BACKGROUND Conflicting reports about the toxicity of Synedrella nodiflora (L) Gaertn (family Asteraceae), a plant traditionally used in Ghana for the management of epilepsy, abound in literature. The present study evaluates the effect of a 90-day continuous oral administration of a hydro-ethanolic whole plant extract of Synedrella nodiflora (SNE) in male Sprague-Dawley rats. METHODS The toxic...

Selenium (Se) is an essential element for many organisms but also toxic at higher levels. The objective of this study was to identify accessions from the model species Arabidopsis thaliana that differ in Se tolerance and accumulation. Nineteen Arabidopsis accessions were grown from seed on agar medium with or without selenate (50 microM) or selenite (20 microM), followed by analysis of Se toler...

This study was carried out to investigate the preventive effects of galactoglucomannan (GGM), a homogeneous polysaccharide from Dendrobium huoshanense, on liver injury and fibrosis induced by sodium selenite. Sprague-Dawley rats injected subcutaneously with sodium selenite at the dosage of 3.28 mgkg(-1) b.wt. were set as the model groups. Rats treated with sodium selenite at the dosage of 3.28 ...

This work investigates the potential of Rubus ulmifolius, indigenous to a metal contaminated site--Esteiro de Estarreja--for phytoremediation purposes. The site has a long history of metal contamination. The accumulation of lead (Pb), arsenic (As) and nickel (Ni) in different sections--roots, stems and leaves - of the plant was assessed and compared to the levels of those metals in the soil and...

Trace elements play a significant role in biological processes. The aim of this study was to evaluate the trace elements of interest in kidney disease in commonly consumed greenhouse vegetables in Isfahan, Iran. Six kinds of greenhouse vegetables namely; Raphanus sativus (Radish), Cucumis sativus (Cucamber), Solanum lycopersicum (Tomato), green Capsicum annuum (Green bell pepper), yellow Capsic...

The aim of the study was to identify trends and dynamics changes in chemical biochemical properties soil induced by rotational grazing farmed deer. Soils pH content mineral nitrogen forms, total nitrogen, organic carbon were determined activity three enzymes. monitored soils slightly acidic neutral, with 1 mol KCldm−3 ranging from 6.37 7.03. contents carbon, range 9.42–19.37 gkg−1 1.13–2.24 gkg...

In traditional medicinal system different parts of the plant have been mentioned to be useful in a variety of diseases. The plant material is widely used as a purgative, remedy for diarrhoea and cure for itch. ...

Turpun besin maddesi ihtiyacının karşılanması ve yüksek kalitede ürün alınmasında kükürt(S) önemli bir yer tutmaktadır. Biyokömür uygulamaları toprak kalitesini bitki gelişimini olumlu etkilemektedir. Çalışma; tarım potansiyeline sahip olan İç Anadolu’da alan Konya kireçli topraklarında yetiştirilen turp bitkisinin kükürtlü gübre isteğinin belirlenmesi amacıyla yürütülmüştür. Çalışmada biyokömü...

Sleep spindles and spike-wave discharges are thought to originate from the same thalamic pacemaker. In the present work it is investigated whether sleep spindles and spike-wave discharges are also sensitive for the same drugs. Adult male WAGIRij rats were chronically implanted with frontal and occipital EEG electrode pairs. Rats were intraperitoneally injected with clonidine (0.00625 mgkg), phe...

Solanum nigrum was found to proliferate in sediments with high levels of metal pollution. The effect of Zn on plant growth and tissue metal accumulation was assessed. The response of the plant to the inoculation with four different isolates of arbuscular mycorrhizal fungi (AMF) (Glomus sp. BEG140, Glomus claroideum, Glomus mosseae and Glomus intraradices) was studied. While the isolates of AMF ...
