ASLO mayeso: dziwani kuti ndi za chiyani

Zamkati

• Ndi chiyani
• Zatheka bwanji

Mayeso a ASLO, omwe amatchedwanso ASO, AEO kapena anti-streptolysin O, amayesetsa kuzindikira kupezeka kwa poizoni wotulutsidwa ndi bakiteriya Streptococcus pyogenes, streptolysin O. Ngati kachilombo ka bakiteriya kameneka sikudziwika ndi kuchiritsidwa ndi maantibayotiki, munthuyo amatha kukhala ndi zovuta zina, monga glomerulonephritis ndi rheumatic fever, mwachitsanzo.

Chizindikiro chachikulu chodwala ndi bakiteriya iyi ndi zilonda zapakhosi zomwe zimachitika koposa katatu pachaka ndipo zimatenga nthawi kuti zithetse. Kuphatikiza apo, ngati pali zizindikiro zina monga kupuma movutikira, kupweteka pachifuwa kapena kupweteka pamfundo ndi kutupa, ndikofunikira kukalandira chithandizo chamankhwala, chifukwa mwina ndi matenda a rheumatic fever. Dziwani chomwe chiri rheumatism m'magazi.

Kuyesaku kuyenera kuchitika m'mimba yopanda kanthu kwa maola 4 mpaka 8, kutengera malingaliro a dokotala kapena labotale, ndipo zotsatira zake zimatulutsidwa pambuyo pa maola 24.

Ndi chiyani

Dokotala nthawi zambiri amalamula mayeso a ASLO pomwe munthuyo amakhala ndi zilonda zapakhosi pafupipafupi kuphatikiza pazizindikiro zomwe zingawonetse kutentha thupi, monga:

• Malungo;
• Chifuwa;
• Kupuma pang'ono;
• Ululu wophatikizana ndi kutupa;
• Kukhalapo kwa ma nodule pansi pa khungu;
• Kukhalapo kwa mawanga ofiira pakhungu;
• Kupweteka pachifuwa.

Chifukwa chake, kutengera kusanthula kwa zizindikilo komanso zotsatira za mayeso, adotolo azitha kutsimikizira matenda a rheumatic fever, mwachitsanzo, omwe amadziwika ndi anti-streptolysin O m'magazi ambiri. Mvetsetsani momwe mungadziwire ndi kuchizira rheumatic fever.

Streptolysin O ndi poizoni wopangidwa ndi bakiteriya wonga streptococcus, the Streptococcus pyogenes, yomwe, ngati sichidziwika kapena kuthandizidwa ndi maantibayotiki, imatha kuyambitsa rheumatic fever, glomerulonephritis, scarlet fever ndi tonsillitis, mwachitsanzo. Chifukwa chake, njira zazikulu zopezera matendawa ndi bakiteriya iyi ndikuzindikira poizoniyu kudzera pakupeza ma antibodies omwe amapangidwa ndi thupi motsutsana ndi bakiteriya, yemwe ndi anti-streptolysin O.

Ngakhale zotsatira zabwino ndizodziwika ndi matenda mwa Streptococcus pyogenes, si anthu onse omwe amakhala ndi matenda a rheumatic fever, glomerulonephritis kapena tonsillitis, mwachitsanzo, komabe amayenera kuyang'aniridwa ndi adotolo, kuyesa magazi nthawi ndi nthawi komanso kuwunika mtima. Onani mayesero omwe akufunsidwa kuti muwone mtima.

Zatheka bwanji

Kuyezetsa kwa ASLO kuyenera kuchitika m'mimba yopanda kanthu kwa maola 4 mpaka 8, malinga ndi malingaliro azachipatala kapena labotale ndipo amachitika potenga magazi omwe amatumizidwa ku labotale kuti akawunike. Mu labotale, amayesedwa kuti azindikire kupezeka kwa anti-streptolysin O m'magazi, zomwe zimachitika powonjezera 20µL ya reagent, yotchedwa Latex ASO, mpaka 20µL yazitsanzo za wodwalayo papepala lakuda. Kenako, homogenization imachitika kwa mphindi ziwiri ndipo tinthu timayang'aniridwa kuti tiwonjezere mbale.

Zotsatirazi akuti sizabwino ngati kuchuluka kwa anti-streptolysin O kuli kofanana kapena kosakwana 200 IU / mL, koma zotsatirazi zimatha kusiyanasiyana malinga ndi labotale momwe mayeso adayesedwera komanso zaka za munthu. Ngati kuphatikiza kumapezeka, zotsatira zake zimakhala zabwino, ndipo ndikofunikira kupanga ma dilution motsatizana kuti muwone kuchuluka kwa anti-streptolysin O m'magazi. Poterepa, adotolo atha kufunsa kuyesa kwatsopano pakatha masiku 10 mpaka 15 kuti awone ngati kuchuluka kwa anti-streptolysin kumachepa m'magazi, kumakhala kosalekeza kapena kukuwonjezeka, motero kuti awone ngati matendawa akugwira kapena ayi.

Kuphatikiza pa mayeso a ASLO, adokotala atha kufunsa zikhalidwe zakuthambo zapakhosi, chifukwa ndi komwe mabakiteriya amapezeka, kuti azindikire kupezeka kwa mabakiteriya Streptococcus pyogenes.
