- چکیده انگلیسی: Background: Early Childhood Caries (ECC) in the earliest stage is preventable. The studies indicate oral bacteria play an important role in pathogenesis of dental caries. According to high prevalence of ECC, alternative therapies should be explored in order to reduce the occurrence of it. Aim: This study aims to assess the effectiveness of a product containing Povidone Iodine 10% and Sodium Fluoride 0.2% as a supplementary intervention for preventing ECC.Materials and Methods: Thirty-seven children aged 4 to 6 year-old were recruited. Maxillary incisors on each side of the mouth were selected either as a test or control group. Early caries detection examinations were conducted using International Caries Detection and Assessment System (ICDAS) clinically and photographically. In a double-blind, placebo-controlled clinical study, a product containing a mixture of Povidone Iodine 10% and Sodium Fluoride 0.2% was applied to the designated incisors of the test group participants. This application was performed every week for a 3-month. The control group participants received a placebo mixture during the same time interval. The caries detection examinations were conducted again after 6 months and the results were compared. The data was analyzed with SPSS V.18, using McNemar test.Results: The incidence of carious lesions increased for the control group while it decreased in the test group (P<0.05(

- چکیده انگلیسی: Introduction: This study investigated the sealing ability of three different adhesives in primary bovine teeth. Methods: Facial and lingual class V cavities were prepared half in enamel and half in cementum, in 48 bovine primary mandibular incisors and randomly divided into three groups and each group divided to two subgroups. The tested adhesives were XPBond (XP), ClearfilS3 Bond (S3), and Xeno III (XE). All cavities were restored with composite and light cured. After 24 hours storage in 37°C distilled water and polishing, teeth were thermocycled and sealed with nail varnish. Then, they were stored in 2% methylene blue and dye penetration was evaluated under a stereomicroscope. Results: No significant differences were recorded in the microleakage value between three adhesives in enamel and dentin margins (p>0.0.5) before and after thermocycling. The lowest microleakage value was obtained in XE followed by XP and S3. Conclusion: There were not any differences between adhesives in enamel and dentin margins of class V cavities on primary bovine teeth.

- چکیده انگلیسی: BACKGROUND: Microbiological and chemical qualities of
milk are among the most important issues in public health.
OBJECTIVES:Although there are a few published studies which
have been conducted in south east of Iran this study was
performed to investigate quality of raw milk delivered to a dairy
industry company Kerman Province. METHODS:Atotal of 109
raw milk samples were collected at the time of delivering to the
company. All the samples were transferred to the food lab of
Veterinary School for total counting and psychotropic and
Staphylococcus aureus counting. The chemical contents,
residues of microbial inhibitors and Beta Lactam antibiotics
residues were evaluated by Lactostar, Copan kit and Beta star
test, respectively, and somatic cells were counted by a cell
counter. RESULTS: Based on the comparison with national
standard criteria, only 26 out of 109 samples (23.8; 95% CI: 16.2-
33.0) were at standard limits in terms of all the factors. Alarge
number of out-of-standard sample (50 out of 83), were in contrast
with the defined criterion due to low protein. CONCLUSIONS:
Classification of the samples based on all the defined criteria
without considering protein content showed that the main
problem of the milk was its low protein percent.- انتشار مقاله: 13-06-1392

- چکیده انگلیسی: Tramadol is a synthetic, centrally acting opioid analgesic that has the best analgesic efficacy without excessive sedation and significant side effects in the postoperative pain relief in dogs. OBJECTIVES: In this study, hematological and biochemical changes due to short usage of tramadol were assessed in clinically healthy dogs. METHODS: For this purpose, eighteen male mongrel dogs aged 14 to 22 months were used in three equal groups. In the first and second groups respectively (2 and 5 mg/kg) intramuscular tramadol and in control group distillate water was given once a day for five consecutive days. Complete cell blood count (CBC) and biochemical evaluation were done to measure aspartate amino-transferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), creatinin (Cr), and blood urea nitrogen (BUN) levels, before the intervention (day 0) and on days 6 and 13, post-treatment. RESULTS: Thirteen days post treatment, Red blood cell (RBC) and white blood cell (WBC) count and ALT, AST, ALP, Cr, BUN and packed cell volume (PCV) level was measured as 6.75±0.03, 3.86±0.13, 40.00±7.98, 43.67±8.62, 57.00±17.03, 0.90±0.27, 25.00±5.48 and 40.13±2.88 respect-ively which showed that short-term injection of even high doses of tramadol creates no significant change on hematological, liver, and kidney parameters in dogs. CONCLUSIONS: The present study suggests that tramadol could be a safe postoperative analgesic for control of acute pain in dogs referred for routine surgical procedures.

