Abstract

This paper sheds light on the mechanism of action, potential effects and implication of Senna alata on fish health and ecosystem. Senna alata is renowned for its medicinal properties and ornamental value but is also recognized for its potential toxicity, particularly to aquatic organisms Understanding the toxicity of Senna alata to Clarias gariepinus fingerlings is essential for sustainable aquaculture practices and environmental conservation efforts. 250 juveniles of C. gariepinus were procured from E. I farm Limited in Ikot Ekpene, Akwa Ibom State. Water quality tests were carried out to ensure that optimum water conditions were maintained and that the results obtained were solely due to the effects of the treatments (toxicants) on the fish samples. Chronic toxicity bioassay was done to determine the toxicity of the extract on the blood parameters and tissues of sensitive organs of the exposed fish. The bioassay was designed to be intermediate termed chronic test with 14 days exposure using sub-lethal concentrations of the treatment (0.0gm/, 0.18mg/L, 0.27mg/L. 0.4mg/L, 0.60mg/L, 0.90mg/L). Toxicology dose response (fish mortality) was subjected to detailed analysis using Statistical Package for Social Sciences (SPSS) 22.0. Data were analyzed using descriptive statistics. Senna alata exerted a toxic effect on the fish in the present study and toxicity increased with increased concentration. These findings underscore the potential adverse effects of prolonged exposure to Senna alata on the physiological and cellular integrity of the fish. Intriguingly, the absence of pathological changes in the control groups suggests a distinct response attributable to the treatment. This highlights the importance of continued monitoring and assessment of the impacts of Senna alata on aquatic organisms and ecosystem, emphasizing the need for further research to elucidate the underlying mechanisms and potential long-term consequences.
研究番泻叶提取物对幼鱼血液学和组织病理学的影响
本文揭示了番泻叶的作用机制、潜在影响以及对鱼类健康和生态系统的影响。番泻叶因其药用价值和观赏价值而闻名,但同时也被认为具有潜在毒性,尤其是对水生生物的毒性。了解番泻叶对花蛤幼鱼的毒性对可持续水产养殖实践和环境保护工作至关重要。从阿夸伊博姆州 Ikot Ekpene 的 E. I 农场有限公司采购了 250 尾赤鲤幼鱼。进行了水质测试,以确保保持最佳的水质条件,并确保所获得的结果完全是由处理(毒物)对鱼类样本的影响造成的。进行了慢性毒性生物测定,以确定提取物对暴露鱼类的血液参数和敏感器官组织的毒性。生物测定设计为中间慢性试验,使用亚致死浓度(0.0 毫克/升、0.18 毫克/升、0.27 毫克/升、0.4 毫克/升、0.60 毫克/升、0.90 毫克/升)进行 14 天暴露。使用社会科学统计软件包(SPSS)22.0 对毒理学剂量反应(鱼类死亡率)进行了详细分析。数据采用描述性统计进行分析。在本研究中,番泻叶对鱼类产生了毒性作用,而且毒性随着浓度的增加而增加。这些发现强调了长期接触番泻叶对鱼类生理和细胞完整性的潜在不利影响。耐人寻味的是,对照组没有出现病理变化,这表明治疗产生了明显的反应。这凸显了持续监测和评估番泻叶对水生生物和生态系统影响的重要性,强调了进一步研究以阐明其潜在机制和长期后果的必要性。
