Abstract Background and objectives: some parasites especially Enterobius vermicularis and helminthes are the leading factor causing appendicitis. We did this study to determine the prevalence of infection with Enterobius vermicularis among excised appendices in Necoii hospital of Qom, Iran (2005-2006). Material and Methods: In this Cross-sectional Retrospective study, we referred to pathology district archive of Necoii hospital of Qom to collect the demographic data of 3420 appendectomy patients including gender, age and infection to Enterobius vermicularis. These patients had been undertaken appendectomy from March 2005 to March 2006. After confirm of infection, all patients demographic data and histopathological results were analyzed by using Chi-square test in SPSS version 11.5 software. Results: of 3420 appendices, 17 cases (0.5%) are infected with Enterobius Vermicularis. Thirteen of them (76.5%) are female and four (23.5%) male. also 15 of infected appendices (88.2%) don’t show any pathological changes and two cases (11.8%) have appendicitis. The highest infection rate is observed in 6-10 (41.1%) and 11-15 (35.3%) age groups. Conclusion: The results show that Enterobius vermicularis does not play a role in causing appendicitis, and its presence in excised appendix can not be a good reason for being the cause of appendicitis.

Abstract
ABSTRACT
Background and Objective: Staphylococcus aureus is the most common and important infectious agent. This bacterium can enter the bloodstream and cause some complications in the intensive care unit (ICU).This organism can frequently be found in the nose and transmitted by the carriers. This study aimed to determine the efficiency of eradicating S. aureus from the nose of ICU personnel in reducing the risk of S. aureus infections in the Panje Azar Hospital in Gorgan, Iran.
Methods: Sampling was done using sterile swabs collected from the anterior nasal passages.All samples containing Gram-positive cocci were sent to the laboratory of Faculty of Medicine for identification and evaluation of methicillin resistance. All S. aureus nasal carriers were treated with mupirocin ointment b.d for 5 days. The Samples were cultured again after five weeks to evaluate the eradication of S. auerus from the nose of subjects.
Results: Overall, seven ICU personnel (11.7%) were S. aureus carriers. Two isolates (3.3%) were found as methicillin resistant using both methods of disc diffusion and PCR. The frequency distribution of positive cases indicated a significant difference in terms of work experience (P = 0.012).
Conclusion: The findings show that treatment of carriers with 2% mupirocin topical ointment eradicates S. aureus from the nose. No S. aureus isolates was found in reculture of nasal samples. Treatment of healthy carriers can significantly reduce the risk of infections caused by the bacterium in the ICU.

Abstract
Background and Objective: Considering the increasing tendency of public towards green consumption and the dangers of artificial additives, this study aimed to assess antibacterial activity of essential oils of Cinnamomum zeylanicum, Mentha piperita L., Zataria multiflora Boiss and Thymus vulgaris against three important pathogenic and spoilage bacteria (Pseudomonas fluorescens, Erwinia carotovora and Escherichia coli).
- After obtaining the essential oils from Magnolia Co., their antimicrobial activity was assessed using broth microdilution method by determining the minimum inhibitory concentration (MIC50, MIC90) and minimum bactericidal concentration (MBC). All experiments were performed in triplicate and the data were analyzed using the GraphPad software and Duncan's new multiple range test.
- All essential oils showed antimicrobial activity in a concentration-dependent manner. Increasing the concentration of essential oils from 0.01% to 4% (v/v) significantly enhancing the antibacterial activity. The statistical calculations and comparison of data showed that the essential oils of C. zeylanicum and Z. multiflora performed better compared to the other two essential oils, due to having lower values of MIC50 (≤0.1%), MIC90 (≤0.4%) and MBC (≤1%) (P <0.05).
- Considering the high antimicrobial activity of essential oils of C. zeylanicum and Z. multiflora, they can be used as effective food additives with fewer side effects. However, further studies are being conducted on the effectiveness of essential oils on the growth of other microorganisms and their results will be published soon.

