Two separate studies consisting of four and five month exposures to UVA light were conducted, and the data were pooled. Measurements were made with trichloroacetaic acid precipitates. The units are µmol/g wet weight and the results are expressed as means ± s.d. with an n of 11–14. Aged-matched control animals (22 and 23 months old) were housed under normal lighting conditions.
