El objetivo del estudio es determinar la eficacia de la LLLT en la disminución del proceso inflamatorio pulmonar en ratones sépticos. Se utilizaron 32 ratones machos Wistar divididos en cuatro grupos (n=8): control (CG); sepsis 24h (S24); sepsis y tratamiento con LLLT 30 J/cm2 (S24L30); sepsis y tratamiento con LLLT 65 J/cm2 (S24L65). Se realizó la irradiación inmediatamente después de la cirugía en la región anterior de la tráquea y en las regiones ventrales del tórax, bilateralmente, debajo de las costillas. Se realizó un análisis histológico del tejido pulmonar y se cuantificó el número de células inflamatorias. El grupo S24 presentó un aumento de células inflamatorias en comparación al CG (p <0,05); S24L30 aumentó el número de células inflamatorias, mientras S24L65 disminuyó este número en relación al S24 (ambos p <0,05); S24L65 disminuyó el número de células inflamatorias en comparación al S24L30 (p<0,01). Se concluye que la LLLT en dosis específica de energía (30J/cm2) ha sido capaz de disminuir el número de células inflamatorias en el tejido pulmonar en fase aguda de la sepsis.Descargas
