Protective effects of heat shock (HS) from cytotoxicity induced by GM in HK-2 cells. Four groups of HK-2 cells were treated with medium only, HS, GM in 100 µg/mL and GM+HS, respectively, for 24 hr, 48 hr, 72 hr, 96 hr. NAG activity was determined. Values are mean±SD of measurements from separate HK-2 cell cultures. Number of experiments (n)=6. ^*p<0.01 vs. control, ^†p<0.01 vs. GM group.
