ABSTRACT

Objetivos. Determinar el efecto protector del aceite de Helianthus annuus (Girasol) sobre el infarto de miocardio inducido con epinefrina en conejos Nueva Zelanda. Materiales y métodos. Los conejos fueron asignados aleatoriamente en cinco grupos (n= 8 por grupo): blanco, control negativo, experimental 1 (10 mg/kg), experimental 2 (20 mg/kg) y experimental 3 (40 mg/kg). Los grupos experimentales 1, 2 y 3 recibieron aceite de Helianthus annuus durante dos semanas. La epinefrina (2 mg/Kg) se administró a los grupos control negativo, experimentales 1, 2 y 3 durante dos días consecutivos con un intervalo de 24 h después del pretratamiento con aceite. Veinticuatro horas después de la última administración, los conejos fueron anestesiados y sacrificados. Se evaluaron los niveles séricos de troponina I y número de polimorfonucleares por um2. Resultados. Se encontró diferencia significativa entre el grupo control negativo y los grupos experimentales 1, 2 y 3 en los variables niveles séricos de troponina I y número de polimorfonucleares por um2 . Conclusiones: El aceite de Helianthus annuus a dosis de 20 mg/kg tiene efecto protector sobre el infarto de miocardio inducido con epinefrina en conejos Nueva Zelanda.


Objectives. Determine the protective effect of oil Helianthus annuus (Sunflower) on myocardial infarction induced by epinephrine in New Zealand rabbits. Materials and methods. The rabbits were randomized into five groups (8 per group): blank, negative control, experimental 1 (10 mg / kg), experimental 2 (20 mg / kg) and three experimental (40 mg/ kg). Experimental groups 1, 2 and 3 received Helianthus annuus oil for two weeks. Epinephrine (2 mg/Kg) to the negative, Experimental Control 1, 2 and 3 groups was given over two consecutive days with an interval of 24 h after pretreatment with oil. Twenty four hours after the last administration, the rabbits were anesthetized and sacrificed. Serum troponin I and polymorphonuclear evaluated by .mu.m.sup.2. Results. Significant difference between the negative control group and the experimental groups 1, 2 and 3 was found in the serum variables troponin I and polymorphonuclear by .mu.m.sup.2. Conclusions. Helianthus annuus oil at doses of 20 mg/kg has protective effect on myocardial infarction induced by epinephrine in New Zealand rabbits.
