The present study aimed to determine the genoprotective activity and safety of leave and stem extracts against cyclophosphamide (CP)-induced genotoxicity utilizing Swiss albino mice. Animals were divided into 14 groups for subacute treatment with either or extracts daily for 28 days. The extract doses selected were 100, 200 or 400 mg/kg b.w administered orally alone or combined with CP (50 mg/kg b.w. intraperitoneally daily for 5 days). Analyses performed included the comet assay, micronucleus test (MN) in bone marrow cells and sperm head abnormality assay (SHA). and extracts induced no significant genotoxic effects on somatic and germ cells. In contrast, for all cells examined and extracts inhibited DNA damage initiated by CP. Taken together data demonstrated that both plant extracts did not exhibit marked genotoxic effects but displayed potential chemoprotective properties against CP-induced genotoxicity in Swiss mice.
本研究旨在利用瑞士白化小鼠确定叶和茎提取物对环磷酰胺(CP)诱导的遗传毒性的遗传保护活性和安全性。动物被分为 14 组,用提取物进行亚急性治疗,每天口服一次,剂量分别为 100、200 或 400mg/kg b.w.,或与 CP(50mg/kg b.w.,每日腹腔内注射,连续 5 天)联合使用。进行的分析包括彗星试验、骨髓细胞微核试验(MN)和精子头畸形试验(SHA)。叶和茎提取物对体细胞和生殖细胞均无明显遗传毒性作用。相反,对于所有检查的细胞,叶和茎提取物均抑制 CP 引发的 DNA 损伤。综上所述,这些数据表明,两种植物提取物均未表现出明显的遗传毒性作用,但对 CP 诱导的瑞士小鼠遗传毒性具有潜在的化学保护作用。
