With most cells the main changes fall upon their metabolism. These nutritive changes are most pronounced in the cells of lowest vitality. As a rule, pathologic formations possess less resistance than normal tissue, so that one of the most conspicuous phenomena of the general salt action is the breaking-down of pathologic formations, no matter what their origin, and whether they are chemic or anatomic. Other specialized tissue also respond by their proper functions: Abstraction of water from a nerve or muscle causes contraction; the unfertilized eggs of certain marine animals undergo parthenogenetic development, etc. (J. Loeb, 1899, 1901). If a very strong salt solution is injected directly into the circulation, the main symptoms will arise from the central nervous system. They consist in stimulation, with subsequent paralysis, being similar to the effects of asphyxia. 3. Effects on the Blood and Lymph.--Fate of Salt Solutions Within the Body.--In what concentration and by whatever channels salts are introduced into the body, they will tend to increase the quantity of blood, or rather of plasma; and to render it more watery and less viscid; in other words, to produce hydremic plethora. If isotonic or hypoisotonic solutions are introduced, they will dilute the blood by their own fluid; if hypertonic solutions are injected, the blood will draw fluid from the tissues until it has resumed its original concentration. The result will be hydremia in either case. If anisotonic solutions are introduced, they will temporarily alter the molecular concentration of the plasma. However, the blood possesses a remarkable poivcr of resumin...
