Abstract
Background: Listeria monocytogenes has been identified as a serious food-borne pathogen. There is concern that raw dairy products maybe source of listeria strains responsible for human listeriosis. The aim of this study was determination of listeria from daily products which transferred to laboratory of food stuffs in Lorestan.
Materials and Methods: In this study 720 different dairy samples sent to the food stuffs control laboratory were analyzed for the presence of listeria spp. A series of test including catalase production, CAMP test, VP and fermentation of xy lose and manitol were used for listeria identification. Finally antimicrobic resistance was determined.
Results: Listeria monocytogenes was found in 9.72% of the samples and listeria innocua and listeria seeligeri were found in 5.83% and 1.11% of the samples, respectively. There were not any other isolated of listeria In the antibiogram, all of isolates were susceptible to penicillin, ampicillin, co-trimoxazole, and gentamycin and 5 isolates were resistant to erythromycin.
Conclusion: In view of that dairy products were ready to eat and there were possibility of contaminated by listeria spp. So, isolation and diagnosis of this in dairy products is important.

Abstract
Background: Coronary artery disease (CAD) is one of the most important and lethal
diseases in the world. CAD represents a board spectrum of disease from silent
ischemia at one end to sudden cardiac death at the other end. The middle of this
spectrum consists of acute myocardial infarction (AMI) and unstable angina pectoris
(UA). Recent data show that the inflammatory process plays a major role in the
pathogenesis of acute coronary syndrome. In this study we evaluated the difference in
complement factors C3 and C4 between AMI and UA, and the relation between early
completions of AMI and UA and the amount of C3 and C4.
Materials and methods: In this cross – sectional analytic study, 30 patients with
AMI and 30 patients with UA were compared with healthy subjects. Clinical and
laboratory data were collected. Blood samples were obtained on arrival and at 12.24
and 48 hours. electrocardiography and echocardiography were performed. All patients
were monitored for 14 days after discharging from hospital. For all patients ECG was
take on arrival and then daily bat.
Findings: Complement activation occurred in patients with AMI and UA. In AMI
activation of complement factors was significantly higher than in UA (p<0.01). In Qwave
MI and congestive heart failure, this elevation of activity was prominent
(p<0.01). In AMI a positive relation was found between complement factors and
Cratin phospho kinas level (r=0.71). There was a positive relation between
complement and mortality, and an inverse relation with ejection fraction (r=0.71).
There was significant difference among complement factors in the UA, AMI, and
control group (p<0.01).
Conclusions: Elevated levels of complement factors in AMI were related to the
degree of left ventricular ejection fraction (LVEF). Q-wave MI, and mortality.
However, in UA, elevated levels of complement factors were unrelated, with the
exception of the serum C3 level, which was related to LVEF.

Abstract
Background: Because of the scarcity of antifungal drugs,their undesired side effects and emergence of drug resistant strains research for finding novel antifungal drugs with less side effects is necessary. In this research, the antifungal effects of satureja khuzistanica essence,which is a native plant in our province, on ten kinds of fungi were evaluated.
Materials and methods: To extract the essence, we exploited water extraction by Clonger apparatus for dermatophytes and saprophytes. SDA media with different concentration of the essence were prepared and mean growth diameter of colonies were measured after 7 and 14 days. Disks with different concentrations were prepared for Cryptococcus neoformans and mean diameter of inhibition zones were measured after 7 and 14 days.The collected data were analyzed by SPSS software.
Findings: The results indicated that at concentrations equal to or more than 0.02 mg/ml,the essence inhibits the growth of Microsporum gypseum, Trichophyton mentagrophytes, Epidermophyton floccosum and at concentrations ≥ 0.06 mg/ml,it will inhibit the growth of Aspergillus fumigatus, Aspergillus flavus, Fusarium, Trichophyton rubrum, Trichophyton verrucosum, Microsporum canis (100% inhibition with two concentrations). For Cryptococcus neoformans,maximum concentration of 1000 mg/ml (pure essence) caused 62% inhibition.
Conclusions: The essence of S. Khuzistanica could be used for treating many fungal diseases and also as a disinfectant.

B.Sc of Nursing, Staff Member of Research and Technology Office, Lorestan University of Medical Sciences Abstract Background: With regard to the high prevalence of Giardiasis in elementary school children of most countries and the nececerity of rapid and sensitive detection of the disease in laboratories, this study was performed to compare routine parasitical assays and new techniques in antigen detection by Elisa for the detection of Giardia lamblia. Moreover, it was aimed to measure the prevalence of Giardiasis in Delfan town. Materials and methods: This study was an analytical-comparative study that was performed on 500 school children at elementary schools aged 6-12. After the selection of samples by systematic random sampling methods, the questionnaires were completed by every child and 3 fecal samples were collected from each child. The method of getting fecal samples from children was demonstrated for parents. All the samples were examined by wet-mount and Formalin-ether concentration assays. Then, the Elisa technique was performed to all samples and the findings were compared. Results: Out of 500 male and female subjects aged 6-12 in Delfan elementary schools, 97 samples examined by three laboratory techniques (Wetmount, Formalin-ether concentration, and Elisa) were found to be positive for Giardia lamblia. %19.4 of the subjects (68) were positive for Giardia lamblia, (%70.1) in Wetmount assay, 88 samples (%90.72) in Formalin-ether concentration test, and 95 samples (%97.93) in Elisa technique. Conclusion: The findings of this study revealed that Elisa technique in comparison to routine parasitical assays for Giardia detection was more sensitive and rapid. This technique does not need experts to be carried out and it shows organisems with minimum amounts of Giardial antigens in their feces. This technique can examine more samples in a shorter time. The findings demonstrated that the prevalence of Giardiasis in elementary school children in Delfan town is almost high and needs more hygiene education and instruction.

