毒理学实验是通过研究毒物对生物体的影响，揭示其毒性机制和评估潜在健康风险的科学研究。该领域包括急性毒性、亚急性毒性、慢性毒性、致突变性和致癌性等方面的研究。实验通常使用小鼠、大鼠、细胞培养等模型，采用各种毒性评估方法，如生化检测、组织病理学和基因表达分析。毒理学实验为药物安全性评估、环境污染研究和毒物学研究提供了关键信息。

Toxicology experiments are scientific research that studies the effects of poisons on living organisms, reveals their toxicity mechanisms, and evaluates potential health risks. This field includes research on acute toxicity, subacute toxicity, chronic toxicity, mutagenicity and carcinogenicity. Experiments usually use models such as mice, rats, and cell culture, and adopt various toxicity assessment methods, such as biochemical testing, histopathology, and gene expression analysis. Toxicology experiments provide key information for drug safety assessment, environmental pollution research, and toxicology research.
