以往一些研究证实,两栖类幼虫对高毒性的黄曲霉毒素(AFT)是敏感的,这些毒素的致死作用表现为:LD_(50)值低,亚致死剂量的AFT对哈士蟆幼虫具有致畸作用,主要为肢体畸形。其他霉菌毒素是否对两栖类幼虫也有害则不了解。为此,作者选用长度约为1cm的哈士蟆幼虫(6只一组)和长度为1.5cm的1周令的T. alpestris蝌蚪(10只一组),用AFT-B_1、展青霉毒素、红色青霉毒素B、杂色曲霉毒素和二醋酸基藨草镰刀菌醇(diacetoxyscirpenol)等进行了研究。实验所用的各种毒素均溶解在
Previous studies have confirmed that amphibian larvae are sensitive to highly toxic aflatoxins (AFTs) and that the lethal effects of these toxins are as follows: LD 50 low, sublethally AFT has teratogenic effects on hawk larvae Role, mainly limb deformities. Whether other mycotoxins are harmful to amphibian larvae is unknown. To this end, the authors selected the hawk larvae with a length of about 1 cm (6 groups) and the 1 week-old T. alpestris tadpoles (10 groups) with a length of 1.5 cm. AFT-B_1, , Red penicillin B, versicolor toxin and diacetoxyscirpenol, and the like. The various toxins used in the experiment were dissolved in
