Potential targets of phytochemical immunomodulatory therapy in periodontitis immunopathogenesis: A narrative review.

Introduction: Periodontitis is one of the most prevalent diseases occurring worldwide, and is caused by an imbalance of host immunological defenses and microbiome profile which occurs in the oral cavity. This imbalance leads to irregularity and uncontrolled activities of immune cells, resulting in over-reactivity of periodontopathogens and tissue destruction. To alleviate periodontitis, exact targeting of specific events involving particular cells could be a potential application of immunomodulatory agents.

Enhancement of pyocyanin production by subinhibitory concentration of royal jelly in .

, a multidrug-resistant Gram-negative bacterium, produces pyocyanin, a virulence factor associated with antibiotic tolerance. High concentrations of royal jelly have an antibacterial effect, which may potentially overcome antibacterial resistance. However, in some cases, antibiotic tolerance can occur due to prolonged stress of low-dose antibacterial agents.

Prostaglandin E2 enhances transforming growth factor-beta 1 and TGF-beta receptors synthesis: an in vivo and in vitro study.

The aims of this study were to determine how Prostaglandin E2 (PGE2) locally applied affected the immunodistribution of latent transforming growth factor-beta 1 (TGF-beta1), and how the eicosanoid modified TGF-beta1 release and TGF-beta receptors gene expression in cultured osteoblasts. PGE2 locally delivered on the rat mandible at doses of 0.1 and 0.

The effect of fish oil on bone resorption following pulp exposure in rats.

The aim of this study was to determine whether treatment with fish oil may alter the periapical bone resorption following pulp exposure in rats. Untreated and pulp-exposed animals served as the negative and positive control, respectively. Other pulp-exposed animals were orally treated with fish oil at different concentrations and frequencies.

Effect of high-density lipoprotein on lipopolysaccharide-induced alveolar bone resorption in rats.

Objective: To determine whether treatments with high-density lipoprotein (HDL) may alter the lipopolysaccharide (LPS)-induced alveolar bone resorption in rats.

Materials And Methods: Rats were injected with 500 microg of LPS from Escherichia coli at the alveolar mucosa of lower right first molar once every 2 days for 8 days. The negative and positive control were injected with phosphate buffered saline (PBS) and LPS alone, respectively.
