PURPOSE: This study was conducted to investigate gender stereotype and job satisfaction, and to identify the relationship between gender stereotype and job satisfaction in male nurses. METHODS: The participants were 165 male nurses who worked in the Seoul, Gyeonggi and Daejeon areas. Data were collected from August 31th, 2009 to October 15th, 2009. A survey questionnaire was used to measure demographics, gender-role identity, gender stereotype and job satisfaction. Data were analyzed using SPSS/Win 12.0 version. RESULTS: The mean score for gender stereotype was 2.81 points out of a possible 5. There were statistically significant differences in gender stereotype by general characteristics such as career in the current department (F=5.249, p=.007) and position (t=2.547, p=.012). The scores for gender stereotype were significantly higher in the group with less than five years in the current department and in the staff nurse group. The mean score for job satisfaction was 2.95 out of a possible 5. There was a significant negative correlation between gender stereotype and job satisfaction. CONCLUSIONS: Development of educational programs is required to improve the gender stereotype.

PURPOSE: This study was conducted in order to investigate the effects of an aerobic exercise program on mobility, fall efficacy, balance, and stress in the elderly at senior centers. METHODS: This research was conducted as a quasi-experimental pretest and posttest control and experimental comparison study. The subjects were 41 senior residents (Exp.=18, Cont.=23) who aged above 65 at senior centers in S City. The period of time for data collection and intervention was from August 25 to December 5, 2008. RESULTS: Mobility (t=-3.10, p<.01) in the experimental group were significantly higher than those in the control group without an aerobic exercise program. However, fall efficacy (t=1.28, p=.207), balance (t=-.53, p=.602; t=.36, p=.723), stress (t=-1.32, p=.199) in the experimental group was not significantly higher than that in the control group. CONCLUSION: These findings confirmed that aerobic exercise programs make a contribution to improving mobility in the elderly at senior centers.

PURPOSE: The purpose of this study was to investigate the effects of perceived stress on cognition in the community elderly. METHODS: This was a descriptive study. Data were collected using individual-based interviews from 40 senior residents at the hall for the elderly in S City. The period of data collection was from June 19 to July 7, 2006. The tools of data collection were Mini-Mental State Examination (Folstein, Folstein, & McHugh, 1975) and Perceived Stress Scale (Cohen, Kamarck, & Mermelstein, 1983). RESULTS: Cognition showed significant differences according to gender, education, and regular exercise. Cognition was significantly correlated to stress and age. Stress was significantly correlated to orientation, recall, and attention/calculation. In the results of stepwise multiple regression, factors affecting cognition were stress, age, and gender. CONCLUSION: It is necessary to prepare health promotion programs that can reduce stress level in the community elderly.

Toxoplasma gondii infection induces parasite infiltration and apoptosis in the spleen. However, dose-dependent parasite infiltration, apoptosis, body weight alternations and survival in mice remain largely unknown. In this study, mice were intraperitoneally infected with 10, 30 or 100 tachyzoites of T. gondii, respectively. Parasite infiltration and apoptosis in the spleen were analyzed on days 3, 7, and 9 post-infection by immunohistochemistry and flow cytometry. Significantly higher levels of T. gondii infiltration and apoptosis in the spleen were found in 30 and 100 tachyzoites infected mice compared to 10 tachyzoites infected mice on days 7 and 9 post-infection. Although 30 and 100 tachyzoites infected mice showed significant body weight loss compared to 10 tachyzoites infected mice, all of the 100, 30, and 10 tachyzoites infected mice died by days 12, 15, and 17, each respectively. Interestingly, T. gondii infiltration in 10 tachyzoites infected mice were limited to capsule area of the spleen on day 9 post-infection. Several areas of parasite infiltrations were found in the 30 tachyzoites infected mice, where noticeable levels of splenic capsule de-adhesion occurred. These results indicated that parasite infiltration and apoptosis in the spleen, as well as body weight loss (survival) are closely correlated with infection dosage. The level of T. gondii infiltration and apoptosis in the spleen and splenic de-adhesion were dependent on the parasite dose.

