    摘要: A method for rapid purification of a blood component from blood is described in which the blood plasma is first separated from the cellular blood elements by any conventional means, such as centrifugation. An affinity cartridge is then activated with a molecule, such as an amino acid, which binds with a blood component such as plasminogen. The separated blood plasma is then passed through the affinity cartridge such that the blood component is retained by the affinity cartridge. Thereafter, the blood component is eluted from the affinity cartridge by passing a buffer solution containing a releasing agent through the affinity cartridge. This releasing agent disengages the blood component from the affinity cartridge. The releasing agent is then separated from the eluted solution by passing the eluted solution through a device, such as an ion exchange, gel filter, or size exclusion device. The isolated plasminogen solution is then concentrated by a factor of from 2 to 10. The separated blood component, e.g. plasminogen, is then converted to plasmin by adding a known amount of an enzyme to the solution from which the releasing agent has been removed.

    摘要: A process is disclosed for liquefying the vitreous humor of an eye. The process includes the steps of delivering plasmin into the vitreous of the eye and incubating the vitreous and plasmin together for a period of time. Plasmin may be introduced through injection or a sustained release device. Plasmin may be used to treat a pathological condition of the eye such as diabetic retinopathy, macular hole, macular pucker, intraocular infection, foreign intraocular material and retinal detachment.

    摘要: Methods of modifying total MMP activity levels in the vitreous of an eye are provided. In a preferred embodiment, the method results in reduced MMP activity and comprises introducing plasmin into the vitreous of the eye. Enzyme assisted vitrectomy procedures are also provided, and comprise introducing plasmin into the vitreous in an amount sufficient to induce posterior detachment of the vitreous, mechanically detaching the vitreous from the eye, introducing a replacement fluid into the eye, and introducing plasmin into the eye in an amount sufficient to decrease the total MMP activity in vitreous. Considering the purported roles of MMPs in a variety of vitreal pathologies, the present invention provides methods of inhibiting the progression of various disease conditions, including prolifertaive diabetic retinopathy.
