Backgrounds and Phenol is one of the organic pollutants that is found in industrial effluents and is very toxic for human and environment. This study proposes the use of ostrich feathers as a natural source of active amino acids to remove phenol from aqueous solution. For this study، ostrich feather has been used as a synthetic adsorbent in removal of phenol in different doses 0. 2، 0. 3، 0. 5، 0. 7، 1، 1. 5 g/100 ml. Besides، the effects of changing contact time، pH، adsorbent dose and temperature has been determined. Description of adsorption Freundlich isotherm has also been accomplished and Excel software for analyzing the data was used. The result obtained revealed that by increasing the dosage of the sorbent from 0. 2 g to 0. 7 g the adsorption increases. The adsorption of phenol decreases by the increase of the pH value of the solution. In addition، it is observed that the contact time significantly affect the rate of phenol adsorption (70%) from solution. Generally، the adsorbent was applied successfully for treating industrial water samples and aqueous solution. ►Please cite this paper as: Manshouri M، Yazdanbakhsh AR، Daraei H. Determine the Optimum Parameters of Phenol Removal from Industrial Effluents by Using Ostrich Feathers.

Degenerative Joint disease (DJD) is the most common joint disease in human and the most cause of chronic disability in aging papulation in developed countries. Several studies explain that glocosamine Is better than plasebo and its efficacy is more in comparison with NSAID in knee osteoarthritic patient. Alendronate is prescribed for osteoprothic patients. The aim of this study was to compare the efficacy of adminstration of glocoseamine alone and in combination with alendronate in osteoarthritis of the knee. Subjects and A total of 130 patients of either sex with osteoarthritis were included in the study and randomised to receive glocoseamine alone (500mg TDS) and combination of Glocoseamine (500mg TDS) and alendronate (70mg weeky) for 12weeks. The patients were evaluated at 1; 3; 6 and 12weeks for efficacy. There was not statisticaly significant decrease in pain index (p>0. 05) but in total therapy the mean of pain is decreased. The stiffnes index in combination therapy was decreased (p<0. 05). The function of joint in combination therapy was improved after 12 weeks. The BMD after 12 weeks combination therapy was improved. Combination therapy of glocoseamine and alendronate was significant improvement of stiffness، function، BMD of osteoarthritis compared with glocoseamine alone but there was not statistically significant decreased in pain index. It can be concluded that the combination of glocoseamine with alendronate provide better and more rapid improvement in patients with osteoarthritis.

Intimate partner violence against women is a serious public health issue with recognizable direct health community consequences. This study indicated frequency of intimate partner abuse referred to Ahvaz health center and related factors with it. Subjects and After a preliminary study based on the frequency (P =65/7%، α =0/05)، 368 married women 15 to 55 year were selected with multi-stage sampling method The data were collected by Demoghrafic questionniar، Strauss-scale about abuse of women and conflict tactics scale was modified. For Reliability uesed content confidence. The validity is evalueted by currented test (r =% 78). The data obtain from scales were completed using an interview and analyzed using chi-squer test. Althogether، 63/2% of women had been exposed to various types of domestic violence by their partner، including psychology violence (58/8%)، physical violence (43/4%)، sexual violence (12/2%) and economic violence (34/2%). Statistically، there was a significant difference between abuse and the following factors: abuse and the following factors: women’s job’s (P=0/03)، economic condition (P=0/03)، educational level، married age and addiction (P<0/001)، monthly income (P<0/05)، married of husbend ‘s age (P=0/03)، numer of childern (P=0/006). However there was not statistically a signiicant difference between abuse and use child gender، lendhth of married، and smoking.. Conclustion: Regarding widespread prevalence of violence against women and related factors،it is recommended to implement national education program to control steress and help younger women to cope with problems in life.

The blood is one of the most important ways of transmission of nasocomial infections. Diseases such as HBV and HIV are most likely to be transmitted by anesthesia and monitoring equipment in operation room. The assessment of the frequency of blood contamination can be a useful determinant for the level of hazard and possibility of exposing patients and staff to source of infection. Subjects and This study was cross-sectional and performed in December 2009 and January 2010 on 140 samples of anesthesia and monitoring equipment in Jundishapur university hospital operation rooms. The equipments electrocardiograph cables، sphygmomanometer cuff، reservoir bag، pulseoxymeter probe، ventilator control pad، flow meter knobs and laryngoscope blade. Of all the samples 13. 57% were positive for visible blood and 32. 14% of samples were positive for occult blood. The most contaminated apparatus was electrocardiograph cables and the least contaminated was laryngoscope blade. The findings show high level of blood contamination on equipment and identify lack of compliance of established standards regarding disinfection. Recommendations are made to reduce the blood contamination hazards by planning standard for decontamination of equipment، periodic course of infection control practices for staff، using disposable instruments and purchasing well-designed anesthetic equipment.

