Abstract
Abstract Background and objectives: Infection has a Leading role in pregnancy. Cytomegalovirus (CMV), listeria and Toxoplasma are the most common causes of infection in human. Based on the previous researches, about 15-25 percent of being infected during pregnancy leads to some complications such as abortion, fetal death, early labor and etc. This study was designed to determine the seroprevalence of Cytomegalovirus (CMV), Toxoplasma gondii and Listeria moncytogenes among pregnant women in Gorgan, north of Iran (2005-2006). Material and Methods: we conducted this Simple randomized study on 118 unsuccessful pregnant woman and 99 successful ones referred to Deziani hospital in Gorgan. We assayed both IgG and IgM antibodies for CMV and Toxo by Elisa and IFA method for Listeria. In addition, we fill out a Check list and then use SPSS soft ware, chi square to analyze the data. Results: The frequency of IgG for CMV and Toxo is 89.9% and 45.5% in successful pregnant women and 77.1% and 44.1% for unsuccessful pregnant women (P=0.41, P=0.01). IgM frequency for CMV and Toxo is 14.1% and 46.5% in successful women and 30.5 and 21.7% in unsuccessful ones. (P=0.003, P=0.002)Total frequency (IgG, IgM) for Listeria is 7.62% and %3.03 in successful and unsuccessful women, respectively. There is a significant relation between abortion and IgM titer against Toxoplasma in successful and unsuccessful groups. (P=0.003).This relation is true for total antibody titer against Listeria (P=0.003). Conclusion: Because of high titer of antibodies against CMV, Toxo and Listeria in unsuccessful pregnant women, suffering from these agents during pregnancy may result in abortion and fetal death. Hence, we recommend to hold some preventive and educational program and also to assay antibodies against theses agents.

Abstract
Abstract Background and objectives: Giardiasis is a parasitic infection of small intestine, with a worldwide distribution and the prevalence of Giardia in different parts of the world varies between 1 to 25%. Plants have the vast range of antimicrobial and antifungal activity that can be identified as alternative treatments for bacterial and parasitic pathogens, the same as Giardia. In this study, the methanol extracts of eucalyptus plants, Satureia hortensis and Heracleum glabrescens, on Giardia cysts were studied in vitro. Material and Methods: The cysts were isolated from the feces using a modified Bingham. After counting by Hemusytumetr, they were placed near by 200 mg / ml, 100 mg / ml and 10 mg / ml of the extracts prepared by DMSO for 30 and 60 minutes. Then, the number of dead and live cysts was counted under a microscope. Results: the fatality effect of the extracts in 60 minutes is higher than those of 30 minutes. The methanol extracts of Satureia hortensis, Eucalyptus and Heracleum glabrescens with the dilution of 200 mg/ml in 60 mins have the fatality effect of 84/3%, 63/3% and 44%, respectively. The highest fatality(84.3%) on Giardia cysts is related to Satureia hortensis with the dilution of 200 mg/ml in 60 mins and the Lowest(27%) is related to Heracleum glabrescens with the dilution of 10 mg/ml in 30-minute period. The significant relationship between the plant type and the fatality of methanol extracts is observed. Conclusion: the methanol extracts of Eucalyptus, Heracleum glabrescens and especially Satureia hortensis have anti-parasitic effects in the laboratory conditions. Thus, they can be used in the future, instead of the chemical antiparasitic drugs. Key words: Antibacterial Giardia lamblia cysts, Eucalyptus, Satureia hortensis, Heracleum glabrescens, Tonekabon

Abstract
Abstract Background and Objective: Along with antibiotics, the use of biological methods to combat bacteria is notably considered. A natural barrier such as amniotic membrane is one of the ways of dealing with bacterial infections. The aim of this study was to determine the antibacterial effect of human amniotic membrane. Materials and Methods: This descriptive study was performed in Dezyani teaching Hospital of Gorgan University of Medical Sciences, Iran. To evaluate the antibacterial activity against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli bacteria, 20 amniotic membranes were obtained from postpartum mothers and examined by repeated dilution, diffusion and extraction techniques. Data were collected by observation method and described by mean and standard deviation. Results: The antibacterial activity was found in 15% of the samples against Staphylococcus Aureus and Pseudomonas aeruginosa, while no antibacterial activity was found against E. coli. Given the 15% positive responses, "Diffusion" and "repeated dilution" techniques were more effective in investigating the antibacterial effect of amniotic membrane. Conclusion: The results show the probability of antimicrobial effect of amniotic membrane tissue and it seems that this property can be affected by many factors.

