采用急性实验的常规方法—死亡概率法,用甲醛及几种抗生素对刺参幼参的急性毒性试验,结果表明:甲醛、氯霉素、环丙沙星、盐酸土霉素对刺参幼参24h半致死浓度(LC50)分别为:15.4×10-6、146.9×10-6、173.6×10-6、263.4×10-6;48h半致死浓度(LC50)分别为:13.6×10-6、107×10-6、144.4××10-6、244.7×10-6;安全浓度(SC)分别为:3.18×10-6、17.03×10-6、29.97×10-6、63.35×10-6。
The acute toxicity test of sea cucumber sea cucumber with formaldehyde and several antibiotics was carried out using the conventional method of acute test - death probability method. The results showed that formaldehyde, chloramphenicol, ciprofloxacin and oxytetracycline hydrochloride The median lethal concentrations (LC50) of 24h were respectively: 15.4 × 10-6,146.9 × 10-6,173.6 × 10-6,263.4 × 10-6; LC50 of 48h were 13.6 × 10-6, 107 × 10-6,144.4 ×× 10-6,244.7 × 10-6; the safe concentration (SC) were 3.18 × 10-6, 17.03 × 10-6, 29.97 × 10-6, 63.35 × 10-6 .
