摘要

我们研究了施用乙二胺四乙酸 14 天和 28 天对镉诱导的池塘田螺 Lymnaea stagnalis (Linnaeus, 1758)的治疗效果。接触亚致死浓度镉(63.4 毫克/升)28 天后,田螺的组织受到损伤。采用评分系统评估了 EDTA 对镉引起的损伤的治疗效果。镉暴露导致组织病理学变化,包括粘膜炎、色素和蛋白细胞增加、足上皮脱屑、肌肉纤维损伤、结缔组织细胞萎缩,以及套膜和肝胰腺中脂质空泡增加。不过,用乙二胺四乙酸(2.00 mL/L,28 天)处理蜗牛后,这些变化并不严重,这表明乙二胺四乙酸降低了蜗牛对重金属毒性的易感性。

Histopathological Evaluation of the Curative Effects of EDTA on Lymnaea stagnalis Exposed to Subacute Cadmium.

Histopathological Evaluation of the Curative Effects of EDTA on Lymnaea stagnalis Exposed to Subacute Cadmium.

We investigated the therapeutic effects of EDTA application for 14 and 28 days on cadmium (Cd) induced pond snail Lymnaea stagnalis (Linnaeus, 1758). The sublethal concentration of cadmium (63.4 mg/l Cd) caused tissue damages to the snail after an exposure for 28 days.In the groups treated with EDTA, the concentration of Cd in the foot, mantle and hepatopancreas tissues showed significantly decreased during the recovery period. The curative effects of EDTA on Cd-induced damage were assessed using a scoring system. Cadmium exposure led to histopathological changes including increased mucositis, pigment and protein cells, foot epithelium desquamation, muscle fibril damage, connective tissue cell atrophy, and increased lipid vacuoles in the mantle and hepatopancreas. However, these changes were less severe in snails treated with EDTA (2.00 mL/L for 28 day), indicating that EDTA reduces their susceptibility to heavy metal toxicity.
