B3 strain was found to have a more depressing effect on IL-12 and TNF-α, than A13, in splenectomized groups.Conclusions:It has been determined that splenectomy leads to immunosuppression; that probiotics –especially the high EPS producing-have an indirect anti-inflammatory effect with cytokine regulation; and that with the cytokine profiles they exhibit, they sytematically support mucosal immunity.

Abstract

Objectives:Aim of this study was to determine the second phase changes that may occur after a splenectomy; when probiotics, with proven therapeutic effects of intestinal mucosal immunity and systemic immunity, are utilized.Materials and Methods:Total of 56 female Sprague-Dawley rats were used and divided into eight groups. Low exopolysaccharide (EPS) producing Lactobacillus delbrueckii subspecies bulgaricus A13 strain, or high EPS producing Lactobacillus delbrueckii subspecies bulgaricus B3 strain, was orally applied to the rats pre-operatively or post-operatively. Splenectomy was performed on the 8th day of the study and cardiac blood sampling and small bowel resection were performed on the 16th day.Results:In terms of systemic immunity assay whilst there was no significant difference found between IL-6 and IL-10, a significant difference was detected between the groups in TNF-α, TGF-β, IL-4, IL-12 and IL-12 / IL-4 statistical comparisons (p <0.05).A13 strain was observed to further increase TGF-β levels after a splenectomy, while further decreasing IL-4 levels. Also, A13 strain application in the splenectomized groups reduced TNF-α levels. TNF-α levels decreased in B3 strain treated groups; TGF-β elevation was found to be higher, and this strain reduced IL-12, IL-4 and IL-10. B3 strain was found to have a more depressing effect on IL-12 and TNF-α, than A13, in splenectomized groups.Conclusions:It has been determined that splenectomy leads to immunosuppression; that probiotics –especially the high EPS producing-have an indirect anti-inflammatory effect with cytokine regulation; and that with the cytokine profiles they exhibit, they sytematically support mucosal immunity.

Özet

Amaç: Bu çalışmamızda intestinal mukozal immünite ve sistemik immüniteyi iyileştirici etkileri kanıtlanmış olan probiyotiklerin kullanımı ile splenektomi sonrasında oluşabilecek ikinci faz değişiklikleri saptamayı amaçladık. Gereç ve Yöntem:Çalışmada toplam 56 adet Sprague-Dawleytipi dişi rat kullanılmıştır. Deney hayvanları toplam sekiz gruba ayrıldı. Ratlara gruplarına göre preoperatif veya postoperatif dönemde olmak üzere EPS‟si düşük Lactobacillus delbrueckii subspecies bulgaricus A13suşu veya EPS‟si yüksek Lactobacillus delbrueckii subspecies bulgaricus B3suşu probiyotik uygulandı. Çalışmanın 8. gününde splenektomi uygulandı ve 16. günde kardiyak kan alımı ve ince barsak rezeksiyonu uygulandı. Bulgular:Sistemik immünite açısından grupların istatistiksel karşılaştırmalarında, gruplar arasında TNF-α, TGF-β, IL-4, IL-12 ve IL-12/IL-4 arasında istatistiksel olarak anlamlı bir farklılık bulundu (p<0.05). Ancak IL-6 ve IL-10 açısından anlamlı bir farklılık saptanmadı.A13suşunun splenektomi sonrası gelişen TGF-yüksekliğini daha fazla artırdığı; IL-4‟ü ise daha da düşürdüğü saptanmıştır. Ayrıca, splenektomi uygulanan gruplarda A13suşu uygulamanın TNF-düzeylerini azalttığı tespit edilmiştir. B3suşu uygulanan gruplarda da TNF-düzeylerinin düştüğü; TGF-yüksekliğinin daha arttığı tespit edilmiş, IL-12, IL-4 ve IL-10‟u azalttığı saptanmıştır. B3suşunun splenektomi uygulanan gruplarda IL-12‟yi ve TNF-‟yı düşürücü etkisi A13‟e göre fazla bulunmuştur. Sonuç:Splenektomi ile immünosupressif bir tablo ortaya çıktığı; probiyotiklerin sitokin regülasyonu ile dolaylı olarak antiinflamatuvar bir etki oluşturdukları ve meydana getirdikleri sitokin profili ile sistemik olarak mukozal immüniteyi destekledikleri görülmüştür.
