Morchella esculenta (L) Pers. is an excellently edible and delicious morel mushroom found growing in the temperate forests. The mycelium of this mushroom is widely used as a flavouring agent. The current investigation was undertaken to explore the protective effect of the aqueous-ethanol extract of cultured mycelium of M. esculenta against cisplatin and gentamicin induced acute renal toxicity in Swiss albino mice. Cisplatin and gentamicin when administered induced a marked renal failure, characterized by a significant increase in serum urea and creatinine concentrations. Treatment with the extract at 250 and 500mg/kg body weight decreased the cisplatin and gentamicin induced increase in serum creatinine and urea levels. Treatment with the extract also restored the depleted antioxidant defense system. The decreased activity of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and reduced glutathione (GSH) in the kidneys consequent to cisplatin and gentamicin administration was significantly elevated. The enhanced renal antioxidant defense system also prevented the tissue lipid peroxidation. The experimental results suggest that aqueous-ethanol extract of morel mushroom, M. esculenta mycelium protected cisplatin and gentamicin induced nephrotoxicity possibly by enhancing renal antioxidant system. The findings thus suggest the potential therapeutic use of morel mushroom mycelium as a novel nephroprotective agent.
羊肚菌(Morchella esculenta (L) Pers.)是一种美味可口的可食用羊肚菌,生长在温带森林中。这种蘑菇的菌丝体被广泛用作调味剂。本研究旨在探讨羊肚菌培养菌丝体的水乙醇提取物对顺铂和庆大霉素诱导的瑞士白化小鼠急性肾毒性的保护作用。顺铂和庆大霉素给药后会导致明显的肾衰竭,表现为血清尿素和肌酐浓度显著升高。以250和500mg/kg体重的提取物进行治疗,可降低顺铂和庆大霉素诱导的血清肌酐和尿素水平升高。提取物治疗还恢复了耗尽的抗氧化防御系统。顺铂和庆大霉素给药后肾脏中超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽过氧化物酶(GPx)活性降低以及还原型谷胱甘肽(GSH)减少的情况均显著升高。增强的肾脏抗氧化防御系统还防止了组织脂质过氧化。实验结果表明,羊肚菌菌丝体的水乙醇提取物可能通过增强肾脏抗氧化系统来保护顺铂和庆大霉素诱导的肾毒性。因此,这些发现表明羊肚菌菌丝体作为一种新型肾保护剂具有潜在的治疗用途。
