Abstract

The mutagenic potential of furfural was evaluated by means of the chromosome loss test in germ cells and the wing spot test in somatic cells of Drosophila melanogaster. The chromosome loss test was carried out employing repair-proficient as well as repair-deficient females. Males carried the compound Y chromosome, BSYy+. Two routes of administration were used: injection and feeding of adult males. Genetic damage was demonstrable after matings of treated males with females carrying the excision repair-deficient mutant mei-9a. The somatic mutation and recombination test was carried out treating 72-h transheterozygous mwh+/+flr3 larvae. Acute treatment of larvae was chosen as the method of exposure. Evidence indicates that furfural induces somatic damage as measured in the wing spot test.

摘要

通过果蝇生殖细胞的染色体丢失试验和体细胞的翅斑试验评估了糠醛的诱变潜力。染色体丢失试验使用了修复能力正常以及修复缺陷的雌性果蝇进行。雄性果蝇携带复合Y染色体,即BSYy+。采用了两种给药途径:对成年雄性果蝇进行注射和喂食。在用携带切除修复缺陷突变体mei-9a的雌性果蝇与经处理的雄性果蝇交配后,可证明存在遗传损伤。体细胞突变和重组试验是对72小时龄的mwh+/+flr3反式杂合幼虫进行处理。选择对幼虫进行急性处理作为暴露方法。有证据表明,如在翅斑试验中所测定的那样,糠醛会诱发生物体细胞损伤。
