I-Ultrasoundluhlobo lwegagasi elinwebekayo lemishini ephakathi nendawo. Kuyifomu yegagasi. Ngakho-ke, ingasetshenziswa ukuthola ulwazi lwe-physiological kanye ne-pathological yomzimba womuntu, okungukuthi, i-ultrasound yokuxilonga. Ngesikhathi esifanayo, futhi kuwuhlobo lwamandla. Uma umthamo othile we-ultrasound usakazeka ezintweni eziphilayo, ngokusebenzisana kwazo, ungabangela izinguquko emsebenzini kanye nesakhiwo sezinto eziphilayo, okungukuthi, umphumela we-ultrasonic biological.

Imiphumela ye-ultrasound kumaseli ikakhulukazi ihlanganisa umphumela oshisayo, umphumela we-cavitation kanye nomphumela wemishini. Umphumela oshisayo ukuthi lapho i-ultrasound isakazeka phakathi nendawo, ukungqubuzana kuvimbela ukudlidliza kwamangqamuzana okubangelwa i-ultrasound futhi kuguqule ingxenye yamandla ibe ukushisa okuphezulu kwendawo (42-43 ℃). Ngenxa yokuthi izinga lokushisa elibucayi elibulalayo lezicubu ezivamile lingu-45.7 ℃, futhi ukuzwela kwezicubu ze-Liu ezivuvukele kuphakeme kunokwezicubu ezivamile, ukuguqulwa kwe-metabolism yamangqamuzana e-Liu avuvukele aphazamisekile kulokhu kushisa, futhi ukuhlanganiswa kwe-DNA, i-RNA namaprotheni kuyathinteka, Ngakho-ke ukubulala amangqamuzana omdlavuza ngaphandle kokuthinta izicubu ezivamile.

Umphumela we-Cavitation wukuthi ngaphansi kwe-ultrasonic irradiation, ama-vacuoles akhiwa ezintweni eziphilayo. Ngokudlidliza kwama-vacuoles nokuqhuma kwawo okunodlame, kukhiqizwa umfutho we-shear owenziwe ngomshini kanye nesiyaluyalu, okwenza ukuvuvukala kuka-Liu ophe, ukuhlakazeka kwezicubu kanye ne-necrosis.

Ngaphezu kwalokho, lapho ibhamuza le-cavitation liphuka, likhiqiza izinga lokushisa eliphakeme ngokushesha (cishe i-5000 ℃) nokucindezela okuphezulu (kufika ku-500 ℃) × 104pa), okungakhiqizwa ukuhlukaniswa okushisayo komphunga wamanzi i-OH radical ne-H athomu, nge-OH radical kanye ne-redox ye-redox ebangelwa ukusabela kwe-redox, i-redox ye-redox ingaholela ku-Hmer atomtiation reaction. i-lipid peroxidation kanye nokubulawa kwamaseli.
