of fat into the proximal small intestine consistently suppressed gastric motility. In rats with diversion of bile from the small intestine this inhibition failed to occur unless bile salts were added to the administered fat. When both bile and pancreatic juice were diverted from the small intestine...
These observed physiological changes are commonly associated with dietary intake, while the effects of digestive enzymes are specific to the nature of food components (e.g., pepsin for proteins, and lipase for lipids). Specifically, changes in the intestinal secretion of bile and pan...
Describe how bile and pancreatic juice secretion into the small intestine are regulated. Explain the pathway of bile to the duodenum. (a) What process occurs when bile is mixed with fats? (b) How does this process affect the rate of fat digestion?
In the duodenum, the two most important factors in the digestive process, are the intraluminal levels of pancreatic lipase (for fat hydrolysis) and of bile salts (for the solubilization of the lipids before and during lipolysis). FAT DIGESTION IN THE NEWBORN Whereas the absorption of dietary ...
Calcium-based kidney stone disease is a highly prevalent and morbid condition, with an often complicated and multifactorial aetiology. An abundance of research on the role of specific vitamins (B6, C and D) in stone formation exists, but no consensu
We initially developed an in vivo perfused rabbit oesophagus model that served to study the effects of various components of the gastroduodenal juice on several parameters of oesophageal injury. We have shown that pepsin causes severe morphological oesophagitis at an acidic pH but is ineffective at ...
Doses of ZNP were prepared in distilled water and were ultrasonicated for 15 min before its administration to the rats. For oral gavage, fruit juice was extracted simply by macerating the fruit with the help of mortar pestle and was later filtered with muslin cloth for further use and it ...
bile acids that are prone to enterohepatic circulation between the gallbladder and the liver. Cholesterol absorption in the intestine and cholesterol secretion into the bile both require bile salts, which are, together with enterohepatic circulation of BAs, crucial for balancing the plasma cholesterol ...
