Abstract
Abstract Background and objectives: HTLV-1 virus belongs to the retrovirus and infection with this virus mostly is seen among people having more than one time blood transfusion. Because of requiring repeated blood transfusions, thalassemic patients are considered to be high risk subjects in this regard. Thus, this study was carried out to indicate the frequency of HTLV-1 infection among the thalassemic patients. Materials and Methods: Blood samples of 181 thalassemic patients referred to Taleghani hospital during nearly two years (2004-2005) were taken. By using ELISA technique, the sera were assessed to determine HTLV antibody. The positive ones subsequently were examined by western Blot (kit, 2.4) to confirm the ELISA positive samples and also to recognize the HTLV type. Results: Of 181 thalassemic patients, 93 (51.4%) were male. The age was between one and twenty five (14.11 ± 6.5). 93.4% (169) were received packed cell only once in a month. 14.9% (27) were HTLV positive by ELISA technique, while just eight out of these 27 were considered to be true positive by Western blot and to be contaminated by type one virus. Of all subjects, 4.4% were positive HTLV1. Furthermore, the contamination with this virus is increased as the patients getting older. Conclusion: The findings indicated that among the thalassemic patients in Gorgan, there are cases with HTLV-1 whose frequency is correlated with the other part of our country. Consequently, further comprehensive studies are required to identify those infected blood donated to minimize the transmission risk of this infection in the society and in particular among the people receiving blood, such as thalassemic patients.

Abstract Background and objectives: Hemin is a porphyrin compound derived from hemoglobin, the precursor of other porphyrin hemoglobin derivatives and the raw material of Hematin. Since hemin is widely used in medicine, we decided primarily to synthesize this substance in Laboratory and to determine the best way of hemin extraction from untransfused and expired blood units. Materials and Methods: In the first method, Glacial acetic acid and sodium chloride were added to citrated blood and hemin crystals were extracted by means of cooling. Finally, the obtained product, by visible spectrophotometer and Infrared Spectrophotometer, was compared to standard samples. Fur thermore, citrated blood, citrated blood hemolysed by distilled water and citrated blood washed by normal saline were used comparatively as a raw material to produce Hemin. The second method was performed by adding Strontium, acetic acid and acetone to blood samples and then after precipitating Hemin crystals they were washed and dried with acetone. Results: The presence of functional groups in Hemin samples, analyzed by infrared Spectrophotometer, indicates the production of this compound. The results of visible Spectrophotometer in comparison with control samples and the results of samples weighting demonstrates high efficiency of extraction stages and the purity of obtained compound. Conclusion: The use of intact citrated blood produces more Hemin than the other kind of Citrated blood samples. Moreover, acetic acid with citrated blood, without any processing on blood, is the best way for Hemin production. Key words: strontium, Hemin, Blood, acetic acid, extraction

Abstract Background and objectives: Resistance to antimicrobial agent is a world-wide problem and the existed reports are not the same. Aware of antibiotic resistant pattern of microorganisms in each hospital is important for controlling the nosocomial infections. This study was designed to determine the resistant pattern of microorganisms isolated in Yahya nejad hospital, Babol, north of Iran. Material and Methods: In this descriptive study, organisms were isolated during 2006 from urine, blood, endotracheal tube, abscess, fluids (ascites, pleura, and synovia), wound, discharges and bonemarrow of both outpatients and inpatients in our hospital were studied. Their antibiotics resistances were evaluated by Kirby Bauer method. Results: of 3114 culture specimens of admitted patients (female 1732, male 1382), 325 (10.4%) microorganisms were isolated. They were isolated from urine 162(49.8%), blood 115(35.4%), abscess 11(3.4%), wound, 10(3.1%) and discharge10 (3.1%). The most common microorganisms were Escherichia coli 107(33%) and Staphylococcus epidermidis 69(21.3%). Maximum resistance of E.coli is related to tetracycline (83.9%) and ampicillin (75%) and maximum resistance of S.epidermidis to oxacillin (89.2%) and penicillin (82.1%). Conclusion: With regard to high antibiotic resistance (>70%) in this study, it seems that the early beginning and inappropriate dosage of antimicrobial agents may be associated with developing antibiotic resistance. Hence, it is highly recommended to prohibit the unnecessary prescription of antibiotics Key words: Antibiotic resistance, microorganisms, Blood culture, E.coli

