Figure Lengend Snippet: Representative low-magnification photomicrographs of mice CA1 following different injection regimes for the proteins, i.e., fibrinogen and CFAH: A Vehicle, B Fib 2.5, and C Fib 5. C1 Arrows indicate chromatolysis, D CFAH 2.5. E CFAH 5. E ****(asterisks) represent necroptotic cells. Histograms showing the morphometric index of CA1 neurons. F Histograms show significant increase in the area of the neuronal nucleus of Fib 5 µg, (Fib 5 vs. vehicle ** p = 0.0026). G A significant increase in the cytoplasmic area of the neurons Fib 2.5 vs. vehicle ** p = 0.0090, Fib 5 vs. vehicle * p = 0.0182. H Histogram showing unaltered volume of the CA1. I Vehicle- J Fib 2.5-, K Fib 5-, and L CFAH 2.5-injected animals showed patches of hypertrophied cells. M Arrows denote the ‘necroptotic spots’ in the subiculum of CFAH 5 study group, indicating degenerative changes. N The histograms confirm nuclear enlargement of the neuronal nucleus of Fib 2.5 µg, Fib 5 µg, CFAH 5 µg, Fib 2.5 vs. vehicle * p = 0.0461, Fib 5 vs. vehicle ** p = 0.0012, CFAH 5 vs. vehicle * p = 0.0376). O Histograms showing significant increase in cytoplasmic area in Fib 2.5 and Fib 5 study groups, Fib 2.5 vs. vehicle * p = 0.0114, Fib 5 vs. vehicle ** p = 0.0063) both suggesting cellular hypertrophy. P Histogram showing unaltered volume. Scale bar = 10 µm
