Fig. 1. Lactate dehydrogenase (LDH) release ( A ) and 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide (MTT) conversion ( B ) expressed as percent of control in mouse HL-1 cells ( solid bars ) and neonatal rat ventricular myocytes ( hatched bars ) under control (CON) conditions, after exposure to hypoxia (HYPOX), and after pretreatment with isoflurane in the presence (ISO + HYPOX) or absence (ISO) of hypoxia. * Significantly ( P < 0.05) different from CON; † significantly ( P < 0.05) different from HYPOX, n = 5.