Abstract
ABSTRACT
Background and objective: Surgery is the gold standard treatment for hydatidosis. Scolicidal agents could be used during surgery to kill
protoscoleces and prevent cyst recurrence after rupturing of main lesion. Non-chemical agents with sufficient
protoscolex-killing activity are known to be fully effective in this regard with fewer side effects. Fig tree is an Iranian native plant, which has been used for medicinal purposes in traditional medicine.
Methods: After obtaining infected hydatid cyst of the liver from a slaughterhouse in Babol (Iran), the percentage of live
protoscoleces was calculated by critical staining with 0.1 % eosin. Then, the protoscolex-killing activity of methanolic extract of fig leaves was evaluated at concentrations of 2.5, 5, 10, 15 and 20 mg/ml in 2, 4, 8, 12, and 16 minutes exposure times
. Statistical analysis was performed using SPSS software (version 22).
Results: Concentration of 20 mg/ml of the extract showed 100% protoscolex-killing activity within the first 2 minutes of exposure. In addition, the lowest protoscolex-killing activity (45%) was observed at concentration of 2.5 mg/ml after 2 minutes. The results also showed that the protoscolex-killing activity of the extract increases significantly in a concentration- and time-dependent manner (P <0.001).
Conclusion: The methanolic extract of fig leaf at concentration of 20 mg/ml could exert significant scolicidal effect within 2 minutes of exposure. Therefore, complementary experiments should be performed on animal models to further assess the efficiency of the extract for killing protoscoleces of hydatid cyst during surgery.

Abstract
ABSTRACT
Background and Objectives: Acinetobacter baumannii is an opportunistic pathogen that affects different groups of people, especially intensive care unit (ICU) patients. The prevalence of infections caused by this bacterium is very high. Today, prevalence of infections caused by multidrug-resistant (MDR) and extreme-drug resistant (XDR) strains is increasing. This study aimed to determine the antibiotic susceptibility pattern of A. baumannii isolates from ICU patients.
Methods: This cross-sectional study was conducted from October 2014 to March 2015 on patients admitted to ICU of Imam Khomeini hospital in Tehran, Iran. Clinical samples of various sources were collected from patients. Isolates were detected and identified via microbiological and biochemical tests as well as PCR amplification of the blaOxa51 gene. Then, susceptibility testing was performed using the Kirby-Bauer disk diffusion test. Statistical analysis was performed with SPSS (version 22, Chicago, IL, USA) using Chi-square and Fisher’s exact tests.
Results: Of the total of 62 clinical samples, 24 (39%) were respiratory samples and only three (6%) were cerebrospinal fluid samples. Most MDR and XDR strains were isolated from respiratory samples. The highest resistance rate was against ceftriaxone, ticarcillin and erythromycin (100%), while the lowest resistance rate was against to minocycline (20%).
Conclusion: Owing to detection of high multi-drug resistance isolates in the present study, and importance of multi-drug resistance in A. baumannii, the identification of multi-drug resistance genes and their reporting to health care/treatment centers is important. Thus, it is recommended to perform susceptibility testing to help determine the most effective antibiotic(s) for the treatment of infections in ICU patients.

Abstract
ABSTRACT
Background and Objectives: Efflux-based systems may play a role in resistance to fluoroquinolones in Gram-negative pathogenic bacteria. Extracts of some medicinal plants contain molecules that can act as efflux pumps inhibitors. In this study, we aimed to evaluate antibacterial activities of ethanolic and chloroform extracts of Cinnamomum zeylanicum and their possible synergistic activity with ciprofloxacin against some Gram-negative pathogenic bacteria. We also analyzed the extracts for presence of efflux pump inhibitors against the examined bacteria.
Methods: Powdered dried leaves and branches of C. zeylanicum were extracted with ethanol (85%) and chloroform by the maceration method. Minimum inhibitory concentrations of the extracts alone or combined with ciprofloxacin and phenylalanine-arginine β-naphthylamide (an efflux pump inhibitor) were determined against Pseudomonas aeruginosa, Acinetobacter bummani, Escherichia coli and Salmonella enteritidis using the double serial microdilution method.
Results: The extracts of C. zeylanicum inhibited the growth of all studied bacteria. Synergistic effects were noted between the extracts and ciprofloxacin against all tested bacteria other than P. aeruginosa. Ciprofloxacin efflux pumps in E. coli, S. enteritiditis and A. baumannii were inhibited by the extracts of C. zeylanicum.
Conclusion: The extracts of C. zeylanicum could be used as ciprofloxacin-potentiating agents against some Gram-negative pathogens.

