| Abstract: | 1. Intact, isolated nematocysts from the non-toxic, freshwater coelenterate Hydra oligactis contain soluble material(s) capable of producing a sustained increase in the rate of developed force in the vertebrate myocardium. 2. The positive inotropic effects of this material(s) appear grossly comparable to those described for Anthopleurin-A (AP-A) and Toxin II (ATX-II) from sea anemones. 3. The effects of the nematocyst material are distinct from those of known vasoactive peptides reported to occur in Hydra. |
