Basta(R) is one of the Phospho-amino acid group herbicide. It consist of glufosinate ammonium (18.5%), alkylether sulfate as surfactant (30%) and some solvents. Although it's WHO classification is Bade III, the intoxicated patient appears an serious clinical findings and have a 20% mortality rate. Nowadays, in Korea the ingestion of herbicidal agents for suicidal attempts is Sequent. The literature for intoxication of bipyridilium (Gramoxon(R)) as herbicide is varied, but the information for Basta(R) is poor even though the use of it tends to increase. Recently, We experienced six cases of Basta(R) intoxication and found that the patient expressed a gradually progressed depression of mentation, recent memory disturbances, convulsions, hypotension, or bradycardia because of CNS or cardiovascular effects of Basta(R) We report these cases with literature review.

BACKGROUND: The growth of cells is closely related to components in a culture medium. There are many reports about cellular characteristics of melanocytes grown in a PMA-contained medium. However, only a few reports have been studied by using a physiologic mitogens-contained medium. To understand melanocyte in vivo, it is necessary to know the cellular biology of melanocytes grown in a physiologic mitogens-contained medium. OBJECTIVE: To investigate any differences between melanocytes grown in phorbol 12-myristate 13-acetate(PMA)-contained medium and in physiologic mitogens-contained medium. METHOD: We examined morphology, number and melanin contents of cultured human melanocytes grown in a PMA-contained medium and physiologic mitogens-, such as bFGF, ET-1 and a a-MSH contained medium. Result : The results are summarized as follows : 1. There were no significant morphologic differences between cells in PMA-contained medium and in physiologic mitogens-contained medium. 2. The number of melanocytes were significantly more numerous in PMA-contained medium on the 2nd day (p<0.05), but significantly less numerous in the same medium on the 6th day (p<0.05). So, the proliferation rate of melanocytes in PMA-contained medium became lower than in physiologic mitogens-contained medium as time went by. 3. Melanocytes grown in PMA-contained medium had significantly increased melanin contents regardless of the time (p<0.05). Conclusion : The proliferation of melanocytes was better in physiologic mitogens-contained medium, the melanization was higher in melanocytes of PMA-contained medium.

The frequency of metastasis to the skin from lung cancer is 1-12%. The incidence of cutaneous metastasis was high in patients with large-cell lung cancer, whereas squamous cell and small-cell lung cancer showed the least tendency to extend to cutaneous sites. Adenocarcinoma was intermediate in the tendency to metastasize in the skin. Histological findings of small-cell lung cancer show solid, tumor cell nests composed of neoplastic cells with large, round nuclei. So, it is often difficult to distinguish small-cell lung cancer from other poorly differentiated small-cell tumors, such as Merkel cell carcinoma, metastatic carcinoid, lymphoma, etc. We report here two cases of skin metastasis from small-cell lung cancer. Case one was a 74-year-old man presenting with a single, round, dome-shaped nodule on the alar nasi which had been present for 1 month. The second case was a 73-year-old man who had found three, non-tender, freely movable subcutaneous nodules on the abdomen 3 days before. Both cases were diagnosed as small-cell lung cancer. On histopathological examination of the skin lesions, we could observe that small round to oval cells with dark staining nuclei and scant cytoplasms were arranged in anastomosing trabecular streams through the dermis, separated by strands of connective tissue in both cases. In the first case, the tumor cells were positive to cytokeratin and NSE, negative to neurofilament antiagen and LCA.

PURPOSE: The purpose of this study is to analyze the structural model on the Nursing Task Performance of Hospital Nurses. METHODS: Data collection was done by the 200 hospital nurses from May 1st to May 20th, 2013 in Seoul city. The sample variance-covariance matrix was analyzed using AMOS 19.0 and the maximum likelihood minimization function. The goodness of fit was evaluated using the SRMR, RMSEA and its 90% confidence interval, CFI, and TLI. RESULTS: First, hospital nurses' organizational justice and empowerment was not found to have a significant direct effect on nursing task performance. Second, organizational justice and empowerment had a direct effect on job satisfaction and organizational commitment. Third, organizational commitment was found to have a significant direct effect on nursing task performance. Forth, hospital nurses' empowerment was found to have a significant direct effect on nursing task performance. CONCLUSION: Nurses' nursing task performance was influenced by organizational justice, empowerment, and organizational commitment. In order to increase the degree of nursing task performance in hospital nurse, it is necessary to develop the nursing program and its application considering hospital nurses' organizational justice and empowerment and organizational commitment.

