Claims
- 1. A pharmaceutical composition for treating tumors selected from the group of bovine squamous cell carcinoma, bovine fibrosarcoma, equine sarcoid, equine melanoma, equine squamous cell carcinoma, canine mammary tumors, canine adenoma and canine melanoma, comprising an anti-tumor effective amount of a combination of an effective amount of a purified pyridine-soluble extract obtained from a microorganism selected from the group consisting of M. bovis BCG, M. phlei, M. smegmatis, M. kansasii, Nocardia rubra, Corynebacterium diphtheriae and Corynebacterium parvum, said extract obtained by:
- (a) preparing a whole cell paste of said microorganism;
- (b) washing said paste;
- (c) treating said paste with pyridine to produce an extract and a residue;
- (d) removing said pyridine from said extract; and
- (e) dialyzing said dried extract to obtain said purified pyridine-soluble extract, an effective amount of trehalose dimycolate; and an effective amount of an acetone precipitated by-product of endotoxic glycolipids extracted with chloroform methanol; and a pharmaceutically acceptable carrier.
- 2. The composition of claim 1 wherein the amount of said extract is up to about 40 milligrams, the amount of trehalose dimycolate is up to about 6 milligrams, and the amount of said acetone precipitated by-product is up to about 20 milligrams.
- 3. The composition of claim 1 wherein said composition is in
- 4. The composition of claim 1 wherein said composition is in the form of an oil droplet emulsion.
- 5. The composition of claim 2 wherein the amount of said extract is between about 200 and 5000 micrograms, the amount of trehalose dimycolate is between about 50 and 1000 micrograms and the amount of said acetone precipitated by-product is between about 150 and 1000 micrograms.
- 6. A method of treating tumors selected from the group consisting of bovine squamous cell carcinoma, bovine fibrosarcoma, equine sarcoid, equine melanoma, equine squamous cell carcinoma, canine mammary tumors, canine adenoma and canine melamoma in warm blooded animals comprising administering an effective amount of the composition of claim 1 to said warm blooded animals by injection directly into the tumor.
- 7. The method of claim 6 further comprising injecting into said tumor said composition containing between about 375 and 2500 micrograms/milliliter of said pyridine-soluble extract product and between about 375 and 1250 micrograms/milliliter of each of trehalose dimycolate and said acetone precipitated by-product.
