Polymorphic nature of this gene is a major obstacle in making an effective vaccine against malaria. In this study, the genetic diversity of Plasmodium falciparum isolates was investigated in Sistan-Baluchestan Province using allelic families of the MSP-1.        Methods: From March/April 2011 to August/September 2012, 94 blood samples were collected from patients with falciparum malaria who were living in four districts of Sistan-Baluchestan Province. The extracted genomic DNA and genetic diversity of MSP-1 block 2 were evaluated by nested polymerase chain reaction.         Results: From a total of 94 patients, 89 patients (94.7%) had positive PCR results and the remaining five patients were excluded. Seven different alleles of MSP-1 were identified through size difference on agarose gel. Comprising 46.1% of the samples, MAD20 was identified as the predominant MSP-1 allelic family, while the RO33 family had the lowest frequency (with 7.9%). In 10% of samples infection with two alleles was observed.          Conclusion: The results of this study suggest that genetic diversity of PfMSP-1 in Southeastern Iran is relatively low and most infections originate from a clone that is consistent with an area of low malaria transmission. This information is useful for the prevention and control of malaria in Iran.           Keywords: Merozoite Surface Protein 1, Plasmodium Falciparum, Polymerase Chain Reaction  }, Keywords = {Merozoite Surface Protein 1, Plasmodium Falciparum, Polymerase Chain Reaction}, volume = {9}, Number = {4}, pages = {1-5}, publisher = {school of paramedicine, golestan university of medical sciences}, doi = {10.18869/acadpub.mlj.9.4.1}, url = {http://mlj.goums.ac.ir/article-1-771-en.html}, eprint = {http://mlj.goums.ac.ir/article-1-771-en.pdf}, journal = {Medical Laboratory Journal}, issn = {}, eissn = {2538-4449}, year = {2015} } @article{ author = {Ghasemi, Behzad and Najimi, Mohsen and Beyzaei, Hamid and Jamshidian, Abbas}, title = {Antibacterial Effects of Novel Thiazole Derivatives and the Toxicity of Oxothiazole on Liver Histopathology of Mice}, abstract ={Abstract       Background and Objectives: Antibiotic resistance in bacteria has actuated researchers toward evaluating many new antibacterial compounds of which are the thiazoles. In this research the inhibitory effects of novel thiazole derivatives were unraveled on Staphylococcus aureus, Streptococcus agalactiae, Pseudomonas aeruginosa and Klebsiella pneumoniae and oxothiazole liver toxicity effects were assessed on mice.        Methods: The antibacterial effect of thiazole derivatives was evaluated by measuring the halo zone with disk diffusion method and dilution procedure in microplate in order to discriminate the minimum inhibitory concentration (MIC) and the liver toxicity of oxothiazole, also, was discerned by injecting 160 mg/kg, 265 mg/ kg and 350 mg/kg doses to mice as well as scrutinizing the liver histopathology.       Results: Derivatives utilized in experiment had no inhibitory effect on Pseudomonas aeruginosa and Klebsiella pneumoniae, though their inhibitory effect was observed on Staphylococcus aureus and Streptococcus agalactiae. For Staphylococcus aureus and Streptococcus agalactiae the diameters of growth inhibition zone were 8.9-22.3 mm and 16.1-25.6 mm, respectively and MIC of 50-200 and 25-100 µg/ml by order. Additionally, by increasing the injection dose of oxothiazole with 160 mg/ml, 265 mg/ml and 350 mg/ml doses, the hepatitis lesions and liver necrosis were observed in experimental mice.        Discussion: The thiazole derivatives possessed more inhibitory trace on gram positive bacteria than gram negative ones. Furthermore, the likely presence of oxygen link to thiazole ring in tested compounds results in the enhancement of inhibitory potency of these substances. Besides, our results suggest that high doses of oxothiazole cause severe liver damage and rapid death less than 24 hours.        Keywords: Thiazole derivatives, Antibacterial effects, Oxothiazole, Liver toxicity.}, Keywords = {Thiazole derivatives, Antibacterial effects, Oxothiazole, Liver toxicity.}, volume = {9}, Number = {4}, pages = {6-14}, publisher = {school of paramedicine, golestan university of medical sciences}, doi = {10.18869/acadpub.mlj.9.4.6}, url = {http://mlj.goums.ac.ir/article-1-772-en.html}, eprint = {http://mlj.goums.ac.ir/article-1-772-en.pdf}, journal = {Medical Laboratory Journal}, issn = {}, eissn = {2538-4449}, year = {2015} } @article{ author = {Ebrahim, Zahra and Tadayon, Keyvan and Mosavari, Nader}, title = {Genomic Characterization of the Vaccinal Strain of Mycobacterium Avium Subspecies Paratuberculosis (MAP) 316F by MIRU-VNTR}, abstract ={Abstract        Background and Objective: Paratuberculosis is a chronic granulomatous enteritis of ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP). this study aimed to characterize the genome of the MAP 316F strain.       Methods: The MAP 316F strain was subjected to the PCR-F57 and PCR-IS900 experiments in order to ensure its identity as MAP.

