The formation of zymogen granules in the pancreas
Electron-dense, granular (rarely vesicular) bodies, some 30 m/x or more in diameter, are seen lying in the ground cytoplasm in the vicinity of the smooth-surfaced membranous complex. They often appear to be embedded in amass of amorphous material, which is of about the same electron-density as the granules themselves. Granules and vesicles, similar in appearance to those mentioned above, have a...
متن کاملEnzyme secretion in the absense of zymogen granules.
Pure pancreatic juice was collected from the cannulated common bile duct of anesthetized rats after an overnight fast. Digestive enzyme secretion was followed in these animals during and after the progressive degranulation of acinar cells produced by sequentially applied cholinergic stimuli. The kinetics of degranulation, a progressive decrease in the number of zymogen granules in acinar cell...
متن کاملHypersecretion of zymogen granules in the pathogenesis of cystic fibrosis.
In the submandibular saliva of 10 cystic fibrosis subjects and 10 controls the turbidity and elevated calcium, protein, and amylase concentrations of the cystic fibrosis secretions, and precipitation of calcium and phosphate in a ratio consistent with hydroxyapatite have been confirmed. By electron microscopy the centrifuged deposits of the cystic fibrosis saliva were seen to be composed predom...
متن کاملSpectrophotometric Determination of Hydralazine Using p-Dimethylaminobenzaldehyde
A new spectrophotometric method for the assay of hydralazine hydrochloride in bulk and dosage forms has been developed. The procedure is based on a condensation reaction between alcoholic solution of hydralazine and acidic solution of pdimethylaminobenzaldehyde to generate an instant greenish-yellow coloured product. The hydrazone formed absorbed visible light strongly and optimal detector resp...
متن کاملSpectrophotometric determination of Cilastazol using p-dimethylaminobenzaldehyde
A simple accurate and reproducible spectrophotometric method was established for the estimation of Cilastazol based on the formation of condensation product. The method is based on the formation of yellow colored chromogen, when the drug reacts with p-Dimethylaminobenzaldehyde (PDAB). The colored species has an absorption maximum at 425 nm and obeys Beer's law in the concentration range of 6-10...
