Background: This study aimed to compare the efficacy and safety of insulin versus oral hypoglycemic drugs for gestational diabetes treatment, using evidence based medicine approach.

Materials and Methods: This secondary study was conducted by selecting a comprehensive systematic review through searching the Cochrane library. To calculate the number needed to treat (NNT), outcomes such as cesarean section, macrosomia, birth weight more than 90th percentile, operative vaginal delivery, labor induction, post partum hemorrhage, and shoulder dystocia has been considered while neonatal hypoglycemia, NICU hospitalization and fetal distress were considered for calculating number needed to harm (NNH). To calculate the likelihood of helped versus harmed (LHH), macrosomia and hypoglysmia were selected. Data were analyzed with Wilson score test.

Results: The NNT for above outcomes were 3, -14, -5, 16, -3, 31, and 32, respectively. Among them cesarean section was significance. Calculated NNH for side effects were 6, 15, and -17 which only was significance for neonatal hypoglycemia (p<0.05). The LHH was estimated -0.43.

Conclusion: Considering LHH, it seems that the benefit of insulin in management of gestational diabetes is more than metformin. But with respect to issues such as low sample size of trials, lack of assessment the maternal hypoglysemia as complication of insulin therapy, the findings should be considered cautiously.

Background: Considering the increased activity of hypothalamic orexinergic neurons due to morphine administration, and its extensive projections to the hippocampus, it is probable that morphine effect on CA1 neuronal function is mediated by orexinergic system. So the effect of hippocampal orexin-1 receptors (OX1R) blockade on CA1 baseline synaptic response and short term synaptic plasticity was investigated.

Materials and Methods: In this experimental study, animals received morphine 10 mg/kg/12h/(SC) for 10 days. SB-334867-A, OX1R antagonist (0.5&mug/0.5 &mul), was microinjected intrahippcampally for OX1R inhibition before each morphine injection. Baseline synaptic response and short term synaptic plasticity were evaluated by field potential recording. fEPSP was recorded from CA1 following Schaffer collaterals stimulation. After Input/Output construction, short term synaptic plasticity was induced by paired pulse stimulations.

Results: Chronic use of morphine did not affect the baseline synaptic response (p>0.05). SB- 334867-A microinjection in CA1 did not have any effect on baseline synaptic response in morphine dependent rats. Morphine increased paired pulse index (PPI) at 80 ms inter pulse interval (IPI, p<0.05). SB-334867-A pretreatment did not affect this morphine induced PPI change.

Conclusion: The results suggest that orexin-1 receptors (OX1R) do not mediate the effect of morphine on baseline synaptic response and short term synaptic plasticity in CA1 area of the hippocampus.

Background: Acute lymphoblastic leukemia (ALL) is the most common type of cancer in children. Currently, chemotherapy is the most effective method of leukemia cancer treatmentwhich has many side effects. New strategies in cancer therapy utilizecompounds that specifically target aberrant signaling pathways in order to reduce toxic sideeffects Indole-3-carbinl (I3C) found in vegetables has multiple anti-cancer properties because of its ability to modulate multiple cellular signaling pathways. In this study the molecular mechanism of the action of indole-3-carbinol on pre- B ALL cells was investigated.

Materials and Methods: In current study, NALM-6 cells were treated with different concentrations of I3C at specific times. Analysis of cellular DNA content was performed by flow cytometry for evaluation of cell cycle status. The protein expression of p21, p53 as well as c-Myc proteins was determined by Western blot in I3C-treated cells.

Results: Cell cycle histogram analysis showed that I3C significantly increased the percentage of G1 cells compared with non-treated cells (control)(p<0.05). The western blot analysis also indicated I3C significantly up regulated p21, p53 expression and down regulated c-Myc expression (p<0.05).

Conclusion: The G1 arrest induced by I3C is associated with down-regulation of c-Myc and up-regulation of p53 and its downstream target p21.

Background: Hematopoietic stem cell transplants are routinely used to treat patients with cancers and other disorders of blood and immune systems. Osteoblasts constitute part of the stromal cell support system in marrow for hematopoiesis by participating in the formation of the HSC niche. It is believed that interaction between hematopoietic cells and bone forming osteoblasts regulate each other’s function. It is established that acute blood loss in animal models activates bone formation and niche development because of EPO stimulation. In this experimental study we have examined the co-culture of HSCs derived from cord blood which treated with EPO in vitro, on osteoblastic differentiation of mesenchymal stem cells.

