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.
