Abstract Background & Objectives: Thalassemia syndromes isone of the inherited disorders in which one or more globulin chains are affected. On the basis of clinical symptoms, thalassemias are categorized as minor, intermediate, and major. Minor beta -thalassemia is a mild microcytic hypo chromic anemia in most cases asymptomatic and HbA2 is more than normal. Materials & Methods: This study carried out on 813 blood samples obtained from male high school students of Aliabad Katool, in the north of Iran. After detecting red blood cell indices of the subjects whose MCV was less than 80fl HbA study performed. Results: The MCV of 8.24% of the subjects was less than 80fl.34 of 67 had HbA2 of less than 3.5 %(normal) while the rest more than 3.5%(minor). Conclusions: Since about 50% of microcytic anemic patients were the carrier of beta-thalassemia and it is highly Prevalent in this region (4.06%), we recommend to investigate HbA2 in people with MCV less than 80 fl.

Abstract Background and objectives: Human T-Lymphocyte Virus-1 (HTLV- 1) is known as the etiologic factor of acute T-Lymphocytic Leukemia (ATL) and tropical spastic paralysis. (TSP). Endemic factors causing infection with Human T Lymphocyte Virus-1 (HTLV-1) is based on environmental, socio-economical and health behaviors of the individuals. This virus is well distributed in families with involved members. Golestan province is located in North West part of Northern Khorasan province that had already been known as an endemic area for HTLV-1. This virus is also known as the main etiologic factor for cancers and ATL, therefore we studied the prevalence of HTLV-1 seroepidemiology in Golestan province. Material and Methods: The subjects selected by cluster sampling were 2034 healthy cases residing in different parts of Golestan province. ELISA method using Dia- pro anti HTLV-1 antibody kits was applied for serological assessment. Western Blot (HTLV BLOT 2.4) was used for confirmation purposes. Results: The subjects aged 38.66±16.54 were 2034 healthy persons. Forty-one point seven of these cases were males and the rest females. Based on ELISA method there were15 HTLV-1 positive cases (0.7%). -1. (0.7%) Six out of 15 were confirmed by western blot method (95%, CI: 0.06-0.53%). The highest prevalence sigllificant) aiology is in the highat rate in 31-40 year old gro0.7%). onclusion: This study shows that HTLV-1 is prevalent in Golestan the same as the other parts of the world. There fere: we urse on performing screening test (HTLV-) on donated blood components before delivering (OK labeling). Key words: HTLV-1, Seroepidemiology, ELISA, Western Blot, Golestan ATL(Acute T lymphocytic Leukemia) Six cases out of 15 were confirmed by western blot method (95%, CI: 0.06-0.53%). The highest prevalence was 2.6% seen in Kalaleh city (east part of the province) [95%, Cl: 0.06-0.53%). There was significant difference between the prevalence of HTLV-1 and the dwelling place. (p=002). HTLV-1 seroepidemiology was in the highest rate in 31-40 year old group (0.7%). Conclusion: This study shows that HTLV-1 is prevalent in Golestan province, the same as the other parts of the world. Therefore, we recommend performing screening test (HTLV-) on donated blood components before delivering (OK labeling).

Abstract Background and Objectives: Erythrocyte indices are helpful for monitoring the erythrocyte synthesis and liver condition. The pesticide factories’ staff are being exposed to poisoning. This article aims to evaluate the effect of pesticides on blood indices of subjects which are exposed to organophosphate toxins. Material and Methods: This cohort study was conducted on the 63 employees of a pesticide factory In Gorgan.Iran (2005). We performed a two-step Sampling, The beginning of working season and three months later. Then, data analysis was carried out (p<0.05). Results: The difference between the mean of MCV in phase one (82.8 ± 7.1 fl) and phase two (80.3 ± 6.7) is Significant (p<0.001). The increase of Erythrocyte, hemoglobin, HCT, and MCHC in the second phase was statistically meaningful. There is not any significant relation between the work place, Record of Services and red blood cell indices. Conclusion: In regard to the changes in hematologic indices in a threemonth period, it seems logical to set up a program to have a routine check on the hematologic indices in people engaging in such occupations Key words: Pesticide, organophosphate toxins, hematologic indices, MCV, hemoglobin, hematocrit.

        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.
