Description

United States Patent Oflice Re. 28,011 Reissued May 14, 1974 ABSTRACT OF THE DISCLOSURE [This application is a continuation of copending application Ser. No. 864,526, which was filed Oct. 7, 1969, in the name of Matthew C. Urbin, now abandoned] This is a Reissue of Pat. No. 3,639,579, issued Feb. I 1972, which is a continuation of copending application Ser. No. 864,526, now abandoned.
BACKGROUND OF THE INVENTION The enzyme names used in the following specification are drived from Recommendations 1964 of the International Union of Biochemistry published in Comprehensive Biochemistry, Marcel Florkin, Elsevier, Amsterdam, NY. (1965).
In the practice of the present invention, these amines are destroyed by the application of suitable oxidase enzymes and by the presence of a catalase enzyme which will provide the necessary oxygen. The catalase enzyme may in some instances be present in the tissue, or it may be supplied as an ingredient of the preparation.
The action when, for example, a monoamine oxidase is used, may be represented as follows:
Monoamine RCH: NH: or H20 ---0 (Amine) Oxldase 115:0 mo. NH.
The following references are give for the isolation of monoamine oxidase and diamine oxidase. They are typical of the prior art isolation procedures for these enzymes.

The prior art pharmaceutical preparations for the treatment of hemorrhoids are generally not completely satisfactory due primarily to the lack of complete understanding in the prior art as to the cause and cure of hemorrhoids. It has been determined that the cause of itching and swelling in the region of the colon which produces 70 hemorrhoids is due primarily to the formation of amines by bacteria in the colon.
DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION The following formulations have been made and have proven to be completely satisfactory in immediately terminating itching caused by hemorrhoids, and in reducing the swelling within one or two days.
3 FORMULATION A (a) An ointment base and an enzyme stabilizing agent was compounded by melting 50 grams polyethylene glycol 6000 with 30 grams of polyethylene glycol 1540, and by then cooling the mixture to 50 C.
(b) Five milligrams of monoamine oxidase (Sigma Type 1: crude beef plasma) was then dissolved in 20 cc. of 0.1 molar phosphate buffer (pH 7.2), the phosphate buffer serving to hold the pH of the preparation in a predetermined range and to prevent the preparation from assuming the pH of the area being treated. The tentative activity is as follows:
1 mg. will produce an initial change in the optical density (OD) of about 0.1/minute at 25 C. in a threemilliliter reaction mixture containing benzylamine. Reference-Taber et al. Journal of Biological Chemists, 208 645 (1964).
(c) The formulation was prepared by mixing (a) and (b) and by allowing the mixture to solidify.
On the basis of the monoamine oxidase in the Formulation A, it was speculated that the addition of catalase may well have a synergistic effect on the reaction by removing the most noxious of the end products, and it would also serve as an agent for supplying one of the necessities for the reaction, namely oxygen. Accordingly, the following Formulation B was compounded, and found to be completely effective.
FORMULATION B (a) An ointment base and enzyme stabilizing action was compounded by melting 50 grams of polyethylene glycol (Carbowax) 6000 with 30 grams of polyethylene glycol (Carbowax) 1540, and by then cooling the mixture to 50 C.
(b) Five milligrams of catalase (Sigma stock #C-lO purified from beef plasma) (activity 2000-5000 sigma units/ gram) was then dissolved in 20 cc. of 0.1 M phosphate buffer (pH 7.2) (one Sigma unit will decompose one micromole of hydrogen peroxide per minute at pH 7.0 at 25 C. while the hydrogen peroxide concentration falls from 10.3 to 9.2 micromoles per milliliter of reaction mixture). The rate of disappearance of the hydrogen peroxide is followed by observing the rate of decrease in optical density at 240 micromoles).
(c) Mix (a) and (b) and allow the mixture to solidify.
The rationale of Formulation B may be represented by the following:
Monoarnlne o H R511 NH Oxldase 2 2 Catalese It has also been found that histamine, cadaverins and putrescine are formed in the colon, and these elements also are effective in the formation and stimulation of hemorrhoids. For that reason, in the following preparation, Formulation C, diamine oxidase is added to oxidize the aforesaid elements. For example, one milligram of diamine oxidase will oxidize approximately 0.7 micromole of putrescine per hour at a pH of 7.2 and at 37 C.
FORMULATION C Formulation C was found to be very effective in the treatment of hemorrhoids. Moreover, tests were made on all the preceding formulations, and they were found to maintain their activity indefinitely. For example, Formulation B was tested at two month intervals for almost a year and was found to lose none of its activity.
