JOURNAL FREE ACCESSWe compared the sensitivity of new Escherichia coli tester strains having the TolC outer membrane transport protein mutation (tolC strain), viz., WP2tolC, WP2tolC/pKM101, WP2uvrA,tolC and WP2uvrA,tolC/pKM101, with E. coli strains not carrying this mutation (non-tolC strain), i.e., WP2, WP2/pKM101, WP2uvrA and WP2uvrA/pKM101, by measuring the specific activity (revertants/mg) of mutagens using a preincubation method. The tolC strains were more sensitive to polycyclic and heterocyclic compounds such as 2-aminoanthracene, 2-nitrofluorene, Glu-P-1, benzo[a]pyrene, mitomycin C, streptonigrin and doxorubicin than the non-tolC strains. Mutagenicity of 2-nitrofluorene was not detected by non-tolC strains WP2, WP2/pKM101 and WP2uvrA, but was detected by their tolC counterpart strains WP2tolC, WP2tolC/pKM101 and WP2uvrA,tolC. However, these tolC strains were less mutagenic to streptozotocin or cisplatin than that of parent strains. Mutagenicity of 9-β-D-arabinofuranoside was also not detected by the tolC strain WP2uvrA,tolC/pKM101, but was detected by the non-tolC strain WP2uvrA/pKM101. The enhancing effects of the mutagen detecting sensitivity by TolC outer membrane transport protein mutation were clearly observed with the low sensitivity strain WP2, but less clearly with the high sensitivity strain WP2uvrA/ pKM101.View full abstractDownload PDF (977K) -

JOURNAL FREE ACCESSA novel oligosaccharide was purified from garlic (Allium sativum L.) bulbs via hot water extraction, ammonium sulfate precipitation, gel filtration and ion exchange chromatography. The molecular weight of the oligosaccharide was determined to be 1800. A nuclear magnetic resonance (NMR) study showed that ten fructose molecules were connected by β1-2 linkage to a terminal glucose. The oligosaccharide had cytotoxic activities against human malignant lymphoma cells (U937) and colon adenocarcinoma cells (WiDr) in vitro. Furthermore, this oligosaccharide significantly suppressed the growth of murine colon adenocarcinoma cells (colon 26) in vivo. The oligosaccharide also stimulated interferon-γ production by human peripheral blood lymphocyte in vitro, indicating that it may activate the immunological pathways and suppress the growth of tumors in vivo.View full abstractDownload PDF (569K) -

JOURNAL FREE ACCESSThe use of robotic-aided therapy in a patient with residual damage from a previous stroke was an attempt to improve function in a moderate to severe hemiparetic arm. Cortical activities associated with motor recovery are not well documented and require investigation. A chronic stroke patient with a severely affected arm underwent a robotic-training program for 12 weeks. The robotic-aided therapy improved motor control and spasticity in the proximal upper-limb. An increased oxygenated hemoglobin level was observed at the motor-related area in the affected hemisphere. A 12-week robotic-aided training program used in a chronic stroke patient demonstrated elements of motor recovery, and was also associated with direct activation of the affected hemisphere.View full abstractDownload PDF (616K) -

JOURNAL FREE ACCESSThe purposes of this study were to survey the actual conditions of the employment status and activities of occupational health nurses who are employed in Japanese Industrial Health Organizations (IHOs), and to investigate whether the OHNs provide quality health services to employees. We mailed 1,780 questionnaires to nurses who belong to 92 IHOs (members of the National Federation of Industrial Health Organizations). A total of 976 questionnaires were returned (54.8% valid response rate) and 968 questionnaires were considered eligible for analysis. The results showed the following issues: 1) most public health nurses belonged to the department of occupational health service, but they did not have enough experience with industrial hazards or workers safety or health; 2) public health nurses want to participate more directly in care for workers; 3) Public Health Nurses provided health counseling in the charge of their enterprises, but they did not take managerial roles, including place-of-work patrol, attendance to safety, and health committees in their workplaces; 4) they were not satisfied with the present roles demanded by the other staff and their managers; 5) they did not have enough opportunities to attend the job training. Together, the results of this study suggest that the OHNs in IHOs need to have more opportunities to perform their expertise in industrial health & safety and job training in order to provide autonomous health services to the workers.View full abstractDownload PDF (1967K) -

