layers of hippocampus

[TA]
four layers formed by cells and cell processes; they are, beginning at the alveus and ventricular surface: the oriens layer [TA] (stratum oriens [TA]), which contains basal dendrites and axon collaterals of the pyramidal cells; the pyramidal layer [TA] (stratum pyramidale [TA]), which contains the somata of the large pyramidal cells of the hippocampus; the radiant layer [TA] (stratum radiatum [TA]), which contains the branching dendrites of the pyramidal cells and recurrent axon collaterals of the pyramidal cells; and the lacunar-molecular layer [TA] (stratum moleculare et substratum lacunosum [TA]), which contains the distal dendrites and some of the incoming axons of the preforant pathway.

In the GLE-ischemia group, SOD1 immunoreactivity in neurons of the stratum pyramidale was continuously maintained after TGCI [Figure 4]d, [Figure 4]f, and [Figure 4]m.
In the vehicle-sham group, BDNF immunoreactivity was observed in neurons of the stratum pyramidale of the CA1 [Figure 4]g.
In the vehicle-ischemia group, BDNF immunoreactivity in neurons of the stratum pyramidale was significantly decreased (about 58% of the vehicle-sham group) 2 days after TGCI and was very low (about 32% of the vehicle-sham group) 5 days after TGCI [Figure 4]i, [Figure 4]k, and [Figure 4]n.
In the 200 mg/kg OJE-sham- and ischemia-groups, CAT immunoreactivity in the stratum pyramidale of the CA1 region was similar to that in the vehicle-sham-group [Table 1] and [Figure 3]b, d and f.
In the vehicle-sham-group, strong Gpx immunoreactivity was detected in the stratum pyramidale of the CA1 region [Figure 3]g.
In the 200 mg/kg OJE-sham-group, Gpx immunoreactivity was very strong in the stratum pyramidale [Table 1] and [Figure 3]h.
