Results The cell viabilities (means ± SD) of the five 3-MA-treated groups was 100%, 73.13 ± 3.02%, 56.45 ± 2.70%, 34.35 ± 1.65% and 10.14 ± 0.93%, respectively (Figure 7a), while those of the five CHQ-treated groups were 100%, 65.99 ± 3.26%, 48.79 ± 2.51%, 28.04 ± 2.54% and 3.02 ± 0.70%, respectively (Figure 7b).
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
