In the study, it was aimed to research the effects of an endogenous neuropeptide called cortistatin (CST) which is isolated from the brain on parameters of antioxidant system and cytokine levels of rabbits with turpentine oil induced acute inflammation. In the study using 28 healthy, male rabbits from New Zealand breed, animals were randomly divided into four groups consisting of control (C), turpentine (T), cortistatin (250 µg/kg) (CST), and turpentine + cortistatin (250 µg/kg) (T+CST). Reduced glutathione (GSH), super oxide dismutase (SOD, malondialdehyde (MDA) levels belonging to antioxidant and oxidant systems, interleukin-6 (IL-6) and tumor necrosis factor -α (TNF-α) levels from inflammatory cytokines were studied in the blood samples taken after 2 and 6 hours and while cortistatin administration significantly contributed for maintaining GSH at protective level in T+CST group (p<0.05), it caused a change which was not statistically significant with respect to MDA and SOD levels increasing based on elevated lipid peroxidation levels in the tissue along with the inflammation (p>0.05). Depending on resulting data of the study, it was concluded that despite there were effects observed regarding that cortistatin plays an inflammation suppressing role, this was smaller than the effect observed in conditions such as endotoxemia and sepsis because design of study did not lasted for long.
