Abstract

Background/aims: The present investigation was carried out to evaluate the protective effect of the hydroalcoholic extract of Urtica dioica leaves on the quantitative morphometric changes in the liver of streptozotocin-induced diabetic rats. Methods: Thirty male Wistar rats were divided into control (G1), diabetic (G2), diabetic + Urtica dioica (G3) groups. The control group received only sham injections of intraperitoneal saline; the diabetic group received intraperitoneal saline for 5 days followed by streptozotocin (80 mg/kg) on the 6th day; and the diabetic + Urtica dioica group received 100 mg/kg Urtica dioica intraperitoneal (7) injections for 5 days and streptozotocin injection on the 6th day. After five weeks, the animals were sacrificed and whole livers removed. Liver specimens were used for quantitative morphometric analysis after hematoxylin and eosin staining. All data were statistically analyzed by one-way ANOVA and expressed as the mean with standard error of means. Results: In the G3 (diabetic + Urtica diocia) group, the mean surface area of hepatocytes in the periportal zone (Z1) was greater than in G2 (diabetic) and G1 (control) groups, but this difference was not significant. No alteration was observed in the surface area of hepatocytes in the perivenous zone (Z3) in the diabetic+Urtica dioica (G3) group compared to the diabetic (G2) group. The mean nuclear area of hepatocytes of the rats in the diabetic+Urtica dioica (G3) group was higher in Z1 and lower in Z3 than that of rats in the diabetic (G2) group. The mean diameter of hepatocyte nuclei in the diabetic + Urtica dioica (G3) group was lower than that of diabetic (G2) and control (G1) groups in both Z1 and Z3. Conclusions: This study revealed that the administration of extract of Urtica dioica leaves before induction of diabetic with streptozotocin has a protective effect on the morphometric alterations of hepatocytes in the periportal and perivenous zones of the liver lobule in rats.

Özet

Amaç: Bu çalışmada, streptozin ile diyabet geliştirilen sıçanlarda, Urtica dioica yapraklarının hidroalkol ekstraktının, karaciğerde gözlenen kantitatif morfometrik değişiklikler üzerine olan koruyucu etkisinin araştırılması amaçlanmıştır. Yöntem: Otuz adet erkek Wistar cinsi sıçan kontrol (G1), diyabetik (G2) ve diyabetik+Urtica dioica (G3) olmak üzere 3 gruba ayrıldılar. Kontrol grubuna sadece intraperitoneal salin enjeksiyonu yapılırken, diyabetik gruptaki sıçanlara 5 gün salin enjeksiyonun ertesinde 6. gün intraperitoneal olarak 80 mg/kg streptozosin uygulandı. diyabetik+Urtica dioica grubunda ise 5 gün boyunca 100 mg/kg Urtica dioica enjeksiyonunu takiben 6. günde 80 mg/kg streptozosin uygulandı. Beş hafta takibin ertesinde tüm sıçanlar sakrifiye edilerek karaciğerleri bütün olarak çıkartıldı. Karaciğer örnekleri hematoksilen ve eosin ile boyandıktan sonar kantitatif morfometrik analizler için kullanıldılar. Tüm veriler ortalama ± standard sapma kullanılarak tanımlandı ve tek yönlü ANOVA ve değerlendirildi. Sonuç: G3'de (Diyabetik+Urtica dioica) periportal bölgedeki (Z1) hepatositlerin ortalama yüzey alanlar G2 (Diyabetik) ve G1'dekilerden daha büyüktü ancak fark istatistiksel olarak anlamlı bulunmadı. Ayrıca, perivenöz (Z3) bölgedeki hepatositlerin yüzey alanları karşılaştırıldığında G3 (Diyabetik+Urtica dioica) ile G2 (Diyabetik) arasında anlamlı farklılık tespit edilmedi. Ortalama çekirdek yüzey alanları G3 (Diyabetik+Urtica dioica) grubunda G2 (Diyabetik) ile karşılaştırıldığında, Z1'de daha yüksek ve Z3'de daha düşük bulundu. Ortalama hepatosit çekirdek çapı Z1 ve Z3 bölgelerinde, G3'de (Diyabetik+Urtica dioica), G2 (Diyabetik) ve G1 (Kontrol) gruplarına göre daha düşük bulundu. Yorum: Bu çalışmanın sonuçarına göre; sıçanlarda, Urtica dioica yapraklarının ekstraktının uygulanmasının, streptozosin ile diyabetik geliştirilen sıçanlarda karaciğer lobulündeki periportal ve perivenöz bölgelerdeki hepatositlerde gözlenen morfometrik değişiklikler üzerinde koruyucu etkisi mevcuttur.
