Dumbu: histology, budiriro uye mamiriro

Dumbu chokuita mikuru nhengo yacho zvomudumbu turakiti. Zvinoitika zvose kubudiswa zvokudya isu kudya. Izvi zvinoitwa kuburikidza hydrochloric asidhi izvo zvinowanikwa mudumbu. Izvi kwemakemikari remubatanidzwa asunungurwa nemasero kushandiswa. Sechivako mudumbu chinomiririrwa akawanda siyana tishu. Uyezve, masero secreting hydrochloric asidhi nezvimwe pakugadzira basa zvinhu zvisina achitenderera muviri. Naizvozvo anatomically dumbu ine madhipatimendi anoverengeka. Mumwe nemumwe wavo yakasiyana mune dzichipfekeka ukoshi.

Dumbu: histology of nhengo

Dumbu - negomba muviri pahombodo fomu. Kuwedzera kwemakemikari kurapwa chyme nayo zvinodiwa chekuchengeta chikafu. Kuti tinzwisise sei kugaya, unofanira kuziva histology mudumbu. sainzi ichi inodzidza nemamiriro mitumbi panguva tishu pamwero. Sezvo chikazozikamwa, mhenyu nyaya rine muzvizhinji nemasero. Ivowo, kuumba jira. Masero dzinosiyana muviri wavo chivako. Saka, chinokosha ndiyewo kwete chete. Mumwe nomumwe wavo anoita chaizvo basa. Zvomukati akaumbwa pakubhadhara anoverengeka munyama. Izvi zvinoita kuti basa ravo.

No Kusara uye mudumbu. Histology Zvidzidzo 4 akaturikidzana muviri. Wokutanga ndiwo mucous membrane. It iri romukati pechiso mudumbu. Uyezve pane submucosal rukoko. Rine adipose rinenge rine midziyo ropa uye lymphatics, uye utano hwake. Rinotevera rukoko - a tsandanyama jasi. Nemhaka yake dumbu anogona kubata uye kuzorora. Yokupedzisira ndiyo serosa. Ari neVadzidzi abdominal mhango. Mumwe nemumwe akaturikidzana izvi rinoumbwa masero, iyo pamwe chete kuumba munhu jira.

The histology of gastric mucosa

Normal histology of gastric mucosa zvinoratidza epithelial, glandular uye lymphoid tishu. Uyezve, muna Kuronga goko ane lamina muscularis zvinosanganisira wakatsetseka tsandanyama. A chepfungwa mucous rukoko mudumbu ndechokuti pamusoro pechiso pane Makomba zhinji. Vari chiri pakati omumuviri secreting dzakasiyana-siyana zvipenyu zvinhu. Next, paiva epithelial tishu. Uchiteverwa gastric mumasero. Panguva lymphoid zvinyama vanoumba lamina propria kuti ndiyo chikamu mucosa.

The glandular zvinyama ane imwe marongerwo. Iye chinomiririrwa akawanda masangano. Pakati pavo:

• Simple shwanu. Vane tubular yakarongeka.
• Mapazi shwanu.

Secretory dhipatimendi ine vakawanda exo-uye kwemakemikari anobudiswa masero. Excretory mutsinga dzinofamba nemukaka mucosal mumasero haazotaurwizve pasi pegomba riri pechiso jira. Uyezve, masero ari dhipatimendi ichi, zvakare, vanokwanisa secrete madzihwa. Pakakoromorwa pakati omumuviri vakazadzwa fibrous connective fibrous tishu.

Mune lamina propria pamusoro lymphoid zvinhu vangave mucosa. Ivo dziri diffusely, asi pepasi. Izvi zvinoteverwa tsandanyama ndiro. sezvamunoita Its inosanganisira 2 paiva dzeraundi fibers, uye 1 - longitudinal. It anopindura ane zvenguva chinzvimbo.

Histological nemamiriro mudumbu epithelium

Mucosal topsheet iyo vokukurukura zvokudya gobvu ndiro gastric epithelium. Histology pakati GI kwakatosiyana nemamiriro zvinyama iri dumbu. Epithelium kwete chete inodzivirira pemvura muviri kubva zvakakanganisika, asi anewo secretory basa. zvinyama ichi lining mukati mudumbu mhango. Riri mhiri mucosal pamusoro. No Kusara uye gastric Makomba.

The pemvura chomukati zvinenge zvakazara rimwe rukoko ane prismatic muviri glandular epithelium. Mumasero zvinyama - secretory. Dzinonzi exocrine masero. Pamwechete masero excretory ducts ari mumasero inobereka zvakavanzika.

