Osteoradionecrosis and PENTOCLO Protocol: Retrospective Study

2019-09-26 05:42:42 | BioPortfolio


osteoradionecrosis (ORN) affects up to 30% of irradiated patients and can occur up to several decades after stopping treatment. Differents therapeutics exist but there is no consensus concerning the management of the maxillary ORN. The understanding of new pathological mechanisms opens the way to new therapeutic perspectives.

Medical and Biotech [MESH] Definitions

A natural tocopherol with less antioxidant activity than alpha-tocopherol. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. As in GAMMA-TOCOPHEROL, it also has three methyl groups on the 6-chromanol nucleus but at different sites.

A natural tocopherol with less antioxidant activity than ALPHA-TOCOPHEROL. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. As in BETA-TOCOPHEROL, it also has three methyl groups on the 6-chromanol nucleus but at different sites.

A natural tocopherol and one of the most potent antioxidant tocopherols. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. It has four methyl groups on the 6-chromanol nucleus. The natural d form of alpha-tocopherol is more active than its synthetic dl-alpha-tocopherol racemic mixture.

A METHYLXANTHINE derivative that inhibits phosphodiesterase and affects blood rheology. It improves blood flow by increasing erythrocyte and leukocyte flexibility. It also inhibits platelet aggregation. Pentoxifylline modulates immunologic activity by stimulating cytokine production.

Necrosis of bone following radiation injury.
