Fig. 3. The dose response of isoflurane delivered for 30 min prior to exposure to cytokines on cell survival in vascular smooth muscle cells (VSM) and human umbilical vein endothelial cells (HUVEC). Results are for 24 and 72 h. # Denotes that isoflurane significantly (P < 0.05) increased cell survival compared to cytokines alone (control). * Denotes that 0.75% significantly (P < 0.05) increased cell survival compared to cytokines alone but less than 1.5%. Data are mean ± SD.
