Mob Drinkers Nrhiav Kev Zoo Tshaj Tawm Ntxiv
Cov neeg haus dej qab zib muaj peev xwm tuaj yeem tshwm sim, tiam sis yog tias lawv mob los yog raug mob, lawv yuav kho tsis yooj yim. Kev haus cawv muaj kev nyuaj siab nyob rau hauv lub cev thiab qhov hloov ntawm lub cev tsis muaj zog.
Lub koom haum Salk txoj kev tshawb nrhiav cov tsiaj kuaj pom tias kev haus dej caw ntev mus ntev tuaj yeem ua rau lub cev muaj peev xwm los teb tau cov kev ntxhov siab xws li kev mob lossis kev raug mob.
Cawv ntau dhau lawm yuav ua rau koj mob tau los ntawm kev txo zog ntawm koj lub cev qhov kev tiv thaiv, cov kws tshawb fawb tau thov.
Catherine Rivier, xibfwb nyob rau hauv Clayton Foundation Laboratories rau Peptide Biology nyob rau hauv lub koom haum Salk hauv La Jolla, Calif., Kuaj xyuas cov teebmeem ntawm dej cawv ntawm qhov kev ntxhov siab nyob rau hauv cov lus kuaj nas. Ib pawg nas yog raug dej cawv vapors, hos lwm qhov, cov pejxeem ntawm cov nas ua haujlwm tau pab pawg tswj hwm.
Kev sib ntaus lossis kev sib tsoo davhlau
Cov nas tsuag raug haus cawv vapors rau 6 teev ib hnub rau yim hnub. Tag nrho cov nas tsuag ces raug rau ob hom kev ntxhov siab - ib qho hluav taws xob poob siab thiab txhaj tshuaj ntawm lub cev thiab lawv cov qib hormonal tau pom.
Qhov kev ntxhov siab, uas yog hu ua "sib ntaus sib tua-lossis-davhlau", yog pib hauv thaj tsam ntawm lub paj hlwb hu ua hypothalamus, uas yog zaum tob hauv nruab nrab ntawm lub hlwb.
Thaum lub cev tshwm sim rau tus kws kho mob, hypothalamus tawm cov tshuaj hormones hu ua corticotropin-release factor (CRF) thiab vasopressin (VP).
Cov kev kuaj ob leeg no mus rau ntawm lub caj pas pituitary, ua rau lub qoob loo ntawm adrenocorticotropin (ACTH), Rivier qhia.
ACTH mam li nkag mus rau hauv cov hlab ntsha thiab ua rau qog lub qog ua kom qis corticosteroids. Cov tshuaj no ua rau kev hloov cev ntawm cov as-ham, xws li cov suab thaj, rau lub cheeb tsam ntawm lub cev uas muaj kev ntxhov siab.
Kev nyuaj siab tuaj yeem nqa ntawm kev mob
Hauv cov nas tsuag dej, cov tshuaj hormone qib tseem nyob li qub thiab raws li kev xav tau. Hauv cov cawv pawg, theem CRF thiab VP thiab cov lus teb hauv xov tooj cua hauv cov hypothalamus tau zoo heev.
Yog tias CRF qib qis dua, lub cev lus teb yuav tsis tsim nyog txaus thaum lub caij ntxhov siab, Rivier hais. "CRF yog qhov tseem ceeb rau peb qhov kev ntxhov siab."
"Kev nyuaj siab tuaj yeem ua rau kev mob kev nkeeg los ntawm kev hloov lub cev tsis muaj zog, zoo li thaum cov tub ntxhais kawm tau mob thaum lub caij kuaj lossis thaum muaj neeg tuag hauv tsev neeg," said Dipak Sarkar, tus xib fwb, thiab tus thawj coj ntawm lub koom haum ntawm cov tsiaj kev tshawb fawb ntawm Rutgers.
Qhov Tshwm sim ntawm Haus Dej Cawv
Rivier hais tias nws xav ua lwm yam kev tshawb fawb ntawm cawv-preferring nas, nas uas haus dej haus cawv yeem. Cov kev tshawb fawb yav tas los tau pom qhov sib txawv hauv plaw cov nas uas haus tshuaj cawv yeem thiab cov neeg, xws li cov nas nyob hauv txoj kev tshawb no, tau muab cawv tsis xaiv.
"Feem ntau ntawm peb thiab lwm tus neeg tau pom txog cov cawv cwj pwm tau raug pom ntawm tib neeg tib yam nkaus," nws hais.
