Ulwazi olubalulekile lwempahla kanye nokulungiswa kwesisiki senyama eqandisiwe
Isisiki senyama eqandisiwe siyisisetshenziswa esikhethekile sokusika inyama eqandisiwe. Isetshenziswa ezindaweni zokudlela ezinkulu. Inezinga eliphezulu lokusika inyama kanye nokumelana okuhle nokuhuzuka. Lapho usebenza, ngokuvamile kuyadingeka ukuqoqa ngokunembile izinto zokwakha ngokusho kwezingxenye nama-specimens. Ngokuya ngezingxenye ezihlukene kanye nezakhiwo, izinto zokwakha zisezingeni ngokwezidingo. Ulwazi olubalulekile mayelana nezinto zokwakha kanye nokulungisa imi kanje:
1. Indlela yokulungisa izicubu ezincane: Lena indlela esetshenziswa kakhulu. Izicubu ezincane ezikhishwa esilwaneni ngumsiki wenyama eqandisiwe kufanele zifakwe ngokushesha endaweni ewuketshezi ukuze zilungiswe. Ngokuvamile, isilinganiso se-specimen kuya kokulungisa singu-1: 4~20;
2. Indlela yokulungisa umusi: Ngezibonelo ezincane neziwugqinsi, i-osmium acid noma indlela yokulungisa umhwamuko we-formaldehyde ingasetshenziswa. Ngokuhlolwa kwegazi, i-osmium acid noma umhwamuko we-formaldehyde kufanele usetshenziselwe ukulungisa ngaphambi kokoma imihlola yegazi;
3. Uma sisebenzisa isisiki senyama eqandisiwe ukuze sisike, izithako zethu ezivame ukusetshenziswa zingu-10% we-formaldehyde fixative kanye no-95% we-ethanol fixative;
4. Umjovo, indlela yokuhlanganisa i-perfusion: ezinye izithishu zikhulu kakhulu noma uketshezi olulungisayo kunzima ukungena ngaphakathi, noma isitho sonke noma umzimba wesilwane wonke udinga ukulungiswa;
5. Ukusebenzisa ukulungiswa komjovo noma ukulungiswa kwe-perfusion, ukulungiswa kujovwa emthanjeni wegazi, futhi amagatsha esitsha segazi kuwo wonke amathishu kanye nomzimba wonke, ngaleyo ndlela athole ukulungiswa okwanele.
Ukufingqa, ukukhethwa nokulungiswa kwezisiki zenyama eqandisiwe kudingeka kulandele izidingo ezithile. Izingxenye ezahlukene zinezidingo ezahlukene. Izindlela zokulungisa ezihlukene zidinga izinto ezahlukene kanye nezinzuzo zemvelo. Ngokufanayo, ngokusho kohlobo lwezinto ezibonakalayo kanye nobukhulu benyama efriziwe okufanele inqunywe, impahla ingathathwa futhi ilungiswe.
