The survival rate of H4 cells with heat shock. It was noticed that cell proliferation ability under heat shock at the time point of 30 min(OD_{595 nm}, 0.57 ± 0.03, n = 18) was almost similar with that at 1 h (OD_{595 nm}, 0.57 ± 0.04, n = 18), and a same status was observed at the time point of 2 h(OD_{595 nm}, 0.48 ± 0.03, n = 18) and 3 h (OD_{595 nm}, 0.47 ± 0.03, n = 18) treatment. However, at the time point of 0.5-1 h and 2-3 h treatment, compared with control (OD_{595 nm}, 0.63 ± 0.05, n = 18), cell growth had significantly decreased (p < 0.01) in these two groups. CON: the control cells without heat shock.
