AIMS/INTRODUCTION The present study was designed to evaluate the effect of chromium malate on glycometabolism, glycometabolism-related enzyme levels and lipid metabolism in type 2 diabetic rats, and dose-response and curative effects. MATERIALS AND METHODS The model of type 2 diabetes rats was developed, and daily treatment with chromium malate was given for 4 weeks. A rat enzyme-linked immun...

Chromium(VI) compounds are known to be potent toxic and carcinogenic agents. Because chromium(VI) is easily taken up by cells and is subsequently reduced to chromium(III), the formation of paramagnetic chromium such as chromium(V) and chromium(III) is believed to play a role in the adverse biological effects of chromium(VI) compounds. The present report, uses electron spin resonance (ESR) spect...

1. Chromium sesquioxide (Cr2O3; 1.5 g/day) and [51Cr]chromic chloride [51CrCl3 (0.3 muCi/day)] were compared as continuously administered non-absorbed markers for the correction of faecal recoveries in 14 calcium balance studies each lasting at least 18 days. 2. The mean recoveries of each, 98.4% for Cr2O3 and 101.9% for 51CrCl3, were not significantly different from 100%. 3. The two markers re...

The carcinogenicity of chromium compounds is reviewed with specific attention to the gaps in knowledge for risk estimation and research needs. The most important problems at present are whether trivalent chromium compounds cause cancer, and whether there is a difference in cancer causing effects between the soluble and the slightly soluble hexavalent compounds in the practical exposure situatio...

As conventional physico-chemical heavy-metal remediation technologies like ion-exchange, reverse osmosis, electrodialysis etc. are becoming extremely expensive, the possibility of use of microorganisms in bioremediation or biorecovery of different heavy metals from industrial effluents is extensively explored by different workers. Hexavalent chromium stressed environmental fungal isolates from ...

hen the first trivalent chromium electroplating process was commercially introduced in the mid-l970s, information on the corrosion properties of the deposits and other physical properties was unknown. To obtain a comprehensive understanding about the corrosion properties of trivalent chromium electrodeposits over a variety of nickel deposits, chromium deposits from trivalent chromium electrolyt...

he strict corrosion-control requirements in the aerospace inT dustry were developed based on the performance of hexavalent chromium (chromates). With the recent rash of environmental regulations targeting hexavalent chromium, it is reasonable to ask what the industry’s response has been to identify acceptable replacement technologies. Does the aerospace industry take the “ostrich response,” whi...
