AIM The main objective of the study was to determine the deleterious effect of fluoride on plasma trace minerals of fluorotic cattle and to evaluate the effect of Tamarindus indica leaf powder toward correction of the same. MATERIALS AND METHODS A total of 30 cattle exhibiting chronic sign of fluorosis and 10 healthy cattle from nonfluorotic area were incorporated in this study. Fluorotic cat...

generally heavy metals exist in all soils, but soil pollution is rising by time due to human activities. soils in the proximity of mines are more pruning to pollution of heavy metals due to mine exploring and excavation. this research was carried out to evaluate the soil pollution of sepahanshahr suburb with pb, zn and cd. during a field work campaign 100 soil samples were selected randomly fro...

Two sensitive wavelength (SW) selection methods combined with visible/near infrared (Vis/NIR) spectroscopy were investigated to determine the levels of some trace elements (Fe, Zn) in rice leaf. A total of 90 samples were prepared for the calibration (n = 70) and validation (n = 20) sets. Calibration models using SWs selected by LVA and ICA were developed and nonlinear regression of a least squ...

This study compared the effects of varying lipid content and dietary concentration of a lipid-encapsulated (LE) ZnO product to those of native ZnO and thereby to find insights into optimal lipid coating and dosage of the Zn supplement. A total of 192 21-d-old weanling pigs were allotted to 48 pens, after which each six pens received a ZnO-free basal diet supplemented with 125 ppm ZnO (100 ppm Z...

In order to get the information on the force-distance curve for the interaction between a dislocation and a solute atom, amplitude-dependent interna1 friction was measured at 1.7 30 K on Al-100 at ppm Zn and Al-50 at ppm Zn single crystals. The temperature dependence of applied strain under a constant decrement is the same for two concentrations with high accuracy. The data were analyzed by the...

When carp (Cyprinus carpio) were exposed to 5 and 30 ppm Cd in the water, the contents of Cd-binding protein, which has low molecular weight, increased in the hepatopancreas, kidney, gills and gastrointestinal tract with the duration of exposure. This Cd-binding protein was purified from hepatopancreas, kidney, gills, and spleen of carp administered 2 mg/kg Cd (as CdCl2), intraperitoneally for ...

Zinc (Zn) is an essential nutrient that affects immune function, especially within the digestive system, although the underlying mechanisms are not well understood. This study examined the effects of short-term moderate Zn restriction on intestinal health and immune function in lipopolysaccharide (LPS)-challenged mice through plasma cytokine profiling and histological evaluation of intestinal t...

Levels of Zn, Cu, Cd, As, and Pb in the kidney, Liver, Gills and Heart of African cat fish (Clarias gariepinus) from the Ogun River in Ogun State located close to six major industries in the South Western part of Nigeria, were determined using Bulk Scientific Atomic Absorption Spectrophotometer. Fishes were also collected from Government owned fish farm in Agodi, Ibadan which was considered a r...

The present study estimated the concentration (in ppm) of heavy metals Zn, Fe, Cu and Pb in water samples edible tissue Labeo boga; both collected from non polluted (Station I) II) locations river Tawi, Jammu, India. mean (Zn, Cu, Pb) at Station I were 0.048±0.008 (ppm); 0.016±0.001 0.157±0.002 (ppm) 0.0001±0.0001 respectively; while II, these values 0.133±0.001 0.022±0.002 0.206±0.002 0.002±0....

Kandungan logam berat pada sedimen sungai Batang Agam segmen Kota Bukittinggi telah diidentifikasi. Sampel diambil aliran sepanjang 3 km 6 titik sampel. Enam sampel yang kemudian di uji XRF untuk mengetahui kandungan beratnya. Hasil menunjukan bahwa mengandung Cr, Mn, Fe, Ni, Zn, Cu, As dan Pb. Konsentrasi rata-rata Sungai sudah melebihi ambang batas tetapkan, yaitu Cr (206,6 ppm), Mn (3646,6 F...
