1 Humic acid had significant photosensitization on tetramethrin, and itsphotosensitization increased rapidly as the humic acid concentration increased.

2 HPD photosensitization may also destroy the arrangement and conformation of target molecules, leading to the disorder and damage of the cell membrane structure.

3 CONCLUSION: Photosensitization is quite capable of embolizing the rather large veins, therefore, the photosensitive treatment for venae impotence show certain feasibility.

4 It may be used in biological analysis, medicament design and development, solar cell, optical disc photosensitization and other fields.

5 In this paper, ESR, spin trapping and spin counteraction are used to study the photosensitization of hypocrellin A(HA) and cercosporin(CP) in homogeneous and heterogeneous systems separately.

6 Although described in several species, it is most important as a cause of photosensitivity in cattle (see Photosensitization: Introduction).

7 It was also found that acetone was an effective aid to improve photosensitivity of tfiadimefon to photolysis and its photosensitization rate was found distinctly related to its concentration.

8 In addition, the obtained kinetic constants are valuable to understand the suitable region for the application of these photosensitization initiation systems.

9 The HPD nitroxide free radical was first synthesized and used to study the influence of ginsenoside on the photosensitization of HPD.