Materials and Methods: In this experimental study MSCs isolated from bone marrow and co-cultured with CD 34+ CD38- HSCs isolated from cord blood. These co-cultured cells were treated with different doses of erythropoietin for 14 days, after that RNA were extracted from MSCs and analysed with RT-PCR to evaluate the expression of osteopontin and osteocalcin. Alizarin red and alkaline phosphatase staining were done for osteoblastic differentiation.

Results: Osteopontin and osteocalcin were expressed in MSCs. Cellular staining were positive for osteoblastic differentiation. Differentiated cells expressed osteoblastic markers.

Conclusion: These data suggest that EPO regulates the osteoblastic differentiation from bone marrow MSCs in vitro.

Background: The aim of this research was to determine the relationship between inflammatory markers (Fibrinogen, C-reactive protein (CRP) and Creatine kinase (CK)) and respiratory responses FEF25-75% (Forced expiratory flow in 25-75 percent) and FEV1 (Forced expiratory volume in one second) in 14-16 year’s Urmia city boys in response to an incremental physical activity.

Materials and Methods: The subjects were boys of 14-16 years among 24 healthy participants. These groups divided into two groups randomly, one group as trained one (n=12) and the othes as control group. Blood sample was taken in baseline and after Modified Balke Protocol in trained group, And the blood sampling was taken in baseline and 48 hours later in control group. respiratory responses were measured immediately after Modified Balke Protocol.

Results: CRP and Fibrinogen significantly increased in trained group (p<0.001) and this group had high level of these markers compared with control group (p<0.001). The association between CRP with FEF25-75% and fibrinogen with FEF %25-75 and CK with FEF 25-75% in trained group was significant (p&le0.05).

Conclusion: The results of this study show that incremental physical activity increased inflammatory factors in active children. Incremental exercise shows a strong relationship between some inflammatory markers and respiratory parameters in adolescents 14-16 years old.

Background: The current paper set out to investigate the level of asbestos fiber and asbestos body in sputum and assayed of haematological factors, liver enzymes and pulmonary function test in asbestos exposed group.

Materials and Methods: An analytical cross-sectional study was conducted with a total number of 100 subjects. The case group included 50 male workers with the age range of 25-60 who had at least worked for five years in the asbestos-cement factory. Control subjects consisted of 50 people who had no history of occupational exposure to asbestos. Lung function tests were measured with a portable calibrated vitalograph-PFT spirometer. liver enzymes were assayed with Pars Azmoon kits. Counts of red blood cells and white blood cells were assayed with a cell counter. We used light polarizan microscope to study the level of asbestos fiber and asbestos body in sputum.

Results: Asbestos fiber observed in sputum sample of workers and type of asbestos fiber is chrysotile. Asbestos bodies were found in only 10% of the workers. Decrease (but not significant) in lung function factors (FVC, FEV1, FVC/FEV1) had been seen in the workers in compare with control group. WBC, Eosinophil, neutrophil, lymphocyte, monocyte and liver enzymes levels were significantly higher (but in normal range) in workers as compared with the control group.

Conclusion: Presence of asbestos fiber and asbestos body in workers sputum samples showed workers exposure to asbestos and reduced level (insignificant) of lung function factors and increased level of leukocyte may be indicated pulmonary inflammation. These results also suggested that occupational exposure to asbestos dust may perturb liver mal function parameters

Background: Spinal anesthesia is an efficient method of providing intra operative analgesia and a safe alternative to general analgesia in many cesarean patients. Despite its advantages, SA is not free from adverse effects, which include unwanted cardiovascular events, in most cases: hypotension and bradycardia. Ondansetron is a 5HT3 receptor antagonist, with known efficacy on preventing nausea and vomiting. Maybe ondansetron given intravenously attenuates the fall of blood pressure and heart rate, by 5HT3 blocking in vagal nerve endings and effect on BJR.(Bezold jarish Reflex).

Materials and Methods: In this clinical trial 102 healthy pregnant women that were candidate for elective cesarean in hamedan fatemieh hospital during 3 months in 1390, studied. They were randomized into 2 groups: the ondansetron group, n= (51) received (4miligram) ondansetron intravenously before performing spinal anesthesia, and placebo group n= (51): received 2cc sterile water before spinal anesthesia. Spinal anesthesia was performed with hyperbaric bupivacaine (0.5%) 10 mg and sufentanil (5 µg) BP and HR were measured and recorded before and after anesthesia immediately. If hypotension happened, ephedrine 5- 10mg injected. Itching and nausea recorded every 10 min during operation by observation and question.

