Abstract
Abstract Medical protein hydrolysate is produced from the feet of young freshly killed poultry. The protein, thus produced, is an extract of polypeptides and amino acids. It is in the form of a powder or a gel, each of which is suitable for topical application to living cells of animals and humans for aiding in healing. The process of production of the protein hydrolysate includes treating the washed and comminuted poultry feet or other source of protein with a dilute acid, preferably acetic acid, and drying under low heat conditions the resulting solution to a powder or to a gel. The process of using the protein hydrolysate including periodic topical application to a traumatized (wound) area. In the event that treatment is to be below the surface, an aqueous solution of the protein can be injected into the area to be treated.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
66 words
A therapeutic agent comprising a non-antigenic, protein hydrolysate having polypeptides and amino acids derived by: comminuting the immature poultry feet and washing them; commingling said comminuted immature poultry feet with a dilute, mild organic acid at a pH between 6.5 and 3.6 at an elevated temperature up to 155° F; removing the fat constituent; and removing the solubilized protein and dissolved minerals at the elevated temperature.
Claim 2
Dependent Claim
66 words
A therapeutic agent comprising a non-antigenic, protein hydrolysate having polypeptides and amino acids derived by: comminuting the immature poultry feet and washing them; commingling said comminuted immature poultry feet with a dilute, mild organic acid at a pH between 6.5 and 3.6 at an elevated temperature up to 155° F; removing the fat constituent; and removing the solubilized protein and dissolved minerals at the elevated temperature.
Claim 3
Dependent Claim
19 words
The therapeutic agent as claimed in claim 1 wherein said elevated temperature is between 130° F and 140° F.
Claim 4
Dependent Claim
22 words
The therapeutic agent as claimed in claim 1 wherein said poultry feet are derived from chickens; not more than 9 weeks old.
Claim 5
Dependent Claim
16 words
The therapeutic agent as claimed in claim 1 wherein said mild organic acid is acetic acid.
Claim 6
Dependent Claim
64 words
The therapeutic agent as claimed in claim 1 wherein in the step of comminuting the immature poultry feet and washing them, said poultry feet are ground and pretreated with a mild organic acid solution from 1 to 11/2 % by weight acid at from 70° to 90° F for from 8 to 12 hours, after which pretreatment the poultry feet are washed with water.
Claim 7
Dependent Claim
25 words
The therapeutic agent as claimed in claim 1 wherein said removing the fat constituent step includes cooling the solution and separating out the fat layer.
Claim 8
Dependent Claim
35 words
The therapeutic agent as claimed in claim 6 wherein said agent is a dehydrated gel and is derived by reheating the cooled solution and air drying of the reheated solution to form this dehydrated gel.
Claim 9
Dependent Claim
31 words
The therapeutic agent as claimed in claim 1 wherein said agent is a powder and is derived by spray drying the resultant solution from which the fat material has been removed.
Claim 10
Dependent Claim
16 words
The therapeutic agent as claimed in claim 1 wherein said removing the precipitate step includes decanting.
Claim 11
Dependent Claim
19 words
The therapeutic agent as claimed in claim 1 wherein said removing the precipitate step includes filtering through diatomaceous earth.
Claim 12
Dependent Claim
30 words
The process of treating damaged higher animal tissue for therapeutic purposes comprising the applying to said tissue an effective amount of a non-antigenic protein hydrolysate as claimed in claim 1.
Claim 13
Dependent Claim
13 words
The process of claim 11 wherein said protein hydrolysate is an aqueous gel.
Claim 14
Dependent Claim
23 words
The process of claim 12 wherein said tissue includes an open wound and said protein hydrolysate is a dry powder covering said wound.
Claim 15
Dependent Claim
14 words
The process of claim 11 wherein said protein hydrolysate is injected into a tissue.
Claim 16
Dependent Claim
37 words
A therapeutic agent comprising, a non-antigenic, protein hydrolysate having a mixture of polypeptides and amino acids therein, said protein hydrolysate being the soluble constituent derived from immature poultry feet which have been hydrolized by mild acid hydrolysis.
Claim 17
Dependent Claim
37 words
A therapeutic agent comprising, a non-antigenic, protein hydrolysate having a mixture of polypeptides and amino acids therein, said protein hydrolysate being the soluble constituent derived from immature poultry feet which have been hydrolized by mild acid hydrolysis.
Claim 18
Dependent Claim
25 words
A therapeutic agent comprising, a non-antigenic, protein hydrolysate derived by mild acid hydrolysis from immature poultry feet in which the anti-bodies are not fully developed.
Claim 19
Dependent Claim
25 words
A therapeutic agent comprising, a non-antigenic, protein hydrolysate derived by mild acid hydrolysis from immature poultry feet in which the anti-bodies are not fully developed.
