Abstract

There are growing numbers of studies evaluating the pathogenic mechanisms which underlie in gallstone formation. Gallbladder motility and factors that influence gallbladder motility are particularly gaining much interest in recent years. Our objective for this study was to compare the effects of cholecystokinin (CCK) and erythro-mycin treatments on bile chemistry and gallstone formation in the aged guinea pigs. Study was held in Gulhane Research Laboratories. Two guinea pig groups (40, 1-mo old and 40, 3-yr old) were studied. Each group was subdivided into four subgroups of each including 10 animals. While one subgroup of each age group was placed on lithogenic diet only, one subgroup was treated with CCK, the other with erythromycin in addition to lithogenic diet for 4 weeks. 10 guinea pigs from each group remained on normal diet as control group. After 4 weeks, the presence of gallstone and bile chemistry including bile acid, cholesterol, lecithin and protein concentrations were evaluated. We observed no gallstones in 1-mo old group, while in 3-yr old group, 9 of 10 guinea pigs on lithogenic diet and 4 of 10 guinea pigs of each treatment subgroups and control group developed gallstones. Treatments with CCK and erythromycin showed similar effects on bile chemistry and stone formation. In conclusion, aging increases the formation of gallstones in the guinea pigs. Erythromycin seems as effective as CCK in reducing the gallstone formation by improving gallbladder motility. These results suggest that the use of erythromycin could be an alternative in prevention of gallstones for long-term treatment of patients.with biliary sludge.

Özet

Safra taşı oluşumunun altında yatan patojenik mekanizmaları incelemeye yönelik giderek artan sayıda çalışma vardır. Özellikle safra kesesi motilitesi ve motiliteyi etkileyen faktörler, son yıllarda çok fazla ilgi görmektedir. Biz de çalışmamızda, yaşlı guinea pig'lerde, safra taşı oluşumu ve safra kimyası üzerine kolesistokinin (CCK) ve eritromisinin etkilerini karşılaştırmayı amaçladık. Çalışma, GATA Araştırma Laboratuarlarında yapıldı. 40 adet bir aylık ve 40 adet üç yaşında olmak üzere, iki guinea pig grubu ile çalışıldı. Her bir grup kendi içinde 10'arlı olmak üzere dört alt gruba ayrıldı. Dört hafta süre ile her yaş grubundan birer alt grup sadece litojenik diyetle beslenirken, birer alt gruba, litojenik diyetle beraber CCK, diğer bir alt gruba ise diyetle beraber eritromisin tedavisi uygulandı. Her iki gruptan 10'ar guinea pig, kontrol grubu olarak normal diyetle beslendi. Dört hafta sonra, safra taşının varlığı ve safra asidi, kolesterol, lesitin ve protein konsantrasyonlarını içeren safra kimyaları değerlendirildi. Çalışma sonunda bir aylık grupta hiç safra taşı gözlenmezken, üç yaş grubunda sadece litojenik diyetle beslenen 10 guinea pig'in 9'unda ve her bir tedavi grubunun ve kontrollerin 4'er tanesinde safra taşı gelişti. CCK ve eritromisin tedavileri safra kimyası ve taş oluşumu üzerine benzer etki gösterdiler. Sonuç olarak, yaşla beraber, guinea pig'lerde safra taşı oluşum insidansı artmaktadır. Eritromisin tedavisi, yaşlı guinea pig'lerde, kese motilitesini düzelterek safra taşı insidansını, CCK tedavisi kadar azaltmıştır. Bu sonuçlar özelikle safra çamuru tespit edilen yaşlı hastaların uzun vadeli tedavilerinde, eritromisin kullanımının da bir alternatif olabileceğini göstermektedir.
