草药酸氨酸 (GLA) 会导致DNA损伤,并减少人类淋巴细胞和牛血细胞中的细胞增殖. 它还对牛生长和蛋生产产生了负面影响,这表明了对环境有毒性的担忧.
科学领域:
- 环境毒理学环境毒理学
- 遗传学 遗传学 是一个
- 生态毒理学 生态毒理学
背景情况:
- 酸氨酸 (GLA) 是一种有机酸除草剂,广泛释放到环境中.
- 对其潜在的基因毒性和细胞效应存在担忧,但研究是有限的.
- 了解GLA对非标生物和人类细胞的影响至关重要.
研究的目的:
- 评估GLA对人类淋巴细胞和Lymnaea stagnalis*血细胞的基因毒性.
- 评估GLA对细胞增殖的细胞毒性影响.
- 调查GLA对Lymnaea stagnalis的生殖健康和生长的影响.
主要方法:
- 在体外和体内微核测定是在培养的人类淋巴细胞和L. stagnalis*血细胞上进行的.
- 测试了六种不同的GLA度,范围从0.010到0.500微克/毫升.
- 还测量了L. stagnalis*的细胞增殖,卵子生产和身体生长.
主要成果:
- 在人体淋巴细胞中,GLA显著增加了微核的频率,其度≥0.100μg/mL,在L. stagnalis*血细胞中,其度≥0.200μg/mL.
- 在大多数测试的GLA度中观察到细胞增殖的显著减少.
- 在暴露于GLA的*L. stagnalis*中,观察到卵产量和身体生长的减少.
结论:
- 在人类淋巴细胞和L. stagnalis*血细胞中,GLA会诱导基因组和细胞损伤.
- 这种除草剂表现出细胞毒性作用,损害细胞增殖.
- GLA对*L. stagnalis*的生殖健康和生长产生负面影响,突出了其生态毒理学风险.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