Histology fundus mudumbu

Histology of madhipatimendi akasiyana haisi chete dumbu. Anatomically muviri rakakamurwa akawanda nhengo. Pakati pavo:

• Cardiac Department. Panguva iyi, yegurokuro anopinda mudumbu.
• Bottom. Mune imwe nzira, chikamu ichi anonzi fundic dhipatimendi.
• The muviri chinomiririrwa makuru uye duku curvature mudumbu.
• Antrum. Chikamu ichi riri vasati vapinda dumbu mukati duodenum.
• Pylorus (pylorus). Muchikamu ichi pane sphincter unobatanidza dumbu kuti duodenum. Murindi inoremekedzwa ane zvenguva nzvimbo pakati miviri iyi.

Great vasiri kukosha fundic dumbu. Histology of unyanzvi zvakaoma. The dhipatimendi ine mumasero ayo fundal pachake mudumbu. nhamba yavo vanenge mamiriyoni 35. Kudzika Makomba pakati fundic mumasero 25% mucosa. The chikuru basa dhipatimendi ichi - ndiko kugadzirwa hydrochloric acid. Pasi pokudzora kwomudzimu fuma iri kusashanda pakugadzira vanoshingaira zvinhu (pepsin) kugaya zvokudya, uyewo kudzivirira muviri akatakurirwa kwemabhakitiriya uye nemavhairasi inoramba. (Fundic) masero zvakakodzera shwanu ine mhando mbiri - exo- uye kwemakemikari anobudiswa masero.

Histology kuti submucosal gastric membranes

Miviri zvose pasi mucous Kamudzira mudumbu iri paiva mafuta tishu. Rine mukobvu vascular (venous uye arterial) plexus. Ivo kupa ropa kuti yomukati akaturikidzana mudumbu rusvingo. Kunyanya, submucosa uye tsandanyama. Uyezve, rukoko urwu ane richikurukura nhengo dzinobudisa midziyo uye tsinga plexus. The tsandanyama nguo mudumbu chinomiririrwa matatu akaturikidzana kuti tsandanyama. Zviri pachena kuchiitwa muviri ichi. Kunze uye mukati, longitudinal tsandanyama fibers. Vane mberi negwara. Pakati pavo nhema paiva dzeraundi tsandanyama fibers. Sezvaiitwa submucosa, pano pane plexus uye richikurukura nhengo dzinobudisa midziyo. Kunze dumbu serous Coated rukoko. Ndiyo visceral peritoneum.

Benign mapundu mudumbu uye ura: histology hemangioma

Rimwe benign anomera ndiyo hemangioma. Histology mudumbu uye ura paurwere ichi kunodiwa. Pashure pezvose, pasinei nokuti dzidzo chinhu benign, zvinofanira kusiyaniswa kenza. Histologically, hemangiomas vakapa vascular tishu. The masero bundu ichi kusiyaniswa zvakazara. Havazivi kwakasiyana zvakamisa hurongwa hunoumba arteries uye mutsinga muviri. Kazhinji, mudumbu hemangioma achiumbwa munyika submucosal rukoko. Typical nzvimbo iyi benign neoplasms vaiona pyloric dhipatimendi. Bundu angava inosiyana.

Kuwedzera dumbu, hemangiomas zvinogona vemunyika iri zviduku ura. idzodzo aya kazhinji anozviratidza. Zvisinei, chirwere kuti hemangiomas kunokosha. At makuru hukuru, uye kugara kunotevera (chyme, chetsoka) kunogona kuitika zvakakomba matambudziko. The chikuru kwavo kunonyengedza gastrointestinal kubuda ropa. Benign neoplasm zvakaoma kufungidzira, sezvo kazhinji kacho hapana kuratidzwa zvekuchipatara. Kana endoscopic ongororo inoratidza rakasviba rinokwanisa kucheneruka dzvuku kana dzeraundi gwapa parinobuda pamusoro mucosa. Panyaya iyi, chirwere chinonzi "hemangioma". Histology mudumbu uye ura panguva imwe chete vachishoropodza. Mune zvisingawanzoitiki zviitiko, hemangioma kaviri rakaipa kushanduka.

