Notes
The relationship between the locomotive velocity of amoeba which had not been fed for 24 hr and the concentration of the test solutions was examined. With solutions of L-amino acids, protein substances, and alcian blue 8GS, an increase in velocity began at very low concentrations, reaching a maximum at a higher concentration and as the concentration increased further, the velocity fell to zero. In contrast, no increase was observed with D-glutamic acid and beta-alanine. Moreover, the velocity of well fed amoebae did not increase significantly even in L-amino acid solution. These results may suggest a correlation between orthokinesis and amoeboid phagocytosis.
