Ruzivo rwakakodzera rwezvinhu uye kugadzirisa kwechando chekucheka nyama
Relevant knowledge of material and fixation of chando chekucheka nyama
1. Nzira yekugadzirisa zvinyama zviduku: Iyi inzira inowanzoshandiswa. Iyo matishu madiki anobviswa kubva kumhuka neyakaomeswa nyama inocheka inofanira kuiswa pakarepo mune yemvura inogadzirisa kugadzirisa. Kazhinji, chiyero chemuenzaniso kune kugadzirisa ndeye 1: 4~20;
2. Steam fixation method: For relatively small and thick specimens, osmium acid or formaldehyde vapor fixation method can be used. For blood smears, osmium acid or formaldehyde vapor should be used to fix the blood before drying;
3. Paunenge uchishandisa nyama yakaomeswa slicer yekucheka, yedu inowanzoshandiswa kugadzirisa ndeye 10% formaldehyde fixative uye 95% ethanol fixative;
4. Injection and perfusion fixation method: some tissue blocks are too large or the fixative is difficult to penetrate into the interior, or the entire organ or the entire animal body needs to be fixed;
5. Adopt injection fixation or perfusion fixation method to inject the fixative into the blood vessel and reach the whole tissue and the whole body through the branch of the blood vessel, so as to obtain sufficient fixation.
Kupfupisa, kusarudzwa uye kugadzirisa kwechando chekucheka nyama kunoda kutevedzera zvimwe zvinodiwa. Zvikamu zvakasiyana zvine zvinodiwa zvakasiyana. Nzira dzakasiyana dzekugadzirisa dzinoda zvinhu zvakasiyana-siyana uye mabhenefiti echisikigo. Saizvozvo, zvinoenderana nerudzi rwezvinhu uye kuwanda kwenyama yakaomeswa kuti ichekwe, zvinhu zvacho zvinogona kutorwa nekugadziriswa.
