Abstract

Purpose: To investigate the possible effect of intestinal obstruction on the offspring of lactating mothers. Materials and Methods: Pregnant Sprague-Dawley rats were used. Partial intestinal obstruction was induced on days 7 and 14 days of lactation. Surgery was performed on control animals without causing any obstruction. Then, 14 and 21 days after these applications, ileum tissue samples were taken from the animals and prepared for electron microscopic investigations. Thick sections were stained with toluidine blue and investigated under a light microscope; thin sections were stained with uranyl acetate-lead citrate and investigated under an electron microscope (Carl Zeiss EM900). Results: When compared with the control group, degeneration of the microvillus structure, mitochondrial swelling and appearance of giant vacuoles on the surface absorptive cells were detected in the offspring of rats with intestinal obstruction. These structural changes increased with the increasing duration of obstruction. Muscle structure seemed to be normal. Conclusion: The offspring of lactating rats may be affected by obstruction induced in the mothers, which could cause deterioration of the absorption mechanism.

Özet

Amaç: Bu çalışmada, bağırsak mukozasında epitel hücrelerde hipertrofi ve hiperplazi gibi değişikliklerin olaylandığı süt verme evresindeki sıçanların, ince bağırsaklarına uygulanan deneysel kısmi obstrüksiyonun, deneklerin yavrularına olası etkilerinin belirlenmesi amaçlanmıştır. Gereç ve Yöntem: Çalışmada Sprague – Dawley cinsi gebe sıçanlar kullanıldı. Laktasyonun 7 ve 14. günlerinde kısmi bağırsak obstrüksiyonu uygulandı. Kontrol grubu deneklerde de cerrahi girişim aynen uygulanmakla birlikte obstrüksiyon gerçekleştirilmedi. Uygulamayı izleyen 14 ve 21. günlerde her iki gruba ait yavrulardan alınan ileum doku örnekleri alışılmış elektron mikroskop izlem yöntemlerinden geçirildi. Kalın kesitler toluidin mavisi ile boyanarak fotoışık mikroskopta, ince kesitler ise uranil asetat – kurşun sitrat ile boyanarak Carl Zeiss EM900 elektron mikroskopta değerlendirildi. Bulgular: Kontrol grubu ile karşılaştırıldığında, obstrüksiyon uygulanan annelerin yavrularında, mikrovilluslarda bozulma, mitokondriyonlarda şişme ve emilim yapan hücrelerde iri vakuollerin şekillenmesi gibi çeşitli yapısal değişiklikler gözlendi. Bu değişikliklerin süre artımına koşut daha da belirginleştiği dikkati çekti. Kas yapısı normal olarak belirlendi. Sonuç: Sonuç olarak; süt verme evresinde anneye uygulanan ince bağırsak obstrüksiyonun, annenin emilim mekanizmasında olaylandırdığı aksaklıklar nedeniyle, uygulanan obstrüksiyondan yavruların da etkilendiği kanısına varılmıştır.
