Kodi mudamvapo za khansa ya muubongo? Ndi vuto loopsa kwambiri komanso lovuta kuchiza. Chifukwa ubongo wathu ndi malo otetezeka kwambiri m'thupi. Si chilichonse chomwe chingalowe mosavuta mmenemo. Chifukwa cha chitetezochi, ngakhale mankhwala omwe amagwiritsidwa ntchito pa khansa (chemotherapy) sangafikire maselo a khansa muubongo. Koma tsopano asayansi apeza yankho lodabwitsa pa izi.
Kodi chotchinga cha magazi ndi ubongo ichi n'chiyani?
Mwachidule, izi zili ngati khoma lotetezeka kwambiri lozungulira ubongo wathu. Tangoganizani kuti ubongo wathu ndiye nyumba yofunika kwambiri komanso yotetezeka kwambiri m'dzikolo. Khomo lolowera m'nyumba imeneyo limadutsa pachipata cholimba kwambiri. Chipata ichi chimaletsa majeremusi ndi mankhwala osafunikira m'magazi athu kuti asalowe muubongo. Ichi ndi chomwe timachitcha kuti Blood-Brain Barrier mu zamankhwala.
Chitetezo ichi n'chofunika kwambiri kwa ife. Koma vuto ndilakuti, chitetezochi chimaona ngakhale mankhwala a chemotherapy ngati 'alendo osafunikira' ndipo sichimalola kuti alowe. Chifukwa chake, kuchiza khansa ya muubongo kwakhala vuto lalikulu kwa madokotala.
Yankho laposachedwa la asayansi: Kachidutswa kakang'ono kamene kamasungunuka!
Gulu la asayansi tsopano lapeza njira yatsopano yothetsera vutoli: kachidutswa kakang'ono kamene kamasungunuka m'thupi ndipo kamayikidwa mkati mwa chigaza, pafupi ndi komwe khansa ya muubongo ili.
Chida ichi chaching'ono, chomwe chili ndi bokosi laling'ono pafupifupi sentimita imodzi mulifupi, chimapangidwa ndi amino acid yapadera. Chimatchedwa glycine . Chapadera ndichakuti magetsi ang'onoang'ono akagwiritsidwa ntchito, amanjenjemera ndi kutulutsa mafunde amphamvu kwambiri, kapena mafunde a ultrasound , omwe samveka m'khutu la munthu. Njirayi imatchedwa piezoelectric effect .
Tsopano taganizirani kuti dokotalayo wabaya mankhwala oletsa khansa, monga paclitaxel, m'thupi. Nthawi yomweyo, chipangizo cholamulidwa ndi kunja chimapereka magetsi ku choyikamo chaching'ono muubongo. Kenako, mafunde a ultrasound omwe amatuluka nawo amachititsa kuti maselo a Blood-Brain Barrier omwe tidalankhula agwedezeke pang'ono, ndikupanga mipata yaying'ono pakati pawo. Kunena zoona, zili ngati chipata chotsekedwa bwino chikutseguka pang'ono. Kudzera m'mipata imeneyo, mankhwala a khansa amatha kupita mwachindunji ku maselo a khansa. Kodi sizodabwitsa?
Tiyeni tiwone zina mwa zabwino za ukadaulo watsopanowu mu tebulo ili m'munsimu.
| Mbali | Kufotokozera |
|---|---|
| Cholinga | Mankhwalawa amaperekedwa mwachindunji ku maselo a khansa ya muubongo. |
| Chitetezo | Sizimawononga minofu ya ubongo yathanzi. |
| Zinthu Zofunika | Yopangidwa kuchokera ku glycine, yomwe ndi yothandiza kwa thupi. |
| Zowola | Pakapita nthawi, imasungunuka m'thupi popanda kuvulaza. Palibe chifukwa chochitira opaleshoni ina kuti ichotsedwe. |
| Kulamulira | Madokotala amatha kulamulira nthawi yomwe chipangizochi chiyenera kugwira ntchito. |
Kugwiritsa ntchito ukadaulo wa ultrasound m'njira zambiri
Ukadaulo wa ultrasound uwu si watsopano ku chipatala. Nthawi zambiri takhala tikumva za izi pojambula ana. Koma tsopano ukugwiritsidwa ntchito pazinthu zambiri kuposa pamenepo. Malinga ndi Dr. Neal Kassell, m'modzi mwa akatswiri omwe ali ndi ukadaulowu, zili ngati "kugwiritsa ntchito galasi lokulitsa kuti liyang'ane kuwala kwa dzuwa ndikuwotcha tsamba." Izi zikutanthauza kuti mphamvuyo ikhoza kulunjika molondola kwambiri, kokha ku cholinga chomwe mukufuna. Chifukwa chake sichivulaza minofu yathanzi yozungulira.
Madokotala tsopano akudziwa njira zoposa 30 zosiyanasiyana zolumikizirana ndi minofu pogwiritsa ntchito ukadaulo wa ultrasound, poyerekeza ndi njira 5 zokha zaka khumi zapitazo.
Ndi chidziwitso ichi, tikukhulupirira kuti ukadaulo uwu ungagwiritsidwe ntchito pochiza osati khansa ya muubongo yokha, komanso matenda amitsempha monga Alzheimer's ndi Parkinson's, khansa ya kapamba ndi prostate yovuta kuchiza, komanso ngakhale kugwiritsa ntchito mankhwala osokoneza bongo.
Kodi tsogolo la ukadaulo uwu likuwoneka bwanji?
Tiyenera kukumbukira kuti izi zikadali mu gawo lofufuza. Asayansi ayesa izi pa mbewa ndipo awona zotsatira zabwino kwambiri. Atapatsidwa mankhwalawa, zotupazo zinachepa ndipo moyo wa ziwetozo unawirikiza kawiri. Ngakhale patatha miyezi 6, palibe zotsatirapo zoyipa zomwe zanenedwa. Kenako, gululo likukonzekera kuyesa chitetezo chake ndi mphamvu zake mwa nkhumba.
Katswiri wa sayansi yemwe anatulukira izi, Thanh Nguyen, akuyembekeza kupanga chinthu chonga chigamba chokhala ndi zinthu zambiri zazing'onozi mtsogolo. Kenako zidzatheka kulunjika ndikuchiza ziwalo zosiyanasiyana za ubongo nthawi imodzi. Mwina njira iyi ingagwiritsidwe ntchito kuwononga maselo aliwonse otsala a khansa pambuyo poti chotupa cha muubongo chachotsedwa opaleshoni.
Uthenga Wopita Nawo Kunyumba
- Choyikamo cha khansa chomwe chingawole chomwe chafotokozedwa m'nkhaniyi ndi ukadaulo wamakono komanso wodalirika kwambiri pochiza khansa ya muubongo.
- Izi zimaphatikizapo kugwiritsa ntchito mafunde a ultrasound kutsegula kwakanthawi chotchinga cha magazi ndi ubongo , chomwe chimaletsa mankhwala oletsa khansa kulowa mu ubongo.
- Izi zikadali mu gawo lofufuza , ndipo zitenga nthawi kuti zigwiritsidwe ntchito mwa anthu.
- Izi zitha kugwiritsidwa ntchito mtsogolo ngati chowonjezera kapena njira ina m'njira zina monga opaleshoni ya ubongo, chemotherapy, ndi chithandizo cha radiation.
- Ngati inu kapena munthu amene mumamudziwa ali ndi nkhawa iliyonse yokhudza matenda a khansa, nthawi zonse kambiranani ndi dokotala wanu.
