Effects of Tualang honey on hydrogen peroxide and HCEP cell resistance to oxidative stress.

<p>(A) <i>In vitro</i> inhibitory effects of Tualang honey at 0.04, 0.4, and 4% (v/v) against 5, 10, 20, 30, and 40 µM H₂O₂. (B) HCEP viability in response to H₂O₂ induction at 0, 10, 20, 50, 100 and 200 µM after 24 hours using AlamarBlue assay. (C) Flow cytometric analysis showed the total number of PI-stained dead cells in Tualang honey treated HCEP cells in response to exposure to 50 µM H₂O₂ after 24 h (**<i>p</i><0.01 compared to untreated control). Abbreviation: PI, propidium iodide.