Experimental and clinical evidence have established inflammatory processes as important contributors to atherosclerosis as well as to the vulnerability of an atherosclerotic lesion to rupture. The purpose of this study was to assess the relationship between plasma level of hs-CRP as noninvasive evidence of inflammation and its screening efficacy in diagnosis of atherosclerosis and extent of coronary vessels stenosis. Subjects and Our 87 cases selected from all patients who came with chief complaint of chest pain and had positive exercise treadmill test in paraclinic examination، and were referred for coronary angiography. Serum hs-CRP level of all these patient was cheked. Patients with cardiac dysfunction، rheumatic disease and infective disease were excluded from our study. The Patients were divided into two groups according to angiography group 1 comprised of 47 patients (24 men vs 23 women) with normal coronary angiography and group 2 comprised of 40 patients (28 men vs 12) with abnormal coronary angiography. The statistical analysis was performed with SPSS version 15. there was statistically a significant difference between age، sex and positive history of diabetic mellitus between two groups (p< 0. 05). Hs-CRP level was similar in both groups. There was no statistically significant correlation between Hs-CRP level and coronary angiography results. In this study، we found that there is not a clear relationship between plasma level of high sensitivity CRP with exercise induced ischemia، and also extent or the presence of coronary atherosclerosis.

Diabetes mellitus is a common metabolic disease in the world. The extract of Punica granatum flower (PGF) has been used in traditional medicine to decrease blood glucose and lipid. The aim of this study was to investigate the effect of this plant in high sucrose diet rats. Subjects and In this experimental study، 30 adult female Wistar rats weighing 150-170 (g) were used. After induced insulin resistance by sucrose 32% in drinking water for 6 weeks، the animals were randomly divided into 5 groups: sucrose induced، aqueous (400mg/kg) and hydro-alcoholic (300 and 500 mg/kg) extract of PGF. Control (normal) group was consumed only drinking water (n=6). 48 hours after the last interaperitonealinjection (IP)، blood was collected from heart، serum was separated and blood glucose، insulin، fasting insulin resistance index (FIRI)، lipid profiles، hepatic enzymes and blood pressure were determined. Blood pressure، insulin، glucose and FIRI in sucrose- induced group treated with extracts of PGF were significantly increased in comparison with the control group. Extracts of PGF decreased the lipid profile significantly; however،some hepatic enzymes were increased. The results of this study Showed that PGF extracts can increase blood pressure، glucose، insulin and FIRI in comparison with sucrose group. Thus، the PGF animals displayed characteristics typical of insulin resistance and it is suggested that the investigator could do more research on this plant.

The aim of this study is the assessment of quality of voice in patients who had radiotherapy to the neck in regards to parameters such as basic frequency، perturbation، and percent voiced، to investigate the effect of radiotherapy on patients'' quality of voice. Subjects and 34 patients with head and neck cancer that received radiation therapy as their only form of treatment underwent a voice analysis. The voice analysis consisted of an audio recording made to include three samples of a sustained phonation of the vowel/a/. Volume Unit Meter was monitored to peak at 0 during a practice count to 10. The best phonation of the three samples was played back for voice analyzer. Up to 9 seconds of the sustained vowel sound /a/ was analyzed for perturbation، percent of voicing and average fundamental frequency. This analysis was repeated 6 months following the completion of radiotherapy. The voice parameters of 15 patients with laryngeal tumors re analyzed separately from the 19 patients with non-laryngeal tumors. Patients with laryngeal tumors had 12% increase in the fundamental frequency، 14% improvement in perturbation and 52% improvement in percent voiced. Changes in percent voiced were statistically significant. Patients with non-laryngeal tumors had 42 % increase in the fundamental frequency compared to the baseline frequency before radiotherapy، 14% improvement in perturbation and 52% improvement in percent voiced. Patients with non larygeal head and neck tumors had 42% improvement in basic frequency compared to the baseline frequency before radiotherapy. Radiotherapy has significantly improved the voice quality of patients with early stage of laryngeal tumors.

The main goal of this research is assessment of the usage of Iranian National Medical Digital Library by faculty members of Ahvaz Jundishapur University of medical sciences. Subjects and

this research is descriptive-analytical and has been done as a survey study. Data collection has been done by means of the questionnaire. The society is 188 cases of faculty members of ajums that works in faculties. The results of this research have been calculated by from spss15 and diagrams have been drawn by excel and spss15.

National Medical Digital Library has a “high impact” on providing the faculty members with information requirements. The faculty members consider themselves as “medium” in familiarity with the information resources of National Digital Medical Libraty. ELSEVIER database has been recognized as the most frequently used database by faculty members. 35. 7% percent of faculty members have been trained to use information resources and 31. 8% of them have requested retraining. Of 64. 3% of faculty members who did not participate in training workshops، 57. 4% of them requested training workshops.

