Background: Adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. Despite immunostimulatory properties, the use of bacterial lipopolysaccharide (LPS) as an adjuvant has been hampered due to its toxicity and pyrogenicity. Brucella abortus LPS is less toxic and has no pyrogenic properties compared to LPS from other gram nega...
Background : Propylene glycol (1,2-propanediol, PG) is a commonly used solvent for oral, intravenous, as well as topical pharmaceutical preparations. While PG is generally considered to be safe, it has been known that large intravenous doses given over a short period of time can be toxic. Objective: To evaluate the effect of PG in sepsis induced by the bacterial endotoxin lipopolysaccharide (LP...
introduction: in the present study, the effect of an inducible no synthase (inos) inhibitor, aminoguanidine (ag) on lipopolysaccharide (lps)-induced memory impairment and oxidative stress and inflammation parameters was evaluated. materials and methods: the rats were divided into 5 groups and treated: 1) control (saline), 2) lps (1 mg/kg), 3-5) ag 50, 100 and 150mg/kg 30 min before lps injectio...
In the present study the protective effect of Nigella sativa (N. sativa) on synaptic plasticity impairment induced by lipopolysaccharide (LPS) in rats was investigated. Fifty-eight rats were grouped and treated as follows: 1) control (saline), 2) LPS, 3) LPS-N. sativa, and 4) N. sativa. In a Morris water maze test, the escape latency and travelled path to find the platform as well as time spent...

Objectives: Bone marrow-derived mesenchymal stem cells (BMSCs) are considered to have potential clinical application value in the treatment of acute lung injury (ALI). Myeloid-derived growth factor (MYDGF) can promote proliferation cell. We hypothesized that MYDGF may play a role reducing vitro and vivo through bone marrow cells. Methods: An model lipopolysaccharide (LPS)(MLE-12) was establishe...
conclusions vaccine based on the conjugation of p. aeruginosa pao-1 lps with dt increased anti-lps antibodies and had a significant potential to protect against pseudomonas infections. background treatment of pseudomonas aeruginosa pao-1 infections through immunological means has been proved to be efficient and protective. objectives the purpose of this study was to produce a conjugate vaccine ...
Background: Activation of inflammatory cells can cause more chemicals induced-hepatotoxicity. Aflatoxin B1 (AFB1) is a fungal toxin that induces acute hepatotoxicity in humans and animals. This study was conducted to examine the effect of co-exposure LPS and various aflatoxin B1 doses on the damage hepatic parameters in isolated perfused rat liver. Methods: Thirty-two male wistar rats (250-3...

background: camellia sinensis and zataria multiflora as the potent antioxidants and anti-inflammations are crucial in the management of wound therapy. lipopolysaccharide (lps) was used for the proliferative potential on fibroblast cells and induction of inflammatory mediators. objective: we examined the effects of lps and herbal extracts combination in order to identify their mechanisms of acti...
