Abstract: Preparations of drugs in admixture with certain ligands are described which, when administered to animals or humans, are less toxic than conventional drug preparations. Although the toxicity of the drug-ligand preparations described is greatly reduced, the drug retains pharmacological activity.

Abstract: Diacyl phosphatides having a polyunsaturated carboxylic acid at the 2 position are found to have cytotoxic effect against tumor cells. Subject compositions may be employed in vivo or in vitro for inhibiting tumor cell growth, either by themselves or in combination with other cytotoxic drugs. The compositions may be administered as liposomes.

Abstract: Monoclonal antibodies which demonstrate specific reactivity to cholesterol and methods for the detection of high levels of cholesterol by contacting biological specimens containing cholesterol with the monoclonal antibodies and measuring the formation of antigen-antibody complexes by immunosorbent assay.

Abstract: A method for the specific detection of inositol and phosphatidylinositol within a model membrane such as liposomes or within a cellular system such as T lymphocytes.

Abstract: A novel treatment has been discovered for interrupting the life cycle of malaria parasite during its development in the liver of the vertebrate host. The subject invention involves a method of chemotherapy against sporozoite-induced malaria by administering an 8-aminoquinoline drug, such as primaquine, encapsulated within liposomes containing glycoconjugates, to a vertebrate host which has been infected with sporozoites of the parasites. Preferred species of glycoconjugates have a terminal glucose or galactose moiety, such as present in glycosyl ceramide, galactosyl ceramide, lactosyl ceramide, or in glycoproteins.

Abstract: An improved method is provided for the chemotherapy of leishmanial infects. An 8-aminoquinoline anti-leishmanial agent is encapsulated within liposomes and the liposome-encapsulated drug is injected into the body. Subject use of a liposome carrier has produced marked enhancement of the effectiveness of the drug against leishmanial parasites in the liver (such as characteristic of infections which are difficult to treat).

Abstract: An improved method is provided for the chemotherapy of leishmanial infections. The anti-leishmanial agent is encapsulated within liposomes and the liposome-encapsulated drug is injected into the body. Subject use of a liposome carrier has produced marked enhancement of the effectiveness and duration of anti-leishmanial action of meglumine antimoniate, and of sodium stibogluconate, drugs which are recommended widely for therapy of leishmaniasis.
