Khothatso ea secretion + e holofetse ea ho tsoa
Phetolelong ea trypsinogen ho trypsin:
Ts'ebetso ea li-proenzymes (ho kenyeletsoa lipases) | Ho qosoa ke li-kinins tse tsoang kininogen | Phospholipase Ts'ebetso |
Ho phatloha ha mafura a cellular ho glycerin le bile acid | Sebopeho sa bradykinin, histamine, serotonin | Ho ntšoa ha li-lymoscithin tse nang le chefo le li-lysocephalin tse tsoang liphoofolong tsa sele |

Motheo oa pathogenesis ea pancreatitis e matla ke lits'ebetso tsa litlamorao tsa lehae le tsa tsamaiso ea li-enzymes tsa pancreatic le li-cytokines tsa tlhaho e fapaneng. Khopolo ea enzyme e nang le karolo e ka sehloohong ea trypsin ho pathogeneis ea lefu lena e nkoa e le eona e etellang pele. Ho kopana ha lintlha tse 'maloa tse bakang khatello ea kelello ka har'a polyetiology ea pancreatitis e matla ke ntlha ea mantlha ea ts'ebetso e kenang ea li-enzyme tsa protheine le ho hlohlona kahare ho manyeme. Boemong ba cytoplasm ba sele ea acinar, ho kenngoa karoloana ea li-agmogenic granules le lysosomal hydrolase (ka "khopolo ea" colocalization "), ka lebaka leo liprotheine li hlahisoang ka tokollo e latelang ea liprotheine ho" pancreatic interstitium ". Ho kenngwa tshebetsong ha trypsinogen le phetoho ea eona ho trypsin ke sesebelisoa se matla sa li-proenzymes tsohle tse ling ka ho thehoa ha papali ea karabelo e matla ea pathobiochemical. Bohlokoa bo boholo ho pathogenesis ea lefu lena ke ts'ebetso ea peleho ea lisebelisoa tsa enzyme, mme ts'ebetso ea ts'ebetso ea pele e amanang le tšenyo ea likarolo tsa lisele le ho sitisoa ha litšebelisano tsa transmembrane.
E 'ngoe ea mekhoa ea' nete ea pathogenesis ea pancreatic necrosis ha ho senyeha sele ea acinar ke phetoho ea phallo ea calcium ions ka seleng le hole, e lebisang ts'ebetsong ea trypsin. Ka keketseho e ntseng e eketseha ea calcium ions ka seleng, ho kenella ka hare ho methapo ea methapo (activator ea mantlha e kenellang).
Mekhoa e meng ea autoactivation ea enzyme system ka har'a makhopho: ho leka-lekana tsamaisong ea enzyme kapa ho haella ha li-trypsin inhibitors (alpha-1-antitrypsin kapa alpha-2-macroglobulin), ho nts'etsapele 'mele oa phetoho ea mofuta o lumellanang.
Trypsin ke ts'ebetso ea mantlha ea moferefere oa ts'ebetso e matla ea pathobiochemical, empa ho teba ha methapo ea methapo ea methapo ho bakoa ke ketso ea motsoako o kopanetsoeng oa lits'ebetso tsohle tsa pancreatic enzyme (trypsin, chymotrypsin, lipase, phospholipase A2, elastase, carboxypeptidase, collagenase, jj.).
Li-enzymes tsa "pancreatic activated" li sebetsa e le lintho tsa mantlha tsa mabifi, li na le phello ea lehae, kena sebakeng se khutlisang, mokokotlo oa mpa, ka mothapo o kenang ka har'a sebete le kahare ho methapo ea methapo ho potoloha tsamaiso ea methapo. Phospholipase A2 e senya li-membrane tsa sele, lipase hydrolyzes intracellular triglycerides ho mafura acid, tseo, ha li kopantsoe le calcium, li etsa likarolo tsa sebopeho sa mafura (lipolytic) necrosis ka har'a manyeme, fiber ea sebaka se khutlang le peritoneum. Trypsin le chymotrypsin li baka protheine ea protheine ea lisele, elastase e senya lebota la sejana le likarolo tsa methapo tse sebetsanang le methapo, e isang kholisong ea hemorrhagic (proteinolytic) necrosis. Tsepamiso e hlahang ea necrobiosis, necrosis e nang le potoloho ea phello ea phello ea ho ruruha makhophong le litonong tsa morao-rao ke aseptic.
Khokahano ea bohlokoa ho pathogenesis ea pancreatitis e matla ke ts'ebetso ea trypsin ea ts'ebetso ea kallikrein-kinin ka sebopeho sa lintlha tsa bobeli tsa mabifi: bradykinin, histamine, serotonin. Sena se tsamaisana le ho eketseha ha tumello ea methapo ea methapo, ho holofala ha microcirculation, sebopeho sa edema ka har'a manyeme le sebaka sa ho khutlisa, ho eketseha ha exudation ho ea ka mpeng ea mpa.
