해수로부터 분리 확인한 비브리오균에서 생산하는 단백 다당체의 항종양 활성에 대하여 조사하였다. 비브리오균을 0.5%-peptone와 0.5% yeast extract가 함유된 해수를 기질로 배양하여 단백 다당체를 얻었다. 단백다당체의 단당류의 함량은 xylose, mannose, galactose, glucose 및 fructose의 순서이고, 주요 아미노산 glutamic acid, serine 및 aspartic acid였다. 단백 다당체의 항종양 활성을 Sarcoma-180에 대하여 0.5mg/kg/day 및 5mg/kg/day을 쥐에 주사했던 바 20.9% 및 43.9%의 억제 효과가 있었다.
The antitumor activity of protein-polysaccharide produced by a strain, Vibrio anguilfarum, No. 17 isolated from sea water was investigated. The extracellular protein,polysaccharide used in this experiment was obtained through the cultivation of Vibrio anguillarum No. 17 at $25^{circ}C$ for 5-7 days in the sea water medium containing 0.5% peptone and 0.1% yeast extract. The compositional monosaccharides of protein-polysaccharide were xylose, mannose, galactose, glucose and fructose in order and its major amino acids were glutamic acid, serine and aspartic acid. The antitumor activity of the protein-polysaccharide at a dose of 0.5mg/kg/day or 5mg/kg/day against Sarcoma-180 in mice were 20.9% and 43.9%, respectively.