Abstract
Background and Objective: Carbohydrates are considered as the major source of energy in physical activity. Studies show that consumption of carbohydrate foods before exercise can balance blood glucose and free fatty acids and increase athletes’ performance. In this study , we compared the effect of three kinds of foods with different glycemic indices on blood glucose (BG) and serum free fatty acids (FFA) in cycling ,male athletes.
Material and Methods: In this clinical trial, 21 members of national cycling team randomly allocated to three equal groups of glucose (low glycemic index) ، lentil (low glycemic index) and potato (high glycemic index). First, Fasting blood samples (5ml) were obtained to measure BG and FFA . Then the subjects were asked to eat their foods. After 45 mins of rest, they pedaled with maximal oxygen consumption VO2max) for two hours and again their blood samples were taken to compare with the levels of before interventions.
Results: Glucose consumption resulted in a significant decrease in FFA level after 2 hours of pedaling (P = 0.01) but no significant change in BG level. Plasma glucose was higher after eating lentil than that of potato (P<0.05), but it was not true for FFA level of both groups.
Conclusion: based on the results, the pre-exercise use of low glycemic index (lentil) compared to high glycemic index (potato) can better lead to increased blood glucose during exercise.

Abstract
Abstract Background and Objective: One of the main causes of increased mortality in cancer patients is bacteremia. On the other hand, antibiotic resistance is the major cause of treatment failure in malignant diseases especially in hematological malignancies. The aim of this study was to diagnose the bacterial strains isolated from blood specimens of cancer patients and to determine their antibiotic susceptibility. Material and Methods: In this cross-sectional study, 0.5 ml of venous blood was taken from 613 cancer patients especially leukemia, and blood cultures and antibiotic susceptibility tests were performed using standard methods. Using disc diffusion method, antibiotic susceptibility was performed with a wide range of antibiotics. Results: Out of 613 cultured specimens, 153 (25%) were found to be positive including 76.47% of gram negative and 23.53% of gram positive bacteria. The most common isolated bacteria were E. coli, coagulase-negative Staphylococci, Klebsiella, Staphylococcus aureus and Pseudomonas aeroginosa, respectively. Conclusion: It seems that Ceftriaxone is the best choice for the treatment of gram negative caused bacteremia and Gentamicin for bacteremia caused by gram positive agents. Given the high level of resistance to the commonly used antibiotics, it seems reasonable to avoid of early and inappropriate use of antibiotics to prevent the development of drug resistant bacteria.

Abstract Background and Objectives: Giardia lamblia and Entamoeba histolytica are the most prevalent human intestinal pathogenic protozoa, worldwide. The clinical features of Giardia infection are acute diarrhea, a chronic condition with continuous diarrhea and malabsorption. Entamoeba histolytica invade intestinal tract without any typical clinical indications, and it can involve liver and other organs too. Therefore, we aimed to study these protozoa by serological and parasitological methods. Material and Methods: In this comparative study, the stool and blood specimens were collected from 1025 patients selected via simple random sampling in three different laboratories located in Tehran and Karaj, Iran (2012). Formalin Detergent test was performed on all samples. Both serum and stool positive samples of this method were analyzed for antigen and antibodies related to Giardia lamblia and Entamoeba histolytica, respectively. Results: of 1025 stool specimens, 76 (4.7%) were positive for Giardia lamblia and 19 (1.8%) for Entamoeba histolytica using Formalin-detergent method. In ELISA, 81 (7.9%) coproantibodies to Giardia lamblia and 24 (2.3%) coproantibodies to Entamoeba histolytica, 78 (7.6%) corproantigen for Giardia lamblia, and 5 (0.4%) for Entamoeba histolytica were observed. circulatory antibodies to Entamoeba histlytica were detected in 22 cases (2.1%) Conclusion: Sensitivity of microscopic method compared to serological methods is higher than 90% therefore, Formalin-detergent method can be the best method for stool examination.

Abstract
Background and Objective: According to recent changes in diagnostic criteria for diabetes, the harmonization of results obtained from various methods and systems by considering their accuracy and precision is essential. This study aimed to evaluate the accuracy, precision and consensus of some routine laboratory glucose kits in comparison with Hexokinase reference method.
Material and Methods: The participants were 38 diabetic patients with fasting blood sugar (FBS) ≥126 mg/dl, nine prediabetic patients with FBS of 100-125 mg/dl, 15 non-diabetic people with FBS of 60-100 mg/dl and 9 hypoglycemic patients with FBS of ≤60 mg/dl. Their FBS were measured by four routine laboratory glucose kits: Glucose oxidase on BT3000 analyzer with an open system and Hexokinase reference method on a close system (COBAS INTEGRA®400plus analyzer, Roche kit). Accuracy and precision were determined and compared with reference method.
Results: Glucose oxidase methods showed a good agreement with the reference method, in Correlation Coefficient>0.99. based on regression analysis, the slope of 1.114 for Pars Azmoon, 1.105 for Bionik, 1.121 for Elitech and 1.087 for Human were reported (P<0.05). Error of the mean for ParsAzmoon was 12.79, for Bionik 10.86, for Elitech 12.58 and for Human were 8.46. Coefficient of Variation showed more imprecision for Bionik and Human kits.
Conclusion: given the same almost standard errors, standard devisions and regression analysis, the precision in four methods is the same but in comparison with Hexokinase, reference method has not the accuracy.

