RESUMO
Background: The aim of this study was to investigate the effects of two types of quran voice, Majlisi or Tartil on IgA, IgM, IgG, C3, C4 and White Blood Cell count.
Methods and Materials: this study was conducted on 60 volunteer students in sabzevar university of Medical sciences. Subjects were divided randomly into 2 groups. In the first group, participants heard to Majlisi voice and in the second group, subjects heard to Tartil voice of Quran for 20 minutes. Blood sampling were done before and after Quran hearing. IgA, IgM, IgG, C3 and C4 were measured by SRID and kit method and white blood cell count was done by cell counter. Data were analyzed using SPSS16 software and U Mann Whitney and Kruskal Wallis tests.
Results: Hearing the Majlisi voice significantly increased the IgG [p=0.032], C3 [p=0.049] and C4 [p=0.004], but it did not change other factors. Hearing the Tartil voice rose significantly gust the IgG [p=0.008] and C3 [p=0.001].
Conclusion: The results of this study shows that hearing to both types of Quran voice [Majlisi or Tartil] can go up the immune system factors and inhance this to encountering some stressful and critical situations.
RESUMO
Background and Purpose: Evaluation of puberty stages is important to assess adolescent health. This study has been done with the aim of determination of the average age of onset of puberty and its relationship with Body Mass Index [BMI] in male students of Sabzevar city in the North East of Iran in 1390.
Methods and Materials: This cross - sectional study was conducted on 252 male students of secondary schools and high schools of Sabzevar, Iran, with the age of 11-18 years who were selected by probability and multistage sampling. Data were collected through a Tanner standardized questionnaire; afterwards, measuring of height and weight and BMI calculation were performed. Data were analyzed in SPSS 15 using chi-square test, t-test, ANOVA and Bonfronie post hoc test, analysis of covariance, Spearman correlation coefficient and Kappa agreement coefficient; significance level was considered as 0.05.
Results: To conduct this study, we selected a group of researchers who were trained for the initiation of project for assessing puberty in male schools in order to increase the accuracy of determining the Tanner stages. Students were examined for their height and weight, size of penis and testicles, and the manner of pubic and axillary hair growth as well as also voice changes. Mean final growth stage of testicles and scrotum [G5 stage], pubic hair [P5 stage], were measured to be 16.40 +/- 1.65 and 16.79 +/- 1.19 years respectively, and their mean BMI at P2 and G2 were 20.96 +/- 4.1 and 19.49 +/- 3.66 kg /m2 respectively.
Conclusion: Regarding to the declining age of puberty and its relationship with BMI, health systems should focus on training programs and encouraging teenagers to begin changing their lifestyle. Age of puberty onset in male students is similar to many other countries but determining the precise status of puberty in Iranian children requires further studies in different provinces, rural and urban areas as well as longitudinal studies.
RESUMO
Background: Adiponectin is an adipocytokine which may be a marker for coronary artery disease and appears to have protective metabolic and anti-inflammatory properties. The purpose of this study was to investigate the relationships between serum adiponectin levels and insulin resistance, blood pressure, and cardio-respiratory function in sedentary men
Methods and materials: In this semi-experimental study, 45 young men, without experience of regular physical activity during the last six months, were selected. After 12 h fasting [at 8 A.M.], blood samples were collected to determine serum levels of adiponectin, insulin, and glucose. Cardio-respiratory function of subjects was estimated using Balke's treadmill protocol and their blood pressure was measured by sphygmomanometer. Data was analyzed by SPSS 16.0 software and the relationships were evaluated by Pearson's correlation coefficient. P value of less than 0.01 was considered statistically significant
Results: Adiponectin levels were negatively correlated with body mass index [r=?0.41, p<0.002], insulin [r=?0.45, p<0.009], glucose [r=?0.27, p<0.007], and HOMA index [r=?0.40, p<0.002], and positively correlated with maximal oxygen uptake [r=0.31, p<0.006]. No significant correlations were observed between adiponectin levels and systolic [r=?0.13, p<0.097] or diastolic blood pressure [r=?0.09, p<0.117]
Conclusions: It appears that in sedentary men, who have lower cardio-respiratory fitness, lower adiponectin levels may be associated with abnormal glycemia, promoting the probability of type II diabetes and cardiovascular disease in these subjects. Also, serum concentrations of adiponectin are directly correlated with cardio-respiratory function, but it appears that there is no correlation between adiponectin levels and blood pressure
