Degeneration - lub degeneration ntawm no ... - piv txwv

Nyob rau hauv tib neeg, muaj ib tug txheej ntawm dab uas tshwm sim nyob rau hauv cov cellular theem. Maj mam, lawv yuav ua rau kom lub ntiaj teb no hloov nyob rau hauv cov ntaub so ntswg thiab ua pom mus rau tus liab qab qhov muag. Nyob rau txoj ntsiab cai no tshwm sim xws li daim tawv nqaij laus thiab kabmob, qhov txhab zoo, epithelial kev puas tsuaj, thiab hais txog. D. Ib tug xws li tus txheej txheem yog degeneration. Nws manifests nws tus kheej nyob rau hauv tag nrho cov uas muaj sia nyob, nrog rau lwm yam kev hloov. Degeneration - ib tug txheej txheem ntawm gradual kev puas tsuaj los yog degeneration ntawm cov ntaub so ntswg qub, uas ua rau yus mus rau lawv haumxeeb puas los yog txoj kev tuag. Zoo ib yam li cov kev hloov tshwm sim nyob rau hauv tag nrho cov kabmob thoob plaws ib tug tib neeg lub neej. Cov lom tswv yim raws li "aromorphosis", "idioadaptation", "degeneration" lub npe hu rau science txij ancient sij hawm. Lawv yog cov zoo ntawm synonymous, tab sis txhua tus ntawm cov txheej txheem tsim nyog rau lub neej ntawm tus kab mob.

Physiological degeneration - dab tsi yog qhov no?

Nyob rau hauv ib txwm tej yam kev mob, vim degeneration, hloov lub qub txheej yog ua rau ib tug tshiab epithelium (txheej tawv nqaij txheej). Nws muaj txhawb rau Atrophy hauv nruab nrog cev thiab tshuab, uas tau nyob rau hauv embryonic txoj kev loj hlob thiab twb ua tiav raws li nws txoj kev ua thaum lub sij hawm ntawm yug. Degeneration yuav tsum tau thaum lub sij hawm txoj kev loj hlob ntawm tus me nyuam, yog li nws muaj nqi loj rau tag nrho cov lub cev. Piv txwv li, thaum tus tib neeg cev pob txha ossification tsim nyog degeneration (kev puas tsuaj) ntawm cov pob txha mos. Lub epidermis muaj ob peb qhov chaw, lub sab saum toj - qhov stratum corneum. Thaum lub sij hawm nws lub neej, nws yog raug physiological degeneration ntau lub sij hawm, uas ua nyob rau hauv daim tawv nqaij yog tas li tshiab. Lwm cov piv txwv yog lub hnyav Atrophy tshwm sim nyob rau hauv lub mammary caj pas thaum lactation yuav tsum tu tsis tseg.

Pathological txheej txheem - nws yog zoo li cas? los

Tus txheej txheem yog cov ntaub so ntswg kev puas tsuaj ua mechanism ntawm ntau cov kab mob. Pathological degeneration - ib tug kev hloov nyob rau hauv ib txwm ntaub so ntswg lwm yam, extrinsic no lub cev. Xws li ib tug txheej txheem yuav tsum tau lub txiaj ntsim ntawm kev ntshawv siab ntawm lipid, protein thiab carbohydrate metabolism. Muab los ntawm ib co lwm yam cellular ntsiab yuav tshwm sim nyob rau hauv tej khoom hauv nrog cev los yog cov ntaub so ntswg. Piv txwv li, adipose degeneration. Feem ntau txoj kev no yuav siv sij hawm qhov chaw nyob rau hauv lub subcutaneous cov ntaub so ntswg thiab ob lub mis mob cancer, tab sis tus kab mob no tshwm sim nyob rau hauv lwm yam ntaub so ntswg, xws li lub paj hlwb. Raws li ib tug tshwm sim, ib tug txo nyob rau hauv lub zog hauv nruab nrog cev kom txog rau thaum lawv tiav qhaj ntawv. Sib hloov nyob rau hauv lub paj fibers ntawm lub pulses tsum mus cuag lub paj hlwb, thiab vice versa, rov qab mus rau cov ntaub so ntswg. Qhov no yuav ua rau ib tug tsis rhiab heev, hloov kev ntshawv siab, atrophic dab. Tshaj carbohydrates kuj yog ib tug txim ntawm lub degeneration. Yog li muaj ib qho kab mob - mob ntshav qab zib, uas muaj ib tug ntau ntawm teeb meem.

