Dietary supplements contain not only macro- and microelements, but also elements which affect human metabolism. Many products available on the market contain chromium compounds together with chitosan used as a dietary supplement enhancing the digestion of lipids. The studies involved natural chitosan from krill available on the market, with the deacetylation degree of 85 to 95%, and dietary supplements...
Bile salts play an important pathogenic role in the development of Barrett adenocarcinoma (BA). However, the precise role of different bile salts in this process is still unknown. The aim of the present study was to compare the effects of two different bile salts, deoxycholic acid (DCA) and ursodeoxycholic acid (UDCA) on the expression of COX-2, CDX-2 and DNA repair enzymes (MUTYH, OGG-1) in the Barrett...
The aim of the study was to estimate sorption degree of selected bile acids (lithocholic acid - LCA and cholic acid - CA) with 1 mmol/L and 6 mmol/L concentration as well as that of cholesterol by legumes. It was shown that bile acids sorption degree depended on the variety of seeds (the highest sorption ability had pea, while lentil showed the lowest one), grinding degree (bile acids were bound better...
Adsorption of common bile acids namely lithocholic (LCA), dexycholic (DCA) and cholic (CA) acids and cholesterol by fiber of carrots, cabbage and apples raw and after heat treatment, respectively, was estimated. It was shown that degree of bile acids adsorption depends on kind of the raw material, type of heat treatment and type of bile acids. Fiber carrots had higher sorption than cabbage and apples...
Rats, after cannulation of the common bile duct, duodenum and vena cava posterior were infused i.d. with sodium taurocholate to partially maintain the enterohepatic circulation of bile acids. Four-h i.V. infusions of glucagon, Boots secretin, Boots CCK and OP-CCK were continued together with bile acid administration. The bile was collected throughout the experiment and the bile volume, bile acid,...
