... suspected above all. A biological approach to vagal tone was attempted by assaying intragastric pepsin and serum pepsinogen and calculating the ratio of pepsin to acid in control infants, and by assaying serum pepsinogen levels in infants having suffered an apparently life-threatening event (ALTE) or who...

...Per T. Sangild; Marian Silver; Abigail L. Fowden; Alan Turvey; Bent Foltmann Development of the porcine gastric proteases (chymosin, pepsin A, B and C) has been studied in the fetal pig in the last third of gestation (term 115 days). The possibility that the prepartum rise in circulating cortisol...

... only (0.77–2.3 mU/mg tissue). The localization of lipase activity in the stomach was mapped and compared to that of pepsin. The data show that the highest lipase activity was found in biopsy specimens of gastric mucosa from the cardia area (5.32 ± 1.29–8.32 ± 0.93 U/mg protein), and the lowest...

...Michael J. Henschel; Michael J. Newport; Veena Parmar The electrophoretic mobilities of proteases present in gastric juice taken within 10 h of birth from 5 healthy, premature infants were compared with calf chymosin, pig pepsin A and human adult gastric juice. The juice from 2 infants contained...
