Yield of formation of 8-oxodGuo and thymine cyclobutane dimer (T<>T) within human skin exposed to UVA radiation

Donors	8-oxodGuo	T<>T	Ratio T<>T/8-oxodGuo
F	0.0085 ± 0.0064	0.057 ± 0.007	6.7
G	0.0080 ± 0.0030	0.077 ± 0.009	9.6
H	0.0087 ± 0.0039	0.061 ± 0.004	7.0
I	0.0066 ± 0.0024	0.050 ± 0.005	7.6
J	0.0081 ± 0.0040	0.040 ± 0.003	5.0
K	0.0023 ± 0.0036	0.112 ± 0.004	48.8
Mean	0.0071 ± 0.0025	0.066 ± 0.025	9.4

The results (expressed in lesions per 10⁶ normal bases per Joules per centimeter squared) represent the slope ± SE of the linear regression for 8-oxodGuo or T<>T with respect to the applied UV dose for each donor. The mean is average ± SD.
