Effect of an Extract from the Egyptian Sea Cucumber,Bohadschia marmorata,on Methotrexate-Induced Hepatorenal Toxicity in Male Mice

Background: The sea cucumber, Bohadschia marmorata, is a marine echinoderm consumed and used as a medication. Extract of this species displays a broad spectrum of bioactivity, such as antifungal, antibacterial, immunomodulatory, and cytotoxic properties. This investigation explored sea cucumber extract for hepatorenal protection against the toxicity of methotrexate (MTX). Methods: Four groups of mice were divided into G1: control, G2: MTX treated, G3: B. marmorata extract-treated daily for 14 days, and G4: B. marmorata extract and MTX treated. Results and Conclusions: Biochemical analysis and histopathological examination of liver tissue showed that administration of MTX increased serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), lowered levels of serum albumin, total protein, Superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH). Administration of B. marmorata extract to MTX- injected mice significantly reversed the increase in serum levels of liver enzymes and induced a significant elevation in serum albumin and total protein levels. SOD, CAT, and GSH levels returned to nearly normal levels. Histopathological examination indicated fewer signs of toxicity in liver and kidney tissues of mice treated with both extract and MTX compared to MTX treatment alone. An extract of B. marmorata will protect mice from hepatorenal toxicity induced by MTX.
