pasal PREGNANCY TEST m/s 184 :

pasal indirect immunological tests : (point no 1 )

xd yg nk explain k?? huhu

saya try untuk share.tp, agak susah lah nk explain guna keyboard.ehem.

try imagine, ada satu test tube, dalam tuh ada anti-HCG dan latex coated with HCG.

1-kalau perempuan mengandung, dalam serum/urine beliau ada HCG.so, apabila urine beliau dicampurkan dalam test tube tu, HCG tu akan react with anti-HCG, so, normal reaction, no coagulation/agglutination occurs.

2-kalau perempuan tu x mengandung, serum/urine beliau tiada HCG. so, apabila urine/serum beliau dicampurkan serentak bersama anti-HCG n latex coated with HCG, anti-HCG akan react dgn HCG-coated latex tuh, so latex tuh akan caogulate, forming coagulum.

lebih kurang gini lah.maaf kalau x jelas.tapi, prosedur nih, prosedur umum utk detection antigen/antibody.mcm RIA n ELISA (not restricted to HCG only) Rolling Eyes

dia akn react mcm mane tu?? bukan k dua2 ada HCG coated kat latex tu? yg non pregnant tu faham la.. yg pregnant tu mcm confius cikit..

* dia dlm pregnant tu ada HCG kan ? so apabila dia cmpur dgn anti-HCG , so dia akan react dgn membentuk coagulum la kan?? so knpa dia x coagulated?

tp dlm case yg second, anti-HCG dia react dgn HCG yg coated kat latex kan ? so jadila coagulum..( yg ni faham )

ataupun gini :

1- HCG dlm urine tu dia react dgn anti-HCG dgn bind j ( mcm antigen bind kat receptor ) * so xjadi coagulation sebab dia xleh bind dah dgn HCG coated kat latex tu..

then , lau xd HCG dlm urine, anti-HCG tu akan bind dgn HCG yg coated tu.. so berlaku coagulation??

gitu?? btlkah conclusion ni??

testosterone tuh family androgen kan.means androgen ni ada byk (androsterone, epiandrosterone, dehydroepiandrosterone, dihydrotestosterone).

tp, specifically, interstital cell of Leydig produce testosterone, prohormone that will be converted to its active form, dihydrotestosterone.boleh refer tajuk lipid, biochem1st year.maaf kalau tersalah. Rolling Eyes

setelah berada di takuk kidney(title pun kena ada length ke?) utk tempoh yg agak lama,saya berpindah ke takuk reproduction pula,eheh,akhirnya berjaya masuk ke tajuk reproduction. (panjang lak intro)

maaf,yang ini...apakah kesudahannya? nak gak tau jawapan...atau...x penting utk written/oral??? heee.. bounce

btw, androgen lam muka surt 119(factor affecting spermatogenesis) tuh plak dtg dri mne ek?
interstitial cell of leydig? ke dye nk ckp androgen tuh sbnrnyer testosterone?

in case la kan btul androgen tuh dye nk ckp sbnrnyer adlh testosterone
pastu ayt buku ad kter cmni
'androgens through acting on sertoli cells are essential for spermiogenesis(maturation of spermatid>spermatozoa) although the earlier stages are androgen-independant'

maksudnyer, testosterone x diperlukan utk earlier stages of spermatogenesis? testosterone pelu utk spemiogenesis jer?? kerr??

p/s: sorrri, sokln mcm keling... fhm ker? sbb kepala pn tgh pusing2 ngn info2 buku

ap mksud ayt nie ek?
m/s 160
"prepubertal effect of estrogens...during childhood, estrogen are secreted at minimum level....bla bla..
the hypothalamus is hypersensitive to this low estrogen levels and hence the suppression of GnRH secretion''

progestin receptors tu ap?

progestin receptors tu ap?

tu dia nk ckp tyme prepubertal, hypothalamus has strong effect for inhibitory of gonadotrphin hormone ..
( even minimum level bleh sebabkan negetive feedbaik ) ,
*hypersensitivity ni akn hilang apabila puberty..

progestin tu bukan k progesterone tiruan untuk prevent pregnancy ??

When I was reading about;

"This increase in estrogen during follicular growth produces decrease in the rates of secretion of FSH & LH at 11th & 12th day."

but then, I continued reading;

"However, when estrogen reaches its peak secretion at 13th day, there is a sudden increase in the secretion of both FSH & LH leading to preovulatory surge of LH followed by ovulation (the estrogen feedback effect)."

Mula2, rse pelik, apehal tbe2 estrogen increases the amount of FSH & LH padahal pd mulanya die decrease-kan.

Just nk tnye pndpt korglah, betul ke ape yg ANA faham ni;

Basically, estrogen tends to give a negative feedback to hypothalamus and anterior pituitary gland to decrease the rate of secretion of FSH/LH, but during 11th & 12th day of menstrual cycle.
At 13th day, the estrogen reaches its peak sufficiently high level at 360µg/day. This gives a positive feedback to secretion of FSH/LH leading to midcycle LH surge through stimulation of pulsatile secretion of GnRH (pg. 144).

Maksudnye kat sni, ap yg ANA fahamlah, in a nutshell-nya, if the estrogen level is below 360µg/day, it tends to decrease the rate of secretion of FSH/LH, but when the estrogen level reaches its 360µg/day, this high level stimulates GnRH thus causing sudden increase of FSH/LH leading to midcycle LH surge. Kiranya yang penting kt sni adalah level of estrogen tu, kan3...

minta feedback, kalau2 silap ke... cat

rasanya tu betullah tu..pastu ada terbaca jugk yg salah satu factor dia.. pulsatile pattern of GnRH secretion tu sendiri..
dia ada monthly rhythm and hourly rhythm..

kat cini dia explain la, monthly rhythm of secretion tu salah satu factor menyebabkan LH surge ( activity positive & negative feedback )

haah, betul3...bile tgok pg. 154 baru nmpak perkaitan die...

estrogen at low and fairly high (moderate) akn indirectly stimulate inhibitory interneurons to release opiates which then inhibit GnRH at arcuate nucleus and GABA which then inhibit preoptic area.

tu kata dah, level of estrogen yg mpengaruhi secretion of FSH/LH through stimulation of GnRH...

bile die betul2 high (360microgram/day) die buat positive feedback lak kt gonadotrophs of ant. pit. gland (GnRH) thus increasing secretion of FSH/LH leading to LH surge.

Hormonal stimulation by Hormone Chorionic Somatomammotropins (HCS):

1. Secreted by placenta, has lactogenic properties.
2. Promoted during 5th week after labour.

The question, is the bold statement above right or wrongly typed?
Placenta is in the mother during pregnancy, but after labour, the placenta is expelled.
How can the HCS be promoted to the mother 5th week after labour???
