ARCHOPLASM 123 by causing gradual death, morphia undoubtedly hasa profound effect on the cellular cytoplasm, for otheralkaloids, so far as they have been tried, do not causevacuolation of the platelets. On the other hand,we have occasionally seen a vacuolated blood-plateletfrom a specimen of blood which has been mixed forabout twelve hours with a citrated solution (100 percent of suprarenal extract). It has already beenmentioned that extracts of dead tissues lower thecoefficient of diffusion, and in producing vacuolationthey also produce archoplasm in leucocytes (fig. 24).Possibly, as mentioned before, the archoplasm whichis so frequently seen in cancer cells is derived fromthe vacuolation caused by the action of the remainsof dead tissues on the cells.
