After complex use of Lecithine and local dosed vacuum of medium degree for treatment of experimental parodontitis we revealed that in parodontal tissues in group of elder rats the content of Malonic dialdehide has been decreased. However, the activity of superoxiddismutase, glutathionperoxidase, glutathionreductase was increased, the contents of Ca and P became considerably increased. Due to the described above treatment the resorption of alveolar process was also decreased and parodontoprotection was more significant in group of elder rats in comparison with experimental animals of “younger age”.
