Abstract: Type 1 Diabetes and other virus-induced or autoimmunological diseases are treated with Human Immune Factors. These Human Immune Factors are extracted from blood cells by activating said blood cells with human lymphoblastoid interferon-alpha or staphage lysate or other activator or combination of activators. Human Immune Factors are purified and made suitable for pharmaceutical use by isolating compounds with molecular weights between about 1,000 and about 25,000 daltons.

Abstract: New and improved methodology for the diagnosis of a disease from blood sample analysis is disclosed and comprises: the preparation of a putative antigenic body substance extract, which is specific to disease-sensitized blood leukocytes, from the pooled, like body substances of a plurality of donors known to have the disease of interest; the mixture of said extract with the blood sample leukocytes; the promotion of the reaction therebetween to modify a characteristic of the disease-sensitized leukocytes, if any, of the blood sample; and the determination of the extent, if any, to which said characteristic has been modified. In multiple sclerosis diagnosis, said body substance may be blood or urine; while for malignant disease (for example breast cancer, or cancer of the head and neck) said body substance may be blood, urine, pleural fluid, ascites fluid, supernates of tumor cells or tumor cells grown in culture media.
