Figure 4. Climbing ability in the fly-counting apparatus can be measure as both a maximum height able to climb as well as the rate of climbing. (A) Cisplatin treated flies were assessed for the percent of flies able to climb above 4 cm at 2, 4, 6, 8 and 10 sec. (B) We were able to determine the maximum percent of flies able to climb above 4 cm as well as the rate of climbing expressed as the percent of flies able to climb above 4 cm per second. There was a significant decrease in maximum climbing and rate of climbing at 25, 50 and 100 ug/ml cisplatin (p < 0.005). No significant difference observed at 10 ug/ml cisplatin.
