TY - JOUR AU - Gurd, Fraser B. AB - VARIATIONS IN THE COMPLEMENT CONTENT OF SERUM AND PLASMA.*t FRASER B. GURD.~ (From the Laboratory of Experimental Medicine, McGill University, Montreal.) That doubt as to the presence or absence of complement in the circulating plasma should still exist after several years of obser­ vation and repeated experiment, seems, at first sight, somewhat extraordinary. That there is a difference of opinion on the sub­ ject is evident from the diverse statements which, in turn, are based on the observation of experiment, published by different authors. Gengou,' over 10 years ago, satisfied at least himself that plasma does not contain a complementary body capable of reactivating specific sera in vitro. Since this time a moderate number of contributions have appeared relative to the subject; a relatively small proportion of these authors substantiating Gengou's observations, the majority stating their belief in the erroneousness of his conclusions. The most recent article upon this subject is that by Addis/ who, basing his opinions on the results of his experiments upon cock's plasma and serum, states unqualifiedly that complement is present in substantially equal quantities in both plasma and fresh serum. He refers briefly to the work of Hermann, Domery, Sweet, Hewlett, Lourt, Schwartz, and TI - Variations in the Complement Content of Serum and Plasma† JF - The Journal of Infectious Diseases DO - 10.1093/infdis/11.2.225 DA - 1912-09-01 UR - https://www.deepdyve.com/lp/oxford-university-press/variations-in-the-complement-content-of-serum-and-plasma-3Q1vJWBu0B SP - 225 EP - 234 VL - 11 IS - 2 DP - DeepDyve ER -