Results: There were no significant differences in SBP, DBP, MAP, HR and itching in both groups. Nausea and vomiting ,and mean consumed ephedrine was siginificantly different in both groups.(p=0.001, p=0.009).

Conclusion: Ondansetron given intravenously with antiemetic dose (4miligram), decreases mean consumed ephedrine and nausea and vomiting after spinal anesthesia, but doesn't have an influence on BP, HP and pruritus

Background: Some children have abrupt onset of severe urinary frequency, voiding as often as every 10-15 min during the day, without dysuria, UTI, daytime incontinence, or nocturia. The most common age for these symptoms to occur is 4-6 yr, after the child is toilet trained, and the vast majority are boys. This condition is termed the daytime frequency syndrome of childhood or Pollakiuria. The condition is functional no anatomic problem is detected. The symptoms occur often just before a child starts kindergarten or if the child is having emotional family stress-related problems. OCD is a chronically disabling illness characterized by repetitive, ritualistic behaviors over which the patient has little or no control. OCD has a lifetime prevalence of 1-3% worldwide, and as many as 80% of all cases have their onset in childhood and adolescence. The purpose of this study was to investigate the relationship between OCD and Pollakiuria.

Materials and Methods:In this case-control study, we evaluated (152) children aged 6-18 years old who were visited in the pediatric clinics of Amir-Kabir Hospital, Arak, Iran. The control group considered of (76) healthy children and the case group included (76) age and sex matched children with Pollakiuria. Then, the children’s behavioral status was evaluated using the children’s Yale-Brown Obsessive-Compulsive Scale (C-YBOCS). The C-YBOCS is helpful in identifying children with OCD. The data was analyzed using descriptive and analytical statistics in SPSS-16.

Results: OCD was detected in (5) case (6.6%) with Pollakiuria and (8) controls (10.5%). The difference in OCD was not significant (p-value 0.282) between the two groups.

Conclusion: OCD isn’t more common in Pollakiuria versus non-Pollakiuria children. It is recommended to conduct a study with higher sample volume in order to detect the relationship between OCD and Pollakiuria.

Background: This study aimed to examine the antibacterial effect of Polyamidoamine-G4 dendrimer on Escherichia coli, Enterobacter cloacae, Bacillus subtilis and Staphylococcus aureus.

Materials and Methods: In this experimental study, the antibacterial effects of Polyamidoamine-G4 dendrimer were studied by disc diffusion and micro-dilution method. Different concentrations of Polyamidoamine-G4 inoculated onto blank disks and were placed in Mueller-Hinton agar media. Zone of inhibition was investigated by bacterial inoculation according to the McFarland standard 0.5. Minimum inhibitory concentration and minimum bactericidal concentration of Polyamidoamine-G4 dendrimer were determined by micro-dilution method in nutrient broth culture.

Results: Zone of inhibition in concentration 500 &mug/ml of Polyamidoamine-G4 dendrimers for Escherichia coli, Enterobacter cloacae, Bacillus subtilis and Staphylococcus aureus were 14, 0, 35 and 29mm, respectively. Concerning the Zone of inhibition in gram negative bacteria with gram positive ones was p<0.05 and had significant difference. The minimum inhibitory concentration of Polyamidoamine-G4 dendrimer for Escherichia coli, Bacillus subtilis and Staphylococcus aureus were 1250, 2.5, and 1 &mug/ml, respectively. The minimum bactericidal concentration of Polyamidoamine-G4 dendrimer belonged to Escherichia coli, Bacillus subtilis and Staphylococcus aureus were 2500, 5 and 5 &mug/ml, respectively. Polyamidoamine-G4 dendrimer had not bacteriostatic and bactericidal effects on Enterobacter cloacae.

Conclusion: According to the results, Polyamidoamine-G4 dendrimer can eliminate Escherichia coli, Staphylococcus aureus and Bacillus subtilis effectively. It is suggested in the rest of this study that the probable toxicity of nanostructured compounds examined in drinking water and, economic studies is done for synthesis and their applications in case of prevention of using.

