Title: Inhibition of Radioactive Depletion of Hemocytes and Antitumor Effects of Flavonoid
Abstract: Natural products are able to inhibit radiation effects and exert an antitumor effect with fewer adverse reactions; however, their antitumor effects are less than those of widely-used synthetic drugs. Flavonoid is a natural material that has attracting attention, and we extracted this material with alcohol and investigated the effect of continuous flavonoid administration on radioactivity-induced reduction of hemocytes, in addition to the antioxidant and antitum or effects of flavonoid. Following a 1-week adjustment period, flavonoid was administered intraperitoneally to male ICR mice at a dose of 100 mg/kg every other day for 2 weeks.
