Description
MEANS AND METHOD FOR INCREASING SKIN RESPIRATION
TECHNOLOGY REVIEW
It is known that human skin respires, obtaini oxygen form the bloodstream, as a function of the cell li in the skin tissue. Furthermore, the rate of respiratio declines with age. Young skin respires more rapidly an absorbs greater quantities of oxygen. U.S. Patent No 2,320,478 to Sperti discloses the application of an extrac from bakers' yeast to human skin, in order to increas respiration of skin cells, and apparently improve th cosmetic appearance of skin. The extract also produce increased respiration of rat skin. Both bakers' yeast an brewers' yeast are technically classified as Saccharomyce cerevisiae. The Sperti patent, and all other reference cited herein, are incorporated by reference.
Methods have also been previously disclosed fo accelerating wound healing. In particular, Goodson et al. Journal of Surgical Research. Vol. 21, p. 125-129 (1976*) discloses a material described as "Skin Respiratory Factor" sometimes referred to as "SRF", which is a water solubl extract of brewer's yeast. As described in Goodson et al. SRF is an ingredient in a proprietary hemorrhoidal product sold under the trademark PREPARATION H. Goodson et a evaluated the effect of SRF on wound healing since it ha been shown to influence oxygen consumption by fibroblasts and since it was known that some aspects of wound healin could be influenced by an agent altering oxygen consumption The material studied by Goodson et al. contained 8100 Unit of SRF per gram ("Units of SRF/g"), wherein 1 Unit of SR increases the uptake of oxygen by minced rat abdominal ski (1 milligram dry weight) by 1% in a one hour measurement b Warburg manometry. In view of their in vitro and in viv experiments, Goodson et al. concluded that the yeast extrac tested was capable of stimulating wound oxygen consumption epithelization, and collagen synthesis. Goodson et al als
noted that the yeast extract produced early hair growth wound sites treated with the extract.
Kaplan, Arch. Surg.. Vol. 119, p. 1005 (Septemb 1984) investigated the extract used by Goodson et a supra. Kaplan refers to the extract as live yeast ce derivative or LYCD, and examined its effect on the rate burn wound healing in humans. Kaplan concluded that of LY was able to accelerate wound healing beyond its normal ra Kaplan stated that the resulting stimulated angiogenesis, well a the increase in oxygen consumption and colla synthesis noted by Goodson et al., supra. may provide explanation for the enhanced wound healing. This effect also discussed in Federal Register. Vol. 43, No. 151 (Aug 4, 1978). Other techniques for healing burned skin incl that disclosed in U.S. Patent 4,438,099 to Azzariti, wh requires the application of a spray of Candida kruseii burned skin, forming a crust over the wound. This is s to allow for a more rapid healing and skin regeneration the affected area. The patent states that the treatment also effective with open sores, such as varicose ulcers decubitus ulcers.
It would be desirable then to have a means wh enhances respiration of mammalian skin, since would heal can be influenced by such a means. Further, a means wh promotes healing of the skin would be useful in treatment of skin injuries, such as burns and incisions.
SUMMARY OF THE INVENTION The present invention provides a method and me for enhancing respiration of mammalian skin (which will referred to simply as skin) and, in particular in promot healing of injured skin. The invention is based on discovery that picolinic acid (pyridine-2-carboxylic ac enhances cell respiration which, as described above, associated with promoting healing of a skin injury promoting hair growth.
In the method of the present invention, composition consisting essentially of picolinic acid or alternatively, which comprises picolinic acid substantiall free of impurities from yeast, is applied to skin. Th compositions preferably exhibit at least 50,000 Units of SR activity per gram, as defined above, and further preferabl at least 500,000 Units of SRF activity, per gram of th composition.
Skin injuries which may be treated by the metho include, but are not limited to, burns. In the performanc of the present method, picolinic acid is typically provide in a carrier which is suitable for cutaneous application
For example, picolinic acid may be provided in an ointment cream, lotion or spray. Also contemplated is a dressing which can b applied to a skin injury, which dressing comprises a bandag and one of the picolinic acid compositions described
Further contemplated are compositions for topica application to the skin, comprising a suitable excipient fo skin application and sufficient picolinic acid to provid the composition with at least about 25,000 Units of SR activity per gram, preferably at least about 50,000 Unit per gram and more preferably at least about 500,000 Units.
