The data documented in this study show that tonsillectomy with bipolar scissors might represent a surgical option to reduce surgical time in a larger patient group. Postoperative pain and the incidence of postoperative bleeding did not show any statistical difference between the two surgical techniques.
IF blood-serum be saturated completely with sulphate of magnesia, the whole of the serum-globulin which it contains is precipitated, and may be separated by filtration1. The only proteid that is known to be present in any appreciable amount in the clear filtrate is serum-albumin. This substance it is well known coagulates when in solution at temperatures varying between 600 0. and 750 C., the coagulation at the lower temperatures (600 or thereabouts) being incomplete, and sufficient only to render the fluid opalescent. The variation is largely due moreover to varying reaction of the fluid, the more completely neutral, the lower the temperature of heat-coagulation; the more alkaline, the higher. It is to be expected therefore that the serum-albumin in the clear filtrate above mentioned will, if gradually heated, begin to coagulate at a temperature not lower than about 600 C., the complete coagulation of the albumin not occurring until a higher temperature is reached.It is stated however by Fredericq2, who seems first to have performed the experiment in the manner above indicated, that the serumalbumin (or serine) begins under the circumstances in question to become precipitated at a far lower temperature than would have been anticipated. Fredericq found that in serum saturated with magnesic sulphate and filtered, a considerable deposit frequently occurred at or a little above 400 C., and that as the temperature was gradually raised, fresh deposits occurred, until by the time 500 0. was reached, nearly the whole of the serine had been precipitated3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