Abstract
Background and Objective: Normal hemoglobin (Hb) is formed of a heme group and a protein group known as globin. Globin is made of four polypeptide chains and in hemoglobinopathies, the structure of one of these four polypeptide chain becomes abnormal. Cellulose acetate method is a common way to differentiate haemoglobinopathies. Inability to identify the components of Hb low concentrations and incapability to isolate all Hb types are among the disadvantages of this method. The aim of this study was to report the prevalence of hemoglobinopathies in the North of Iran by capillary electrophoresis method.
Methods: All patients with suspected hemoglobinopathies, referred by physicians for electrophoresis, have been studied in a private center in the city of Gorgan, Iran. The level of HbA2, HbA, HbF and other Hb was recorded.
Results: Overall, 725 blood samples were analyzed using the capillary method. HbE was reported in 2 patients, HbH was observed in 2 patients and Hb Barts was reported in 3 patients. Using the capillary method, among patients with the SDG area, only 4 of 38 (10.52%) had HbS and the majority of them (89.48%) had HbD.
Conclusion: HbD is the most common hemoglobinopathy in the North of Iran.

Abstract
Background and objective: Hepatitis B virus (HBV) is a DNA virus with high tendency toward hepatic tissue. There are currently about 3 million HBV-infected people and 350 to 400 million chronic carriers of this virus in the world. X protein plays a role in the over-expression of oncogenes, carcinogenicity of liver cells and overlaps with the basal core promoter of the virus. Mutations at specific nucleotides of this region increase viral replication and liver disease progression. The aim of this study was to investigate the frequency of mutations at nucleotides 1762, 1764 and 1766 of HBV X gene in patients with chronic hepatitis B and hepatitis B-related cirrhosis.
Methods: In this study, 102 patients including 68 chronic hepatitis patients and 34 patients with hepatitis B-related cirrhosis were enrolled. After DNA extraction, HBV X gene was amplified and sequenced using Semi Nested-PCR. Obtained gene sequences were compared with the standard sequence of HBV virus X gene available in the gene bank (Okamoto AB033559). Then, the mutations in the gene X of HBV were identified.
Results: Comparison of the standard sequence with sequences obtained from patients showed the presence of A1762T / G1764A mutation in 12 chronic (17.64%) and 13 cirrhotic (38.23%) patients. Also, C1766G / G1764T mutations were found in 8.23% of chronic patients and 17.64% of cirrhotic patients.
Conclusion: A1762T / G1764A mutations in the overlapping region of the basal core promoter with gene X C-terminal may lead to liver disease progression from chronic hepatitis to cirrhosis, by changing the amino acid sequence of the X protein.

Abstract
ABSTRACT
Background and Objective: Esophageal cancer is the third most common type of cancer in Iran. Studies on water, soil, grains, waste and sediments in Golestan Province have shown that the environmental concentrations of antimony and strontium are increased in areas with high incidence rate for cancer. The carcinogenic effects of strontium have been reported, but carcinogenicity of antimony is still unclear. Since there is not enough information regarding the relationship between the concentration of strontium and antimony and prevalence of esophageal cancer in the province, this study aimed to evaluate serum levels of these elements in patients with esophageal cancer using atomic absorption spectroscopy.
Methods: This study was performed on 30 patients with esophageal squamous cell carcinoma and 30 healthy matched controls. After sampling, concentrations of strontium and antimony were measured using atomic absorption spectroscopy.
Results: Half of the esophageal cancer patients and control participants were male. The mean age of patients and controls was 66 ± 13 and 64 ± 8 years, respectively. The mean serum concentration of strontium in patients and controls was 24.18 ± 1.62 and 24.08 ± 1.46 μg/L, respectively. The mean serum concentration of antimony in patients and controls was 18.61 ± 1.48 and 18.98 ± 1.93 μg/L, respectively. No statistically significant difference was observed between the serum concentrations of the two elements in patients and controls.
Conclusion: There is no difference between serum levels of strontium and antimony in cancer patients and healthy controls, which could be due to tissue accumulation.
Keywords: Antimony, Strontium, Esophageal Neoplasms.

