- Soft tissue examinations: Yes: [1/3 per litter ]
- Skeletal examinations: Yes: [2/3 per litter ] - Statistics:
- All statistical analyses compared the treatment groups with the control group, with the level of significance at p<0.05. Male to female foetal sex ratio and number of litters with anomalies were compared using the Chi-square test criterion with Yates correction for 2 x 2 contingency tables and/or Fisher's exact probability test as described by Siegel to Judge significance of differences. The proportion of late resorbed foetuses and postimplantation losses were compared by the Mann-Whitney U-test as described by Siegel and Weil to judge significance of differences. Mean number of corpora lutes, total implantations and viable foetuses were compared by analysis of variance (one-way classification), Bartlett's test for homogeneity of variances and the appropriate t-test (for equal or unequal variances) as described by Steel and Torrie using Dunnett's multiple comparison table to judge significance of differences. Fetal body weights were compared by analysis of variance (hierarchal classification) and t-test as described by Steel and Torri using Dunnett's multiple comparison tables to judge significance of differences.
Results and discussion
Results: maternal animals
Maternal developmental toxicity
- Details on maternal toxic effects:
- Maternal toxic effects:no effects
Details on maternal toxic effects:
Respiratory involvement and red nasal discharge were observed in all dosage groups. The incidence of these was higher in the treated groups, though not in a dose-related pattern. No treatment-related deaths (one rat in each dosage group died during the first part of treatment; the cause of death was not determined) nor abnormal behaviour was observed in any of the maleic anhydride treated groups. Mean body weight gain was reduced in the 30 mg/kg/day dosage group for the first three days of treatment. There was a slight mean body weight loss in the 90 and 140 mg/kg/day dosage groups for the first three days of treatment. These reductions in weight gains resulted in reduced mean body weight gains over the entire treatment period in all treatment groups compared to the control (however, mean weight of all groups was within 5% of control on days 15 and 20. No biologically meaningful differences in the mean number of viable foetuses, implantations, post implantation losses, corpora lutea, or in the male to female sex ratio between any of the maleic anhydride treated groups and the control group. The general appearance and behaviour of rats were not affected by treatment.

- Embryotoxic / teratogenic effects:no effects
Details on embryotoxic / teratogenic effects:
Mean foetal body weights were lower in the treatment groups than in the control group. This was not considered compound related due to the unusually high mean foetal body weight in this concurrent control group (mean: 4 g). External evaluation, internal examination, and skeletal observations of foetuses from all three treatment groups showed no anomalies in foetal development which could be attributed to maleic anhydride (slight increase in foetal malformations in the 30 (2/23 litters) and 140 mg/kg/day dosage group (3/21 litters) when compared to the control group (1/23 litters) is considered due to random occurrence due to the variety of abnormalities observed).

Applicant's summary and conclusion
- Conclusions:
- It is concluded that the treatment with maleic anhydride up to 140 mg/kg/day did not produce a teratogenic response in CD rats.
- Executive summary:
It is concluded that the treatment with maleic anhydride up to 140 mg/kg/day did not produce a teratogenic response in CD rats.
