Photodynamic impact on the epiphyseal plates.

This study was carried out to prove the possibility of inhibition of long bones epiphyseal plates activity with photodynamic impact. Comparative analysis of the Chlorin E6 accumulation with transcutaneous and intraperitoneal administration mode, carried out on 175 laboratory mice showed the drug accumulates selectively in the epiphyseal plates of long bones, regardless of the mode of administration. 15 mice (males and females) at the age of active grownig were subjected to the single laser radiation impact on the knee joints area: 5 ones with transcutaneous Chlorine E6 administration, another 5 ones with intraperitoneal administration and the rest 5 without the drug.
