摘要:

目的 以国内广布种日本三角涡虫(Dugesia japonica)为受试动物,探讨三类生物因子对涡虫生殖和再生的影响。 方法 选择与生殖相关的激素(雌二醇、甲基睾丸素),生物胺(5-羟色胺、多巴胺)和D-氨基酸(D-色氨酸、D-精氨酸、D-苯丙氨酸)对日本三角涡虫进行急性毒性实验,用SPSS 17. 0统计学软件计算出适宜的实验浓度,对整体及再生涡虫进行培养,观察并记录实验现象。 结果 雌二醇、5-羟色胺、D-色氨酸和D-苯丙氨酸处理组分别引起20%、40%、20%和20%涡虫卵巢及交配器官的发育;而多巴胺则引起40%~50%涡虫生殖腺退化。另外,5-羟色胺处理组涡虫头部再生速度加快,而多巴胺处理组则头部再生速度减慢。结论 雌二醇、5-羟色胺、D-色氨酸和D-苯丙氨酸能够诱导涡虫生殖腺的发育,并且5-羟色胺促进涡虫头部再生;多巴胺则引起涡虫生殖腺退化并对涡虫再生有抑制作用。

Abstract:

Objective To investigate the effects of the three reproductive-relative factors on gonads and regeneration in planarians. Methods In this study, the planarians Dugesia japonica were cultured with three reproductive-relative factors: the hormones [estradiol (E2), methyltestosteronum(MT)], biogenic amine [5-hydroxy-tryptamine (5-HT),dopamine (DA)] and D-amino acids (D-tryptophan, D-arginine, D-phenylalanine). The cultured concentration was calculated by SPSS17.0 after the acute toxicity experiment, and the experimental phenomena were recorded. Results E2, 5-HT, D-tryptophan and D-phenylalanine improved the gonads development, which proportions were 20%, 40%, 20%, and 20% respectively, but DA made the gonads atrophy in 40% or 50% planarians. Besides, 5-HT increased speed of regeneration, while DA inhibited it during planarians regeneration. Conclusion E2, 5-HT, D-tryptophan and D-phenylalanine improved the gonads development, and 5-HT increased speed of regeneration; DA inhibited the gonads and regeneration.
