Investigation of the Effect of Rosmarinic Acid on Cyclophosphamide-Induced Gonadal Toxicity

摘要

style="font-family:Verdana;">The aim of this study was to investigate the effect of rosmarinic acid against gonadal toxicity caused by cyclophosphamide, an important anticancer drug. A total of 28 rats were divided into 4 groups, with 7 animals in each group. The groups were created as follows;Group 1 (control) (n = 7): Subjects received only 1 ml of 0.9% saline solution per day intraperitoneally for 14 days. Group 2 (Rosmarinic Acid) (n = 7): The subjects were given 20 mg/kg Rosmarinic acid intraperitoneally for 14 days. Group 3 (Cyclophosphamide) (n = 7): Only 1 ml of 0.9% saline solution was administered intraperitoneally to the subjects for the first 7 days. Cyclophosphamide 20 mg/kg per day was administered intraperitoneally for the last 7 days (from the 8 style="font-family:Verdana;">th style="font-family:Verdana;"> day) style="font-family:Verdana;">. Group 4 (Rosmarinic Acid style="font-family:;" "=""> style="font-family:;" "=""> style="font-family:Verdana;">+ Cyclophosphamide) (n = 7): The subjects were given 20 mg/kg Rosmarinic acid daily intraperitoneally for 14 days. From the 8 style="font-family:Verdana;">th style="font-family:Verdana;"> day of the experiment to the end of the experiment (last 7 days of the experiment), 20 mg/kg cyclophosphamide was given intraperitoneally daily. At the end of the experiment, body weights of all rats were measured first. Afterwards, the weights of testicular tissue samples were measured and the averages of the weights were taken. Routine tissue follows up was performed on the testicular tissues taken. Hematoxylin-eosin staining was applied to tissue sections of 5 μm thickness. As a result of the statistical analysis, it was determined that cyclophosmadine decreased body and testicular weight, but rosmarinic acid had a protective effect on the contrary. It was concluded that cyclophosmadine caused damage to the basement membrane structure, Sertoli, Leydig and germ cells, but these structures were preserved due to the protective effect of rosmarinic acid. Despite the toxic effect of CP, rosmarinic acid is thought to have a significant curative effect on the spermatogenetic process and seminiferous tubule structure in the gonads.
