A decrease in carboplatinum hemotoxicity was detected in experiments on C57B1 mice treated with the drug in combination with indralin (urgent radioprotector). Carboplatinum in a dose of 125 mg/kg, injected intraperitoneally, caused 80-100% death; the median term of death was 6 days (3-17). Single oral dose of indralin (100 mg/kg) during the 1st min or 15 min after carboplatinum injection (125 mg/kg) increased animal survival by 40.0-46.7% by day 20 of the experiment primarily during the period of manifest hemotoxicity (days 7-17), indralin injected 1, 2, or 4 h after carboplatinum exhibited no chemoprotective effect.

Daily treatment of outbred albino mice with gammafos in radioprotective doses of 300 and 500 mg/kg for 4 days produced a cumulative toxic effect. This effect was not observed after decreasing the dose of gammafos to 100 mg/kg. Repeated peroral administration of melatonin and ascorbic acid in a dose of 200 mg/kg 30 min before treatment with gammafos reduced its cumulative toxic effect. Succinic acid in a dose of 100 mg/kg was ineffective under these conditions. The cumulative death time for 50% animals receiving gammafos alone or in combination with melatonin, ascorbic acid, and succinic acid was 3.08, 4.29, 4.06, and 2.97 days, respectively.
