A Ebrahimzadeh, S Mohammadi, T Davoodi, Ar Salimi Khorashad, A Jamshidi,
Volume 7, Issue 3 (Autumn 2013)
Abstract
Abstract Background and Objective: Toxoplasmosis is one of the most prevalent parasitic infections worldwide. Contamination of pregnant women with toxoplasmosis may cause fetal death, preterm delivery and congenital toxoplasmosis. Due to importance of congenital Toxoplasmosis and the need of further study, this research was accomplished in Zahedan. Material and Methods: The serum samples (N= 221) were collected from pregnant women referring to reference laboratory of Zahedan in 2011. The IgG and IgM antibody levels against toxoplasmosis were investigated using ELISA method. Results: Out of all samples, 30.8% are IgG positive and 1.4% are both IgG and IgM positive. There is no significant difference between positive and negative groups using Chi-square tests. Conclusion: The main part of pregnant women in Zahedan (69.2%) is serologically negative against toxoplasmosis therefore, hygiene education to eliminate risk factors especially during pregnancy period seems to be imperative.

Volume 8, Issue 1 (spring[PERSIAN] 2014)
Abstract
Abstract Background and Objective: Cervical cancer is the second most common cancer in women. Boswellia serrata is a medicinal herb with anticancer, antibacterial, antiulcer, antifungal properties. Since the antitumor effect of this medicine has not been studied on cancer cell lines, we aimed to investigate the antitumor effect of Boswellia serrata on cervical cancer cell lines. Material and Methods: To assess the anti-cancer effect of Boswellia serrata extract, HeLa cell lines were cultured , propagated and placed with different doses of Boswellia serrata (12.5,25, 50 and100 µg/ml) for 24,48and72 hours. After that, MTT test was used to determine the cellular toxicity of the extract. Results: The results of the MTT test showed that this extract has dose-dependent and time-dependent anti cancer effect on Hela in that the highest effect was seen with 100 µg/ml of extract for 72 hrs. The half maximal inhibitory concentration (IC50) for 24 and 48 hrs were 12.5 and 50 µg/ml, respectively. In 72 hours, due to increase of incubation period in all concentrations, the number of killed cells was more than 50 percent. Consequently, IC50 was not observed for this period of time. Conclusion: Considering dose-dependent and time-dependent anti cancer effect, Boswellia serrata extract can inhibit the growth of Hela cells.

Volume 12, Issue 4 (Jul-Aug 2018)
Abstract
ABSTRACT
            Background and objectives: The present study was conducted to detect class 1 integrons and evaluate antibiotic susceptibility patterns among clinical isolates of P. aeruginosa.
            Methods: Sixty clinical samples from blood, tracheal wounds, burns and urinary tract infections were collected from three general hospitals in Tehran, Iran. Culture of specimens was performed on common bacteriological culture media. Bacteria were  identified based on mobility, pigment production, growth at 42 oC, and oxidase and catalase tests. Overall, 21 P.  aeruginosa strains were isolated. Antimicrobial susceptibility of was evaluated via the disk diffusion method (Kirby-Bauer) according to the CLSI guidelines. Presence of the intI1, sul1, aadA2 and aadB gene cassettes was investigated using PCR. The collected data were analyzed using SPSS software (version 21).
            Results: The most effective antimicrobial agents against P. aeruginosa isolates were tetracycline and gentamicin. All P. aeruginosa isolates were multidrug re­sistant. Moreover, the intI1, sul1, aadA2 and aadB genes were found in 90.5%, 90.5%, 47.6% and 19% of the P. aeruginosa isolates, respectively.
            Conclusion: The results indicate that the presence of aadB, aadA2 and sul1 gene cassetes may play an important role in the dissemination of antimicrobial resistance determinants.
          Keywords: Pseu­domonas aeruginosa, integron, multidrug resistance.

Perovskia abrotanoides Kar. as a Promising Source of Antimicrobial Compounds against Foodborne Pathogens
Farzane Maryam, Poozesh Vahid, Atefe Amirahmadi, Fatemeh Salimi,
Volume 17, Issue 3 (May-Jun 2023)
Abstract
Background and objectives: Foodborne pathogens can significantly affect the public health and cause medical, social, and economic burden. Listeria monocytogenes, Salmonella ­enterica, and Yersinia enterocolitica are important foodborne pathogens that can cause various diseases. Plant-derived compounds are promising bioactive substances with inhibitory effects against bacteria. Perovskia abrotanoides Kar. is a medical plant with broad therapeutic activities. In the present study, we aimed to investigate the inhibitory effects of P. abrotanoides extracts against some foodborne pathogens.
Methods: Flowering branches of P. abrotanoides were collected in 2018 and 2019 from three different habitats in the eastern Alborz Mountains, Iran. The antimicrobial activity of the extracts was evaluated using the agar well diffusion test. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the extracts were determined against L. monocytogenes, S. ­enterica, and Y. enterocolitica. In addition, the antioxidant activity of the extracts was investigated by the DPPH test.
Results: The lowest MIC (200 µg/ml) and MBC (400 µg/ml) values against Y. enterocolitica were related to the ethyl acetate extract of plants collected from habitat 1 in 2019. The lowest MIC (50 µg/ml) and MBC (400 µg/ml) values against L.­­ monocytogenes were related to the dichloromethane extract of plants collected from habitat 1 in 2019. All extracts showed antioxidant properties. Results of one-way ANOVA indicated that the DPPH scavenging activity of extracts from plants collected in 2019 was greater than that of those collected in 2018. In most cases, the methanol and ethyl acetate extracts showed more radical scavenging potential.
Conclusion: It seems that P. abrotanoides is a rich source of antimicrobial and antioxidant compounds with great potential for use in the pharmaceutical and food industries.