Accurate diagnosis and management of a femoral vascular injury is important as it is a life-threatening injury with high morbidity and mortality. This is the case of a 75-year-old man admitted to the emergency room with trauma to the right groin due to a horse fall. Computed tomography showed active bleeding of the femoral artery without pelvic or femoral fracture. We inserted a stent-graft, but hypotension persisted. Exploration of the groin was completed, and the bleeding from the external iliac vein was identified and repaired. In conclusion, vascular injury is rare in groin trauma without associated fracture, however, arterial and venous injury should not be completely ruled out. Endovascular therapy is worth recommending as a quicker and safer management than surgery in patients with active bleeding in the femoral artery. However, the possibility of combined injury of the femoral vein should be suspected in case of ongoing hemodynamic instability.

Rupture limited to the lobar bronchus from blunt trauma is especially rare, and the symptoms are light so diagnosis is difficult. In a patient who visited the hospital complaining of shortness of breath after falling down, atelectasis continued in the chest x-ray. Four days after visiting the hospital, a left upper lobar bronchial rupture was diagnosed through a bronchoscopy and 3 dimensional chest computerized tomography. When diagnosis is delayed in the case of a rupture limited to the lobar bronchus, bronchial obstruction can occur from the formation of granulation tissue, so regular monitoring is important. Therefore, when atelectasis continues after blunt trauma, it is important to differentially diagnose a lobar bronchial rupture through tests such as bronchoscopy.

In the conservative management of uterine fibroids is radiofrequency ablation (RFA) considered to be one of the safe, effective and minimal invasive approaches in selected women who desire to retain their uterus. Few studies were conducted on its adverse outcomes and most of the reported complications were minor events such as pain, discharge, adhesion which didn't require any intervention. However, although safe and effective, the RFA of a uterine myoma can be the cause for severe complications such as penetration and burn injuries of pelvic organs. In general, a rectouterine fistula is one of the rarest complications but can lead to serious adverse outcomes. Herein, to our knowledge, we report the first case involving a rectouterine fistula after laparoscopic ultrasound-guided RFA of a uterine myoma with pelvic endometriosis. In addition, we provide a brief review of the relevant literature.

Toxoplasma gondii is a ubiquitous protozoan parasite responsible for causing toxoplasmosis. Preventive measures for toxoplasmosis are currently lacking and as such, development of novel vaccines are of urgent need. In this study, we generated 2 virus-like particles (VLPs) vaccines expressing T. gondii rhoptry protein 4 (ROP4) or rhoptry protein 18 (ROP18) using influenza matrix protein (M1) as a core protein. Mice were intranasally immunized with VLPs vaccines and after the last immunization, mice were challenged with ME49 cysts. Protective efficacy was assessed and compared by determining serum antibody responses, body weight changes and the reduction of cyst counts in the brain. ROP18 VLPs-immunized mice induced greater levels of IgG and IgA antibody responses than those immunized with ROP4 VLPs. ROP18 VLPs immunization significantly reduced body weight loss and the number of brain cysts in mice compared to ROP4 VLPs post-challenge. These results indicate that T. gondii ROP18 VLPs elicited better protective efficacy than ROP4 VLPs, providing important insight into vaccine design strategy.

Both Plasmodium spp. and Toxoplasma gondii are important apicomplexan parasites, which infect humans worldwide. Genetic analyses have revealed that 33% of amino acid sequences of inner membrane complex from the malaria parasite Plasmodium berghei is similar to that of Toxoplasma gondii. Inner membrane complex is known to be involved in cell invasion and replication. In this study, we investigated the resistance against T. gondii (ME49) infection induced by previously infected P. berghei (ANKA) in mice. Levels of T. gondii-specific IgG, IgG1, IgG2a, and IgG2b antibody responses, CD4+ and CD8+ T cell populations were found higher in the mice infected with P. berghei (ANKA) and challenged with T. gondii (ME49) compared to that in control mice infected with T. gondii alone (ME49). P. berghei (ANKA) + T. gondii (ME49) group showed significantly reduced the number and size of T. gondii (ME49) cysts in the brains of mice, resulting in lower body weight loss compared to ME49 control group. These results indicate that previous exposure to P. berghei (ANKA) induce resistance to subsequent T. gondii (ME49) infection.
