(A) Scheme of l-NAME or d-NAME infusion and
BrdUrd administration. (a and b) Projection diagrams of the
relationship of the infusion point into the LV of the rat brain showing
anatomy including the SVZ, RMS, LV, OB, and DG. (c) The protocol for
administration of BrdUrd and l- or d-NAME in relation to
the time for surgery (S), infusion of drugs, and perfusion (P). (B)
Changes in the numbers of BrdUrd+ nuclei after persistent NOS
inhibition. Absolute counts of BrdUrd+ nuclei of different regions
from serially sampled sagittal sections of l-NAME-infused animals
show increases in all areas examined when compared with
d-NAME-treated animals. The “total” column represents
the sum of all the regions examined. The Mann–Whitney test shows that
the differences in all tested regions were significant (P < 0.05;
see Table 1). DG here refers to
the S-GCL and GCL.
