Background and Objective: Infection with HBV is the most common chronic viral infection and mortality in children. Prevention of this infection with vaccination is vital. This study was done to compare the antibody level in post hepatitis B vaccination in children with 12-15 and 21-24 months age. Materials and Methods:This descriptive study was carreid out on 186 children with 12-15 (group I) and 21-24 (group II) months age who had not infected with hepatitis B infection in, Bandarabbas Iran during 2009. The parents were HbsAg negative, without immunodeficiency diseases and did not receive hepatitis vaccination, blood or blood products transfusion. Age, gender, birth weight, breast feeding duration and gestational age were recorded for each child. Hepatitis B antibody level was measured with ELISA method. Data were analyzed using SPSS-16 and student t-test. Results: Antibody level in group I (231 mIU/ml) was significantly higher than group II (142.9 mIU/ml) (P<0.05). There was not significant differences between males and females. Antibody level was not significantly corrolated with body weight, gestational age and breast feeding duration. Antibody level lower than 10 mIU/ml were observed in 4.34% of group I and 20.8% of group II. This differnce was significant (P<0.05). Conclusion: This study showed that the protective effect of vaccination reduced after six months of final dosage.

Background and Objective: The prevalence of behavioral disorders in children with mentally ill parents are higher compared with children of healthy parents. This study was carried out to assess the behavioral disorders in children with major depressive mothers. Materials and Methods: This case – control study was done on 50 children (6-11 years) of mothers with major depressive as case group and 50 children of healthy mothers as controls in Bandar Abbas, Iran drung 2009. With psycological interview, DSM-4-R and Beck tests, deprsion in mother were confirmed. The psycological health of control mothers were confirmed using Minnesota multiphasic personality inventory (MMPI) and questionnaire health general (QHG). The behavior disorders of children in two groups were compared using Achenbach child behavior questionnaire. Data were analyzed using SPSS-17, Chi-Square and student’s t tests. Results: Somatic complains, anxiety and depression, social problems, thought problems, externalization, internalization and antisocial behavior scores, were significantly higher in cases compared to controls (P<0.05). No significant differences in isolation and attention behavior were noticed between cases and controls. Conclusion: Behavior disorders in children with depressive mothers are common.

Background and Objective: Viral upper respiratory tract infection and cold drugs consumption is prevalent among children. These drugs have no effect on disease improvement, but it may also have accompanied with many side effects. This study was conducted to compare the effect of honey and diphehydramine on the alleviation of cough in 2-5-year-old children with viral upper respiratory tract infection. Materials and Methods: This double-blind clinical trial study was carried out on 170 children (60 boys and 66 girls) aged 2-5 years old with viral upper respiratory tract infection who were taken to the pediatric clinic of Shariatee hospital in Bandar Abbas, Iran during 2010. Children demographic charactrastics were including age, gender, period of illness, vaccination history, weight, growth, overall health, and cardiopulmonary examinations. Patients were randomly divided into two groups of 63 children receiving honey (three times a day and the last dose an hour before bed) and diphehydramine syrup (5mg/kg/BW). Two days later, subjects were examined again for the severity and frequency of coughs during day and night. Data were analyzed using SPSS-19, independent t-test and chi-square test. Results: Mean±SD of the age of children was 45.21±11.39 and 43.98±11.95 months in honey and diphenhydramine groups, respectively. The frequency and severity of night coughs was lower in the honey group (97.4%) as compared to the diphenhydramine group (58.7%) (P<0.02). The frequency and severity of daily coughs was lower in the honey group (84.1%) while it was lower in 58.7% of the diphenhydramine group (P<0.01). Conclusion: This study showed that honey is more effective than diphenhydramine in the alleviation of cough caused by viral URTI in 2-5-year-old children.

