[Combined effect of quercetin and indralin (B-190) in alleviating carboplatin hematologic toxicity]

In experiment conducted on male mice of C57B1/6 line quercetin (80-100 mg/kg injected 60 minutes before carboplatin) or an emergency radioprotector indralin B-190 (50-100 mg/kg injected 5 minutes after carboplatin) decreased the mortality of animals from toxic carboplatin dose of 100 mg/kg from 40% to 10-11% (p < 0.05). In mice receiving both quercetin and B-190 the reduction of carboplatin toxicity evaluated by blood WBC level was even more prominent (p < 0.05). The results were confirmed in rat experiment. In animals receiving both quercetin and B-190 with 50 mg/kg of carboplatin the WBC level was higher (p < 0.05). Quercetin alone had no effect on hematologic toxicity in those settings. Besides, quercetin and B-190 didn't have any effect on RBC level changes.
