0.0343ppm-0.067ppm溴乙酰胺浸泡钉螺卵后,从单细胞期发育到原肠胚期,其形态出现畸形;但发育到担轮-缘膜幼虫期和完成变态的缘膜幼虫期螺卵出现畸形胚所需浓度比囊胚期、原肠胚期螺卵出现畸形胚的浓度为高。溴乙酰胺浸泡螺卵,时间相同,浓度越高,滞育率越高,而时间越长,阻碍螺卵发育所需浓度越低,孵化率也越低。经溴乙酰胺作用后,雌螺产卵量明显降低,成熟钉螺卵巢明显萎缩。用~3H标记的溴乙酰胺浸泡钉螺,表明溴乙酰胺可进入钉螺体内的螺卵中,其放射性含量随浸泡钉螺的药物浓度增高而增多。这一结果为以后研究灭螺药对螺卵的作用机制,提供了一种新的方法。
0.0343ppm-0.067ppm bromoacetamide impregnated snail eggs, from the single-cell stage to the gastrulation stages, the morphology deformity; but the development of the carrier-rim larvae and metamorphosis periuria larvae spiro egg appear The deformity embryo required concentration higher than the blastocyst stage, gastrulation embryo embryo morphological embryo concentration is high. Bromoacetamide soaked in spiro eggs, the same time, the higher the concentration, the higher the rate of diapause, and the longer the time required to prevent the development of spiral eggs the lower the concentration required, the lower the hatching rate. By bromoacetamide role, female spawning amount was significantly reduced, mature snail ovary significantly atrophy. Soaking snails with ~ 3H labeled bromoacetamide indicated that bromoacetamide could enter into the snail eggs in the snail and its radioactive content increased with the drug concentration of the snail soaked. This result provides a new method for the future study of the mechanism of action of snail control on snail eggs.
