Figure 1From: In vitro inhibition of human leukemia THP-1 cells by Origanum syriacum L. and Thymus vulgaris L. extractsReduction of THP-1 cells and PBMCs viability in response to increasing extracts and DMSO concentrations. Dose response curves of THP-1 cells (A) and PBMCs (B) were constructed after 48 h treatment with O. syriacum and T. vulgaris extracts and DMSO. The cells viability was assayed by the colorimetric MTT based assay. The X-axis is in logarithmic scale.Back to article page
