Background and purpose: We can examine the language abilities of a person through five parameters of speech quality including speech fluency, speech complexity, speech exactness, speech rate and lexical accessibility. These parameters are examined by the secondary parameters including mean length of utterance (MLÜ), mean length of five long utterances, mean number of verb in sentence, mean number of bound clause in sentence and richness of vocabulary. We have examined four parameters except the speech exactness in normal Persian children of 4-5 years old in Semnan, Birjand and Tonekabon cities. These parameters were then compared between children.
Materials and methods : 90 children were selected nurseries through testing and they were divided into three groups including 30 subjects from. Âfter examining the children’s speech, they were analyzed and secondary parameters were determined. Finally we compared the results through statistical tests.
Results : Semnani children’s MLÜ of descriptive speech exceeds tonekaboni children. Semnani children’s mean length of five long utterances of free speech exceeds Birjandi children. Semnani children’s mean number of verb in sentence of free speech exceeds Birjandi children, Birjandi and Toneckaboni children’s mean number of bound clause in sentence of descriptive speech exceeds Semnani children. Birjandi children’ richness of vocabulary of free speech exceeds Semnani and Toneckaboni children. Birjandi children’s speech rate of free and descriptive speech exceeds Semnani and Toneckaboni children.
Çonclusion : Dialect contributes to speech quality parameters therefore we must consider them in assessment, diagnosis and treatment of language disorders in children with different dialects.

Background and purpose: The Common Coot (Fulica atra) is an abundant aquatic bird in North of Iran and is anticipated to be a good indicator for metal pollution on north wetlands of Iran. The aim of this study was to determining metals concentration in water, sediment samples and two organs of Common coot (liver and kidney). Materials and methods: This study was tested on water, sediment and 30 Common coot samples, in winter 2009. The water and sediment samples were respectively collected by Rotner bottle and Ekman grab within six sites of Gomishan and Khalij Gorgan wetland. The concentration of heavy metals in samples (Bird tissues, water and sediment) was measured by GF-AAS and Flame-AAS. Results: The data indicated that maximum heavy metals concentration in water belongs to lead (0.154 ± 0.02 ppm) and in sediment to Zn (2.04 ± 0.42 ppm). There was a significantly high correlation among heavy metals in water and sediment samples (P<0.01). The metals (Cd, Pb, Zn) level in both water and sediment samples was below standard level, whereas Cr concentration in water sample was almost higher. The highest concentrations of cadmium and lead found in liver (2.2 , 9.1 µg/g) and kidney (2.1, 8.9 µg/g) of Common coots, respectivly. Among the metals, the highest concentration in liver was Zn element (14.9 ± 7.24 ppm) and the lowest level in kidney belongs to Cr (0.76 ± 0.56 ppm). Moreover, the data pshowed no any significant difference in both liver and kidney organs of both sexes. Conclusion: The result indicated that lead concentration in kidney and liver tissues of Common coot was at exposure level and cadmium found below toxicity level.

Background and purpose: Solid waste leachate including different physical, chemical and biological pollutants is one of the most contaminated wastewater types. The limitations of conventional biological method for leachate treatment are the high energy consumption, nutrient requirement, sludge production, and cost. In this research, the efficiency of anaerobic baffled reactor modified by anaerobic filter (ABR-AF) was studied in solid waste leachate treatment located in Sari. Materials and methods: In this study, two glass reactors (six cells) were used. Each cell in upward section was equipped with a sampling port (and also a gas exit) and the volume of each reactor was 5.7 L. The initial cell was used for suspended solid settling and the last cell acted as an anaerobic filter in ABR-AF. The blank reactor characteristics were the same as the initial one except that it was without sludge and filter media. The interior temperature of the cells was adjusted by four electrical elements. After reaching the equilibrium, the leachate with different organic loading entered the reactor. Then, different parameters (COD, BOD5, TSS, o-phosphate, nitrate, ammonia, pH, etc.) were measured in different places of the reactors. All analyses were performed according to the “Standard Methods for the Examination of Water and Wastewater”. To analyze the data, analysis of variance and regression tests were performed in SPSS version 16. Results: The system efficiency for COD removal varied in the range of 39-96%. The maximum efficiency for COD removal was related to three days detention time and 10.72(Kg COD/m3.d) organic loading, while the minimum efficiency for it before the filter was related to one day detention time and 1.96 (Kg COD/m3.d) organic loading. The average efficiency for BOD5 removal varied from 39 to 58% and it ranged from 4 to 16% for o-phosphate removal. Conclusion: The ABR-AF system alone is not able to provide the effluent discharge requirement to surface and groundwater, but it can meet the needs of effluent discharge requirement to agricultural waterways.

