Investigation on the Molecular Mechanism of Photorejuvenation in Photodynamic Therapy
… clinical studies reported that the PDT has photorejuvenation effects on the aged skin. In the previous report, which is examined direct effect of PDT on fibroblast (FB), PDT induced increase of matrix metalloproteinase (MMP)-3 and collagen type Iα through prolonged activation of …

Histological Changes in Photorejuvenation Induced by 5-Aminolevulinic Acid Photodynamic Therapy in a Photoaged Mouse Model
… mouse skin specimens and in the specimens after photorejuvenation induced by 5-aminolevulinic acid (ALA)-PDT. Furthermore, I investigated transmission electron microscopic (TEM) studies to observe the differences among normal, photoaged, and post-ALA-PDT biopsy specimens. Materials and Methods: …

Investigation on the Intracellular Sognal Transduction Mechanism of Human Dermal Fibroblasts of Photorejuvenation in Photodynamic Therapy
… no studies on the intracellular mechanism of photorejuvenation following PDT. The purpose of this study was to investigate the effects of PDT on the signal transduction mechanism in human dermal fibroblast and the role of reactive oxygen species (ROS) in vitro. Normal human fibroblasts were …

Photorejuvenation Induced by 5-Aminolevulinic Acid Photodynamic Therapy in the Patients with Actinic Keratosis: A Histological Analysis
… induced histological changes suggesting photorejuvenation. Materials and Methods: Fourteen patients with one to three actinic keratosis on the face were treated twice with ALA-PDT using a 1200W metal halogen lamp at one month intervals. Skin biopsy before and one month after the PDT was …
