66 results about "Lumbrokinase" patented technology

Lumbrokinase is a fibrinolytic enzyme present in the earthworm Lumbricus bimastus. It has been investigated as an experimental antithrombotic agent.

Lumbrukinase enteric-coated pellet capsule and preparation method thereof

The invention provides a lumbrukinase enteric-coated pellet capsule and a preparation method of the lumbrukinase enteric-coated pellet capsule. According to the preparation method, the centrifugal granulation technology is adopted, the lumbrukinase is prepared into pellet and is coated by low-temperature-filmed enteric coating and then is filled into a gastric soluble capsule; and a dried-powder wrapping method is adopted, which has the advantages of being short in preparation time, high in drug loading rate, high in yield of target pellet (20 to 30 meshes), and smooth and round in appearance of the target pellet. By adopting the lumbrukinase enteric-coated pellet capsule, the pellet can be dissolved and absorbed by the small intestine, so that the lumbrukinase can be effectively prevented from being damaged by gastric acid, and the treatment effect can be ensured; compared with common capsule, the capsule provided by the invention has the advantage that the pellet is filled in the gastric soluble capsule, so that the shortcomings that the powdered medicine flies and is adhered on the capsule can be avoided, the acting efficiency can be remarkably improved, the quality and output of the capsule can be obviously increased, and the producing cost can be reduced; compared with tablets, the capsule has the advantages that the pellet is small in granularity, hardly influenced by the food delivery frequency of the alimentary canal, and is high in bioavailability; and by adopting the lumbrukinase enteric-coated pellet capsule, the controllability of the quality is improved.

Method for preparing embolism-extinguishing enteric-coated capsule

The invention discloses the preparation method of a medicine anti-plug enteric soluble capsule for curing anemic apoplexy, deficiency of vital energy and blood stasis. The Chinese medicines astragalus root, angelica and rhizoma ligustici wallichii are steeped into ethanol, the ethanol return flows twice, then is filtered; the filtrate is condensed at certain temperature; the dregs of a decoction are decocted in water with Chinese medicine rot of peony, semen persicae and safflower, then the liquid is filtered; the filtrate is condensed, and the concentrated solution is added by ethanol, stirred and standing; a supernatant fluid is given out and is carried on decompression condensation. Two condensates above are mixed and dried, then grinded so that an extractive is obtained; a fresh lumbricus is dried in shade and grinded, then steeped into water, an extract solution is obtained, decentered, condensed, a condensate is obtained, dried in vacuum at a certain temperature then grinded so that a lumbricus extract is obtained; the extract above is mixed with the lumbricus extract, then packed into the enteric soluble capsule. The effective ingredient of the Chinese medicine of the invention is extracted entirely, and the biological activity of the lumbrokinase of the lumbricus is kept so that the curing effect of the medicine is improved.

Low-immunogenicity lumbrukinase, preparation method and application thereof

The invention discloses low-immunogenicity lumbrukinase, a preparation method and application thereof, and belongs to the field of biological pharmacy. The method provided by the invention comprises the following steps of: first, extracting to obtain a lumbrukinase crude product from an earthworm, and then, passing the crude product through an ion exchange column to elute, purifying, colleting a component with fibrinolytic activity, freezing, drying, concentrating, separating a concentrated lumbrukinase solution by using a gel filtration chromatographic column, detecting the fibrinolytic activity by using an agarose-hemaleucin flat band method, collecting a second eluting peak with the fibrinolytic activity, wherein detected by SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electropheresis), the molecular weight of the second eluting peak is 23500-27500 Da; and after the eluting peak is dialyzed, desalted and subjected to low-temperature freeze drying, carrying out molecular modification on the eluting peak by utilizing activated monomethoxy polyethyleneglycol and dextran to obtain the low-immunogenicity lumbrukinase. The lumbrukinase prepared by the invention has the characteristics of low immunogenicity, high enzyme activity and the like, and can be used for the research and the preparation of an antithrombotic drug and a drug for treating or preventing cardiovascular and cerebrovascular diseases.
