Figure 4. The detection of cell death induced by hyperbaric stress and 5 µM of glutamate. Hyperbaric stress and 5 µM of glutamate did not induce apoptosis and necrosis, but both hyperbaric stress and 5 µM of glutamate significantly increased apoptotic cell death. Necrosis was constant and independent of each stress. Data indicates mean±SD, *; p<0.05 from Steel’s test. n=7–8.
