MONTERO GONZALEZ, Teresita et al. Oxidative stress in a model of burnt mouse treated with Aloe b, ozone and epidermal growth factor. Rev Cub Med Mil [online]. 2006, vol.35, n.3, pp. 0-0. ISSN 1561-3046.

Burn disease stimulates systemic inflammatory response and its morphologic expression that is multiple organ failure. With the objective of identifying the behaviour of oxidative stress through malonaldehyde, superoxide dismutase, and catalase, and its change by using the systemic treatment based on Aloe b, ozone or epidermal growth factor, a dry burn model of a 11 % area in balb/c female mice of 20 ± 2 g (n= 24) was designed. Eutanasia was applied at different moments, organs were studied with qualitative evaluation of intensity degrees, and biochemical variables were analyzed from the kidney and the liver of mice. Test G served to find out dependence among variables and Test t was used to compare percentages. Bifactoral variance analysis and Duncan´s multiple range test were used in the studied oxidative stress variables. Ethical standards on work with animals were complied with. Dependence was observed among the various groups and survival rate (G= 268,83***) was higher in the treated groups. Untreated groups showed more intensive multiple organ damage and worse oxidative stress response. The groups treated with ozone and epidermal growth factor showed better recovery. The treatment with ozone and epidermal growth factor immediately after burning favored recovery and survival of balb/c mice.

Keywords : Organ multiple damage; experimental model of burned mouse; oxidative stress; ozone; Aloe b; epidermal growth factor.