ABSTRACT
Background and Objectives: Medicinal and aromatic plants are sources of natural antimicrobial compounds that could be useful replacements for antibiotics. The aim of this study was to assess antimicrobial activity of Crocus sativus stigma and Cinnamomum cassia extracts against some Gram-positive and Gram-negative bacteria.
Methods: Antimicrobial activity of methanolic and aqueous extracts of the plants was tested against clinical isolates of Klebsiella pneumonia, Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli and Enterococcus using the microdilution method. Minimal inhibitory concentration (MIC) and minimum bactericidal concentration of each extract against the mentioned bacteria were also determined.
Results: The MIC of the methanolic extract of C. cassia was 80 µg/ml against Enterococcus, K. pneumonia and E. coli. The MIC of the methanolic extract of C. sativus was 160 µg/ml against Enterococcus and S. aureus. The minimum bactericidal concentration of the methanolic extracts of C. sativus and C. cassia was 320 µg/ml against K. pneumonia and 160 µg/ml against Enterococcus.
Conclusion: The extracts of C. sativus and C. cassia exhibit promising antibacterial activities against clinical isolates of the tested bacteria. Our results suggest that the extract of these plants can be further exploited as potential antibacterial agents against multi-drug resistant bacteria.
Keywords: Cinnamomum aromaticum, Crocus, Anti-Bacterial Agents.

Abstract
Background and objectives: Leishmaniasis is a tropical disease caused by protozoan parasites from the genus Leishmania. In this study, we aimed at investigating the in vitro anti-leishmanial effect of essential oils of Rosmarinus officinalis, Mentha pulegium, Foeniculum vulgare, Lippia citriodora and Pelargonium graveolens.
Methods: The essential oils were prepared from freshly dried and powdered plants with steam-distilled water. Iranian strain of Leishmania promastigotes was cultured in RPMI medium and the inhibitory effects of different concentrations (25, 32, 62.5, 125, 250, 500 and 1000 μg/ml) of the essential oils were investigated at 24, 48 and 72 hours. The number of live parasites before and after treatment with the essential oils was counted by trypan blue 10% staining and using neobar lam.
Results: The essential oils significantly decreased the number of promastigotes in a dose-dependent manner (P<0.05). However, the inhibitory effects of F. vulgare and R. officinalis essential oils were more profound compared to other essential oils. Moreover, concentrations of 500 and 1000 μg/ml of these two essential oils exerted equal and more anti-leishmanial potency compared to glucantime, the first-line drug used for treatment of leishmaniasis.
Conclusion: Based on the results, it is recommended to evaluate the in vivo anti-leishmanial effects of the tested essential oils, particularly F. vulgare and R. officinalis.

Abstract
Background and objectives: Head louse, also known as Pediculus humanus capitis, is an obligate ectoparasite that is a distributed all around the world. The aim of present study was to determine the prevalence of head lice infestation in primary school students in Tabriz, East Azerbaijan Province, Iran.
Methods: Overall, 3,032 students (1,515 boys and 1,517 girls) from 33 primary schools in Tabriz were selected via multi-stage cluster sampling in 2018. The students were examined individually and privately by experts. Head lice infestation was confirmed by detecting adult or nymph or nits less than 1 cm from base of hair. Data analysis was carried out in SPSS software package (version 23). Association of participants’ characteristics with pediculosis infestation was evaluated using logistic regression and chi-square test at significance level of 0.05.
Results: Head lice infestation was present in 130 (4.29%) students, while the prevalence of this condition was higher in girls (2.11%) than in boys. The highest prevalence (6.05 %) was observed in children age 6 years old regardless of gender. The rate of head lice infestation was lowest among students aged ≥12 years (3.17%). There was a significant relationship between head louse infestation and parent’s occupation, family size, the frequency of combing and hair style.
Conclusion: Although the prevalence of head lice infestation in Tabriz is relatively low, screening and treating schoolchildren should be done continuously in order to reduce the infestation rate.

