Suppression of 7,12-dimethylbenz[a]anthracene-induced chromosome aberrations in rat bone marrow cells after treatment with Sudan III and related azo dyes. 1982

Y Ito, and S Maeda, and T Fujihara, and N Ueda, and T Sugiyama

Noninbred Long-Evans rats fed Sudan III at 24 hours before they were given an injection of 7,12-dimethylbenz[a]anthracene (DMBA) displayed prominently suppressed DMBA-induced chromosome aberrations (CA) in their bone marrow cells. Rats fed Sudan III simultaneously with the DMBA injection showed no suppressed CA effect. The suppressive effect of Sudan III on DMBA-induced CA paralleled the dose rate of Sudan III when given in the range between 1 and 10 mg Sudan III/kg body weight; higher doses produced no additional suppression. The capacity of various Sudan III-related chemicals to prevent DMBA-induced CA paralleled their capacity to prevent DMBA-induced adrenal apoplexy and mammary cancer. Among the azo dyes investigated, Sudan III was most efficient in protecting against DMBA-induced CA. Polychlorinated biphenyl and phenobarbital, inducers of drug-metabolizing enzymes, also suppressed DMBA-induced CA.

D010634	Phenobarbital	A barbituric acid derivative that acts as a nonselective central nervous system depressant. It potentiates GAMMA-AMINOBUTYRIC ACID action on GABA-A RECEPTORS, and modulates chloride currents through receptor channels. It also inhibits glutamate induced depolarizations.

D011078	Polychlorinated Biphenyls	Industrial products consisting of a mixture of chlorinated biphenyl congeners and isomers. These compounds are highly lipophilic and tend to accumulate in fat stores of animals. Many of these compounds are considered toxic and potential environmental pollutants.

D001853	Bone Marrow	The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

D000311	Adrenal Glands	A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
