    Phytoextraction is a remediation technology that uses plants to remove heavy metals from soil. The success of a phytoextraction process depends on adequate plant yield (aerial parts) and high metal concentrations in plant shoots. A pot experiment was conducted to investigate the combination effects of plants [sunflower (Helianthus annuus) and canola (Brassica napus)] with soil treatments (manure, sulfuric acid and DTPA). Treatments, included two plants and seven soil treatments, which were applied baeed on a completely randomized factorial design. Three replicates were used for each treatment.. The largest shoot dry weight biomass production occurred in manure treatments for both plants. The maximum shoot concentrations of Pb and Zn were 234.6 and 1364.4 mg kg-1 respectively in three mmoles DTPA kg-1 treatment of sunflower. Furthermore the results showed that sunflower had a higher extracting potential for removal of Pb and Zn from polluted soil

    Introduction: Today, Epidemic of HIV / AIDS is one of the most important health, social, economic problems of human and one of the biggest problems and concerns in many countries of the world that its scope and size is still increasing. This study was performed with aim to determine the effect of educational intervention based on SET on behaviors of prevention of HIV/ AIDS in high risk and vulnerable women in the city of Neka. Methods: This Quasi- experimental (case-control) study was performed on 70 high risk and vulnerable women referred to Drop-In Centers (DIC) in Sari and Neka. Data was gathered using a researcher-made along with completing questionnaire. According to the results obtained from primary completing of the questionnaire, educational intervention was designed based on the SET and was performed in intervention group. After 3 months of intervention, data of both groups was collected and analyzed using SPSS software (version 16) and Chi-square, Mann-Whitney, Wilcoxon, independent t, and paired t tests. PResults: After educational intervention, use of condom was increased at intervention group (45,7) compared to control group (5,7). The difference between before and after of self- efficacy was significant in intervention group (9.83±0.05) and control group (1.50±2.67) and performance in the intervention group with median and interquartile range of 2.0 (3.0) and control group 0.0 (0.0). In intervention group, there was a significant relation between increase of self-efficacy and increase in performance (P<0,001). Conclusion: Behaviors of prevention of AIDS and self-efficacy is insufficient in the studied women and educational intervention based on the SET can be effective on promotion of self-efficacy and use of condom to prevent from AIDS in these women. © 2015, Iranian Journal of Obstetrics, Gynecology and Infertility.

A total of 122 opioid-dependent patients with acute pain were included in the study. Their pain severity was assessed, using visual analog scale (VAS) scores ranging from 0 to 10. The patients randomly received intravenous morphine (up to 0.15 mg/kg) or meperidine (up to 1.5 mg/kg) for pain control by patient control analgesia (PCA) pump. The clinical opioid withdrawal scale (COWS) was employed for the assessment of withdrawal symptoms. The pain relief and the emergence of withdrawal symptoms were measured at 15, 30, and 60 minutes after drug administration. The patients who received morphine reported a better pain control compared to those who received meperidine (mean &plusmn; standard deviation [SD] VAS scores 4.11&plusmn;1.90 vs 5.85&plusmn;2.08 at the end of the study; P&lt;0.001). On the other hand, the patients who received meperidine indicated prominent withdrawal symptoms (mean &plusmn; SD COWS scores 4.80&plusmn;2.18 vs. 1.98&plusmn;0.82 at the end of the study; P&lt;0.001). Our findings revealed that morphine can be recommended in acute pain management of opioid-dependent patients. In addition, emergency physicians should ask their patients about any drug dependence before selecting the appropriate drug for their acute pain management.

    BACKGROUND: Diabetes is a chronic disease and its control requires essential change in patients' life style. The aim of this study was survey of effects of educational intervention based on PRECEDE Model on self care behaviors and control in patients with type 2 diabetes. METHODS: This was a quasi-experimental study carried out in 78 patients with type 2 diabetes who have referred to Minoodasht clinic of diabetes. The educational program has been designed according to the PRECEDE Model. Prior to perform the educational intervention, the patients filled a questionnaire which was designed according to the structure of PRECEDE Model for type 2 diabetes patients. The diabetes education program was performed on three target groups (patients, their families and Health care personnel). After four weeks, the effects of the educational program have been evaluated through the same questionnaire. The findings were analyzed by SPSS version 16 and p-value less than 0.05 was taken as statistically significant. RESULTS: The mean age of participants was 49 years, 87.2 were married and 19.2 was illiterate. The rate of income of 44.9 was low. 66 had a family history of diabetes and 64 had been afflicted with diabetes more than 5 years. The Chi-square test showed a significant relationship between formation of a file in diabetes clinic and on-time presence to receive services and participation in the educational classes with the marital status variable. The results also showed that there is a significant relationship between observing food diet and job. The mean scores of knowledge, attitude, practice, reinforcing factors and enabling factors has increased after educational intervention. The Chi-square test shows a significant difference before and after of education intervention in stages of the model. CONCLUSION: The obtained results based on PRECEDE Model would support the positive effect of the educational intervention and its major elements (predisposing, enabling and reinforcing factors) on diabetes self-care behaviors