Yuav ua li cas yog qhov txawv cystic degeneration?

Qhov no hom ntawm tus kab hloov nyob rau hauv lub teeb implies lub rov tshwm sim ntawm cov hlwv kab noj hniav uas muaj cov kua txheem. Tej zaum lawv yuav tshwm sim nyob rau hauv ib tug ntau yam ntawm ntaub so ntswg, tab sis yog feem ntau tsim nyob rau hauv tus poj niam qhov chaw mos kabmob - zes qe menyuam. Tus kab mob yuav siv sij hawm nws lub npe, raws li cov Stein-Leventhal syndrome. Tsaug rau cov ob zaum (Stein thiab Leventhal) cystic degeneration ntawm zes qe menyuam muaj tau qhib. Cov ua ntawm no syndrome tseem tsis paub hais tias mus tam sim no lub sij hawm, li cas los xij, muaj ib tug assumption tias tus kab mob yog raws roj ntsha. Nws zoo nkaus li thaum lub sij hawm tiav nkauj tiav nraug poj niam, lub ntsiab tsos mob yog qhov uas tsis ua poj niam. Lub mechanism ntawm tus kab mob yog lub tsim ntawm ntau yam ntawm zes qe menyuam hlwv, uas muaj nruj capsule thiab pab txhawb kom muaj kev cuam tshuam ntawm kev loj hlob thiab maturation ntawm cov hauv paus, yog li ua txhaum lub qe tso zis txheej txheem.

Cov soj ntsuam daim duab thiab kev kho mob ntawm cov syndrome Stein-Leventhal

Sib nrug los ntawm cov tsis muaj menses nyob rau hauv cov tub ntxhais hluas, degeneration - ib tug kab mob uas tshwm sim nyob rau hauv lwm yam mob ntawm lub voj voog. Piv txwv li, metrorrhagia - periodic los ntshav los ntawm qhov chaw mos huam uas tsis cob cog rua nrog ovulatory hloov nyob rau hauv tus poj niam lub cev. Yog hais tias Stein-Leventhal syndrome nyob tom qab nyob rau hauv lub neej, ces nws cov ntsiab manifestation yog ntxiv lawm tshob. Nyob rau hauv cov ntaub ntawv no, tej zaum nws yuav tshwm sim nyob rau hauv yav tas los cev xeeb tub cov poj niam thiab cov poj niam muab yug. Nyob rau hauv tas li ntawd, tus kab mob no yog manifested los ntawm ib tug qhia tau hypertrichosis - kom plaub hau kev loj hlob nyob rau hauv lub ntsej muag thiab lub cev ntawm cov neeg mob. Nyob rau hauv tas li ntawd, cov tsos mob, tej yam tshwm sim ntawm virilization yog tsis muaj, cov poj niam muaj qub kev sib deev yam ntxwv, lub suab, hom Constitution. Nervousness ntawm Stein-Leventhal syndrome txuam nrog impaired fertility zog. Kev kho mob ntawm tus kab mob yog ntawm zes qe menyuam npoo resection los ntawm cov uas lub hauv paus pib paub tab thiab tsim qe hlwb, li no es fertility.

Sib hloov nyob rau hauv lub qhov muag

Vim lub cev ntawm nyob quavntsej muaj lub peev xwm mus saib lub ntiaj teb no. Thaum pathological kev hloov, qhov no muaj nuj nqi yog tsis hnov txawm dig muag. Qhov muag mob tej zaum yuav laus nyob rau hauv nws cov ntau lug: cornea, iris, vitreous lom zem, lens, cov hlab ntsha, thiab lwm yam Cov feem ntau loj heev pathologies pom tau hais tias kev hloov nyob rau hauv lub retina thiab optic paj ... Txij li thaum cov lug yog txuam nrog rau lub hlwb, lawv tau dig ua rau irreversible dig muag. Ntsiab degeneration - ib tug kab mob ntawm tsis paub hais tias etiology. Nws manifests nws tus kheej nyob rau hauv daim ntawv ntawm cov muaj hnub nyoog txog degeneration los yog retinitis, uas muaj peev xwm tshwm sim thaum twg los tau lub sij hawm ntawm lub neej. Degeneration - Piv txwv: amelanotic thiab pigmentary daim ntawv no, unilateral, paravenoznaya, central thiab peripheral pathology.

