Abstract
Bu çalışmada, deneysel diyabet oluşturulmuş ratlarda, likopen uygulamasının serum neopterin, CRP, MPO ve GGT aktivitesini araştırmak amaçlanmıştır. Çalışmada 250-300 gr ağırlığında ve 7-8 haftalık erkek WistarAlbino ratlar kullanılmıştır. Ratlar rastgele seçilerek her bir grupta 7 rat olacak şekilde, kontrol, likopen, diyabet ve DL grupları olmak üzere dört grubu ayrıldılar. Deneysel diyabet oluşturmak için 45 mg/kg düzeyinde soğuk sitrat tamponunda çözdürülmüş streptozotosin (STZ) intraperitoneal yolla uygulandı. Likopen ise mısır özü yağında çözdürülerek 10 mg/kg/gün olarak likopen ve DL gruplarına gavaj ile agız yoluyla uygulandı. 28 günlük deneme süresinin sonunda anaztezi altında ratların kalplerinden serum tüplerine kan örnekleri alındı. Kan örnekleri santrüfüj edilerek serumları elde edildi. Serum örneklerinden, neopterin, CRP, MPO ve GGT aktiviteleri tayin edildi. Analiz sonuçlarına göre, en düşük neopterin seviyesi kontrol grubunda elde edildi (p<0.001). En yüksek neopterin seviyesi diyabet grubunda elde edildi, likopen grubu neopterin seviyesi diyabet grubundan düşüktü, fakat istatistik olarak bir fark tespit edilmedi, DL grubu neopterin seviyesi diyabet ve likopen gruplarından düşük tespit edildi ve bu düşüklük istatistik olarak analamlıydı (p<0.001). MPO değeri diyabet grubunda diğer gruplara oranla en düşük gözlendi (p<0.001). Kontrol grubu MPO değeri, likopen ve DL grubuda göre istatistik olarak yüksek tespit edildi (p<0.001). CRP seviyesi bakımından bütün gruplar arasında istatistik bir fark gözlenmedi. GGT aktivitesi gruplar arası karşılaştırmada en yüksek olan grup diyabet grubuydu ve en düşük olan GGT aktivitesi DL grubunda gözlendi (p<0.001). Sonuç olarak, inflamasyon markırı olan neopterin ve GGT likopen verilen gruplarda düşük olduğu bulundu ve. Bu bulgular, likopenin diyabetin komplikasyonları ve buna bağlı inflamasyonun önlenmesinde yararlı olabileceği sonucuna varıldı.Anahtar sözcükler: Diabetes Mellitus, Rat, Likopen, Neopterin, MPO, GGT, CRP50
This study was planned to determine the effects of lycopene treatment on serum neopterin, CRP, MPO and GGT activities of experimental diabetics rats. For this purpose, 7-8 weeks of 28 male Wistar-Albino rats weighing 250-300 g have been used. The subjects have been randomly divided into four groups as each of them consisting of seven rats; control group (C), diabetic group (D) without lycopene, diabetic group with lycopene (DL) and the group which is given only lycopene (L). In order to create the diabetes in rats in group D and DL groups 45 mg/kg single dose streptozotocin (STZ) was administered intraperitoneally (i.p). After disolving in sunflower oil 10 mg of lycopene kg/day was administered to rats in group L and DL. After the 28 days trial process, blood has drawn from the heart of animals under anesthesia. HbA1c, Neopterin, MPO, CRP and GGT activities were analysed from obtained serum samples. It was observed that the lowest neopterin levels in control group (p<0.001). The higher neopterin levels were obtained in the diabetes group. Neopterin level in the lycopene group was lower than diabetes group but was not statistically deifferent. Neopterin level in the DL group was lower than D group and L group and was statistically different (p<0.001). MPO levels in the D group was observed the lowest than in the other groups (p<0.001). MPOlevel in the control group was higher statistically than L and DL groups. CRP level was not statistically significant in all groups. Comparision between the groups was highest group the group of D (p<0.001) and the lowest GGT activity was obtained in the DL group. In conclusion, neopterin, and GGT as inflamation marker, were decreased in lycopene treated groups. These data may indicate that lycopene has antiinflamatuar effects to prevent againts of diabetic complications.Key Words: Diabetes Mellitus, Rat, Lycopene, Neopterin, MPO, GGT, CRP.
