Hydroquinone Mutagenicity Assay
Description
This data set gives the number of micronuclei per animal and 2000 scored cells for six different groups of differently treated male mice: The negative control (C-), four doses (30, 50, 75, 100 mg hydroquinone / kg) of hydroquinone and an active control (C+) (with 25 mg/kg cyclophosphamide).
Usage
data(hydroquinone)
Format
A data frame with 31 observations on the following 2 variables:
- group
A factor with levels "C-", "30 mg/kg", "50 mg/kg", "75 mg/kg", "100 mg/kg" and "C+" specifying the groups.
- micronuclei
A numeric vector, giving the counts of micronuclei per animal and 2000 scored cells after 24h.
