    Lesion areas of coronal slices of the brains of female rats visualized by TTC staining after transient (60min) occlusion of the middle cerebral artery. The TTC staining colors viable (well-functioning mitochondria) tissue in red and ischemic tissue lesions in white.

    Areas of ischemic lesions in coronal slices of the brains of female rats determined with the TTC staining method 7days after transient (60min) occlusion of the middle cerebral artery. The lesions were largest at B (6.2±1.7% and B −2mm (5.7±0.9%).

    Gene expression of galanin, galanin receptor1 (GalR1), GalR2 and GalR3 measured by RT-PCR in punch biopsies from locus coeruleus in female rats (n=22) 7days after 60min transient occlusion of the middle cerebral artery. The galanin gene expression in the locus coeruleus was up-regulated by 259% (p<0.01) and GalR1 by 45% (p<0.05) in the ischemic hemisphere as compared to the contra-lateral control side.

    Gene expression of galanin, galanin receptor1 (GalR1), GalR2 and GalR3 measured by RT-PCR in punch biopsies from parietal cortex in female rats (n=22) 7days after 60min transient occlusion of the middle cerebral artery. In cortex, gene expression of GalR1 decreased by 35% (p<0.05) in the ischemic hemisphere as compared to the contra-lateral control side.

    Immunofluorescence micrographs of three different rostro-caudal levels from locus coeruleus of a control female rat (A, C, and E) and a female rat 7days after a 60min transient occlusion of the middle cerebral artery (B, D, F) after incubation with galanin antiserum. Note: strongly fluorescent cell bodies and processes in controls (A, C, and E) versus weak fluorescence in stroke rat (B, D, and F). Bar indicates 100μm.