In treating skin, it is anticipated tha compositions as described above will be applied to the woun for at least about ten days and then, depending upon th seriousness of the wound, up to 30 days or possibly more. Of course, in practice one would typically simply appl compositions of the present invention until the wound wa completely, or near completely, healed.
When weights of picolinic are referred to, thi includes both the anion or the corresponding portion of a compound such as picolinic acid, whether or not dissociated. Further, the total amount of picolinic acid in solution includes both dissociated and undissociated forms so that "picolinic acid" allows for adding to a solution, a
picolinate compound which would produce free picolinate io in water.
DRAWINGS Embodiments of the invention will now described, with reference to the drawings which general show the effect of picolinic acid in increasing cell growt and more particularly, in which:
Figure 1 illustrates the effect of growing yea cells in deficient media cultures, either in a control, with added picolinic acid, or a zinc salt (as zinc sulfa or zinc dipicolinate) ;
Figure 1A illustrates the growth of a yea culture in a complete medium, either in a control, or wi added picolinic acid or chromium salt (as chromic chlori or chromic tripicolinate) ; and
Figure 2B illustrates the increase in growth fou in each of the cultures identified in Figure 2A, followi the incubation period.
DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION The present inventors have now quantitat picolinic acid in yeast and have identified the enz picolinic carboxylase in yeast (which is involved in production of picolinic acid from tryptophan) , and desig experiments to compare chromic tripicolinate, zi dipicolinate, and picolinic acid on their ability to eff oxygen uptake by mouse skin or mouse liver cells. 1. Oxygen Uptake By Skin Cells
In a first series of experiments 0.1 millili ("ml") of aqueous solutions of (1) picolinic acid at concentration of 5 milligrams per milliliter ("mg/ml") , ( chromic tripicolinate (approximately 1 mg/ml concentratio and (3) zinc dipicolinate (approximately 1 mg/ concentration) , were added to 3,0 ml of a phosphate-gluc buffer media (pH approximately 7.4) that contained 100 mouse skin. The rate of oxygen uptake was measured with oxygen electrode over a period of approximately 1.0 min until the basal (i.e.. control) rate was established,
then the rate with the additive was measured ove approximately 10 minutes. It was found that in thos samples containing the added picolinic acid,- the rate o oxygen uptake increased by 20% over the basal rate, wherea the chromic tripicolinate and zinc dipicolinate did no produce any detectable increase in oxygen uptake. It shoul be noted that a 20% increase in oxygen uptake with 100 mg o rat skin, would correspond to 2,000 Units of SRF per 0.5 n of picolinic acid. Thus picolinic acid contains 4,000,00 Units of SRF/g.
2. Oxygen Uptake By Liver Cells
Another series of experiments was performed usin the same parameters as described in the precedin experiment, except that 20 mg of mouse liver cells per 3 m of media were used rather than the 100 mg of mouse ski cells per 3 ml of media. In this series of experiments, th uptake of oxygen by the cell suspension was increased b 340% in the presence of the picolinic acid (in comparison t the control) , whereas the chromic tripicolinate and zin dipicolinate did not produce any detectable increase i oxygen uptake. In an additional experiment under these sam conditions, 15 mg of impure SRF from yeast was added to th same cell suspension, and oxygen uptake increased by 180 over the basal rate. Thus, the 5 mg/ml solution o picolinic acid used in this set of experiments, was 48 time more active than the preparation of crude SRF tested.
The foregoing experiments show then, tha picolinic acid (which has now been discovered to be presen in yeast) , considerably increases oxygen uptake by cells, both in comparison to a control and also in comparison to preparation of crude SRF extract from yeast. THese result indicate that picolinic acid is the SRF factor in previousl disclosed yeast extracts. However, to confirm the efficac of picolinic acid as a factor which may enhance ski healing, a further series of experiments were performed t ascertain the effect of picolinic acid on cell growth. These experiments are detailed below.
