Abstract:
Background: Systemic acute inflammation is the hallmark of sepsis and is associated
with multiple organ dysfunction.
Objective: This study investigated the potential of Stingless Bee Honey (SBH) to suppress
lipopolysaccharide (LPS)-induced systemic acute inflammation in rats and to reveal the probable
mechanism of action.
Methods: Rats received 4.6 and 9.2 g/kg SBH for 7 days followed by a single injection of LPS after
which blood samples were taken 6h later.
Results: LPS induced liver, kidney, heart, and lung injury, were manifested by increased serum
transaminases, alkaline phosphatase, creatine kinase, creatinine, and urea, along with multiple histological
alterations, particularly leukocyte infiltration. Pro-inflammatory cytokines were elevated in
the serum, and NF-κB p65, p38 MAPK, and HMGB-1 were significantly increased in different tissues
of LPS-challenged rats. SBH prevented tissue injury, ameliorated pro-inflammatory cytokines,
and suppressed NF-κB p65, p38 MAPK, and HMGB-1 in rats that had received LPS. In addition,
SBH diminished reactive oxygen species (ROS) production, lipid peroxidation, and oxidative
DNA damage, and enhanced glutathione and Nrf2 in LPS-treated rats.
Conclusion: SBH prevents systemic acute inflammation by suppressing NF-κB, p38 MAPK,
HMGB-1, oxidative stress, and tissue injury in rats. Thus, SBH may represent an effective anti-inflammatory
nutraceutical, pending further mechanistic studies.
