Background & Objective: Hepatitis B virus (HBV) infection is one of the most important health problems all over the world. This study was conducted to determine the co-infection of hepatitis C virus (HCV), hepatitis D virus (HDV) in HBV infected patients in Golestan province of Iran. Materials & Methods: This population based cross sectional study was done in 2004. 139 HBsAg positive cases were assessed for co-infection with HCV and HDV. Serologic tests were done by ELISA method using available kits. Data were analyzed by SPSS-12 and STATA8 software. P-values of less than 0.05 were considered as significant. Results: Sixty eight (48.9%) of 139 cases were males and 71 (51.1%) were females. The mean (±SD) of participant's age was 41.89 (±11.3) years (range: 25-64 years). Anti-HCV and Anti-HDV antibodies were positive in 17 (12.3%) and 8 (5.8%) cases, respectively. Females were more infected with HCV and HDV than males. But the differences were not significant. Conclusion: The prevalence of co-infection with HCV and HDV in HBV infected cases is relatively high and notable in Golestan province of Iran. Because of negative effects of these co-infections in clinical outcome of the disease, it is recommended to assess possible HCV and HDV infection in individuals with HBV infection. This may result in more efficient management of the disease.

Background and Objective: Esophageal and gastric cancers are among the most common and fatal cancers. These are diagnosed at the latest phase and the prognosis is too poor. Due to the importance and high incidence rate of the upper gastrointestinal cancers in Golestan province, this study was conducted to explore the overall survival rate of these patients in rural area of this region. Materials and Methods: In this descriptive cross-sectional study, a total of 121 pathologically confirmed esophageal or gastric cancers, with rural place of residence, were retrieved from the cancer registry at the health department in Gorgan. After conducting interview with patients or their relatives, analysis of their sociodemographic and clinicopathologic features was performed. The median survival rate was compared regarding age groups and gender using Kaplan-Meier statistical test. Results: Male to female ratio in esophageal and gastric group were 1.2 to 1 and 3.8 to 1, respectively. Short-term survival rates were 54.76% and 26.2% for esophageal cancer and 66.6% and 37.5% for gastric cancer. Collected information regarding patients’ sociodemographic and clinicophathologic factors did not have significant association with patients’ survival in both esophageal and gastric cancers. The mean survival rate in patient with gastric and esophageal cancers according to age and gender was not significant. Conclusion: This study showed that the overall short-term survival rates for upper gastrointestinal cancers are very low in Golestan province. Therefore the need for intervention the need and allocating more diagnosis and therapeutic resources for upper gastrointestinal cancers are required.

Background and Objective: Acquired immunodeficiency syndrome (AIDS) is a definition of dysfunction of immune system in human that is induced by infection with a virus named human immunodeficiency virus (HIV). The most high risk group in HIV infected people are intravenous drug users (IDUs) with unsafe sex. This study was conducted to evaluate knowledge and attitude of IDUs with unsafe sex about AIDS and relation with socioeconomic levels in Golestan province in North of Iran. Materials and Methods: This Cross-Sectional study was conducted on 134 IDUs in Golestan province during 2007. Samples were chosen by a random systematic method. Data was collected with interview by standard questionnaire. Data was analyzed by SPSS-16 and One-way ANOVA,T-test student, Kruskal-wallis, Mann-Whitney U and Kendall tests. Results: This study showed that 36.6% of samples had moderate knowledge about AIDS and 49.3% of them had negative attitude about AIDS. 67% of subjects had education between 6-12 years, 44.8% were married and 53% were jobless and without income. Level of knowledge had a significant relation with age (P<0.05) and education level (P<0.05). Older subjects had better knowledge. Level of knowledge in 25-34 years group was higher than other age. Well educated people had higher knowledge compared with low educated and illitrate subjects. Level of knowledge had a significant relation with attitude (P<0.05). Conclusion: The findings of this study showed that 65% of subjects with high risk behavior on HIV/AIDS had a appropriate knowledge about transmission of HIV, but half of these population have a poor HIV/AIDS attitude.

Background and Objective: Hypertension is considered as a major public health problem in most countries due to its association with ischemic heart disease. The aim of this study was to determine people awareness of hypertension in Golestan province of Northern Iran.

Materials and Methods: This cross sectional population based study carried out on 2497 subjects (15-65 years old) including 1500 men and 1247 women in Golestan province- Northern Iran during 2006. The subjects were chosen by proportional-cluster sampling based on sex and age groups. The subjects were interviewed, antropometric indexes and serum biochemical factors were evaluated. Blood pressure was measured three times with 5 minutes interval and defined based on JNC-7 classification. Serum cholesterol and fast blood sugar (FBS) were determined using laboratory kits (enzymatic methods), and spectrophotometery technique. Data was analyzed by SPSS-16 software and Chi-Square test.

Results: In general, the prevalence of hypertension in this region was 23.9%. with higher rate among women urban area by 3.3% and 5% respectively. Only 48.7% of hypertensive patients were aware of their disease and that was significantly more in women than men (P<0.001). Low physical activity, chronical age, diabetes, hypercholesterolemia, general obesity, central obesity and illiteracy were the risk factor for hypertension morbidity (P<0.05).

Conclusion: This study showed, in spite of prevalency of hypertension among 20% of subjects in this area only 48.7% of them were aware about their disorder.

