Postoperative pain following root canal therapy in of concern for the patient and dentist. Despite the fact that the pain relief afforded by endodontic treatment is effective، it is rarely immediate and complete. The purpose of this study was to compare the efficacy of amitriptyline with ibuprofen in controlling of post-endodontic pain. This randomized double-blind placebo controlled clinical trial included 75 patients with symptomatic vital molar which presented with moderate to severe endodontic pain. Patients were randomly allocated in one of 3 groups to receive uniform capsules containing placebo، ibuprofen 600mg or amitriptyline 50mg as single dose 90 min before root canal treatment. Pain intensity was recorded in Visual Analogue Scale (VAS) chart in defined times before، during and after treatment by patients. Data was statistically analyzed by Repeated Measures ANOVA and Tukey test. Statistically significant differences in mean pain score was seen between ibuprofen and amitriptyline groups with placebo group during، and 12، 18، 24، 36، 48 hours after treatment; but the difference was not significant at 6، 60، 72 hours after treatment. The difference between amitriptyline group and ibuprofen group was not statistically significant at any time. The results showed that amitriptyline administration is as effective as ibuprofen in management of post-endodontic pain in patients presented with moderate to severe pain.

Recently، as human population has been increased quickly، water problems and its distribution have affected water storage in the Third World، especially in arid and semi-arid areas like Sistan. The aim of this study was to investigate water quality of three reservoirs of Chah- Nimeh during different seasons of 1390. This research was done as descriptive-cross sectional for one year on three reservoirs. For water sampling، three stations at inlet، middle and outlet of each reservoir were chosen. The sampling was performed during four seasons of 1390، at the water depths of 10، 20 and 30 cm each at three replicates so that، totally، 324 water samples were taken. Then different water qualities including EC، pH، TDS، DO، TSS، turbidity، salinity، hardness، nitrate، nitrite، phosphate، temperature، coliform، BOD and COD were measured at laboratory. Finally، measured water qualities were assessed according to the universal standards. The results of sampling were compared with the relevant standards of Iran، FAO، WQI and Wilcox regarding to different applications in drinking and agriculture sections. Assessment of the WQI showed that for the studied reservoirs this index was 54، 59 and 58، respectively، indicating moderate drinking water quality. Also، based on the Wilcox index، water quality classified as C2S1 and C3S1. The results also indicated that all the measured parameters except pH، Mg، NO3، Na، BOD، COD and DO showed significant changes (p<0. 05) with season. Also، coliform، Na، turbidity and TSS showed significant differences (p<0. 05) among the studied reservoirs، whereas most of the water quality parameters were in a similar range among the three reservoir. Also، the average coliform in reservoir No. 2 was higher than that of the other two reservoirs which was attributed to the pollution of adjacent area. Assessment of Wilcox Diagram and WQI index showed that all the three reservoirs were classified in moderate condition for agricultural and drinking applications.

Evacuation and curettage is a widely used method for management of first trimester abortion. This study was conducted to compare the effect of oral misoprostol on pain scores، duration and amount of vaginal bleeding and endometrial thickness following surgical evacuation for first trimester abortion. This was a clinical trial on 120 patients who underwent surgical evacuation for first trimester abortion. The patients were randomized in two groups to receive either 200 microgram of oral misoprostol immediately and 6 hours after evacuation or no misoprostol. The two groups، were compared for pain severity 6 and 24 hours and 10 days after operation. Duration and amount of bleeding and endometrial thickness were assessed 10 days after surgery. The mean duration of vaginal bleeding was 3. 5 ± 1. 5 days in observation group، which was shortened as compared with 5. 8 ±2. 3 days in control group (P <0. 001). Amount of vaginal bleeding was reduced (5. 7 ± 1. 8 vs. 8. 6 ± 2. 1، P < 0. 001). Endometrial thickness 10 days after evacuation was less (5. 2 ± 1. 3 vs. 7. 1 ± 1. 6، P < 0. 001). But significant difference was not seen inpain scores in two groups. 200 microgram oral misoprostol immediately and 6 hours after surgical evacuation for first trimester abortion is effective in reducing duration and amount of vaginal bleeding and endometrial thickness.

