Hazards of hydrogen peroxide.
Hydrogen peroxide solution is commonly used for irrigating and cleaning wounds. It has some germicidal properties and may remove contaminants mechanically. When it is applied to tissues catalase causes its rapid molecular decomposition with the release of oxygen bubbles (1 ml of hydrogen peroxide 3% (10 vol) will release 10 ml oxygen).' Irrigation under pressure or into enclosed body cavities, ...
متن کاملGreen synthesis of nano polypyrrole using urea-hydrogen peroxide
Polypyrrole is one of the most useful conductive polymers, but green synthesis of this polymer has been restricted until now. The objective of the present paper is green synthesis of nano polypyrrole (PPy) by oxidative polymerization using urea-hydrogen peroxide. It was found that conductivity and morphology of polypyrrole are highly dependent on the reaction conditions such as the molar ratio ...
متن کاملHydrogen Peroxide in Adaptation
The perception of the roles of H 2 O 2 in living systems has come a long way, transcending from H 2 O 2 being considered as (i) exclusively damaging; (ii) a necessary evil " unwanted but an inevitable product of aerobic metabolism " ; (iii) important for specific biological processes that involve ROS aggressiveness, such as the battle of the innate immune system with pathogens; and (iv) signall...
متن کاملHydrogen Peroxide in Cholera
Sir,?I read a note from the pen of Dr. N. C. Moitra, m.b., in the Indian Medical Gazettte, October number, on the use of hydrogen peroxide in cholera, in which he says that he wrote a short note in the Therapeutic Notes published by Parke, Davis and Co., but he gives no date as to when he had written this short note. Also he does not say as to whether he uses liqr. hydrogen peroxide B. P. (10 p...
متن کاملMembrane transport of hydrogen peroxide.
Hydrogen peroxide (H2O2) belongs to the reactive oxygen species (ROS), known as oxidants that can react with various cellular targets thereby causing cell damage or even cell death. On the other hand, recent work has demonstrated that H2O2 also functions as a signalling molecule controlling different essential processes in plants and mammals. Because of these opposing functions the cellular lev...
