Abstract
The present invention provides a set of embryo positioning and serial section embedding methods suitable for fertilized eggs of sea water left-eyed flounders and right-eyed flounders, which relates to a microscopic tissue section technology. Aiming at the characteristics that fertilized eggs of sea water left-eyed flounders and right-eyed flounders are polylecithal pelagic eggs with high egg membrane toughness and narrow perivitelline space, the present invention explores and establishes a set of effective tissue section methods aiming at the fertilized eggs of sea water left-eyed flounders and right-eyed flounders. The set of tissue section methods comprises: (1), fixing a polylecithal pelagic egg by Bouin's fixing liquid, and optimizing processing time; (2), poking the egg membrane from the direction of the vegetative pole by a dissecting needle to solve the difficult problem that the egg membrane can not be stripped because of narrow perivitelline space; (3), positioning an embryo by a heat agar directly embedding method. The set of the methods of the present invention has the advantages of simplicity, effectiveness and easy mastery, is suitable for the fertilized egg tissue sections of sea water left-eyed flounders and right-eyed flounders, and is also suitable for the egg tissue sections of other congeneric sea water fish having polylecithal pelagic eggs.
Description
Technical field
The present invention relates to the microstructure microtomy, an a kind of specifically cover embryo location embedding serial section method that is applicable to the seawater left-eyed flounder zygote.
Technical background
In existing section report at fish-egg, material therefor is the fresh water fish-egg, for example grass carp and crucian, and the histotomy of seawater fish fish-egg is not seen report as yet.To the fresh water fish-egg is that it is used Bouin ' s immobile liquid or the fixing back of Smith immobile liquid striping, carries out the dehydration of ethanol gradient by ordinary student fabric texture dicing method, after the dimethylbenzene transparent processing, does specimens paraffin embedding slices.
But the histotomy that utilizes this method to carry out seawater bastard halibut and plaice ovum but is easy to chopping, can not obtain whole slices.Its chief reason is that bastard halibut and plaice ovum and other most of fresh water fish-eggs are different, they are the same with most of seawater fish-eggs to be transparent buoyant egg, yolk is very abundant, the egg membrane that the periphery flexible is stronger, it is narrow and small hardly as seen to compare all cracks of its ovum with most of fresh water fish-eggs through the ovum after fixing the processing, be difficult to complete striping, so the method that the application striping is handled does not again have feasibility in seawater bastard halibut and plaice ovum section experiment.
Summary of the invention
Can not be applied to the weak point that seawater left-eyed flounder ovum is cut into slices at common biology and freshwater fish embryonated egg tissue section method, the present invention comprises the screening of method and the optimization and the repeated experiments of condition through a series of experiment, and the material that is applicable to the section of seawater left-eyed flounder ovum of having set up a whole set of is fixed, processing and tissue section method.
Technical scheme of the present invention is:
1) material is fixed: fish-egg is put into 50～100 times of volume Bouin ' s immobile liquids and is fixed, and fish-egg washes repeatedly with 70% ethanol after Bouin ' s immobile liquid is fixed 6～12 hours, and changes for several times, with the flush away immobile liquid, and preservation, standby in 70% ethanol.
2) material pre-service: after washing ossphere repeatedly and change for several times with 70% ethanol, poke egg membrane with dissecting needle near the plant pole of fish-egg, attention can not damage animal pole.
3) agar location embedding: ovum is placed on the microslide, drip and go up warm agaropectin, natural cooling becomes agar block, adjusts the position of ovum with dissecting needle under anatomical lens, agar concentration 1～2%.
4) processed: handle through 70%, 80%, 90%, 95%, 100% gradient alcohol dehydration, per step is handled 30～60min, adds Yihong in 95% ethanol ossphere is dyed redness, observes its position when making things convenient for the later stage section.
5) transparent processing: with terpinol agar block is carried out transparent processing, agar block is immersed in the terpinol, the processing time judges that according to the size and the transparent situation of agar block need more than 4 hours, generally at 4～12 hours, time expand had no adverse effects.
6) saturating wax is handled: mix the liquid processing more than 4 hours through terpinol and paraffin equal-volume, generally at 4～12 hours, can put into paraffin, paraffin infiltration totally four times is handled more than 1 hour, generally at 1～4 hour at every turn.
7) paraffin embedding: can carry out embedding after saturating wax is finished, make paraffin mass.
8) carry out histotomy, the section that obtains is carried out haematine Yihong (H.E) dyeing after paster, roasting sheet are handled, dyeing back cinephotomicrography is observed and is taken pictures.
Advantage of the present invention and good effect are:
1. the present invention has set up suitable seawater fish buoyant egg fixing method and condition, be many yolk buoyant egg, contain oily ball, egg membrane toughness is strong and all cracks of ovum are narrow and small characteristics at the seawater left-eyed flounder zygote, explore and set up the effective tissue section method that a cover is applicable to the seawater left-eyed flounder zygote.There is report to think use the fixing many yolk fish-egg of Bouin ' s immobile liquid to cause the crisp hard of yolk easily and causes section to be failed, and should fix with the Smith immobile liquid.But our fixedly processing time gradient experiment showed, fish-egg and fixes 6～12 hours through Bouin ' s immobile liquid that crisp hard phenomenon can not take place yolk, cuts into slices normally, can avoid numerous and diverse operation steps of using the Smith immobile liquid to bring.
2. the invention solves the problem that ovum can not dewater fully.Because egg membrane is tough and tensile and fine and close, serious shrinkage takes place in the effect egg membrane because of osmotic pressure when making the ovum dehydration, cause the section failure, the general method that divests egg membrane that adopts solves, but the ovum of flounder flounder class can't be removed egg membrane with dissecting needle through the crack is narrow and small the fixing back of Bouin ' s immobile liquid ovum week, and the present invention is then by this difficult point of solution of punching on egg membrane with dissecting needle.
3. the invention solves the orientation problem of ovum.With agar ovum is carried out the existing precedent in embedding in advance location, method is the agar that solidifies to be burnt duck eye put into reusable heat agar embedding behind the ovum, and the present invention is improved this, with the direct agar embedding of ovum, has avoided the agar layering to cause the section failure.
4. the present invention is applied to obtain complete histotomy, respond well repeatability high (seeing accompanying drawing 1-3) in the histotomy experiment of lefteye flounder and turbot fertilized eggs.Therefore the present invention is applicable to the histotomy of bastard halibut and plaice ovum.
5, the inventive method is simply effective, grasps easily, not only is applicable to seawater left-eyed flounder zygote histotomy, is applicable to that also its scope of application is extensive in the ovum histotomy that belongs to buoyant egg, megalecithal other seawater fish together.
