Sequential changes in brain length in rats 60 days after 35 mg/kg MNU treatment.

| Group | Total brain length | Cerebral width | Cerebellar length | Cerebellar width |
| Basal dieta + saline injection | 18981 | 14614 | 4986 | 11539 |
| Basal diet + MNU injection | 17669d | 13999 | 2534d | 10804c |
| AA dietb + saline injection | 19232 | 14756 | 5367 | 12030 |
| AA diet + MNU injection | 17758d | 13882 | 2619d | 11499 |
aThe basal diet contained 0.008% AA; bthe arachidonic acid (AA) diet contained 2.0% AA. Mean values were significantly different between saline and N-methyl-N-nitrosourea (MNU) treatment in each diet group (cP<0.05 and dP<0.01). By contrast, mean values were not significantly different between the basal and AA diet groups for each treatment.
