Table 4.
Concentration of diazinon (DZ) and hydroxypyrimidine (PYR) in media and slices exposed to 340 nmoles DZ/well. Media only data samples were not incubated with a slice. Media and Slice samples were taken from the same well. The enzyme inhibitor 2-hydroxyquinoline (HQU) was present in the media of the bottom group of data, and was absent in the media of the top group of data. Values represent mean of three replicate samples.
