(1) These different results can be explained by the fact that the unique amalgam investigated by Sarkar and Eyer does not exhibit the same diffusional patterns as does dental amalgam, and that the composition of the gamma 1 in the two amalgams is not the same.
(2) The extensive enzymic dephosphorylation of neurofilaments determined the progressive loss of their capacity to interconnect in vitro into a reticulated network, measured by the formation of highly viscous gels in purified preparations of neurofilaments [Leterrier & Eyer (1987) Biochem.
(3) Furthermore, secondary electron scans of this dental amalgam failed to reveal the intergranular precipitates of Sn-Hg observed by Sarkar and Eyer (1986) in their amalgam.
(4) In a recent study, Sarkar and Eyer (1986) studied an amalgam which was formed using a unique procedure.
