We investigated the antitumor effect of simultaneous low-intensity, 150 kHz ultrasound, in combination with the anticancer drug doxorubicin (DOX) on breast adenocarcinoma using murine model (Balb/c).   Materials and Methods: Forty-four mice were used in this study. The tumor-bearing mice were divided into five groups, namely, control, sham, drug, drug+US and exposure to ultrasound alone . The administrated dose of DOX was 2 mg/per i.v, and the time of exposure was 30 minutes.   Results: We showed that, after the injection of DOX, exposure to ultrasound at 150 kHzcon potentiates the effect of doxorubicin on the growth of adenocarcinoma tumors compared to control group by two folds. The tumor growth inhibition percent in the groups treated by ultrasound and doxorubicin showed an increase compared with the group treated with doxorubicin alone. The total tumor growth inhibition percent (days 3-21) in the drug alone, drug+150 kHz groups was 23(%), 55(%), respectively . There was also a significant difference between the drug-treated group and the drug+US groups in times needed for each tumor to reach 2 and 7 times its initial volume (T2 and T7).   Conclusion: The co-administration of DOX and low-intensity ultrasound provided a more effective treatment than the drug alone in murine breast cancer. The combined treatment appeared to produce synergistic effects that are potentially useful in reducing the side effects of DOX by lowering the required effective dose of the drug while increasing the efficiency of the therapy as a whole.

Various methods and drugs have been used for the prevention of postoperative shivering. In this study, we have investigated the pretreatment effect of ondansetron and meperidine in reducing shivering after cesarean elective by spinal anesthesia.   Materials and Methods: In this double-blind study, 100 volunteered patients for cesarean elective using spinal were blocked and classified randomly into two groups. After the baby was born, 8 mg/kg ondansetron for the first group (O) and 0.4 mg/kg meperidine for the second group (M) was injected slowly. MAP, Heart rate and SPO2 were measured and recorded before the operation, during the operation and after the operation. The shivering or its absence was recorded for 20 minutes after the operation by a recovery nurse.   Results: The incidence of postoperative shivering was 10% in ondnasetron group and 24% in meperidine group. But there was no significant difference between the two groups.   Conclusion: There was not a significant difference between the effects of ondansetron and meperidne groups.

It is the second common cancer (after lung cancer) in women. Zingiber afficinale is used as a traditional medicine. Recently, the biological activities of Zingiber afficieale plants have been reported as possessing anticancer, antibacterial, antiulcer, antifungal, and insecticidal properties. However, the antitumor effects of this medicine have not been studied in cancer cell lines. The aim of this study was to investigate the antitumor effect of Zingiber afficieale on breast cancer cell lines.   Materials and Methods: Breast cancer (MCF7) cell lines and normal connective tissue cell line (L929) were cultured in DMEM medium. Zingiber afficinale was extracted and different dilutions of Zingier extract (1.60 to 1.200) were added to cell culture. Cell viability was quantitated by MTT assay after 24, 48 and 72 hours.   Results: The effects of Zingiber afficieale on cell viability were observed after 48 hours on cell lines. Ginger doses in dilution 1.100 and 1.70 inhibited 50% cell growth (IC50) in MCF7 cell line after 48 hours of incubation, respectively.   Conclusion: Our study shows that ginger fresh extract has cytotoxic effects on tumor cells, but it does not have any cytotoxic effect on normal cells. It seems that ginger could be considered as a promising chemotherapeutic agent in cancer treatment.

The most common alternative treatment method for patients is hemodialysis. Adherence to diet and fluids combined with dialysis is the cornerstone of renal failure treatment. By informing hemodialysis patients, we can help them have a proper diet and reduce mortality and complications of toxins. Face to face education is one of the most common methods of training in health care systems. But advantages of video training are easy and cost-effective but it is something virtual. So, the aim of this study was to assess the comparison of face to face and video-based education on attitudes related to diet and fluids adherence in hemodialysis patients. Materials and Methods: This study is a randomized clinical trial which included 75 hemodialysis patients admitted to the hemodialysis wards in 17 Shahrivar and Quaem hospitals in Mashhad. They were divided randomly into face to face and video-training groups. In the face to face educational group, 2 educational sessions were accomplished during dialysis with a one-week time interval. In the video-based educational group, a produced film, separated to two episodes, was presented during dialysis within a one-week time gap. An Attitude questionnaire was completed as a pre-test at the end of the second and fourth weeks. SPSS software version 11.5 was used for data analysis. The data were analyzed using Mann-Whitney test, t-student for two independent groups, Chi-square, Fischer exact test, and Krosal valice. Results: The two groups did not have a significant difference in demographic features. Attitude about fluid and diet adherence at the end of second and fourth weeks was not significantly different in face to face or video-training groups, respectively, (p=0.114, p=0.06). Patients' attitude had a significant statistical difference in face to face group between 3 study phases (pre-, 2 and 4 weeks post intervention, p=0.000). The same results were obtained in three phases of video-training group. (For 2nd week p=0.000, for 4th week p=0.001) Conclusion: Despite the belief that face to face method is more effective our findings showed that video training could be as effective. It is recommended that more investment be paid to video training.

This study aims to find the mental health situation related to different variables.   Materials and Methods: This is a cross-sectional and descriptive study. One hundred martyrs' widows and the same number of war veterans' spouses were selected and divided into two groups by systematic randomized sampling from among the list of those followed up by Zahedan War Veterans Foundation. Mental health of the individuals in the study was assessed by "General Health Questionnaire" and also semi-structural interviews. The data were analyzed by ANOVA and Toky Post Hoc Test.   Results : The results revealed that the mean scores of both groups and also 70% of the whole number of contributors in the study were higher than the GHQ cut-off point. Comparing the means in GHQ scores of the two groups showed no statistically significant difference. Women whose husbands had physical injuries showed a better mental health than those with mentally ill husbands (p=0.001).   Conclusion: The findings of this study in concordance with other similar researches confirm that generally martyrs' widows and war veterans' spouses suffer from low level of mental health. The relationship between the type of injury and mental health of veteran' spouses calls for special cares and services for different groups.   Family mental health war Zahedan 2011 9 01 43 50 http://imtj.gmu.ac.ir/article-1-1289-en.pdf

It occurs due to the inappropriate conditions in the workplaces. The purpose of this study was to determine the prevalence of low back pain and some related factors in nurses employed in Gonabad hospitals. Materials and Methods: This study is a descriptive cross-sectional research. It was carried out on 93 nurses who were working in Gonabad hospitals in 2010. The data were collected by a self-made questionnaire and analyzed by SPSS V.14 using descriptive statistics, Chi–square and t–student. Results: 61.3% (57 persons) of the patients were women and 38.7% (36 persons) men. 20% of them had another part time job in addition to nursing. 76.3% of cases had some knowledge about proper care of vertebral column although 12.9% used these cares. 50.5% of cases were also suffering from at least one type of low back pain. Lower vertebral column pain was the most common type of low back pain. There was a significant statistical relationship between pain and years of work (p=0.01).There was a significant statistical relationship between pain and age (p=0.001), pain and sex (p=0.02), pain and BMI (p=0.05), as well. Nurses with back pain had greater knowledge than those without the pain. Conclusion: High prevalence of vertebral column pain suggests the necessity for proper planning to reduce pain in the vertebral column. Regarding the effect of BMI on vertebral column pain, planning for weight reduction is necessary. Nurse pain vertebral column 2011 9 01 51 57 http://imtj.gmu.ac.ir/article-1-1286-en.pdf
