Abstract
Abstract The invention provides proteolytic enzyme-containing compositions which, on administration, optimize the in vivo viscosity of the mucuses and which are characterized by bringing the magnitude of the in vitro viscosity to a value generally between those values obtained when mucus is subjected to identical treatments with trypsin and chymotrypsin; they are also characterized by being insensitive to trypsin inhibitors.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
106 words
A method for increasing the speed of absorption of digested foodstuffs and medicines which comprises orally administering to an animal an amount sufficient to increase the speed of absorption of digested foodstuffs of a product consisting essentially of a proteolytic enzyme produced by culturing Streptomyces fradiae in a fermentation medium until said proteolytic enzyme has the following characteristics: a. an aqueous solution containing 250 A.U. of a said enzyme and having a pH of 7.5 reduces the viscosity of 1 gram of intestinal mucus from 65 to 35 percent in 30 minutes; and b. the enzyme is insensitive to trypsin inhibitors, and a physiological acceptable carrier.
Claim 2
Dependent Claim
32 words
A method according to claim 2, in which the quantity of proteolytic enzyme product orally administered to an animal is from 500 to 200,000 A.U. per kilogram of body weight per day.
