Description
Technical field
The present invention relates to the cultural technique of a kind of Chinese medicine animal drug, a kind of blood-eating hirudo adult is raised
Feed and the sustainable extracting method of hirudin and special equipment.
Technical background
Blood-eating hirudo (formal name used at school: Hirudo nipponia) be Yi Zhi section doctor trematodiasis belong to animal, popular name hirudo nipponica, Hirudo,
Line Hirudo, Hirudo, Japan doctor Hirudo.Be distributed in the Far East Area Japanese, Muscovite, Mongolia and China's Mainland North gets northeast
Each province, the Inner Mongol, west to Sichuan, Gansu, south reach the ground such as Guangdong, typically inhabit paddy field and the irrigation canals and ditches communicated therewith, pond
Most with quantity in hydrops in marsh and particularly throughout the year or the waterlogged plot of impeded drainage and field heart.
Hirudin (Hirudin) is to have extracted various active in Hirudo (Leech) or blood-eating hirudo and salivary gland thereof
A kind of composition that in point, activity is the most notable and most studied, the small protein that it is made up of 65-66 aminoacid
(polypeptide).Hirudo contains abundant hirudin, and hirudin has extremely strong inhibitory action to thrombin, is to be found up to now
The natural specific inhibitor of strong thrombin.Animal experiment shows with clinical research, hirudin energy Effective Anti blood coagulation, antithrombotic shape
Become, and stop the blood stasis phenomenon further such as thrombin activation and platelet response of catalyzed by thrombin.Additionally, it can also press down
Fibroblastic propagation of thrombin induction processed and the stimulation of thrombin Human Umbilical Vein Endothelial Cells.Compared with heparin, its not only consumption
Few, will not cause bleeding, also not dependent on endogenous co-factor；Heparin then has the danger caused bleeding, at diffusivity blood
In the pathogenic process of intravascular coagulation, antithrombin Ⅲ often reduces, and this will limit the curative effect of heparin, uses Hirudo to have preferably
Effect.The method proposing hirudin at present from blood-eating hirudo is directly to be put to death by blood-eating hirudo, directly extracts in polypide；Need
Want substantial amounts of Hirudo adult resource.
Summary of the invention
The invention provides a kind of blood-eating hirudo adult for solution the problems referred to above to feed and the sustainable extracting method of hirudin,
Comprise the following steps:
1) under 25-29 DEG C of environmental condition, adult blood-eating hirudo is carried out concentration and feeds, after feeding end, clear up feedstuff

2) blood-eating hirudo after feeding was 22-25 DEG C of fasting 15-20 days；
3) under 25-29 DEG C of environmental condition, concentrate the blood-eating hirudo after fasting, clean with the normal saline of 0.6-0.8%
After, blood-eating hirudo is placed in container, induces liquid to blood-eating hirudo fed to appetite, and clean again with the normal saline of 0.6-0.8%
Clean；
4) it is formulated with zinc sulfate, acetic acid and the emetic liquid of water composition, blood-eating hirudo is laid in special container, according to day
This doctor trematodiasis weight adds emetic liquid with the ratio of emetic liquid weight ratio 1:1；
5) blood-eating hirudo is carried out ultraviolet light radiation-induced 2-3 time, each 10-15min, each induction interval 10-
15min；
6), after radiation-induced terminates, clean blood-eating hirudo with the normal saline of spray 0.6-0.8%, and collect rinse water liquid
As hirudin extracting solution；
7) after hirudin extracting solution adds stabilizer, it is spray-dried, obtains hirudin crude extract；
8), after the blood-eating hirudo after cleaning continues to raise 1 month, step 1 is repeated)-7) persistently extract hirudin.
Step 2) described in induction liquid be fresh and alive Monopteri albi extract and glucose mixing aqueous solution.
Stabilizer described in step 7 be the weight ratio of the mixture of starch and chitosan, starch and chitosan be 10:2.
A kind of special equipment of the blood-eating hirudo sustainable extraction of adult hirudin, described special equipment by urceolus, inner core and
Ultraviolet source is constituted；
Wherein, urceolus is box like structure or the barrel-like structure of upper opening, urceolus be provided above bracing frame urceolus
Bottom is provided with the valve for draining；Inner core is arranged at the inner side of urceolus, and inner core is box like structure or the tubbiness of upper opening
Structure, the bottom of inner core (2) is that filtering bottom board is constituted, and filtering bottom board is sieve plate or the screen cloth of aperture 20-100 mesh, and inner core connects
It is connected to hook；Outer light source is arranged on urceolus and the top of inner core upper opening.
The method have the benefit that: a kind of method that sustainable offer hirudin is provided, save
The resource of blood-eating hirudo, what the present invention provided simultaneously extracts emetic can increase the single yield of hirudin, has significantly
Economic benefit.
