OBJECTIVES: Bisphenol A Di Glycidyl Ether (BADGE) is the major component in commercial liquid epoxy resins, which are manufactured by co-reacting bisphenol A with epichlorohydrin. The authors investigated the acute toxicity of BADGE. METHODS: BADGE was administered by a gavage to 8 week old SPF Sprague Dawley rats in a single dose of 0 (negative control), 0.37 (Diethylstilbesterol, DES), 1000, 2000, 4000, and 8000 mg/kg/day of BADGE. Each treatment group contained 7 rats. The general status and weight of the rats were observed for 14 days. The rats were anesthetized by ether at 14 days, and the changes in morphology, organ weight, sperm count and motility, and hormone level were measured. RESULTS: All the rats treated with BADGE had diarrhea on the 1st day. The rats administered BADGE at 1000, 2000, and 4000 mg/kg/day showed a soiled perineal region and soft stools with diarrhea until the 3rd day. The 8000 mg/kg/day BADGE rats had diarrhea for two days followed by emaciation, soiled fur, a soiled perineal region, staining around the mouth and were moribund for three to eight days. No weight gain was observed after the 1st day in the 2000, 4000, and 8000 mg/kg/day BADGE rats and after the 7th day in all the treatment groups compared with the control groups. Some treatment groups were observed to have a decrease in the weight of the heart (BADGE 1000, 2000 and 4000 mg/kg/day), liver (BADGE 1000, 2000, 4000 and 8000 mg/kg/day) and prostate (BADGE 4000 mg/kg/day) compared with control group. The weight of the liver was significantly lower in all treatment groups compared with the control group. The relative weight of the liver (BADGE 1000 and 4000 mg/kg/day) was significant lower than the control. No pathological changes were observed in the brain, liver, thyroid, heart, spleen, kidney, lung and prostate. The number of spermatid in the seminiferous tubule in the testes was lower in all treatment groups than the control. The sperm motility tended to decrease with increasing concentration but the sperm count was similar in all treatment groups. The plasma Estrogen and testosterone level were similar in the control and treatment groups. CONCLUSIONS: These results suggest that BADGE induces general, hepatic and reproductive toxicity at 1000 mg/kg/day.
