Abstract: Short bowel syndrome may result from extensive resection of the small bowel. Because the transport of bile salts, cobalamin (vitamin B12), and cholesterol is localized to the ileum, resection of this region is poorly tolerated. Patients who have had their ileum resected cannot absorb cholesterol, long chain fatty acids, fat soluble vitamins (A, D, E, and K), cobalamin (vitamin B12), and the metal ions (Ca2+, Mg2+, and Zn2+). Liposomes are suitable biological vehicles for the non-parenteral delivery of these fat and water soluble nutrients directly into the blood of patients with the small bowel syndrome. Liposomes are compartmentalized vesicles consisting of bilayer lipids enclosing aqueous chambers. The lipid and water soluble nutrients can be commercially packaged in their respective compartments and delivered directly into the blood stream of these patients, thereby bypassing the intestines. The liposomes can pass through water barriers.

Abstract: The invention is a method of treating aging skin and wrinkles by using a combination of commercially prepared growth factors, platelet derived growth factor (PDGF), epidermal growth factor (EGF), and insulin-like growth factors (IGF-I and IGF-II) incorporated into a cosmetic and/or a pharmaceutical preparation and applied to the face to stimulate skin cell renewal and fibroblasts to divide and synthesize elastin, collagen, proteoglycans, and new connective tissue, thereby reducing wrinkles, restoring elasticity, resiliency, and suppleness to the skin. The invention is also a method of treating aging skin and wrinkles using an individual's own blood to obtain the serum and plasma fractions which are rich in platelet derived growth factor (PDGF), and insulin-like growth factors, (IGF-I and IGF-II.
