  Several reports revealed that plasma level of essential trace elements like magnesium, calcium and phosphorus altered in diabetics. These micronutrients especially magnesium are suspected to have effective roles in pathogenesis and progression of diabetes. The studied subjects consisted of 96 diabetic volunteers (66.8%) females (mean age rate of 51.8±9.37) and (31.3%) males (mean age rate of 49.8±14.84) admitted in diabetes clinics of Gorgan city (Northeast of Iran). In these patients, the plasma level of Mg measured by simple sampling method due to a cross-sectional designated project. Glycated hemoglobin (HbA1c) also measured as a glycaemia control index. Hypomagnesia states were positive in 48 cases (50%). Housekeepers together with low educated individuals had significantly lower Mg plasma level as compared to other studied groups (p<0.05). No significant relationships were seen considering other variables. In respect to significant alterations of Mg plasma level that also reported in other such studies, it is recommendable to provide complementary supplication of such micronutrients for diabetics.

  The purpose of this study was to evaluate the effect of pesticides on blood indices of subjects which are exposed to organophosphate toxins. This research was a cohort study which was carried out during 2005 on the employee of a pesticide factory in Golestan province (North of Iran). In this study the sampling from 63 subjects was carried out for two sessions in days 1 and 90. CBC and hematologic indices performed by cell counter instrument. The mean of MCV in phase 1 was 82.8±7.1 fl and in second phase the MCV was 80.3±6.7 fl. This drop in MCV statistically was meaningful (paired t-test, mean = 2.5, 95% CI=2.0-2.9, p<0.001). Erythrocyte number, hemoglobin, HCT and MCHC increase in second phase compared to first phase statistically was meaningful. There was not any significant relation between the place of work and variation of red blood cell indices. In regard to the changes in hematologic indices in workers of pesticide factory in a three months period, it seems logical to set up a program to have a routine check on the hematologic indices in working personal engaging in such occupations.

  The aim of this study was to determine the seroprevalence of HCV in HBsAg positive subjects. In a population based single stage cluster sampling in Golestan province of Iran, 139 HBsAg positive subjects were detected and enrolled in the study. Serum samples were tested using ELISA method for anti-HCV antibodies. Chi-square and Fisher`s exact tests were used to compare the proportions. There were 68(48.9%) male and 71(51.1%) female. The mean age was 41.89±11.30 years (25-64 years). One case was excluded because of inadequate blood sampling. Anti-HCV antibody was positive in 17(12.3%) of 138 remaining subjects. Seropositivity of HCV in female was higher than male (14.1% versus 10.4%, respectively) but the difference was not statistically significant (p = 0.52). No significant relationship was seen between Anti-HCV seroprevalence and demographic factors such as age, place of residence and marital status. The seroprevalence of co-infection with HBV and HCV in our study was higher than such reports from some countries (Italy); but it was in line with worldwide prevalence (>10%). A careful longitudinal evaluation of the viremia levels of both HBV/HCV viruses is essential for making a correct diagnosis and tailoring the appropriate therapeutic schedule in co-infected patients.
