  1. ST111/111 cells with both nuclear and cytoplasmic staining were counted, as well as total cells and dead cells. The effectiveness of the drugs was measured by percentage of cells with nuclear and cytoplasmic staining versus total cells. In untreated cultures, 89% of ST7/7 striatal cells show both nuclear and cytoplasmic immunostaining, while only 1% of ST111/111 striatal cells show this pattern. Entries in the table represent the average values from 5–10 different microcope fields ± standard deviation. Numbers in brackets indicate percentage of dead cells in cases where toxicity was observed.