BACKGROUND: Fixed drug eruptions(FDE) are a cutaneous reaction characterized by one or more circumscribed lesions that recur at the same site in response to a given medication. OBJECTIVE: The purpose of this study was to find the clinical and histopathological characteristics of FDE and to compare early FDE with late FDE histopathologically. METHOD: We clinically investigated 54 cases of FDE that visited the department of dermatology at the Kyunghee medical center from January 1993 to December 1996. Among them, 31 patients had skin biopsies and were evaluated histopathologically on the basis of duration. RESULTS: The results were summarized as follows: 1. Development of FDE did not show any difference according to sex and was evenly distributed over all the ages. 2. The latent periods of FDE were diverse in appearance from 30 minutes to 10 days, but mostly, the skin lesions erupted within 4S hours. 3. The most common skin lesions were erythematous macules. 4. Distribution of the lesions came out as solitary: 20.4%, multiple: 79.6%. S3.7% of the multiple lesions were localized to a part of body, and 16.3% were distributed over the whole body. 5. The areas in which the eruptions developed were (in descending order): upper extremity(37.0%), hand(31.5%), trunk(24.1%), face(24.1%). 6. In most cases(68.6%), the size and the number of lesions were greater in recurrente, rather than in first attacks. 7. The histopathological findings commonly showed perivascular mononuclear cell(MNC) infiltration (100%), pigmentary incontinence(77.4%), basal hydrophic degeneration(71.0%), eosinophil infiltration in dermis(61.3%), etc. 8. The epidermal histopathological findings such as spongiosis, exocytosis of MNC, basal hydrophic degeneration, keratinocyte necrosis and subepidermal vesicles could be seen more frequently in early lesions than in late ones. CONCLUSION: In our study, we were able to obtain meaningful results based on data from the combination of clinical and histopathological investigations. This study may give help to understand the characteristics of fixed drug eruptions and to plan future studies.

Autism Spectrum Disorder (ASD) is characterized by persistent deficits in social communication and restricted, repetitive patterns of behavior and interest. Sleep problems are not uncommon in children with autism spectrum disorders. Symptoms of insomnia are the most frequent sleep problems in individuals with ASD. Sleep problems can cause significant difficulties in the daily life of children with ASD and their families. Genetic factor, deregulations of melatonin synthesis, extraneous environmental stimuli and psychiatric and medical conditions may cause sleep problems. The first line treatment of sleep problems in ASD includes managements for potential contributing factors and parent education about sleep hygiene care for child and behavioral therapy. Supplementation with melatonin may be effective before considering other medications, such as risperidone, clonidine, and mirtazapine.

Bcl-2 is a proto-oncogene initially described in follicular lymphoma, associated with chromosomal translocation(14;18). Recent studies have shown the presence of Bcl-2 in nonhematolymphoid tissue, especially in hormonally responsive tissue. The endometrium is an attractive model for studying the hormone dependent regulation of Bcl-2 expression. We have studied the immunoreactivity of Bcl-2 oncoprotein in relation to the immunoreactivity of estrogen receptors(ER) and progesterone receptors(PR) by immunohistochemistry in 52 human endometrial carcinomas, according to nuclear grade. The results obtained are summarized as followings, 1) Immunohistochemical grade of Bcl-2 showed a significant inverse correlation with nuclear grade. 2) Immunohistochemical grades of ER and PR also showed a significant inverse correlation with nuclear grade, and were well correlated with each other. 3) Immunohistochemical grades of Bcl-2 and hormone receptors showed a strongly significant correlation. On the basis of the above results, we suggest that Bcl-2 expression may be under hormone dependent control and that it can be used in prognosis and choice of hormonal therapy in the presence of hormone receptor.
