Zare MirakabadiRazi Vaccine & Serum Research InstituteJournal Article20160112Scorpionism is a known significant problem of medical and social importance in many tropical and subtropical regions including the Middle East. In Iran, highest prevalence of scorpion sting about 60% of all the stings has been reported from Khuzestan province. Among the 21,000 cases of reported scorpion stung patients, 12% were caused by H. lepturus, but contributed to 95% of all moralities in scorpion stung patients. The sting of H. lepturus does not produce an immediate pain as does the sting of other scorpions, rather cause delayed swelling that may diffuse and is often accompanied by late necrosis at the sting site suggestive of less significant role of the nervous system stimulation. Since the venom from H. lepturus is cytotoxic in nature and the renal response and blood toxicity are normally simultaneously manifested, it is suggested that the toxin binds to kidney tissue and potentially induce acute renal failure in stung patients. Pharmacokinetic analysis revealed that Intramuscular) i.m) injection of antivenoms is ineffective in neutralizing the action of venoms. Although some reports mention the slow distribution rate of H. lepturus venom following sting, but since the cytotoxic effect of venom from this scorpion is irreversible by antivenom once it occurs, it is recommended to use antivenom through intravascular (i.v) route. Antivenoms of F(ab)2 fraction are the best choice of treatment for their fast extravasation, their ample distribution into the extracellular space, and their prolonged retention time.https://archrazi.areeo.ac.ir/article_103916_7b96fe478fdf23da14f92bbc1ebb8063.pdfRazi Vaccine & Serum Research InstituteArchives of Razi Institute0365-343968220131101Molecular detection of Acute Bee Paralysis Virus in Iranتشخیص مولکولی ویروس فلجی حاد زنبور عسل در ایران10110410391710.7508/ari.2013.02.002ENMojtaba Moharramiموسسه تحقیقات واکسن و سرم سازی رازیH.

If not inactivated properly, cellular and/or environmental DNA nucleases will degrade genomic material during the extraction stage, and therefore might give rise to incorrect results in PCR experiments. When crude cell extracts, proteinase K–treated templates and purified DNAs prepared by phenol-chloroform-isoamylalcohol method as well as a commercial extraction kit were subjected to the Salmonella enterica Enteritidis specific STM2 PCR, with exception of crude cell extract, PCR products from all other three methods saved their integrity for 28 days post-generation. This work aimed to find out whether improvement to boiling method can guaranty stability of PCR products. As results showed, treatment of crude cell extracts from S. Enteritidis with proteinase K offers an inexpensive, fast and effective DNA extraction method suitable for high-throughput laboratories.https://archrazi.areeo.ac.ir/article_103918_ae65ffd3ee668490a52d051b31423f86.pdfRazi Vaccine & Serum Research InstituteArchives of Razi Institute0365-343968220131101Amplification, cloning and expression of Brucella melitensis bp26 gene (OMP28) isolated from Markazi province (Iran) and purification of Bp26 Proteinتکثیر، کلونینگ و بیان ژن bp26( OMP28) بروسلا ملیتنسیس بومی استان مرکزی و تخلیص پروتئین BP2611111610391910.7508/ari.2013.02.004ENH.

The aim of this study was sequencing Iranian M. synoviae isolates for the detection of nucleotide variation in the M. synoviae vlhA gene. Using oligonucleotide primers complementary to the single-copy conserved 5´ end of vlhA gene, amplicons of ~400 bp were generated from 10 M. synoviae isolated from commercial broiler chicken farms in Iran, afterward the conserved domain of the vlhA gene of M. synoviae was sequenced and analyzed for Iranian isolates. The results showed that, there was a complete concordance between all Iranian isolates nucleotide sequence (1-386 nt). In comparison with vaccine MS-H strain sequence, all Iranian isolates; entire vlhA sequence downstream of nucleotide 386 was different. It was also observed in all Iranian M. synoviae isolates, point mutations and frame-shift mutation. This study was demonstrated a difference between Iranian isolates and live commercial vaccine MS-H strain. Furthermore, these data indicated that changes in the vlhA gene sequence could introduce into the expressed vlhA gene amino acid codons and effective in pathogenesis rate in flocks.https://archrazi.areeo.ac.ir/article_103920_6aff864dce3fef0f118805f3c230657f.pdfRazi Vaccine & Serum Research InstituteArchives of Razi Institute0365-343968220131101Molecular survey of Canine Microfilariae Species in East-Azerbaijan province of Iranبررسی مولکولی میکروفیلرهای سگ سانان در منطقه آذربایجان شرقی12512910392110.7508/ari.2013.02.006ENH.

