SENILE PLAQUES Appropriate silver staining and immunohistochemical localisation of b-amyloid show these to be extracellular lesions which in their typical neurite form are roughly spherical in shape (10±50 mm diameter) with a central core of amyloid surrounded by glial processes and a rim of neurites. As long as the writers and readers of a Phase II explanatory study report make no pragmatic claims about its usefulness in routine clinical practice, no harm is done.

A number of culprits have been identified,including activation of kinases,phospholipases leading to the generation of arachidonic acid and free radicals,nitric oxide synthase and also lipases and proteases. Voltage-gated potassium channels nities for the polar peptide bonds to form hydrogen open with a delay relative to voltage-gated sodium bonds with one another in the hydrophobic interior of channels in response to depolarization. There is a balance between the amount of Na filtered and the Loop of Henle amount of Na reabsorbed by the tubules, so the tubules increase the rate of Na reabsorption when GFR is in- creased and decrease the rate of Na reabsorption when GFR is decreased.
