| Abstract: | Abstract. Agglutination-inhibition, precipitation and precipitation-inhibition tests have been performed with 2 sponge and 4 snail extracts using as inhibitors a number of biological materials and some glycoproteins and glycolipids. Some human salivas and fluids from ovarian pseudomucinous cysts inhibited, others did not inhibit. Inhibiting power was unrelated to presence of ABH substances. Some snail and seed extracts inhibited haemagglutination by Axinella sp. extract and some snail extracts haemagglutination by Cliona celata extract. Axinella sp. extract precipitated non-haemagglutinating Achatina granulata and Hedleyella falconeri snail extracts; this precipitation was inhibited by the same sugars which also inhibit haemagglutination by Axinella sp. extract. |
