Protein malnutition‐induced exocrine pancreas dysfunction

The exocrine pancreas

This seminar text reviews various forms of enzyme supplementation used clinically in digestive and absorption disorders. Enzyme supplementation plays an integral role in the management of various digestive disorders, particularly with regard to exocrine pancreatic insufficiency. However, application of enzymes may also be beneficial for other conditions associated with poor digestion including ...

Exocrine pancreas cancer

Characterization of Ca2+-activated protein phosphatase activity in exocrine pancreas.

Ca2+-activated protein phosphatase activity was demonstrated in mouse pancreatic acinar cytosol with alpha-casein and skeletal-muscle phosphorylase kinase as substrates. This phosphatase activity preferentially dephosphorylated the alpha subunit of phosphorylase kinase. After DEAE-cellulose chromatography, the Ca2+-activated phosphatase activity became dependent on exogenous calmodulin for maxi...

Unstimulated Secretion of Protein from Rat Exocrine Pancreas Cells

Our earlier work demonstrated that the rate of protein synthesis in the exocrine cells of the rat pancreas is constant in different physiological states, including prolonged fasting. In this study we have followed the fate of the protein in the pancreatic cells of the fasting animal in vivo as well as in vitro. The data were obtained by quantitative radioautography and by biochemical determinat...

The Exocrine Pancreas: Normal and Abnormal Functions

The selection of topics, caliber of participants and content of the proceedings of this symposium reflect the high standards of the Ciba Foundation for scientific excellence. The broad range of topics covered by international authorities, together with the discussion, has been extremely well edited and the material is compiled in a logical sequence. The section on ultrastructure and histochemis...
