Background: The coronavirus pandemic has created the most fatal health crisis in humanity in the recent century. The present study was designed to investigate the relationship between employees' spirituality and organizational vitality in the outcome of the health carers' work in Hajar hospital, an army hospital in Tehran, during the first year of the COVID-19 pandemic. The main purpose was to determine any significant relationships between staff spirituality and organizational vitality.Methods: This descriptive survey study was performed from March 2019 to February 2020. Seventy-one employees were recruited as the sample size using the Morgan table. The characteristic of the components of employees' spirituality were examined by performing Kingerski and Skrypnek questionnaires. All variables of the organizational vitality were determined using Rojelf model and a researcher-made questionnaire which was approved by the relevant experts. To analyze the data for determination the relationship among indicators, the structural equation model was exercised using LISREL software.Results: Most of the cases were between 21 and 39 years old. The results showed that there were significant relationships between all examined characteristics of the employees' spirituality and organizational vitality.Conclusion: The results confirmed that there were significant relationships between spiritual desire, spiritual connection, sense of unity, mystical experience and the organizational vitality components including positive thinking, organizational learning, organizational participation, organizational openness, meaningful life, and interest. Accordingly, determining the effects of interactions among those values in their reciprocal promotions are deserved to be seriously studied to achieve an advanced and successful COVID-19 disease management.

Background: Toxoplasma gondii is an obligatory intracellular parasite causes toxoplasmosis. The parasite has two forms, noninvasive bradizoites and invasive tachizoites. The present study, for the first time, aimed to evaluate the effect of vitamins C and E on nitric oxide (NO) elevation to promote killing invasive tachizoites by macrophages in susceptible BALB/c mice.Materials and Methods: Seventy BALB/c mice were recruited and randomly divided into fourteen groups of five (n=5). Control groups: one group left intact. Two groups were given saline or methanol. Two groups were infected with 104 or 5×104 parasites. The other groups were administrated only vitamin C, E, or both. The rest of sample and control groups were infected with either 104 or 5×104 tachizoites and supplemented with 100 µl vitamin E every other day, or 200 µl of vitamin C daily. Vitamins were intraperitoneally administered up to five days. On sixth day mice were intraperitoneally infected with tachyzoites. The blood samples were taken three days post infection, serum collected and stored at - 20 Cº until examinations. The peritoneal macrophages were isolated for counting phagocytised tachyzoites and nitric oxide assays.Results: Tachyzoites were significantly decreased after vitamin C & E administration in the infected mice compared to the controls. In mice supplemented vitamins NO levels were significantly higher compared to controls. Conclusion: Our findings showed that administration of vitamin C, E or both significantly enhanced killing invasive parasites through NO elevation produced by activated macrophages and may have therefore, complementary therapeutic effects.

Background: Although all the advances of medical science has come to achieve, parasitic infections including intestinal parasites in many countries especially in developing countries, is a health problem; according to the annual fees paid by that the World Health Organization and governments to eliminate, prevent and treat them, their existence is still visible. In this study the prevalence of intestinal parasite in mental disability community in Ardabil city will be studied. Materials and methods: This descriptive cross-sectional study with was design to detect the prevalence of intestinal parasites on the 216 cases of mental disability under the Social Welfare Organization in Ardabil city, with methods of direct smear, formalin ether concentration method and Modified ziehl-neelsen staining. Results: From 216 patients 95 samples (44%) were infected with at least one parasite including Blastocystis hominis 41 cases (19%), Entamoeba coli cyst 25 cases (11.6%), Giardia cyst 18 cases (8.3%), Trichuris trichura egg 2 cases (0.9%) and contemporary infection with two parasite Entamoeba coli / Blastocystis hominis cysts and Entamoeba coli / Iodamoeba butschili cysts 4 (1.9%) and 3 (1.4%) cases respectively. In 0.5% of cases we found Entamoeba coli cyst with 4 nuclei cysts.
Conclusion: According to the results, levels of intestinal parasitic infections in mental disability community in the Ardabil city in compare to other communities was higher that need to pay more attention of the authorities.

Background and Purpose: Among Bacilli, Bacillus cereus, Bacillus thuringiensis and Bacillus anthracis are important and the latter causes anthrax. Toxin production in this bacillus is carried out by pxo1 gene and associated plasmid. Research has recently shown that this gene can transfer to other bacilli too. The present study was conducted to determine the frequency of pxo1 gene in bacilli other than Bacillus anthracis, so that they can be safely used in producing vaccines against anthrax. Methods and Materials: In this cross-sectional descriptive analytical study, 65 soil samples were collected from different geographical regions in Iran, and the organisms were isolated from the soil. Proteins isolated from bacilli were examined by SDS-PAGE technique, and the limits of coded proteins by pxo1 gene were specifically located. The data were summarized in Excel using figures and tables. Results: Based on the results, 13 out of 38 bacilli showed protein bands in the proteins coded by pxo1 gene, and all were from cereus family. Conclusion: In Iran, pxo1 plasmid has transferred from Bacillus anthracis to 13 bacilli isolated from Bacillus cereus.

Background and Purpose: Vulvovaginal candidiasis is one of the most common infections in women and is caused by various types of candidiasis with different patterns of resistance against drugs. The present study was conducted to determine the various species of candidiasis in women admitted to Mobini Hospital in Sabzevar, Iran in order to make preventive recommendations for medical doctors. Methods and Materials: This cross-sectional descriptive analytical research was conducted on 231 women admitted to Mobini Hospital in Sabzevar, Iran, complaining of vaginal secretions. After getting the ethics committee permissions and obtaining the informed consent of the participants, at the same time as measuring vaginal pH, two swaps were used for collecting samples of secretions from lateral and posterior fornix. They were examined for yeasts and were then cultured in saburu dextrose. Grown yeasts were detected based on their macroscopic and microscopic features, tubulation in blood serum and biochemical characteristics using Yeast Plus System. The obtained data were analyzed in SPSS 11 using chi-square and bi-dimensional tables. Results: Positives results in direct examination results were 7.35%, and in culture the positive results were 26.8%. In detecting processes, candida albicans yeast (38.7%), Candida kefyr (17.7%), Saccharomyces cerevisiae (14,5%); candia tropicalis (9.6%), Candida glabrata (8%), candida cruse (3.2%) were isolated with other non-pathogenic yeasts including Candida rugosa, Candida lipolytica, trycospron bejli, Blastoschizomyces capitatus (6.4%). Conclusion: Non-pathogenic yeasts were isolated from patients with defective immunity systems, and need to be considered in patients with vaginal infections.
