PRIMARY outcome

Timeframe: untreated and LaserGenesis treated, three months after treatment, 24 hours after 350 J/m2 of UVB

Population: untreated and laser treated biopsies were taken from each subject

Number of double positive cells per 1000 total basal layer keratinocytes

Outcome measures

Measure
LaserGenesis Treatment
n=11 Participants
1064 nm laser at a fluence of 13-16 J/cm2 and a pulse width of 0.3 ms and a 5 mm spot size
Difference in Basal Layer Keratinocytes Positive for Both Ki67 and Thymine Dimers
Untreated skin
21.5 positive cells/1000 basal layer cells
Standard Deviation 16.3
Difference in Basal Layer Keratinocytes Positive for Both Ki67 and Thymine Dimers
Laser-treated skin
14.7 positive cells/1000 basal layer cells
Standard Deviation 13.4

SECONDARY outcome

Timeframe: untreated and LaserGenesis treated, three months after treatment

Population: untreated and laser treated biopsies were taken from each subject

IGF-1 mRNA per 100,000 beta-2 microglobulin mRNA. Beta-2 microglobulin mRNA was used as a reference gene for this assessment and that the data represent number of copies IGF-1/100,000 copies b2-microglobulin.
