Mucoprotein secretion in calculous gallbladder

: Secretion of mucoproteins or mucine (MP) have been studied as possible markers in several pathological conditions of the digestive tract, such us colonic polyposis or gastric dysplasia. In the gallbladder (VB) it has been established that form the core of crystalization for the calculi. A study in 100 gallbladders have been made based on the utility of the analysis of the qualitative and quantitative modifications of MP in lithogenesis. It was been determined by histochemical techniques the three main types of MP (neutral, low and high sulphated acid) to evaluate the alterations in the process of lithiasis. Results show a high production of the MP in VB with lithiasis, presenting in 97% a mixed composition of MP (48.9% of 2 types, and 3 types in 46%), without a predominating type in this pathology.
