Akrami Mohajeri F. 1 6 2012 11 2 93 102 05 06 2012   Background and Objectives : Since chemokines expression is one of the most inflammatory responses to injury in the myocardium , this project was aimed to find out the pattern of expression of SDF-1 and IP-10 in dog model of experimental ischemia to extend the results of this model to clinical applications.   Material and Methods: In this experimental study eighteen male dogs aged (6 - 12 months), were randomized in three groups. 1: infarction , Left Anterior Descending Coronary Artery (LAD) was ligated. 2: sham, received the same surgical procedure, excluding LAD ligation. 3: control, was held intact in the same condition. Blood samples were harvested 24 hours before operation, at the time of ligation, 2, 24 and 72 hours and 7 and 28 days after ligation in all groups and serum level of these chemokines was measured by means of ELISA test.   Results: In infarction group the serum level of IP-10 was significantly increased (p ≤ 0.05) at the 2, 24 and 72 hours after MI and reached at peak after 2 hours. In this group, serum level of SDF-1 α at 24 and 72 hours and 7 and 28 days after MI was significantly increased (p ≤ 0.05). The peak of increase was seen in the 72 hours after MI.   Conclusion: U pregulation of angiostatic factors, such as IP-10, in the first few hours following injury may inhibit premature angiogenesis. Suppression of IP-10 synthesis during the healing phase may allow formation of the wound neovessels, whereas high plasma levels of SDF-1 α are clinically associated with start of angiogenesis activities.   Key word: SDF-1α , IP-10, Experimental MI, Dog, Chemokine   Funding: This research was funded by both Rafsanjan University of Medical Sciences and Faculty of Veterinary Medicine of Shiraz University.   Conflict of interest : None declared.   Ethical approval: The Ethical Committee of Rafsanjan University of Medical Sciences approved the study.     How to cite this article : Ghalebi S.R, Hassanshahi G.H, Tabatabai Naini S.A, Esmaeili Nadimi A, Vazirinejad, Rezaeian M, Shamsizadeh A, Akrami Mohajeri F.

Momtazi F. 1 6 2012 11 2 103 114 05 06 2012   Background and Objectives : Medicinal plants have many therapeutic properties including antimicrobial effects with minimum side effects. The purpose of this study was to investigate the antibacterial effects of alcoholic extracts of three medicinal plants Rosmarinus officinalis, Hypericum perforatum, and Carthamus tinctorius on the growth curve of E.coli O157 . This strain is one of the most dangerous bacteria among gasterointestinal pathogenic micro-organisms.   Material and Methods : Leaves and dried flowering branches of rosmary, hypericum and carthamus were used for preparing various concentrations (0.2, 0.3 and 0.4 gr/ml) of alcoholic extracts. The antibacterial effects of these extracts against E.coli O157 were investigated utilizing well assay technique and spectrophotmetery. Statistical analysis was carried out by analysis of variance (ANOVA).   Results : At the first three hours of the experiment, alcoholic extraction of rosmary had an inhibitory effect at all three concentrations comparing to the other two extracts. The hypericum extract showed the least effect at this stage. However, after the first stage of treatment, the reverse results were observed so that E.coli O157 had the lowest growth rate at the presence of hypericum extract.   Conclusion : Based on the findings of this study, rosmary extract had a stronger antimicrobial effect and the other two extracs did not have substantial antibacterial effect on E.coli O157 although, inhibition zones were previously determined. Further investigations in this regard may shed more light on the field of clinical applications af medicinal plants for treatment of infectious diseases.   Key words: Rosmarinus officinalis, Hypericum perforatum , Carthamus tinctorius, E.coli O157, Growth curve     Funding: This research was founded by Ferdowsi University of Mashhad.   Conflict of Interest : None declared.   Ethical approval: The Ethics Committee of Ferdowsi University of Mashhad approved the study .   How to cite this article : Mashreghi M, Momtazi F .

Given the necessity of dealing with this issue in the medical education curriculum of our country, Iran, the aim of the present article was to determine the different dimensions of socially accountable medical schools.   Materials and Methods : In this review study, the Pubmed (http://www.ncbi.nlm.nih.gov/pubmed), Google scholar (http://scholar.google.com/) and Highwire (http://highwire.stanford.edu/) search engines were searched using “socially”, “accountable”, “medical” and “school” as the keywords. This search strategy retrieved 13 articles. Furthermore, it was tried that by altering the search strategy plus searching the reference lists of the retrieved articles, the most relevant and up-to-date articles were determined.   Findings and Discussion : Evidences suggest that a social accountable medical school is a school in which educational, research, health and medical care programs are revised based on the relevant priorities of a society including health requirements and ethical guidelines. Moreover, the selection criteria of academic members and students plus appraisal programs of medical schools are done in a way that accountability in front of society is considered at the center of attention.   Conclusion : Accountability in front of the societies' needs is one of the most important priority in revising medical education around the word. It is necessary that this goal is also adopted by other health sciences' schools.     Key words : Socially, Accountable, Medical, School     Funding : This study did not have any sources of funding.   Conflict of interest : The author is the editor-in-chief of the Scientific Journal of Rafsanjan University of Medical Sciences.    How to cite this article : Rezaeian M.

Nekoie Moghdam M. Jannati A. Pourshaaban Mazandarany M. 1 6 2012 11 2 179 184 24 06 2012   Background and Objectives : Children are very sensitive against any heavy metal’s pollution in the food chain. Therefore, aggregation of high concentration of lead in their blood leads to anxiety. This study looks at lead levels in candy i chocolates and chewing gums which are subject to substantial consumption by children and to announce precautionary warnings where deemed necessary .   Materials and Methods: This cross sectional study was conducted in summer 2009 . Different types of candies , chocolate s and chewing gums in the city of Kerman were chosen as sample s . For this purpose, 26 types of chocolate and candy in Kerman 78 and 24 varieties of the 8 brands of gum were prepared. After preparing the samples, their lead levels by atomic absorption spectrophotometer type flame model PMQ100-X Philips was measured. Descriptive data collected were reported as mean and standard deviation.   Results : Results showed that the minimum amount of lead in samples of chocolate and candy was 3.18 µg⁄g that was related to 4 samples of candy and chocolate made in Iran named Melody milk chocolate and Aydin Caroline chocolate, Neschfi Aydin candy and Honey Akvan candy . The maximum concentration of lead was 5.22 µg⁄g that was related to the fruit sample named Anata cherry candy . The average lead in all sample of chocolate was reported at 3.318 µg⁄g. The maximum amount of lead in gum sample was 27.20 µg⁄g that was related to the one Turkish gum named Relax and the least amount of lead (3.20 µg⁄g) was related to the South Korea gumes named Banana Orion and Lotte Spout and also Iranian gum named Avijeh. The average amount of lead in the samples of gum was 4.576 µg⁄g.   Conclusion: Since the total amount of lead in samples tested over the limit set by the Food and Drug Adminstration of America FDA (1 μg/g), it is therefore recommended that health care and more control be exercised to prevent the introduction of new products containing high lead concentration. Producers must further be made to comply with set standards and limits .   Key words: Lead, Candy, Chocolate, Chewing gum, Children, Kerman     Funding: This research was funded by Kerman University of Medical Sciences.   Conflict of interest: None declared.   Ethical approval: The Ethic committee of Kerman University of Medical Sciences approved the study.     How to cite this article : Malakootian M, Nekoie Moghdam M, Jannati A, Pourshaaban Mazandarany M .