Patsva mudumbu; asi histology kurapa nemaronda

Mumwe zvairatidza kuti histologic kuzviongorora ndiye gastric urikanwi. zvokurwara ichi rinoitwa endoscopy (FEGDS) pamwe biopsies. Histology inodiwa vanofungidzirwa malignancy maronda. Zvichienderana padariro zvinyama kunogona kuwanikwa zvirwere zvakasiyana-siyana. Kana urikanwi kuporeswa vanga nezvokumwe mudumbu. Histology hazvisi zvakakodzera chete pamberi zviratidzo, naro inogona vanofungidzirwa akaipa tishu degeneration. Kana pasina malignancy, ari kuongorora kunoratidza sero fibrous connective tishu. Kana malignancy pamusoro gastric urikanwi histologic mufananidzo angava akasiyana. It kunoratidzwa nokuchinja mune cellular Kuronga zvinyama, kuvapo masero undifferentiated.

Nokuti chinangwa akaita histology mudumbu?

Mumwe zvomudumbu turakiti, izvo kazhinji kuva namamota, mumwe mudumbu. Histology yaifanira pasi chero kuchinja kubva mucosa. The zvairatidza chidzidzo ichi ndivo zvirwere zvinotevera:

• Atrophic gastritis. zvokurwara ichi kunoratidzwa kuparadzwa pamusoro cellular Kuronga mucosa, anogumbura mananara, zvinoderedza pakati gastric asidhi secretion.
• Rare siyana gastritis. Izvi zvinosanganisira lymphocytic, eosinophilic uye granulomatous kuzvimba.
• Chirwere gastric uye duodenal chirwere.
• Kukura "zviratidzo duku" kuti Savitsky. Izvi zvinosanganisira vakawanda simba, kurasikirwa kudya uye kuita, uremu, abdominal kusagadzikana.
• Kuziva miedzo gastric polyps nezvimwe benign anomera.
• A zvachinja muna kunotoda uri pamwe-refu huripo peptic urikanwi. Izvi zvinosanganisira kuderedza kusimba marwadzo, mukupandukira kukura nyama zvokudya.

pathologies ava precancerous zvirwere. Izvi hazvirevi kuti murwere ane akaipa nebundu wayo localization - mudumbu. Histology kunobatsira kuona kuchinja chii kuitika mune nyama dzomuviri. Kudzivirira kukura akaipa kusanduka, zvakakodzera basa kudzidza nekukurumidza uye uzviite.

Migumisiro histology mudumbu

Histological zvakabudiswa angava akasiyana. Kana muviri rinenge isina kushandurwa, kuti microscopy akaratidza romuzvarirwo chete-rukoko prismatic glandular epithelium. Kana kutora biopsy pamusoro zvakadzika akaturikidzana zvinogona kuonekwa wakatsetseka tsandanyama fibers, adipocytes. Kana murwere ane vanga kubva mazhinji maronda, mumwe unowana dzemakwiringwindi fibrous connective tishu. Kana benign histology zvabuda zvingave zvakasiyana. Ivo vanovimba bundu (vascular, tsandanyama, nhengo dzinobudisa) akaita rakavapo kubva tishu. The chikuru chepfungwa ndiyo kukura masero benign.

Fence dumbu rinenge histology: nzira nokuda

Kuti histological kudzidza mudumbu rinenge zvakakodzera kuita biopsy ari nhengo. Kazhinji, voitakura kunze tichibatsirwa endoscopy. Midziyo yokuita FEGDS kuiswa lumen mudumbu uye dzainamatira dzinoverengeka zvidimbu muviri tishu. Biopsies vakanga chinodiwa kutora kubva wandei kure nzvimbo. Mune zvimwe zviitiko, zvinyama nokuti histological kuzviongorora chinobviswa panguva pakuvhiya. Zvadaro, matete zvidimbu ane biopsy, riri aongororwe maikorosikopu kuitwa murabhoritari.

Nguva yakareba sei histological kuongorora gastric tishu

Kana uchifungidzira nekenza zvinoda histology mudumbu. ari kuongorora nguva yakawanda sei? mubvunzo uyu chiremba chete anogona kupindura. On avhareji histology zvinotora anenge 2 weeks. Izvi zvinoshandawo yekuronga zvidzidzo Somuenzaniso, kana iwe kubvisa polyp.

Panguva oparesheni ungafanira kukurumidza histological kuongorora tishu. Panyaya iyi, kuti ongororo anotora zvishoma pane hafu yeawa.

Mune dzimwe makiriniki akaita histological ongororo?

Vamwe varwere dzinofarira apo unogona kukurumidza kuita histology mudumbu? kudzidza Izvi kuitwa makiriniki zvose kuti vane zvakafanira zvokushandisa uye murabhoritari. Urgent histology inoitwa oncology makiriniki, vamwe zvomusejari zvipatara.
