20080312139	Use of Pharmaceutical Composition Containing Epidermal Growth Factor (EGF) for Diabetic foot Amputation Prevention - The invention relates to the use of Epidermal Growth Factor (EGF) in a preferably-Injectable pharmaceutical composition which is administered by means of infiltration into and around chronic cutaneous ischaemic lesions in order to prevent diabetic foot amputation. Said composition can be administered to recently-created surgical surfaces damaged by the effect of acute reperfusion with oxygenated blood following prolonged ischaemia, thereby preventing further surgical procedures and favouring the preservation of the extremity. The aforementioned composition can be used to improve (i) the cell microenvironment, thereby increasing the reparative and defensive capacity and viability of the is tissues and (ii) the cicatrisation of cutaneous ischaemic lesions, thereby stimulating cell proliferation. The invention is suitable for use in human, veterinary and experimental medicine, specifically in vascular angiology and surgery, dermatology, burn treatment and reconstructive surgery and geriatric medicine. Said composition can be used for recalcitrant ulcers which are associated with lesions in the macro and/or microvasculature, patients with inadequate lymphatic and/or venous return and ulcers or other lesions which are difficult to cicatrise and/or heal.	12-18-2008

20090104223	Method for Obtaining Antigenic Aggregates and the Use Thereof in Formulations - The invention relates to a method for obtaining aggregated antigenic structures that are capable of enhancing an immune response to aggregate antigens administered systemically and/or mucosally generating powerful immune response and to the chemical structures resulting from the application of said method, to the formulations obtained from such structures and their use. The method describes the obtention of novel aggregate antigenic structures by using aggregating, delipidating or oxidating agents or compounds enabling the release of lipids from the particles and their heterogeneous aggregation, wherein aggregates with particle sizes of between 30 and 500 nm are subsequently selected by means of a molecular exclusion process. The aggregation state can also be provoket inside the yeast by changing incubation conditions. The resulting structures can be used conveniently adjuvated or in a formulation in which several antigens can be introduced, wherein synergism between said components is found with respect to the immunogenicity of the response obtained. The preparation may also contain stabilizers and preservatives. The resulting antigenic structures can be used in the pharmaceutical industry as preventive or therapeutic vaccine formulation both for human and veterinary use and as part of diagnostic system.	04-23-2009

20110250196	PHARMACEUTICAL COMPOSITION USING GONADOTROPIN - RELEASING HORMONE (GNRH) COMBINED VARIANTS AS IMMUNOGEN - A pharmaceutical composition using natural gonadotropin-releasing hormone (GnRH), and/or some of its mimetic peptides, indistinctly bound by its amino or carboxyl extremes to a carrier molecule; in one case by its carboxyl extreme and in the other case by the amino terminal extreme, thus eliciting a faster and more potent immunological response against the endogenous GnRH hormone. This finally leads to the ablation of the GnRH and consequently of the rest of the involved hormones in the stream GnRH/LH-FSH/Testosterone-(estrogens). An advantage of this formulation consists on facilitating the exposition to the immune system of a greater number of epitopes of the GnRH or its mimetics, minimizing thus the steric hindrance produced by the carriers. This invention has a direct application in the castration of pets and animals of economic interest, in the control of human fertility as well as in the treatment of hormone-sensitive tumors, such as that of the prostate, the breast, ovary, the endometry, testicles, hypophysis, salivary glands and other kinds of human tumors.	10-13-2011
