BACKGROUND: CD30 is a member of TNF receptor family and expressed on lymphocytes and other hematopoietic cells following activation as well as Hodgkin and Reed- Sternberg cells in Hodgkin's lymphoma. In this study, CD30-mediated regulation of cell adhesion molecule expression on normal activated mouse T cells was investigated. METHODS: Mouse T cells were activated with anti-CD3 antibody for induction of CD30, which was cross-linked by immobilized anti-CD30 antibody. RESULTS: High level of CD30 expression on T cells was observed on day 5, but only little on day 3 even under culture condition resulting in an identical T cell proliferation, indicating that CD30 expression requires a prolonged stimulation up to 5 days. Cross-linking of CD30 alone altered neither proliferation nor apoptosis of normal activated T cells. Instead, CD30 appeared to promote cell adherence to culture substrate, and considerably upregulated ICAM-1 and, to a lesser extent, ICAM-2 expression on activated T cells, whereas CD2 and CD18 (LFA-1) expression was not affected. None of cytokines known as main regulators of ICAM-1 expression on tissue cells (IL 4, IFNgamma and TNFalpha) enhanced ICAM-1 expression in the absence of CD30 signals. On the other hand, addition of NF-kappaB inhibitor, PDTC (0.1 mM) completely abrogated the CD30-mediated upregulation of ICAM-1 expression, but not CD2 and ICAM-2 expression. CONCLUSION: This results support that CD30 upregulates ICAM-1 expression of T cell and such regulation is not mediated by higher cytokine production but NF-kappaB activation. Therefore, CD30 may play important roles in T-T or T-B cell interaction through regulation of ICAM-1, and -2 expression.

Large numbers of reports have shown that thermal injury (TI) causes a wide spectrum of defects in immune response that lead to a high susceptibility to various opportunistic infections. However, it is still a matter of debate whether TI induces Th2 polarization or global impairment in Th1/Th2 response. In this study, TI in a mouse model was induced by exposing shaved dorsal skin to boiling water and cytokine production was analyzed. At day 2 of injury, whole spleen cells and T cells were collected and then stimulated with an anti-CD3 antibody. The levels of cytokine secretion were determined by cytokine ELISA. Production of IFNgamma and IL 4 by whole spleen cells from injured mice were concurrently decreased when compared to those from sham-injured controls. Proportional changes in T, B, and T-subset cells were not accompanied. Using purified T cells devoid of accessory cells (AC), it was shown that those defects resulted primarily from lowered T cell potentials. By using mixed cultures of sham T and TI-AC and vice versa, it was revealed that AC also acted as inhibitor cells in IFNgamma and IL 4 production in less extent. Blockade of glucocorticoid signals rendered the T cells partially resistant to TI-induced inhibition in IFNgamma and but not IL 4 production. These results clearly demonstrate that TI induces overall suppression in Th1 and Th2 response through T cell dysfunction together with the inhibition of AC activity, and that reduction in only IFNgamma but not IL 4, production may be caused, in part, by corticosteroid hormone that is secreted prominently during trauma.

This report presents a unique case of checkrein deformities in both halluces following isolated intramuscular sarcoidosis, a rare occurrence given the infrequent musculoskeletal involvement in sarcoidosis. Typically resulting from flexor hallucis longus tendon entrapment by scar tissue post-trauma, the checkrein deformity reported in this paper presented with unusual metatarsophalangeal joint flexion and interphalangeal joint extension during ankle dorsiflexion. A 49-year-old woman with a history of intramuscular sarcoidosis presented with a great toe deformity and discomfort while wearing shoes, leading to a diagnosis of dynamic deformity, possibly attributed to tendon tethering by sarcoidosis. Surgical treatments, including abductor hallucis muscle intratendinous tenotomy, flexor hallucis longus Zplasty lengthening, Weil osteotomy, and Kirschner wire fixation, significantly improved the functional scores and patient discomfort.This report underscores the importance of recognizing dynamic deformities and the potential for rare diseases, such as sarcoidosis, to cause such conditions, highlighting the need for careful diagnosis and tailored surgical intervention for atypical checkrein deformities.

