a
LC50, median lethal concentration; *, median lethal times (LT50) were calculated at 8,890 PIB/cm2; †, LT50 values were calculated at 5 × 106 PIB/cm2.
b
The LT50 value was not calculable (NC) because of only 8.0% mortality at a dose of 8,890 PIB/cm2.
c
The LT50 value was not calculable (NC) because of no mortality at a dose of 5 × 106 PIB/cm2.