Lub pathogenesis ntawm pigmentary retinal degeneration

Cov ua ntawm tus kab qhov muag hloov nyob twj ywm tsis paub hais tias, tab sis nws yog ntseeg hais tias lawv yog roj ntsha thiab yuav kis tau raws li ib tug tseem ceeb thiab ib tug recessive noob. Qhov loj pathological mechanism ntawm tus kab mob yog lub degeneration ntawm cov rods thiab cones, nyob rau lub retina. Vascular mob ob lub qhov muag yog nyob rau hauv txoj kev loj hlob adventitia thiab thooj ntawm lub endothelium. Paj fibers ntawm hloov khoom nruab nrog kuj yuav proliferate thiab maj displace retinal txheej, nyob rau lub thawj rods yog moog, thiab nyob rau hauv advanced txheej txheem - cones. Nyob rau hauv unevenly faib xim degeneration ntawm ib lub qhov muag hauv qab, raws li ib tug tshwm sim ntawm nws tsis muaj ib co feem, thiab lwm yam - opposite.

Manifestation pigmentary degeneration

Ntsiab degeneration ntawm lub qhov muag yog qhia maj. Feem ntau cov feem ntau, nws pom nyob rau hauv thaum yau los yog thaum tiav hluas. Tus thawj cov tsos mob ntawm tus kab mob no yog ib hnub twg-dig muag - kev nyuaj nyob rau hauv dim lub teeb. Qhov no tej zaum yuav tsuas manifestation rau ob peb lub xyoo, nrog kev hloov nyob rau hauv ophthalmoscopy yuav tsis muaj cai. Cov theem tom ntej ntawm tus kab mob no yog cov tsos ntawm me me qhov chaw ntawm xim nyob rau hauv txoj kev tshawb no ntawm lub ocular fundus. Cov no muaj xws, ua ntej, pom tsuas yog nyob rau hauv lub periphery, tom qab lawv mus rau qhov chaw ntawm lub retina. fundus hlab ntsha maj roj, lawv ua pom nyob rau hauv cov cheeb tsam ntawm depigmentation. Lwm cov tsos mob yog lig scotoma nyob rau hauv daim ntawv ntawm ib tug nplhaib - ib tug semicircular narrowing lub teb pom. Cov theem kawg ntawm degeneration yog nws teeb meem, uas muaj xws li theem nrab cataract, glaucoma thiab vitreous opacities. Tag nrho cov dab ua rau ib tug txo nyob rau hauv lub zeem muag thiab tej zaum kuj ua kom tiav dig muag.

degeneration mob

Neeg phem degeneration yuav ua tau nyob rau hauv txo cov kev ua ntawm cov kabmob, uas tshwm sim maj. Thaum hloov nyob rau hauv polycystic zes qe menyuam thiab muaj cov yam ntxwv soj ntsuam daim duab no yog tsim nyog los resect lub cev tom histological thiab cytological kev tshawb fawb, uas yuav tsum tau pom kev hloov tshwm sim nyob rau hauv cov cellular theem. Degeneration ntawm cov retina yuav paub meej tias rau tej yam kev tsis txaus siab ntawm tus neeg mob thiab ophthalmoscopy. Txoj kev tshawb fawb pub rau peb saib lub fundus xim inclusions hloov cov hlab ntsha, optic paj Atrophy. Lwm txoj kev yog tus electroretinogram. Nws yuav pom nyob rau lub degeneration ntawm cov weakening ntawm lub vuag los yog lawv tsis tiav disappearance.

Tshuaj kho mob ntawm retinal degeneration

Kev kho mob ntawm tus kab mob no yog aimed ntawm siv ceev xwmphem los yog npleem qhov muaj mob ntawm tus kab hloov. Qhov no yuav ua tau tiav thaum uas tau txais vasodilators "komplamin", "Nigeksina" nicotinic acid. Nyob rau hauv tas li ntawd, cov siv electrophoresis nrog antispasmodics: Drotaverinum, papaverine. Siv vitamins ntawm pab pawg neeg B. Tsis tas li ntawd medicaments xyaum phais kho mob - hloov ntawm nqaij fibers mus rau lub retina los txhim kho cov ntshav ncig. Dua li ntawm qhov kev vam meej ntawm tus kab mob, thaum ua raws li muaj peev xwm ho cuag nws.
