In this study, alginate microspheres containing BCG were prepared at a diameter of approximately 10 microm by emulsification-internal gelation of an alginate-BCG solution dispersed in olive oil using a high rate speed stirrer. The stability of BCG was assayed at 4 degrees C showing that the encapsulated BCG was more stable than free BCG at least for 5(More)
PURPOSE Interleukin-12 (Il-12) as a cytokine has been proved to possess antitumor effects via stimulating the immune system. Non-viral gene delivery systems exhibit low toxicity and are easier to prepare compared to their viral counterparts. In this study, we aimed to prepare plasmid DNA loaded chitosan nanoparticles for expression of Il-12 and to evaluate(More)
AIM Gelatin as a biodegradable, nontoxic and biocompatible natural protein is a good candidate for gene delivery. In this study, pDNA-loaded gelatin nanoparticles were prepared and characterized for the expression of the cytokine IL-12 and anti-tumor effects. MATERIALS & METHODS Gelatin-pUMVC3-hIL-12 nanoparticles were prepared by the ethanol(More)
Bacillus Calmette-Guerin (BCG) is the only available vaccine against tuberculosis. The research for an improved vaccine is currently a very active field of investigation. In the present study, adjuvanticity effect of sterile sodium alginate on subcutaneous BCG vaccination in BALB/c mice was investigated. Mice were vaccinated subcutaneously with BCG plus(More)
Bacille Calmette-Guerin (BCG) is one of the first vaccines administered to the newborns in developing countries. As an alternative to parenteral administration of vaccines, oral vaccines offer significant logistical advantages. Successful oral immunization, however, requires that vaccine antigens be protected from gastric secretions. In the present study,(More)
BACKGROUND Leishmaniasis is a complex disease which presents as visceral, cutaneous and mucocutaneous forms. The current treatment options for this infection are very limited and the immunological state of the host appears to play an important role in the efficacy of the treatment. Immunostimulation through immune response activating agents such as(More)
Effective vaccination against pathogens, which enter the body through mucosal surfaces, requires the induction of both mucosal and systemic immune responses. Here, mucosal as well as systemic immune responses in the lung and spleen of BALB/c mice which were orally vaccinated with a single dose of alginate-encapsulated bacille Calmette-Guerin (BCG) were(More)
BACKGROUND Different methods have been used for BCG vaccination. Alginate microspheres are useful in delivery of vaccines to the gastrointestinal tract by oral route. OBJECTIVE To compare the immune response following oral microencapsulated and subcutaneous (SC) route administration of BCG vaccine in BALB/c mice. METHODS Alginate microspheres were(More)
INTRODUCTION Traumatic Brain Injury (TBI) accounts for the majority of trauma deaths and there has been increased interest in the understanding the role of prognostic factors. C-Reactive Protein (CRP) level increases rapidly in response to trauma. AIM Aim of the present study was to indicate the role of CRP as a predictor of outcome in TBI patients based(More)
OBJECTIVE Inadequate postoperative pain relief after cesarean section can increase complications. In this study, we evaluated the effect of intrathecal betamethasone as an adjunct to bupivacaine on postoperative pain in patients undergoing cesarean section. METHODOLOGY Ninety-nine patients undergoing cesarean section were assigned to one of three groups.(More)
