Beschreibung:
A hydrostatic pressure of only 68 atmospheres prevented swimming Paramecium caudatum from "avoiding" or reversing direction; 170 atmospheres stopped or decreased forward velocity by more than 75 percent. A decompression of 40 atmospheres invoked a single reversal, even at ,80 atmospheres. In contrast, 170 atmospheres did not significantly affect swimming behavior of paramecium "models" that were reactivated in a solution containing adenosine triphosphate and magnesium ions after their membrane had been disrupted by Triton X-100.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Otter, T -- Salmon, E D -- New York, N.Y. -- Science. 1979 Oct 19;206(4416):358-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/482945" target="_blank"〉PubMed〈/a〉
