| Abstract: | Rather high species sensitivity to carminomycin was found in the experiment with albino mice, rats, guinea pigs, rabbits and dogs. The highest difference in the antibiotic toxicity for various species of the laboratory animals was shown on oral administration of the drug which was due to the differences in the antibiotic absorption from the gastro-intestinal tract. On single oral administration to the dogs in toxic or lethal doses the antibiotic suppressed the blood formation up to aplasia of the bone marrow. The equitoxic doses of carminomycin on its single oral and intravenous administration differed approximately by 3 times. Carminomycin had no effect on the smooth muscles of the isolated rabbit ear vessels and cat intestine in situ. The antibiotic had an irritating effect on the rabbit eye mucosa. Carminomycin had no skin-irritating effect. |