Background and Objective: Alpha thalassemia is one of the most common hemoglobin disorders. Some combination of alpha globin gene mutations may cause HbH disease with severe anemia or intermediate thalassemia. genotype common deletions are routinely tested for suspicious alpha thalassemia couples but because of lack of information about the nature and frequency of point mutations and higher expenosor of sequencing, less attention was paid to them. This study was done to determine the prevalence of common point mutations of alpha globin gene in Babol, Iran.

Materials and Methods: This descriptive study was carried out on DNA of 153 adult suspected to α-thalasemia with deleted α- golobolin gene referred to genetic laboratory in Babol, Iran during 2005-09. a1 and a2 genes were amplified by using specific biotinilated primers by PCR method. PCR products were assayed using 11 specific probs corresponding to common point mutations in alpha gene (C19, IVSI (-5nt), C59, Hb constant spring, Hb Icaria, Hb seal Rock, IVSI (148), C14, poly A (-2bp), poly A2, Poly A1) and fixed on byodine C membrabe. Hybridization between the probes and PCR products was visualized after a colorimetric reaction using of conjugated streptavidin peroxidase and TMB (tetra methyle Benzidine) and H2O2.

Results: The prevalence of point mutations in poly A2, 5nt, Hb constant spring and poly A1 were 28.75%, 14.38%, 7.84% and 2.61%, respectively.

Conclusion: Point mutation in alpha globin genes was detected in %53.60 out of 153 adults suspected with alpha thalassemia without common deletion mutations.

Background and Objective: Considering the importance of coverage and quality of data in Golestan population-based Cancer Registry (GPCR), northern Iran. This study was conducted to determine the effect of the referral of cancer patients to medical centers outside Golestan province on the coverage of the population-based cancer registry program.
Methods: This descriptive-analytic study was performed on all cancer patients registered in the diagnostic centers of Golestan province, northern Iran during 2008-10. Data of patients referred to the centers of the province from the bank of the Golestan province cancer registry program and data of patients referred to the centers outside the province were received from the Ministry of Health Department of Cancer. Data were analyzed using the record linkage method.
Results: A total of 6083 new cases of cancer were registered in Golestan province. According to the cancer data, 678 (11%) of them were referred to outside of Golestan province centers. 343 of these 678 patients (50.6%) were found as duplicate records between the two datasets. The most frequent cases were gastric cancers (70.4%), breast (63.5%) and esophagus (62.5%).
Conclusion: This study suggested that referrals of cancer patients to centers outside the Golestan province may result in an underestimation of about 5% in GPCR. This level of underestimation seems to have no considerable effects on completeness and quality of data in the GPCR.

Background and Objective: Creatine is one of the most important and commonly used supplements athletes, although the molecular mechanisms of creatine and its side effects are less understood. The high level of the ceratin kinase enzyme and lactate dehydrogenase enzymes are considered to be a sign of cell damage. This study was done to determine the effect of creatine monohydrate supplementation on creatine kinase (CK) and lactate dehydrogenase (LDH) enzymes following a severe muscle contraction in female athletes.
Methods: In this double-blind clinical trial study, 30 female athletes were randomly divided into intervention (creatine supplementation 0.3 grams per body weight for 4 times duing 7 days and control (placebo, starch powder) groups. Blood sample was collected before supplementation (pre-test) and 24 hours after Cunningham exercise test (post-test) to measuring CK and LDH in each subject.
Results: After intervention, the level of CK (323±63 IU/L) and LDH (119±13 IU/L) in intervention group had no significant difference in compared to control group (CK: 328±44 IU/L and LDH: 122±14 IU/L).
Conclusion: The usage of a 7-day course of creatine supplement did not significantly change the CK and LDH levels following a severe muscle contraction in female athletes.

Background and Objective: Temporal lobe epilepsy is characterized by the degeneration of hippocampal neurons and the sprouting of mossy fibers in the dentate area. This study aimed to investigate the impact of the hydroalcoholic extract of Rosa damascene on hippocampal tissue changes induced by kainic acid-induced epilepsy in rats.
Methods: In this experimental study, 28 male Wistar rats weighing between 185-225 grams were used. The animals were divided into four groups: sham group, sham treated with hydroalcoholic extract, epilepsy (kainic acid), and epilepsy pretreated with hydroalcoholic extract. Kainic acid was used for intra-hippocampal and unilateral injection to induce epilepsy in the animals at 0.8 micrograms per rat. The rats were given 500 mg/kg of the extract intraperitoneally daily for one week before surgery. Five weeks after surgery, thionin and Tim staining methods were performed on the hippocampal slices.
Results: Kainic acid-induced epilepsy resulted in convulsive behavior, and pretreatment with the hydroalcoholic extract significantly reduced the intensity of convulsive attacks (P<0.05). The density of neurons in the CA3 area of the hippocampus in the kainic acid group showed a significant decrease compared to the sham group (P<0.05), while pretreatment with the extract caused a significant increase in the number of neurons in this area compared to the kainic acid group. Additionally, a significant increase in the intensity of mossy fiber sprouting was observed in epileptic rats compared to the sham group, and pretreatment with the extract significantly decreased its intensity (P<0.05).
Conclusion: The pre-treatment with the hydroalcoholic extract of Rosa damascena decreased convulsive behavior, protected hippocampal CA3 neurons and reduced the intensity of sprouting in the hippocampal dentate region in the experimental model of temporal lobe epilepsy induced by kainic acid.