Background and Objective: Diabetes mellitus cause learning, memory and cognitive skills disorders in the long term. This study was conducted to determine the protective effect of silymarin on the learning and memory deficiency in streptozotocin-diabetic rats. Materials and Methods: This experimental study was conducted on 40 male Wistar rats weighing 240-300 grams. The rats were randomly allocated into 5 groups: control, silymarin -treated control (100 mg/kg), diabetic, and two silymarin -treated diabetic groups (50 and 100 mg/kg). Silymarin was daily administered (i.p. and daily) ten days after streptozotocin injection for 4 weeks. Finally, initial (acquisition index) and step-through latencies (retention and recall index) were measured using passive avoidance test and alternation behavior percentage as an index of spatial memory was determined using Y maze. The level of malondialdehyde in the homogenate hippocampal tissue of the animals brains was measured. Data were analyzed using Sigma Stat-3.5, one-way and two-way ANOVA, Tukey, and Kruskall-Wallis tests. Results: A significant reduction of STL was observed in diabetic (P<0.01) and silymarin-treated (50mg/kg) diabetic (P<0.05) groups and this parameter was significantly higher in diabetic group receiving a high dose of silymarin compared to diabetic group (P<0.05). Meanwhile, alternation percentage in diabetic animals was significantly lower than control group (P<0.05) and this index did not show a significant difference in silymarin-treated diabetic groups in comparison with diabetic group. In diabetic rats, there was a significant increase in the tissue level of malondialdehyde (P<0.05) and silymarin treatment with dosage of (100 mg/kg) significantly reduced the level of MDA (P<0.05). Conclusion: This study showed that although long-term administration of silymarin at a high dose (100 mg/kg) affects the ability to store data in memory and to recall it in diabetic animals in passive avoidance test, it does not improve short-term spatial memory in diabetic animals. The beneficial effects of silymarin may be via attenuation of lipid peroxidation in hippocampus tissue.

Background and Objective: Paraoxonase-1 is an important factor in preventing lipid oxidation and formation of oxidized low-density lipoprotein. There are conflicting reports on the impact of physical activity on serum level of Paraoxonase-1. This study was done to determine the effect of four weeks of endurance training on serum level of Paraoxonase-1 and lipid profile in non-athlete obese men. Method: In this clinical trial study, sixteen obese healthy non-athletic men randomly divided into intervention and control groups. Subjects in interventional group were practiced endurance running periodic for four weeks, three sessions a week with 65-80% of maximum heart rate. Blood samples collected 48 hours perior the first and 48 hours following the final training. Serum level of Paraoxonase-1 and lipid profile including cholesterol, triglycerides, low-density lipoprotein and high-density lipoprotein were measured by ELISA method. Results: At the end of the training, the serum level of of paraoxonase -1 increased 15.57% (P<0.05) in interventional group and non-significantly reduced in control group (19.25%). The serum level of serum Paraoxonase-1 in interventional group significantly increased compared to controls (P<0.05). The serum level of low-density lipoprotein in interventional group significantly reduced in comparision with controls (P<0.05). Conclusion: 4 weeks of endurance training increased serum level of paraoxonase -1 and decreased low-density lipoprotein in non-athlete obese men.

Background and Objective: MIRU-VNTR typing is currently one of the most frequently-used standardized genotyping systems in molecular epidemiology of tuberculosis in the world. This sudy was done to determine the Mycobacterium tuberculosis genotyping by MIRU-VNTR method. Methods: This descriptive study was done on sputum, gastric lavage clinical specimens of 53 tuberculosis suspected patients. Fifty-three isolates were identified by 16S rRNA and Rv-typing followed by RD typing. They were then subjected to a 12-locus (ETRA, ETRB, ETRC, ETRD, ETRE and ETRF, MIRU-10, MIRU-26, MIRU-39, MIRU-30 plus QUB-11b) MIRU-VNTR typing system. Results: In MIRU-VNTR typing, forty-four types were identified with 13 isolates classified in 4 clustered and the remaining 40 isolates representing 40 orphan patterns. In comparative analysis of MIRU-VNTR loci, MIRU-26 with 7 alleles displayed the highest diversity level (Simpson’s diversity index = 0.767. Out of the 53 isolates, only one was identified as Mycobacterium bovis. All the remaining isolates were characterized as Mycobacterium tuberculosis. None of the samples was affected to Mycobacterium complex strain. No evidence of either double or co-infection of the patients with more than one species/strain was detected. Conclusion: While the genomic diversity observed by MIRU-VNTR typing sounds extensive, the population genomic structure on the whole however, seems to be homogenous. Recent transmission between studied patients does not appear to be a frequent event as only 13 isolates representing 4 MIRU-VNTR types, were assumingly epidemic.