3. Growth In De icient Liquid Media
In a first series of experiments, an isolated pu culture of commercial bakers yeast (sold under t trademark "RED STAR BRAND", available from Universal Foo Corp., Milwaukee, Wisconsin, U.S.A.) was grown in a comple agar medium sold under the trademark "DIFCO YM" (availab from Difco, Inc., Detroit, Michigan, U.S.A.), a transferred to a deficient liquid growth medium which described by Mirsky, et al., J. Inorg. Biochem.. Vol. 1 p. 11, (1980) . The foregoing deficient medium is free amino acids and trace metals and contains 2% glucos vitamins, and minerals needed for cell growth. Vario 'DIFCO' media are described in detail in "Difco Manua Culture Media and REagents for Microbiology: , 10th editio published by Difco Laboratories, Detroit, Michigan, U.S. (1984) . The yeast culture was grown in the deficient medi and then harvested. The resulting cells were th resuspended in a number of aliquots of 25 ml of deficie media to produce in each culture a starting yea concentration of about 5.5 to 6.0 X 107 cells/ml. A contr culture received no added zinc salt or picolinic acid, whi other cultures received sufficient zinc sulfate, picolin acid, or zinc dipicolinate to produce a resulti concentration of 50 ng of zinc per ml (in the case of zi sulfate) , or 250 ng/ l (in the case of picolinic acid) 240 ng/ml (in the case of zinc dipicolinate) . The cultur were then grown at 30°C with continuous shaking for fi hours. The cell concentration in the cultures was count again, and the growth increase calculated according to t formula;
Growth Increase = (final cell concentrati minus initial concentration) divided initial cell concentration. "Growth Increase" is sometimes referred to herein as increase in cell number or count, and may be expressed simply a number or as a percent. The increase in ce number (as defined above) was calculated for the sample
and the results (mean, from several experiments) plotted Figure 1. As can be seen from Figure 1, the addition of t picolinic acid produced a 12% greater increase in ce growth under the conditions of the experiments. 4. Growth In Complete Liquid Media
A third series of experiments were performed usi the complete medium, "DIFCO YM". The foregoing yeast medi contains a yeast extract, a malt extract, peptone, dextros and agar. Sufficient chromic chloride (CrCl3) and chrom tripicolinate were added to respective 100 ml aliquots the "DIFCO YM" medium to result in a chromium concentrati of 0.1 ng/ml in each, while sufficient picolinic acid w added to another aliquot to provide a picolinic aci concentration of 0.8 ng/ml. A 100 ml control aliquot "DIFCO YM" medium did not receive any chromium or othe added growth promoter. Baker's yeast was suspended in eac of the 100 ml aliquots to provide an initial cell count a follows:
Initial cell count of control = 3 X 105 cells/ml initial cell count in culture to which picolinic aci added = 2.1 X 105 cells/ml; initial count in culture t which chromic chloride added = 3 X " 105 cells/ml initial cell count in culture to which chromi tripicolinate was added = 2.5 X 105 cells/ml. The samples were grown at 30βC for 36 hours. The final cel count of each culture (mean from a number of experiments) i illustrated in Figure 2A. Figure 2B illustrates th increase in cell number (mean) , as previously defined.
As can be seen from Figure 2A, the addition of th picolinic acid resulted in an increase of cel concentration which was approximately 56% greater than tha of the control or the culture which received added chromi chloride.
5. Growth In Complete Solid Media In a further series of experiments, supplement were added to potato dextrose agar ("PDA"; in particular PDA sold under the trademark "BACTO-POTATO DEXTROSE AGAR"
available from Difco, Inc., Detroit, Michigan, U.S.A.), medium approved by a number of organizations for t detection and enumeration of yeasts. Cultures were prepar using a strain of baker's yeast different from the used the preceding set of experiments. The supplements we added to PDA at the following concentrations (per ml PDA) 400 ng picolinic acid, 40 ng tryptophan. the average yea colony count was 11% to 18% greater than the count obtain with unsupplemented control cultures as shown in the resul below:
ADDITIONS TO CULTURES Picolinic acid
The above results then, illustrate that picoli acid, now known to be present in yeast (which has been sho to increase the rate of healing of a skin injury) , b increases oxygen utilization of cells and additional increases cell growth. These factors indicate t picolinic acid is also the skin respiratory factor in ye extracts. Various modifications and alterations to embodiments of the invention described above, can of cou be conceived by those familiar with the art. According the present invention is not limited to those embodime described in detail, but includes all such modifications alterations.
