- چکیده انگلیسی: Background: Awareness of the motives of the students for choosing to study medicine demonstrates their understanding of the nature of this major and their expectations from their future profession. The evaluation of the volume of students who choose this major with wrong motives is necessary for educational planning of professional commitment. This study was conducted to evaluate the motives of choosing to study medicine in the first-year medical students of Tehran University of Medical Sciences.
Methods:This descriptive analytical study was conducted on first-semester medical students of Tehran University of Medical Sciences in the 2014-15 academic year who were selected through census sampling. The data collection tool was a self-administered questionnaire, which included questions on 17 different motives in a Likert scale in addition to demographic characteristics.
Results: Of 131 distributed questionnaires, 124 (93%) were completed and returned. Eighty-six participants (65.61%) mentioned helping others as their main motive for choosing medicine followed by interest in the human body, interaction with people, professional prestige, and starting a good profession after graduation. On the other hand, unfamiliarity with other majors, competition with others, and teamwork were the least important motives.
Conclusions: The students’ motives are mostly altruistic and in accordance with medical professionalism. These motives should be reinforced to enhance professional performance. Moreover, the faculty of medicine should recognize and offer counseling services to students with undesirable motives.- انتشار مقاله: 21-11-1396

- چکیده انگلیسی: Background and aims: Herbal medicines are the major remedy in traditional medical systems and have a great contribution in maintaining human health and preventing many infectious diseases. The aim of this study was to assay antibacterial potential of Marrubium vulgare L. extract against Klebsiella pneumoniae resistant strains to current antibiotics and also GC/MS analysis to better understanding the extract composition. Methods: In this experimental research, 30 K. pneumoniae strains isolated from urine culture of hospitalized patients were used. The essential oil of Marrubium vulgare L. was obtained by hydro distillation for 2 hours using the Celevenger with yield of 75%. Methanolic extract from M. vulgare L. was prepared using Rotary apparatus. In order to determine chemical composition of essential oil, gas chromatography coupled with mass spectrometry (GC-MS) was performed. The minimum inhibitory concentrations and minimum bacterial concentrations were investigated to characterize the antimicrobial activities of this essential oil and its extract. Data were analyzed using analysis of variance (one-way) to determine the statistical differences between different tests. Results: The results showed that K. pneumoniae strains were resistant to 4 or 3 agents including: Ampicillin (65%), Gentamicin (30%), Sulfamethoxazol (25%). The lowest and the highest MIC value of M. vulgare L. extract were 2.5 and 10 mg/mL, respectively. The highest and the lowest MIC value of M. vulgare L. essential oil was 5 and 1/25 mg/m respectively. Conclusion: The present study confirmed that essential oil and extract of this plant could be served as an antibacterial agent in pharmaceutical industry.

- چکیده انگلیسی: Background and aims: Traditionally, plants have long been applied in the treatment of various diseases throughout the history of human life. The antimicrobial activity of plant extracts in the laboratory is studied on Gram positive and negative strains of human infectious agents. The aim of this study was to evaluate the antibacterial activity of Mentha longifolia against important human pathogens. Methods: This was an experimental study and no statistical method was used. The antimicrobial effect of ethanol extracts of Mentha longifolia were investigated on Salmonella typhimurium were determined using broth microdilution method. The broth microdilution method was used to determine the Minimal Inhibitory Concentration (MIC) and the Minimum Bactericidal Concentration (MBC). All tests were performed in Mueller Hinton broth supplemented with Tween 80 at a final concentration of 0.5%. Results: The results showed that the lowest MIC concentration was 5 mg/ml that 1 strain of Salmonella was inhibited. The highest and the lowest MBC values of extract were 40 and 10 mg/ml, respectively. Conclusion: Since the antibiotic resistant bacteria are increasing in the world, replacing the chemical and synthetic antibiotics with natural products is essential. It can be concluded from the results of this study that using herbal plant instead of antibiotics can resolve some antibiotic resistant problems.
