the purified yeast extract-derived beta-glucans , which contained 92 % glucose and 8 % mannose by gas chromatographic analysis and eluted from a sephacryl s-200 column as a broad peak with a kav of 0.39 and estimated molecular sizes of from 20,000 to 70,000 m.w. , required only 3.5 +/- 0.9 micrograms/ml ( mean +/- sd , n = 6 ) , as compared with 31.5 micrograms/ml of the algal beta-glucan laminarin to achieve 50 % decreases in zymosan ingestion .