Because of importance of this infection in veterinary medicine and public health, it is necessary to carry out an epidemiological and cross sectional studies in various geographical areas and use of well-adapted diagnosis methods. In this study 205 capillary and whole blood samples were collected from doges in various counties of East-Azerbaijan province. Samples after preparation were examined by Knott`s test and light microscope for presence of microfiler. In molecular identification, Pan-filarial and species-specific PCR perimers was used to differentiate among Dirofilaria immitis, Dirofilaria repens, Acanthocheilonema reconditum, Acanthocheilonema dracunculoides, Brugia malayi and Brugia pahangi. Descriptive statistics were used for data analysis. Total infection prevalence with the microscopic evaluation was 77 (37.5 %) and in PCR test was 94 (45.8 %). The most common species of canine filarial parasite identified in this study was D. immitis 54 (57.4 %) followed by Acanthocheilonema species 40 (42.6 %). The molecular evidence on the sequence of the ITS-2 region provided strong evidence that the canine microfilariae discovered in this study belong to a novel species of Acanthocheilonema. Information about infection prevalence helps us to improve disease management practices in the studied area, apply new hygiene policy and reduce extra costs of therapeutic agents and PCR is a quick and accurate molecular genetics method for detection of filarial species.https://archrazi.areeo.ac.ir/article_103921_d6d7172f2d4180cc82250d847f024661.pdfRazi Vaccine & Serum Research InstituteArchives of Razi Institute0365-343968220131101HA03 as an Iranian Candidate Concealed Antigen for Vaccination against Hyalomma anatolicum anatolicum: Comparative Structural and In silico StudiesHA03 بعنوان یک کاندیدای آنتی ژن مخفی ایرانی برای واکسیناسیون علیه کنه هیالوما آناتولیکوم آناتولیکوم13113810392210.7508/ari.2013.02.007ENH.

ForoghiJournal Article20160112In the last decades researchers had focused on developing a vaccine against tick based on protective antigen. Recombinant vaccines based on concealed antigen from Boophilus microplus have been developed in Australia and Cuba by the name of TICKGARD and GAVAC (De La Fuente and Kocan, 2006). Further studies on this antigen have shown some extent of protection against other species (De Vos et al., 2001). In Iran most important species is Hyalomma anatolicum and limited information about its control are available. This paper reports structural and polymorphic analysis of HA03 as an Iranian candidate concealed antigen of H. a. anatolicum deposited in Gen-Bank .(Aghaeipour et al. GQ228820). The comparison between this antigen and other mid gut concealed antigen that their characteristics are available in GenBank showed there are high rate of similarity between them. The HA03 amino acid sequence had a homology of around 89%, 64%, 56% with HA98, BM86, BM95 respectively. Potential of MHC class I and II binding region indicated a considerable variation between BM86 antigen and its efficiency against Iranian H. a. anatolicum. In addition, predicted major of hydrophobisity and similarity in N-glycosylation besides large amount of cystein and seven EGF like regions presented in protein structure revealed that value of HA03 as a new protective antigen and the necessity of the development, BM86 homolog of H. a. anatolicum HA03 based recombinant vaccine.https://archrazi.areeo.ac.ir/article_103922_272de3ed3a0ea30618fb2ec773b54555.pdfRazi Vaccine & Serum Research InstituteArchives of Razi Institute0365-343968220131101Design and evaluate alginate nanoparticles as a protein delivery systemطراحی، ساخت و ارزیابی نانوذرات آلژینات به عنوان سیستم انتقال پروتئین13914610392310.7508/ari.2013.02.008ENS.

InanlouJournal Article20160112In recent years, encapsulation of drugs and antigens in hydrogels, specifically in calcium alginate particles, is an interesting and practical technique that was developed widespread. It is well known that alginate solution, under proper conditions, can form suitable nanoparticles as a promising carrier system, for vaccine delivery. The aim of this study was to synthesis alginate nanoparticles as protein carrier and to evaluate the influence of various factors on nanoparticles properties. Alginate nanoparticles were prepared by ionic gelation method. Briefly, various concentrations of CaCl2 were added to different concentrations of sodium alginate dropwisly by homogenizing magnetically at 1300 rpm. The effects of homogenization time and (-) rate were investigated on nanoparticle feature. Nanoparticles were characterized for their morphology and size distribution. Evaluation of loading capacity and loading efficiency of nanoparticles were performed by using various concentration of BSA. The concentration of 0.3%w/v sodium alginate and 0.1%w/v CaCl2 solution, homogenization time 45 min and homogenization rate 1300 rpm were observed as suitable condition - to prepare optimized nanoparticles. It can be concluded that the properties of nanoparticles are strongly dependent on the physicochemical conditions. The optimum concentrations of alginate and CaCl2and appropriate condition led to forming desirable nanoparticles that can be used as carrier for drug and vaccine delivery.https://archrazi.areeo.ac.ir/article_103923_9d0b1051ebef2aedfb007693222c82a4.pdfRazi Vaccine & Serum Research InstituteArchives of Razi Institute0365-343968220131101Enhancement of NMRI Mouse Embryo Development In vitroبهبود تکوین رویان موش نژاد NMRI در شرایط آزمایشگاهی14715210392410.7508/ari.2013.02.009ENM.
