The sentences
A less robust loss of synaptophysin was seen in the striatum in the aged mice (76.1 ± 7.7% of young mice) which increased with LM11A-31 (91.3 ± 7.2% of young mice) but failed to reach significance due in part to the smaller initial deficit and greater variation.
LM11A-31 significantly reduced the overall loss of cholinergic cell area from −26.6 + 3.8% to −10.1 + 5.5% (MS + VDB) and though similar changes were seen in individual regions, these fell short of significance.
Thus, while there were decreases in cell counts at 18 and 25 months, these did not reach statistical significance.
