Authors' presented an interesting case, 19 years old boy, who was been suffered from retinal periphlebitis of both eyes which thought to be induced by Barre Syndrome. This patient also has pulmonary tuberculosis and visual symptoms of Barre Syndrome in this case were ocular pain and visual disturbance that appeared and disappeared suddenly due probably to irritation of the ventral nerve roots (C5 to T1) with also irritation of sympathetic fibers contained in them.

In vitro culture of Toxoplasma gondii in HL-60 cells cnd cell-mediated immunity against Toxoplasma in dimethylsulfoxide(DMSO)-induced HL-60 cells, i.e., differentiation into granulocytes, were pursued. HL-60 cells were treated with various concentrations of DMSO, and 1.3%(v/v) for 3 day incubation was chosen as the optimal condition for differentiation into granulocytes. The degree of differentiation was assayed in physiological and functional aspects in addition to morphological point. When treated with 1.3% DMSO for 3 days, HL-60 cells did not synthesize DNA materials beyond background level, and showed active chemotactic response to chemotactic peptide, formyl-methionyl-leucyl-phenylalanine(FMLP). Morphologically promyelocytes of high nuclear/cytoplasmic(N/C) ratio changed to granulocytes of relatively low N/C ratio. The relationships between HL-60 cells or DMSO-induced HL-60 cells and Toxoplasma were examined after stain with Giemsa and fluorescent dye (acridine orange). HS-60 cells did not show any sign of toxoplasmacidal activity but showed intracellular proliferation of Toxoplasma to form rosette for 72 hr co-culture. In contrast, DMSO-induced HL-60 cells phagocytosed Toxoplasma within 1 hr, and performed a process of intracellular digestion of Toxoplasma thereafter. With the above results, it is suggested that phagosome-lysosome fusion is one of the critical events for the parasitism by Toxoplasma or for susceptibility of host cells. The in vitro culture system of this study has offered a defined condition to study the protozoan parasite-host cell interactions.

BACKGROUND: The purpose of this study was to survey hygiene behavior of healthcare personnel according to the Hygiene Inventory 23 (HI23) and to use the results in education and research for promoting hygiene behaviors. METHODS: We sampled a total of 400 people with 50 from each job category. The sample was obtained through convenient sampling among 8,200 employees working at a tertiary-care hospital with 2,600 beds in Seoul. The HI23 consisted of 5 subscales and 8 questions on general hygiene, 3 on household hygiene, 3 on food-related hygiene, 5 on hand hygiene methods, and 4 on personal hygiene, resulting in a total of 23 questions. The researcher also added 14 questions on the general characteristics of the subjects. The self-administered questionnaires were distributed on October 2009 and analyzed blindly. RESULTS: The average total score for hygiene behavior was 3.04+/-0.44 (maximum of 4). In the subcategory of hygiene behavior, the mean score was 3.20+/-4.24 for general hygiene, 3.07+/-0.68 for household hygiene, 3.07+/-0.68 for food-related hygiene, 2.91+/-0.69 for hand hygiene methods, and 2.97+/-0.48 for personal hygiene. When factors affecting the level of hygiene behavior were identified through multivariate regression analysis, independent factors were found to be gender (female), job category (food-related job), experience in hand hygiene education, and experience in teaching hand hygiene or general hygiene. CONCLUSION: Programs and education adapted to the characteristics of each job category in hospitals are needed to promote hygiene behaviors such as general hygiene, hand hygiene methods, household hygiene, food-related hygiene, and personal hygiene.
