Abstract
Background and Aim: Today, many families either have pets or work in animal husbandry units. It is very important to investigate the mental outcomes of animal care and also to study their keepers’ personality traits. This study aims to perform a comparative examination of owners’ mental health and character specifications or those of animal husbandry units’ personnel.
Materials and Methods: In this descriptive study, about 500 people were selected through available sampling technique. They had contact with animals or worked in a husbandry unit in the suburbs of Tehran. After referring to the veterinary clinic of Tehran University, they were studied using a general health questionnaire and an international personality question bank. The collected data were analyzed using SPSS software as well as multivariate and follow-up tests.
Results: The results of the present study show that all general mental health sub-scales except for anxiety are different in these groups. However, no difference was observed regarding responsibility and extroversion. Meanwhile, the adaptability of dog owners was lower than that of sheep owners moreover, cattlemen were more irritable than sheep owners.
Conclusion : In sum, the mental health of pet owners of the present study is at a lower level compared to that of those in other countries. It seems that the difference is due to religious and cultural differences existing between the two.

Abstract
Background and Aim: Cream is a rich dairy product with the pH close to neutral and
limited preservation capability. Cream is suitable and rich for microbial
growth. In the past few decades, there was a great concern in contamination of
food products.
Salmonella and Yersinia species are two
important pathogens causing food poisoning and human gastroenteritis. The aim
of the present study is to investigate the quality of traditional cream for
bacterial contamination.
Materials and Methods: This is a cross-sectional study. In total, 100 unpasteurized
cream samples were collected from 5 regions in Tehran. The Salmonella was
enriched in Selenite-F broth, and Yersinia in
phosphate buffer in two weeks in cold condition according to CDC, and then were
inoculated in MacConky and CIN agar for 24 hours. The suspected colonies were
examined for phenotype and their identification was confirmed by API-20 E.
Results: In
general, 29% of tested cream samples were contaminated with at least one kind
of bacteria, 3% with Yersinia (1strain Y.enterocolitica, 1 Y.intermedia, 1
frederiksenii), and 2% with Salmonella paratyphi B. The other bacteria like
Escheichia coli, Enteobacter, klebsiella, and Citobacter were also isolated.
Five samples were contaminated with two kinds of bacteria.
Conclusion: The
results of this study indicate that more quality control should be applied on
the cream produced in the city of Tehran by health control office for food
products.

Abstract
Background and Aim: Along with the constant increase in world population
and consequently, the growing need to provide cellulose, as the most abundant
organic substance in nature to produce cellulose products, concerns regarding
the possible contamination of these products might cause skin, and genital and
urinary infections. The aim of this study is to determine the possible
microbial contamination of these products supplied in the city of Tehran.
Materials and
Methods: This is a descriptive study
on 200 samples of unexpired cellulose products including napkins, nappies,
sanitary napkin, and cardboard boxes to carry sweets. Fifty samples were obtained
in the city of Tehran during six months from September 2011 to February 2012.
Microbial contamination was investigated according to the procedure proposed by
the Institute of Standards and Industrial Research of Iran.
Results: The results obtained indicate that 18 samples (9%)
exceeded the level allowed for aerobic bacteria and molds in one gram of
specimens. Besides, 16 samples (8%) were contaminated with at least one of the
following bacteria: Streptococcus Group D, Staphylococcus aureus, Pseudomonas
aeruginosa and Escherichia coli. A total of 34 samples (17%) could not be
consumed. The least and the most contaminated products were sanitary napkins
(0.5%) and cardboard boxes to carry sweets (5%), respectively.
Conclusion: The presence of pathogenic bacteria in cellulose
products that could cause skin, and genital and urinary tract infections asks
for more control over such sanitary products.

Abstract
Background and Aim: Probiotics are useful bacteria which, after being
consumed, leave useful effects on human health. The present study was conducted to examine the
antimicrobial effect of Lactobacillus
paracasei on
pathogenic bacteria, especially on Staphylococcus aureus in the field of food microbiology. Materials and Methods: In this study, the effect of Lactobacillus paracasei isolated from
yoghurt (1×108 cfu/ml) on the
growth of Staphylococcus aureus (1×105 cfu/ml)
was assessed at two different temperatures of 25 °C and 35°C in TSB. Then, samples from cocultures and control
were pour plated in Baird Parker agar and MRS agar to compute the number of S.
aureus and Lactobacillus paracasei at 0, 24, 48, 72 hours after incubation.
Then, enterotoxin production was evaluated by ELIZA rida screen kit. The data
were investigated by ANOVA and K-square (chi-square) tests.
Results: It was found that compared to controls, Lactobacillus
paracasei inhibited the growth of Staphylococcus aureus and reduced the number
of S. aureus cells about 3 logs in 25°C and 2 logs in 35°C. The production of A, C, and E enterotoxins was
inhibited by S. aureus at a temperature of 25°C according to ELIZA rida screen test. The figure was
35°C for enterotoxins
E and A.
Conclusion: Probiotics can be used as a new approach for the
biocontrol of S. aureus without using antibiotics.

Materials and Methods: In this descriptive cross-sectional study, 250 students were selected randomly and their critical thinking disposition was assessed. "The Ricketts critical thinking disposition scale (2003)" consists of 33 multiple choice questions; the scale was used by the researcher to assess the critical thinking disposition. Finally, the data was analyzed by t-test and ANOVA using SPSS software.
Results: The mean of students’ critical thinking disposition was 3.54 which shows that this ability was on the average among students. Also, the t-test results showed that there was a difference between freshmen and seniors. The critical thinking disposition was compared between students in various fields; the results did not reveal a significant difference.
Conclusion: In spite of the high critical thinking disposition achieved by senior students and the similar guidance in different fields of study for enhancing the disposition, the variable is not at the ideal and expected level. Therefore, it is necessary to use certain materials and measures in educational planning so that the disposition level can get close to the ideal level.

Abstract
Background and Aim: On panoramic radiographs, sensitive organs, including the thyroid, are exposed to radiation. Thyroid cancer is one of the most common cancers in Iran. That is why, in this study the effective dose and risk of thyroid cancer were estimated on panoramic radiography.
Materials and Methods: Seventy GR200 thermoluminescence (TLD) dosimeters were used to estimate the absorbed dose of thyroid. The dosimeters were calibrated and placed on the patients’ necks during panoramic radiography. After dosimeters were read, the mean absorbed dose and effective thyroid dose were calculated in three groups with different radiation conditions. Lifetime Attributable Risk (LAR) of thyroid cancer was estimated using the model presented in the BEIR VII report. GraphPad Prism statistical software was used to analyze the data.
Results: The mean absorbed dose of thyroid lobes in groups M, L, XL (According to mandibular size) was estimated to be 0.116±0.01, 0.123±0.04 and 0.03±0.134 mg, respectively. The right thyroid lobe in group XL with absorption dose of 0.143±0.05 mg and the left lobe in group M with absorption dose of 0.106±0.03 mg had the highest and the lowest absorption doses, respectively. The difference between the absorbed doses of the right and left thyroid lobes in any of the three groups was not statistically significant. Thyroid absorption doses in these three groups were not statistically significant. The highest risk of thyroid cancer in the age range of 15-60 years was related to the age of 15, which was estimated to be 0.238 in women and 0.042 in men per 100,000 people.
Conclusion: In lower ages and among women, the risk of thyroid cancer is higher than that of men. Also, due to the impossibility of limiting thyroid radiation in panoramic radiography using lead thyroid collar that causes metal artifacts, we should reduce the number of panoramic radiographs as much as possible, especially at lower ages.
