Novel materials to enhance corneal epithelial cell migration on keratoprosthesis.
PURPOSE To introduce a new modification for silicone optical core Keratoprosthesis. METHODS Using mixtures of 2-hydroxyethyl methacrylate and acrylic acid polydimethylsiloxane (PDMS) films were modified with two-step oxygen plasma treatment, and then type I collagen was immobilised onto this modified surfaces. Both the biocompatibility of the modified films and cell behaviour on the surface o...
متن کاملImmune response to biologic scaffold materials.
Biologic scaffold materials composed of mammalian extracellular matrix are commonly used in regenerative medicine and in surgical procedures for the reconstruction of numerous tissue and organs. These biologic materials are typically allogeneic or xenogeneic in origin and are derived from tissues such as small intestine, urinary bladder, dermis, and pericardium. The innate and acquired host imm...

متن کاملSpecific biologic effects of intestinal glucagon-like materials.
It has been demonstrated that gastrointestinal extracts contain substances which react immunologically with antibodies prepared to pancreatic glucagon. These extracts have been termed intestinal GLI for glucagon-like immunoreactivity, or enteroglucagon. To determine whether GLI has specific biological effects, studies were designed using the criterion of effect with antiglucagon antibodies. The...
متن کاملSpectrophotometric Determination of Microgram Quantities of Copper in Biologic Materials.
A procedurefor the determination of microgramquantities of copper in biologicmaterial is described. The sample is wet-ashed with a nitric acid-perchloric acid mixture. The copper is extracted from an alkaline solutionof the ash with a solutionof diphenylcarbazide in benzene. Absorbanceof the red complex is read at 540 m1&. The copperin as little as0.5 ml. of serum can be determined and the meth...