Organizational justice has shown the perception of fairness and equality in the workplace by staff. It seems that organizational justice related with mental health. Given that studies in this field are scarce، this study is trying to examine the relationship between perception of organizational justice and mental health by staff in their work environment. Population of this study was the workers of Jahad-e Keshavari of Zahedan city (500)، that 133of them filled the Questionnaires (GHQ and OGQ). (OGQ)، were tested organizational justice in four dimensions (distributive justice، procedural justice، interpersonal justice and informational justice)، and (GHQ) were tested general health in four dimensions (physical symptoms، anxiety and Impaired Sleep Symptoms، social symptoms and depression symptoms). The data were analyzed by SPSS and Pearson correlation tests. The obtained results indicate a significant relationship between organizational justice، distributive justice، procedural justice، interpersonal justice and informational justice with mental health staff، that the relationship between perceptions of organizational justice and informational justice whit mental health at 99% confidence level and the relationship between distributive justice، procedural justice، interpersonal justice with mental health at 95% confidence level are significant. Also the strongest relationship is between perceptions of organizational justice and mental health. According to the research findings، the organizational justice dimensions were inversely and significantly associated with mental health. So، in order to have a healthy human resource، especially in terms of mental health، to Create the conditions in which human resources understand high equity in their organization، is necessary، because the lack of justice perception by human resource and thereby lower mental health is a problem that Regardless of organizational authority، can cause damage to a person or organization.

Immunohematological reactions to stressful situations have been interested of many investigators. The aim of this study was to investigate the effect of an intense anaerobic workout session on some parameters of athletes. In this analytic descreptive cross-sectional study، 20 professional athletes in volleyball field with mean age 5 ± 25 years were invited purposefully to study. In this study، 30 second Wingate test was used to assess anaerobic power. Samples of peripheral blood before، immediately after and two hours after exercise were collected and levels immunohematological indices were determined. The results of this study showed that immunohematological cells such as leukocytes، lymphocytes، neutrophils، erythrocytes and platelets counts before، after and two hours after practice، have changed significantly (P <0. 01). Results showed that one session of intense anaerobic exercise has significant effect on immunohematological indices of athletes.

Intestinal parasitic infections are amongst the most common infections worldwide. Epidemiological research carried out in different countries has shown that the social and economical situation of the individual is an important cause، due to the importance of epidemiological studies as first pace to identify and control the variety ofparasitical contaminations as well as lack of exact statistical information in this case، it is essential to be done among person asking for health card. This is a cross sectional study done using simple sampling from 210 persons that came to take health care in central laboratory in Zabol city. Data were collected by means of questionnaire consisting of information such as age، sex and job. Stool specimens were examined microscopically for the presence of parasite eggs، cysts and trophozoites using direct and formalin-ether concentration methods. The results showed that Incidence was 25/4%. Infection rate in men 25/5%and womens it wa 24/6%. protozoic Infection were Giardia (56/6%)، Enthamoeba Coli (28/30%)، Enthamoeba histolitica (1/89%) and helminth in infections were Hymenolips nana (1/89%)، Ascaris (9/43%)، Teania (1/89%). The was no significan differene incidence and sex، gob. To reduce the pollution in the maple، where Three months، a high stool method like formaldehyde concentration، Monitor and enforce strict health regulations by health experts، Direct instruction in social hygiene and parasite transmission mode of education is proposed.

Toxoplasmosis is a zoonosis with prevalent geographic distribution. The parasite can stay alive in citrated blood for 50 days at 4 0C. On the other hand، Epstein-Barr Virus (EBV) is a gamma-herpesvirus and transmission of EBV through transfusion of blood products and Platelet-rich plasm has been reported. Screening for Toxoplasma and EBV is not mandatory in Iran blood banks. The aim of this consideration was to determine the frequency of antibody against Toxoplasma and EBV in blood donors referred to Gonabad Blood Transfusion Organization (East of Iran). A total of 300 serum samples were collected in 2011 from healthy voluntary blood donors who have referred to Gonabad Blood Transfusion Organization. After bloodletting and parting of serum، ELISA test was performed for all individuals. Results were analyzed by SPSS 16 software. of 300pateints studied، 62 (20. 7%) were female and 238 (79. 3%) were male. Mean age was 34 years old. Fifty-five (18. 3%) donors tested seropositive for anti-T. gondii antibodies; 48 (16%) donors were positive for only IgG، 5 (1. 6%) were positive for both IgM and IgG and 2 (0. 6%) were positive for only IgM anti-T. gondii antibodies. Thus the prevalence of IgG and IgM anti T. gondii antibodies was 17. 7% and 2. 3% respectively. Positive persons for IgM were 2 first-time blood donors، 1 sporadic donor and 4 regular donors. Forty six percent were positive for VCA- IgG Epstein-Barr virus antibody. The seropositivity rates for females and males were found as 48. 4 % and 46. 3%، respectively. Positive persons were 36 first-time blood donors، 34 sporadic donors and 69 regular donors. Our study showed T. gondii infection in 2/3% of voluntary donors that revealed significance of screening this antibody especially in regular donors. About EBV the results of this study confirmed lower distribution pattern to compare those reported in other studies.
