Abstract
The Islamic Republic of Iran, in her 20 year vision by the year 2025, is a developed country with the first economic, scientific and technological status in the region, with revolutionary and Islamic identity, inspiring Islamic world, as well as effective and constructive interaction in international relations. Enjoying health, welfare, food security, social security, equal opportunities, fair income distribution, strong family structure; to be away from poverty, corruption, and discrimination; and benefiting desirable living environment are also considered out of characteristics of Iranian society in that year. Strategic leadership towards perceived vision in each setting requires restrictive, complete and timely information. According to constitution of National Institute for Health Researches, law of the Fifth Development Plan of the country and characteristics of health policy making, necessity of designing a Health Observatory System (HOS) was felt. Some Principles for designing such system were formulated by taking following steps: reviewing experience in other countries, having local history of the HOS in mind, superior documents, analysis of current production and management of health information, taking the possibilities to run a HOS into account. Based on these principles, the protocol of HOS was outlined in 3 different stages of opinion poll of informed experts responsible for production on management of information, by using questionnaires and Focus Group Discussions. The protocol includes executive regulations, the list of health indicators, vocabulary and a calendar for periodic studies of the community health situation.

Abstract
A new kinetic method has been developed for the determination of iodine in water samples. The method is based on the catalytic effect of I(-) with the oxidation of Indigo Carmine (IC) by KBrO(3) in the sulfuric acid medium. The optimum conditions obtained are 0.16 M sulfuric acid, 1 × 10(-3) M of IC, 1 × 10(-2) M KBrO(3), reaction temperature of 35°C, and reaction time of 80 s at 612 nm. Under the optimized conditions, the method allowed the quantification of I(-) in a range of 12-375 ng/mL with a detection limit of 0.46 ng/mL. The method was applied to the determination of iodine in river and city water samples with the satisfactorily results.

Abstract
BACKGROUND Life expectancy at birth as an alternative summary measure of mortality represents number of years which a newborn will be alive based on the current age specific death rates. As it summarizes death rates across all age range in a given population is the most common summary measure of mortality. The aim of this study was to correct death rates for underreport and estimate life expectancy at birth in rural population of Iran in 2008. In addition, this study aimed to assess the Vital Horoscope system's data quality. METHODS Data were obtained from all Health Houses in Iranian villages in 2008. In order to adjust over 5 years old death rates for underreport, we used Brass Growth Balance method. Since this method is not applicable to under 5 years old, we used child mortality rates projected based on the Iranian Demographic and Health survey 2000 to correct death rates. RESULTS Adjusted life expectancy at birth for males was 71.5 year and for females was 74.4 year. Completeness of the death data was 88% for males and 79% for females. Adjusted child (under 5) mortality rate by sex in males and females was 25.9 and 23.8 per 1000 live births respectively. Adult mortality for males was 167.2 and 98.3 for females per 1000. CONCLUSION Data based on Vital Horoscope system are a suitable source to estimate life expectancy and other mortality statistics. Also has an acceptable completeness on death registration. Further studies to investigate accuracy of data from the Vital Horoscope system are suggested.

Abstract
BACKGROUND It is estimated that about 370 million people are chronic carriers of HBV worldwide. Apparently 3% of Iranian populations are chronic carriers of this virus. We aimed to evaluate the viral DNA in biological fluids of chronic hepatitis patients compared to a control group. METHODS The current case-control study was designed to evaluate the viral DNA in biological fluids of 70 chronic hepatitis patients compared to a control group using ELISA, PCR and Real Time. RESULTS All individuals (100%) in case group were HBsAg positive while in control group only 2 individuals (2.8%) were HBsAg positive. Three individuals, in control group were positive using PCR and Real Time PCR indicating that about 7% of those in control group were chronic carriers of HBV. The interesting point was the copy of viral DNA; (5.49 ×10(4), 2.162×10(3) and 7.26×10(6)) for 3 chronic carriers using sera while it was about (5.71×10(3), 1.45×10(2) and 2.56×10(5)) using ear cerumen confirming the necessity of investigating for the carriers of HBV in different biological fluid and by different methods. CONCLUSION It can be concluded chronic carriers of hepatitis B are much more than what is diagnosed by routine diagnostic tests. On the other hand ELISA alone can not be relied on as a complete test for screening of chronic carriers in hepatitis B. PCR and Real Time PCR are more reliable tests for this purpose.

Abstract
Merozoite surface protein 2 (MSP-2), a very immunogenic malaria antigen, is a highly polymorphic 45-53 kDa merozoite surface protein, which is regarded as a promising vaccine candidate. The highly polymorphic nature of MSP-2 suggests that the molecule can be involved in protective immunity against malaria. The antibody responses to MSP-2 antigen are mostly directed against polymorphic and dimorphic regions of the protein. The current study aimed at testing the reactivity of human sera from a malaria-endemic area of Gambia against MSP-2 regions 2, 3 and 4 compared to crude schizont extract in a period of 20 years. The age-dependent immunity was analysed in a manner of cross-sectional study (the data of the first visit) and also a longitudinal study design (analysing the data at four different time points from 1960 to 1980) testing the sera of 178 individuals randomly selected from the Keneba Serum Collection by using MSP-2 recombinant protein. The total IgG responses were measured by ELISA. Kolmogorov-Smirnov was used to check the normal distribution of OD, Hb and parasitaemia, and then Spearman correlation was applied to analyse the data. Most sera recognized, predominantly, the variable regions of the MSP-2, particularly the domain 3. The IgG response against all the antigens increased with age. The IgG responses against domain 3 of MSP-2 were associated with an increase in haemoglobin levels but a decrease in parasitaemia, suggesting that this immune response may be one of the most useful means for further studies on protective immunity against malaria.

Abstract
We used data from the baseline survey from the Isfahan Healthy Heart Programme to determine the prevalence of hypertension, dyslipidaemia and diabetes among a representative samples of 12,514 adults living in 3 cities in the Islamic Republic of Iran. The prevalence of hypertension, dyslipidaemia and diabetes was 17.3%, 66.3% and 5.6% respectively. Awareness, treatment and control of hypertension were 40.3%, 35.3%, and 9.1% respectively. The rates for dyslipidaemia were 14.4%, 7.1% and 6.5% respectively, and 54.6% of diabetics were aware of their disease and 46.2% were under treatment.

Abstract
The aim of this study was to determine the seroprevalence of hepatitis C infection and associated risk factors among addicted prisoners in Sari-Iran. This is a simple random sampling cross sectional study that was performed on 312 addicted prisoner men at Khazarabad addicts' prison in Sari/Iran in September 2001. Their blood samples were examined through third generation enzyme immunoassay. Data were collected through questionnaires and interview. Associated risk factors were compared in 82 hepatitis C antibody positive addicts (the affected group) and 148 hepatitis C antibody negative addicts (the unaffected group). Out of 312 addicted prisoners, 96 were hepatitis C anti body positive. The seroprevalence of hepatitis C infection was found to be 30.8%. Major associated risk factors in the affected group were as follows: duration of addiction, duration of imprisonment (mean 48 months), route of drug administration, length of alcohol consumption, tattooing, shared usage of needles and razors, multiple sexual partners and type of drugs (p < 0.05). On multivariate logistic regression analysis these factors were found to be significant independent risk factors for HCV infection: tattooing (OR 100, 95% CI), multiple sexual partners (OR 4.97, 95% CI) and history of surgery (OR 6.23, 95% CI). It is concluded that hepatitis C infection had a considerable prevalence in addicted prisoners. High risk and unsafe behaviors were found to be the main factors of contamination.
