Toxicología de algunos xenobióticos donantes de óxido de nitrógeno, con particular referencia a las azidas
Toxicology of selected nitric oxide-donating xenobiotics, with particular reference to azide [en inglés]
Aunque el óxido de nitrógeno (ON) participa en un gran número de funciones fisiológicas normales, está también implicado en algunos procesos fisiopatológicos. Recientemente, se ha demostrado que toda una serie de sustancias senobióticas deben su actividad biológica in vivo a su transformación biológica en ON. Como aquí se explica, el ON no parece contribuir de manera sensible a la toxicidad de los donadores de ON como los nitritos, la hidroxilamina o el nitroprusiato. No obstante, no se sabe exactamente si el ON generado in vivo a partir de la azida de sodio contribuye de forma importante a su toxicidad. Algunas pruebas existentes atribuyen a la azida una tendencia a inducir una toxicidad acumulativa de baja intensidad. La azida se utiliza ampliamente como agente de conservación en los reactivos acuosos de laboratorio así como propulsor en los almohadones de aire (air bags) que equipan algunos vehículos o que se emplean como toboganes para las evacuaciones de emergencia en los aviones. Para proteger a los trabajadores que manejan estos dispositivos u otros que puedan ponerles en contacto con la azida de sodio, se necesita ampliar el ligero conocimiento de que se dispone sobre la toxicidad de la azida.

Potential industrial carcinogens and mutagens
176 industrial organic chemicals are examined and collated in terms of 21 major groupings and 38 structural subgroupings. Information is given on: synthesis, trace impurities, production volumes, use, occurrence, chemical and biological reactivity, estimated populations at risk, exposure limits in various countries, carcinogenicity and mutagenicity test systems. Combination effects in chemical carcinogenesis, epidemiology, and risk assessment are discussed.
