The treatment of supraventricular arrhythmia include wide range of medical intervention, but ideal drug for treatment of this kind of arrhythmia is yet to be developed. Pharmacological interventions due to their adverse side effects and the possibility of proarrhythmic effects are usually ineffective in treating these conditions. Herbal remedies are suitable alternatives for synthetic drugs, due to their availability, minimal side effects and lower price. Pharmacological studies and traditional medical literature point to the cardiovascular effects of the Achillea Santolina in many instances. In present study, we used isolated heart of langandrof rats as an experimental model to determine the effect of various concentrations of the methanol extract of Achillea santolina (2×10^-7, 2×10^-9, 2×10^-10 W/V) on the electrophysiological properties of the isolated heart. Results of this study show a significant depression of WBCL, AVCT and ERP and non-significant increased in time constant of recovery (trec). It may be therefore be considered a potential role for anti-arrhythmic effect of Achillea Santolina in suppression or treating supraventricular tachyarrhythmia.

Low birth weight (LBW) is the main known determinant mortality in under 1 year old children particularly in neonates. The aim of this research is to study the rate of LBW and evaluation of some effective factors in LBW, such as: Difference races, residential conditions, maternal age, parity. This research is analytic-descriptive and cross-sectional study. The study population consists of 2183 newborns that are given birth in Dezyani Hospital during 1996. These samples were chosen by systemic randomized technic (3:1). Information was gathered by a questionnaire. The findings show that LBW rate was 6.3% in population under study, which in male and female newborns were 5.7% and 6.9% respectively. The LBW rates in newborns with mothers age?18 years old and those with ?35 years were 1.8% and 1.4% folds higher than LBW rates for newborns with mothers age 19-35 years. The LBW percentage for primiparous women were 1.9 folds to multiparous who had 2-4 deliveries. LBW rates for newborns with Systanie race were approximately 1.8 folds higher than newborns with Torkman ethnic. The results of this study indicate factors such as: Maternal age, race, parity, affect on LBW rates.

Background & Objective: Rubella vaccine is prepared with live virus thus if it injects during abstinence period, it can cause fetal risks. The aim of study was to evaluate rubella IGM among infants of women who were vaccinated against rubella during 3 months pre-or post-conception (abstinence period). Materials & Methods: This cohort study was done on 253 mothers, including 116 mothers as cases and 137 mothers as controls. The case group inadvertently had received MR vaccine (RA27/3) during abstinence period. The control group selected randomly from similar delivery center that admitted for delivery. The background and confounding factors was matched between the control and case groups. In both groups after delivery, cord rubella IGM was measured by ELISA for serological diagnosis of infant infection. Data was analyzed by Chi-square and T-student tests. Results: The findings showed that the number of positive IGM infant was similar in both groups (One positive IGM in each group). In spite of no significant difference between the case and the control groups, the maximum theoretical risk in this study was 4.392% (RR=1.091 95% CI=0.271-4.392). Conclusion: Although no significant difference was found from the point of infants with an IgM+ serology in two groups, according to the risk ratio obtained in this study, we still recommend vaccination should be avoided during abstinence period.

Background and Objective: Child Sexual Abuse (CSA) is a very serious problem all over the world with widespread and often unrecoverable negative consequences for victim, family and the society. Significant proportion of victims reported abused sexually when they were younger than 7 years. This study was done to evaluate the knowledge and attitude of pre-school girls about sexual abuse prevention in Gorgan during 2016.
Methods: In this descriptive study, 56 pre-school girls with mean age of 76.13±3.87 months (6.34 years), who were chosen through systematic random sampling, among the files of the households with
a pre-school age girl from two health centers in Gorgan, north of Iran during 2016. The Personal Safety Questionnaire- Persian version (PSQ-P) including 12 questions was used to test children’s sexual abuse prevention knowledge and attitude by interview method.
Results: Out of  the 56 children studied, only 9 children (16%) knew all three private parts and of these, only 2 children (3.5%) knew the correct name for all three parts. 80% of children believed that if the perpetrator would ask them to keep touching the private parts as a secret, they should not inform another person. 48% of them did not choose appropriate avoidance responses during inappropriate touching of private parts. 43% of them reported that they do not like their private parts and the appropriate touch of the private parts was not allowed by most children too.
Conclusion: Most pre-school girl children had no proper knowledge and attitude about the sexual abuse prevention, indicating highlights shortcomings in prevention educations at different levels of society.