- چکیده:
- چکیده انگلیسی: Objective- Locomotor disorders are prevalent health problems in dairy herds that negatively affect milk production, reproduction performance and animal welfare. The ultimate cost of locomotor disorders in dairy cattle is substantially greater than treatment costs alone. As limited information is available on incidence of feet and leg disorders in Iran, the objective of this study was to determine cumulative incidence of locomotor disorders in dairy herds of Tehran province. Design- Historical cohort study Study population and procedures- Totally, 10506 Holstein cows, from 32 Iranian dairy herds, which calved from March 2007 to March 2008, were followed until the next calving or culling and cumulative incidence of locomotor disorders was calculated based on registered data. Results- Cumulative incidence of locomotor disorders in the studied cows was 23.2% (95% CI: 22.4- 23.9). This index was 20.0% (18.7-21.2), 19.6% (18.2- 21.0), 29.3% (27.1-31.5), 29.3% (27.1-31.5), 35.6% (31.6-49.3) and 23.8% (19.2-28.4) in the first to sixth and more than sixth lactation, respectively. This showed, locomotor problems are important issue in this area. Moreover, with increasing parities cumulative incidence of locomotor disorders increased; this increase could be due to weight gain, increased milk production and culling susceptible animals to these health disorders before sixth lactation. Conclusion and Clinical Relevance- Our findings confirm the results of previous studies that dairy herd-health programs should emphasize the control of feet and leg disorders.

- چکیده:
- چکیده انگلیسی: Background: Explaining the risk factors of waterpipe smoking (WS) is very necessary in prevention programs. The aim of this study was determining the risk factors and the prevalence of WS in adolescents based on the social cognitive theory (SCT).
Materials and Methods: This cross-sectional study was conducted among urban adolescents in two provinces located in the South East of Iran. We recruited 1,218 adolescents (girls=595 and boys=623) through multistage sampling during the period October 2017 to February 2018. The data collection tool was a self-administered standardized questionnaire that included basic baseline characteristics, SCT constructs items and questions about WS behavior in the participants. The data were analysed using SPSS software version 22.0.
Results
The ever use prevalence of WS in boys was 43.8% (n= 264), and in girls 27% (n=160). WS in family member (OR=1.87, CI: 1.32-2.63; p<0.001) and intimate friends (OR=2.34, CI: 1.70- 2.26; p<0.001) were the most important risk factors for adolescents. In the relation of WS with constructs of SCT: outcome expectations (OR=0.64, 95% CI: 0.50-0.84; p<0.001), outcome expectancy, (OR=0.65, 95% CI: 0.55-0.85; p=0.002) self-efficacy, (OR=0.30, 95% CI: 0.23- 0.41; p<0.001), and situational perception (OR=0.63, 95% CI: 0.47- 0.84: p=0.002) were the most important and related factors of WS. Boys were 1.92 times (OR: 1.06 – 2.43; p<0.001) more exposed to water-pipe smoking than girls.
Conclusion
The prevalence of WS was notable in students especially in boys. Peer group and family are important risk factors for tendency toward WS in adolescence. Also, lower score in SCT constructs such as knowledge, self-efficacy and situational perception in adolescents are important risk factors for WS in participants.- انتشار مقاله: 04-03-1398

- چکیده: Type D personality is predictive of adverse clinical outcome and psychological distress in cardiac patients. The mechanisms by which type D personality influences health are largely unknown. The aim of this study is to investigate the relationship between type D personality and the health locus of control. A sample of 588 students (370 females and 218 males)were selected, according to the cluster random sampling method, from the students of Tabriz University and were asked to complete a questionnaire about type D personality and Multidimensional Health Locus of Control. Research data were analyzed by statistical methods of Pearson correlation and stepwise regression analyses. The results showed that, through dimensions of Health Locus of Control, only the relationship between negative affect and social inhibition with health locus of control of powerful others were positive and statistically significant. Also, regression analysis showed that components, such as negative affect and social inhibition were good predictors for health locus of control of powerful others. Based on these findings, we conclude that people with type D personality have high health locus of control of powerful others; and both dimensions, i.e., negative affect and social inhibition, are correlated with high powerful others’ health locus of control.
