Percentage inhibition of monkey kidney cells lines maintained in culture for four days before exposure to Euphorbia hirta extracts for two days 2 . 2. Percentage inhibition of potassium cyanide (KCN) at 103 μg/ml = 52.8%; the optical density (OD) values for 1% DMSO (solvent control) = 0.109, cells cultured in plain culture medium = 0.149, and for heat killed cells = −0.037 (negative figures imply promotion of cell maintenance).
