Background and Objectives: Toxoplasmosis is a most common parasitic infection in humans and animals, it has two acute and chronic phases that related to IgM and IgG, respectively. This prevalence is affected by different variables, so determination of the prevalence of serum IgG and IgM antibodies against Toxoplasma in terms of these variables like age, occupation and education level is so important.
Methods: This descriptive-analytic cross sectional study was done on 350 pregnant women referred to health - Therapeutic centers of Hamadan city.
After obtaining informed consent from volunteers, their serum samples were tested by IgG ELISA and IgM ELISA methods and their associations with age, occupation and education level variables were measured.
Results: From total of 350 pregnant women, 105 cases (%30) had anti Toxoplasma IgG, and 3 cases (%2.9) had anti-Toxoplasma IgM. Antibody titer of IgM with variable age, occupation and education level was not significant, but antibody titer of IgG with these variables was significant.
Conclusion: Given the significant association between the disease and age, occupation and education level in pregnant women, it should be provide the necessary training and knowledge about prevention and avoid of being infected with toxoplasmosis infection.

Background and Objectives: appendicitis is a common urgent surgical operation. Since early diagnosis and treatment of appendicitis is necessary and also some disease mimic its clinical manifestation and rate of negative appendectomy was high (%30-15), so surgeons were trying to increase the accuracy of diagnosis of appendicitis by using laboratory facilities. The main aim of this study was to investigation of sensitivity and specificity CRP in the diagnosis of acute appendicitis and compares it with routine laboratory tests such as leukocyte count and neutrophil count.
Methods: In this descriptive - analytical study, blood samples of 191 patients with diagnosis of acute appendicitis that underwent appendectomy at the Besat hospital, were used to measuring of CRP. The surgical specimens were reviewed by pathologists and pathologic findings were considered as gold standard. Then by using of the results of pathology tests, sensitivity, specificity and positive and negative predictive value of CRP, WBC and neutrophils were measured. Data were analyzed by SPSS14.0 software and t test and chi square test.
Results: about 74 percent of the patients were male and 25.7% were female and the mean age was 26 ±3.4 years. The most common symptom, sign and pathologic stage of patients were loss of appetite (95.2%), local tenderness (95.8%) and Acute suppurative 64.9%. about thirteen percent of patients had normal appendectomies that consist of 35% of women and 6% of men appendectomy. The sensitivity and specificity of CRP, WBC and neutrophils respectively were: 93.3%, 50%, 84.8%, 61.5%, 98.1% and 19.2%.
Conclusion: According to the results, the CRP test at diagnosis and in finding of negative appendectomy has high value, but was not reliable as an exclusive test. Therefore, the use of CRP as a paraclinical criterion along with other criteria of Alvarado scoring system can be very useful in diagnosis of appendicitis.

Background and Objectives: Advanced phonological skills are important for the acquisition of reading skills. Children with hearing impairment have reading skills are weaker than others because of auditory inputs and due to the defect in phonological skills. The use of hearing aids and cochlear implants help to collect information on people who are hard of hearing.
Methods: This descriptive - analytic study was done on 12 children with cochlear implant and 12 children with hearing aids that were selected from second grades students of Tehran primary schools. Children's phonological performance was assessed by phonological subtests of Nama reading test and the data were analyzed using version 16.0 of SPSS.
Results: The results showed that the means of scores of children with cochlear implants in Rhyme task were significantly greater than the children with hearing aids (P=0.034). But in means of scores of Phone deletion and Non-word reading tasks were not significant different between two groups (P=0.919, P=0.670).
Conclusion: Cochlear implant with accessibility auditory inputs can facilitated the acquisition of phonological awareness skills in hearing loss children. But whereas the other language inputs such as sight and touch input helped to developing these skills, children with hearing aids too also can acquisition these skills.

Background and Objectives: fluoride in low concentration is essential for human but in high concentration is very hazardous for human health. The efficacy of Snail Shell (SS) was investigated in this research work as an adsorbent for the elimination of fluoride from aqueous.
Methods: in this experimental study, the capability of SS to adsorb fluoride ions was conducted using a series of batch tests in a shaker-incubator instrument. For each batch run, 100 mL of solution containing a known initial concentration of Fluoride and with the preferred level of pH was shacked. The effects of selected parameters such as pH (3-11), reaction time (5–60 min) cyanide concentrations (5-10 mg/L) and the adsorbent dosage (0.25–2.5g/L) were investigated on the removal fluoride as a target contaminate. Chemical composition SS were analyzed using a Philips model XL30- scanning electron microscope (SEM) with energy-dispersive X-ray microanalysis (EDX). The concentration of Fluoride in solution before and after treatment was determined using the HACH method.
Results: Analysis of the SS component using the EDX technique showed that the main part of it consisted of calcium and its other components were magnesium, aluminum and silicate. The experimental data showed that the maximum fluoride removal occurred at pH of 7, adsorbent dose (0.5 g/L) and 30 min contact time and 5 mg/lit initial concentration. The kinetic evaluation indicated that the pseudo-second-order kinetic had the best fit to the experimental results predicting a chemisorption process. The equilibrium adsorption of fluoride onto SS was well represented by the Langmuir equation.
Conclusion: As a result, SS was revealed as a very efficient and low-cost adsorbent and a promising option for removing fluoride from industrial wastewaters.