Fluconazole resistance can be attributed to changes in pathways of sterol biosynthesis, mutation in or overexpression of ERG11 and the expression of CDR1, CDR2, and MDR1. This study aimed to compare the expression of CDR1, CDR2, and MDR1 in C. albicans resistant and susceptible to fluconazole.        Methods: MIC testing for fluconazole was performed on C. albicans isolates isolated from patients with oral and vaginal candidiasis to determine resistant and susceptible strains. Then real time PCR was performed on the resistant and susceptible isolates and the expression of CDR1, CDR2, and MDR1 was compared in C. albicans.      Results: Of 46 Candida albicans isolates, 20 susceptible isolates, 12 semi-susceptible isolates and 14 resistant isolates were identified by MIC. After real time PCR was performed, Candida albicans isolates susceptible to fluconazole showed moderate expression of CDR1, CDR2, and MDR1 genes, while resistant isolates showed slight or no expression.       Conclusion: Increased expression of CDR1, CDR2, and MDR1 had less and insignificant role in resistance to fluconazole.       Keywords: Candida Albicans, Gene Expression, Real time PCR method}, Keywords = { Keywords: Candida Albicans, Gene Expression, Real time PCR method}, volume = {9}, Number = {4}, pages = {33-37}, publisher = {school of paramedicine, golestan university of medical sciences}, doi = {10.18869/acadpub.mlj.9.4.33}, url = {http://mlj.goums.ac.ir/article-1-776-en.html}, eprint = {http://mlj.goums.ac.ir/article-1-776-en.pdf}, journal = {Medical Laboratory Journal}, issn = {}, eissn = {2538-4449}, year = {2015} } @article{ author = {Tavasolian, Fataneh and Abdollahi, Elham and Samadi, Morteza and Vakili, Mahmoo}, title = {Analysis of Hematological and Biochemical Parameters in Methamphetamine Addicts Compared with Healthy Individuals}, abstract ={Abstract         Background and Objective: Methamphetamine has strong stimulating effects on various systems of the human body. The aim of this study was to evaluate the hematological and biochemical parameters in methamphetamine addicts and to compare them with healthyindividuals.      Methods: This is a retrospective case-control study that was conducted in 1390-91 in Ibn Sina Hospital in Shiraz, Iran. Measurement of lipids (cholesterol, triglycerides), liver enzymes (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase), albumin, blood urea nitrogen, creatinine and blood parameters such as platelets and white blood cells(WBCs) count, hemoglobin concentration and hematocrit of 60 individuals addicted to methamphetamine and 60 healthy subjects as a control group was carried out.       Results: Alanine aminotransferase, aspartate amino transferase, alkaline phosphatase, WBCs and platelet count and serum creatinine levels in methamphetamine addicts were significantly higher than the control group(p-value <0.001), while hemoglobin, hematocrit and albumin levels were lower in these patients (p-value <0.001).       Conclusion: The use of methamphetamine increases lipid peroxidation, changes levels of inflammatory markers and increases liver enzymes, which may increase the risk of liver diseases. It also increases WBCs and platelets count as an early sign of inflammatory disease progression, associated with methamphetamine abuse. Decreased hemoglobin and hematocrit can also increase the risk of anemia in these patients.
