A comparative study on the radioprotective potential of the polyphenolic glycoconjugates from medicinal plants of Rosaceae and Asteraceae families versus their aglycones.

Radioprotective potential of the polyphenolic glycoconjugates, isolated from flowers of Sanguisorba officinalis L. (So) and Erigeron canadensis L. (Ec), and from leaves of Fragaria vesca L.

Polyphenolic glycoconjugates from medical plants of Rosaceae/Asteraceae family protect human lymphocytes against γ-radiation-induced damage.

Radioprotective effects of the water-soluble polyphenolic glycoconjugates, isolated from flowers of Sanguisorba officinalis L.(SO) and Erigeron canadensis L.(EC), and from leaves of Fragaria vesca L.

Radioprotectors in radiotherapy - advances in the potential application of phytochemicals.

Radiotherapy, in addition to chemotherapy, is currently the primary method of cancer treatment based on destruction of malignant cells by ionizing radiation. Unfortunately, it also affects normal cells, which is associated with negative consequences for a patient. Radioprotectors are compounds used to prevent/protect the non-tumor cells from the harmful effects of radiation.

Polyphenolic-polysaccharide conjugates from plants of Rosaceae/Asteraceae family as potential radioprotectors.

Polyphenolic-polysaccharide macromolecular, water-soluble glycoconjugates, isolated from the selected medicinal plants of Rosaceae/Asteraceae family: from leaves of Fragaria vesca L., Rubus plicatus Whe. et N.

A moderate protective effect of quercetin against γ-irradiation- and storage-induced oxidative damage in red blood cells for transfusion.

Purpose: To investigate the extent of γ-irradiation-induced oxidative membrane damage and antioxidant activity of quercetin in long-term, cold stored (4°C) acid-citrate-dextrose- preserved human red blood cells (RBC).

Materials And Methods: The extracellular activity of lactate dehydrogenase (LDH) was measured to assess RBC membrane integrity. Lipid peroxidation and reduced glutathione (GSH) levels were quantified by thiobarbituric acid-reactive substances (TBARS) and Ellman's reagent, respectively.

Does quercetin protect human red blood cell membranes against γ-irradiation?

Objectives: Radioprotective potential of quercetin, a powerful free radical scavenger, was investigated in human red blood cells (RBCs) and in isolated RBC membranes exposed to γ-irradiation-induced oxidative stress.

Methods: RBCs and RBC membrane suspensions were irradiated (50 Gy) in the presence of quercetin (2-50 µM). Oxidative damage of the membranes was analysed by protein carbonyl measurement (enzyme-linked immunosorbent assay).
