Embodiment 1

[0085] The preparation method of embodiment 1 lumbrokinase dry powder (1)

[0086] 1) Earthworm cleaning: After washing 10 kg of live open-air red worms with water, add 0.2 kg of cotton white sugar per kg of earthworms, stir evenly at room temperature, and let it stand for 40 minutes to stimulate the earthworms to excrete the secretions in their digestive tracts. Spit it out, and then wash off the sugar and dirt on the earthworms with warm water at 30°C;

[0087] 2) Pulping: add water of 1 times the volume of the earthworm, and use a high-pressure homogenizer to crush the earthworms cleaned in step 1) to make a homogenate;

[0088] 3) slag removal: the homogenate obtained in step 2) is filtered through a stainless steel filter with a screen aperture of 5 mm to remove the coarse slag in the homogenate;

[0089] 4) clarification: after step 3) the homogenate liquid after deslagging is processed by a high-speed centrifuge to obtain a clarified liquid;

[0090] 5) Separation: us...

Embodiment 2

[0095] The preparation method of embodiment 2 lumbrokinase dry powder (2)

[0096] Cleaning: After washing 10 kg of live open-air red worms with water, add sodium chloride at a rate of 0.3 kg of sodium chloride per kg of earthworms, stir evenly at room temperature and let stand for 40 minutes to stimulate the earthworms to excrete Spit out the secretions, and then wash off the sugar and dirt on the earthworms with warm water at 40°C.

[0097] Pulping: crush the earthworms with a bead mill, add water (the amount of water added is 8 times the volume of the earthworms) to make a homogenate; make a homogenate.

[0098] Removal of slag: Use a centrifuge to remove the coarse slag in the homogenate, and then process the homogenate after deslagging with a high-speed centrifuge to obtain a clarified liquid.

[0099] Separation: Use an ion exchange chromatography column to separate the earthworm clarified liquid, elute with 0.01M acetate, collect the active peak part of the chromatogra...

Embodiment 3

[0104] The preparation method of embodiment 3 lumbrokinase dry powder (3)

[0105] Cleaning: After washing 10 kg of live open-air red worms with water, add cotton white sugar at a rate of 0.1 kg of sugar per kg of earthworms, stir evenly at room temperature and let stand for 40 minutes to stimulate the earthworms to excrete the secretions in their digestive tracts Spit it out, and then wash off the sugar and dirt on the earthworms with warm water at 30°C.

[0106] Pulping: Crush the earthworms with a high-pressure homogenizer, add water to make a homogenate.

[0107] Removal of slag: Use a stainless steel filter with a pore size of 2 mm to filter out the coarse slag in the homogenate, and then process the homogenate after deslagging with a high-speed centrifuge to obtain a clarified liquid.

[0108] Separation: Use an affinity chromatography column to separate the earthworm clarified liquid, elute with 0.5M acetate, collect the active peak part of the chromatographic effluent...

Abstract

The invention provides lumbrukinase and application thereof for preparing a medicament treating carotid atherosclerosis and a medicament containing the lumbrukinase as an active component.

Description

field of invention [0001] The invention belongs to the field of biotechnology, and in particular relates to the application of lumbrokinase in the preparation of drugs for treating carotid atherosclerosis. Background of the invention [0002] Atherosclerosis (AS) is a general term for several diseases in which the arterial wall thickens and loses elasticity, and is the most common and important type of arteriosclerosis. The main lesion feature of atherosclerosis is the subintimal lipid deposition in some parts of the artery, accompanied by the proliferation of smooth muscle cells and fibrous matrix components, and gradually develops into atherosclerotic plaque. [0003] It is a lesion characterized by patchy subintimal thickening (atheroma) of medium and large arteries that reduces or blocks blood flow, thickening and hardening of the arterial wall at the site of the plaque, and After tissue necrosis, it combines with deposited lipids to form atherosclerosis, which is calle...
