ABSTRACT

PURPOSE:

To evaluate the effects of iloprost a prostacyclin analogue on the hepatic IR injury in rats.

METHODS:

Forty male Sprague-Dawley rats (250-300 g) were divided into four groups each containing 10 rats;(1)- controls data from unmanipulated animals; (2) sham group rats subjected to the surgical procedure, except for liver I/R, and given saline; (3) I/R group rats that underwent liver ischemia for 45 min followed by reperfusion for 45 min; (4) IR/ Iloprost group rats pretreated with iloprost (10 µg kg-1, i.v). Liver tissues were taken to determine SOD, CAT, GSH, and MDA levels and for biochemical and histological evaluation.

RESULTS:

The plasma ALT and AST levels were increased in group 3 than in group 4. MDA values and the liver injury score decreased, while the SOD, CAT, and GSH values increased in group 4 compared to group 3. In group 3, hepatocytes were swollen with marked vacuolization. In group 4, there were regular sinusoidal structures with normal morphology without any signs of congestion.

CONCLUSION:

We demonstrated hepatoprotective effects of iloprost against severe ischemia and reperfusion injury in rat liver.
RESUMO

OBJETIVO:

Avaliar os efeitos do iloprost, um análogo da prostaciclina nos danos causados ao fígado de ratos pela lesão de IR.

MÉTODOS:

Quarenta ratos machos Sprague-Dawley (250-300 g) foram distribuídos em quatro grupos de dez; - (1) grupo de controle dados de animais não manipulados; (2) grupo "sham" ratos que sofreram intervenção cirúrgica sem I/R, aos quais foram administrados solução salina; (3) grupo I/R; animais que foram submetidos à isquemia por 45 minutos seguida de reperfusão por 45 minutos; (4) grupo I R/Iloprost ratos previamente tratados com Iloprost ( 10µ kg-1, i.v). Tecidos hepáticos foram retirados para determinar os níveis de SOD, CAT, GSH, e MDA e para avaliação bioquímica e histológica.

RESULTADOS:

Os níveis de plasma ALT e AST aumentaram no grupo 3 mais do que no grupo 4. Os valores de MDA e o índice de lesões hepáticas diminuíram, enquanto os valores de SOD, CAT e GSH aumentaram no grupo 4, em comparação com o grupo3. No grupo 3, os hepatócitos se apresentaram edemaciados, e vacuolizados. No grupo 4, havia estruturas sinusoidais regulares, apresentando morfologia normal, sem sinais de congestão.

CONCLUSÃO:

Demonstramos os efeitos hepato-protetores do Iloprost contra a isquemia grave e o dano de reperfusão no fígado de ratos.
