[Pathomorphological picture of the testes of mice administered antitumor antibiotics and their comparative evaluation].

A single administration of the LD50 of bruneomycin, carminomycin, rubomycin or olivomycin and the use of the antibiotics for 10 days in a dose 2 times higher than the therapeutic one and amounting to 10 per cent of the LD50 induced dystrophic and destructive changes in the sexual glands of mice. The changes in the testis were more pronounced after the single use of the antibiotics. Recovery processes were observed in the testis beginning from the middle of the third week after the use of carminomycin and rubomycin and from the end of the second week after the use of olivomycin. Bruneomycin was an exception: the pronounced destructive changes in the sexual glands after its single or repeated use persisted within the observation period.
