A method is presented for the rapid determination of total mercury in blood. The reagent used is alkaline sodium borohydride, and no digestion of the sample is needed. The detection limit and sensitivity are 1.15 and 1.59 ng of Hg, respectively. The method gives reproducible results (the CV ranged from 5.3 to 6.7% for low and high mercury blood samples, respectively), comparable to those obtain...
this study attempts to investigate the effect of peers’ revision in comparison to that of the teacher, and whether peers’ comments and teachers’ comments facilitate students’ revision? if yes, which one is more effective? also attempts have been made to see which aspects of language are more highlighted by peers versus teachers when commenting. besides, it is investigating the student’s attitud...

In the Brown Norway (BN) rat, mercuric chloride (HgCl(2)) induces a T(h)2-dominated autoimmune syndrome which includes an early phase of mast cell-dependent vasculitis. We have shown in vitro that oxidative stress up-regulates IL-4 in mast cells and predisposes to degranulation. The aim of this study was to determine whether administration of antioxidants inhibits HgCl(2)-induced early vasculit...
THE LOSS OF MERCURY due to volatilization and incomplete removal of oxidizing agents which destroy dithizone are among the major problems in determining mercury in urine. This paper describes a method by which these difficulties are reduced to a minimum. In actual use, this method has been found efficient in screening large numbers of workers exposed to a mercury hazard. Most methods require a ...
