Qhov sib txawv tseem ceeb ntawm prolactin thiab oxytocin hormone yog cov tshuaj prolactin yog cov tshuaj hormones protein ua lub luag haujlwm rau kev tsim cov mis nyuj, thaum oxytocin hormone yog cov protein ntau lub luag haujlwm rau cov kua mis ejection reflex thiab uterine contraction thaum yug menyuam.
Cov tshuaj hormones tsim los ntawm cov qog endocrine yog cov proteins lossis steroids. Tsis muaj cov tshuaj hormones muaj kev ua haujlwm enzymatic. Tab sis lawv ua hauj lwm raws li chemical messengers. Protein hormones yog cov tshuaj hormones uas nws cov molecules yog peptides lossis cov proteins. Thaum cov tshuaj hormones protein khi rau ib qho receptor ntawm lub xovtooj ntawm tes, tus xa xov thib ob tshwm hauv cytoplasm ua rau lub teeb liab hloov pauv uas ua rau cov lus teb tshwj xeeb ntawm tes. Qee qhov piv txwv ntawm cov tshuaj hormones protein yog ACTH, angiotensin, calcitonin, prolactin, oxytocin, FSH, LH, rennin, TSH, thiab vasopressin. Prolactin thiab oxytocin hormones yog ob yam tshuaj hormones.
YProlactin Hormone yog dab tsi?
Prolactin hormone yog cov tshuaj hormones protein uas tsim los ntawm lactotrophs hauv lub pituitary anterior. Nws kuj tseem zais los ntawm lub caj pas pituitary hauv kev teb rau kev noj mov, kev kho tshuaj estrogen, mating, ovulation, thiab kev laus. Prolactin ua lub luag haujlwm hauv kev ua kom tsiaj txhu (feem ntau yog poj niam) los tsim cov kua mis. Cov txheej txheem no hu ua lactation. Cov protein no tuaj yeem ua rau lactation hauv cov noog. Prolactin muaj kev cuam tshuam nyob rau hauv ntau dua 300 cov txheej txheem sib cais hauv ntau lub cev pob txha. Tsis tas li ntawd, prolactin plays lub luag haujlwm tseem ceeb hauv cov metabolism, tswj kev tiv thaiv kab mob, thiab kev loj hlob ntawm pancreatic. Cov tshuaj no tau pom thawj zaug hauv cov tsiaj tsis yog tib neeg ib puag ncig xyoo 1930 los ntawm Oscar Riddle. Lub xub ntiag ntawm prolactin hauv tib neeg tau lees paub hauv xyoo 1970 los ntawm Henry Friesen. Cov tshuaj peptide no yog encoded los ntawm PRL noob.

Ntxiv rau kev txhawb nqa cov kua mis, prolactin kuj tseem txhawb kev loj hlob ntawm oligodendrocyte precursor hlwb uas sib txawv rau hauv oligodendrocytes tom qab. Tsis tas li ntawd, lwm txoj haujlwm ntawm cov tshuaj hormone no suav nrog kev txhawb nqa pulmonary surfactant synthesis ntawm lub ntsws hauv plab thaum kawg ntawm cev xeeb tub, tiv thaiv kev tiv thaiv ntawm tus menyuam hauv plab los ntawm leej niam thaum cev xeeb tub, thiab txhawb nqa neurogenesis hauv niam thiab menyuam hauv lub hlwb. Hauv lwm cov vertebrates zoo li ntses, nws koom nrog tswj dej thiab ntsev sib npaug.
Oxytocin Hormone yog dab tsi?
Oxytocin hormone yog cov tshuaj hormones protein uas tsim los ntawm hypothalamus thiab tso tawm los ntawm posterior pituitary. Nws yog lub luag haujlwm rau cov kua mis ejection reflex thiab uterine contraction thaum yug menyuam. Oxytocin raug tso tawm rau hauv cov ntshav raws li cov tshuaj hormones hauv kev teb rau kev sib deev thiab thaum lub sijhawm ua haujlwm. Cov tshuaj hormone no kuj ua lub luag haujlwm hauv kev sib txuas nrog tus menyuam thiab cov kua mis.
Daim duab 02: Oxytocin Hormone
Oxytocin hormone muaj nyob rau hauv daim ntawv tshuaj thiab. Kev tsim cov oxytocin yog tswj los ntawm kev tawm tswv yim zoo. Nws txhais tau hais tias nws thawj zaug tso tawm nkoos ntau lawm thiab tso tawm oxytocin. Cov protein no yog encoded los ntawm OXT noob. Nws yog nano peptide. Ntxiv mus, cov tshuaj oxytocin tau pom nyob rau xyoo 1909 los ntawm Sir Henry H. Dale.
Dab tsi zoo sib xws ntawm Prolactin thiab Oxytocin Hormone?
- Prolactin thiab oxytocin cov tshuaj hormones yog ob yam tshuaj hormones protein.
- Ob leeg cov tshuaj hormones yog peptides ua los ntawm cov amino acids.
- Cov tshuaj hormones no muaj nyob rau hauv tib neeg thiab lwm yam vertebrates.
- Ob qho tshuaj hormones muaj nyob rau hauv poj niam thiab txiv neej.
Qhov txawv ntawm Prolactin thiab Oxytocin Hormone yog dab tsi?
Prolactin hormone yog cov tshuaj hormones protein ua lub luag haujlwm rau kev tsim cov mis nyuj, thaum oxytocin hormone yog cov protein ntau lub luag haujlwm rau cov kua mis ejection reflex thiab uterine contraction thaum yug menyuam. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm prolactin thiab oxytocin hormone. Tsis tas li ntawd, prolactin hormone yog encoded los ntawm PRL noob, thaum oxytocin hormone yog encoded los ntawm OXT noob.
Cov duab hauv qab no nthuav tawm qhov sib txawv ntawm cov tshuaj prolactin thiab oxytocin hauv daim ntawv qhia rau ib sab ntawm kev sib piv.
Summary – Prolactin vs Oxytocin Hormone
Prolactin thiab oxytocin cov tshuaj hormones yog ob yam tshuaj hormones protein. Prolactin yog synthesized los ntawm lactotrophs nyob rau hauv lub anterior pituitary thiab tso tawm los ntawm lub caj pas pituitary. Ntawm qhov tod tes, oxytocin yog synthesized los ntawm hypothalamus thiab tso tawm los ntawm posterior pituitary. Ntxiv mus, prolactin hormone yog lub luag haujlwm rau kev tsim cov mis nyuj, thaum oxytocin hormone yog lub luag haujlwm rau cov kua mis ejection reflex thiab uterine contraction thaum yug menyuam. Yog li, qhov no qhia txog qhov sib txawv ntawm prolactin thiab oxytocin hormone.
