Plasma iron turnover has been evaluated in the growing rat. Consistent data were obtained with the intravenous injection of radioiron in the form of ferrous sulfate or ferric citrate. Plasma iron turnover changed as a function of plasma iron concentration. Only part of this effect in the rat was due to the different rates of clearance of mono-and differic transferrin, the latter having a higher...

PURPOSE The purpose of this study was to compare the effectiveness of 5% sodium hypochlorite (NaOCl) to that of ferric sulfate (FeSO4) as a pulpotomy medicament in decayed primary molars. METHODS Healthy subjects between 4 and 9 years with at least 2 primary molars needing pulpotomy consented to receive either NaOCl or FeSO4 and restoration with IRM base/stainless steel crown in a prospective...

Heating mixtures of sodium nitrite, cysteine, and either ferrous sulfate or ferric chloride at 121 C for 20 min at pH 6.5 or 6.3 produced a potent inhibitor of Clostridium perfringens vegetative cells and spores when added to previously heat-sterilized fluid thioglycolate medium. When the mixtures containing FeSO4 at pH 5.2 or FeCl3 at pH 2.7 were heated, the inhibitory effect was not produced....

Wastewater management in two companies representing the pharmaceutical industry was investigated and implemented. The results showed that the integration of the pollution prevention approach followed by an equalization tank reduced the organic load up to 70%, while further chemical treatment using either alum or ferric chloride aided with lime produced a quality of effluent suitable for restric...

The analysis of pediatric serum for total cholesterol in the presence of high amounts of bilirubin presents special problems. The serum specimens are so small that a direct microor ultramicromethod has to be used, and consequently the error owing to bilirubin is impressive. In the proposed method, cholesterol is precipitated, along with other serum lipids, from only 20 .iliters of serum as a de...

Ammonium was shown to be a limiting nutrient for iron oxidation in cultures of Thiobacillus ferrooxidans. In addition, one strain was also able to assimilate nitrate, but not nitrite, for growth and coupled iron oxidation. Some amino acids (0.5 mM) were tested as a source of nitrogen; none clearly stimulated bacterial activity and inhibition was commonly encountered. Complex nitrogenous compoun...

This study evaluated in vitro the influence of a temporary filling {zinc oxide-eugenol (ZOE)} and two pulpotomy agents {formocresol (FC) and ferric sulfate (FS)} on shear bond strength (SBS) of two dentin adhesives to the dentin of primary molars. A total of 80 dentin surfaces were prepared and randomly allocated into 10 groups of 8 specimens each. Groups were subjected to different treatments,...

PURPOSE: To provide further quantitative studies concerning the relationship with age between regional brain iron and T2 shortening. METHODS: a) Quantitative T2 calculations of eight anatomic regions (red nucleus, substantia nigra, dentate nucleus, corpus callosum, caudate, putamen, temporal lobe white matter, and frontal lobe white matter) from T2-weighted spin-echo images were performed in 60...

Iron is a ubiquitous constituent of cytochromes, oxygen-binding molecules and a variety of enzymes because of its property to transition from ferric (Fe3+) to ferrous (Fe2+) state, leading to change in the redox potential. However, the same property accounts for free radical injury. In order to overcome harmful effects of iron we investigated the possible protective effect of quercetin (QCT), a...
