Zoo Siab

• Dab tsi yog nws rau
• LH siv qhov tseem ceeb
• Tsawg luteinizing hormone
• High luteinizing hormone

Cov tshuaj luteinizing, tseem hu ua LH, yog yam tshuaj tsim los ntawm lub caj pas pituitary thiab uas, rau cov poj niam, muaj lub luag haujlwm rau follicle maturation, ovulation thiab progesterone ntau lawm, muaj lub luag haujlwm tseem ceeb hauv poj niam kev muaj me nyuam. Hauv cov txiv neej, LH kuj tseem cuam tshuam txog kev muaj menyuam, ua haujlwm ncaj qha rau cov noob qes thiab cuam tshuam kev tsim tawm ntawm cov phev.

Hauv lub cev ntas, LH pom muaj ntau ntau dua nyob rau theem ovulatory, txawm li cas los xij nws muaj nyob thoob plaws tus poj niam lub neej, muaj ntau qhov sib txawv raws li theem ntawm kev coj khaub ncaws.

Ntxiv rau kev ua si lub luag haujlwm tseem ceeb hauv kev txheeb xyuas qhov muaj peev xwm ua tub rog ntawm txiv neej thiab poj niam, kev saib xyuas ntawm LH hauv cov ntshav pab hauv kev kuaj mob qog hauv lub qog pituitary thiab hloov cov zes qe menyuam, xws li muaj cov hlwv, piv txwv. Qhov kev ntsuam xyuas no tau thov ntau dua los ntawm tus kws kho mob poj niam muaj peev xwm kuaj xyuas tus poj niam txoj kev noj qab haus huv, thiab feem ntau tau thov ua ke nrog ntau npaum ntawm FSH thiab Gonadotropin Tso Hormone, GnRH.

Dab tsi yog nws rau

Qhov ntsuas ntawm luteinizing cov tshuaj hormones hauv cov ntshav feem ntau yuav tsum tau kuaj xyuas tus neeg lub peev xwm kev ua me nyuam thiab pab txheeb xyuas qee yam kev hloov pauv ntsig txog pituitary, hypothalamus lossis gonads. Yog li, raws li tus nqi ntawm LH hauv cov ntshav, nws muaj peev xwm ua tau rau:

• Kev kuaj mob ntxiv lawm tshob;
• Soj ntsuam lub peev xwm los ntawm cov phev los ntawm tus txiv neej;
• Kuaj xyuas yog tias tus poj niam tau nkag rau kev coj khaub ncaws;

• Kuaj seb puas muaj qe ntau txaus tsim nyog yog poj niam;
• Pab nyob rau hauv kev kuaj mob ntawm cov qog ntshav hauv lub caj pas pituitary, piv txwv.

Hauv cov txiv neej, kev tsim khoom ntawm LH yog tswj hwm los ntawm lub qog pituitary thiab ua ncaj nraim rau cov noob qes, tswj kev tsim cov phev thiab tsim cov tshuaj hormones, tshwj xeeb tshaj yog testosterone. Rau cov poj niam, kev tsim tawm LH los ntawm lub caj pas pituitary nkoos zus tau tej cov progesterone, feem ntau, thiab estrogen, yog qhov tseem ceeb rau kev xeeb tub.

Txhawm rau txhawm rau ntsuas qhov kev muaj peev xwm ntawm poj niam thiab txiv neej, tus kws kho mob kuj tuaj yeem thov kom ntsuas qhov FSH, uas yog yam tshuaj uas kuj tseem muaj nyob hauv poj niam lub cev ntas thiab muaj feem cuam tshuam rau kev tsim cov phev. Nkag siab dab tsi nws yog rau thiab yuav nkag siab li cas FSH txiaj ntsig.

LH siv qhov tseem ceeb

Qhov tseem ceeb siv rau kev luteinizing hormone sib txawv raws lub hnub nyoog, poj niam txiv neej thiab theem ntawm lub cev ntas, hauv poj niam, nrog rau cov nqi hauv qab no:

Cov Menyuam: tsawg dua 0.15 U / L;

Tus txiv neej: nruab nrab ntawm 0.6 - 12.1 U / L;

Cov poj niam:

• Txheej txheem theem: nruab nrab ntawm 1.8 thiab 11.8 U / L;
• Ovulatory peak: nruab nrab ntawm 7.6 thiab 89.1 U / L;
• Theem Luteal: nruab nrab ntawm 0.6 thiab 14.0 U / L;
• Tag nrho: nruab nrab ntawm 5.2 thiab 62.9 U / L.

Kev ntsuam xyuas cov txiaj ntsig ntawm kev ntsuam xyuas yuav tsum ua los ntawm tus kws kho mob, vim nws yog qhov yuav tsum tau soj ntsuam txhua qhov kev kuaj mob ua ke, nrog rau kev sib piv nrog cov kev xeem dhau los.

Tsawg luteinizing hormone

Thaum LH qhov tseem ceeb yog qis dua tus nqi siv, nws tuaj yeem ua pov thawj ntawm:

• Kev hloov pauv Pituitary, uas ua rau FSH txo qis thiab LH ntau lawm;
• Kev tiv thaiv tsis txaus hauv kev tsim cov gonadotropin (GnRH), uas yog yam tshuaj los tsim thiab tso tawm los ntawm hypothalamus thiab nws txoj haujlwm yog los txhawb lub caj pas pituitary los tsim LH thiab FSH;
• Kallmann's syndrome, uas yog caj ces thiab caj ces muaj kabmob los ntawm tsis muaj GnRH ntau lawm, uas ua rau muaj kev mob hypogonadotrophic hypogonadism;
• Hyperprolactinemia, uas yog qhov nce ntxiv hauv kev ua cov tshuaj hormone prolactin.

Kev txo qis hauv LH tuaj yeem ua rau txo qis phev los ntawm cov txiv neej thiab qhov tsis muaj poj niam lub cev ntas, qhov xwm txheej hu ua amenorrhea, thiab nws yog ib qho tseem ceeb kom sab laj nrog kws kho mob los qhia qhov kev kho mob zoo tshaj plaws, uas feem ntau ua nrog kev siv cov tshuaj hormonal ntxiv.

High luteinizing hormone

Qhov nce hauv LH concentration yuav yog qhov qhia tau ntawm:

• Cov qog Pituitary, nrog kev nce hauv GnRH thiab, yog li ntawd, LH tso pa tawm;
• Ntxov Ntxov;
• Cov khoom siv tsis ua hauj lwm hnyav;
• Lub sijhawm ntxov ntxov;
• Polycystic Ovary Syndrome.

Ntxiv rau, qhov LH hormone yuav nce nyob rau hauv lub cev xeeb tub, vim tias hCG hormone tuaj yeem ua qog LH, thiab tuaj yeem tshwm sim rau kev kuaj mob.
