Asayansi a NRNU MEPhI aphunzira momwe angagwiritsire ntchito plasma yozizira mu biomedicine Ofufuza a NRNU MEPhI, pamodzi ndi ogwira nawo ntchito ochokera ku malo ena a sayansi, akufufuza mwayi wogwiritsa ntchito plasma yozizira kuti adziwe ndi kuchiza matenda a bakiteriya ndi mavairasi ndi machiritso a mabala. Chitukuko ichi chidzakhala maziko opangira zipangizo zamakono zamakono zamakono. Madzi a m'magazi oziziritsa kukhosi ndi kusonkhanitsa kapena kutuluka kwa tinthu ting'onoting'ono timene timatulutsa timadzi timene timagwiritsa ntchito magetsi ndipo timatentha kwambiri, mwachitsanzo, pafupi ndi chipinda. Panthawiyi, zomwe zimatchedwa electron kutentha, zomwe zimagwirizana ndi mlingo wa chisangalalo kapena ionization ya mitundu ya plasma, imatha kufika madigiri zikwi zingapo.
Zotsatira za plasma yozizira zitha kugwiritsidwa ntchito muzamankhwala - monga topical agent, ndizotetezeka kwa thupi la munthu. Ananenanso kuti ngati kuli kofunikira, madzi a m'magazi ozizira amatha kupanga makutidwe ndi okosijeni ofunikira kwambiri, monga cauterization, ndi njira zina, zimatha kuyambitsa njira zochiritsira zobwezeretsa. Ma Chemical free radicals atha kugwiritsidwa ntchito kuchitapo kanthu pakhungu ndi mabala otseguka, kudzera m'majeti a plasma opangidwa ndi machubu opangidwa ndi plasma, kapena mwanjira ina ndi mamolekyu osangalatsa achilengedwe monga mpweya. Pakadali pano, nyali ya plasma poyambilira imagwiritsa ntchito mpweya wofooka wa mpweya wokwanira -helium or argon, ndipo mphamvu yotentha yomwe imapangidwa imatha kuwongoleredwa kuchokera pagawo limodzi mpaka makumi a ma watts.
Ntchitoyi idagwiritsa ntchito plasma yotseguka ya mumlengalenga, yomwe asayansi akhala akupanga mwachangu m'zaka zaposachedwa. Mtsinje wopitilira wa gasi womwe uli ndi mphamvu ya mumlengalenga ukhoza kupangidwa ndi ionized ndikuwonetsetsa kuti wachotsedwa mtunda wofunikira, kuchokera pa mamilimita angapo mpaka masentimita khumi, kubweretsa kusalowerera ndale kwazinthu kukuya kofunikira kudera linalake (mwachitsanzo, khungu la wodwalayo).
Viktor Tymoshenko anatsindika kuti: “Timagwiritsa ntchitoheliummonga mpweya waukulu, umene umatithandiza kuchepetsa oxidation zapathengo njira. Mosiyana ndi zochitika zambiri zofanana ndi zimenezi ku Russia ndi kumaiko akunja, mu miuni ya plasma imene timagwiritsa ntchito , kubadwa kwa madzi a m’magazi a helium ozizira sikumayendera limodzi ndi kupangidwa kwa ozone, koma panthaŵi imodzimodziyo kumapereka chiyambukiro chowonekera ndi cholamulirika.” Pogwiritsa ntchito njira yatsopanoyi, asayansi akuyembekeza kuchiza makamaka matenda a bakiteriya. Malinga ndi iwo, mankhwala ozizira a plasma amathanso kuchotsa kuipitsidwa kwa ma virus ndikufulumizitsa machiritso. Tikuyembekeza kuti m'tsogolomu, mothandizidwa ndi njira zatsopano, zidzakhala zotheka kuchiza matenda otupa. “Masiku ano tikungonena za kungogwiritsa ntchito pamutu. M'tsogolomu, lusoli likhoza kupangidwa kuti lilowe mkati mwa thupi, mwachitsanzo kupyolera mu kupuma. Pakadali pano, tikuyesa mayeso a in vitro, pomwe madzi a m'magazi amadzimadzi akamalumikizana mwachindunji ndi tinthu tating'ono tamadzimadzi kapena zinthu zina zachilengedwe," adatero mtsogoleri wa gulu la asayansi.
