Toxicities of ethylene glycol (EG) and 6 ethylene glycol mono alkyl ethers administered orally were studied. Mice were given various doses (62.5, l25, 250, 500, l,000, 2,000 and 4,000 mg/kg body weight) of the compounds daily for 5 days/week, for 5 weeks. High doses of ethylene glycol mono methyl ether (EGM), ethylene glycol mono methyl ether acetate (EGMA), ethylene glycol mono ethyl ether (EGE) and ethylene glycol mono ethyl ether acetate (EGEA) produced marked testicular atrophy and leucopenia. Dose-responce relation was found in these effects. EGM was more effective than EGE, while ethylene glycol mono butyl ether and ethylene glycol mono phenyl ether had but slight effect and EG had no detectable action on testis and leucocytes. Toxic doses being expressed as mg/kg body weight, esterication seemed to weaken the atrophic action of EGM and EGE, but when expressed as mol/kg, significant difference was found neither between EGM and EGMA nor between EGE and EGEA. The mechanism of testicular atrophy induced by low ethylene glycol mono alkyl ethers is likely to be an inhibitory action on cell division.
