Dose/concentration response in echinoderm coelomocytes.

<p>Increase in DNA damage (strand scission factor, SSF, Fast Micromethod) with increasing concentration of H₂O₂ (<b>A</b>, <b>C</b>, <b>E</b>, and <b>G</b>) or dose of UV-C (<b>B</b>, <b>D</b>, <b>F</b>, and <b>H</b>) after acute exposure of coelomocytes from <i>T. ventricosus</i> (<b>A</b> and <b>B</b>, n = 5), <i>L. variegatus</i> (<b>C</b> and <b>D</b>, n = 11–12), <i>E. l. lucunter</i> (<b>E</b> and <b>F</b>, n = 6–7), and <i>I. badionotus</i> (<b>G</b> and <b>H</b>, n = 8). Data are means ± s.e.m.