JOURNAL FREE ACCESSThe purpose of this survey was to clarify the relationship between the job characteristics of visiting nurses, their workload and their intent to continue their work. The self-administered questionnaire survey targeted visiting nurses at a home-visit nursing care agency in Fukuoka prefecture. The results revealed the following points. Nurses who felt that there was "a discrepancy between what they thought their job description would be and the reality," that there was "a lot more work besides visiting homes," that there were "so many situations that require them to make a decision" or that there were "so many complex nursing skills" were more likely to find their workload burdensome. The more positive they felt about "the future prospects of the nursing agency," "the number of nurses at work" or "their wages," the more likely they were to have the intention of working continuously. The survey also suggested that a raised level of labor-management awareness for managers would help improve the incentive to work for visiting nurses, and the realization of systematic continuing education as a proactive measure to alleviate reactions to difficult realities would also help nurses maintain the desire to work continuously.View full abstractDownload PDF (1050K) -

JOURNAL FREE ACCESSThe purpose of this study was to identify trends in nursing research on cancer patients' families published within the past 12 years (1996-September 2007, present) and examine their research themes. Five core categories were identified: 1) cancer nursing at home, 2) terminal care in a general ward, 3) family's experience in a terminal period and after bereavement, 4) family's experience and care during treatment, and 5) family systems. Findings showed that the following areas of research are being conducted: nursing research on a variety of therapies and care environments, research on nurses' awareness of the families of cancer patients and how this affects treatment, interventional research on how to implement study findings, and research activities based on family nursing.View full abstractDownload PDF (1714K) -

JOURNAL FREE ACCESSCommuting transportation is one of the important factors in the administration of safety management in industries. Most workers commute to work by car and are certain to make use of highways, mainly because of the special condition of factory locations. In this study, we investigated the effect of communicating by car on the health of factory workers. The proportion of males was significantly higher in the highway (HW) group than in the non-highway (NHW) group, and the former was younger than the latter. BMI, systolic blood pressure, diastolic blood pressure, and total cholesterol deteriorated significantly in the NHW group after 5-year periodic medical checkups. However, in the HW group, those factors did not change except for systolic blood pressure and significant improvements in triglyceride. The percentage of those who follow a good lifestyle regarding excise and nutrition, and have a solution for stress, was lower in the HW group than in the NHW group. Nevertheless, the percentage of those who did not feel stress was significantly higher in the HW group than in the NHW group, suggesting a stress-relieving effect of highway driving. Highway driving might have an unexpectedly good impact on the health of factory workers.View full abstractDownload PDF (387K) -

JOURNAL FREE ACCESSThe purpose of this paper is to present the differences and similarities in the roles of occupational health nurses(OHNs) between the United States and Japan by reporting the results of interviews with seven OHNs who work at seven industries in the city and the suburbs of San Francisco. Four out of seven OHNs responded that one of their essential roles was "Case Manager", in regard to the prevention of work force reduction and the scaling back of workers' medical expenditures associated with work-related accidents. Only one of them responded that "Health Promotion Specialist" was the leading role, whereas 30% of the Japanese OHNs were engaged in this role, according to the results of a previous study. Similarly to the other roles of the Japanese OHNs, they also consider Clinicians, Managers, and OHS Coordinators as their important roles. Together, the result of interviewing the nurses indicated that the differences in the role delineation of the OHNs between the two countries depend upon their educational system of licensing as well as implementation of their responsibilities to the laws and regulations, including the Occupational Health and Safety Act, health examination of the OSHA Standard and employment of occupational medical doctors, medical insurance and compensation for workmen's accidents, etc. Furthermore, this visiting opportunity gave the authors suggestions for the advancement of educational programs to reinforce the professional activities of occupational health nursing in Japan.View full abstractDownload PDF (1387K)