Lintho tsa mabifi tse laeloang karolo ea boraro tse amehang ho ts'oaetso ea ts'oaetso ea ts'oaetso ea lehae, le ts'oaetso ea methapo ea methapo, ho se sebetse hantle ha pelo le ho hema, ho kenyelletsa lisele tsa mononuclear, macrophages le neutrophils tsa bahanyetsi ba fapaneng ba ts'oaetso (cytokines): li-interleukins 1, 6 le 8, necrosis factor tumors, platelet activation factor, mofuta o sa pancreatic oa phospholipase A2, prostaglandins, thromboxane, leukotrienes, nitric oxide.
Li-cytokine tsa Proinflammatory li kenyelletsa: li-tumor necrosis factor, li-interleukins 1-beta le 6, le tse thibelang mafu - li-interleukins 1 le 10. Qalong ea lefu lena, khatello ea methapo ea methapo ea methapo mokhoeng oa mokokotlo, sebete, matšoafo, ho pharalla le tsamaiso ea mali e eketseha, e hlalosang lits'ebetso tsa nts'etsopele. tsa lehae, setho le tsamaiso ea methapo ea ts'oaetso.
Li-Enzymes, li-cytokine le metabolites ea tlhaho e fapaneng, e thehiloeng nakong ea pancreatitis e hlobaetsang manyeme, sebaka sa ho khutla, mokokotlo oa mokokotlo le leseli la phepelo ea ka mpeng, e kenella ka potlako maling le ka methapo ea thoracic lymphatic tsamaisong ea potoloho le pancreatogenic toxin. Litho tsa pele tse lebisitsoeng ha li le tseleng e tlohang sebakeng sa ho khutla li ea litho tsa tšebetso ea mpa e eketsehileng ke sebete le matšoafo, pelo, boko le liphio. Sephetho sa phello e matla ea cytotoxic ea metsoako ena ea biochemical qalong ea lefu ke nts'etsopele ea manyeme a pancreatogenic le mathata a mangata a setho a khethollang ho teba ha boemo ba mokuli ka pancreatitis e matla.
Ho pathogenesis ea mathata a systemic, le pele ho nts'etsopele ea mathata a septic, toxinemia ea baktheria 'me ka holim'a tsohle, lipopolysaccharide ea leseli la lisele tsa libaktheria tsa gram-negative (endotoxin), e hlahisitsoeng ka lumen ea pampitšana ea gastrointestinal ka microflora ea mala. A pancreatitis e hlobaetsang, motsamao oa "microslora" ea endo native le "endotoxin" ea "gram-negative" e etsahala ka tlas'a maemo a tšoanang a ts'ebetso (e fokolang morphological) ea ts'ebetso ea metabolic le thibelo ea "gastrointestinal", system ea reticuloendothelial ea sebete le matšoafo.
Ho sisinyeha ha "microflora ea" "mesifa" ho tsoa mpeng ea mpa ea ka mpeng ho kenella liseleng tsa manyeme le sebaka sa ho rarolla ke sona sehokela sa pathogenesis ea pancreatitis e senya. Ts'ebetso ena ke khokahano e hokahanyang pakeng tsa "pele" (pele ho ts'oaetso), le e latelang, "morao" (septic), methapo ea pancreatitis e mpe.
Ho pathogenesis ea pancreatitis e hlobaetsang, likarolo tse peli tse ka sehloohong li khetholloa. Karolo ea pele e hlahisoa ke ho fetoha ha methapo ea methapo ka nako ea matsatsi a pele ho tloha ho qala ha lefu lena, ha ho ruruha, ho phunyelletsa ha motho ka boeona, necrobiosis le necrosis ea manyeme, lithane tse khutlisang mahlo. Tlas'a maemo ana, bekeng ea pele ea lefu lena, ho latela botebo ba mathata a pathomorphological, ho bopa mefuta e latelang ea pancreatitis e mpe e ka etsahala:
ka necrobiosis, ho ruruha le ho tsitsipanya ha tšebetso, pancreatitis e bohloko ea "li" ("adematous form"),
ka mafura kapa hemorrhagic necrosis - e sa sebetseng ea pancreatic necrosis (necrotic pancreatitis).
Botebo ba boemo ba mokuli bo nang le pancreatitis e matla ke ka lebaka la pathomorphology ea lefu lena le pancreatogenic toxinemia, ho makala ha pancreatogenic le ho hloleha ha litho tse ngata. Ka mehato ea kalafo e tlang ka nako, ts'ebetso ea methapo e ka emisoa sethaleng sa "pancreatitis" ea methapo, athe maemong a fapaneng, e fetoha pancreatic necrosis.
Ka tsoelo-pele ea lefu lena le phello ea pancreatic necrosis, ts'ebetso ea phetoho ea methapo ea methapo ho ea karolong ea bobeli (septic) ea pancreatitis e mpe, e amanang le ts'oaetso ea libaka tsa necrosis tsa lehae tse fapaneng ka beke ea 2-3 ea lefu lena. Tlas'a maemo ana, ts'ebetso e nchafatsang le ho hlahisa bobuelli ba boemeli bo tšoanang le mohato oa pele hoa etsahala, ntho e mpang e le chefo ea likokoana-hloko tse ikopanye le libaka tsa necrosis.
