Objective: Gentamicin(GM) is a commonly used aminoglycoside antibiotic, however, renal toxicity has limited its usage. The present study was designed to evaluate the ameliorative effect of cistanche deserticola on GM-induced nephrotoxicity in rats.Methods: The nephrotoxicity in rats was induced by intraperitoneal administration of GM(100 mg/kg)for 10 consecutive days. Glomerular filtration rate, blood urea nitrogen, creatinine and kidney histopathology were detected to assess the GM-induced nephrotoxicity. The oxidative stress(catalase,superoxide dismutase, glutathione and malondialdehyde) was assessed. The inflammatory response(tumor necrosis factor-a, interleukin-6, myeloperoxidase and nuclear factor-kappa B) and apoptotic marker(Bax and Bcl-2) were also evaluated.Results: The results showed that water and 75% ethanol extracts of c. deserticola(named cDW and cDE,respectively)(100, 200 and 400 mg/kg) in combination with GM could recover the reduction of glomerular filtration rate and enhance the renal endogenous antioxidant capability induced by GM. The increase in the expression of renal inflammatory cytokines(tumor necrosis factor-a and interleukin-6), nuclear protein of nuclear factor-kappa B(p65) and the activity of myeloperoxidase induced by GM was significantly decreased upon cDW or cDE treatment. In addition, cDW or cDE treatment could decrease the Bax protein expression and increase the Bcl-2 protein expression in GM-induced nephrotoxicity in rats significantly.conclusion: The study demonstrated that c. deserticola treatment could attenuate kidney dysfunction and structural damage in rats induced by GM through the reduction of inflammation, oxidative stress and apoptosis.

[Objectives]This study aimed to establish a quality evaluation method for Herba cistanche based on the HPLc characteristic chromatograms of the phenylethanoid glycosides and iridoid glycosides,and compare the HPLc characteristic chromatograms of different origins of Herba cistanche.[Methods]The chromatographic conditions used were as follows:column,Agilent ZORBAX Eclipse Plus c18 column(4.6 mm×250 mm,5μm);gradient elution,acetonitrile-0.1%phosphoric acid aqueous solution;flow rate,1.0 mL/min;detection wavelength,240 nm;column temperature,30℃.[Results]cistanche tubulosa(Schenk)Wight showed 9 characteristic peaks,cistanche deserticola y.c.ma showed 10 characteristic peaks,cistanche salsa(c.A.Mey.)G.Beck showed 7 characteristic peaks,and cistanche sinensis G.Beck showed 4 characteristic peaks.Peak 6 was echinacoside,peak 7 was verbascoside,peak 8 was tubuloside A,peak 9 was isoacteoside and peak 10 was cistanoside A.The characteristic chromatograms of the four different origins of Herba cistanche were significantly different.[conclusions]This characteristic chromatogram method has good reproducibility and can be used to distinguish 4 different origins of Herba cistanche,c.deserticola y.c.ma,c.tubulosa(Schenk)Wight,c.sinensis G.Beck and c.salsa(c.A.Mey.)G.Beck.
