Ucwaningo Lwezokwelapha Izidakamizwa Zezilwane
I-Pendahuluan
I-toxicology yezidakamizwa zezilwane igatsha lesayensi elifunda ngemiphumela emibi yezidakamizwa ezilwaneni. Ngokuthuthuka kwemikhakha yezempilo yezilwane nezilwane ezifuywayo, ukusetshenziswa kwezidakamizwa zezilwane kukhule kakhulu. Ngakho-ke, kubalulekile ukuqonda ubuthi, umthelela, kanye nokuphathwa kwengozi kokusetshenziswa kwezidakamizwa ezilwaneni. Kulesi sihloko, sizoxoxa ngencazelo yobuthi bezidakamizwa zezilwane, ukuhlukaniswa kwezidakamizwa, izindlela zokuhlola ubuthi, kanye nokuphathwa komthelela kanye nengozi.
Incazelo kanye nobubanzi
I-toxicology yezidakamizwa zezilwane ihlanganisa ucwaningo lwesilinganiso, ukusatshalaliswa, ukwakheka kwe-metabolism, kanye nokukhishwa kwezidakamizwa ezilwaneni, kanye nemiphumela yazo engaba yingozi. Lokhu kuhlanganisa ukuthuthukisa izindlela zokunciphisa izingozi zempilo ezilwaneni, futhi kwezinye izimo, kubantu abasebenzisana nazo eduze.
Emkhakheni wezilwane ezifuywayo, izidakamizwa zisetshenziselwa ukwandisa umkhiqizo, ukuvimbela izifo, nokuthuthukisa inhlalakahle yezilwane. Ezilwaneni ezifuywayo, izidakamizwa zisetshenziselwa ukuvimbela noma ukwelapha izifo nokuthuthukisa ikhwalithi yokuphila kwazo.
Ukuhlukaniswa Kwemithi Yezilwane
Imithi yezilwane ingahlukaniswa ngezigaba eziningana ngokusekelwe emsebenzini wayo kanye nendlela esebenza ngayo:
1. Ama-antibiotic: Asetshenziselwa ukwelapha izifo ezibangelwa amagciwane. Izibonelo zifaka phakathi i-tetracycline ne-amoxicillin.
2. Ilwa nezilokazane: Ixosha noma ibulale izilokazane zangaphakathi nezangaphandle. Isibonelo, i-ivermectin kanye ne-permethrin.
3. Ilwa nokuvuvukala: Yehlisa ukuvuvukala nobuhlungu. I-Ketoprofen iyisibonelo esisodwa.
4. Ama-hormone nama-Steroids: Asetshenziswa ukulawula ukuzala nokukhula. Izibonelo zifaka phakathi i-estrogen ne-testosterone.
5. Imijovo: Ihlinzeka ngokuzivikela okusebenzayo ezifweni ezithile. Izibonelo zifaka phakathi umuthi wokugomela i-rabies kanye nomuthi wokugomela i-parvovirus.
6. Amavithamini Nezithasiselo: Kuhlinzeka ngezakhamzimba ezengeziwe empilweni yesilwane. Izibonelo zifaka phakathi amavithamini A no-E.
Indlela Yokuhlola Ubuthi
Ekwelashweni kwezidakamizwa zezilwane, kubalulekile ukunquma imithamo ephephile kanye nemiphumela emincane yobuthi. Ezinye zezindlela ezisetshenziswayo zifaka:
1. Ukuhlolwa Okubukhali: Kusetshenziselwa ukunquma i-LD50 (Umthamo Obulalayo 50), okuyisilinganiso esibulala u-50% wezilwane ezivivinyiwe ngesikhathi esifushane.
2. Ukuhlolwa Okungalapheki Nokungalapheki: Kulinganisa imiphumela yomuthi esikhathini esiphakathi kuya kweside. Lokhu kusiza ukuqonda imiphumela eqongelelekayo kanye nokulimala okungaba khona kokusetshenziswa kwesikhathi eside.
3. Ukuhlolwa Kokuba Ne-Teratogenicity kanye Nokuba Ne-Carcinogenicity: Hlola amandla omuthi okubangela ukukhubazeka kokuzalwa noma umdlavuza.