Background and purpose: Helicobacter pylorus is a well-recognized cause of chronic active gastritis, peptic ulcer disease (PUD) and linked to the development of gastric adenocarcinoma. Heat shock protein (HSP) acts as molecular chaperons in the folding of newly synthesized proteins in cells and assist in the refolding of damaged proteins.The HSP70-2 gene has a pst1 site due to an A to G transition at the 1267 position and different genotypes of the HSP70-2 gene have been shown to be associated with a different level of HSP70 mRNA expression. The aim of this study was to investigate the association between polymorphism of the HSP70-2 gene and susceptibility to helicobacter pylori infection. Materials and methods: The studied population comprised of 100 subjects, attending the Endoscopy Center of Hafez Hospital in Shiraz, Iran. All the subjects underwent upper gastroscopy. RFLP (restriction fragment length polymorphism) analysis was performed for 1267G/A polymorphism of HSP70-2 gene in all the subjects. Results: After gastroscopy, 50 cases with H. pylori infection and 50 cases with normal gastric tissues were considered as the controls. In the normal subjects, the HSP70-2 genotype distribution was 20 AA (40%), 26 AG (52%), and 4 GG (8%). Meanwhile, the HSP70-2 genotype distribution in patients were 5 AA (10%), 43 AG (86%) and 2 GG (4%). Conclusion: The analysis showed that the AG genotype increased the risk of peptic ulcer (OR = 6.61, 95% CI = 2.21-19.76, P = 0.0007). The results of this study suggested that HSP70-2 polymorphism may be involved in susceptibility to helicobacter pylori infection.

Background and purpose: Gastric cancer is one of the most common gastrointestinal cancers in the world. Gastric cancer is the most common cancer in north of Iran. Interleukin-17F (IL-17F) is a pro-inflammatory cytokine expressed by a novel subset of CD4+ Th cells (Th-17), and it causes the occurrence and strengthening the inflammatory response. This study aimed to assess the association between IL-17F- A7488G polymorphism and potential susceptibility to gastric cancer. Materials and methods: A case-control study consisting of 161 gastric cancer patients with mean age 62.14 ± 12.6 and 171 healthy controls with mean age 58.93 ± 14.2 was conducted. Genomic DNA was extracted and genotypes of - A7488G polymorphism were assessed through polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: The frequency of G allele was higher in gastric cancer patients (12.1%) compared with the control group (9.15%), but these differences were not significant (P═0.22). In addition, the distribution of GG genotype was not significantly differed between the patients and the controls (4.3% vs. 1.8%, P=0.182). Furthermore, logistic regression analysis revealed no significant association between the presence of 7488G allele and clinical stages (P=0.28), tumor grade (P=0.36) and H. pylori infection (P=0.89). Conclusion: These results suggest that IL-17F A7488G polymorphism in the promoter of IL-17F gene is not directly assumed as a genetic risk factor in the predisposition to gastric cancer.

Background and purpose: Assessment of tooth length has an important role in success and failure of dental treatments. As yet periapical radiography has been used for the assessment of tooth length causing high x-ray exposure, long time and patient discomfort. Using panoramic radiography can resolve these problems. The major disadvantage of panoramic radiography is monotonous magnification. The aim of this study was to assess the relationship between real and panoramic tooth lengths. Materials and methods: In an analytical study, 89 teeth consisting 59 maxillary first premolars and 30 maxillary second premolars from patients referring to orthodontic clinics of babol were selected. According to universal numbering system the teeth were divided into four groups: T14, T24, T15, T25. Measurements of real and panoramic tooth length were accomplished by a digital caliper. Length linear regression model analysis was used for the prediction of tooth. Results: Real and panoramic tooth lengths and their magnification showed significant differences between two sexes (P< 0.05). For each gender regression models were produced: (male first premolar tooth length= 0.818X+3.017) (female first premolar tooth length= 0.852X+1.875) (male second premolar tooth length= 1.030X-2.028) (female second premolar tooth length= 1.020X-2.246). Conclusion: Using panoramic radiography for estimation of maxillary premolar real tooth length in studied machine is practical and reliable.

