Fig. 4From: Establishment of an analytical method for butaphosphan (BTP), a stress-attenuating agent, and its application in the preliminary pharmacokinetic evaluation of residues in olive flounder Paralichthys olivaceusMuscle concentration of BTP after intramuscular injection in olive flounder. Mean values were presented without error bars for clarity (n = 10 for each time point). Levels at time 0 (non-detectable levels, n = 10) were omitted to avoid complication, and the first symbols denote levels at 0.5 h after injectionBack to article page
