Description

The effect of local anoxia (1 hour) upon EP under hypothermic condition (28°C) was observed in 4 albino guiner pigs and the results were compared with those of control animals (37°C, n: 5). The levels of the EP recorded before local anoxia were 84.5mV and 85.5mV at 28°C and 37°C, respectivery. On termination of local anoxia, the EP rapidly increased and reached a certain static level in 30 minutes, i. e. 60.7mV and 49.4mV at 28°C and 37°C, respectivery.<BR>The present results indicate that the reduction of metabolism due to hypothermia protects the damage of the cells in the stria vascularis, resulting in the higher recovery level of the EP after transient local anoxia.
