[Twenty-eight-day repeated dose toxicity test of pentaerythritol in F344 rats].
A twenty-eight-day repeated dose toxicity test of pentaerythritol at dose levels of 1000 or 0 mg/kg/day was carried out in male and female F344 rats. Thirteen animals of each sex were divided into 2 groups with 7 rats receiving pentaerythritol treatment and 6 rats served saline as control. All groups received an i.g. administration daily for 28 days. As to serum biochemical and hematological examinations, there were no serious differences between the pentaerythritol-treated rats and the control rats. On histopathological examination, no specific changes were observed in the pentaerythritol-treated rats. Based on these results, the no-observed-effect level of pentaerythritol can be concluded to be more than 1000 mg/kg/day.