FORMULATION D (a) An ointment and enzyme stabilizing agent was compounded by melting 25 grams of polyethylene glycol (Carbowax) 6000 with 15 grams of polyethylene glycol (Carbowax) 1540, and by then cooling the mixture to 50 C.
(b) 2.5 milligrams of monoamine oxidase (Sigma Type 1: crude beef plasma); 2.5 milligrams diamine oxidase (Sigma Grade 11 from hog kidney); and 2.5 milligrams catalase (Sigma stock #Cl0purified powder from beef plasma) were then dissolved in 10 cc. of 0.1 M. phosphate buffer (pH 7.2).
(c) The formulation was prepared by mixing (a) and (b) and allowing the mixture to solidify.
FORMULATION E (a) An ointment and enzyme stabilizing agent was compounded by melting 25 grams of polyethylene glycol (Carbowax) 6000 with 15 grams of polyethylene glycol (Carbowax) 1540, and by then cooling the mixture to 50 C.
(b) As a second step, 2.5 milligrams diamine oxidase (Sigma Grade 11 from hog kidney), and 2.5 milligrams catalase (Sigma stock #C-10-purified powder from beef plasma) were then dissolved in 10 cc. of 0.1 molar phosphate buffer (pH 7.2).
(c) The formulation was prepared by mixing (a) and (b) allowing the mixture to solidify.
FORMULATION F (a) An ointment and enzyme stabilizing agent was compounded by melting 25 grams of polyethylene glycol (Carbowax) 6000 with 15 grams of polyethylene glycol (Carbowax) 1540, and by then cooling the mixture to 50 C.
(h) Then, 2.5 milligrams of monoamine oxidase (Sigma Type 1: crude beef plasma); and 2.5 milligrams catalase (Sigma stock #C-l 0-purified powder from beef plasma) were dissolved in 10 cc. of 0.1 M phosphate buffer (pH 7.2).
(c) The formulation was prepared by mixing (a) and (b) allowing the mixture to solidify.
FORMULATION G (a) An ointment and enzyme stabilizing agent was compound by melting 25 grams polyethylene glycol (Carbowax) 4000 with 20 grams polyethylene glycol (Carbowax) 400 and by cooling the mixture to 50 C.
(b) 0.1 milligram of monoamine oxidase (Sigma Type 1: crude beef plasma); 0.1 milligram diamine oxidase (Signma Grade 11 from hog kidney); and 0.1 milligram catalase (Sigma stock #Cl0-purified powder from beef plasma) were then dissolved in 10 cc. of 0.1 M phosphate buffer (pH 7.2).
(c) The formulation was prepared by mixing (a) and (b) allowing the mixture to solidify.
FORMULATION H (a) An ointment and enzyme stabilizing agent was compounded by melting 25 grams polyethylene glycol (Carbowax) 4000 with 20 grams polyethylene glycol (Carbowax) 400 and by cooling the mixture to 50 C.
(b) 2.5 milligrams of monoamine oxidase (Sigma Type 1: crude beef plasma); 2.5 milligrams diamine oxidase (Sigma Grade 11 from hog kidney); and 2.5 milligrams catalase (Sigma stock #C-lO-purified powder from beef plasma) were then dissolved in 10 cc. of 0.1 M phosphate buffer (pH 7.2).
(c) The formulation was prepared by mixing (a) and (b) allowing the mixture to solidify.
FORMULATION I (a) An ointment and enzyme stabilizing agent was compounded by melting 25 grams polyethylene glycol (Carbowax) 4000 with 20 grams polyethylene glycol (Carbowax) 400 and by cooling the mixture to 50 C.
(b) 50.0 milligrams of monoamine oxidase (Sigma Type 1: crude beef plasma); 50.0 milligrams of diamine oxidase (Sigma Grade 11 from hog kidney); and 50.0 milligrams catalase (Sigma stock #C-l0purified powder from beef plasma) were then dissolved in cc. of 0.1 M phosphate buffer (pH 7.2).
(c) The formulation was prepared by mixing (a) and (b) and allowing the mixture to solidify.
The latter formulations were also found to be effective in the treatment of hemorrhoids. However, for universal application, and for most effective use, the Formulations C or D are considered to be the preferred formulations at present.
The invention provides, therefore, a formulation which is relatively simple and inexpensive to prepare, and which uses readily available and relatively inexpensive ingredients. The formulation is also easy to apply, and it has been found most effective in accomplishing its desired purpose.
It will be appreciated that although particular formulations have been shown and described, modifications may be made, and it is intended in the claims to cover all modifications which come within the spirit and scope of the invention.
