In this study the authors observed the status of water contamination by crayfish, Cambaroides similis, either alive or dead infected with Paragonimus westermani. The crayfish used as materials were infected heavily with metacercariae of Paragonimus westermani. The live crayfish were kept in water for a long time, and then the sediments of the water were examined to find out whether or not the liberation of the metacercariae from the body of the crayfish had caused contamination of the water with metacercariae. Killed crayfish were also preserved in water for some time. Physical stimuli in terms of mederate degree of shaking were added to the preserved water once a day and half amount of the water was replaced with tapped water of same temperature everyday. Status of the decay of the crayfish, liberation of the metacercariae from the body of the crayfish or contamination of the preserved water by the metacercariae, and numbers of metacercariae harboured in the body of the crayfish were examined everyday. The fate of the metacercariae liberated from the crayfish into water was also observed. Status of the decay of the crayfish, liberation of the metacercariae from the body of the crayfish or contamination of the preserved water by the metacercariae, and numbers of metacercariae harboured in the body of the crayfish were examined everyday. The fate of the metacercariae liberated from the crayfish into water was also observed. The results of this study can be outlined as follows: No metacercaria was detected in the water which contained live crayfish infected with Paragonimus westermani. The preserved water with dead or killed crayfish was found to be contaminated by the metacercariae of Paragonimus westemani, which had been caused by the decay and dispersion of the flesh of the crayfish The liberated metacercariae survived for 10 days in the water at 21-27 C. The liberated metacercariae were found to be sinking into water of s.g. 1.000 with average velocity of 35.8 cm per minute.

STATEMENT OF PROBLEM: To improve a direct implant fixation to the bone, various strategies have been developed focusing on the surface of materials. The surface quality of the implant depends on the chemical, physical, mechanical and topographical properties of the surface. The different properties will interact with each other and a change in thickness of the oxide layer may also result in a change in surface energy, the surface topography and surface, chemical composition. However, there is limited the comprehensive study with regard to changed surface and biologic behavior of osteoblast by anodization. PURPOSE OF STUDY: The aim of this study was to analyze the characteristics of an oxide layer formed and to evaluate the cellular biologic behaviors on titanium by anodic oxidation (anodization) by cellular proliferation, differentiation, ECM formation and gene expression. And the phospholipase activity was measured on the anodized surface as preliminary study to understand how surface properties of Ti implant are transduced into downstream cellular events. METHODS AND MATERIALS: The surface of a commercially pure titanium(Grade 2) was modified by anodic oxidation. The group 1 samples had a machined surface and other three experimental specimens were anodized under a constant voltage of 270 V(Group 2), 350 V(Group 3), and 450 V(Group 4). The specimen characteristics were inspected using the following five categories; the surface morphology, the surface roughness, the thickness of oxide layer, the crystallinity, and the chemical composition of the oxide layer. Cell numbers were taken as a marker for cell proliferation. While the expression of alkaline phosphatase and Runx2 (Cbfa1) was used as early differentiation marker for osteoblast. The type I collagen production was determined, which constitutes the main structural protein of the extracellular matrix. Phospholipase A2 and D activity were detected. Results. (1) The anodized titanium had a porous oxide layer, and there was increase in both the size and number of pores with increasing anodizing voltage. (2) With increasing voltage, the surface roughness and thickness of the oxide film increased significantly (p<0.01), the TiO2 phase changed from anatase to rutile. During the anodic oxidization, Ca and P ions were more incorporated into the oxide layer. (3) The in vitro cell responses of the specimen were also dependant on the oxidation conditions. With increasing voltage, the ALP activity, type I collagen production, and Cbfa 1 gene expression increased significantly (p<0.01), while the cell proliferation decreased. (4) In preliminary study on the relation of surface property and phospholipase, PLD activity was increased but PLA2 activity did not changed according to applied voltage. CONCLUSION: The anodized titanium shows improved surface characteristics than the machined titanium. The surface properties acquired by anodization appear to give rise more mature osteoblast characteristics and might result in increased bone growth, and contribute to the achievement of a tight fixation. The precise mechanism of suface property signaling is not known, may be related to phospholipase D.

Herpes zoster involving noncontiguous dual dermatomes is very rare in both immunocompetent and immunocompromised persons. This unique presentation has been referred to as zoster duplex unilateralis or bilateralis, depending whether one or both halves of the body are involved. A 22-year-old woman, who had been treated for acute leukemia, congestive heart failure and chronic disseminated candidiasis, was referred to our department for painful papulovesicular eruptions on the right side of the anterior chest and upper back for 2 days, and the left buttock for 1 day. Tzanck smear revealed multinucleated giant cells with intranuclear inclusion bodies. We report a rare case of zoster duplex bilateralis.

Desmoplastic malignant melanoma (DMM) is an uncommon variant of malignant melanoma featuring a proliferation of spindle cells with pronounced desmopaasia. DMM commonly occurs on the sun-damaged skin such as head and neck in older persons, and it can be associated with lentigo maligna. We report an unusual case of desmoplastic malignant melanoma that developed de novo on the trunk in a young patient.

Venous hemangioma is a vascular tumor that has been reported by such diverse names as; "cirsoid aneurysm", "arteriovenous hemangioma", "acral arteriovenous tumor" according to the author's opinions of its origin and histopathologic classification. It is benign and rarely biopsied, and it is also rarely reported in dermatology literature. We present two cases of venous hemangioma. The first case was a 64-year-old man who was presented with an elliptical dark-red plaque with overlying several grouped papules on the left periorbital area which had been present for 7 years. The second case was a 56-year-old man who was presented with a single red papule on the right postauricular area which had been present for 4 months. Histopathologically, there were a well-circumscribed proliferation of thick-walled muscle-containing blood vessels in the dermis. Intermingled with the thick-walled blood vessels, there were also thin-walled dilated blood vessels. In both cases, the thick-walled blood vessels resembled arteries, but they lacked elastic fibers on the Verhoeff van Gieson stain.

PURPOSE: The study was undertaken to investigate influence of nurses' work environment, organizational commitment, and nursing professionalism on turnover intention of nurses working in long term care hospitals. METHODS: The study was cross-sectional study. Participants were 199 nurses working in one of 7 long term care hospitals. Data were collected from May 1 to June 30, 2016 and analysed using two stage hierarchial regression analysis with SPSS 22.0. RESULTS: There was a statistically significant difference in turnover intention according to age (F=6.23, p < .001), present work career (t=−2.11, p=.036), frequency of night duty (t=−3.53, p=.001), and present position (t=−4.07, p < .001). The significant predictors of turnover intention were attachment (β=−0.29, p=.005), nursing professionalism (β=−.21, p=.030), identification (β=−.21, p=.014), continuance (β=−.19, p=.008), collegial nurse-physician relations (β=−.16, p=.039), and originality of nursing (β=.16, p=.014). These factors explained 50.4% of the variance. CONCLUSION: The results suggest that several points need to be considered in order to reduce turnover intention in long term care hospital nurses. These points include building work environments to improve collegial nurse-physician relations, promoting recognition of nurses' organizational commitment, nursing professionalism and the political efforts of organizations supporting nursing originality.
