Objectives:
To determine the effects of NAC and erdostein as antioxidant agents on the free oxygen radicals and on their plasma levels. The role of NAC and erdostein on protecting the organ function failure and lung tissue damage due to sepsis was researched.
Methods:
In this study, 40 Sprague-Dawley rats were used. Rats were randomized to four equal groups. Sepsis was performed by the method of Caecum Ligation Perforation (CLP) on rats. Four groups were performed as sham group, sepsis group, sepsis+NAC (20mg/kg/day) and sepsis + erdostein (20mg/kg/day) NAC was given on 0. , 8. and 16.hours after CLP in NAC group. Erdostein was given on 0. and 12.hours after CLP. Blood samples were taken after 24 hours to determine the leukocyte, erythrocyte GSH, leukocyte MPO and plasma MDA levels. In addition, lung tissue samples were taken for histopathological studies and to determine the level of tissue MDA.
Results:
Comparing of groups on the level of leukocyte, leukocyte MPO and lung tissue MDA we determined statistically meaningful results in group 3 according to the group 2. But there were no meaningful differences on erythrocyte GSH and plasma MDA in group3 according to group 2(P>0.05). Comparing of groups on the level of erythrocyte GSH, leukocyte MPO plasma MDA and lung tissue MDA we determined statistically meaningful results in group 4 according to the group 2(P<0.05). But there were no meaningful differences on leukocyte in group 4 according to group 2(P>0.05).
Conclusion:
In this experimental sepsis model; it was determined that low dose NAC and erdostein as antioxidant agents have positive effects on erythrocyte GSH, leukocyte MPO, plasma and tissue MDA levels and the function of lung. Although the treatment with low dose NAC and erdostein has decreased the abnormality of organ function due to sepsis we couldn’t show it histopathologically. We need more experimental studies to determine the effects of NAC and erdostein on sepsis therapy.