Abstract
Background and Objective: Given that microbial contamination is the third largest cause of mortality caused blood transfusion, the examination of contamination in platelet concentrates is essential in blood transfusion centers. The purpose of this study was to achieve a rapid test for bacterial contamination of platelets concentration.
Material and Methods: This laboratory study was conducted on 14 bags of platelet concentrates prepared from Yazd Blood Transfusion Center. Six platelet bags were infected by Staphylococcus epidermidis; six by Klebsiella with a concentration of 150, 15 and 1.5, and two bags were considered as control. In specific intervals, the bags were sampled aseptically and examined by the methods including culture, gram stain, Glucose and PH measurement.
Result: Due to the presence of dextrose, the initial glucose level of platelet bags was above 300 mg/dl. The mean of Glucose in contaminated platelet bags was progressively decreased in 3 days in that it reached 165 mg/dl in the third day ( p = 0.002) . The level of PH had a declining process in that it averagely decreased from PH 7.3 to PH 5.2 (P=0.017(. The results of culturing and smear of the bacteria were different according to the concentrations used in the study.
Conclusion: We can detect the contamination of platelet bags by measuring the level of glucose and PH level in the least amount of time.

Abstract
Background and Objective: Aluminum Phosphide (ALP) is a solid non-organic phosphide with dark gray or dark yellow crystals. It reacts with stomach acid after ingestion and causes phosphine gas to be released. It is thought that phosphine causes toxicity from enzymatic interference and may even lead to cell death. This study aimed to investigate the effects of poisoning with rice tablet on levels of platelets, hemoglobin, white blood cells.
Methods: The clinical records of 67 cases of acute oral toxicity with aluminum phosphide admitted to Baharloo hospital and 28 forensic autopsy cases in Kahrizak forensic research center were studied. Recorded information included vital signs, demographic characteristics, numerous laboratory and clinical findings, complications and all pathologic findings.
Results: All patients had received standard symptomatic and supportive treatments. Among the tested subjects, 30 of 67 patients (44.8%) were male. The mean hemoglobin level of recovered and deceased individuals was 12.26 and 11.72 g/dl, respectively. There was a significant relationship between patients’ WBC counts and mortality where the mean level of WBC in the deceased was more than that of the recovered (P=0.001). Mean SBP in the deceased and the recovered individuals was 79.67 ± 12.89 and 102.46 ± 22.57 mmHg, respectively.
Conclusion: Consumption of rice tablets results in blood pressure alteration, hemoglobin levels, platelets and leukocyte count. Tracking these alterations can reduce the side effects and mortality rate in the cases of rice tablet poisoning.

Abstract
ABSTRACT
Background and Objective: The association of Triglyceride/High Density Lipoprotein-Cholesterol (TG/HDL-C) ratio with fasting serum insulin, which is an alternative method of insulin resistance (IR) measurement, is well-recognized. Thus, the measurement of TG/HDL-C ratio is useful to determine both IR and dyslipidemia, which itself is a characteristic of individuals with IR. Therefore, this study aimed to investigate the relationship between TG/HDL ratio as an indicator of IR, with different fasting blood glucose levels.
Methods: This case-control study was performed on 343 volunteers with no history of diabetes or use of blood glucose-lowering medications and fasting blood sugar (FBS) levels of less than 126 mg/dl. After sampling, the subjects were divided into three groups based on their FBS level. First group included healthy subjects with FBS of less than 100 mg/dl. Second group consisted of subjects with impaired fasting glucose (IFG) and FBS of 110-100 mg/dl and a third group including those with impaired glucose tolerance (IGT) and FBS of 110-125 mg/dl.
Results: The amount of TG/HDL-C ratio was 3.8 ± 2.8, 4.0 ± 2.1 and 5.4 ± 3.8 for the healthy group, individuals with IFG and IGT, respectively. The TG/HDL index was significantly different among the tested groups with no significant difference between healthy subjects and subjects with IFG. Moreover, there was a statistically significant difference between the IGT and IFG groups with healthy individuals.
Conclusion: Considering the significant increase of the TG/HDL ratio in groups with impaired glucose, using this index can be helpful in evaluation of glycemic disorder.

