Background & objectives: Candidiasis is a fungal infection which is caused by Candida spp. Candida albicans is the most common agent of candidiasis. This infection may cause various side effects during pregnancy including prematurity, chorioamnionitis, candidal pneumonia, and systemic candidiasis of infants. This research was conducted for determining the prevalence and antibiotic resistance pattern of Candida spp, collected from pregnant women admitted to health centers in Ardabil, Iran.

Methods: Totally, 408 subjects were included in this study. Demographic data and risk factors were recorded using a questionnaire. Two swab samples were taken from vulvovaginal mucus. One swab was used for preparing smear and direct microscopic examination and the second one used for cultivating the specimen. After identification of Candida spp., antimicrobial resistance pattern was determined by disk diffusion method against Fluconazole, Ketoconazole, Clotrimazole, Nystatin and Amphotericin B. Results were interpreted according to CLSI guidelines. The data were analyzed by χ² and t-test using SPSS-19.

Results: Out of 408 subjects, 143 cases (35%) were positive for candida spp. The Candida albicans with 119 (83.2%) cases was the most prevalent species followed by Candida glabrata, Candida krusei, Candida parpsilosis and Candida tropicalis.According to disk diffusion test, overall 116 (81.1%) isolates were resistant to Fluconazole, 100 (69.9%) to Ketoconazole, 67 (46.9%) to Clotrimazole and 25 (17.5%) to Amphotericin B. Candida spp. had a highest sensitivity (118, 82.5%) to Nystatin. For Candida albicans 97(81.5%) isolates were resistant to Fluconazole and 99(83.2%) isolates to Nystatin. For Candida glabrata 10 (90.9%) isolates were resistant to Fluconazole, and 9(81.8%) sensitive to Nystatin.

Conclusion: According to the results of this study, vulvovaginal candidiasis is prevalent among pregnant women in Ardabil and isolates were significantly resistant against commonly used antifungal drugs. Nystatin was the most effective against Candida spp. As antibiogram for fungal agents is not routinely performed, the similar periodical studies could be useful for choosing appropriate antibiotics in treatment of vulvovaginal candidiasis.

Background & objectives: Nowadays, bacterial resistance and the increase in the therapeutic costs are considered as the most important global concerns of medical care system regarding complicated infections. Imipenem is a member of the carbapenem class of beta-lactam antibiotics prescribed mostly in our hospitals because of its broad activity against bacterial infections. Drug Utilization Evaluation (DUE) process is an official, ongoing and systemic program that collects information in order to identify and improve the adverse effect of drugs and the cost of medicalization. The objective of this study was to evaluate the administration and use of imipenem in the educational Imam Khomeini hospital in Ardabil in 2018.
Methods: In this prospective, descriptive, cross- sectional study, 110 hospitalized patients, who received imipenem from September to December of 2018, were included in this study. Patient's demographic data, dosing, dosage adjustment in renal failure and other co-prescribed antimicrobial drugs were extracted from current medical file of hospitalized patients and evaluated with medical guidelines.
Results: 64% of patients received imipenem in the first day of hospitalization and 75.5% of patients were empirically received imipenem while antibiogram test was ordered for only 24.5% of patients. Serum creatinine were ordered for most of the patients, but correct dose regimens for patients who get non-empiric antibiotic therapy were only 25.5%.
Conclusion: High rate of empiric prescription without considering the result of antibiogram test and immediate initiation of antimicrobial therapy at the time of admission were the most important aspects of irrational use of imipenem observed in this study. Paying more attention to sampling, culturing and sensitivity test and prescription of imipenem based on specific guidelines are recommended.

Background & objectives: Pentavalent antimonials are the first-line drugs for treatment of leishmaniasis, which have multiple side effects such as drug toxicity. Moreover, parasite resistance to these drugs is rising around the world. Second-line drugs, including Amphotericin B and pantamidine have also side effects and expensive for patients. According to the cytotoxic effects of paraquat, this study was conducted to evaluate the effect of paraquat on Leishmania major promastigotes and HUVECs viability.
Methods: A number of 2.5×10⁶ of Leishmania major promastigotes were treated in each well of 96 well plates with different concentrations of paraquat. Cells were incubated for 48 hours in 24 °C. MTT test was performed for evaluating paraquat impact on promastigotes. The absorbance was measured using a microplate reader at 570 nm.  The trypan blue staining assay was performed to evaluate the number of viable Leishmania major promastigotes following paraquat treatment. Furthermore, the effect of paraquat concentrations on HUVECs viability was evaluated under the cell culture condition.
Results: The results of the MTT test showed that increasing concentrations of paraquat could significantly reduce the viability and the number of Leishmania major promastigotes in comparison to control group (p<0.05). In this study, the IC₅₀ for Leishmania major promastigotes was calculated as 272.46 µg/ml. Trypan blue results were in line with the finding of MTT assay. Moreover, we found that HUVECs were susceptible to paraquat (IC₅₀=188.99 µg/ml).
Conclusion: Paraquat has a strong inhibitory effect on Leishmania major promastigotes and human endothelial cells. Although more comprehensive studies on the effects of the topical use of paraquat on Leishmania major lesions in animal model and its side effects are necessary.