Background and purpose: Gastric cancer is one of the most common cancers in the world and Mazandaran province is known as one of the areas with high incidence of gastric cancer in Iran. This study examined the survival rates and factors affecting survival of patients with gastric cancer treated in Touba Clinic of Sari. Materials and methods: In this retrospective study the information of 430 patients with gastric cancer were studied. They were followed up for a 5-year period from November 2007 until December 2012. The overall survival rates were determined using nonparametric method of Kaplan - Meier and univariate analysis, and log rank test was used to determine the factors affecting the survival rates of the patients. Results: Among the patients 68.8% were male and 31.2% were female. The mean age of male patients was 65.98 years and in female it was 61.12 years. The mean and median survival rates of these patients were 27.82 months and 19 months, respectively. The survival rate of the studied population in one, two, three, four and five years were 0.64, 0.44, 0.34, 0.28 and 0.19, respectively. Univariate analysis identified age at diagnosis (p= 0.001), degree of differentiation of tumor (p= 0.031), metastasis of disease (p= 0.000), tumor stage (p= 0.000), type of treatment for the patient (p= 0.000), histopathology type (p= 0.013), and location (p= 0.009) as effective diagnostic factors. Conclusion: Five-year survival rate of patients with gastric cancer is low in Sari. Late referred and delayed diagnosis could be the reasons, therefore, early detection and screening methods are of great importance in improving the survival rate in these patients

Background and purpose: Pertussis is one of the communicable reasons of prolonged cough that children are being vaccinated in our country for prophylaxis. Despite high vaccine coverage the incidence of pertussis is still increasing. This study was done to investigate the prevalence of pertussis in children and its clinical manifestations before and after the beginning of vaccination age. Materials and methods: This descriptive-analytic study was performed in children with coughs for more than two weeks whom found with no reason for prolonged cough and were diagnosed with pertussis. The clinical records of the patients were assessed and the result of culture was studied. The data was then analyzed using chi square test in SPSS ver.17. Results: A total of 156 patients including 67 (42.9%) male and 89 (57.1%) female with the mean age of 15.8±1.9 enrolled in this study who had history of more than two weeks cough. Among the cases 137 (87.8%) patients had paroxysmal cough with an average of 6.9 days. Seven cases (7.8%) had positive cultures for pertussis of whom four aged under two months of old and three were older than two months of old. There was no significant difference in clinical manifestations of the two groups (less and more than two months). Conclusion: It is suggested to vaccinate mothers for immunization of children before the beginning of vaccination age. Also, to achieve a better immunization for children at the age of vaccination, using high potent acellular vaccines with fewer side effects are of great benefit.

Background and purpose: Development of arteriovenous fistulas (AVF) is one of the major advances in the management of patients undergoing hemodialysis. Patency rate of these fistulas and the factors influencing them is of great importance to reduce the costs and rate of repeated hospitalization. Materials and methods: In a five-year study 72 patients who had native AVF were followed for one year. Function time of each fistula, site, type of anastomosis, age, sex, history of diabetes, hypertension, temporary catheter for dialysis, and duration of renal failure (RF) were determined. Results: One- year patency rate of AVF was 80.6% which was found significantly lower among those aged more than 65 years, cases with history of RF more than 20 months, and among patients who had wrist fistulas (P=0.001, 0.002, 0.031, respectively). However, the patency rate was not affected by other factors. Conclusion: Because of high patency rate, native AVF is yet the best way of vascular access for repeated hemodialysis. To achieve an optimal outcome with AVF we recommend placing them preferentially in the upper arm in those older than 65 years of age and in patients with prolonged history of RF. In addition, patients with chronic RF must be selected for this operation earlier in the course of their disease.

