Özet
Bu çalışmada, Wistar albino türü sıçanlara nitrik oksit (NO) inhibitörü olan L-NAME (N-nitro-L-arginin-metil ester) uygulanarak oluşturulan oksidatif stresin giderilmesinde, propolisin koruyucu rolünü tespit etmek amacıyla, böbrek ve kalp dokularında bazı biyokimyasal analizler yapılmıştır.Çalışmada deney hayvanları; kontrol, propolis, L-NAME ve L-NAME +propolis olmak üzere dört gruba ayrılmıştır.Sıçan böbrek dokularında; L-NAME uygulama grubunda katalaz (CAT) aktivitesi ve malondialdehit (MDA) düzeyinde, kontrol grubuna göre anlamlı artışlar belirlenirken, NO düzeyinde önemli azalma meydana geldi (P?0.001). L-NAME + propolis grubunda ise L-NAME grubu ile karşılaştırıldığında CAT aktivitesi ve MDA miktarında anlamlı azalmalar meydana gelirken, NO düzeyinde önemli artış olduğu gözlendi (P?0.001). Propolis grubu CAT aktivitesi ve MDA seviyesinde kontrol grubuna göre anlamlı azalmalar saptanırken, NO düzeyinde önemli artış gözlendi (P?0.001).Sıçan kalp dokularında; L-NAME uygulanan grupta CAT aktivitesi ve MDA miktarında, kontrol grubuna göre anlamlı artışlar (P<0.01) gözlenirken, NO seviyesinde önemli azalma belirlendi (P=0.012). L-NAME + propolis grubunda ise L-NAME grubu ile karşılaştırıldığında CAT aktivitesi ve MDA değerinde önemli azalmalar (P<0.01) saptanırken, NO düzeyinde anlamlı artış (P=0.012) olduğu tespit edildi. Propolis grubu CAT ve MDA değerlerinde kontrol grubuna göre anlamlı azalmalar (P<0.01) elde edilirken, NO miktarında önemli artış gözlendi (P=0.012).Elde edilen bu veriler sonucunda, NO inhibitörü olan L-NAME uygulanmış sıçanlarda meydana gelen oksidatif stresin propolis tarafından giderilebileceği biyokimyasal analizler ile ortaya konulmuştur.Anahtar sözcükler: Böbrek, Kalp, Katalaz (CAT), L-NAME, Malondialdehit (MDA), Nitrik oksit (NO), Oksidatif stres, Propolis, Sıçan
In this study, some biochemical analyses have been conducted on kidney and hearth tissues to determine the protective role of propolis eliminating oxidative stress created by L-NAME (N-Nitro-L-arginine methyl estere) which inhibitor of nitric oxide (NO) to Wistar albino rats.In the study, the experiment animals divided into four groups; control, propolis, L-NAME, and L-NAME+propolis.In the rat kidney tissues; compared with the control group, significant increases were determined (P?0.001) on the activity of catalase (CAT) and malondialdehyde (MDA) level in L-NAME group aso significant decrease in the level of NO was observed. On the other hand, in L-NAME + propolis group, as well as significant decreases were determined on CAT activity and MDA level compared with L-NAME group also significant increase in the level of NO was observed (P?0.001). Compared with the control group, significant decreases were determinedon the CAT activity and MDA level in propolis group and also significant increase was determined in the level of NO (P?0.001).In the rat heart tissues; compared with the conrol group, significant increases (P<0.01) were determined on the activity of CAT and MDA level in L-NAME group and also significant decrease in the level of NO was determined (P=0.012). On the other hand, in L-NAME + propolis group, as well as significant decreases were determined on CAT activity and MDA level (P<0.01) compared with L-NAME group also significant increase in the level of NO was observed (P=0.012). Compared with the control group, significant decreases were determined on the CAT activity and MDA level in propolis group (P<0.01) and also significant increase was determined in the level of no (P=0.012).As a result of these data, it has been determined with the biochemical analyses that propolis eliminates the effects of oxidative stres caused by the L-NAME which the inhibitor of NO.Keywords: Kidney, Heart, Catalase (CAT), L-NAME, MDA (Malondialdehyde), Nitric Oxide (NO), Oxidative stress, Propolis, Rat
