Abstract

Prolonged exposure to amniotic fluid causes the intestinal changes such as serosal edema, thickening,fibrous coating,and adhesions in gastroschisis. The effect of continuous delivery of methylene blue (CDMB) from a drug delivery system and daily injection of methylen blue (DIMB) on the intestines was evaluated using a chick embryo gastroschisis model.Fifty fertile eggs were divided into5 groups: preliminary study (PSn=10), amnio-allontoic fluid (AAF) control (AAC, n=10), just gastroschisis (JG, n=10), gastroschisis pretreated with daily injection of methylene blue (GP-DIMB, n=10) and gastroschisis pretreated with continuous delivery of methylene blue (GP-CDMB, n=10). The PS group was also divided into 2 subgroups to determine the biochemical differences between the amniotic and allontoic fluid. Gastroschisis was created surgically at the 14th day of incubation. İn GPMB group daily methylene blue injection (5 mg/g) was administered into AAF for 5 days. In GP-CDMB, 25 µg/g methylene blue loaded polymer (Hydroxy-Propyl Methyl Cellulosa- Ethyl Cellulosa "HPMC-EC") was placed into AAF. A significant decrease in mortality and intestinal damage and higher ganglion number were observed both macroscopically and microscopically in the group GPCDMB compared to JG (p

Özet

Gastroşizis'de, uzun süreli amniyotik sıvıyla temas, barsaklarda serozal ödem, kalınlaşma, fibröz doku ve yapışıklık gibi değişikliklere sebep olur. İlaç taşıyıcı sistemlerden devamlı salınan metilen mavisi ve günlük uygulanan Metilen Mavisi (MM)'nin etkileri, civciv embryosu gastroşizis modelinde değerlendirildi. Elli adet döllenmiş yumurta 5 gruba ayrıldı: Ön çalışma (PS, n=10), Amniyo-allantoik sıvı kontrol (AAC, n=10), yalın gastroşizis (JG, n=10), günlük metilen mavisi injekte edilerek tedavi edilmiş gastroşizis,(GP-DIMB, n=10) ve ilaç taşıyıcı sistemlerden devamlı salınan metilen mavisiyle tedavi edilen gastroşizis (GPCDMB). Ön çalışma grubunda amniyotik ve allantoik sıvı biyoşimik farklılıkları iki alt grupta araştırıldı. İnkübasyonun 14. gününde cerrahi gastroşizis yapıldı. GP-DIMB grubunda, AAF içine günlük MM enjeksiyonu (5 µg/g) 5 gün boyunca uygulandı. GP-CDMB grubunda, 25mg/g MM yüklenmiş polimer (Hydroxy-propyl methyl cellulose-Ethyl cellulose) AAF içine yerleştirildi.Mortalite ve barsak hasarlanmasının, polimer ile tedavi edilen GPCDMB grubunda yalın gastroşizis grubuna kıyasla önemli derecede azaldığı (p
