Abstract
Cranium method is opened the invention discloses a kind of complete sheep brain of acquisition, it is comprised the following steps:Remove complete sheepshead;A line, each line at the 2cm of left and right ear lower section are cut backward along calvarium center line in cutting skin line, a horizontal line at 2cm before goat's horn, longitudinal direction;Use excision 1cm skins wide along scalpel;Fixed sheepshead, is directed at each bar line and is cut using Arm saw, and depth of cut is 1cm or so;Chisel insertion cranium is determined into transverse cuts gap, by lever principle, cranium is opened;After complete exposure sheep brain, sheep brain is lifted slightly, using scalpel, progressively cut from front to back, obtain complete sheep brain;Ephippium cartilage is cut using scalpel, complete hypophysis is obtained.Cranium method is opened using of the invention, complete sheep brain and each organ-tissue of encephalic can be obtained, complete material is provided to make sample, with certain economic value;Simultaneously for scientific research provides excellent material.
Description
Technical field
The present invention relates to bioscience technology field, be specifically related to a kind of complete sheep brain of acquisition opens cranium method.
Background technology
Sheep is very important domestic animal, is one of main sources of physical resources such as our meat, hair, milk.The life of sheep
Long and development is closely related with hormone, but most of hormone both is from intracerebral, such as growth hormone.In scientific research process
In, in order to probe into the generation and metabolism of intracerebral hormone, it is necessary to obtain the complete tissue of intracerebral.Such as breeding and the rush of hypothalamus secretion
Gonadotropin releasing hormone is closely related, in order to study hypothalamus regulation and control gonadotropin-releasing hormone (GRH) mechanism of secretion, Wo Menbi
Complete inferior colliculus cerebral tissue must be obtained.Intracerebral also has some special samples such as hypophysis, pineal body to be also required to obtaining complete sheep
Could be obtained on the premise of brain.So how cleverly to open cranium, obtain complete tissue has very big value to scientific research.
On the other hand, during intracerebral sample is made, complete tissue, sample is also usually needed to have economic valency as commodity
Value, so obtaining complete sheep brain opens the method for cranium also with certain economic worth.
The method and technology that cranium performed the operation to be opened for people many at present, but the structure of sheep and people is completely different, and sheep
Or even many animals all do not have systematic method for opening cranium, so the cranium method of opening that we develop has novelty and advanced
Property.
The content of the invention
Present invention solves the technical problem that be, in view of the shortcomings of the prior art, there is provided it is a kind of obtain complete sheep brain open cranium
Method.
Technical scheme is as follows:
It is a kind of obtain complete sheep brain open cranium method, comprise the following steps:
S1:After butchering goat, in removing complete sheepshead in 1-60min, and with 0.01-12h in carry out out cranium and operate;
S2:Skin is cut using scalpel to rule:(eyes back upper place) cuts one at 2cm before the goat's horn of sheepshead calvarium
X wire, is brain forward position below the position;A vertical line is cut along calvarium center line (toward neck direction) backward in longitudinal direction;Left and right
Ear lower section place each line, respectively left line and right line, the left line and right line on neck obliquely by below ear with
X wire intersects;
S3:Using scalpel and scissors, transversely line, vertical line, left line and right line respectively cut off 1cm skins wide respectively, along
, it is necessary to some meat are cut off when left line and right wire cutting ear lower section;
S4:, can be put in sheepshead on stool by fixed sheepshead, and being directed at each bar line using Arm saw is cut, and cutting is deep
It is 1 ± 0.02cm to spend, preferably 1cm, saw calvarium when it is important to note that, it is impossible to cut through depth;
S5:By chisel insertion calvarium transverse cuts gap, by lever principle, cranium is opened, or to hold goat's horn past
Both sides are exerted oneself, and break sheepshead into two with one's hands;
S6:After complete exposure sheep brain, sheep brain is lifted slightly, using scalpel, progressively cut from front to back, obtain complete
Sheep brain;
S7:By sheep brain in turn, the hypothalamus of " peanut valve " shape is clear that, hypothalamus is careful with small scissors
Cut;
S8:Sheepshead front is put, is cut downwards along brain center line using scalpel, open brain, connected in brain and cerebellum
Position is connect it can be seen that a round bead, the sample is pineal body;
S9:Ephippium cartilage is cut using scalpel, is cut toward both sides as possible, finally take out complete hypophysis with scissors,
The hypophysis of taking-up also with cartilage and film, film and cartilage is carefully removed, and obtains complete pituitary;
S10:Sampling is completed, complete brain tissue, including brain, cerebellum, hypothalamus, pineal body, pituitary is obtained.
Further, in such scheme, after butchering goat, in removing complete sheepshead in 1-20min.
Further, in such scheme, after removing complete sheepshead, cranium operation is carried out out in 0.01-1h.
Further, in such scheme, at the brain that will remove, cerebellum, hypothalamus, pineal body, pituitary DEPC
After reason water washing, contained with the EP pipes equipped with RNA preservation liquid and preserved.
Alternatively, brain, cerebellum, hypothalamus, pineal body, the solution of the following formulas of pituitary that will be removed
Sealing immersion is preserved:Guanidine hydrochloride 22.15%, ferric pyrophosphate 18.2%, ferrous fumarate 2.88%, dithiothreitol (DTT) 0.328%,
Lysine hydrochloride 0.012%, N- acyl derivatives 0.65%, cryoprotector 2~5%, water add to 100%, and the freezing is protected
Shield agent is dimethyl sulfoxide (DMSO), and storage temperature is arranged on -40~-60 DEG C.
The beneficial effects of the invention are as follows:The present inventor by the careful observation and dissection to goat head construction,
Determine the location of skeletal structure, sheep brain of sheepshead, each bone tie point of sheepshead, formulate a set of acquisition complete brain tissue of sheep
Open cranium method, the method has certain systematicness, simple to operate, it is ensured that brain tissue is not destroyed, so that it is complete to obtain intracerebral
Whole tissue, including brain, cerebellum, hypothalamus, hypophysis, pineal body, not only facilitate scientific research, and making intracerebral mark
Present aspect has certain economic worth.
