Izvo Zvakakwana zveGentic Component Hazvizivikanwe Asi
Kunwa doro kunoratidzika kunomhanya mune dzimwe mhuri. Pane humwe uchapupu hwezvesayenzi here kuti mazamu ako anogona kukugadzirira iwe kuva doro kana vabereki vako kana vanasekuru nababa vako vari? Kunyange zvazvo zvidzidzo zvakawanda zvakaitwa uye nyanzvi dzinobvumirana kuti kune hukama hunoberekwa, genetics haisi iyo chete uye isu hatizivi chaizvo zvakakwana zvinokonzera kudhakwa.
Inodhakwa Hereditary?
Kune humwe huri huchikura huno huchapupu hwezvesayenzi hwokuti kudhakwa kune hutano. Iyo chaiyo gene inogona kuita kuti irege kuonekwa. Saizvozvowo, zvidzidzo zvezvipfuwo zveb laboratory pamwe nehutano hwevanhu zvinoratidza kuti zvizvarwa zvinowanzoita basa guru mukusimudzira doro. Kungova kukuru kwechinhu ichocho, zvinoramba zvisingagadziriswi zvakare.
Maererano neAmerican Academy of Child & Adolescent Psychiatry, vana vezvidhakwa vanowanzoita kane vana kupfuura vamwe vana kuti vave doro. Asi, zvakatipoteredza zvinogona kuva chikonzero mune zvakawanda zvezviitiko zvakare.
Chimiro Chechibereko
Mhuri, mapatya, uye kugadziriswa kwevana vakave vakaratidza kuti kudhakwa kwechokwadi kune chimiro chemazwi. Muna 1990, Blum et al. yakarongedza sangano pakati peA1 allele yeDDD2 gene uye doro. IDDD2 geni ndiyo yaiva yekutanga gwaro rakaratidza chivimbiso chekushamwaridzana nekudhakwa (Gordis et al., 1990).
Chidzidzo muSweden chakatevera kushandiswa kwewaini mumapatya avo vakagamuchirwa sevana uye vakasunungurwa. Chiitiko chekudhakwa kwakange kuchikwirira zvishoma pakati pevanhu vainge vakabatwa nedoro chete kuburikidza nemhuri yavo yekurera. Kunyange zvakadaro, yakanga yakakwirira zvikuru pakati pemapatya avo vanababa vezvisikwa vaiva doro, pasinei nekuvapo kwekudhakwa mumhuri yavo yekurera.
Zvinyorwa zvedzidzo zvekuberekwa zvakaedza kujekesa mahedheni chaiwo anokonzerwa nekudhakwa, asi hapana akabudisa zvigumisiro zvakajeka. Mamwe mazita ejeni ave akaonekwa kuti anotamba chimwe chinhu muzviito zvinokuvadza zvinoshandiswa nekudhakwa nekudhakwa kana kuvimba. Zvimwe zvakabatana zvakananga uye vamwe vane kungofanana chete.
Zvibereko Fly Zvakafanana
Vanotsvakurudza paYunivhesiti yeCalifornia kuSan Francisco (UCSF) vari kushandisa michero yemichero kuti vawane hutachiona hunokonzera kudhakwa . Maererano nevasayendisiti, kudhakwa zvinosvibisa mhuka dzinobhururuka dzinofanana nenzira iyo vanhu vanoita kana vakadhakwa. Mukuwedzera, chipukiso chekuputika kwechiroro chinoratidzika kuti chinotungamirirwa nemamwechete molecule zvinoshandiswa sevanhu.
Hugo Bellen, a geneticist paBaylor College of Medicine muHouston, Texas, akati chidzidzo "chinoshandisa nheyo yemagadzirirwo emagetsi ekuparadzanisa zvakanyanya, uye zvichida zvisingaperi, zvinokonzera" doro muvanhu .
Geneti Inonzwisisa Doro
Mune imwe dzidzo, masayendisiti akatsaura zvikafu zviviri zvemakonzo: izvo zvisingave zvakanyanyisa kunwa doro, uye izvo zvakagadzikana zvakanyanya. Iyo miviri miviri inoratidza maitiro akasiyana zvakasiyana apo inoratidzirwa nezviyero zvakafanana zvewaini.
Iyo mhando dzakasvibirira dzinowanzosiya kukanganisa kwayo uye dzinopfuurira mberi nokukurumidza, dzichiwana mari yezita rokuti "vakarara kwenguva refu." "Kurara kwenguva pfupi" ndevecheve dzinenge dzisinganyanyi kunwa doro. Vanoita sevanorasikirwa zvishomanana nekudzivirira uye vanorega doro kwenguva refu vasati vapfuura.
Genetic Risk, Not Destiny
" Doro rinoshandiswa rinoshandiswa nekubatana kwezvakatipoteredza uye zvizvarwa," akadaro Gene Erwin, Ph.D., purofesa wemishonga yemishonga paCU School of Pharmacy, "Ichi chidzidzo chakaratidza kuti zvizvarwa zvinowanzoita zvakawanda, uye isu iri kuedza kunzwisisa simba rezvinyorwa izvi. "
Kana kudhakwa kunogona kutariswa kune rimwe geni kana kusanganiswa kwemajini, ruzivo rungashandiswa sei?
"Majena aya ndeazvipingamupinyi, kwete zvekupedzisira," akadaro Dr. Enoch Gordis, mutungamiriri weNational Institute on Alcohol Abuse and Alcoholism. Akawedzera kuti tsvakurudzo inogona kubatsira pakutsanangura vechidiki pangozi yekuva doro uye zvinogona kutungamirira pakuedza kudzivirira kare.
Izvi zvinoreva kumhuri yemadhakwa ndeyekuti hausi kureva kushandisa zvinodhaka iwe pachako. Zvisinei, matanho ako ekuvandudza hutano akakwirira kupfuura mamwe.
Zvisikwa zvinongodarika hafu ngozi yako yekudhakwa. Zvinhu zvakadai semamiriro ako ehupenyu uye kukwanisa kwako kugadzirisa mamiriro ezvinhu angaita kuti munhu azvimirire zvakakosha. Izvi ndizvo zvatinokwanisa kuramba tichiyeuka sezvo isu tichienderera mberi kukudziridza kunzwisiswa kwekudhakwa pamunhu pachake.