Background and purpose: One of the most important of post coronary artery Angioplastycomplications is hemorrhage and hematoma. In our country initial hemostasis is done by hand pressure in puncture site and use of sand bag and absolute immobility for maintain hemostasis. Sand bag pressure and applied immobility lead to significant patient discomfort. In this regard and in order to achieve a solution for reducing complications after angioplasty the aim of this study is determine the effect of two methods of sand bags and air cushions on reducing complications after coronary artery angioplasty. Material and Methods: This quasi-experimental study was performed on 80 patients for elective angioplasty, based on inclusion and exclusion criteria were selected and randomly assigned to two groups of sandbag and the air cushion. Complications after angioplasty including low back pain, fatigue, and inguinal discomfort in both groups were evaluated during a 6 hours rest. Results: Regarding the severity of back pain, fatigue as well as discomfort in the groin immediately following the removal of the sheath no significant difference was reported in both groups. A significant difference was observed in sandbag group in later stages (P<0.001). It also revealed that this group had to receive more narcotics to relieve the pain (P=0.0025). There was no significant difference in the incidence of hematoma between the two groups (P=0.314). Conclusion: Regarding the findings of the study, it was revealed that applying air cushion to the femoral artery puncture site will lead to the possible position change in bed, no increase in hematoma and bleeding, significant reduction of back pain, patient comfort and also reduction in the prescription of analgesics.

Background and purpose: Biological monitoring for workers exposed to solvents includes complementary environmental monitoring which is useful in toxic chemical risk assessments. The aim of this study was environmental and biological monitoring of workers exposed to volatile organic compounds (VOCs) in petrochemical industry. Material and Methods: Air and urine samples were collected from 104 individuals working in petrochemical industry. NIOSH 2549 method was used to determine the concentrations of benzene, toluene, xylene isomers, phenol, and methyl ethyl ketone in breathing environment. In order to determine the concentration of urinary metabolites, urine samples were analyzed by high performance liquid chromatography and gas chromatography. Urinary creatinine level was measured by UV-VIS spectrophotometer. To analyze the data t-test and linear regression were performed in SPSS V.16. Results: The mean concentrations of benzene, toluene, O and m-xylene, P-xylene, phenol and methyl ethyl ketone in breath samples were 1.192, 1.300, 1.97, 1.290, 0.0116, and 2.243 ppm, respectively. The mean concentrations of urinary trans, t- MA, hippuric acid, 2, 3 and 4-methyl hippuric acid, and phenol were 1431 µgr/grCr, 0.3949, 0.4444, 0.1483 gr/grCr, and 0.5850mgr/grCr creatinine, respectively. Concentrations of urinary methyl ethyl ketone were 0.154 mgr/lit. There was a direct linear relationship between concentration of VOCs in the air and urinary metabolites (P>0.05). The results showed that increase in working hours per week resulted in increased level of urinary t, t- MA, methyl hippuric acid isomers and phenol (P>0.05). Conclusion: The mean concentration of benzene in breathing environment, urinary t, and t- MA was higher than the ACGIH's Threshold Limit Values (TLV) and Biological Exposure Indices (BEI) while the mean concentrations of other compounds were lower than TLV and BEI. We also found that smoking increased urinary excretion of all metabolites expect hippuric acid.

Background and purpose: One of the most common methods used to estimate the effects of explanatory variables on survival time, is Cox semi parametric model. However, under certain circumstances, accelerated failure time parametric models are superior to the Cox model. The purpose of this study was to assess the efficiency of parametric and semi-parametric models in survival analysis of patients with gastric cancer. Material and methods: In this retrospective study, we analyzed 249 medical records of patients attending Tooba clinic affiliated to Mazandaran University of Medical Sciences. We obtained information on the final status of patients viaphone calls.Parametric methods including Weibull, log-logistic and log-normal and semi-parametric Cox model was fitted on the data to identifythe factors reducing survival time Results: The results showed that patients with primary progress of disease, surgery as a treatment and patients without metastasis had higher survival rate than patientsin otherstages of disease and treatment (P<0.05). According to the value of Akaike Information Criterion (AIC) in univariate and multivariate analyses, lognormal model had best fitness in these data. However, parametric regression model had fitted better than Cox semiparametric regression. Conclusion: In this study lognormal model had highest fitness in our data. However, there were no significant differences between values of AIC of these models.According to the results, applying parametric model is suggested instead of semi parametric model if there is enough information about survival time and trend of variation.
