Abstract
Background: Hepatitis is a disease causing inflammation of the liver and impairment of its function .It is often transmitted through contaminated blood and blood products and may become chronic presenting with flu like symptoms .Also fatigue , loss of appetite , myalgia and arthralgia , nausea and vomiting are its remarkable symptoms. The aim of this research was to study the prevalence rate of hepatitis B in rural papulation of Garab, Padervand, Chaghabal and Tang-e Panj in terms of age, sex, job… and its comparison with prevalence rate in similar regions of our province and country. Materials and Methods: Aimed to determine the seroprevalence of HbsAg infection in areas of Garab, Padervand , Chaghabal and Tang-e Panj and relationship between defined epidemiological factors and the infection in the population under study, after providing a questionnaire containing the symptoms of the disease, the data were collected and blood specimens were obtained. Then the specimens were tested by ELISA . Results : Out of a total of 454 cases 227 were male and 227 were female ( identical sex ratio ) of them 27 cases (6.2 % ) were HBsAg positive . Out of infected persons 14 were male(51.9%) and 13 were female(48.1%) . Most infected ones were 20 to 40 years old and housewives , truck drivers and students were amongst the most infected cases . Conclusion : Based on the findings of the study heptitis B infection in these areas is far more frequent than the mean national rates amounting to 2 to 3 percent that is in accordance with surveillance system data in the mentioned areas . Although the findings does not define the main transmission pattern of the disease , when age and gender distribution of infected cases is considered ( almost equal sex ratio and preponderance of married ones ) we can state that this pattern is largely directed to sexual transmission .Although all age and sex groups are at risk , men and those at the age of 20 to 40 are more prone to infection . Occupation, blood transfusion , household dimension , vaccination history were significantly related to HbsAg infection .

Abstract
Background : Molecular diagnostic methods are among major tools in management of hepatitis C virus (HCV) in infected patients. Many studies have shown that viral load is associated with stage of infection and response to treatment. Therefore, the evaluation and quantification of viral load is very important. The goal of this study is implementation of inexpensive, yet accurate method for quantitative assessment of viral load in plasma samples of infected patients.
Materials and Methods: After development and validation of the assay, quantification of HCV RNA on 200 chronic patients the start of therapy was performed using an In-House Real-time PCR assay. Measuring the concentration of viral RNA was performed using an external standard curve. It should be noted that the validation and standardization of all procedures in this study were performed using RNA standard panel. The results of this method were compared with results obtained from Artus commercial kit.
Results: Detection limit of the assay was 50 IU/ml. The mean viral load measured on a logarithmic scale (5/81± 0/22, p<0/05). Parallel analysis of samples with commercial kit showed that there is a good correlation between these two methods (R2 = 0.988 p< 0.05).
Conclusion: Viral load detection of HCV was reported for the first time in Khorramabad city. According to the results, this method has a good sensitivity and specificity for HCV quantification in large-scale. It can be a good replacement for commercial kits especially for clinical evaluation of therapy.

Abstract
Background: Neuropathic pain is one of the most important chronic and pathological problems that can cause disruptions in human life. Some studies indicated that the release of inflammatory cytokines and increased oxidative activity can increase nerve damage. Adalimumab is a human anti-monoclonal drug that can cause therapeutic effects in different diseases. The present study aimed to investigate the analgesic effects of adalimumab in the chronic constriction injury (CCI) experimental pain model in rats.
Materials and Methods: A total of 20 male Wistar rats were utilized in this study and were randomly assigned to four groups: the first group served as the control, the second group underwent CCI, the third group received CCI in conjunction with adalimumab (5 mg/kg), and the fourth group received CCI with adalimumab (10 mg/kg). Behavioral assessments were conducted 4, 7, and 14 days post-CCI induction. The spinal cords were extracted after these assessments, and the supernatants were analyzed for inflammatory and oxidative enzymes. Data analysis was performed using Prism GraphPad statistical software.
Results: The analysis of the obtained data indicated that the injection of adalimumab in the third and fourth groups decreased the activity of inflammatory cytokines, such as TNF-α, IL-6, and CRP. In addition, it decreased the activity of MDA and increased the SOD and CAT enzymes. Moreover, adalimumab significantly improved the outcomes of thermal allodynia, mechanical allodynia, and thermal hyperalgesia in the CCI rats treated with this medication.
Conclusion: The administration of adalimumab can be used to treat or reduce neuropathic pain with its anti-inflammatory and antioxidant activity, along with neuroprotective effects.
