Abstract

Background and objectives: Historically, herbs and plants have been used for their therapeutic properties in the form of flavors and preservatives. Recently, the application of medicinal herbs has increased considering their numerous benefits and minimum side-effects. Treatment of bacterial infections is currently a major challenge in the healthcare systems across the world. The present study aimed to assess the bacterial effects of Zingiber officinale, Aloysia citrodora and Artemisia dracunculus essential oils on the survival of standard Gram-positive and Gram-negative bacterial strains.
Methods: In the present experimental study, we evaluated the effects of Tarragon (A. dracunculus), Ginger (Z. officinale) and Lemon Beebrush (A. citrodora) essential oils on 6 strains of Staphylococcus aureus, Klebsiella spp, Salmonella typhimurium, Staphylococcus epidermidis, Proteus spp and Corynebacterium diphtheriae. The well-diffusion method was applied to assess the antibacterial properties of the essential oils. Moreover, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) tests were used to determine the bacterial and inhibitory concentrations of the extracts.
Results: MIC and MBC results demonstrated that the ginger extract (0.125 mg/mL) had the most significant impact on Staphylococcus aureus, Salmonella typhimurium, and Staphylococcus epidermidis. Furthermore, tarragon extract (0.03125 mg/mL) had the most significant effect on Staphylococcus aureus, Proteus spp, and Corynebacterium diphtheriae. The antibacterial effects of these essential oils were not observed on other bacteria.
Conclusion: Medicinal plants have long been used for their therapeutic properties. According to the results, ginger and tarragon extracts are effective combinations for the treatment of the infections caused by Gram-negative and Gram-positive bacteria.

Abstract

Background and objectives: Bacterial antibiotic resistance is a major issue in the process of infectious disease treatments. The aim of this study was an evaluation of the antibacterial activity of Punica granatum flower extract against several gram-negative and positive clinical bacterial isolates.
 
Methods: An adequate dried flower of an endemic mature Punica granatum plant was used for extraction. The standard strain of several gram negative and positive bacteria was chosen for this study, as well as some distinguished clinical strains such as Pseudomonas aeruginosa and Enterococcus spp. In order to indicate the antibacterial effect of Punica granatum mature flower, well-diffusion method was done for each bacterium of the extraction of the flower, so that zone inhibitions can be reported. MIC and MBC test was done.
 
Results: Disc diffusion test was done and the greatest zone inhibition Shigella was 39 mm and then Salmonella typhimurium 13.1 mm. The lowest antibacterial effect of P. granatum extraction was gained on Proteus with 6 mm of zone inhibition. The Highest MIC and MBC effect was obtained from antibacterial evaluation on S. typhimurium and S. epidermidis.
 
Conclusion: the antibacterial activities of medicinal plants, pharmaceutical companies are just using medicinal plants in association with synthetic drugs in order to obtain better results. Setting up a more analytic test on medicinal plants same as HPLC test could be the next stage of this study in order to reach to a higher reliance of medicinal plants antibacterial activities qualification So That we could combine them with synthetic drugs and improve their efficiency.

Abstract

Background and Objective: Cancer immunotherapy combined with other common treatments can be an effective way to overcome cancerous cells. The purpose of this study was to investigate the effect of Freund Adjuvant on breast cancer in the BALB/c model of mice.
Material and Methods: Twenty female inbred 6–7-week-old- BALB/c mice were randomly divided into two groups of Test and Control, each containing 10 mice. Breast cancer was induced by injecting106 4T1 cells into the right flank region of mice. After the tumors were palpable; animals were immunized three times by intraperitoneal (IP) injection of Freund adjuvant in the test group and phosphate buffered saline (PBS) in the control group at same condition. During the study; tumor growth, body weight, and survival percentages in mice were measured by using the caliper method, and mortalities were recorded. Results were tabulated using Excel, and Graphpad Prism Version 8. Data were analyzed using One-Way ANOVA and T-test and the significance level for statistical tests was considered p≤0.05.
Results: The results showed that tumor mice given Freund Adjuvant had a significant reduction in tumor size compared to the control group (P=0.01) and no significant weight difference was observed between the two groups (P=0.4). Furthermore, Kaplan Meier showed that the survival of the mice in the Freund Adjuvant group was significantly increased compared to the control group (P=0.009).
Conclusion: This study showed that Freund Adjuvant may play an important role in improving the function of the immune system for cancer immunotherapy.
