Chest X ray is the first choice for the investigation of cardiovascular and respiratory disease. Radiographer technologists are responsible for managing the radiation exposure to patients and providing adequate image quality according to the ALARA (As Low as Radiation Achievable) concept. The knowledge and skills of radiographers in performing chest radiography helps to improve the diagnosis of diseases. The aim of this study was to assess the knowledge and skills of Radiographers on digital chest radiography in medical imaging departments.  

A descriptive cross-sectional study was carried out on 65 of radiographers of Yasuj teaching hospitals, which were selected by the census sampling method. The knowledge was measured by the researcher- made questionnaire, and the checklist was used for measuring the skills of the radiographers. 390 digital chest radiographs were assessed during and after each procedure. Each radiography was analyzed by two expert radiologists and researchers according to the checklist, and the knowledge was analyzed with SPSS software version 21.

The mean values of the radiographers’ knowledge and skills were 85.48±6.48 and 78.79±8.99 (out of 100), respectively. 5.38% of digital chest radiography (21 of 390) led to repetition. 

Although the awareness and performance of the radiographers in the present study are appropriate, radiographers should be properly trained on digital chest radiography for reducing the patient radiation dose and improve image quality and radiological interpretation.

The numerous health effects of acorn are well documented. Acorn tree is abundant in many parts of Iran and is usually wasted or used as animal feed. With the aim of increasing food application of acorn، in this research، different levels of acorn flour (0، 10، 30، 40 and 50%، w/w، flour basis) were replaced with wheat flour in the production of Barbari bread. The farinograph results showed that with increasing the level of acorn flour، water absorption of the dough and dough softening decreased while dough stability time increased. Increasing the oat flour level reduced dough and bread final volume، increased the density، darkness and hardness of the bread. Determination of the crust color and crumb texture during three days of bread storage showed that the staling of the bread increased as the level of acorn flour increased. Inclusion of more than 30% acorn flour had negative effects on sensory characteristics of the bread. In total، to produce acorn Barbari bread، inclusion of less than 30% acorn flour is suggested.

Sometimes, sensory disorders occur without any organic etiology which this entity could make problem in diagnose and treatment. Therefore, the aim of this present study was to evaluate the psychiatric treatment effects on unexplained oral and maxillofacial sensory disorders.

In this experimental study, 20 patients with diagnosis of unexplained oral and maxillofacial sensory disorders whit out any organic origin were examined. The severity of symptoms was documented based on a 0-5 numerical scale by patients. The patients were referred to the psychologist for their problems. All subjects were controlled per two weeks for about 6 months and in each follow up their severity of symptoms were detected. The mean of severity of sensory disorders was compare before and after treatment by t- test.

In this study, there was a positive correlation between psychiatric treatment and increasing in severity of patient’s symptoms. The mean of severity of sensory disorders before treatment was 4 unit and after that reached to 1.1 unit. The rate of therapeutic effect was higher in men than women. Also, the rate of response to the treatment in patients with involutional melancholia was better than patients with other psychological disorders.

The results of this study showed, that severity of unexplained oral and maxillofacial sensory disorders decreased after psychiatric treatments.

Backgrounds and

Total and Fecal coliforms (TC and FC), heterotrophic plate count (HPC), were counted by microbiological method and E.coli O157:H7 were detected through immunological and Real time PCRmethods inwater intake and all of units of Isfahanwater treatment plant (IWTP).

The microbial profile including TC, FC, and HPC, were monitored and turbidity and total organic carbon were analyzed in 8 locations of water intake, and unit operation and processes of IWTP, including, inlet, sedimentation, ozonation, and filtration and finished water. Immunological method through anti-serum kits and molecular method of RT-PCR were used to detect E.coli O157:H7 in the 8 locations and also the sludge of the sedimentation basin and filters backwash water of IWTP.

Survival of E.coli O157:H7 in sludge sample of sedimentation basin was indicated by formation of agglutination particles in immunological method and through indicator probes in the RT-PCR method. However, E.coli O157:H7 was not detected in water samples of other units of IWTP. The removal percent of TC, FC, and HPC were: 59.5, 49, and 54.8 % in sedimentation basin; 66, 45.8, and 57 % in ozonation;: 98.8, 98, and 78.8 in the filtration; and 96, 100, 91% in disinfection, respectively.

This study approved the existence of the pathogenic coliform, E.coli O157:H7 in thesludge of sedimentation basin. Absent of E.coli O157:H7 in the finished water indicates that the existing units of IWTP could eliminate these pathogenic bacteria, before reaching the final units of the plant, including the filters and disinfection.

In order to accelerate forcing, reduce the production period and to extend the vase life of Iris hollandica cv. ‘Blue Magic’ cut flowers, an experiment was performed in the research glasshouse of the Faculty of Agricultural Sciences, University of Guilan, Rasht, Iran, in 2007. The experiment was carried out as factorial based on completely randomized design with three replications. Factors were temperature (5, 10 and 15C) and gibberellic acid (0, 300 and 600mg/l). The concentration of 600mg/l gibberellic acid at 5C accelerated sprourting and flower appearance and increased stem length, vase life of cut flowers and percentage of total soluble solid of petals as compared to other treatments. Furthermore, treating cut flowers with 600 mg/l gibberellic acid significantly increased the anthocyanin of petals and chlorophyll content of leaves. Also, reducing the temperature to 5ºC significantly increased the anthocyanin of petals.

Eczema is a common inflammatory skin disease. Although history and physical examination are important in diagnosis of allergen, because of extent of environmental allergens, those are not simply recognized. The objective of this study was to determine allergens in patients with contact or atopic dermatitis referred to Razi hospital.

This descriptive, cross sectional study was performed on patients with contact or atopic dermatitis in 2003-2004 with European Standard Series patch test containing 24 allergens.

In this study 223 patients were tested with a mean age of 31 years (SD=12). The most common involved location was hand (59%). The most common allergens were nickel sulphate (23/2%), cobalt (11/4%) and thiuram (8/3%).

Nickel sulphate was the most common contact allergen in this study.
