Relevant knowledge of material and fixation of jarjar hilib barafaysan

1. Habka hagaajinta unugyada yaryar: Tani waa hab caadi ah oo la isticmaalo. Nudaha yar ee laga soo saaray neefka ee uu jarjaray hilibka barafaysan waa in isla markiiba la geliyo dareeraha hagaajinta si loo hagaajiyo. Caadi ahaan, saamiga muunada iyo hagaajinta waa 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. Markaad isticmaalayso jarjar hilib barafaysan si aad u jarjarto, hagaajinteena inta badan la isticmaalo waa 10% formaldehyde fixative iyo 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.

Si loo soo koobo, xulashada iyo hagaajinta jeexjeexyada hilibka barafaysan waxay u baahan yihiin inay raacaan shuruudaha qaarkood. Qaybaha kala duwan waxay leeyihiin shuruudo kala duwan. Hababka kala duwan ee hagaajinta waxay u baahan yihiin qalab kala duwan iyo faa’iidooyin dabiici ah. Sidoo kale, marka loo eego nooca walxaha iyo dhumucda hilibka barafaysan ee la jarjaray, walxaha waa la qaadi karaa oo la hagaajin karaa.
