Figure 6: A: TUNEL analysis of rat cerebral cortex in different experimental conditions. Scale bar size 50 μm. Control: untreated sample; Aβ: Aβ-injected cerebral cortex; Aβ+IBU-GSH: Aβ- injected cerebral cortex+IBU-GSH conjugate; C (-): negative control; B: Graphical representation of TUNEL analysis. Apoptotic cells were counted out of total of 100 cells by Leica Qwin Plus 3.5 Software. Percentages values are means ± SD; * Aβ+IBU-GSH conjugate vs Aβ: p < 0.05; C: Transmission electron microscopy analysis of an apoptotic cell. Scale bar size 5 μm
