- چکیده:
- چکیده انگلیسی: Herbal compounds with antimicrobial effects are of major considerations because of increasing antimicrobial resistance of pathogenic bacteria. In this study, we investigated the antimicrobial effects of Melissa officinalis L, Plantago major L, Orobancha crenata Forsk, Phoenix dactylifera, Ziziphus mauritiana and Teucrium Polium seed extracts on some human pathogenic bacteria isolated from burn wounds. Disk-diffusion antibiotic sensitivity testing, Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were applied to assess the antibacterial activity of the extracts in comparison to the tetracycline, as a control antibiotic. The extract of the Orobancha crenata showed stonger antibacterial effects than the other herbal extracts on Pseudomonas aeroginosa and Kelebsiela ponomoni. Staphylococcus aureus was the most sensitive one to the Ziziphus mauritiana nucleus extract compared to other herbs. According to the results of this study, it can be concluded that extracts of some native plants of Iran can be appropriate alternative to the existing antibiotics, applicable for prevention of burn infections.

- چکیده:
- چکیده انگلیسی: Prebiotics are known as fermented ingredient with specific health benefits. The two main fermentative substrates of dietary origin are non-digestible carbohydrates and proteins which escape digestion in the small intestine. Beside traditional protocols for production of prebiotics, there are some commercial advanced methods for mass production of prebiotics with acceptable health effects. On the other hand, different types of nondigestible oligosaccharides (NDO) are used in the food and drug industries as functional foods and nutraceuticals due to their prebiotic effects and also immunomodulation effects (ex. SCFA modulate chemokine expression in intestinal epithelial cells). Prebiotics with novel and wide variety of health benefits deal with a bright future for improving society health.

- چکیده:
- چکیده انگلیسی: Strychnine is a toxic alkaloid which might be the source of poisoning with homicidal and suicidal purposes. Eleven fatal cases of strychnine ingestion were considered in this study. Strychnine was isolated from biological samples using the solid phase extraction (SPE) procedure and detected by analytical methods such as thin layer chromatography (TLC), gas chromatography/mass spectrometry (GC-MS) as well as high performance liquid chromatography (HPLC). Eleven cases of strychnine ingestion including 8 men and 3 women with minimum and maximum ages of 17 and 56 years old have been studied. Most of them had an education level of high school and had neither criminal history nor psychological disorders except for 3 cases that were using psychiatric drugs. Facial and ocular congestion, facial cyanosis, lung edema and hemorrhage were found in all of the cases. Hyperemic kidney, brain, liver and meninges and lung collapse were other pathologic findings encountered. Reactive gliosis, subarachnoid focal hemorrhage and 6 cm laceration on the left side of the face were separately found in three cases. Considering highly fatal effects of strychnine and its potential suicidal use, it should be strictly and severely prohibited and watched out for its misuse. On the other hand, the analytical methods used, indicated their reliable, simple, specific and sensible application in forensic and clinical investigations.
