Luteinizing hormone (LH): waa maxay iyo sababta ay u sareysaa ama u hooseysaa

• Maxaa loogu talagalay
• Qiimaha tixraaca LH
• Hormoonka luteinizing ee hooseeya
• Hormoonka luteinizing ee sareeya

Hormoonka luteinizing, oo sidoo kale loo yaqaan LH, waa hormoon ay soo saarto qanjirka 'pituitary gland' kaas oo, dumarka, uu mas'uul ka yahay qaangaarka follicle, ugxanta iyo soosaarida progesterone, oo door muhiim ah ku leh awoodda taranka haweeneyda. Ragga, LH sidoo kale waxay si toos ah ula xiriirtaa bacriminta, iyadoo si toos ah ugu shaqeysa xiniinyaha isla markaana saameyn ku leh wax soo saarka manida.

Wareegga caadada, LH waxaa laga helaa uruurinta sare inta lagu jiro wajiga ugxanta, si kastaba ha noqotee waxay ku jirtaa nolosha haweeneyda oo dhan, iyadoo leh uruurinno kaladuwan sida ku xusan wajiga wareegga caadada.

Marka lagu daro kaalin muhiim ah oo lagu xaqiijinayo awooda taranka ee ragga iyo dumarka, isku soo ururinta LH ee dhiiga ayaa ka caawisa baaritaanka burooyinka qanjirka 'pituitary gland' iyo isbedelada ku dhaca ugxan sidaha, tusaale ahaan jiritaanka burooyinka. Tijaabadani waxaa in badan codsaday dhakhtarka dumarka si loo hubiyo caafimaadka haweeneyda, waxaana badanaa laga codsadaa qiyaasta FSH iyo Gonadotropin Releasing Hormone, GnRH.

Maxaa loogu talagalay

Qiyaasta hormoonka luteinizing ee dhiiga ayaa badanaa loo baahan yahay si loo hubiyo awooda taranka ee qofka iyo ka caawinta ogaanshaha isbeddelada qaarkood ee la xiriira pituitary, hypothalamus ama gonads. Marka, marka loo eego xaddiga LH ee dhiigga ku jira, waxaa suurtagal ah in:

• Baadhitaanka madhalaysnimada;
• Qiimee awoodda wax soo saarka manida ninku leeyahay;
• Hubi inay haweeneydu daysay;
• Qiimee sababaha maqnaanshaha caadada;
• Hubi haddii ay jirto wax soo saar ukun ku filan arrinta dumarka;
• Ka caawi baaritaanka burooyinka qanjirka 'pituitary gland', tusaale ahaan.

Ragga, soosaarka LH waxaa xukuma qanjirka 'pituitary gland' wuxuuna si toos ah ugu shaqeeyaa xiniinyaha, isagoo nidaaminaya soo saarida shahwada iyo soo saarista hoormoonada, gaar ahaan testosterone. Haweenka, soosaarka LH ee qanjirka 'pituitary gland' wuxuu kiciyaa wax soo saarka progesterone, badanaa, iyo estrogen, oo muhiim u ah uurka.

Si loo qiimeeyo awooda taranka ee ragga iyo dumarka labadaba, dhakhtarku wuxuu kaloo codsan karaa cabirka FSH, oo ah hormoon sidoo kale kujira wareegga caadada haweeneyda isla markaana saameyn ku leh soo saarida shahwada. Fahmaan waxa loogu talagalay iyo sida loo fahmo natiijada FSH.

Qiimaha tixraaca LH

Qiimaha tixraaca ee loogu talagalay hormoonka luteinizing waxay ku kala duwan yihiin da'da, jinsiga iyo wajiga wareegga caadada, marka laga hadlayo dumarka, oo leh qiyamka soo socda:

Carruurta: in ka yar 0.15 U / L;

Ragga: inta udhaxeysa 0.6 - 12.1 U / L;

Haweenka:

• Wejiga follicular: inta udhaxeysa 1.8 iyo 11.8 U / L;
• Ugxanta ugu sarreysa: inta udhaxeysa 7.6 iyo 89.1 U / L;
• Wejiga luteal: inta udhaxeysa 0.6 iyo 14.0 U / L;
• Menopause: inta udhaxeysa 5.2 iyo 62.9 U / L.

Falanqaynta natiijooyinka imtixaanada waa inuu sameeyaa dhakhtarku, maadaama ay lagama maarmaan tahay in la wada falanqeeyo dhammaan imtixaannada, iyo sidoo kale isbarbardhigga imtixaannadii hore.

Hormoonka luteinizing ee hooseeya

Marka qiimaha LH ay ka hooseeyaan qiimaha tixraaca, waxay noqon kartaa mid tilmaamaysa:

• Beddelaadda Pituitary, taasoo keentay hoos u dhaca soosaarka FSH iyo LH;
• Yaraanta soo saarista gonadotropin (GnRH), taas oo ah hormoon ay soo saarto oo ay sii deyso hypothalamus oo shaqadeeduna tahay kicinta qanjirka 'pituitary gland' si loo soo saaro LH iyo FSH;
• Cudurka 'Kallmann's syndrome', oo ah cudur ku dhaca hiddo-wadaha iyo hiddo-wadaha oo lagu garto maqnaanshaha wax soo saarka GnRH, oo keena hypogonadotrophic hypogonadism;
• Hyperprolactinemia, oo ah kororka soosaarka hormoonka prolactin.

Hoos u dhaca LH wuxuu horseedi karaa hoos u dhac ku yimaada wax soo saarka shahwada ragga iyo maqnaanshaha caadada haweenka, xaalad loo yaqaan amenorrhea, waana muhiim in lala tashado dhakhtarka si loo muujiyo daaweynta ugu fiican, taas oo badanaa lagu sameeyo isticmaalka hormoonka ku darista.

Hormoonka luteinizing ee sareeya

Kordhinta fiirsashada LH waxay muujin kartaa:

• Burooyinka 'pituitary buro', oo ku kordha GnRH iyo, sidaa awgeed, dheecaanka LH;
• Qaan-gaarnimada hore;
• Xiniinyaha oo xumaada;
• Caaddo-dayska hore;
• Cudurka Polycystic Ovary Syndrome.

Intaas waxaa sii dheer, hormoonka LH ayaa lagu kordhin karaa uurka, maxaa yeelay hormoonka hCG wuxuu u ekeysiin karaa LH, wuxuuna u muuqan karaa inuu sarreeyo imtixaannada.
