Psychometric properties of the Social Cognitive Theory questionnaire for physical activity in a sample of Iranian adolescent girl students

This research examined the validity and reliability of a researcher-developed questionnaire based on Social Cognitive Theory [SCT] to assess the physical activity behaviour of Iranian adolescent girls [SCT-PAIAGS]. Psychometric properties of the SCT-PAIAGS were assessed by determining its face validity, content and construct validity as well as its reliability. In order to evaluate factor structure, cross-sectional research was conducted on 400 high-school girls in Tehran. Content validity index, content validity ratio and impact score for the SCT-PAIAGS varied between 0.97-1, 0.91-1 and 4.6-4.9 respectively. Confirmatory factor analysis approved a six-factor structure comprising self-efficacy, self-regulation, family support, friend support, outcome expectancy and self-efficacy to overcoming impediments. Factor loadings, t-values and fit indices showed that the SCT model was fitted to the data. Cronbach's alpha-coefficient ranged from 0.78 to 0.85 and intraclass correlation coefficient from 0.73 to 0.90

Evaluation of the role of striatal cannabinoid CB[1] receptors on movement activity of parkinsonian rats induced by reserpine

It has been observed cannabinoid CB[1] receptor signaling and the levels of endocannabinoid ligands significantly increased in the basal ganglia and cerebrospinal fluids of Parkinson's disease [PD] patients. These evidences suggest that the blocking of cannabinoid CB[1] receptors might be beneficial to improve movement disorders as a sign of PD. In this study, a dose-response study of the effects of intrastriatal injection of a cannabinoid CB[1] receptor antagonist, AM251 and agonist, ACPA, on movement activity was performed by measuring the catalepsy of reserpinized and non-PD [normal] rats with bar test. Also the effect of co-administration the most effective dose of AM251 and several doses of ACPA were assessed. AM251 decreases the reserpine induced catalepsy in dose dependent manner and ACPA causes catalepsy in normal rats in dose dependant manner as well. AM251 significantly reverse the cataleptic effect in all three groups [1, 10, 100ng/rat] that received ACPA. These results support this theory that cannabinoid CB[1] receptor antagonists might be useful to alleviate movement disorder in PD. Also continuance of ACPA induced catalepsy in induced catalepsy. Based on the present finding there is an incomplete overlapping between cannabinoid CB[1] receptor agonist and antagonist effects

[ effect of health education program on knowledge, attitude and performance in male primary school students regarding Tinea capitis in Chabahar]

In many parts of the world Tinea Capitis is a public health problem, especially in primary school children. The control of the disease is dependent on patients' education for increasing their knowledge and health. The aim of this study was to evaluate on knowledge, attitude and performance in male primary school students regarding Tinea Capitis in Chabahar in 2007-2008. In this quasi-experimental [case - control] study, 115 primary school students were randomly selected from two primary school in the city of Chabahar. Students were assigned into two groups. Tools and data collection methods were included: questionnaire, check list and laboratory samples of scalp and hair. At the beginning of the research, a pre-test was performed on the students and according to the data obtained, an educational program were prepared and was performed for experimental group. Post-test was done after two months. Data was analyzed using chi-square, Mann-Whitney, Wilcoxon and McNemar tests. The findings showed a significant increase in the knowledge, attitude, performance in experimental group [P<0.001]. In addition, experimental group demonstrated a significant decrease in Tinea Capitis [P<0.01]. The results of this study showed that there is a significant relationship between Tinea Capitis and weight, type of skin and parents' education [P<0.05]. The results of this research show that the risk of Tinea Capitis transmission is a public health problem and health education is a suitable response to this problem

Evaluation of antioxidant activity of methanolic extracts and some fractions of salvia verticillata l. using three different methods

Bradykinin has effects on histaminic response,vessels seepage,cellular reproduction,causing fever, pain and coughs caused by ACE controllers [3,4,6]. Noscapin has controlled Bradykinins contractional effects on guinea pigs trachea and rats vazodofran [5,6]. noscapin stops the secondary effects of eskimi in brains edema, with antagonizing the responses caused by Bradykinin [3,4,8]. considering that opium's alkaloids act as agonist of peptide systems like ankephalins and RAS, its interesting to know the effects of this alkaloids and among them Noscapine on B3 Bradykinin receptors on smooth muscle guinea pig trachea? All variables are reported as mean and standard deviation.We have used pair test and the informations were processed by Excel, Statistical analysis with ANOVA [LSD] SPSS 9. we took diagrams in to consideration and indicated that the contract ional effect of Bradykinin decreased dependent on density, in presence of three different amount of noscapines concentration. In this study we could demonstrate that noscapine interact with Bradykenin as a non competitive antagonist

[Evaluation of treatment prognosis in traumatized anterior teeth in dental schools of Shaheed Beheshti and Tehran during 1995 - 2000]

Background and aim: trauma, as one of the most prevalent tooth accidents in all stages of life, has received a lot of attention. Increasing knowledge about trauma can reduce and prevent its harmful consequences as well as the related costs. The aim of this study was to evaluate treatment prognosis of anterior traumatized teeth among patients referred to endodontics and pediatrics departments of Shaheed Beheshti and Tehran dental faculties during 1995 - 2000

Materials and Methods: in this descriptive and existing data study, a written questionnaire was used for data collection. Files of patients with completed treatment, in endodontics and pediatrics departments of both dental faculties, were investigated. The colleefed data were analyzed by SPSS software

Results: 84% of the studied teeth were maxillary central teeth. The most prevalent etiology for trauma was falling down and the most prevalent type of fracture was that of enamel and dentin without pulpal involvement. The most reported treatment was pulpal and periapical treatment

Conclusion: treatment procedures conducted on the traumatized anterior teeth was acceptable
