Oxidative stress plays a crucial role in the development of drug induced nephrotoxicity. The study aimed to determine the nephroprotective and ameliorative effects of Carica papaya seed extract in paracetamol-induced nephrotoxicity in rats.
To carry out phytochemical screening of Carica papaya, measure serum urea, creatinine and uric acid and describe the histopathological status of the kidneys in the treated and untreated groups.
Phytochemical screening of the extract was done. Thirty two adult male Wistar rats were divided into four groups (n= 8 in each group). Group A (control) animals received normal saline for seven days, group B (paracetamol group) received normal saline, and paracetamol single dose on the 8th day. Group C received Carica papaya extract (CPE) 500 mg/kg, and paracetamol on the 8th day, while group D, rats were pretreated with CPE 750 mg/kg/day,and paracetamol administration on the 8th day. Samples of kidney tissue were removed for histopathological examination.
Screening of Carica papaya showed presence of nephroprotective pytochemicals. Paracetamol administration resulted in significant elevation of renal function markers. CPE ameliorated the effect of paracetamol by reducing the markers as well as reversing the paracetamol-induced changes in kidney architecture.
Carica papaya contains nephroprotective phytochemicals and may be useful in preventing kidney damage induced by paracetamol.
氧化应激在药物性肾毒性的发展中起关键作用。本研究旨在确定番木瓜籽提取物对大鼠扑热息痛诱导的肾毒性的肾保护和改善作用。
对番木瓜进行植物化学筛选,测定血清尿素、肌酐和尿酸,并描述治疗组和未治疗组肾脏的组织病理学状况。
对提取物进行植物化学筛选。将32只成年雄性Wistar大鼠分为四组(每组n = 8)。A组(对照组)动物连续7天接受生理盐水,B组(扑热息痛组)接受生理盐水,并在第8天给予单剂量扑热息痛。C组在第8天接受500 mg/kg番木瓜提取物(CPE)和扑热息痛,而D组大鼠预先用750 mg/kg/天的CPE处理,并在第8天给予扑热息痛。取出肾组织样本进行组织病理学检查。
番木瓜的筛选显示存在肾保护植物化学物质。扑热息痛给药导致肾功能标志物显著升高。CPE通过降低标志物以及逆转扑热息痛诱导的肾脏结构变化,改善了扑热息痛的作用。
番木瓜含有肾保护植物化学物质,可能有助于预防扑热息痛引起的肾损伤。
