Radium analysis is carried out by batch adsorption from natural waters on basic lead rhodizonate supported on charcoal, LERHO, starting from 2-L samples. 133Ba is added to allow the measurement of the overall chemical yield by gamma counting. Radium is
The metal distribution within mycorrhizal and nonmycorrhizal roots of Epipactis atrorubens collected from zinc mine tailings and an area rich in heavy metal ores (both located in southern Poland) was investigated. The tailings, consisting of post-flotation material, were characterised by
The histochemistry of barium was investigated with particular reference to the use of sodium rhodizonate. It was found that not all batches of sodium rhodizonate were able to effect satisfactory visualisation of barium deposits. None of the other histological parameters

Very little literature exists on gunshot wounds on decomposed material. In this study, seven pig heads underwent a shooting test. Entrance wounds from the first head underwent neutron activation analysis (NAA) and histological testing immediately after the firing test; the

A rapid abrasion test (RAT) was developed for screening ceramicware for Pb. A Pb-sensitive chromogen (rhodizonic acid) reacts to form a persistent colored complex, indicating the presence of Pb. RAT takes 2-5 min to complete; a positive test is easily
A colloid titration technique has been used to determine the sulfate and carboxylate content of various glycosaminoglycans and has been validated by comparing the results with data obtained using well-established techniques. The method has been applied to the measurement of

It is important to investigate the clothing, as well as the body, to determine the range of fire of entry wounds in firearm injuries. Clothing can affect the amount of gunshot residues (GSR) reaching the body and their distribution. The

The histological staining technique using rhodizonate is also effective for the determination of the firing distance by examining the distribution and intensity of the staining reaction. The differentiation between absolute close-range shots and long-range shots is generally possible without any
This study deals with the impact of chronic exposure to lead on male and female fertility in rats. Male and female rats (3 months old) were fed on commercial tablets (SICO, Sfax). For drinking, some rats were given distilled water

A spectrophotometric determination of sulfate ion and its application in studies of substrate purity and of aryl sulfatase A kinetics.
Barium ions precipitate inorganic as well as organic sulfate compounds and they can be detected by a reaction with sodium rhodizonate. In this work, we describe the use of a barium method for the selective demonstration of sulfated glycosaminoglycans in

We report a staining method for cadaveric tissue using sodium rhodizonate as a skin marker for gunshot residues and a counterstain for the surrounding connective tissue. We studied six well preserved subjects who had died of close range gunshot injury.

Rhodizonic acid, a six-membered cyclic hydroxyquinone, produced reactive oxygen species as a complex with transition metals. Addition of rhodizonic acid with ferrous ion caused an inactivation of aconitase the most sensitive enzyme to oxidative stress in permeabilized yeast cells. The

In this study, we applied a microscopic quantitative method based on the use of sodium rhodizonate to verify the presence of residues and their distribution on the cutis of gunshot wounds. A total of 250 skin samples were selected from
[Influences of oral hypoglycemic agents on the beta-cell of the rabbit pancreas].
In this work we investigated the toxicity of a polyphenolic p-benzoquinone derivative, the tetrahydroxy-1,4-quinone (THQ) toward V79 Chinese hamster fibroblasts and analyzed the role of H2O2 and Ca2+ in that mechanism. The exposure of exponentially growing cultures to THQ, in
