Bu çalışmanın amacı Berberis crataegina DC. bitkisinin köklerinden elde edilen ekstraktın alloksan ile oluşturulan diyabetli ratlar üzerindeki etkilerini incelemektir. Materyal ve Metot: Çalışmamızda 36 Albino Wistar erkek rat kullanıldı. Ratlar her grupta 6 adet olmak üzere 6 gruba ayrıldı. Gruplar; 1. Sağlıklı kontrol grubu, 2. Diyabetli kontrol grubu, 3. Sağlıklı ve Berberis crataegina DC. su ekstresinin 600 mg/kg uygulanan grup, 4, 5 ve 6. gruplar diyabetli ve farklı dozlarda (dördüncü gruba 150 mg/kg, beşinci gruba 300 mg/kg, altıncı gruba 600 mg/kg) Berberis crataegina DC. su ekstresi uygulanan grup olarak belirlendi. 1. ve 2. grup hariç, diğer gruplara 19 gün intragastrik gavaj ile su ekstresi verildi. 5, 10 ve 19. günlerde ratların kuyruk veninden alınan kanlarda glukoz ölçümleri yapıldı. 19. günün sonunda ratlar sakrifiye edilerek alınan böbrek ve karaciğer doku örnekleri biyokimyasal ve histopatolojik olarak incelendi. Bulgular: Yapılan biyokimyasal analizler sonucunda diyabetli tedavi gruplarının ALP, AST, ALT, HbA1c, serum insülin, kan glukoz düzeylerinde istatistiksel olarak anlamlı (p&lt;0.005) azalma görüldü. Bitki ekstresinin artan dozuna bağlı olarak antihiperglisemik etkisinin olduğu tespit edilmiştir. Özelikle yüksek doz gruplarında böbrek ve karaciğer dokularında istatistiksel olarak (p&lt;0.05) iyileştirici etkilerin olduğu gözlemlenmiştir. Sonuç: Berberis crataegina DC. kökü su ekstresinin diyabetin meydana getirdiği komplikasyonlar üzerine olumlu etkisi olduğu tespit edildi. Yapılacak ileri düzey çalışmalarla desteklenmesi halinde bu bitkinin yeni sentezlenecek anti-diyabetikler için bir kaynak olabileceği kanaatindeyiz.

The aim of this study is Berberis crataegina DC. the aim of this study is to examine the effects of the extract obtained from the roots of the plant with alloxan on diabetic rats. Materials and Methods: 36 Albino Wistar male rats were used in our study. Rats were divided into 6 groups, 6 in each group. Groups; 1st healthy control group, 2nd the diabetes control group, 3th healthy and Berberis crataegina DC. 600 mg/kg of the water extract was applied to the group, 4th, 5th, and 6th groups with diabetes and at different doses (150 mg/kg to the 4th group, 300 mg/kg to the 5th group, 600 mg/kg to the 6th group) Berberis crataegina DC. water extract was determined as the applied group. Except for the 1st and 2nd groups, water extract was given to the other groups by intragastric gavage for 19 days. On the 5th, 10th and 19th days, blood glucose measurements were made from the tail vein of the rats. Finally, the rats have sacrificed, kidney and liver tissues were taken and examined biochemically and histopathologically. Results: As a result of the biochemical analyzes, a statistically significant (p&lt;0.005) decrease was observed in the ALP, AST, ALT, HbA1c, serum insulin, and blood glucose levels of the diabetic treatment groups. It has been determined that the plant extract has an antihyperglycemic effect depending on the increasing dose. It was observed that statistically (p&lt;0.05) curative effects were observed in kidney and liver tissues, especially in high-dose groups. Conclusion: Berberis crataegina DC. was determined that the root water extract had a positive effect on the complications caused by diabetes. We believe that this plant can be a source for newly synthesized anti-diabetics if supported by advanced studies.
