In order to exmaine the mutagenicity of cadmium dichloride the author studied the induction of sister chromatid exchanges in chinese hamster ovary K1 cells which treated with cadmium dichloride at various concentrations. The results obtained were as follows: 1. In cells treated with 10(-4) M cadmium dichloride, a small number of cells were visable but no mitosis was bound. 2. The frequencies of sister chromatid exchanges in cells treated with 10(-5) M and 10(-6) M cadmium dichloride as 10.7 +/- 1.9 and 8.3 +/- 2.1, respectively, were significantly increased for control (6.0 +/- 2.3). (p<0.05). 3. There were dose-dependent relationship between the concentration of cadmium dichloride and frequency of sister chromatid exchanges in cells treated with cadmium dichloride at concentration ranging from 10(-5) to 10(-7) M.

OBJECTIVE: Identification of the regulatory mechanism for arrest and initiation of primordial follicular growth is crucial for female fertility. Previously, we found 15 expressed sequence tags (ESTs) that were specifically abundant in the day-5-subtracted cDNA library and that the B357 clone was novel. The present study was conducted to obtain the whole sequence of the novel gene including B357 and to characterize its mRNA and protein expression in mouse ovary and testis. METHODS: The extended sequence of the 2,965-bp cDNA fragment for the clone B357 was named 5-day-ovary-specific gene-1 (5DOS1) and submitted to GenBank (accession number AY751521). Expression of 5DOS1 was characterized in both female and male gonads at various developmental stages by Northern blotting, real-time RT-PCR, in situ hybridization, Western blotting, and immunohistochemistry. RESULTS: The 5DOS1 transcript was highly expressed in the adult testis, brain, and muscle as compared to the other tissues. In the ovary, the 5DOS1 transcript was detected in all oocytes from primordial to antral follicles, and highly expressed at day 5 after birth and decreased thereafter. In contrast, expression of 5DOS1 showed a gradual increase during testicular development and its expression was limited to various stages of male germ cells except spermatogonia. CONCLUSIONS: This is the first report on the expression and characterization of the 5DOS1 gene in the mouse gonads. Further functional analysis of the 5DOS1 protein will be required to predict its role in gametogenesis.

PURPOSE: This study was conducted to examine the factors associated with work related injuries of nurses in small and medium sized hospitals. Method: A cross-sectional survey was conducted with nurses in eight hospitals from October 2007 to January 2008. A questionnaire was designed to collect information on nurses' work related injuries, and individual and job related characteristics. The response rate was 65.1%. Data from 294 nurses were analyzed. Multiple logistic regression analysis was performed to determine factors associated with work related injuries. Result: Of the 294 nurses, 19.1% (n=56) responded as having at least one injury during their job performance. The logistic regression analysis revealed that the significant factors influencing work related injuries were job satisfaction, stress recognition, and hospital's location. Nurses with a higher job satisfaction were less likely to experience work related injuries (OR=0.58). Nurses with a higher stress recognition (OR=2.57) and those working at hospitals in metropolitan cities (OR=3.28) were more likely to experience work related injuries. CONCLUSIONS: The result of this study indicated that a substantial proportion of nurses in small and medium sized hospitals had experienced injuries related to nursing job. Interventions to prevent work related injuries among nurses should take into account the job satisfaction, stress recognition, and hospital characteristics.

The present report deals with the behaviour of mast cells in mice in the course of Entamoeba histolytica infection by the strains. Mice weighing about l6 gm were used for three experimental groups; control, sham infection and experimental. The experimental group was infected with Entamoeba histolytica trophozoites directly into cecum by laparotomy. Strains isolated from three hepatic amoebic abscess cases were used. Mesenteric samples from the region of terminal ileum were fixed in methyl alcohol and stained with Pugh's solution. The ulcers in cecum were examined. Changes in number and structure of mesenteric mast cells and blood eosinophils were as follows. The number of mast cell in mesenteric tissues of the infected group increased from first day of the infection and persisted up to 34th day of the observation period. Degranulation and disruption of mast cells increased in the infected group compared with groups of the sham operation and the contro1, but showed no difference by the strains of Entamoeba histolytica. The blood eosinophilia was observed in the infected group and persisted until the observation period. Ulcers in cecum were found in all the infected groups. The results above indicate that mast cells are keenly related with the course of Entamoeba histolytica infection.
