(16) The rate of accumulation was highest late in infection and only the slower migrating form incorporates significant amounts of glucosamine.
(17) Initiation of the alternative pathway by the cryptococcal capsule is characterized by a lag in C3 accumulation and the appearance of a limited number of focal initiation sites which resemble those observed when the alternative pathway is activated by zymosan and nonencapsulated cryptococci.
(18) Accumulating evidence indicates that for most tumors, the switch to the angiogenic phenotype depends upon the outcome of a balance between angiogenic stimulators and angiogenic inhibitors, both of which may be produced by tumor cells and perhaps by certain host cells.
(19) The aim of our experiments was to investigate firstly whether during an acute inflammatory process platelets accumulate in the inflamed area and secondly whether the inflammation has an effect on the properties of the platelets.
(20) The accumulated evidence would strongly favor an affirmative answer.
