[Enzymatic activity and therapeutic action of pepsin K in chronic gastritis with secretory failure].

Pepsin K (chicken pepsin) in the test for hemoglobin proteolysis is 1.7 times superior to abomin (porcine pepsin) in the medium pH 2 and 44 times more potent in the medium pH 3. Even in pH 4 chicken pepsin retains its enzymatic activity while porcine pepsin in pH 4 looses its activity.

[Comparative experimental enzymatic activity and clinical efficacy of pepsin K and abomin].

Hen pepsin (pepsin K) in the experiment on proteolytic activity of hemoglobin surpasses porcine pepsin (abomin) with pH of medium 2 in 1.7 times, with pH of medium 3 in 44 times, that makes it more acceptable for treatment of enzymatic insufficiency of stomach. In the clinic reception of pepsin K in tablets for 4 weeks had a positive effect for all 10 patients after the surgical intervention on the stomach.
