Abstract
Aim and objective: Today, the main treatment for bacterial infections is the use of antibiotics, but due to side effects and increased antibiotic resistance, the use of complementary or alternative methods to treat infectious diseases has become particularly important.
Material and Method: In this study, prodigiosin pigment was produced by a strain of Seratia marcescens and its antibacterial effect on a number of gram-positive and gram-negative pathogenic bacteria was investigated by determining the MIC and MBC of the pigment. The synergism effect of pigment with a number of common antibiotics was also investigated.
Results: The results of this study showed that produced prodigiosin, at concentrations of 32, 64, 256 and 512 μg / ml could inhibit the growth of Bacillus cereus, Staphylococcus aureus, Escherichia coli and Klebsiella oxytoca respectively. The study of synergism phenomenon also showed that, this pigment has a synergistic effect with the antibiotics oxacillin, ceftriaxone and vancomycin.
Conclusion: According to the results, it seems that gram-positive bacteria are more sensitive to produced prodigiosin and also the synergistic effect of this pigment is mainly with antibiotics that affect the cell wall of bacteria. If the harmlessness and non-toxicity of this pigment is proven in living animal and human models, we can hope that this pigment will be used as a complementary drug or even as an alternative to antibiotics.

Abstract
Background and Aim: Pseudomonas aeruginosa is a Gram - negative bacterium and one of the most important opportunity seeker pathogens in hospital infections that are typically obtained simultaneously. This study was carried out with the aim of examining the synergistic effects of the antibiotic ciprofloxacin and extracts of Morus nigra in the control of the Pseudomonas aeruginosa biofilm.
Materials and Methods: In this study, synergistic effects of ciprofloxacin antibiotic and Morus nigra extracts were used to inhibit the growth and biofilm formation of the 10 isolates of multi drug resistant P. aeruginosa. Disc diffusion method has been used to determine antibiotic resistance. To examine the synergistic antimicrobial activities between Morus nigra extract and ciprofloxacin, Checker titration method was used to calculate the fractional inhibitory concentration (FIC). The effect of Morus nigra extract, ciprofloxacin antibiotics and the combination of both of them on the expression level of pslA gene was investigated by Real time PCR.
Results: Morus nigra extract showed antimicrobial effect against MDR P. aeruginosa strains. The use of this extract in combination with ciprofloxacin had an additive effect on inhibition of growth of P. aeruginosa and at least 60% reduction in biofilm formation of test isolates was achieved (P˂0.05). Also, Morus nigra extract alone and in combination with ciprofloxacin antibiotic decreased the pslA gene expression levels.
Conclusion: The present results are promising in regard to the possibility of using Morus nigra extract to increase the effect of sinus for antibiotics infections. The use of this extract, or instead of antibiotics, may be a way of reducing the use of antibiotics, thus reducing the side effects and treatment costs of infectious diseases.

Abstract
Background: Today, the main strategy for the treatment of bacterial infections is the use of antibiotics, but due to side effects and increased antibiotic resistance, the use of complementary or alternative methods to treat infectious diseases has become particularly important.
Methods: Aqueous and alcoholic extracts of Peganum harmala seeds were prepared by soaking method. The MIC and MBC of the extracts were determined for one strain of Streptococcus sanguinis. The synergistic effect of the produced extracts with the antibiotics ampicillin, erythromycin and clindamycin was also investigated.
Results: The results of this study showed that aqueous extract of Peganum harmala in concentrations of 1250 and 2500 μg / ml, and alcoholic extract of this plant in concentrations of 625 and 1250 μg / ml have inhibitory and lethal effect on the studied bacteria, respectively. In the study of the phenomenon of synergism between aqueous and alcoholic extracts with the studied antibiotics, which was done by the checkerboard method, it was found that the alcoholic extract of this plant has synergistic effect with the antibiotic clindamycin.
Conclusion: Alcoholic extract of Peganum harmala seeds can show a good antibacterial effect against Streptococcus sanguinis, one of the important species living in the mouth and the cause of endocarditis. Further research on the extraction and purification of effective compounds from this plant and the study of therapeutic effects or its possible side effects in the living organism, can be a step towards the use of herbal medicines as a supplement or alternative to common antibiotics.

Abstract
Introduction: Health tourism, as a significant branch of the tourism industry, has gained substantial attention from numerous countries in recent years. This industry not only contributes to economic development and job creation but also improves access to quality healthcare services. In the Islamic Republic of Iran, despite possessing considerable capabilities in various medical and therapeutic fields, health tourism has not received the dedicated attention of lawmakers, and there is a lack of specific legislative frameworks in this area.
Methods: This study utilizes descriptive and analytical research methods to analyze the status of health tourism within the legal framework of the Islamic Republic of Iran. Content analysis was employed to extract and review relevant high-level documents and regulations pertaining to health tourism. The study commenced with the collection of legal documents and regulations related to health tourism, followed by a comprehensive content analysis of these resources to assess the extent to which existing laws support health tourists.
Results: The findings reveal that health tourism has not been explicitly addressed in Iran's legal system. While the term "health tourism" is not directly mentioned in the laws, it is possible to provide legal protections for health tourists by referencing general principles and legal norms. Additionally, this study examines the economic implications of health tourism, including its impact on job creation and revenue generation.
Conclusion: The study concludes that for the successful development of the health tourism industry in Iran, it is essential to reinforce the legal infrastructure and establish specific legal protections. It is recommended that laws and regulations be formulated explicitly to anticipate and provide the necessary support for health tourists, ensuring their legal security as travelers in this sector.