Abstract
ABSTRACT
Background and Objectives: sperm motility mainly depends on aerobic glycolysis, and lactate dehydrogenase (LDH) is a key enzyme in the last step of this process. On the other hand, fructose is considered as the main energy source for sperm motility. Therefore, this study aimed to evaluate the LDH activity and fructose levels and their correlation with sperm motion parameters in normospermic and asthenozospermic males.
Methods: In this case-control study, 96 normospermic and 96 asthenozospermic males were enrolled. The semen samples were analyzed by computer assisted semen analysis to identify sperm motion parameters. Seminal plasma fructose levels were measured using Seliwanoff's test. LDH activity in the samples was evaluated using commercially available kits. The obtained data were analyzed by SPSS software (version 16).
Results: The levels of LDH activity and fructose concentration were not different between the two groups. There was no correlation found between LDH activity and fructose concentration or sperm motility parameters. However, LDH was significantly correlated with sperm concentration in both groups.
Conclusion: Although LDH activity and fructose levels seem to be influenced by sperm motility, other factors such as sperm concentration and total sperm count can also affect their seminal plasma levels. Thus, when the sperm concentrations are equal in study groups, the level of these factors are expected to be equal.

Abstract
Background and Objective: The cell division cycle 25 (CDC25)is a familyof highly conserved dual-specificity phosphatases that activate cyclin-dependent kinase complexes. These complexes are the main cell cycle regulators. Mammalian cells ,exposure to DNA damaging radiations such as ionizing radiation and ultraviolet light, prevent cell cycle progression by activation of checkpoint pathways and lead to cell death.
Methods: In this study, mice were exposed to different doses of ionizing radiation. Their total cellular protein was extracted from the bone marrow. After determining and matching the protein concentrations, CDC25A phosphatase levels were measured by western blotting.
Results: The results showed that exposure to different doses of ionizing radiation in vivo significantly increased the expression of CDC25A compared to control group (P <0.05).
Conclusion: Exposure to ionizing radiation increases the expression of CDC25A phosphatase, which increases the possibility of tumorigenesis in that area by increasing bone marrow cell proliferation.
Keywords: Cell Cycle, CDC25A, Ionizing Radiation, Cyclin-Dependent Kinase.

ABSTRACT
Background and Objectives: Breast cancer is one of the most common cancers among women. Cardiovascular disease is one of the most important complications of breast cancer. The aim of this study was to investigate the effects of six weeks of swimming on malondialdehyde (MDA) and superoxide dismutase (SOD) levels in the heart tissue of mice with breast cancer.
Method: Breast cancer was induced in 30 female Balb/c mice (6-8 weeks old, weighing 150-200 g) by tumor transplantation. The tumor site was examined every day for the formation or absence of tumor. After becoming familiar with the laboratory environment and swimming pool, the subjects were randomly divided into three equal groups: 1. healthy control, 2. cancer control, and 3. swimming-cancer. The swimming group performed swimming training 60 minutes/day, five days a week, for six weeks. After the intervention, the levels of SOD and MDA in the heart tissue samples were evaluated by enzyme-linked immunosorbent assay. Data were analyzed in SPSS (version 16) using independent t-test at significance of 0.05
.
Results: The results showed that induction of breast cancer was accompanied by a significant increase in MDA and a significant decrease in SOD in the heart tissue of mice. Participation in the six-week swimming significantly reversed these effects
.
Conclusion: Swimming could have beneficial effects in improving oxidative factors in breast cancer patients.
