Manufacture Specification

The choice of specimen is very important, it has great relation to
improving the quality of the producer. The choice of the
requirements is not stereotyped, must be due to material system,
according to teaching, scientific research, pathological
examination and other purposes. The principle of the specimen
selection is: (1) Accurate selection: Material can not be the
illusion of confusion is particularly important. If the need to
make wheat rust fungus, rice blast slices, should not be caused by
other causes of the spots as rust fungus; Medical staff should also
choose the pathological examination of the reliable part, so that
the mirror can get accurate conclusions. Conversely, if the normal
tissues need to be observed, then the pathological, deformed
specimens can not be selected materials.

(2) Sampling typical: Selecting specimens with typical structure
and paying more attention in teaching. The inclusion of a variety
of Shama although there are transport tissues, but if you observe
the screen, screen plate, with a more suitable pumpkin stems; if
you observe the hepatic lobule, British liver is taken from the pig
livers; if the cochlear structure is observed, guinea pigs are not
only easy to draw, but the cochlea is large, the temporal In
addition, pay attention to the old and old specimens, like plant
roots, stems, leaves, if too young, because of insufficient lignin,
with the red-solid green double staining, not only can not dye red,
instead, it is confused with phloem, thin-walled tissues, and all
is solid green to cover. Of course, if the specimen is too old,
then wood, thick-walled tissue prone to brittle cracking, sometimes
even with the softening process, but to the cutting, wax tablets
will inevitably break, the courseware selection of the appropriate
old specimens is very important.

(3) The selection of specimens should be fresh, if the internal
structure of erosion, production observation will affect the
integrity of the specimen structure. In addition, in the teaching
experiment, we should also pay attention to the selection of
suitable size specimens, such as renal longitudinal slices, using
the white rat, mice as materials, can observe the entire kidney
slice. Conversely, if the huge pig kidney, regardless of the
longitudinal cut, all to be placed on a small piece of glass
slides, this is powerless.

(4) Timely: animal, plant growth and development is regular, select
specimens should pay attention to the season. Studies of animal
chromosomes, many male testes in addition to a certain season, do
not carry out meiosis; study plant chromosomes, commonly used
pollen mother cells, if missed the season is one without income. As
to how to judge the meiosis period according to the shape and size
of the bud, it can be used to keep the experience of the press.

(5) Cleaning: A variety of plants are mostly grown in the soil, so
the selection of roots, stems, leaves, to use a brush to gently
wash the sediment in water, and for example with 1.5% agar feeding
earthworms, two or three days, the sediment can be discharged in
the digestive tract, otherwise hinder the later wax block cutting.
