Malinga ndi zotsatira za kafukufuku wa mabungwe odziwika padziko lonse lapansi, matenda ndi ukalamba wa thupi la munthu zimayamba chifukwa cha kuwonongeka kwa maselo. Mphamvu ya maselo yodzikonzanso yokha imachepa ndi kukula kwa ukalamba. Pamene maselo okalamba ndi odwala akupitiriza kusonkhana, maselo atsopano sangawalowe m'malo mwawo pakapita nthawi, ndipo matenda ndi ukalamba zimabuka mosalephera.
Maselo oyambira ndi mtundu wapadera wa selo m'thupi womwe ungasanduke mtundu uliwonse wa selo m'thupi lathu, womwe umagwiritsidwa ntchito kukonza zowonongeka ndikulowa m'malo mwa maselo okalamba. M'zaka zaposachedwa, ndi kuzama kwa lingaliro la chithandizo cha maselo oyambira matenda ndi mphamvu yoletsa ukalamba, kusungidwa kwa maselo oyambira kwakhala chisankho chofunikira kwambiri pa thanzi la anthu ambiri mtsogolo.
Nthawi Yosungira Maselo Oyambira mu Dongosolo la Nayitrogeni Yamadzimadzi
Mwa chiphunzitso, kusungira madzi a nayitrogeni kumatha kusunga zinthu za maselo kwamuyaya. Pakadali pano, chitsanzo cha maselo chodziwika bwino chomwe chasungidwa kwa nthawi yayitali mu labotale ya Chinese Academy of Sciences chasungidwa kwa zaka 70. Izi sizikutanthauza kuti kusungirako kozizira kungachitike kwa zaka 70 zokha, koma chitukuko cha makampani onse chili ndi mbiri ya zaka 70 zokha. Ndi chitukuko cha The Times, nthawi ya maselo oyambira ozizira idzakulitsidwa mosalekeza.
Zachidziwikire, nthawi yosungira cryopreservation imadalira kutentha kwa cryopreservation, chifukwa cryopreservation yozama yokha ndi yomwe ingapangitse maselo kukhala chete. Nthawi zonse, imatha kusungidwa kwa maola 5 kutentha kwa chipinda. Kutentha kochepa madigiri 8 Celsius kumatha kusungidwa kwa maola 48. Mafiriji otsika kutentha -80 digiri Celsius amatha kusungidwa kwa mwezi umodzi. Nayitrogeni wamadzimadzi ndi wokhazikika pa -196 digiri Celsius.
Mu 2011, zotsatira za kafukufuku wa in vitro ndi nyama zomwe zinafalitsidwa mu Blood ndi Pulofesa Broxmeyer ndi gulu lake ochokera ku Indiana University, yomwe ndi katswiri pa kafukufuku wa biology ya maselo oyambira a chingwe cha BLOOD, zinatsimikizira kuti maselo oyambira omwe asungidwa kwa zaka 23.5 akhoza kusunga mphamvu zawo zoyambirira za kuchulukana, kusiyanitsa, kukula komanso kuyika mu vivo.
Mu 2018, selo loyambira lomwe linasonkhanitsidwa ku Beijing Obstetrics and Gynecology Hospital linazizira kwa zaka 20 ndi miyezi 4 mu June 1998. Pambuyo pobwezeretsa maselo, ntchitoyo inali 99.75%!
Pakadali pano, pali mabanki opitilira 300 a magazi padziko lonse lapansi, ndipo 40 peresenti ku Europe, 30 peresenti ku North America, 20 peresenti ku Asia ndi 10 peresenti ku Oceania.
Bungwe la World Marrow Donor Association (WMDA) linakhazikitsidwa mu 1994 ndipo lili ku Leiden, Netherlands. Lalikulu kwambiri ndi National Marrow Donor Program (NMDP), lomwe lili ku Minneapolis, Minn., ndipo linakhazikitsidwa mu 1986. DKMS ili ndi opereka ndalama pafupifupi 4 miliyoni, omwe amapereka oposa 4,000 chaka chilichonse. Pulogalamu ya Chinese Marrow Donor Program (CMDP), yomwe idakhazikitsidwa mu 1992, ndi banki yachinayi yayikulu kwambiri ya marrow pambuyo pa United States, Germany ndi Brazil. Amatha kusiyanitsa mitundu ina ya maselo amagazi, monga maselo ofiira amagazi, maselo oyera amagazi, ma platelet ndi zina zotero.
Dongosolo la Nayitrogeni Yamadzimadzi Yosungira Maselo Oyambira
Dongosolo losungira maselo oyambira limapangidwa makamaka ndi thanki yayikulu yamadzimadzi ya nayitrogeni, gulu la mapaipi opangidwa ndi vacuum jacketed (kuphatikiza chitoliro chopangidwa ndi vacuum jacketed, payipi yopangidwa ndi vacuum jacketed, gawo lolekanitsa, valavu yoyimitsa ya vacuum jacketed, chotchinga cha mpweya, ndi zina zotero) ndi chidebe chachilengedwe chosungira zitsanzo za maselo oyambira mu thanki.
Nayitrogeni yamadzimadzi imapereka chitetezo chotsika kutentha nthawi zonse m'zidebe zamoyo. Chifukwa cha mpweya wachilengedwe wa nayitrogeni yamadzimadzi, nthawi zambiri pamafunika kudzaza zidebe zamoyo kamodzi pa sabata kuti kutentha mu chidebe chamoyo kukhale kotsika mokwanira.
Zipangizo za HL Cryogenic
Kampani ya HL Cryogenic Equipment yomwe idakhazikitsidwa mu 1992 ndi kampani yogwirizana ndi kampani ya Chengdu Holy Cryogenic Equipment ku China. Kampani ya HL Cryogenic Equipment yadzipereka pakupanga ndi kupanga High Vacuum Insulated Cryogenic Piping System ndi zida zina zothandizira.