Background: Delivery of antigens directly to dendritic cells enhances the immune responses to the antigen and is an attractive approach for eliciting cellular immune responses against mutagenic pathogens like HIV virus. So the aim of this study is evaluation of immune responses elicited by delivered multi-epitopic HIV-1 tat/pol/gag/env recombinant protein to dendritic cells in sito using &alphaDEC-205 mAb.

Materials and Methods: In this study, recombinant protein expressed by pET23a-HIVtop4 plasmid including HIVtop4 sequence (Gag158-186, Pol150-190, ENV296-323, ENV577-610, Tat1-20 and Tat44-61) in BL21 E. coli cells was used as vaccine model. To exploiting dendritic cells, properties for immunization purposes, we conjugated this recombinant protein chemically to anti body against DEC-205 receptor on these cells. Balb/c mice immunized subcutaneously (s.c.) with conjugated multi-epitopic protein or un-conjugated one (as control) simultaneously with Poly I: C as dendritic cell maturation factor. Lymphocyte proliferation was measured by bromo di uridine assay, Cytotoxicity by Grenzyme B production activity, IL-4, IL-17, IFN- cytokines production and total antibody by direct and indirect ELISA methods in order.

Results: Immunization by anti DEC-205 conjugated peptide led to a significant increase in the proliferative responses of lymphocytes, production of Gr-B, IFN-&gamma, IL-4 and IL-17 cytokines and total antibody titer in comparison with the none targeted groups.

Conclusion: It is concluded that targeting of protein antigens to DEC-205+dendritic cells significantly enhances immune responses in compare to non-targeting strategies.

Background: Gestational diabetes mellitus (GDM) is defined as glucose intolerance with first dignosis during pregnancy. There is some evidence indicating that chemerin play a role in the development of GDM. In this study, for the first time, a possible association of rs17173608 polymorphism in the chemerin gene with the risk of GDM in Arak population was investigated.

Materials and Methods: In this case-control study, 120 GDM and 150 pregnant women with normal glucose tolerance were selected. GDM was confirmed by oral glucose tolerance according to the new IADPSG criteria. Genomic DNA was extracted from EDTA treated whole blood. The polymorphism of chemerin gene was determined using tetra-amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR).

Results: The genotype frequencies of  TT, GT and GG at rs17173608 were respectively 81.7%, 17.5% and 0.8% in the GDM group and 73.3%, 25.3% and 1.3% in the control group. There were no statistical differences in genotype frequencies between case group and the control group. Also, allele frequencies in the GDM group  (T 90.4% , G 9.6%), did not differ significantly from the control group ( T 96% ,G 14%). No association was found between genotype frequencies and FBS, 1h, 2 h and BMI.

Conclusion: The present study show that the rs17173608 polymorphism in the chemerin gene is not associated with the development of glucose intolerance and GDM in the studied population.

Background: Menopause is a critical period in the women life which is associated with different neurophysiological and cognitive changes. This study aimed to determine the relationship between menopausal symptoms with metabolic syndrome in postmenopausal women.

Materials and Methods: This descriptive - analytical study was conducted on 165 postmenopausal women referred to health centers in Ahvaz. Data collection tools were standardized questionnaire menopausal rating symptoms (MRS), questionnaire to record demographic information and the results of experiments and measurements (blood pressure, Waist circumference). The data were analyzed by Pearson correlation coefficients, Mann-Whitny in by SPSS version 19.

Results: The results showed that the overall mean of MRS in this study was 11.85±5.4. The mean of metabolic syndrome was 36±4.8 percent and we found significant association between blood pressure (p=0.04), blood sugar (p=0.02),HDL-C(p=0.02) and urogenital symptoms. But there werent significant relationship between other metabolic syndrome components and other menopausal symptoms (somatic and psychological Dimensions).

Conclusion: The relationship was observed between metabolic syndrome and urogenital symptoms, therefore, as a preventative health strategy women with urogenital complaints should examin for metabolic syndrome.

Background: The outbreaks of new antigenic variants of influenza viruses in human populations have increased necessity the improvement of controlling programs. Influenza vaccines are formulated with adjuvant to enhance and direct the host immune responses. Currently, much effort is devoted to designing molecular adjutants. Hemokinin-1 (HK-1) activates T and B cells for proliferation, survival, differentiation into plasma cells, and antibody production. In this study, the effect of HK-1 as a molecular adjuvant for inducing humoral immune response against influenza virus was investigated.