Abstract
Introduction: Particulate matter refers to the combination of atmospheric pollutants that a portion of this particulate is bioaerosol. The aim of this study was the evaluation of bacteria, fungi and biomass in particulate matter in ambient air of Khorramabad during summer and autumn 2012. Materials and Methods: This study was a cross sectional study that conducted in Khorramabad city during summer and fall 2012. Sampling has been done via high-volume sampler. The special cultures were used for cultivation and determination of fungal and Heterotrophic Plate Count (HPC (and Bradford method were used to determine bacteria and protein as biomass indicator, respectively. Relationship between these variables with metrological parameters was evaluated too. Results: The highest PM10 in July (257.18 µg/m3) and lowest in September (92.45 µg/m3) had been recorded. The highest amount of bacteria and fungi were measured as monthly in November (605 No/m3) and December (120 No/m3), respectively. The highest of protein concentration was measured in August, September and December (27-30 µg/m3). With the increase in PM10, biomass concentration in the air showed a meaningful increase. Conclusion: Biomass concentration in the air increased with increasing PM10 but it had no significant effect on the concentration of bacteria and fungi in the air. Meteorological factors such as temperature, humidity, wind speed, solar radiation and the amount of exposure time had a significant impact on bioaerosol concentrations in the air.

Abstract
Background: The climate change and particulate matter emission contented of bioaerosols is known as an important reason of increasing the allergic interactions especially in patients with defect in immunity system. The aim of this study was to investigate fungal bioaerosol concentrations in relation to particulate matter (PM10, PM2.5 and PM1) in indoor parts and ambient air of the generd educational hospital of Khorramabad city.
Materials and Methods: In this descriptive-analytical study, 192 samples (168 for indoor and 24 for outdoor) were gathered during 6 months at the seven indoor wards and one outdoor unit using Quick Take-30 method at an airflow rate of 28.3 L/min and sampling time of 2.5 min on to Sabouraud dextrose agar medium containing chloramphenicol. The sampling of particulate matter was carried out by Monitor Dust-Trak 8520. Also, the relative humidity and temperature were surveyed by TES-1360 digital.
Results: The results showed that infectious ward with 101.7 CFU/m3 was as the most contaminated part and operating room with 46.4 CFU/m3 was the cleanest part. Cladosporium with 36.75% and Rodotorolla with 1.3% had higher and lower of fungi rates, respectively. The rate of I/O<1 illustrate that this contamination had an outdoor source.
Conclusion: The surveys demonstrated that the increase of temperature and relative humidity have an effective influence on the pollutant accumulation. In addition, between fungi bioaerosols frequency and particulate matter ther was a significant correlation.

Abstract
Background: Toxoplasma gondii is one of the most common zoonotic parasites. The stray cats play an important role in the infecting intermediate hosts, due to easy access to raw meat and predation of infected rodents and birds and shedding oocyst on the environment. The aim of this study was to determine the prevalence of T. gondii antibody in the serum and oocyst shedding in the feces of stray cats and its relationship with some variables such as age, sex and inhabitant in Khorramabad, west of Iran
Materials and Methods: A total of 125 Stray cats trapped from different parts of city and were brought to the research laboratory to take blood and faces specimens. The blood samples of the cats (71 males and 54 females) were assayed for the prevalence of T. gondii using the IgG-ELISA, and their fecal samples collected through rectal swabs, and sugar floatation concentration method was applied for detection of oocyst.
Results: From 125 cats, a total of 80 cats (64%) were positive for anti-Toxoplasma antibody, 42 cats (33.6%) were negative and 3 cats (2.4%) were in borderline. There was no significant difference in the T. gondii seropositivity between males and females, and also between cats living in different parts of city, but prevalence rate between different age groups were significant statistically (P<0.021). T. gondii-like oocysts were detected in only 3 of 125 samples tested from cats’ stool by direct microscopy and floatation methods (the oocyst size was out of the range and identified as Isospora sp.).
Conclusion: The present study indicated a significant proportion of cats from Khorramabad, west of Iran. The T. gondii infection risk could be considerable if public health measures didn't take into account.

