Abstract: The invention relates to the inhibitory effects of dextrin sulphate on angiogenesis and in particular the treatment of diseases or disorders which would benefit from the administration of dextrin sulphate.

Abstract: A method of treating a patient having a highly vascular tumor includes administering a therapeutically effective amount of dextrin sulphate to the patient. The highly vascular tumor can be, for example, Kaposi's sarcoma. The treatment results in regression of the tumors and the improvement persists for a considerable time after completion of the treatment.

Abstract: The invention provides an agent against HIV and/or related viruses, comprising CD4 or a CD4-like substance and an H2 histone or an H2 histone-like protein. The content of the CD4 or CD4-like substance is preferably less than the antivirally effective dose of that substance alone. The invention also provides an H2 histone or an H2-like protein, for use in a method of medical treatment, in particular against HIV and/or related viruses, and also for use in the manufacture of a pharmaceutical composition against HIV and/or related viruses.