Traffic and low speed internet networks are the most important difficulties in accessing information resources. The most important reason of using information resources and satisfaction is up to date information resources. There is no meaningful difference between the use of information resources by faculty members and their sex degree and training workshop. However there is a meaningful difference between the use of information resources and academic degree of faculty members.

Tumors of salivary gland represent 2-3% of head and neck neoplasms and little is known about the underlying molecular mechanisms leading to tumorigenesis. P63 plays an essential role in epithelial development، stem cell identity and cellular differentiation and may act as an oncogene. The expression of P63 was analyzed to investigate the role of this marker in tumorigenesis of salivary gland neoplasms. Subjects and In this study، tissue specimens of 18 pleomorphic denoma (PA) and 9 mucoepidermoid carcinoma (MEC) were examined by immunohistochemistry for p63 expression. The percentage of positive neoplastic cells was calculated from a minimum of 1000 cells. In normal salivary gland and PA، P63 was expressed in myoepithelial and basal duct cells، whereas ductal and acinus cells were always negative. In MEC، intermediate and epidermoid cells expressed p63، in contrast to mucous cells. After using statistical test، the percentage of p63 positive cells in MEC was 84. 44% and in PA was 57. 83% (p<0. 05). p63 is expressed in the nuclei of normal salivary gland myoepithelial and basal cells. P63 expression is retained in the epidermoid cells of MEC and myoepithelial and basal cells of PA، which suggests a role of p63 in oncogenesis of these tumors.

Scientific and personal characteristics of teachers are important factors in Student-Teacher relationship. In this study the objective to determine the Factors that influence the relationship between teachers and students regarding the opinion of the students of Ahvaz University of Medical Sciences. Subjects and This study is descriptive-analytic. The population of the research Includes all students of Ahvaz University of medical sciences. The data was gathered by questionnaire. The criteria for assessment of questions were Likert scale. In this study، The effect of personal، ethical and professional characters of teachers was assessed as high by 63. 8 percent of students and very high by 23. 4 percent.. In between Of all these characters، “ethic” and “h umility” and also، “heartiness” of teachers have been the most effects regarding the students’ views. The effect of professional and scientific factors was assessed as inefctive by 18. 8 percent، as low by 1. 8، high by 48. 7، and very high by 30. 7 percent of the students. The effect of physical environment was considered as ineffective by 42. 4 percent، very low by 4. 7، low by 13. 8، high by 25. 3 and very high by 13. 8 percent of the students.. This study and other researches show that of different factors، ethical and personal characters of teacher are more effective in student- teacher Relationship.

pharyngo-cautaneus fistula is the most common complication (8. 7%-22%) after laryngectomy. Multiple factors such as radiotherapy are associated with complications after laryngectomy. Spite of the different treatments such as local، regional and advanced flaps، the ideal method for closing larg fistula of pharyngo- cautaneus is stiil a mater for debate. Subjects and In this investigation، 8 cases from 50 patients between 2001-2008 as prospective and 19 controls from 130 patients between 2001-2008 as retrospective underwent total laryngectomy for laryngeal cancer in Emam Khomeini hospital، Ahvaz، Iran، were chosen. All of the cases underwent antibiotic therapy، irrigation of wound with solution of clindamycin، acetic acid، dexamethasone and phenytoin and change of dressing 4 time in day. In the case and control groups، 8 (16%) and 19 (14%) patients were affected by pharyngo-cautaneus fistula. In the case group، six patients underwent radiotherapy before operation (12%). The mean time for beginning fistula formation and repair in cases and control group was 6. 5،9. 6 and 27،24 respectively. All of these cases responded well to this medical therapy method and 2 patients from control group needed surgery for fistula repair. In this study showed that the large fistula in patients with radiotherapy can also be cure with non-surgical treatment and special cares.

The concentration of ethanol measured in postmortem blood needs to be interpreted as to whether the person who had consumed alcohol has exceeded some threshold limit. However، interpreting postmortem BAC (Blood Alcohol Concentration) results and drawing correct conclusions about ante mortem levels is fraught with difficulties as under some circumstances alcohol might be produced after death by microbial activity. Subjects and In the case of ethanol، the blood samples should be taken from a femoral vein and whenever possible additional specimens، such as urine and vitreous humor (VH)، should also be obtained and sent for analysis to be able to have the best interpretation 167 Specimens of femoral vein blood and vitreous humor were analyzed. In this study، direct injection and gas-chromatographic techniques were employed to quantitate the ethanol concentrations. These two concentrations were then compared and the BAC/VHAC (Viterous Humor Alcohol Concentration) ratio was evaluated. Among these specimens، there were 142 cases in which we have found ethanol in blood but not in vitreous humor. Also we have found 2 cases by positive VHAC but negative BAC. The average blood ethanol concentration was 61. 5 mg/dLit while the average ethanol vitreous humor concentration was 127 mg/dLit. However، the ratio was measured as 0. 7. The similarity in the results of the post mortem cases reinforces the assertion that co analysis of vitreous humor and blood is important to interpret post mortem results.
