Notes:
We have previously reported that Ca2+ influx into the mitochondria of Hymenolepis diminuta, a rat intestinal eestode, takes place through an electrophoretic uniport system. Sodium and lithium were found to induce efflux of 45Ca2+ from the mitochondria of H. diminuta. The two cations induced the efflux in a hyperbolic and linear fashion, respectively. The efflux as well as an exchange of external Ca2+ with internal 45Ca2+ was inhibited by lanthanum. The type of Ca2+ transport system in the cestode organelle has been discussed and compared with that of the host (mammalian) counterpart.
