Abstract
1) It was tried to separate the blood group lipoids by the aid of organic solvents from human gastric mucosa and gastric cancers.
2) All of the preparations of the A, B and O group-lipoids had similar composition with respect to N-, P- and carbohydrate-content and similar solubilities.
3) They rotated D light to the right but slightly.
4) Group A lipoid from gastric cancer was serologically much less active than the corresponding lipoid from the normal mucosa.
5) An assumption was expressed that the liver metastasis of gastric cancer contains a group lipoid same as the one in its original growth.
