Abstract

In this study, the protective effect of astaxanthin (AST) against cyclophosphamide (CP) induced adult rat heart damage was investigated. Eighteen rats were divided into 3 groups as Group 1: control, Group 2: cyclophosphamide and Group 3: cyclophosphamide + astaxanthin. The CP group, received a 200 mg/kg single dose intraperitoneal (i.p.) injection of CP on the seventh day of the experiment, while the control group received no treatment. For CP+AST group 25 mg/kg/day AST administered by oral gavage on days 1-7 and on the 7th day 200 mg/kg/day CP was administered by i.p injection. On the 8th day, the rats were sacrificed by exsanguination and the hearts were dissected. Histopathological examinations were performed by Hematoxylin&Eosin (H&E), Masson Trichrome and Periodic Acid-Schiff (PAS) staining methods; Annexin-V and Anti-NOX2/gp91phox analyzes were performed by flow cytometry. In histological evaluation of the CP Group; disruptions in cardiac histology and increased PAS(+) staining were observed. These findings were reduced in the CP+AST group compared to the CP group. According to flow cytometry measurements, there was an increase in Annexin-V and Anti-NOX2/gp91phox bound cells in the CP group. With the AST pretreatment, in the CP+AST group Annexin-V and Anti-NOX2/gp91phox bound cell level showed decrease. Based on our study's data, CP may alter cardiac histology and have a negative impact on apoptosis and oxidative damage processes. Astaxanthin may ameliorate these effects of CP on the heart. To enhance the assessment of this protective effect, we propose conducting future research utilizing varied dosages, application durations and advanced analytical techniques.

虾青素对环磷酰胺所致大鼠心脏损伤的组织学和流式细胞术评价。
本研究探讨虾青素(AST)对环磷酰胺(CP)诱导的成年大鼠心脏损伤的保护作用。18只大鼠分为3组,1组为对照组,2组为环磷酰胺组,3组为环磷酰胺+虾青素组。CP组于实验第7天给予CP单剂量腹腔注射200 mg/kg,对照组不给予任何治疗。CP+AST组在第1 ~ 7天灌胃AST 25 mg/kg/d,第7天静脉注射CP 200 mg/kg/d。第8天放血处死大鼠,解剖心脏。采用苏木精&伊红(H&E)、马松三色、周期性酸-希夫(PAS)染色法进行组织病理学检查;流式细胞术检测Annexin-V和Anti-NOX2/gp91phox。CP组组织学评价;观察到心脏组织学破坏和PAS(+)染色增加。与CP组相比,CP+AST组的这些发现有所减少。流式细胞术检测发现,CP组Annexin-V和Anti-NOX2/gp91phox结合细胞增多。经AST预处理后,CP+AST组Annexin-V和Anti-NOX2/gp91phox结合细胞水平降低。根据我们的研究数据,CP可能会改变心脏组织学,并对细胞凋亡和氧化损伤过程产生负面影响。虾青素可以改善CP对心脏的这些影响。为了加强对这种保护作用的评估,我们建议利用不同的剂量、应用时间和先进的分析技术进行未来的研究。

期刊介绍: Drug and Chemical Toxicology publishes full-length research papers, review articles and short communications that encompass a broad spectrum of toxicological data surrounding risk assessment and harmful exposure. Manuscripts are considered according to their relevance to the journal. Topics include both descriptive and mechanics research that illustrates the risk assessment implications of exposure to toxic agents. Examples of suitable topics include toxicological studies, which are structural examinations on the effects of dose, metabolism, and statistical or mechanism-based approaches to risk assessment. New findings and methods, along with safety evaluations, are also acceptable. Special issues may be reserved to publish symposium summaries, reviews in toxicology, and overviews of the practical interpretation and application of toxicological data.
