Abstract

The important role of glucose in iron absorption is well known. This study was planned to examine the effects of insulin on iron absorption in diabetic rats. Material and Methods: For such a purpose four different groups of rats were selected and 59Fe radioiso-tope in dissolved in isotonic NaCI was orally infused into the duodenum through a catheter to a first group of animals (n=10). As second group diabetic rats received a duodenal infusion of radioactive 59Fe dissolved in isotonic glucose solution (n=7). A third group of diabetic rats received a duodenal infusion of radioactive 59Fe dissolved in hypertonic glucose solution (n=10). A fourth grouffof diabetic animals was given 59Fe orally after diabetes therapy with insulin (n=10) All diabetic groups rendered to diabetes by intraperitonal streptozotocin injection (60 mg/kg) The fourth group of di¬abetic animals were given 59Fe orally after diabetes therapy with intramuscular recombinant DNA originated human insulin (1U/kg/day). Blood samples were collected from the hearth by intracardiac puncture and absorbed 59Fe from duodenum concentrations, insulin levels and glucose concentrations were determined. Results and Conclusion: According to our results, the blood glucose levels of diabetic groups were found to be higher but the insulin levels lower than control group values (p

Özet

Amaç: Demir emiliminde glukozun önemi bilinmektedir. Çalışmamız diabetik hayvanlarda demir absorbsiyonu ve demir absorbsiyonunda insülinin etkisini incelemek amacıyla planlanmıştır. Materyal-Metod: Çalışmamızda dört farklı deney grubu oluşturuldu; Deney grupları; 1. Kontrol grubu (Gl): izotonik NaCI çözeltisi ile Fe59 uygulaması (n=10), 2. Diabetik grup (Gll): izotonik glukoz çözeltisi ile Fe59 uygulaması (n= 7), 3. Diabetik grup (Glll): hipertonik glukoz çözeltisi ile Fe59 uygulaması (n=10), 4. Insulin tedavili diabetik grup (GIV): hipertonik glukoz çözeltisi ile Fe59 uygulaması (n=10), olmak üzere ayrıldı. Diabet modeli deney grubundaki her bir hayvana intraperitonel olarak 60 mg/kg streptozotosin enjekte edilerek oluşturuldu. Dördüncü gruptaki diabetik sıçanlara, tedavi amacıyla kilogram başına 1 ünite /gün rekombinat DNA orjinii insan insülini enjekte edildi (int-ramüsküler). midenin pilor bölgesine kadar katater yerleştirildi. Tüm gruplarda sıçanlara oral yoldan duedonuma Fe59 verildi. Uygulamadan 1.5 sa. sonra intrakardiak ponksiyonla kan örnekleri alındı. Alınan kan örneklerinde % Fe59 düzeyi, glukoz konsantrasyonu ve insülin düzeyleri ölçüldü. Bulgular: Sonuçlarımıza göre diabetik grupların (Gll ve Glll) kan glukoz düzeyleri kontrol grubuna göre anlamlı olarak yüksek, insülin düzeyleri ise anlamlı olarak düşük bulunmuştur (p
