Figure 4From: Anti-HIV-1 activity, protease inhibition and safety profile of extracts prepared from Rhus parviflora Effect of the extracts of R. parviflora on epithelial monolayer integrity. Caco-2 cells were grown in transwell supports until they formed stable monolayer. Plant extracts or vehicle control were added to the apical chamber at t = 0 and resistance was measured at 0.5, 1, 2, 4, 8 and 24 h. As toxicity reference control Triton-X (10%) was added to the indicated apical chambers whereas the test extracts were evaluated at 50 μg/ml. Data shown represent the mean ± SE of two independent experiments performed in duplicates.Back to article page
