- چکیده: مقدمه و هدف: رازیانه یک گیاه دارویی و آروماتیک است. آزمایشهای مختلف پزشکی در شرایط آزمایشگاهی و در شرایط زنده به طور متقاعدکنندهای توانایی ضد قارچی ، ضد باکتریایی، آنتی اکسیدانی، ضدترومبوز و فعالیت محافظتی در کبد را نشان داده است. هدف از این مطالعه بررسی فعالیت ضد باکتریایی عصاره های رازیانه بر روی باکتریهای بیماری-زا است.
روش تحقیق: به این منظور عصارههای اتانولی، متانولی و استونی (از طریق روش خیساندن) بر روی بخشهای مختلف رازیانه (گل، برگ و میوه) آماده شد و فعالیت آنها بر روی برخی گونههای باکتریایی گرم مثبت (استافیلوکوکوس آرئوس، باسیلوس سرئوس) و گرم منفی (سودوموناس آئروژینوزا، اشرشیاکلای) از طریق روش استاندارد دیسک دیفوژن امتحان شدند.
نتایج: یافتهها نشان میدهند که حساسترین باکتری نسبت به عصاره استافیلوکوکوس آرئوس و مقاومترین باکتری سودوموناس آئروژینوزا میباشد. نتایج نشان میدهد که در مورد گل رازیانه عصاره متانولی و استونی به ترتیب بیشترین و کمترین خاصیت ضد باکتریایی را دارند و عصاره اتانولی برگ رازیانه بیشترین خاصیت ضد باکتریایی را دارا هستند و در مورد میوه رازیانه عصاره متانولی و استونی به ترتیب حداکثر و حداقل فعالیت ضد باکتریایی را دارد. در کل نتیجه این مطالعه نشان میدهد که عصاره گل رازیانه نسبت به بقیه اجزا رازیانه خصوصیات ضد باکتریایی بیشتری دارد.
توصیههای کاربردی/ صنعتی: مکانیسم عمل رازیانه به علت حضور ترکیبات فنولی و ترپنوئیدی است. این ترکیبات به طور بالقوه بر روی نفوذپذیری غشای باکتریها اثر میگذارد و در نتیجه باعث مرگ سلول میشود. بنابراین عصاره رازیانه میتواند برای کنترل باکتریهای مقاوم به چندین آنتیبیوتیک مورد استفاده قرار گیرد.- چکیده انگلیسی: Background & Aim: Foeniculum vulgare Mill. (Apiaceae) is a medicinal and aromatic plant. Various pharmacological experiments in vitro and in vivo models have convincingly showed F. vulgare ability in antifungal, antibacterial, antioxidant, antithrombotic and hepatoprotective activities.
Experimental: The purpose of this study was to evaluate the antibacterial activity of extracts of Foeniculum vulgare on the number of pathogen bacteria. For this purpose, ethanol, methanol and acetone extracts (through maceration method) of different parts of the Foeniculum vulgare (flowers, leaves and fruit) were prepared and antibacterial activity was tested against some gram positive (Staphylococcus aureus, Bacillus cereus) and gram negative (Pseudomonas aeruginosa, Escherichia coli) bacterial species through standard disc diffusion method.
Results: The findings showed that the most sensitive bacteria to the extracts was Staphylococcus aureus and the most resistant bacteria was Pseudomonas aeruginosa. According to the gained results in the case of fennel flower and fruits extract, methanol and acetone extract showed the highest and lowest antibacterial activity, respectively, while in the case of fennel leaves ethanolic extract exhibited the most inhibitory effect. In general, the results of this study indicated that the extract of fennel flowers had more antibacterial properties in comparison with other parts of plant.
Recommended applications/ industries: The antibacterial activity of fennel is due to the presence of terpenoids and phenolic compounds. These compounds are potentially effective on membrane permeability of bacteria and thereby cause the cell death. Therefore, fennel extract can be used to control bacteria resistant to several antibiotics.- انتشار مقاله: 12-10-1396

- چکیده:
- چکیده انگلیسی: Background: Addiction and drug misuse is an illness that affects every community in every country. Based on the previous research in many parts of the world, illicit drug use is considered as a well-known risk factor for morbidity, disability, and premature mortality. Although this issue is a hot topic for public health, little studies have looked the epidemiology of substance abuse death and its trends among Iranian society. This study aims to calculate the rate of substance misuse mortality and investigate its trend in Iran. Methods:This research was a cross-sectional study. For doing this study, the demographic and epidemiological data of people who died from substance misuse from 2014-2018 were extracted from Legal Medicine Organization (LMO). Finally, descriptive statistics were used to analyze the data. Findings: 15304 deaths due to drug misuse were recorded in 2014-2018. The substance abuse mortality rate has increased during the study period in men and women. There were significant differences in death rates between men and women. Crude mortality rate was significantly higher among men compared to women. The majority of deaths has occurred in young men aged 30-39 years with high school education and self-employed. Conclusion: The results revealed that death from substance misuse has increased during the study period. This increasing trend was observed in women and men. Further preventive measures, however, should be devised to reduce drug-related deaths. The majority of deaths occurred in young men aged 30-39 years with high school education and self-employed. In our opinion and based on the study results, programs, policies, and preventive measures should be taken to prevent these people from accessing and using the drug.

- چکیده:
- چکیده انگلیسی: Background: Drug abuse is a severe and chronic disorder that leaves morbidity, disability and premature mortality in the society. The study of death due to substance abuse provides useful information for local, national and international administrators. Thus, by identifying the factors that have an impact on overdose-related mortality we can provide suitable intervention for vulnerable groups. The aim of this study was an investigation of mortality rate caused by consumption of narcotic and psychoactive substances in Iran.Methods: In this cross-sectional study, demographic and epidemiological data about all people whose cause of death was substance abuse in March 2014 to February 2015 were collected from Legal Medicine Organization (LMO). Finally, the information that was extracted from two checklists was analyzed by descriptive statistics.Findings: In this study, 2986 cases died from substances abuse were evaluated. Most deaths have befallen in unmarried young men with mean age of 36.9 ± 12.3, in the private locations. The mortality rate of drug abuse in the whole country was 38.4 per 1000000 population. The proportion of mortality was higher in Iranian nationality and in people who had a diploma and less education. History of overdose, suicide, hospitalization in a psychiatric hospital, staying in prison and substance abuse in the family were investigated in the study population.Conclusion: The present study revealed that mortality rate from substance abuse is more among unmarried young men aged 30-39 years with low education level and also in the self-employed group. We suggest that policies should be taken to prevent these people from accessing and using the drug.
