Hypothesis
The study aims to determine the kinetics of porphyrin generation in tissues after topical application of ALA delivered in different vehicles.
Conclusion
The formulation of ALA vehicle significantly influences the penetration through the skin and the accumulation of porphyrins in tissues.
Supporting Evidence
- Maximal accumulation of porphyrins was found in tumors 3 hours after ALA application.
- Different kinetic patterns were observed in normal and tumor-invaded skin tissues.
- ALA lotion induced higher accumulation of tumor porphyrins than cream.
- Lotion applied on normal skin was the most efficient in inducing total body porphyrins.
Takeaway
This study looks at how a special cream or lotion helps a medicine called ALA work better in treating skin tumors by measuring how much of it gets into the body.
Methodology
The study involved applying ALA in different vehicles on the skin of mice and measuring porphyrin accumulation in various tissues.
Participant Demographics
Mice were used in the study.