Background & objectives:  Hydatid cyst is a major hygiene problem in Iran. In 80% of cases, only one organ is involved. However, multiorgan involvement has also been rarely reported. But it seems, the prevalence of hydatid cyst with the involvement of more than one organ in Iran is more than other world. The aim of this study was to evaluate the patients with hydatid cyst multi organ involvement in Ardabil province in northwest of Iran.
Methods: In this retrospective study, 34 patients with hydatid cyst with involvement in more than one organ were included. For each patient, a pre-designed questionnaire including name, age, education level, occupation, place of residence, cyst location, clinical manifestations and serologic test results were completed. Patients, who had previously a history of treatment due to hydatid cyst, were excluded from the study.
Results: The mean age of patients was 36.41 years. 61.8% of the patients were housewives and 64% were rural residents. The most commonly involved organs was liver and simultaneous involvement of liver and lung was observed in 38.2% of patients and was more in women. The association of the right lung cyst with the liver cysts was greater than that of the left lung. Only in 43% of the patients, the serologic test was positive for hydatid cyst, and the relationship between serologic test and type of involvement was not significant.
Conclusion: Regarding the high incidence of hydatid cyst involvement in more than one location in our region, in all patients, especially women with liver hydatid cyst, other organs, especially the lungs, should be investigated

Background & objectives: Due to the increasing prevalence of bacterial resistance, there is a growing attention to application of auxiliary treatment of pharyngitis. The aim of this study was to investigate the effect of honey throat spray in the auxiliary treatment of patients with a diagnosis of pharyngitis.
Methods: At the start, different physicochemical quality parameters of the honey sample were evaluated. Then, the bottles of honey and the placebo throat spray were prepared. The numbers of 70 patients with the diagnosis of pharyngitis were included in a one-step and double-blinded study. In addition to standard treatment, each patient received either one of the honey or placebo throat spray. The clinical symptoms of the patients were compared between the two groups at baseline and then at 24 hours, 48 hours, 5 days and 10 days after the starting the treatment procedure.
Results: As per results, the quality of honey sample was met to the standard honey criteria. The treatment and placebo groups were statistically similar in terms of demographic specifications or clinical symptoms at the time to enter the study. Pharyngitis recovery was better in treatment group than in the placebo group; this positive effect was statistically significant for symptoms of morning phlegm and painful swallowing, 24 hours after the starting treatment. In treatment group, after 48 hours, symptoms of fever and painful swallowing were resolved, while this indicator was 23% in placebo group. Also, throat pain of 85.71% of patients in treatment group and 17.14% of patients in placebo group was relieved. Overall, the mean recovery time in treatment group was shorter than placebo group.
Conclusion: The findings of this study showed that the use of honey throat spray as auxiliary treatment of pharyngitis can improve the clinical symptoms of pharyngitis and reduce recovery time.

Background & objectives: Drug-repurposing is the study on application of existing drugs for treatment or control of other diseases. Major advantage of the technique relies on a nominated drug molecule that is applied for pharmacodynamics optimization due to lack of serious pharmacokinetics challenges. According to the importance of the subject, a present contribution has been dedicated to the in-silico analysis of a few drug classes with the aim of achieving potential anti-leishmanial pharmacophores.   
Methods: 3D structure of protein targets within leishmania parasite were retrieved from Brookhaven Protein Data Bank (PDB) on the basis of literature reports to evaluate the related complexes with drugs via molecular docking. Qualitative and quantitative analysis of drug-target interaction patterns in docked complexes offered drugs with higher binding affinities toward targets and finally structural patterns or hypothetical anti-leishmanial pharmacophores were proposed with regard to the top-ranked pharmaceutical compounds.
Results: Highest free binding energy could be estimated for Nateglinide in binding to farnesyl diphosphate synthase (ΔG_b -13.30 kcal/mol). Among steroids, Norgestrel synthase (ΔG_b -9.48 kcal/mol) and Testosterone synthase (ΔG_b -8.05 kcal/mol) exhibited higher enzyme binding affinities and Arg82 was a key residue in making hydrogen bonds. Within fused tricyclic structural patterns, mirtazapine exhibited highest binding affinity to deoxy uridine triphosphate (ΔG_b -8.64 kcal/mol). In Carbamazepine, amide substituent of the central ring facilitated the formation of two effective hydrogen bonds with Gln21 and Asn25 in deoxy uridine triphosphate. 
Conclusion: On the basis of obtained results for steroids and fused tricyclic scaffolds, it will be possible to design molecules that can inhibit several pathogenic targets simultaneously.

Background & objectives: The deposition of amyloid beta (Aβ) peptide in the brain is one of the most important features of Alzheimer's disease. In addition to memory loss, Aβ can lead to depression behavior. Alpha-pinene is a type of monoterpene that has antioxidant, anti-inflammatory, and neuroprotective effects. Here, by using an animal model for Alzheimer's disease, we investigated the effect of alpha-pinene on neuronal cell death in the hippocampus and depression induced by Aβ_1-42.
Methods: Male Wistar rats weighing 240-260 g were divided into four groups including control, alpha-pinene, Aβ, and Aβ-alpha-pinene. Rats were placed in stereotaxic surgery apparatus and Aβ_1-42 was injected into the hippocampus (4 µg per side) and alpha-pinene was treated intraperitoneally (50 mg/kg) for 14 consecutive days. At the end of the course, the level of depression was assessed using the forced swimming test. The animals' hippocampus was also examined microscopically after Nissl staining.
Results: Intra-hippocampal injection of Aβ_1-42 increased the total immobility time in the forced swimming test (p<0.01), decreased the number of pyramidal neurons in the CA1 area (p<0.001), and reduced the thickness of the neuronal layer in this region of ​​the hippocampus. Treatment with alpha-pinene largely prevented these changes.
Conclusion: It can be concluded that alpha-pinene decreased the beta-amyloid-induced depressive behavior in rats and inhibited the neuronal loss, suggesting that this neuroprotective compound may have a critical role in depression. Alpha-pinene is probably a suitable therapeutic strategy for repressing Aβ-induced neurodegeneration