Materials and Methods: The HK-1 coding sequence was cloned into pcDNA3.1 vector and used as adjuvant. Groups of mice were immunized with an inactivated influenza vaccine formulated with HK-1. The sera of vaccinated mice were collected prior to priming and boosting injections and at defined weeks, and analyzed with serological assays.

Results: The results showed that HK-1 was able to increase antibody titer against virus vaccine. The mice immunized with the adjuvanted vaccine produced higher antibody titers against influenza comparing to vaccine alone immunized group. Number of boosting had no effect on the enhancing of antibody titer.

Conclusion: These data revealed that HK-1 as a molecular adjuvant induces stronger humoral and memory responses against influenza immunization.

Background: Catamenial recurrent pneumothorax is spontaneous pneumothorax in women of reproductive age, which includes 1-30% of spontaneous pneumothoraces in women and is associated with the menstrual cycle.

 Case: A 39-year-old woman with sudden onset dyspnea, respiratory distress and decreased right side respiratory sounds with a history of spontaneous pneumothorax and chest tube placement one month ago. The patient's symptoms improved after chest tube placement and within less than 24 hours after onset, she began menstruating. Treatment was performed with chemical pleurodesis with tetracycline and oral danazol.

Conclusion: Catamenial pneumothorax and thoracic endometriosis should be considered in all women of childbearing age with spontaneous recurrent pneumothorax. Early detection of this syndrome can result in reduction of morbidity and mortality with recurrence episodes.

Background: Heart failure with normal ejection fraction (HFNEF) is commonly seen in adults. It is possible that old patients with HFNEF have severe clinical status. The aim of current study is to evaluate clinical and echocardiographic findings in old patients compared to young patients with HFNEF.

Materials and Methods: In this cross-sectional analytical study, 126 patients with HFNEF were evaluated in two groups of patients &ge60 years old (n=52) and <60 years old (n=74) for demographic, clinical and echocardiographic findings.

Results: Patients &ge60 years old had significantly more hyperlipidemia, less hypertension and more FC II. Patients &ge60 years old also had significantly larger septal wall thickness, lower end diastolic and systolic volume, end systolic diameter, E/A ratio and septal E’, lower diastolic dysfunction grade, higher left ventricle ejection fraction, left atrial volume index, E/E’ ratio and deceleration time compared to patients <60 years old.

Conclusion: Old patients with HFNEF have different clinical and echocardiographic findings compared to younger patients which are indicative of the disease severity in some cases. So, exact evaluation of the patients could be helpful in early diagnosis of these patients and providing an adequate treatment.

Background: Rheumatoid arthritis is an inflammatory disease. Hypertension could occur as a result of chronic inflammation in RA patients. Some evidence demonstrates anti-inflammatory effects of alpha-lipoic acid in inflammatory diseases. However, a limited number of studies have evaluated the effects of alpha-lipoic acid in rheumatoid arthritis. Therefore, the current study was designed to investigate the effects of alpha-lipoic acid supplementation on blood pressure and some inflammatory factors.

Materials and Methods: The present study was a randomized, double-blinded, placebo-controlled clinical trial in which 70 female patients aged 20–50 years were randomized to two groups to receive either alpha-lipoic acid (1200 mg/day) or placebo. The intervention duration was 8 weeks. Systolic and diastolic blood pressures were measured before and after the supplementation period. Also, C-reactive protein (CRP) and interleukin-6 (IL-6) were measured. Statistical analysis was done using SPSS13 software.

Results: 65 RA patients completed the trial. Systolic and diastolic blood pressure in alpha-lipoic acid group was significantly decreased in comparison with placebo group (p<0.05). But, CRP and IL-6 serum levels did not indicate any significant within- and between group changes.

Conclusion: In the present study, alpha-lipoic acid supplementation resulted in significant blood pressure reduction in rheumatoid arthritis participants.

Background: Allergic rhinitis, a chronic inflammatory disease of the respiratory tract, includes an IgE-mediated inflammatory response in the mucosal region of the aerial tubles. Since IL-8 plays a role in increasing the amount of immunoglobulin E and serves as an effective factor in the prevalence of this disease, so this study aims to investing at that whether IL-8 genotypes of 133 C/G polymorphism is associated with the amount of immunoglobulin E in serum in patients with allergic rhinitis.