Abstract
Background and objectives: Urinary tract infection (UTI) is one of the most common bacterial infections. Staphylococcus saprophyticus is a common Gram-positive bacterium that causes uncomplicated UTIs in women. The present study aimed to study the drug resistance pattern and phenotypic and genotypic variation of S. saprophyticus isolates from women with UTI in Gorgan, northern Iran.
Methods: This study was performed from May 2018 to September 2020. During this time, 35 S. saprophyticus strains were isolated from patients with UTI. The antimicrobial patterns of the isolates were determined by a conventional method. Phenotypic criteria such as pigment production, mannitol fermentation, urease production, and 16SrRNA gene valuation were studied.
Results: All isolates were sensitive to nitrofurantoin, gentamicin, and linezolid. S. saprophyticus isolates showed the highest level of resistance to penicillin (85.7%) and erythromycin (51.4%). A variation was detected among S. saprophyticus isolates in terms of pigment production i.e. about 51.4% showed yellow pigment in Muller Hinton agar, and 62.9% of the isolates were able to ferment mannitol sugar. Of 11 isolates that were sequenced for the 16SrRNA gene, only two isolates showed different patterns.
Conclusion: Nitrofurantoin and trimethoprim-sulfamethoxazole are the antibiotics of choice for the treatment of UTI caused by S. saprophyticus in the study area. Due to the phenotypic and genotypic differences among S. saprophyticus isolates, typing of S. saprophyticus at the subspecies level is recommended.

Abstract
Background: Although the anti-diabetic effects of various Ficus species have been investigated in animal models, research on the blood glucose-lowering potentials of Ficus lacor Buch Ham bark remains sparse. This study evaluated the blood glucose-lowering potentials of an aqueous extract derived from Ficus labor bark in a diabetic rabbit model.
Methods: Diabetes was induced in rabbits through intravenous administration of alloxan monohydrate (120 mg/kg). 36 rabbits were divided into six groups, each consisting of six animals. Control groups included a non-diabetic control (Distilled water) and a diabetic control (Distilled water). Two experimental groups received Ficus lacor extract at doses of 100 mg/kg (Low-dose) and 200 mg/kg (High-dose) orally for six weeks. Metformin was used as an active control. A non-diabetic group (Extract control) was also administered Ficus lacor extract at 200 mg/kg. Fasting blood sugar (FBS) and post-prandial blood sugar (PP2BS) levels were measured weekly over the 6 weeks. The percentage reduction in blood glucose levels was calculated and compared for each group.
Results: The administration of both low-dose and high-dose Ficus lacor extracts resulted in significant reductions in FBS and PP2BS levels in diabetic rabbits. After six weeks, the low-dose extract group exhibited an average reduction of 38.3% in FBS and 40.5% in PP2BS, whereas the high-dose extract group showed average reductions of 35.3% in FBS and 36.3% in PP2BS.
Conclusion: The aqueous extract of Ficus lacor bark demonstrates substantial glucose-lowering activity, indicating its potential utility as a therapeutic agent in diabetes management.

Abstract
Background and objectives: The purpose of this research is to investigate continuous exercise and starvation in regulating the activity of the apoptotic pathway caused by endoplasmic reticulum stress in the liver of male Wistar non-alcoholic fatty model rats.
Methods :30 Wistar male obese rats, 18-20 weeks old, with an average body weight of 348 ± 25.53, , were selected as research samples. After one week familiarization with the laboratory environment, the fatty model animals were randomly divided into 6 groups of 5 Rat. The entire training course includes two familiarization stages (one week of adaptation to the research environment and treadmill) and the main training (for 4 weeks, 3 and 5 days a week for 45-60 minutes) on a treadmill with zero grade. The statistical test of one-way analysis of variance was used at a significance level of less than 0.05 and the LSD post hoc test was used among the research groups.
Results: According to the statistical results of the one-way analysis of variance, it showed a significant decrease in the ratio of lipoproteins (VLDL/HDL, LDL/HDL) in all experimental groups compared to the control group, and also a significant decrease in XBP1 and CHOP gene expression in the 5-day training groups. He showed 3-5 days of training with hunger.
Conclusion: Therefore, regular exercise along with starvation can prevent the progression of NAFLD by suppressing the excessive stress activity of the endoplasmic reticulum.
