Zvichienderana nemhedzisiro yekutsvagisa kwemasangano ane masimba pasi rose, zvirwere nekuchembera kwemuviri wemunhu zvinotanga nekukuvadzwa kwemasero. Kugona kwemasero kuzvivandudza pachawo kunoderera nekuwedzera kwekukwegura. Kana kukwegura uye masero ane chirwere zvichiramba zvichiungana, masero matsva haagone kuatsiva nekufamba kwenguva, uye zvirwere nekuchembera zvinongoitika.
Masero emuviri imhando yakakosha yesero mumuviri inogona kushanduka kuita chero rudzi rwesero mumuviri wedu, rinoshandiswa kugadzirisa kukuvara nekutsiva masero ekukwegura. Mumakore achangopfuura, nekuwedzera kwepfungwa yekurapa masero emuviri ezvirwere uye kudzivirira kukwegura, kuchengetedza masero emuviri kwave sarudzo yakakosha kune hutano hwevanhu vazhinji mune ramangwana.
Nguva Yekuchengetera Masero Emuviri MuLiquid Nitrogen System
Panyaya yedzidziso, kuchengetedza nitrogen yemvura kunogona kuchengetedza zviwanikwa zvemasero nekusingaperi. Parizvino, sample yemasero yakachengetedzwa kwenguva refu murabhoritari yeChinese Academy of Sciences yakachengetwa kwemakore makumi manomwe. Izvi hazvirevi kuti kuchengetwa kwechando kunogona kuitwa kwemakore makumi manomwe chete, asi kukura kweindasitiri yese kune nhoroondo yemakore makumi manomwe chete. Nekuvandudzwa kweThe Times, nguva yemasero echando icharamba ichiwedzerwa.
Ehe, nguva yekucheneswa kwemasero inoenderana nekupisa kwemasero, sezvo kuchenesa kwakadzika chete ndiko kunogona kuita kuti masero ararame. Mumamiriro ezvinhu akajairwa, inogona kuchengetwa kwemaawa mashanu patembiricha yemumba. Tembiricha yakaderera ye8 degrees Celsius inogona kuchengetwa kwemaawa makumi mana nemasere. Mafiriji ekupisa kwakadzika -80 degrees Celsius anogona kuchengetwa kwemwedzi. Nitrogen yemvura inogara iripo pa -196 degrees Celsius.
Muna 2011, mhedzisiro yekuedza kwe in vitro nemhuka yakaburitswa muBlood naProfessor Broxmeyer nechikwata chake kubva kuIndiana University, iyo inyanzvi mukutsvagisa kwe cord BLOOD stem cell biology, yakaratidza kuti masero e stem akachengetwa kwemakore 23.5 anogona kuchengetedza kugona kwawo kwekutanga kwekuwedzera, kusiyanisa, kuwedzera uye kuiswa mu vivo.
Muna 2018, stem cell yakaunganidzwa muBeijing Obstetrics and Gynecology Hospital yakaomeswa nechando kwemakore makumi maviri nemwedzi mina muna Chikumi 1998. Mushure mekudzorerwa mumuviri, chiitiko chacho chaive 99.75%!
Kusvika pari zvino, kune mabhangi eropa etambo anopfuura mazana matatu pasi rose, 40 muzana iri muEurope, 30 muzana iri muNorth America, 20 muzana iri muAsia uye 10 muzana iri muOceania.
Sangano reWorld Marrow Donor Association (WMDA) rakavambwa muna 1994 uye riri muLeiden, Netherlands. Guru ndiro National Marrow Donor Program (NMDP), riri muMinneapolis, Minn., uye rakavambwa muna 1986. DKMS ine vanopa mari vanosvika mamiriyoni mana, vachipa vanodarika 4,000 gore rega rega. Chirongwa cheChinese Marrow Donor Program (CMDP), chakavambwa muna 1992, ndicho bhangi rechina guru remarrow mushure meUnited States, Germany neBrazil. Vanogona kusiyana kuita mamwe marudzi emasero eropa, akadai semasero matsvuku eropa, masero machena eropa, maplatelet nezvimwewo.
Sisitimu yeNitrogen yeLiquid yekuchengetedza masero eStem
Sisitimu yekuchengetera masero esimbi inonyanya kuve netangi hombe remvura rine nitrogen cryogenic, seti yemasisitimu emapaipi ane vacuum jacketed (kusanganisira pombi ine vacuum jacketed, hose ine vacuum jacketed, phase separator, vacuum jacketed stop valve, air-liquid barrier, nezvimwewo) uye mudziyo webiological wekuchengetera sampuro dzemasero esimbi mutangi.
Nitrogen yemvura inopa dziviriro isingaperi pakupisa kwakaderera mumidziyo yehupenyu. Nekuda kwekuwedzera gasi remvura yenitrogen, zvinowanzo dikanwa kuzadza midziyo yehupenyu kamwe chete pasvondo kuitira kuti tembiricha iri mumidziyo yehupenyu ive yakaderera zvakakwana.
Midziyo yeHL Cryogenic
Kambani yeHL Cryogenic Equipment yakavambwa muna 1992 ikambani yakabatana neChengdu Holy Cryogenic Equipment Company muChina. HL Cryogenic Equipment yakazvipira mukugadzira nekugadzira High Vacuum Insulated Cryogenic Piping System pamwe nemidziyo yekutsigira yakabatana nayo.
