Abstract

Purpose Antrodia camphorata (AC), a highly valued polypore mushroom native only to Taiwan, has been traditionally used as a medicine for the treatment of food and drug intoxication, diarrhea, abdominal pain, hypertension, skin itching, and cancer. In this study, both of solid-state-cultured AC (S-AC) and wood-cultured AC (W-AC) were evaluated the anti-inflammatory effects on hyperoxia-induced lung injury in NF-κB-luciferase+/+transgenic mice.

Methods The homozygous transgenic mice (NF-κB-luciferase +/+) were randomly assigned to four groups for treatment (n = 6) including Normoxia/DMSO group, Hyperoxia/DMSO group, Hyperoxia/S-AC group, and Hyperoxia/W-AC group. After 72 h of hyperoxia, we examined the bioluminescence images, reactive oxygen species (ROS), the mRNA and protein expression levels of inflammation factors, and histopathological analyses of the lung tissues.

Conclusions These results demonstrated that methanolic extracts both of S-AC and W-AC have excellent anti-inflammatory activities and thus have great potential as a source for natural health products.

Results Hyperoxia-induced lung injury significantly increased the generation of ROS, the mRNA levels of IL-6, TNF-α, IL-1β and IL-8, and the protein expression levels of IKKα/β, iNOS and IL-6. Pulmonary edema and alveolar infiltration of neutrophils was also observed in the hyperoxia-induced lung tissue. However, treatment with either S-AC or W-AC obviously decreased hyperoxia-induced generation of ROS and the expression of IL-6, TNF-α, IL-1β, IL-8, IKKα/β and iNOS compared to hyperoxia treatment alone. Lung histopathology also showed that treatment with either S-AC or W-AC significantly reduced neutrophil infiltration and lung edema compared to treatment with hyperoxia treated alone. To find out their major compounds, eburicoic acid and dehydroeburicoic acid were both isolated and identified from S-AC and W-AC by using HPLC, MS, and NMR spectrometry.
