Özet
VPA is widely used in epilepsy and other psychological disorders, increasing the probability of developing non-alcoholic liver diseasein long-term treatments. GLP-2 is a proglucagon belonging to the peptide family expressed in the intestine, pancreas and brain to date.Although there are many studies on the use of GLP-2 for therapeutic purposes on the gastrointestinal system, its effect on liver toxicityis unknown. We aimed to investigate the effect of GLP-2 administration on hepatic function in a rat model with VPA-inducedhepatotoxicity. Rats were injected intraperitoneally at 500 mg/kg and GLP-2 5µg/kg a day. The rats (200-250g) were separated into fourgroups (n=7). Group C was administrated 1 mL of 0.9% SF, Group GLP treated with GLP-2 (5µg/kg/day), Group GLP+VPA werereceived GLP-2 (5µg/kg) 1 h prior to VPA (500 mg/kg), Group VPA received VPA (500 mg/kg), 1 h prior to 1 mL of 0.9% SF ip (n=7).Liver tissues were used to investigate effects of VPA and GLP-2 in the liver 15 days after application. While VPA caused moderate butsignificant liver damage according to biochemical results, mRNA expression of cytokines were found to significantly increase after theday 15. VPA administration significantly induced expression of Interleukin 1 beta (IL-1?), Tumor necrosis factor alpha (TNF-?),Interleukin 10 (IL-10). In contrast, GLP-2 treatment reduced expression of IL-1?, TNF-? and IL-10. Also malondialdehyde (MDA),glutathione s-transferase (?-GST), superoxide dismutase activities (SOD), total antioxidant status (TAS) and total oxidant status (TOS)levels were estimated. GLP-2 had positive effects on both liver enzymes and oxidative stress markers in VPA-induced hepatotoxicity.These results suggest that endogenous GLP-2 administration is associated with a mechanism that moderately protects liver tissue.
