“Ntho e 'ngoe le e 'ngoe e hola ka lebaka la khanya ea letsatsi”. Khanya ea letsatsi e na le mefuta e fapaneng ea khanya, eo e 'ngoe le e 'ngoe ea eona e nang le bolelele ba leqhubu bo fapaneng, bo bontšang 'mala o fapaneng. Lebaka ke hobane khanya e kenella ka botebo ka har'a lisele 'me e na le liphello tse fapaneng linthong tse phelang.
Moprofesa oa Sekolo sa Bongaka sa Harvard, Michael Hamblin, o phatlalalitse lingoloa tsa lipatlisiso tse bontšang hore leseli le lefubelu le ka hlahisa letoto la litlamorao tsa mocheso, litlamorao tsa photochemical, le likarabelo tse ling tsa baeloji. Le ka boela la kenella liseleng tsa batho ho fihlela ho 30mm kapa ho feta, ka kotloloho methapong ea mali, methapong ea lymphatic, pheletsong ea methapo le liseleng tse ka tlas'a letlalo. Lebaka ke hobane leseli le lefubelu la mofuta ona ha le fumanehe mefuteng e meng ea leseli, 'me ka hona le tsejoa e le "fensetere ea optical" ea letlalo la motho.
Leseli le lefubelu le monngoa joang ke 'mele?
Ka har'a lisele tsa 'mele ea rona, leseli le monngoa haholo ke liprotheine, mebala le limolek'hule tse ling tse kholo, hammoho le limolek'hule tsa metsi. Kaha limolek'hule tsa metsi le hemoglobin tse leboteng la leseli le lefubelu la coefficient ea ho monya leseli li nyane, li-photon li ka kenngoa ka botebo liseleng hore li be le phello e tsamaellanang ea phekolo. Leseli le lefubelu le 'mele oa motho li haufi haholo le mahlaseli a maqhubu a motlakase, 'me li boetse li tsejoa e le "leseli la bophelo"! E boetse e tsejoa e le "leseli la bophelo".
Chate ea Tlaleho ea Lipatlisiso ea 2Ho monngoa ha mebala e fapaneng ea leseli ke lisele tsa letlaloHo phaella moo, boemong ba sele, mitochondria ke tsona tse monyang khanya e khubelu ka ho fetisisa. Lehlakore la khanya e khubelu le tšoana le lehlakore la khanya ea mitochondria, 'me li-photon tse monngoang li kenngoa 'meleng oa motho, e leng se fellang ka karabelo e sebetsang hantle ea baeloji ea photochemical - karabelo ea enzymatic. Karabelo ena e ntlafatsa ts'ebetso ea mitochondrial catalase, superoxide dismutase le li-enzyme tse ling tse amanang le metabolism ea matla, e potlakisang tlhahiso ea ATP, e eketsa phepelo ea matla ea lisele tsa lisele le ho potlakisa ts'ebetso ea metabolism le ho tlosoa ha metabolism e chefo 'meleng. E potlakisa tsela eo 'mele o metabolismang le ho ntsha chefo ka eona.
Mitochondria ke di-amplifier tse kgolo ka ho fetisisa tsa lesedi le lefubedu boemong ba sele. Lehlasedi la lesedi le lefubedu le tshwana le lehlasedi la ho monya la mitochondria, mme di-photon tse monngwang di kenngwa mmeleng wa motho, e leng se fellang ka karabelo e sebetsang hantle ya photochemical baeloji - karabelo ya enzymatic. Karabelo ena e ntlafatsa mosebetsi wa mitochondrial catalase, superoxide dismutase le dienzyme tse ding tse amanang le metabolism ya matla, e potlakisang tlhahiso ya ATP, e eketsa phepelo ya matla ya disele tsa dinama mme e potlakisa tshebetso ya metabolism le ho ntsha metabolism e chefo mmeleng. E potlakisa tsela eo mmele o metabolismang le ho ntsha chefo ka yona.
Phuputso e 'ngoe e bontša hore mahlaseli a khanya e khubelu a ka fetola tlhahiso ea liphatsa tsa lefutso tse amanang le metabolism ea tsoekere, lipid le protheine, e leng se etsang hore ho be bonolo hore li-fibroblast li sebelise mafura a mangata e le thepa e tala bakeng sa ho etsa ATP, kahoo li potlakisa ts'ebetso ea mafura; 'me ka nako e ts'oanang, e ka boela ea etsa hore tlhahiso ea liphatsa tsa lefutso tse amanang le metabolism ea matla e laolehe, joalo ka NADH dehydrogenase, ATP synthetase, le liprotheine tsa flavin tse fetisang lielektrone, tse thusang ho lokisa le ho nchafatsa lisele tse senyehileng, le ho hlasimolla lisele tsa methapo ho fihlela sepheo sa kalafo. E ka boela ea hlasimolla lisele tsa methapo ho fihlela sepheo sa kalafo.

Litlamorao tsa leseli le lefubelu 'meleng oa motho
Ho na le dingolwa tse ngata le diteko tsa bongaka mabapi le kamoo lesedi le lefubedu le amang botle, ho fola le ho itshireletsa mafung. Hape le bapala karolo ya bohlokwa ho kgothalletseng ho thehwa ha corpus luteum ka hara ovary, ho laola tlhahiso ya dihormone tsa thobalano, ho ntlafatsa pono, ho theola boima ba mmele le mafura, le ho imolla maikutlo.
Leseli le lefubelu le ka ntlafatsa 'mala oa letlalo. Lithuto tse ling li bontšitse hore leseli le lefubelu le ka thibela tšebetso ea tyrosinase, e leng enzyme e thusang ho etsa 'mala oa letlalo. E ka boela ea kenya tšebetsong protheine e bitsoang extracellular regulated protein kinase, e ka fokotsang tlhahiso ea tyrosinase le liprotheine tse ling tse amanang le eona. Sena se ka thusa ho ntlafatsa 'mala oa letlalo le ho fokotsa mathata a pigmentation, joalo ka matheba, makhopho le ho fifala ha letlalo ho hong.

Leseli le lefubelu le etsa hore ho be bonolo ho tsoela pele ho ikoetlisa leha u khathetse. Bafuputsi ba fumane hore leseli le lefubelu metsotso e 20 le ka ntlafatsa maemo a oksijene maling le ho fokotsa tšebeliso ea 'mele ea tlhahiso ea matla a anaerobic, e leng se lebisang ho bokellaneng ha lactic acid e ngata nakong ea boikoetliso.
