Figure 3.

Effect of morphine dependency on ischemia-induced neuronal cell loss. Representative pictures of sham (A), IR (B), MD+IR (C), Nal+ IR (D), MD+ Nal+ IR (E), L-NAME+IR (F) and MD+L-NAME+IR (G) 72 hr after ischemia (400×). Black arrows are indicating intact cells and red arrows indicating necrotic cells. Data has been expressed as the number of counted live hippocampal CA1 neurons (Mean± SEM). Statistical analysis for cell density was done using one-way ANOVA followed by Tucky test (Mean± SEM) (H). ## P<0.01 and ### P<0.001 vs. IR group and **P<0.01 and *** P<0.001 vs. MD+IR group
