Table 1 Mean MTT results of treatments with different concentrations of HESA-A

From: Attenuation of influenza virus infectivity with herbal-marine compound (HESA-A): an in vitro study in MDCK cells

Sample (mg/ml) Mean ± SD
0.8 0.21 ± 0.21٭
0.4 0.26 ± 0.24٭
0.2 0.33 ± 0.24٭
0.1 0.43 ± 0.25٭
0.05 0.51 ± 0.22٭
0.025 0.69 ± 0.20
0.013 0.73 ± 0.18
0.0 1.00 ± 0.00
  1. Values (averages of 4 independent experiments) showed cytotoxicity of different concentrations of HESA-A at different exposure time (24, 48 &72 hr) on MDCK cells (mean ± SD). CC50 and EC50 are determined as 0.05 and 0.025 mg/ml, respectively.: ٭Significantly different from values obtained for HESA-A-treated samples compared to untreated sample (p < 0.05)
