Description
USE OF SHARK LIVER OIL FOR LOCAL TREATMENT OF SKIN DISEASES OF DOMESΗC ANIMALS
The present invention relates to the use of shark liver oil comprising alkyl glycerols for the preparation of a drug for the local treatment of skin diseases of domestic ammals e.g. horses, cattle, sheep, dogs and cats as well as a method of treatment of skin diseases of domestic animals. Such diseases are for example summer sore, sarcoids, such as Equine sarcoids, favus and scurf of different origin, greasy heels, mud fever, rain scalds, saddle sore, girth galls, and ringworm.
BACKGROUND OF THE INVENTION
In ancient times shark liver oil, extracted e.g. from Greenland shark and from the so called Seamouse, Chimera monstr osa, was used within the traditional medicine for a variety of therapeutic purposes, such as combating weakness and irritation of the respiratory and digestive organs, gland diseases, bee stings and wound healing, etc.
Crude shark liver oil contains squalene, etherlipids (alkyl glycerols) and triglycerides. The composition of the oil varies widely from one shark species to another. In some species the oil contains as much as 90% squalene, while the ether lipids or the triglycerides dominate in other.
Due to their varying properties, compounds derivable from the shark liver oil have found applications within the various fields of use.
US 5079003 A to Scaffidi A. discloses creams or lotions incorporating emulsions offish oils, such as shark liver oil, squalane, and squalene that are used as moisturisers, as hand and body lotions and as sunburn preventives. Cosmetic and moisturising compositions are described also comprising numerous other ingredients.
In US 3 294639 to Chalmers et al, the oral or parenteral use of alkylglycerols, more specifically batyl alcohol, chimyl alcohol and selachyl alcohol, in the treatment of inflammatory diseases in warm-blooded ammals is disclosed.
2
However, there is nothing disclosed or suggested in prior art about the unexpected advantages obtained by the local application of shark liver oil on the skin of domestic ariimals such as horses suffering from skin diseases. Diseases which successfully are treated with the drug according to the invention are e.g. summer sore; sarcoids, such as Equine sarcoids; favus and scurf of different origin such as those emerging by infection with Dermatophilus, e.g. dermatophilosis; greasy heels, mud fever, rain scalds, saddle sore, girth galls; and ringworm.
Summer sore is a skin disease affecting domestic animals, mainly horses, associated with itching and involving loss of hair with πinning, ulcerous skin. The background to summer sore is not entirely clear but it is believed to be associated with sun shine and heat, but may also depend on allergic reactions to insect bites. It is usually treated in that the horse is covered with a horse-cloth and stabled, the latter especially by night. Treatment with cortisone preparation which alleviates the pain has also been suggested. Other alternatives are treatment with some homeopathic preparations e.g. one named Okozon added to the fodder of the animal or an oil called "PROB oil" comprising root extracts, herbs, oils and char coal. However, there remains a need for a preparation that gives a quick healing, is cheap and effective.
Equine sarcoids are fibroblastic skin tumours and papillomas, attributed to viruses such as retro- and papillom viruses. There are several types of sarcoids with different appearance, some flat and fleshy, other forming wart-like bumps. The tumours do not spread in the body but might spread locally in the skin and cause considerable inconveniences. The lesions are notoriously difficult to treat due to infiltrative growth, with multiple lesions resulting in high rates of recurrence. One way of treatment has been by surgery or laser surgery, other freezing, immunotherapy, radiation treatment, hyperthermia, bri^hing with etching substances or injection with cytotoxic drugs directly into the tumour.
Dermatophilus congolensis causing dermatophilosis, penetrates into the skin when it is softened due to wet surroundings or cracked under dusty and dry conditions and makes the skin scurfy. The treatment available hitherto has been to remove the scurf, cut the hair, shampoo the affected
3
area with anti-septic shampoo and to apply antibiotic ointment. Sometimes also injections of antibiotics have been necessary.
Ringworm is the name of a group of fungal diseases of the skin of man and domestic animal marked by the formation of ring-shaped pigmented patches covered with vesicles and scales and caused by dermatophytes. In order to get ride of ringworm not only the animal but the whole stable as well as the equipment must be disinfected. However, eventually, the animal becomes immune to the disease but the inconveniences during the primary stage are considerable.
The problem to be solved by the present invention, thus, is to provide a preparation which in a simple and effective way by local application cure the diseases mentioned above.
DEFINITION OF THE INVENTION
The above presented problem is solved by the present invention which relates to the use of shark liver oil for the preparation of a drug for the local treatment of skin diseases of domestic animals such as e.g. horses, cattle, sheep, dogs and cats etc. The shark liver oil used for the preparation of the drug is crude or refined shark liver oil comprising alkyl glycerols in an amount of up to 100 % and used in a concentration of from 1 to 100 %. Other ingredients that may be added to the shark liver oil to enhance the penetration of the active compound into the skin, to preserve it and to make it convenient to handle, are selected from acidifying agents, emollients, emulsifying agents, surfactants, preservatives, viscosity controlling agents, anti-oxidants, solvents, etc.
The skin diseases which may be treated with the drug according to the invention are e.g. summer sore, sarcoids such as Equine sarcoids, favus and scurf of different origin such as those emerging with infections by Dermatophilus, e.g. dermatophilosis, greasy heels, mud fever, rain scalds, saddle sores, girth galls, and ringworm.
The preparation according to the invention alleviates the itch of summer sore and gives a clear improvement after a treatment period of 2 to 5 days and eventually, completely healed after continuous treatment during at least one week.
A suitable treatment frequency of summer sore is by local application of the preparation to the affected area 2 to 3 times per week during at least one week.
Sarcoids were treated by the local application of the preparation according to the invention on the skin of the animal once daily and when a clear improvement was noticed the preparation was applied twice a week.
Substances included in the preparation are e.g., acidifying agents, emollients, emulsifying agents, surfactants, preservatives, viscosity controlling agents, anti-oxidants, solvents, etc.
An agent suitable as emulsifier, emollient and surfactant is e.g. Tefose 2561 comprising PEG-6 stearate (50-72%), Ceteth-20 (10-24.9%), Glyceryl stearate (5-9.9%), and Steareth-20 (5-9.9%), included in amounts of up to 30 %
Useful as preservatives and acidifiers are all substances accepted of the man skilled in the art for veterinary medicine treatment. Suitable examples are sorbic acid, lactic acid, salicylic acid, or other α-hydroxy acids, each in amounts of up to 10 %.
Among suitable anti-oxidants, e. g. ascorbyl palmitate can be mentioned, however all anti- oxidants acceptable within the art of veterinary medicine and known to the man skilled may be used. The amounts included are decided according to stability test results in line with established practise.
The preparation can be in any form suitable for topical application such as an ointment, a cream, a milk, a lotion, a liquid emulsion, a spray, an aerosol or a powder.
The preparation may be applied to the skin in any suitable way such as by rubbing, spraying, the application of liquid impregnated patches, drenched plasters, etc.
