Opuntia ficus-indica (OFI), or Pricky Pear Cactus, is effective in cough, fever, pain and anti-inflammatory action, and asthma. This study aims to investigate the effect of OFI stem extract on the respiratory system of animal mod els induced by ovalbumin (OVA) and fine dust (PM10) and to analyze the indicator substances of OFI stem extract.
In the OFI stem 50% ethanol extract (OFI-50E) administration group, the number of immune cells and inflammatory cytokines in the lungs and BAL decreased to a similar level to the positive control group administered with dexa methasone. In addition, OVA-specific IgE and airway hyper-reactivity (AHR) were significantly reduced. Also, the deposition of PM10 observed through staining of lung tissue was clearly reduced in the OFI-50E 200 mg/kg admin istration group. The anti-inflammatory mechanism in the lung was found to obstruct the production of inflammatory cytokines by impeding the NF-kB and MAPK pathways through the inhibition of IRAK-1 active cells. The main component of OFI stem 50% ethanol extract was identified to be narcissin. According to the study results, OFI is expected to be a respiratory health functional food.