Materials and Methods: In this analytical and descriptive study, by investigating 130 patients with AR and 62 healthy control volunteers in Chahar Mahalo Bakhtiari province, total level of IgE in serum was determined by ELISA method and then its association with 133 C/G polymorphism was investigated. T-test and chi-square statistical analyzes were performed using SPSS software for statistical analyses.

Results: the total serum IgE level of the patients with GC genotype of 133 C/G SNP were significantly higher regarding normal individuals (p<0.05).

Conclusion: The sigmificant relationship between 133 C/G genotype in IL-8 P gene promoter and increased serum IgE level confirms tht it plays a role in the prevalence of AR.

Background: Estrogen hormone regulates cell proliferation in breast tissue physiologically. Evidences show that changes in estrogen signaling pathways, including the receptor alpha (ER&alpha), happen during breast cancer progression. ER&alpha is expressed in most breast tumors and its association with the development of low-grade tumors has been demonstrated. Single nucleotide polymorphisms (SNPs) in genes may differ in susceptibility to cancer and result in different respond to treatment in different populations. The present study aimed investigated the association between single nucleotide polymorphisms (rs2234693: C/T) in gene ESR&alpha in patients with breast cancer.

Materials and Methods: In this case-control study 150 women with breast cancer and 142 healthy women without a family history of breast cancer were enrolled. DNA was extracted from blood samples. After primer design, technique of PCR-RFLP was used and samples were genotyped by acrylamide gel electrophoresis. Statistical analyzes were performed using SPSS version 20 and chi square test and Final findings were specified.

Results: TT and CT genotypes for ra2234693: C/T site compared with the CC had 5.5 and 1.5-fold increased risk respectively. Statistically significant differences were found between cases and controls for fibrocystic disease and age at menarche.

Conclusion: We not found an association between C/T polymorphism and breast cancer. But CC and TT genotypes of this polymorphism in estrogen receptor alpha gene related with breast cancer that are consistent with the findings of some other researchers.

Background: Nowadays, the decline in birth rate is one of the most important social problems in developing societies. Infertility is defined as a failure to conceive in a couple trying to reproduce after one year of regular intercourse without contraception. Leptin have been implicated in maintaining normal female reproductive functions, including lactation, folliculogenesis, ovarian steroidogenesis, the maintenance of mammary gland morphology, the development of dominant follicles and oocytes, the maturation of the uterus endometrium, and menstrual cycle regulation. Sinyle-nucleotide polymorphism T>C found in exon 3 leads to substitution of Arg>Trp at codon 1.5 (R105W). In this case-control study, we aimed to evaluate the association of this polymorphism and the risk of female infertility in the population of Guilan.

Materials and Methods: Blood Samples were collected from 86 patients diagnosed with female infertility and 60 control subjects, and genotyped by allele-specific PCR (AS-PCR). To estimate the association between genotype and allele frequencies in cases and controls, Chi-Square analysis was used.

Results: Analysis revealed no significant differences were found in genotype and allele distributions of LEP Arg105Trp between infertility cases and controls (p=0.21, p=0.2) in this population.

Conclusion: Our findings indicated no significant association between the Arg105Trp polymorphism and female infertility risk (p=0.21). While, more studies are needed to confirm the results.

Background: In 1970, human papillomavirus (HPV) was introduced as the main etiologic factor of cervical carcinoma. Since there is no possibility of detecting the virus and its subtypes using serological methods and cell culture, the molecular methods such as PCR have particular importance in accurate, early and definite diagnosis of the virus. So, in this research, our goal is to use a proprietary PCR assay based on L1 gene of human papillomavirus for molecular recognition of HPV and to evaluate its prevalence in patient samples.

Materials and Methods: In this experimental study, after collecting of samples from malignant cervical lesions, the viral DNA was extracted from paraffin blocks of 50 clinical samples and PCR was done by specific primers for L1 gene of human papillomavirus in all samples. After the analysis of PCR products by 2% agarose gel electrophoresis, sensitivity and specificity of the test were also evaluated.

Results: Among 50 patient samples, 33 cases were confirmed to be positive for HPV infection and 17 cases were negative, showing high frequency of HPV in this patient population (about 66%). The results of specificity assay were positive for papilloma samples and sensitivity of the assay was 20 copies of recombinant construct containing L1 per reaction.

Conclusion: This study showed that PCR by specific primers for L1 gene of human papilloma virus is a proper and accurate method for detection of this virus and the results confirm the previous reports of correlation between HPV and cervical carcinoma.
