The change of Ig-forming cells in the gallbladder mucoderm were studied in the rabbit models.One hundred rabbits were randomly divided into the control group(Con,n=10),simple biliary obstruction group(BO,n=45)and biliary obstruction and infection group(BOI,n=45).The results showed that only a few Ig-forming cells presented in the gallbladder mucoderm of normal rabbit.At the 3rd,7th and 14th day,the quantities of IgG and IgA-forming cells in the mucoderm in BO group remained unchange,but increased much higher in BOI group(Plt;0.001),especially in IgG formation.This study suggests that the gallbladder of rabbit may be the important place of Ig-formation.The quantities of Ig-forming cells in bilitary tract may have a close relationship with the gallstone formation.
