Prevention of hepatorenal toxicity with Sonchus asper in gentamicin treated rats

<p>Abstract</p> <p>Background</p> <p><it>Sonchus asper </it>possesses antioxidant capacity and is used in liver and kidney disorders. We have investigated the preventive effect of methanolic extract of <it>Sonchus asper </it>(SAME) on the gentamicin induced alterations in biochemical and morphological parameters in liver and kidneys of Sprague-Dawley male rat.</p> <p>Methods</p> <p>Acute oral toxicity studies were performed for selecting the therapeutic dose of SAME. 30 Sprague-Dawley male rats were equally divided into five groups with 06 animals in each. Group I received saline (0.5 ml/kg bw; 0.9% NaCl) while Group II administered with gentamicin 0.5 ml (100 mg/kg bw; i.p.) for ten days. Animals of Group III and Group IV received gentamicin and SAME 0.5 ml at a dose of 100 mg/kg bw and 200 mg/kg bw, respectively while Group V received only SAME at a dose of 200 mg/kg bw. Biochemical parameters including aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), γ-glutamyltransferase (γ-GT), total cholesterol, triglycerides, total protein, albumin, creatinine, blood urea nitrogen (BUN), total bilirubin and direct bilirubin were determined in serum collected from various groups. Urinary out puts were measured in each group and also assessed for the level of protein and glucose. Lipid peroxides (TBARS), glutathione (GSH), DNA injuries and activities of antioxidant enzymes; catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) were determined in liver and renal samples. Histopathological studies of liver and kidneys were also carried out.</p> <p>Results</p> <p>On the basis of acute oral toxicity studies, 2000 mg/kg bw did not induce any toxicity in rats, 1/10^thof the dose was selected for preventive treatment. Gentamicin increased the level of serum biomarkers; AST, ALT, ALP, LDH, γ-GT, total cholesterol, triglycerides, total protein, albumin, creatinine, BUN, total and direct bilirubin; as were the urinary level of protein, glucose, and urinary output. Lipid peroxidation (TBARS) and DNA injuries increased while GSH contents and activities of antioxidant enzymes; CAT, POD, SOD decreased with gentamicin in liver and kidney samples. SAME administration, dose dependently, prevented the alteration in biochemical parameters and were supported by low level of tubular and glomerular injuries induced with gentamicin.</p> <p>Conclusion</p> <p>These results suggested the preventive role of SAME for gentamicin induced toxicity that could be attributed by phytochemicals having antioxidant and free radical scavenging properties.</p

Notes for genera: basal clades of Fungi (including Aphelidiomycota, Basidiobolomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Zoopagomycota)

Compared to the higher fungi (Dikarya), taxonomic and evolutionary studies on the basal clades of fungi are fewer in number. Thus, the generic boundaries and higher ranks in the basal clades of fungi are poorly known. Recent DNA based taxonomic studies have provided reliable and accurate information. It is therefore necessary to compile all available information since basal clades genera lack updated checklists or outlines. Recently, Tedersoo et al. (MycoKeys 13:1--20, 2016) accepted Aphelidiomycota and Rozellomycota in Fungal clade. Thus, we regard both these phyla as members in Kingdom Fungi. We accept 16 phyla in basal clades viz. Aphelidiomycota, Basidiobolomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Zoopagomycota. Thus, 611 genera in 153 families, 43 orders and 18 classes are provided with details of classification, synonyms, life modes, distribution, recent literature and genomic data. Moreover, Catenariaceae Couch is proposed to be conserved, Cladochytriales Mozl.-Standr. is emended and the family Nephridiophagaceae is introduced
