HISTORIC[1] Halogenated compounds have been employed as fire extinguishing agents since the early 1900s, when handheld extinguishers containing carbon tetrachloride (CCl4) were first introduced. In the late 1920s, methyl bromide (CH3Br) was found to be more effective than carbon tetrachloride, and was widely used as a fire extinguishing agent by the British in the late 1930s for aircraft protec...

The nucleation site density (N/A) during pool boiling of binary mixtures has been experimentally examined in terms of the heating surface physical properties, the liquid physical properties, the vapour liquid equilibria and the surface micro-roughness. The liquid mixtures used were acetone carbon tetrachloride and n-hexane carbon tetrachloride. A parameter R,, to characterize the micro-roughnes...

Plant systems can be effective pump-and-treat systems for some contaminants. There is interest in finding inexpensive remediation technologies for sites contaminated by carbon tetrachloride and ethylene dibromide from grain fumigation activities. Experimental investigations have shown that volatile compounds such as trichloroethylene and methyl tertiary butyl ether (MTBE) are released to the at...

Curcumin and its analogue (bisdemethoxy curcumin analogue [BDMC-A]) were studied for their possible lipid-lowering properties in carbon tetrachloride (CCl4)induced hepatotoxicity in rats. Carbon tetrachloride (3ml kg 1 wk ) administration to albino Wistar rats increased the levels of hepatic marker enzymes such as aspartate transaminase (AST), alkaline phosphatase (ALP), and c-glutamyl transfer...

Aphanamixis polystachya is a traditional medicinal plant of the Meliaceae family in India. A crude ethanolic extract of the leaf of this plant shows a beneficial effect on toxic liver injury. Its antihepatotoxic activity was evaluated on carbon tetrachloride (CCl4)-induced liver injury in a rat model. The assessment of hepatoprotective activity was evaluated by measuring the activities of aspar...

Abstract: Radiation and chemicals were the major clinical toxicants known to cause cellular damage during prognostic interventions in vivo. Cellular molecular damages liver causes for hepatocellular injury due various toxicities. Though many antioxidants alleviate types of hepatotoxicities, protection exerted by combination N-acetyl cysteine (NA) Thymoquinone (TQ) combined toxicities radiation ...
