Accumulation of zinc, cadmium, and lead in four populations of Sedum alfredii growing on lead/zinc mine spoils.
Sedum alfredii Hance is a newly reported zinc (Zn) and cadmium (Cd) hyperaccumulator native to China. In this study, four populations of S. alfredii were collected from Yejiwei (YJW), Jinchuantang (JCT) and Qiaokou (QK) lead (Pb)/Zn mines located in Hunan Province as well as Quzhou (QZ) Pb/Zn mine located in Zhejiang Province for exploring the intraspecies difference of this plant in metal accu...
متن کاملNiacin Exacerbates Methyl Prednisolone-Induced Bone Changes in Growing Rats
Positive role of niacin on serum lipid profile of rats treated with glucocorticoids (GCs) has been reported. This study aims to evaluate effect of niacin on bone changes in GC-induced dyslipidemic rats. A number of 28 growing rats divided into four groups and treated as control, Methyl prednisolone (MP) group (3.5 mg/kg five days a week, SC); MPN group (MP + niacin 200 mg/kg/day orally) and MPA...
متن کاملGrowth and metal accumulation in vetiver and two Sesbania species on lead/zinc mine tailings.
The lead (Pb)/zinc (Zn) tailings contained high concentrations of heavy metals (total Pb, Zn, Cu and Cd concentrations 4164, 4377, 35 and 32 mg kg(-1), respectively), and low contents of major nutrient elements (N, P, and K) and organic matter. A field trial was conducted to compare growth performance, metal accumulation of Vetiver (Vetiveria zizanioides) and two legume species (Sesbania rostra...
متن کاملDifferential expression of Lead accumulation during two growing seasons by desert shrub Acacia victoriae L.
In desert reclamation strainer plants can be used for improvement and decrease pollution of soil and water. This technology can be used to remove both inorganic and organic contaminants in soil. In this study, one year old Acacia victoriae seedlings were exposed to Pb (NO3)2 in 5 different concentrations; 0, 50, 250, 500 and 1000 mg Pb L-1 for 45 days in two growing seasons. Subsequently, the h...
متن کاملMarginal zinc deficiency exacerbates experimental colitis induced by dextran sulfate sodium in rats.
We investigated the impact of Zn status on the maintenance of mucosal homeostasis. Rats were fed diets containing different amounts of Zn (30, 10, 5, <1 mg Zn/kg diet) for 21 d. Serum Zn concentrations were lower in rats fed marginally Zn-deficient (MZD; 5 mg Zn/kg diet) and severely Zn-deficient (<1 mg/kg) diets but not in those fed the marginally Zn-adequate diet (10 mg/kg) or the Zn-adequate...
