Abstract

This study was aimed to investigate the possible protective effects of different amount of olive leaf extracts and infusion on some biochemical and haematological parameters of streptozocin-induced experimental diabetic rats. For this purpose, 56 Wistar albino rats were randomly divided into 7 groups (n=8). Biochemical and haematological analyses were performed at the end of the 21-day trial. It was observed that HGB, HCT, MCV were positively affected (p<0,05), while RBCs were not statistically significant affected in all OLE-applied groups. In diabetes+OLE50 and OLE-100 groups, WBCs significantly decreased compared to the that of control group (p<0,05), while statistically significant change was not observed in the OLE-25 group. The cholesterol values of the diabetes+OLE25 group were significantly lower than those of the control group (p<0,05), while the increase in the diabetes+OLE100 group was significant at the statistical level (p<0,05). The increase in diabetes+OLE-50 group was not significant. In the diabetes+OLE-25, diabetes+OLE-50 and diabetes+OLE-100 groups, triglyceride decreased significantly (p <0,05) in comparison to diabetic group. In the infused diabetic group, RBC, HGB, HCT, MCV, MPV, PDW and EOS were significantly increased in the positive direction (p <0,05). Infusion was found to have negative effect on triglyceride; LDL, Cl, Na. HDL, Mg and P were found to be affected positively. It was determined that the most effective dose on cholesterol and triglycerides in OLE-administered groups is OLE-25 mg/kg. Infusion was found to have positive effect on HDL, while LDL was affected negatively. On the other hand, the decrease in cholesterol was found to be not statistically significant, while the decrease in triglyceride was significant.

Özet

Bu çalışma, değişik oranlardaki zeytin yaprağı ekstraktının (Olive Leaf Extract-OLE) ve infüzyonunun streptozosin ile oluşturulmuş deneysel diyabetik sıçanların bazı biyokimyasal ve hematolojik parametreleri üzerine olası koruyucu etkisini araştırmak amacıyla planlanmıştır. Bu amaç doğrultusunda, 56 adet Wistar albino sıçan rastgele 7 gruba ayrıldı (n=8). 21 günlük deneme sonunda biyokimyasal ve hematolojik analizleri yapıldı. OLE uygulanan grupların hepsinde RBC’ler istatiksel anlamda etkilenmezken, HBG, HCT, MCV’nin pozitif yönde etkilendiği görüldü (p<0,05). Diyabet+OLE-50 ve OLE-100 gruplarında WBC’ler, kontrol grubuna göre, anlamlı şekilde gerilerken (p<0,05), OLE-25 grubunda değişim gözlenmedi. Diyabet+OLE-25 grubunun kolesterol değerlerinde, kontrol grubuna göre, anlamlı bir düşüş gözlenirken (p<0,05), diyabet+OLE-100 grubundaki artış istatiksel düzeyde önemliydi (p<0,05). Diyabet+OLE-50 grubundaki artış anlamlı değildi. Diyabet+OLE-25, diyabet+OLE-50 ve diyabet+OLE-100 gruplarında, trigliserid diyabet grubuna göre anlamlı derecede düşmüştü (p<0,05). İnfüzyon uygulanan diyabetli grupta RBC, HGB, HCT, MCV, MPV, PDW ve EOS pozitif yönde anlamlı şekilde artmıştı (p<0,05). İnfüzyon trigliserid, LDL, Cl ve Na’u negatif yönde, HDL, Mg ve P’u pozitif yönde etkilediği belirlendi. OLE uygulanan gruplar içerisinde kolesterol ve trigliserid üzerine en etkili dozun OLE-25 mg/kg olduğu gözlendi. İnfüzyonun ise, HDL’yi pozitif yönde, LDL’yi de negatif yönde anlamlı şekilde etkilediği görüldü. Aynı şekilde kolesteroldeki düşüşün istatistiksel olarak önemsiz, trigliseritdeki düşüşün ise istatistiksel olarak önemli olduğu yönünde bulgular elde edildi.
