AQP8 are present in testes so that the high water permeability of human sperm suggested to be mediated by AQPs. METHOD: To identify the identity of aquaporins expressed in testes, RT-PCR was performed using degenerative primers, which were designed to correspond to highly conserved sequences surrounding the Asn-Pro-Ala (NPA) motifs in the aquaporins. New expressed AQP series were reconfirmed by immunohistochemical study using rabbit polyclonal antibodies. RESULTS: DNA sequencing of PCR products revealed that AQP2 and AQP3 mRNA as well as AQP7 and AQP8 are expressed in human and rat testes, AQP2 are expressed in spermatozoa, interstitial cells and myofibroblasts and AQP3 are expressed in myofibroblasts of semineferous tubules on immunocytochemical stain. CONCLUSION: These results indicate that multiple aquaporins are expressed in testes, and that they may have important roles in the spermatogenesis and the germ cell function of testis.

A case of cutaneous sarcoidosis in the 66 year-old Korean female patient is presented. She shows typical skin manifestations of plaque type in the absence of other common objective evidence of systemic involvement. Diagnosis was confirmed by charcteristic histological findings and positive Kveim test with the support of other compatible clinical and biochemical findings. She had been followed up for 3 years since the first visiting. Recently chest X-ray, slit lamp examination and skin biopsies were taken again, but failed to reveal any significant interval changes.

OBJECTIVES: To investigate the relationship between job stress and the variables associated with the organizational effectiveness of dental technicians. METHODS: The job stresses were divided into the following six components; somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, and hostility. The organi-zational effectiveness variables in this study included job satisfaction, occupational commitment, organizational commitment and intent to leave. The sample used in this study consisted of 248 dental technicians working in hospitals and dental laboratories. The data were collected with self-administered questionnaires between March 16 and April 29 in 2002, and the results analyzed with ANOVA and multiple regression analysis. RESULTS: Firstly, job stress of dental technicians was found to be significantly different in relation to the number of workers at the workplace and the working hours. The level of job stress was the highest when the number of workers were more than 10, or when the daily working hours were over 12. Secondly, of the six variables of job stress, five variables of somatization, interpersonal sensitivity, depression, anxiety, and hostility were found to have significant negative correlations with job satisfaction. Thirdly, all six job stress variables were found to have significant negative correlations with the occupational and organizational commitments of the dental technicians. Finally, depression was the only job stress variable found to have a significant effect on the dental technicians' intent to leave. CONCLUSIONS: The results of this study indicate that personal and organizational efforts are very important to improve the organizational effectiveness in reducing work related stress. Organizational support, especially for managing the depression of dental technicians is recommended.

Convcntional Kaposi's sarcorna is distinguished frorn AIDS-associated Kaposi's sarcorna.. The authors report a case of 65 year-old male who presented with a nodular type of conventional Kaposi's sarcoma. The result of the serum antibody test against HTLV-3 in this patient was negative. Trial with b-interferon administered systemically and by local injection showed favorable results. Following 4 weeks of treatment, the tumor masses had markedly decreased in size. The authors suggest that b-interferon treatment for this patient was effectivc.