4. Ukuhlolwa Kobuthi Bomzimba: Kuhlola umthelela wemithi ohlelweni lokuzivikela komzimba.
Imiphumela Enobuthi Yezidakamizwa Ezilwaneni
Izidakamizwa zingadala imiphumela ehlukahlukene enobuthi ezilwaneni, kuye ngohlobo lomuthi, umthamo, kanye nesikhathi sokuchayeka. Eminye imiphumela evamile enobuthi ihlanganisa:
1. Ukulimala Kwesibindi (Ubuthi Besibindi): Imithi ethile, njenge-tuberculostatics, ingabangela ukulimala kwesibindi.
2. Ukwehluleka Kwezinso (Ukungasebenzi Kahle Kwezinso): Izidakamizwa ezifana nama-aminoglycosides zingalimaza ukusebenza kwezinso.
3. Ukulimala Kwezinzwa (Ubuthi Bezinzwa): Ezinye izibulala-zinambuzane nezinsimbi ezisindayo zingabangela ukuphazamiseka kwesimiso sezinzwa.
4. Izinkinga Zokuzala: Ama-hormone kanye neminye imithi kungathinta ukuzala kanye nokusebenza kokuzala.
5. Ukulimala Kwesistimu Yegazi: Le miphumela ihlanganisa i-anemia kanye nokwehla kwenani lama-platelet ngenxa yemithi ethile efana ne-chemotherapy.
Ukuphathwa Kwengozi Yobuthi
Ukuze kuncishiswe ingozi yobuthi bezidakamizwa ezilwaneni, kungathathwa izinyathelo eziningana, okuhlanganisa:
1. Isilinganiso Esifanele: Isilinganiso semithi kumele silungiswe ngokwesisindo sesilwane, ubudala, kanye nesimo sempilo yaso. Ukunikeza isilinganiso esiphezulu kakhulu noma esiphansi kakhulu kungaba yingozi.
2. Ukuqapha Nokuhlola Okuqhubekayo: Ukuqapha njalo impilo yezilwane ngemva kokunikezwa kwemithi kubalulekile ukuthola imiphumela emibi ngokushesha okukhulu.
3. Ukusetshenziswa Kwemithi Ngendlela Efanele: Ukusetshenziswa kwemithi kumele kuhambisane nokuxilongwa okufanele kanye nemithi kadokotela wezilwane.
4. Imfundo Yabasebenzisi: Abanikazi bezilwane ezifuywayo kufanele banikezwe ulwazi olwanele mayelana nendlela yokunikeza imithi kanye nezimpawu zemiphumela emibi okufanele baziqaphele.
5. Umthetho Nokuhambisana: Ukuhambisana nemithethonqubo yokusetshenziswa kwezidakamizwa ebekwe yiziphathimandla zezempilo yezilwane kungavimbela ukusetshenziswa kabi kwezidakamizwa nokusetshenziswa ngokweqile.
Imithelela Enobuthi Emvelweni Nakubantu
Ngaphezu kokuthinta izilwane, ukusetshenziswa kwemithi yezilwane kungathinta nemvelo kanye nempilo yabantu. Izinsalela zemithi zingangena emvelweni ngokukhipha kanye nezinsalela zemithi ezingasetshenziswanga. Lokhu kungangcolisa amanzi angaphansi komhlaba kanye nezitshalo, ekugcineni kuthinte ezinye izinto eziphilayo, okuhlanganisa nabantu.
Ama-antibiotic, isibonelo, ahlotshaniswa nokumelana namagciwane. Ukusabalala kokumelana namagciwane kusuka emapulazini kuya kubantu kuyindaba yomhlaba wonke edinga ukunakwa okukhulu.
Isiphetho
Isayensi yobuthi bemithi yezilwane iwumkhakha obalulekile ekuqinisekiseni impilo nenhlalakahle yezilwane, kanye nokuvimbela imiphumela emibi emvelweni nakubantu. Ukuqonda kahle ukuhlukaniswa kwemithi, izindlela zokuhlola ubuthi, imiphumela, kanye nokuphathwa kwezingozi kubalulekile ekusetshenzisweni okuphephile nokuphumelelayo kwemithi ezilwaneni.
Ngocwaningo oluqhubekayo kanye nemithetho eqinile, singaqinisekisa ukuthi ukusetshenziswa kwemithi yezilwane kusekela impilo yezilwane ngaphandle kokubeka izingozi ezinkulu emvelweni noma empilweni yabantu. Imfundo eqhubekayo yabalimi kanye nabanikazi bezilwane nayo ibalulekile ekuvimbeleni ubuthi kanye nokuthuthukisa impilo yezilwane iyonke.
