7613. Brougham, F. J., [Preyss, W. von]. April 6. Albumens and albuminoids; ferments; cholesterins; glycerides; phosphates, ethereal; uric acid &c. -High-frequency alternating-currents are used to effect heating in the production of organic preparations, either by passing the current between electrodes applied to the substance to be treated, or inductively, or by capacity effect ; the current may be sent by several paths through a place to be specially warmed, so that a greater effect is obtained there. Any organ in a living body may thus be warmed, and undesired reactions such as oxidation by the oxygen in the air in the case of lecithins or cholesterins, or coagulating or splitting processes, in the case of a solution containing protein, can be avoided. By confining the heat to different layers of a liquid, solutions of precipitates can be effected, or fractional precipitations can be made. The method of heating can be used to cause frictional coagulation of sensitive albuminoid bodies, and for rendering catalytic bodies such as enzymes more effective.