Abstract
Background and objectives: The aim of this study was to investigate the effect of eight weeks of aerobic exercise on serum iron, serum ferritin, platelet count, mean platelet volume, and some immunity indices in non-athlete females.
- In this study, 30 non-athlete females aged 30-45 years were randomly divided into an experimental and a control group. The experimental group was subjected to perform aerobic exercise at 60-70% of maximal heart rate for eight weeks, three sessions per week and one hour per session. Blood parameters were measured before the exercise program and after the completion of program by taking 2 ml blood samples from the venous vein of the participants in the sitting position. Finally, t-test was used to compare the pre-test and post-test means of each group and independent t-test was used to compare the two groups at significance of 0.05.
- : After eight weeks of aerobic exercise, there was a significant increase in mean platelet volume and a significant decrease in serum iron and ferritin levels in the experimental group (P <0.05). There was a slight decrease in the number of platelets, white blood cells, granulocytes, monocytes and lymphocytes (P<0.05).
Conclusion: We recommend physical education instructors, athletes and non-athletes to consider iron supplementation during aerobic exercise, and modify appropriate training intensity based on the fitness and age of trainees to prevent risk of anemia.

ABSTRACT
Background and objectives: The present study was designed to determine the effect of blood flow restriction training (BFRT) on follistatin to myostatin ratio, body composition and anaerobic power of trained volleyball players.
Methods: Eighteen trained volleyball players were randomly assigned into two study groups: resistance training with blood flow restriction (BFRT; n=9) and resistance training without blood flow restriction (WBFRT; n=9). The subjects performed trainings three sessions a week, for eight weeks. In each session, barbell squat, leg extension, leg curl and dumbbell lunges were performed in three sets of 15 repetitions, with rest intervals of 30 seconds. Serum follistatin and myostatin concentrations, body composition and anaerobic power were assessed before and after the study. Data were analyzed using the paired sample t-test, Wilcoxon test, independent sample t-test and Mann-Whitney U test. All statistical analyses were done in SPSS (version 22), and a P-value of less than 0.05 was considered statistically significant.
Results: Follistatin levels increased significantly (P=0.001), while myostatin levels decreased significantly in both groups (P=0.001). Follistatin to myostatin ratio increased significantly in both groups (P=0.001). Although body fat percentage decreased in both groups, it did not differ significantly between the two groups (P=0.28). Moreover, anaerobic power increased significantly in both groups (P=0.001), but this increase was more profound in the BFRT group (P=0.001).
Conclusion: Based on our findings, blood flow restriction can be applied as remarkable approach to boost body adaptation responses to resistance training.

Abstract
Background and objectives: Elevated blood lipids and physical inactivity are known risk factors of atherosclerosis. The objective of this study was to compare effects of four weeks of high-intensity intermittent training (HIIT) and continuous walking on atherogenic indices of obese middle-aged men.
Methods: Study population consisted of 36 male teachers aged 35-50 years, with mean body mass index (BMI) of 30.7 ± 3.5 kg/m2 who were working in the city of Galikesh, northeastern Iran. The subjects were enrolled via purposeful sampling and were randomly divided into two experimental groups and a control group. Before and after the intervention, anthropometric characteristics (height, weight and BMI) and blood pressure of each subject were measured. Fasting blood samples were taken from the left brachial vein 12 hours before the first exercise session and 12 hours after the last exercise session to determine lipid profile. Data were analyzed using SPSS 18 at significance level of 0.05.
Results: The four-week walking exercise significantly decreased serum levels of low-density lipoprotein-cholesterol (LDL-C) (P=0.001) and triglyceride (P=0.001). In addition, the HIIT program significantly increased high-density lipoprotein level (HDL-C) (P=0.004) and significantly reduced LDL-C (P=0.049), LDL/HDL (P=0.002), triglyceride (p=0.01), BMI (P=0.027) and blood pressure (P=0.002). In addition, the results of ANOVA and (Scheffe test) showed a significant increase in HDL-C (P=0.042) values and a significant decrease in VLDL-C (P=0.032), LDL/HDL (P=0.041), triglyceride (P=0.024), BMI (P=0.048) and blood pressure (P=0.016) of HIIT group compared to the control group.
Conclusion: Our findings indicated that HIIT has beneficial effects on some risk factors of atherosclerosis and cardiovascular disease.
