Table 2. Histopathological scoring of affected neurons numbers and hippocampus acute damage neurons .

Score	Numbers of affected neurons	Score of cerebral tissue acute damage
0	Normal	Normal
1	Few affected neurons	Normal nucleus, scalloping at the cytoplasmic boarder
2	Many affected neurons	Nuclear shrinking, smeared nuclear-cytoplasmic detail
3	All neurons affected	Shrunken neuron with no nuclear-cytoplasmic detail
