Purpose: To investigate the effect of Flueggea leucopyrus Wild aqueous extract (FLAE) on the urinary output of rats. Method: Three different doses of FLAE (500, 1000 and 1500 mgkg), furosemide (13 mg kg as diuretic reference) and distilled water (as control) were orally administered to healthy adult hydrated rats. Cumulative urine output was monitored hourly over 6 h. Selected urinary parameter...

Patients were randomly allocated to one of two groups; intravenous or epidural analgesia, with twenty patients in each group. General anesthesia was induced with thiopentone 5-6 mgkg-1 and maintained with 0.8-1.0% isoflurane and 66% nitrous oxide in 33% O2. The trachea was intubated after administration of vecuronium 0.1 mgkg-1. Patients in the epidural analgesia groups then received, by random...

In India, agricultural soil has been deteriorated by various on-going practices involving application of chemical fertilizers, pesticides and effluents. Presently, Amritsar (Punjab), an agricultural land, is undergoing rigorous cultivation of wheat and rice crops which consequently increased the application of chemical pesticides and fertilizers for high yield. These agricultural practices are ...

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...

Biological uranium reduction was investigated using bacteria isolated from a uranium mine in Limpopo, South Africa. Background uranium concentration in soil from the mine was determined to be 168 mgkg(-1) much higher than the typical background uranium concentration in natural soils (0.30-11.7 mgkg(-1)). Therefore it was expected that the bacteria isolated from the site were resistant to U(VI) ...
