Inhibition by amiloride and by Na+-depletion of A23187-stimulated arachidonic acid and histamine release from rat mast cells.

abstract：:We have found that the sign of phototaxis, i.e. the direction of phototactic migration either towards or away from the light source, of wild-type Chlamydomonas reinhardtii depends on its photosynthetic activity. This accounts for the frequently reported transient positive phototaxis that precedes a negative phototaxis...
