A method is provided for producing an effective adjuvant response or stimulating the immune response of a warm blooded animal which comprises administering to said warm blooded animal an effective amount of a composition comprising refined detoxified endotoxin in combination with a pharmaceutically acceptable carrier.

Refined detoxified endotoxin

The present invention is directed to a method of inhibiting to onset of septicemia and endotoxemia. The methods comprise administering to a warm-blooded animal an effective amount of a pharmaceutical composition comprising Monophosphoryl lipid A in combination with a pharmaceutically acceptable carrier.

Method of inhibiting the onset of septicemia and endotoxemia

The present invention is directed to a method of inhibiting the onset of acute radiation syndrome caused by the exposure of warm-blooded animals to a whole body dose of at least about 100 rads of x-radiation. The invention is also directed to a method of inhibiting the onset of septicemia. The methods comprise administering to a warm-blooded animal an effective amount of a pharmaceutical composition comprising refined detoxified endotoxin in combination with a pharmaceutically acceptable carrier.

Method of inhibiting the onset of acute radiation syndrome

A method of purifying crude trehalose dimycolates (TDM) is disclosed which comprises dissolving crude TDM in a solvent and then subjecting said solution to a low pressure silica gel column operating at a pressure between about 10 and 300 psi wherein the silica gel comprises particles in the range of between about 15 and 63 microns. The product of this process is also disclosed.

Purification of trehalose dimycolates

A stable composition containing cell wall skeleton (CWS) and trehalose dimycolates (TDM) which may be effectively reconstituted after lyophilization. The composition is useful in the treatment of various cancerous tumors in animals without side effects. Also disclosed is a method of producing the composition and a method of treating cancerous tumors in animals using said composition.

Stable composition and preparation thereof

A pharmaceutical composition comprising refined detoxified endotoxin, trehalose dimycolate, and an acetone precipitated by-product of endotoxic glycolipids extracted with chloroform-methanol (ACP) is disclosed which is useful for the treatment of cancerous tumors. Methods of using the composition for these purposes are also disclosed.

Refined detoxified endotoxin product

A pharmaceutical composition comprising refined detoxified endotoxin, cell wall skeleton and trehalose dimycolate is disclosed which is effective for the treatment of cancerous tumors. Methods of using the composition for these purposes are also disclosed.

A refined detoxified endotoxin (RDE) product is disclosed which, when combined with cell wall skeleton (CWS), results in a composition useful for the treatment of cancerous tumors. Methods of making RDE as well as methods of using the combination of RDE and CWS are also disclosed.