OBJECTIVES: The purpose of this study was to develop new meal planning tools for a nutritionally balanced diet. METHODS: Based on the food exchange list for diabetes, we adjusted the food group classification system to reflect the suggested nutritional factors for chronic disease prevention and health promotion. We developed a nutritionally balanced dietary profile for adults and compared it with the dietary reference intakes for Koreans (KDRIs) and the food pattern recommended by the Korean Diabetes Association. RESULTS: The newly developed menu planning tools are the LOHAS food exchange table and the LOHAS food pattern. Our recommended daily 1,800 kcal dietary composition for adults is as follows: The carbohydrate food group consists of 4 ‘whole grains’, 3 ‘refined grains’, 2 ‘sugars’, 9 ‘vegetables’, 3 ‘starchy vegetables’, 2 ‘fruits’ and 1 ‘high sugar fruits’. The protein food group includes 3 ‘plant protein foods’, 3 ‘animal protein foods (low-fat)’, and 1 ‘animal protein foods (high-fat)’. The fat food group consists of 2 ‘oils and nuts’ and 1 ‘solid fats’. The total number of calories is estimated at 1,840 kcal and the energy ratio is 62% carbohydrate, 18% protein, 20% fat, 6.8% saturated fat and 13.2% sugars. Using the LOHAS food exchange table, it is possible to estimate values of saturated fat, unsaturated fat, dietary fiber, and sugars besides carbohydrate, protein and fat. It is also possible to compose a dietary design considering carbohydrate, sugars, saturated fat and dietary fiber. The LOHAS food pattern provides benefits for the management of both institutional food services and individual meals, as it can help reduce the levels of saturated fat and sugar intake and help develop healthy meals rich in unsaturated fats and dietary fiber. CONCLUSIONS: The LOHAS food exchange table and LOHAS food pattern are expected to be practical tools for designing and evaluating nutritionally balanced diets.

Hyperfamiliarity for unknown faces (HFUF) is a rare disorder in which unfamiliar faces seem familiar. We report one case of HFUF syndrome. A 34-year-old woman was admitted as encephalitis with seizure. She repeatedly reported to her husband that all faces around her looked familiar. Our case supports the studies that show a differential contribution of two hemispheres in face recognition. Here we report this case for the first time in Korea.

Wilson's disease shows considerably various symptoms that sometimes timely diagnosis is delayed when patient shows vague clinical presentation. We present a female patient whose initial symptom was hypersomnia and severe fatigue. She was initially diagnosed as depression. Because initial hepatic function test was unremarkable, it was not easy to come to think about relationship between hepatic function and hypersomnia. Her final diagnosis was Wilson's disease. This case suggested that hypersomnia otherwise unexplained could be the presenting symptom of Wilson's disease.

Activities of daily living (ADL) refer to the ability to care for self and perform daily activities within an individual's place or in outdoor environments. ADL comprise two main categories: Basic or physical ADL and Instrumental ADL. The latter allows for the earlier detection of functional decline than the former. The cognitive changes in neurodegenerative dementias contribute to the impaired ability of the patients to take care of themselves. Activities of daily living is a major criterion for diagnosing dementia. Furthermore, it has recently been emphasized that some impairment of activities of daily living, particularly of complex instrumental functions, is already present even in mild cognitive impairment prodromal stage of dementia, although mild cognitive impairment is distinguished from dementia by the absence of significant deficit in activities of daily living. The impaired activities of daily living increase the rate of institutionalization of the patients with dementia to nursing home and inevitably bring about the changes in the qualities of life not only of the patients but their caregivers. One of the best ways to evaluate the degree of impairment in activities of daily living and the care burden is through standardized functional assessment tools according to the severity of dementia. These tools provide objective data, thereby allowing the clinicians to judge decline and improvement in the functional status and to plan individualized care. In this review, we will review the clinical significance of evaluating ADL, the assessment tools according to the severity of dementia, and therapeutic approaches to enhance the functional levels. We will also review the impact of the impaired ADL on the quality of life among the patients and their care providers.

Effective microorganism (EM) fermentation extract has been widely used for agricultural and environmental application. It has been recently revealed that EM cocktail treatment may be effective for treatment of diseases including cancer. In the present study, effectiveness of EM cocktail to control asthma was investigated using a mouse model of allergic asthma. Asthmatic mice sensitized and intranasally challenged with OVA were orally given EM fermentate (EM-1(R) during antigen challenge. Administration of EM-1(R) resulted in a significant reduction in airway hyper-reactivity (AHR) and airway recruitment of total leukocytes and eosinophils. Cytokine (IL-4, IL-5 and IFNgamma) levels in bronchoalveolar lavage fluid (BALF) and lung tissues were not altered by EM-1(R) treatment. However, IL-13 level in BALF was considerably lower in EM-1(R) treated mice than in controls. Moreover, Ag-specific IL-4, IL-5 and IL-13 production of draining lymph node cells were markedly downregulated by EM-1(R) treatment when compared to controls, whereas their IFNgamma production was not significantly different. Those data show that EM-1(R) treatment suppresses type 2 helper T (Th2), but not type 1 helper T (Th1), cell response. This finding was also supported by serum antibody data showing that IgE and IgG1 levels in EM-1(R) treated mice were significantly lower than in controls, while IgG2a level was not significantly different between two groups. In conclusion, oral administration of EM-1(R) attenuates asthmatic manifestations including AHR and airway recruitment of eosinophils in a mouse model and which possibly results from selective inhibition of Th2 cell response to allergen. Our data also suggest that EM-1(R) may be effectively applied for control of allergic asthma.
