a green alga, attenuates the kidney and liver dysfunctions in rats induced by acetaminophen.

Acetaminophen (AAP) is an analgesic-antipyretic drug which is considered safe at recommended dose, but its overuse may induce renal and hepatic injuries. Marine macro algae have great potential against drug-induced renal and hepatic dysfunctions. The present study described the reno-protective and hepato-protective effects of the ethanol extract of an edible green alga and its fractions (n-hexane, chloroform and methanol) against AAP toxicity. In the 1 set of experiment, rats were divided into five groups. Of which two were treatment groups beside three controls, the first treatment group was given ethanol extract of alone and the second group was given the same extract with AAP. In the 2 set of experiment, rats were divided into nine groups, of which three treatment groups administered -hexane, chloroform and methanol fractions of ethanol extract of respectively while other three treatment groups received the same fractions individually with AAP. On the 11 day, rats were decapitated after 12 h of fasting from both sets, blood samples were collected for assessment of biochemical parameters and kidney tissues were used for determination of oxidants and antioxidants. Histopathological assessment was also done in kidney tissues. A single dose of AAP (600 mg/kg) affected kidney markers including creatinine, urea and blood urea nitrogen (BUN) and hepatic enzymes. Ethanolic extract of normalized kidney and liver markers in AAP intoxicated rats. AAP also reduced glutathione (GSH) in kidney tissues and altered kidney architecture, which were improved by ethanolic extract and chloroform soluble fraction of A total of 14 polyunsaturated fatty acids were identified from chloroform soluble fraction of by GC-MS and assumed these may be involved in protective activities of .