Abstract
Background: The increasing number of patients suffering from cutaneous leishmaniasis in Poldokhtar County during the last 10 years and technological advances in data generation has increased the necessity to produce the predicting models of disease prevalence in the region. Therefore, climatic variables were used in this study to predict the cutaneous leishmaniasis.
Materials and Methods: In this study using regression model, the relationship between number of patients with cutaneous leishmaniasis and climatic signals were taken simultaneously and with one, two, three and four months of regression lag.
Results: Totally there was a significant relationship between January patients with January NINO1 climatic signal, March patients with February PNA climatic signal, April patients with March AAMM climatic signal, May patients with April AO climatic signal, and August patients with June TSA climatic signal, at 5% significance level. Furthermore, there was a significant relationship between February patients with January NINO1 climatic signal, at 10% significance level.
Conclusion: This investigation showed that use of climatic signals with lags for predicting the disease was better than simultaneous application of signals and disease. Correlation between statistics relating to diseases during the entire period and PDO signal with 2 months of lag was obtained as 84.53. In addition, results indicated that approximately during half of the months in a year, there was a good correlation between prevalence of cutaneous leishmaniasis and the climatic signals and thus enabling us to discover prevalence of cutaneous leishmaniasis using the climatic signals.

Abstract
Background: Autism spectrum disorder is the most commonly occurring growth disorder. A deficiency in social skills, interests, behaviour and repetitive and limited actions, and a deficiency in communication and social interactions are the hallmarks of autism.
Materials and Methods: this research was a one-group semi-experimental study run by storytelling with a role playing method on studied units. The target population in this study were all patients with autism, who had registered in autism centers in Khorramabad city in 1396 (2017). 30 autistic children aged 6-16 years were selected using an available sampling method. The children were divided into 6 groups of 5 people. The intervention was conducted during 15 sessions of 45 minutes for each group, with a maximum of three stories in each session performed by the Carroll Gray method (a total of 90 sessions in two months). The data was collected and then processed by the ATEC questionnaire before and after the intervention.
Results: The results of analytical tests showed that the communication and social skills of the children before and after the intervention had a significant difference. A communication skill (speech, language, and communication) mean of 0.885 before the intervention, was followed by one of 1.2 afterwards. The correlation between the responses before and after was 0.532, which is significant, with Sig= 0.002. The social skills mean of 0.885 before the intervention, was followed by one of 1.2 afterwards. In this context. The correlation between the responses before and after was 0/684 which is significant, with Sig = 0.000.
Conclusion: The findings show that storytelling with a role play method is one of the most effective and economical therapeutic interventions for improving the communication and social function of children with autism.

Abstract
Background: This study aims to evaluate the scolicidal effects of oak (Quercus infectoria) extract on hydatid cyst protoscoleces in vitro and ex vivo.
Materials and Methods: Following the collection of protoscoleces from sheep livers infected with fertile hydatid cysts from a slaughterhouse in Khorramabad, they were treated with various concentrations of oak extract (250-1000 µg/mL) for 5-40 min in vitro and ex vivo. Finally the mortality of protoscoleces was assessed by the eosin exclusion test (0.1% eosin staining).
Results: The mean of the mortality of protoscoleces was 100% after 5 min incubation with the concentration of 1000 mg/ml of oak extract. On the other hand, the mean of the mortality of protoscoleces after 10 incubation with the concentration of 500 mg/ml of oak extract was 100%. However, these results were not observed in the ex vivo analysis. That is, oak extract requires a longer length of time to display potent protoscolicidal effects.
Conclusion: The results of this investigation revealed that oak extract could have a significant scolicidal activity on hydatid cyst protoscoleces. However, further research, particularly in human and animal subjects, is required to reach this conclusion.
Keywords: Hydatidosis, Echinococcus granulosus, extract, hydatid sand, hcolicidal.

Abstract
Background: COVID-19 was a global epidemic that led to numerous problems, including menstrual disorders in women. The present study aimed to assess the frequency of menstrual disorders and related factors in women with COVID-19.
Materials and Methods: The descriptive study was conducted on 80 women with COVID-19 in the first six months of 2022. Information was collected using a telephone questionnaire and data analysis was performed in SPSS software (version 16) using descriptive statistics (frequency and percentage) and analysis (chi-square and independent t-test).
Results: Based on the results, 43.7% of women had menstrual disorders during the COVID-19 pandemic. Among these women, 26.3% and 17.5% of cases considered the disorder to be related to receiving the COVID-19 vaccine and COVID-19 infection, respectively. Massive bleeding (17.5%) and low-volume bleeding (7.5%) were the most reported disorders, and Sinopharm (76.3%) and AstraZeneca (15.0%) vaccines were the most used vaccines. The results of statistical tests did not demonstrate a significant relationship between the presence of disorder and other variables (P>0.05).
Conclusion: Menstrual disorders increased during COVID-19 compared to before. Considering the resolution of this disorder after several months, it is recommended that if the disorder is not resolved, it should be referred for identification and follow-up in time to reduce the dangerous consequences of women's diseases.
