Abstract: The invention pertains to eutrophic drug composition containing transferrins, particularly human transferrins. This composition allows the toxic effects of cytotoxic drugs such as cyclosporin when used at high dosages or over a prolonged period of time to be alleviated or suppressed.

Abstract: The invention pertains to a process for the production of a pharmaceutical composition effective for controlling in a recipient mammalian host, particularly man, immune reactions of the type that are involved in graft of foreign tissue or cells, particularly transplantation of foreign tissues, organs or cells, particularly of allogeneic or even xenogeneic origin, or in immunodeficiency-linked diseases, which pharmaceutical composition is characterized by an active principle consisting of pooled transferrin-derived glycans obtained from a number of donors sufficient to allow the pool to contain sufficient phenotypic information required to ensure an induction of tolerance against antigens in an immuno-depressed host grafted with said antigens, after that host had been administered an amount of such pooled transferrin glycans effective to induce said tolerance.

Abstract: A method for controlling immune reactions to a foreign tissue or a foreign cell in a recipient host mammal to enhance tolerance of the recipient host mammal towards a grafted foreign tissue or a grafted foreign cell. This method involves administering a transferrin and a foreign tissue or a foreign cell antigen from the same genetic donor to a previously immunosuppressed recipient host mammal.

Abstract: The use of transferrin glycans, particularly human transferrin glycans for the production of eutrophic drug compositions is disclosed. These transferrin glycans allow the toxic effects of cytotoxic drugs, e.g., cyclosporin, when used at high dosages or over prolonged times to be alleviated or even suppressed.

Abstract: A method for treating the skin and/or scalp of a human host by the administration of a melatonin composition in order to improve the cosmetic or physical appearance of the skin and/or scalp, and the compositions therefore.

Abstract: Water soluble biologically active fraction obtainable from the physiologically inter-cellular medium bone-marrow and process for preparing said fraction and the pharmaceutical compositions containing said fraction. The characteristics are notably the following: it is substantially free of the inhibitors having molecular weights lower than 30,000; it is lyophilizable without loss of biological properties; it exhibits the biological activities in the form of a solution having a pH of at least 7; it stimulates H-thymidin incorporation by bone-marrow cells in vitro and in vivo; the water soluble fraction is capable of controlling the immune reactions of a host against allogenic cells or tissue.

Abstract: The invention concerns a new composition or combination of drugs effective to selectively control the immune reactions which are evoked in a host by the administration of antigens.It comprises active components capable of simultaneously blocking the .alpha.-adrenergic receptors of the cells for catecholamine, blocking the dopaminergic receptors of the cells and increasing the synthesis of serotonin. Preferred drug combinations according to the invention contain in association phentolamine, haloperidol, L-5-hydroxy-tryptophane and possibly dopamine.
